Abstract:
The purpose of the present invention is to solve issues with conventional hyperthermia treatment for cancer. The present invention provides a cell activation device that is capable of suppressing the progress of cancer and contributing to the irradiation of cancer cells. This cell activation device ( 100 ) activates the gene restoration mechanism naturally hound in cells and supports cancer treatment, by cutting infrared rays having a wavelength greater than 7.5 μm at which said rays works as heat rays and irradiating infrared rays having a wavelength that equals to or is smaller than 7.5 μm on an affected area containing cancer cells. An infrared irradiation therapy using wave length of no more than 7.5 μm is a gentle therapy that activates a latent function of human cells, such as activating the gene restoration mechanism. If a type that irradiates infrared rays without contact with the patient is used, cells can be activated while the patient is leading their normal life and without restricting physical freedom.

Description:
TECHNICAL FIELD 
       [0001]    This invention relates to a cell activation device for assisting cells activation. Especially, the cell activation device works on the cancer cells and peripheral cells for activating the gene restoration mechanism included in all cells based on human nature, for restraining the cancer cells growth, and extinguishing the generated cancer cells. 
       BACKGROUND ART 
       [0002]    The current cancer treatment and therapy face many problems. If the cancer detection is made late, a complete recovery is difficult. Even if the cancer is detected successfully at an early stage, the excision surgery is not always available depending on the lesion location. In addition, side effect may accompany radiation therapy or chemotherapy. Even if cancer is detected is successfully at an in early stage and the lesion portion is accessible to excision, such surgical treatment is an invasive treatment method that injures the human body. 
         [0003]    In light of the current situation, the research of the cancer treatment and the development of the cancer treatment medical devices are actively performed, but a decisive cancer treatment method has not been found. 
         [0004]    Among the prior art, a prior art relating to the cancer treatment method using the thermotherapy is known as a non-invasive treatment (prior art 1: JPA2003-126275). According to the prior art 1, the infrared ray which mainly works as a heating ray is irradiated to the lesion or whole body on the assumption that the cancer cell is susceptible to high temperature. This thermotherapy requires enhancing the deep body temperature at the lesion part up to 41° C. to 42° C. 
         [0005]    The prior art 1 discloses the technology for enhancing the deep body temperature at the lesion part up to 41° C. to 42.5° C. by containing the patient in a capsule container that can contain his body except for his head air tightly, and irradiating the infrared ray with an infrared irradiator. The patient&#39;s whole body except for his head is heated by the radiant heat of the infrared ray and the conductive heat of the air in the capsule container.
   Patent prior art 1: JPA2003-126275   
 
       DISCLOSURE OF THE INVENTION 
     The Problems to be Solved 
       [0007]    The conventional technology described in the prior art JPA2003-126275 has the following problem. According to the conventional technology described in the prior art JPA2003-126275, the blood temperature will be enhanced up to 45° C. 46° C. in order to enhance the whole body temperature or the deep body temperature at the lesion part up to 41° C. to 42° C. However, the conventional treatment term is delayed up to one hour because a preliminary treatment such as an administration of heparin will be required in order to prevent blood from coagulating. The treated patient may be too damaged to stand up for a few days due to a physical burden upon receiving the conventional treatment. 
         [0008]    In addition, according to the conventional technology described in the prior art 1, when the radiant heat of the infrared ray is applied to the patient in order to increase the body temperature up to 41° C. to 42° C., the temperature of the skin surface will be increased to more than 65° C., and the patient will suffer a low temperature burn during the long term irradiation. From this point of view, the conventional treatment term should be limited to up to one hour. 
         [0009]    On the otherhand, the patient body temperature should be constrained to lower than to 43° C. within the physiological range for the normal cells. Therefore, it is difficult to achieve both the temperature at which the normal cells are protected within the physiological range and the temperature of the cancer cells is increased up to 41° C. to 42° C. at the same time. 
         [0010]    Therefore, it is an object of the present invention to provide a cell activation device that can activate the gene restoration mechanism included in all cells based on human nature and obtain the cell activation efficacies by irradiating the infrared ray. 
