## Background
TECHNICAL FIELD
The present invention relates to an antipyrotic and a method of manufacturing the same. More particularly, it relates to a cream that is excellent for treating skin burn (also referred to as “burn”) by adding, in a fixed ratio, compositions excellent for treating burn wounds to usual cream or ointment for skin application, and a method of manufacturing the same.
BACKGROUND ART
Ever since the first discovery of fire by mankind, fire has become one of those things which have important meaning in the history of civilization and is indispensable in man's life. But fire also has become one that gives damage to mankind due to careless usage and the damage was big. Burn is one of those damages from wrong usage. Bum can be as slight as burn by solar heat, and it can be so frightening as to lead to death when it is serious.
The causes of burn are mainly accidents at home and half of them can be prevented and carelessness is the main causes of them. Burn is classified into first degree, second degree, third degree, and fourth degree and this classification is important in taking a measure for treatment. The first degree burn is instantly generated when taking strong solar rays in the beach or when contacting exploding gases or hot liquids instantaneously and the affected region may be accompanied by pain and redness and may be healed without trace after a few days without special treatment. The second degree burn also is accompanied by redness and blisters are formed in the affected region, which appears to be somewhat swollen compared to the surrounding tissues. It is accompanied by serious pain and can leave scars after complete healing. The third degree burn is the case where all the layers of skin including epidermis and dermis are damaged, and the skin is dried and turned into white or black as if it is burned and loses the sense. Lastly, the fourth degree burn is a term that started to be used recently and is the case where hypodermic muscles, tendons, nerves, and skeleton tissues are damaged, along with all the skin layers.
As explained in detail above, the degree of burn is classified into first, second, third, and fourth, according to the area and depth of burn, and the causes of burn can include those by current, chemicals, heat, etc. Anyone can get burned slightly or seriously due to carelessness or unexpected accidents.
In the case of getting burned, the first treatment is the most important. If it is not treated properly or treated wrong in emergency, it can leave scars and the treatment period can be lengthened and other skin diseases can be accompanied.
By the way, when the burn is serious at home or in industry, the patient is moved to the hospital immediately, but when the patient or the patron determines it is not serious, he or she relies on self-treatment and often neglects the affected region. Meanwhile, the traditional treatments such as pouring “soju” of distilled liquor onto the affected region or applying soy sauce or sesame oil are known as an emergency treatment or measure for burn, but such treatments can never be an emergency treatment or measure and can only aggravate the affected region. In this case, an emergency treatment that can be executed at home easily and effectively is to let the affected region cool with tap water (cool water), and this has proven to be effective medically.
Meanwhile, general antipyrotic can include Vaseline gauze, ointment for skin disease for treating slight burn, M ointment of cream type containing beta-sitosterol of D chemicals, etc.
However, such conventional antipyrotic have the following problems. The gauze-typed antipyrotic isolates the affected region from outside air and this may delay recovery. Also, when the burn is suppurative, secretions and suppurative meterials can be attached to the gauze, and it can give pain to the patient when the gauze is substituted. Furthermore, the conventional antipyrotic are not excellent in their effects.
In other words, these conventional antipyrotic did not reach a satisfactory level in terms of treatment of burns, and in particular, it has a long way before an easy treatment for slight burn such as first and second degree burn is developed.
Therefore, to solve the problems mentioned above, the present inventor found a natural substance having remarkable results in treatment of burn, and completed this invention by applying the substance to the cream for treating burn.
DISCLOSURE OF THE INVENTION
Therefore, it is an object of the present invention to provide a cream or ointment type of antipyrotic that can easily treat, with excellent treating power, slight burn that does not require special treatment by medical specialists.
Another object of the present invention is to provide a cream or ointment type of antipyrotic that do not leave irreparable scars after treatment
Still another object of the present invention is to provide low-priced antipyrotic, which can avoid ill practice of interrupting treatment due to expensive medical expanses of burn treatment and other burdens by making it possible to treat burn easily.
Yet another object of the present invention is to provide a method of easily manufacturing the antipyrotic mentioned above.
The present invention provides an antipyrotic including carbonized pine cones in a broad sense according to the present invention.

