In the following paragraphs the inventor will describe some biological experiments along with experimental samples and preparation examples as a further illustration for the present invention, but both of them could not be considered as any limitations to the present invention. In addition, if there is no special explanation in the following biological experiments and examples, the percentage "%" indicates "weight %". 1. Anti - inflammatory action 1. Xylene is smeared on the auricle of mice to induce acute inflammation with tumefaction. The mice are treated with 0.5 % tortoise oil, 0.5 % turtle oil and 0.5 % tortoise and turtle oil ( mixture in half and half ) respectively. The auricle tumefaction abates evidently. The rates of abatement of tumefaction show that the tortoise oil, turtle oil and combination of tortoise and turtle oil are 31.4 %, 53.0 % and 71.7% respectively. It means that all of three test samples have an evident anti-inflammatory action. 2. Carrageenin is injected to the hind leg of rat ( plantar fascia ) to induce inflammatory tumefaction on the plantar part. At 30 minutes before inflammation, 0.5 % tortoise oil,0.5 % turtle oil and 0.5 % combination of tortoise and turtle oil are smeared on the local part of planta respectively. All of three test samples have an evident protective action against inflammation. The rate of abatement of tumefaction shows that the tortoise oil, turtle oil and combination of tortoise oil and turtle oil are 40.0 %, 53.5 % and 34 % respectively. The anti-inflammatory action sustains for more than 5 hours. Two above-mentioned experiments prove that 0.5 % tortoise oil, 0.5 % turtle oil and combination of 0.5 % tortoise and turtle oil, i.e., all of three test samples, show an evident anti-inflammatory action sustaining for more than 5 hours. This kind of action may be applied to treat a variety of nonspecific inflammatory reaction of skin and mucosa by means of a local coating method. 2. Anti-itching action Histamine phosphate is injected into the planta pedis of guinea pig to induce itching. Itching threshold is determined, i.e. the threshold concentration which induces plantar itching and causes animals to lick their legs. And then 0.5 % tortoise oil, 0.5 % turtle oil and combination of 0.5 % tortoise and turtle oil are smeared at the planta pedis respectively. The itching threshold (calculated as histamine mg/ml) is determined repeatedly. The experimental results prove that 0.5 % tortoise oil, 0.5 % turtle oil and 0.5% combination of tortoise and turtle oil, i.e., all of three test samples, can obviously enhance the histamine-itching threshold. The rates of enhancement are 138.6 %, 161.3 % and 184.0 % respectively. It is shown that all of them have an evident pruritic action against histamine-induced itching. This function can widely applied to treat a variety of local itching on skin or mucomembrane pruritus ( itching) caused by chemical, physical (light and heat etc.) and environmental factor ( mosquito bite or insect sting ). 3. Protective action against sunlight (ultraviolet ray) radiation Rats of depilated back with an area of 40 cm 2 are irradiated under a 30W UV lamp with a distance of 50 cm for 18 hours successively. The injuries appear as local spotty erythema, flake erythema, edema and desquamation. According to the degree of injury a mark is given to each test sample. The animals are smeared in advance with 0.5 % tortoise oil, 0.5 % turtle oil and 0.5 % combination of tortoise and turtle oil. All of three test samples can evidently reduce the injury by UV radiation. The rates of abatement of injury are 39.30 %, 54.50 % and 69.60 % respectively. The above-mentioned experimental results show that combined tortoise and turtle oil have an evident protective action against UV radiation. It also reflects that the preventive function against sunburn, so can be applied to protect skin from the adverse reaction caused by sunlight radiation. 4. Analgesic action 1. Hot plate method for determining the pain threshold of mice. The planta of mice is smeared in advance with 0.5 % tortoise oil, 0.5 % turtle oil and 0.5 % combination of tortoise oil and turtle oil respectively. The pain threshold of mice is determined. All of three test samples can enhance the pain threshold. The rates of enhancement are 48.8 %, 175.3 % and 112.9 % respectively. The experimental results prove that all of three test samples have anagesic action. 