       Means for Solving the Problems 
       [0011]    Mr. Hiroki SHIMA, the inventor of the present invention has worked on researching the cancer treatment as a doctor, and discovered the more effective cancer treatment than the conventional cancer treatment. Mr. Hiroki SHIMA&#39;s research is highly evaluated in the world, and his thesis is published on the British science specialized magazine Nature (Nature Preceding: hdl: 10101/npre. 2008.1980.1: Posted 17 Jun. 2008). 
         [0012]    The cell activation device of the present invention is developed by the inventor Mr. Hiroki SHIMA based on the newly obtained findings in this research. His invention can activate the gene restoration mechanism included in all cells based on human nature by irradiating the infrared ray by the different means from the conventional method. 
         [0013]    In order to achieve the above-mentioned object, the present invention is a cell activation device for irradiating the infrared ray to the cells. It comprises a heat source, a temperature controller and an infrared ray irradiator. The radiation ray wavelengths emitted by the infrared ray irradiator are controlled by the temperature controller, and only the infrared ray whose wavelength equals to or is smaller than 7.5 μm (wavelength equal to or larger than that of the visible light and equal to or smaller than 7.5 μm) from the infrared ray irradiator is selectively utilized to irradiate onto the cells. 
         [0014]    It is preferable that the cell activation device further comprises a filter that passing only the infrared ray whose wavelength equals to or is smaller than 7.5 μm that is installed onto the surface of the infrared ray irradiator. The filter can cut-off the infrared ray whose wavelength is larger than 7.5 μm mainly working as a heating ray, and passes only the infrared ray whose wavelength equals to or is smaller than 7.5 μm for irradiating onto the cells. 
         [0015]    In the above configuration, it is preferable that fine holes are installed onto the infrared ray irradiator. If the diameter of the fine hole equals to or is smaller than 15 μm, the infrared ray irradiator does not irradiate the infrared ray whose wavelength is larger than 7.5 μm mainly working as the heating ray but irradiates the infrared ray whose wavelength equals to or is smaller than 7.5 μm onto the cells. 
         [0016]    In the above configuration, it is preferable that the depth of the fine holes of the infrared ray irradiator becomes larger than the diameter of the fine holes in order to obtain the radiation directivity for the infrared ray irradiator. 
         [0017]    It is preferable that the cell activation device further comprises a first filter that is a hydrophilic filter having a quartz glass container filled with water and a second filter that can cut-off the infrared ray whose wavelength is larger than 7.5 μm mainly working as a heating ray. 
         [0018]    In the above configuration, it is preferable that the temperature control part can maintain the temperature distribution of the heat source constant, and can maintain the surface temperature of the infrared ray irradiator within the particular temperature range. 
       Effect of the Invention 
       [0019]    According to the above-mentioned configuration of the invention of a cell activation device, the infrared ray that works as a heating ray to the patient body is cut-off and the infrared ray whose wavelength equals to or is smaller than 7.5 μm is selectively passed through for irradiating onto the cells in order to activate the gene restoration mechanism of each cell. By activating the gene restoration mechanism, the cell activation device can convert the cancer cells into the normal cells or can annihilate the cancer cells by activating the apoptosis process. The cell activation device also can constrain the conversion of the peripheral normal cells into cancer cells. 
         [0020]    In addition, the cell activation device may be useful for the prophylaxis of other diseases in addition to the prophylaxis of cancer because the normal cells are activated.

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0046]    Some embodiments of a cell activation device according to the present invention are described below with reference to the relevant drawing. Needless to add, the claims of the present invention include but are not limited to the configuration and numerical value shown in the following embodiments. 
       Embodiment 1 
       [0047]    First, the experiment that shows the basic principle of the cell activation device  100  is described below. 
         [0048]      FIG. 1  is a schematic drawing showing the experiment for verifying the effect on the human cancer cells by the infrared ray irradiation whose wavelength equals to or is smaller than 7.5 μm by using the test sample of the cancer cells. 