Therefore, the detailed explanation below should be viewed as for only illustrating a preferred embodiment.
In order to achieve the above objects of the present, according to one aspect of the present invention, there is provided an antipyrotic having, as its main composition, a carbonized pine cone that is yielded by completely combusting selected pine cones put in a sealed container after washing and drying at a temperature of 100 to 300° C. and having, as an additive, a normally used carrier.
As mentioned above, the pine cone used as the main composition of the present invention is the seed of pine. Pine can be called Sol, Chamsol, Songmok, Solnamoo, Sohorinamu in Korea. Pine also is called red pine since the bark and the bud is red. It is also called female pine, Japanese red pine, Yodong red pine, unifoliate red pine in China. Pine is bifoliate, where two leaves form a couple. It is also called Isoosong, Ichimsong (denoting two-needle pine), Iripsong, etc., and all these names represent pine is bifoliate. Scientific term of pine is Pinus densiflora Siebold et Zuccarini. When pine seed pushes out new shoots, shoots with the testa come out above earth, and the number of shoots is about 4 to 9 and is 6 in most cases. Pine leaves deviating the shoots form a couple and come out with one confronting the other and the bottom portion is in the vagina that is about 2 or 3 mm in size. The vagina is dark brown and is alive as long as the leaves, without falling down. Meanwhile, there are female and male flowers in pine, which bloom in the last ten days of April and the first ten days of May. The male flower is elliptical and 4 to 9 mm in length. The end of the stamen spreads in the shape of the half moon and there are two anthers below filements. There are two wings in pollen. Meanwhile, the female flower is hung 2 or 3 at the end of the branch. The initial shape is circular or elliptical and is about 5 mm in length and is light violet in color. This is a collection of a multitude of female flowers, which is called a cone. This is what is called a pine cone in the present invention. Mature pine cones consist of various scaly leaves, and in a scaly leaf, two ovules are in contact, which later on become a seed with two wings. Young cones in spring before pollination are called storbile or conelet in English, instead of cones. Scaly leaves of the pine cone is in contact with the axis of the pine cone helically, its end is fat and big, its exposed part is near the diamond shape, and there is a protrusion in its center. When the pine cone is mature, the gap between scaly leaves become bigger and the seeds are fallen apart and come flying out.
Meanwhile, according to the present invention, the sesame oil may be added to the antipyrotic of the present invention whose main composition is the carbonized pine cone.
Preferably, the sesame oil may be added 1:1 to 2:1 in the weight ratio compared to the weight of the pine cone to the antipyrotic of the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described hereinafter in detail with reference to examples and experiments, but the present invention is not limited to them.


EXAMPLE 1
First, the pine cones with uniform size were selected from the natural species of pine cones. They were washed with purified water and dried in the shade. After confirming whether they were well dried, 1000 g of the dried pine cones were put in a sealed container if they are well dried and completely combusted for 2 hours at 200° C.
After complete combustion, they were left alone for 1 or 2 hours to let them cool, thereby yielding the carbonized pine cone. The latter pine cone was sieved, thereby yielding about 800 g of the carbonized pine cone powder that is the main composition for antipyrotic of the present invention.
EXAMPLE 2
Except that the combustion was executed in an open container, not in a sealed container, 800 g of the carbonized pine cone powder were yielded with the same procedures as Example 1
EXAMPLES 3 and 4
The antipyrotic of the present invention were manufactured by using the carbonized pine cones yielded respectively in Examples 1 and 2, by adding usual carriers to them such that they are each contained in 30% by weight, and by following usual cream formulation methods.
EXAMPLES 5 and 6
Except that 20% by weight of the sesame oil were added, the antipyrotic of the present invention were manufactured with the same procedures as Examples 3 and 4.
Here for the sesame oil, sesame that is solid and contains sesamolin as much as possible is used. The sesame that satisfies such conditions well was that produced at Goesan, ChoongBuk-province, Republic of Korea. The sesame was selected with a selector such that foreign substances were not contained and dried after washing. After complete drying, the sesame was parched at about 160° C. in a parcher immediately before water is completely evaporated and smoke is generated. This parched sesame is crushed with a crusher and oil is extracted for use by pressing with a compressor.
EXAMPLES 7 and 8
Except that 20% by weight of gold and silver powders were added, the antipyrotic of the present invention were manufactured with the same procedures as Examples 3 and 4.
EXAMPLES 9 and 10
Except that 20% by weight of oily material available commercially were added, the antipyrotic of the present invention were manufactured with the same procedures as Examples 3 and 4.
EXAMPLES 11 and 12
Except that 20% by weight of the bark extract of the Amur cork tree were added, the antipyrotic of the present invention were manufactured with the same procedures as Examples 3 and 4.
Here, the bark extract of the Amur cork tree was yielded by extracting at 100° C. for 5 hours and by enriching the solid portion to 15% at about 55° C.

Comparisons 1 and 2
Comparisons 1 and 2 are the case where a patient having the second degree burn as in Example 1 is treated with different antipyrotices.
Comparison 1 used M ointment for general home usage containing beta-sitosterol of cream type from D chemicals, and comparison 2 used Vaseline gauze for general hospital usage. The progresses of the treatment are shown.
Comparisons 1 and 2 were compared using the results of the treatment, without different clinical experiments
The methods were chosen for the following reasons:
Firstly, due to the peculiarity of the clinical experiment for treating burn, it is difficult to separately select patients with the second degree burn.
Secondly, the selecting of animals as the subject of clinical experiment does not allow precise comparison with the subjects of the present invention.
Thirdly, the antipyrotic of comparisons 1 and 2 are used generally at home and in hospital. This makes it possible to compare the progresses of the treatments at several time lapses.
For the reasons mentioned above, Comparisons 1 and 2 are each itemized in Table 2 in the same way as Example 1.