2. Algogenic method with hot water (55 °C) for observing the analgesic effect. Mice tail is soaked in hot water. The latent period of tail retraction is defined as pain threshold. 0.5 % tortoise oil, 0.5 % turtle oil and 0.5 % combination of tortoise oil and turtle oil are smeared on the mice tail respectively. Time of tail retraction is determined. All of three test samples can prolong the tail retraction time, i.e. evident enhancement of pain threshold. The rates of enhancement are 46.4 %, 132.2 % and 282.2 % respectively. The above-mentioned experiments prove that tortoise oil, turtle oil and the combined tortoise oil and turtle oil have analgesic action. The action of turtle oil is stronger than that of tortoise oil. The action of the combined tortoise oil and turtle oil is stronger than that of the single one. This fact has provided a scientific basis for that tortoise oil, turtle oil and combined tortoise oil and turtle oil can be used as an analgesic for treating local wound and ulcer. 5. Promotive action on proliferation of human fibroblast The culture of human, fibroblast in vitro by adding tortoise oil, turtle oil and combined tortoise oil and turtle oil is promoted. It is found that the cells proliferate quickly and the number of cell increases nearly by times. The concentration of tortoise oil and/ or turtle oil for cell proliferation is 3.125 ∼ 6.25 µg/ml. When the concentration arrives at 12.5 µg/ml, the value of cell proliferation is the biggest. The photos are being analyzed in order to make clear the reaction link for promoting the cell proliferation. So far as medical use is concerned, it is advantageous to promote wound healing; as cosmetic use, to promote metabolism and proliferation of epidermic cells and to prevent skin from senility. 6. Distinct therapeutic effect on second - degree scald on rat A model of second - degree scald by hot water is made on rat at 100 % area of body surface. And then 0.5 % tortoise oil, 0.5 % turtle oil and 0.5 % combination of tortoise and turtle oil are smeared respectively on the local scalding part for once 8 hours for 20 days in all. According as healing rate of surface of wound and rate of decrustation, the therapeutic effects are assessed. The results are as follows: Influence on Decrustation Rate Decrustation rates (%)(x± s) Groups 10 days after scalding 15 days 20 days Control 8.0±3.5 30.2±6.7 58.0±12.7 Tortoise oil 31.6±8.3 84.0±6.8 91.5±7.1 Turtle oil 8.1±1.7 65.0±12.0 85.0±10.0 Combination of Tortoise and Turtle oil 34.4±7.0 88.1±8.1 96.8±5.0 Influrence on Rate of Healing on Surface of Wound Rate of healing on surface of wound (%)(x±s) Group 10 days after scalding 15 days 20 days Control 6.1±3.3 23.4±5.1 53.6±11.8 Tortoise oil 29.4±16.2 74.8±11.9 89.0±16.9 Turtle oil 5.8±2.4 55.0±12.9 80.8±13.6 Composition of 31.0±12.6 76.6±10.0 95.0±2.7 Tortoise oil and Turtle oil Comparison with samples of surface of wound through pathologic sections is carried out. The experimental results prove that tortoise oil, turtle oil and combined tortoise oil and turtle oil, after being smeared on rat of second - degree scald, have an evident promotive effect on decrustation, decreasing local inflammation, promoting restoration and proliferation of epithelia, accelerating healing of surface of wound and obviously decreasing formation of scar. These therapeutic actions provide an experimental basis for that the tortoise oil, turtle oil and combined tortoise oil and turtle oil can be applied to the treatment of burn and scald. 7. Therapeutic action on psoriasis According to the publicated literature, 50 % Punarol is smeared on guinea pig's skin of auricle once a day. A typical histological lesion which is similar to human psoriasis forms after 3 weeks, followed by incomplete cellular keratinization in horny layer, distinct pigmentation, distinctly thick epiderm, increasing dermal papilla, rugged basilar membrane, transforming into prickle - cell layer mainly, karyopyknosis and necrosis of partial cells as well as leukocytic infiltration between cells. After smearing 0.5 % tortoise oil, 0.5 % turtle oil and 0.5 % combination of tortiose oil and turtle oil on test animals for the treatment, the typical pathologic changes of psoriasis are evidently improved by these oil after 2 weeks. Epithelial keratinization is complete. Thickness of epithelial prickle-cell layer approaches a normal state. Leukocytic infiltration is decreased and its formation approaches a normal state.