         [0049]    As shown in  FIG. 1(   a ), a test sample  10  and culture solution  20  are put on the petri dish  40 . An infrared ray irradiator material  30   a  is installed on the petri dish  40  and an infrared ray irradiator material  30   b  is installed beneath the petri dish  40 . 
         [0050]      FIG. 1(   b ) is a schematic drawing showing the cross-sectional view of the each component shown in  FIG. 1(   a ). 
         [0051]    The test sample  10  is a tissue including human cancer cells. As an example, the human derived prostatic cancer cells are prepared. 
         [0052]    The popular culture solution may be employed as the culture solution  20 . As an example, an amino acid solution including the fetal calf serum, L-glutamine and penicillin is prepared. 
         [0053]    The infrared ray irradiator  30   a  and  30   b  are the material which can irradiate the infrared ray. In this experiment, a rubber material (Bio rubber (trademark): made by Yamamoto Corporation Co., Ltd.) is used. It has fine holes on the surface of the rubber plate for reflecting the infrared ray emitted from the human body.  FIG. 2  is a graph showing a spectral reflectance of the special rubber material used in the present experiment. As shown in  FIG. 2 , the spectral characteristics of the infrared ray irradiator  30   a  and  30   b  have flat constant spectral characteristics for the 1 to 20 μm range. 
         [0054]    The petri dish  40  made from polystyrene is used. The spectral transmittance of the petri dish  40  is shown as  FIG. 3 . As shown in  FIG. 3 , most of the infrared ray whose wavelength equals to or is larger than 5 μm is cut-off, especially the transmittance of the infrared ray whose wavelength is larger than 7.5 μm is zero. In  FIG. 3 , a spectral transmittance of the petri dish used in this experiment and a spectral transmittance of the flexible disk used in this experiment are shown together. A spectral transmittance of silicon (Si) is also shown together in  FIG. 3 . The spectral transmittance of the silicon (Si) has flat constant spectral characteristics. The filter including silicon material is described later on. 
         [0055]    The petri dish  40  works as a filter in the experiment shown in  FIG. 1 . The infrared ray whose wavelength is larger than 7.5 μm among the infrared ray emitted from the infrared ray irradiator  30   a  and  30   b  is selectively cut-off by the petri dish  40 . Therefore, only the infrared ray whose wavelength equals to or is smaller than 7.5 μm can be irradiated to the test sample  10 . 
         [0056]    The experiment apparatus shown in  FIG. 1  is set in an incubator, which means a culture solution installed in a heat-retaining container, the temperature is maintained in 37° C. and the concentration of carbon dioxide gas is maintained in 5% as in a popular cultivation experiment. 
         [0057]    After the experiment is started with the infrared ray irradiator  30   a  and  30   b,  the temperature of the culture solution  20  in the petri dish  40  became a little bit higher up to 37.68° C. because of the infrared ray emitted from the infrared ray irradiator  30   a  and  30   b  in addition to the heat derived from the cell proliferation. On the contrary, after the experiment is started without the infrared ray irradiator  30   a  and  30   b,  the temperature of the culture solution  20  in the petri dish  40  became 37.32° C. because of the heat derived from the cell proliferation being generated. 
         [0058]    The experiment term is 28 days. During the experiment term, the temperature of the incubator is always maintained to 37° C. The temperature of the test sample  10  reaches 37.68° C. and the cultivation of the test sample  10  is going on for 21 days. After 21 days cultivation, surviving cancer cells is collected and the number of the surviving cancer cells is counted up, and then each cancer cells are put back in the cultivation solution  20  in the petri dish  40  again. Further 7 days cultivation is carried out, and then the cancer cells are collected and the number of the surviving cancer cells is counted up on the 29th day. The number of the surviving cancer cells is counted by XTT assay kit. As the XTT assay kit, the Cell Proliferation Kit II (Roche Diagnostics, Mannheim, Germany) is used. 
         [0059]    The experiment result is shown in  FIG. 4 . The schematic chart described the increasing rate (%) of the number of the surviving cancer cells on the 29th day on the basis of the number on the 21st day. 
         [0060]    As the experiment result, if the experiment started with the infrared ray irradiator  30   a  and  30   b,  the number of the cancer cells is decreased 58.5% down to 41.5% compared with the case when the experiment started without the infrared ray irradiator  30   a  and  30   b.  Regarding the normal cells (human epithelial cells), if the experiment started with the infrared ray irradiator  30   a  and  30   b,  the number of the normal cells is increased 69.5% up to 169.5% compared with the case when the experiment started without the infrared ray irradiator  30   a  and  30   b.    
         [0061]    There should be two possible reasons for annihilating 58.5% of the cancer cells. The first reason is that when the temperature of the cultivated solution  20  reaches 37.68° C., the apoptosis mechanism is activated in the cancer cells and the cancer cells annihilate themselves itself as shown in the upper portion of  FIG. 1(   c ). The second reason is that the gene restoration mechanism included in all cells is activated in the cancer cells and the speed of the cell proliferation become small because the cancer cells are converted into the normal cells as shown in the middle portion of  FIG. 1(   c ). As shown above, it is understood from the experiment that the gene restoration mechanism is activated and the number of the cancer cells is decreased, and the cancer cells are converted into the normal cells. 
         [0062]    Regarding the normal cells (human epithelial cells), the normal cells are activated for cell proliferation and the gene restoration mechanism is also activated. On the otherhand, the apoptosis mechanism is not activated in the normal cells. If the gene is damaged in the normal cells, the damaged gene can be restored before the apoptosis mechanism is activated. 
         [0063]    The reason for the activation of the gene restoration mechanism is not simply because of the temperature up to 37.68° C. but because the infrared ray emitted from the cells accompanying the cell proliferation is reflected by the infrared ray irradiator  30   a  and  30   b,  and the infrared ray whose wavelength is larger than 7.5 μm is cut-off by the material of the petri dish  40 , and the infrared ray whose wavelength equals to or is smaller than 7.5 μm is irradiated to the depth portion of the test sample  10 . 
         [0064]    Hereinafter, the possibility that the infrared ray whose wavelength equals to or is smaller than 7.5 μm can reach to the depth portion of the sample  10  is described. As described above, in the experiment apparatus shown in  FIG. 1 , the petri dish  40  works as a filter for cutting off the infrared ray whose wavelength is larger than 7.5 μm and passing through the infrared ray whose wavelength equals to or smaller than 7.5 μm among the infrared ray emitted from the infrared ray irradiator  30   a  and  30   b  at 37.68° C. 
         [0065]    The infrared ray whose wavelength equals to or is smaller than 7.5 μm passing the petri dish  40  lid passes through the atmosphere including 5% concentration of carbon dioxide gas and further passes through the cultivation solution, cell wall and cytoplasm. As shown in  FIG. 5 , the infrared ray whose wavelength equals to or smaller than 7.5 μm can pass through the carbon dioxide gas judging from the spectral transmittance of the carbon dioxide gas and its absorption spectrum. 
         [0066]    There are a lot of fine holes whose diameter is 2 to 7 μm in the cell such as the fine holes on the surface of the mitochondria. Therefore, the infrared ray whose wavelength is smaller than the diameter of these fine holes can enter the inside of the cytoplasm via the cell wall. Regarding the cytoplasm, about 90% of the human body is composed of water. As shown in  FIG. 5 , the infrared ray whose wavelength equals to or is smaller than 7.5 μm can pass through the water judging from the spectral transmittance of the water molecule. 
         [0067]    Considering the experiment result, the infrared ray whose wavelength equals to or is smaller than 7.5 μm can reach a depth portion of the test sample  10  and activate the gene restoration mechanism and the apoptosis mechanism in the cancer cells in the test sample  10 , and the number of the cancer cells is decreased. 
         [0068]    Next, the characteristics of the bio rubber (trademark) used as the material of the infrared ray reflection. 
         [0069]    The bio rubber (trademark) used as the material of the infrared ray reflection in the experiment is normally used as the material for body suits having the characteristics of the infrared ray reflection. In short, bio rubber (trademark) is used as the suit material for wet suits to put on the human body for warming the user body by reflecting the infrared ray emitted from the human body back to the human body. Therefore, if the user puts bio rubber (trademark) suits on the body as usual, only the infrared ray emitted from human body at the temperature of 36.5° C. is returned to the user body. The strength of the required infrared ray wavelength radiation is deficient. 
         [0070]      FIG. 6  is a schematic drawing showing an effect on the human cancer cells on the condition that the infrared ray emitted from the human body is reflected to the human body by using the bio rubber (trademark) without using the heat source. A node mouth is used in this experiment. The filter for adjusting the infrared ray wavelength is not installed in this experiment. In  FIG. 6 , the bio rubber (trademark) is shown only on the upper side of the gauge, and others on the other surfaces are omitted here. However, all surfaces such as the side surface and bottom surface are covered by bio rubber (trademark) plates. 
         [0071]    As shown in  FIG. 6 , test mouse  300   a  and  300   b  onto which the cancer cells are implanted are put in gauge  200   a  and  200   b  respectively. All surfaces of the upper gauge  200   a  are covered by the bio rubber (trademark) as the infrared ray irradiator  110 . The lower gauge  200   b  is not covered by the bio rubber (trademark) at all. 
         [0072]    3 millions of human prostate cancer cells are implanted to the hypodermic tissue of the back skin of the node mouse  300   a  and  300   b  respectively and the growth of the cancer cells is observed. The mouse does not have T-cell, so there is no rejection reaction caused by the cancer cells. The infrared ray whose wavelength equals to or is smaller than 7.5 μm is always irradiated to the node mouse  300   a  in the gauge  200   a,  but the infrared ray which wavelength equals to or smaller than 7.5 μm is not always irradiated to the node mouse  300   b  in the gauge  200   b.  Other conditions are the same. 
         [0073]    The mouse  300   a  and the mouse  300   b  are emitting the infrared ray corresponding to its body temperature. There is the infrared ray irradiator  110  is installed in the gauge  200   a,  so the emitted infrared ray is reflected from the infrared ray irradiator  110  to the mouse  300   a.    
         [0074]    The temperature in the gauge is maintained as 23° C. and the humidity in the gauge is maintained as 40%. The experiment is conducted for 93 days. The experiment result is shown in  FIG. 7 . If the mouse is bred in a natural condition, the number of the human cancer cells keeps on increasing during the experiment term because the cancer cells proliferate in the mouse body freely. As shown in  FIG. 7 , the number of the cancer cells in the mouse  300   b  bred in the gauge  200   b  in which the infrared ray is not irradiated back to the mouse is increased to the end. On the otherhand, the number of the cancer cells in the mouse  300   a  bred in the gauge  200   a  in which the infrared ray is irradiated back to the mouse is increased from the beginning up 70 days, but turned to decreased over 70 days. This result indicates the effect on the restraint of the proliferation of the cancer cells by irradiating the infrared ray by reflecting the emitted infrared ray from the body though requiring a long period of time for 70 days. 
         [0075]    However, as shown in  FIG. 4 , the effect on the restraint of the proliferation of the cancer cells by irradiating the infrared ray whose wavelength equals to or is smaller than 7.5 μm is verified enough. If the infrared ray emitted from the mouse is reflected by the bio rubber (trademark) without any heat source as shown in  FIG. 6 , the irradiation intensity of the effective infrared ray whose wavelength is smaller than 7.5 μm is not enough. Therefore, it takes 70 days to show the distinguishable effect on the restraint of the proliferation of the cancer cells. 
         [0076]    The reason for the slow-acting of the effect on the restraint of the proliferation of the cancer cells is the deficiency of the infrared ray whose wavelength is smaller than 7.5 μm by utilizing only the infrared ray emitted from the human body (mouse) by putting the bio rubber (trademark) as the infrared ray irradiator  110  on the human body (mouse). 
         [0077]    The cell activation device  100  of the present invention includes a heat source for enhancing the irradiation intensity of the effective infrared ray whose wavelength is smaller than 7.5 μm in order to obtain the distinguishable effect on the restraint of the proliferation of the cancer cells earlier. 
         [0078]    The cell activation device  100  of the present invention employs the infrared ray reflection material for irradiating the infrared ray whose wavelength is smaller than 7.5 μm, and the gene restoration mechanism is activated in the normal cells and the cancer cells by irradiating the infrared ray to the lesion. 
         [0079]    The cell activation device  100  of the present invention is provided as the non-contact style device. The conventional bio rubber is provided as a wear material for contacting human body. The patient cannot help wearing the bio rubber (trademark) for 24 hours if the infrared ray irradiation is required constantly, but it is inconvenient for the patient because the freedom of behavior of the patient is deprived 
         [0080]      FIG. 8  is a schematic drawing showing a basic configuration of a cell activation device  100  of the present invention. 
         [0081]    As shown in  FIG. 8 , the basic configuration of the cell activation device  100  can irradiate the infrared ray whose wavelength is smaller than 7.5 μm and it is a non-contact style device apart from the lesion of the patient for irradiating the infrared ray whose wavelength is smaller than 7.5 μm from the outside. 
         [0082]    As shown in  FIG. 8 , the cell activation device  100  includes the infrared ray irradiator  110 , the heat source  120 , the infrared ray wavelength controller  130  and the temperature controller  140 . 
         [0083]    The infrared ray irradiator  110  is a material irradiating the infrared ray depending on the temperature of the material. The material is not limited as long as the material can emit the infrared ray proportional to the temperature of the object. For example, the bio rubber (trademark), the ceramics such as tile, the metal material such as the bronze plate and the aluminum plate can be employed as this material. 
         [0084]    The heat source  120  generates and supplies heat to the infrared ray irradiator  110 . The heat source  120  is not limited if it can control the heat amount and temperature. For example, the device which can control the electric current and voltage such as a plate heat device can be employed. 
         [0085]    The infrared ray wavelength controller  130  cuts off the infrared ray whose wavelength is larger than 7.5 μm working as a heating ray and passes through the infrared ray whose wavelength equals to or is smaller than 7.5 μm. In this example, it is an optical filter. As the material for the filter, the bio rubber (trademark), water, or polystyrene resin can be applicable. Other material beside water and polystyrene resin can be used as long as it has characteristics for cutting off the infrared ray whose wavelength is larger than 7.5 μm and passing through the infrared ray whose wavelength equals to or is smaller than 7.5 μm. 
         [0086]    If the filter should be cooled in order to avoid the temperature becoming too high by the heat, various cooling devices such as the heat dissipation through heat conduction using heat sink, the air cooling or the liquid cooling using heat medium and the cooling device using coolant can be applicable. 
         [0087]    The temperature controller  140  is a controller for fine controlling the temperature of the heat source  120 . 
         [0088]    There are varieties of controlling processes for the temperature controller. Such controlling processes are conventional technology, and are not limited. In this example, the temperature controller  140  includes the voltage controller device for adjusting the temperature by utilizing the input voltage (AC 100V). 
         [0089]    By using those elements, the cell activation device  100  of the present invention can cut off the infrared ray whose wavelength is larger than 7.5 μm and pass through the infrared ray whose wavelength equals to or is smaller than 7.5 μm. 
         [0090]    As shown in  FIG. 8 , it is possible to achieve the non-contact device that can irradiate the required amount of the infrared ray for activating the cell. This non-contact device can cut off the infrared ray whose wavelength is larger than 7.5 μm working as a heat ray and passes through the infrared ray whose wavelength equals to or is smaller than 7.5 μm for activating the apoptosis mechanism for annihilating the cancer cells. 
         [0091]      FIG. 9  is a schematic drawing showing a basic configuration of a cell activation bed employing the cell activation device. As shown in  FIG. 9 , the heat source, the infrared ray irradiating object and the filter are installed beneath the bed. The patient is always exposed to the infrared ray whose wavelength equals to or is smaller than 7.5 μm irradiated under the bed if the patient lies down the bed. The heat radiation countermeasure should be conducted to avoid heat retention beneath the bed. 
         [0092]    The bed shown in  FIG. 9 , includes the heat source  120 , the infrared ray irradiator  110  and the filter  130  beneath the bed. Other configurations of the non-contact device are possible. For example, a ceiling light includes the heat source  120 , the infrared ray irradiation object  110  and the filter  130  in order to irradiate the infrared ray whose wavelength equals to or is smaller than 7.5 μm over the head of the patient. 
         [0093]    Next, the principle to attain cancer treatment closer to natural healing to the cancer cells by activating the gene restoration mechanism is described. 
         [0094]    There are still many uncertainties as to the cause of the generation of the cancer, but one cause is the damage to the gene injured for some reason. The gene restoration mechanism is included in all cells based on the human nature to restore the damaged gene to the normal gene. When the gene is damaged in each cell, the damaged gene is restored by the gene restoration mechanism. 
         [0095]    However, when the gene restoration cannot catch up with the gene deterioration by the decrease of the gene restoration rete accompanying the cell aging or the increase of the gene damage rate due to the environmental factor, the cell is classified into 3 patterns. The first pattern is the cell that goes into the dormant status of being irreversible called the aging (aging of cell). The Second pattern is the cell that kills itself called the apoptosis or the programmed cell death. The third pattern is the cell that converts into cancer. As a result, some cells convert into cancers unless the damaged gene is not restored to the normal gene. If the cell is converted into the cancer cell, the cancer cell will proliferate as a cancer cell. 
         [0096]      FIG. 10  is a schematic drawing showing a gene restoration mechanism. It shows the restoration cycle for restoring the damaged gene to the normal gene in each cell. If the gene restoration mechanism is activated, the damaged gene in the cancer cell is restored to the normal gene and normal cell. 
         [0097]    The cancerous growth is caused by repeating the cell proliferation for generating new cancer cell because the gene restoration mechanism in the cell does not work normally. 
         [0098]    The cell activation device  100  can convert the damaged cancer cells into the normal cells by activating the gene restoration mechanism included in all cells based on human nature and can annihilate the damaged cancer cells by promoting the apoptosis in the cancer cells. In addition the cell activation device  100  can protect the conversion of the normal cells around the cancer cells into the new cancer cells. 
         [0099]    Next, the effect of the cancer cells by irradiating the infrared ray whose wavelength equals to or is smaller than 7.5 μm is verified as follows. 
         [0100]    The human cancer cells are cultivated with irradiation of the infrared ray whose wavelength equals to or is smaller than 7.5 μm for 28 days and the human cancer cells is put into the petri dish having 35 mm diameter on 29th day and observed. As shown in  FIG. 11(   a ), the nuclei of the cancer cells are dyed with propidium iodide followed by dying of TUNEL (Terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP)-digoxigenin nick end labeling (TUNEL)), and the apoptosis working in the processed cancer cells are observed by the fluorescence microscope. The apoptosis is observed in the cell (indicated by arrow) among cancer cells exposed to the infrared ray whose wavelength equals to or is smaller than 7.5 μm. 
         [0101]    As shown in  FIG. 11(   b ), the processed cancer cells are observed at magnification of 10,000 times by the electron microscope. The apoptosis characteristics such as the swelling of the mitochondria, the blurring of the crista, the swelling and the corrugating of the nuclear membrane and the vacuolation of the cytoplasm are observed in the cancer cell in the experimental group while irradiating the infrared ray whose wavelength equals to or is smaller than 7.5 μm. 
         [0102]    As shown above, the gene restoration mechanism in each cancer cell is activated by irradiating the infrared ray whose wavelength equals to or is smaller than 7.5 μm. The effect on converting the cancer cells into the normal cells, annihilating the cancer cells, and preventing the normal cells around the cancer cells from converting into the cancer cells are verified through the above-mentioned experiment. 
         [0103]    In the above experiment, the temperature of the object is discussed to express the infrared ray wavelength. It is known that the energy amount obtained by the wavelength of the infrared ray and the frequency is proportional to the temperature of the object. 
       Embodiment 2 
       [0104]    As shown in  FIG. 8 , the configuration shown in Embodiment 1 employs the filter as an element for cutting off the infrared ray whose wavelength equals to or is smaller than 7.5 μm. However, the element for cutting off the infrared ray whose wavelength equals to or is smaller than 7.5 μm is not limited to the filter. Other elements can be employed instead of the optical filter. The embodiment 2 of the configuration of the cell activation device employing other element instead of the optical filter is described below. 
         [0105]    The plate object having fine holes on the surface can be employed as an alternative of the optical filter. The object having fine holes which diameter is as twice as the wavelength of the infrared ray to be cut off can be an alternative element instead. For example, the resin plate object, the ceramics plate and other material can be employed as an alternative object. The object having fine holes on its surface has characteristics such that the ray whose wavelength larger than ½ of the diameter of the fine holes is cut off. If the diameter of the fine holes is 15 μm, the object has the same characteristics as the filter whose cut-off wavelength is 7.5 μm, so the alternative object can cut off the infrared ray whose wavelength is larger than 7.5 μm. 
         [0106]      FIG. 12  is a schematic drawing showing a basic configuration of a cell activation device  100   a  of Embodiment 2. 
         [0107]    As shown in  FIG. 12 , the cell activation device  100   a  of Embodiment 2 includes a ceramic  130   a  such as ceramic plate having a high emissivity for the infrared ray, and the ceramic  130   a  has fine holes whose diameter is 15 μm on its surface. Another plate object besides the ceramic  130   a  can be employed if the fine holes can be installed on the surface. 
         [0108]    In the configuration shown in  FIG. 12 , the infrared ray whose wavelength equals to or is smaller than 7.5 μm is passed through the plate object, and the infrared ray whose wavelength is larger than 7.5 μm is cut off by the plate object among the infrared ray emitted from the infrared ray irradiator  130   a.  The cut-off infrared ray whose wavelength is larger than 7.5 μm is once absorbed in the plate object and re-emitted from the plate object according to the temperature of the plate object. Some of them are re-emitted as the infrared ray whose wavelength equals to or is smaller than 7.5 μm. Therefore, it is useful for enhancing the high infrared radiation efficiency. 
         [0109]    It is possible for the plate object to give directivity to the infrared ray.  FIG. 13  is a schematic drawing showing the relationship between the depth (d) and the diameter (r) of the fine holes and the directivity of the reflected infrared ray. It is known that the directivity is given to the infrared ray by the relationship between the depth (d) and the diameter (r) of the fine holes installed on the surface of the ceramics  130   a  working as the irradiating material of the infrared ray. If the depth of the fine holes is larger than the diameter of the fine holes, the directivity of the emitted infrared ray is enhanced. By utilizing these characteristics, if there is a certain distance from the non-contact type cell activation device of the present invention to the patient lesion (for example, in a range from dozens of centimeters to about over ten meters), the preferable amount of the infrared ray can be irradiated to the patient lesion. In the above-mentioned example, the ceramic is employed as the irradiator material, but another plate object such as rubber plate can be employed instead if the fine holes with the predetermined diameter can be installed on its surface. 
         [0110]    Next, a hydrophilic filter having a quartz glass container filled with water can be employed as an alternative of the optical filter.  FIG. 14  is a schematic drawing showing the water filter  130   b  filled with water in the quartz glass container. The spectral transmittance of a quartz glass for the infrared ray whose wavelength is 1 to 10 μm is almost a constant level. Therefore, the efficiency of the water filter  130   b  filled with water in the quartz glass container depends on the spectral transmittance of water. Water cuts off the infrared ray whose wavelength is larger 7.5 μm and passes through the infrared ray whose wavelength equals to or is smaller than 7.5 μm. Therefore, the water filter  130   b  filled with water in the quartz glass container can be an alternative element of the optical filter  130  working as the infrared ray wavelength controller shown in embodiment 1. However, the water filter passes the infrared ray whose wavelength is larger than 10 μm, so it is preferable that another optical filter that cuts off the infrared ray whose wavelength is larger than 10 μm is employed together with the water filter  130   b.    
         [0111]    While some preferable embodiments of the cell activation device according to the present invention are described above, it should be understood that various changes are possible, without deviating from the technical scope according to the present invention. Therefore, the technical scope according to the present invention is limited only by the claims attached.
