Peanut is one of the most popular foods in the world due to its high nutrition; however, it contains multiple seed storage proteins which are identified as allergens and hence are the most common cause of life-threatening, IgE-mediated anaphylaxis among the hypersensitive individuals. Three peanut proteins, Arachis hypogaea allergy 1, 2, 3 (Ara h 1, Ara h 2 and Ara h 3), which have the common biochemical characteristics like resistance to proteases and heat, are considered as the major allergens because they are recognized by serum IgE from a peanut-allergic patient population. The linear IgE-binding epitopes in the allergens lay the foundation of the anaphylaxis in the peanut-allergic individuals. Peanut allergy is often a life-long problem, so many investigators are focusing on decreasing clinical reactivity. In this review, the latest advances in the researches on biochemical characteristics, structure and function of the three major allergens were described and particular attention was given to the immunity properties of the three allergens. The future research directions were also discussed.

The present study aimed to evaluate the anti-diabetic property of peanut shell polyphenol extracts (PSPEs). Diabetic rats were oral-administrated with PSPE at doses of 50, 100, and 200 mg/kg body weight (BW) per day for 28 consecutive days, with metformin (Met) as a positive control. The results showed that, similar to the Met treatment, administration of PSPE caused significant decreases in food intake, water intake, fasting blood glucose, total cholesterol, triglyceride, low-density lipoprotein cholesterol, and methane dicarboxylic aldehyde in serum, and significant increases in BW, insulin level, high-density lipoprotein cholesterol, superoxide dismutase, glutathione, and liver glycogen. Further, glucose tolerance was markedly improved in the PSPE-treated diabetic groups. Histopathological results showed that PSPE improved cellular structural and pathological changes in liver, kidney, and pancreatic islets. Collectively, the results indicated that the hypoglycemic effects of PSPE on high-fat diet/streptozotocin (HFD/STZ)-induced diabetes are comparable to Met, though their exact mechanism actions are still under investigation. Therefore, the current study suggests that PSPE could be a potential health-care food supplement in the management of diabetes.

During the last three years, from 1967 to 1970, three hundred and three cases of psoriasis were treated by Goeckrman's regimen and oral methotrexate, 270 cases and 33 cases respectively. Authors evaluated the clinical effectivness and side effect of methotrexate and it compared with the result of Goeckermans method and review about the articles. Of the 303 psoriatics, 140 were male(44%) and 163 were female(55.6%). The majority of the primary manifestation appeared in 16 to 30 year .age group with maximal occurence in the 16 year to 20 year age group (53 cases), but 33 cases were noted below the 10 years old age(Fig.2). The duration of the disease in most cases was 1 to 10 years,but the highest number, in 72 cases, was 1 to 5 years group(Fig 3 A, 3 B). 40 cases was in below 6 months. The methotrexate were administered orally, 2. 5 mg. tab., twice daily(5 mg) for 5 to 7 days, followed by 3 to 5 days resting in accordance with the, patient's condittion. The Goeckerman regirnen of 2% coal tar and 2% salicylic acid in vaselin applied to whole skin lesions in the night and the excess tar was removed frorn skin by gentle wiping with a gauze pat, saturated with Arachis oil, in the next morning, follawed by ultra-violet ray irradiation for 30 second at first day, then the dose increased 30 second daily to reach 5 min. After the ultra-violet irradiation bath was done, and one hour later 2% coal tar and 2% salicylic acid vaselin were applied again. These schedules were repeated 2 to 3 courses (20 to 30 days) in mast cases. In occasion of Goeckerman treatment, among the completely cleared 93 cases during the preveous treatment, the most cases were recurred within 3 to 12 months but 16 cases within 1 month. In occasion of methotrexate, the lesions recurred within 6 months to 2 years in 17 cases of the 33 cases, but 3 cases were within one month after completely cured preveously. The starting of remission, in Goeckerman methods, was noted within 7 to 14 days in most cases(13 cases), and in 3 cases it started within 3 to 4 days. And the completely clearing of the lesions noted within 20 to 25 days in most cases(16 to 21 cases). The starting of remission, in methotrexate treatment of 33 cases, was occurred within 1 to 2 weeks in most cases(27 cases), and completely clearing of lesions noticed within 14 ta 20 days in 28 cases. But in 2 cases it needed only 7 days to make completely clearing the skin lesions. The side effects of the Goeckerman's method were as follow : 1) Contact dermatitis due to tar hypersensitivity in 3 cases. 2) Mild local burn due to over dose irradiation of ultra-violet ray in 5 eases, otherwise no appreciable side effects were noted. The side effecst of methotrexate were noted in 17 cases among the 33 cases. 1) Aphtous ulcer in 4 cases, 2) Peptic ulcer in one case, 3) Tinitus in one case, 4) Other side effects such as dizziness, loss of appetite, headache, fatiguability were notable in 10 cases. 5) In addition to above mentioned sidle effects the blood chemistry include L.P.T., wbc count, platelet count, ESR, Hgb, and creatinine showed as follow before and after administration of methotrexate. a) The white blood cells, platelet count were tend to decrease after the administration of methotrexate than before one. b) Among 33 cases the SGPT levels were checked in 16 cases, and in most cases it raised more and less than before the administration of methotrexate, but only 8 cases were ahove the normal ranges(35 units). The SGOT level also raised after one course, but only 8 cases were above normal ranges(40 units). c) Hgb, ESR, creatinine showed no remarkable changes. In many references the effects and side effects of methotrexate were discussed, but their view were not uniform and variable. In the clinical improvement, recurrency, and side effects, the large single weekly dose of methotrexate had no fundamental differences compare with the author's small daily doses. We agree with the Ryan's report(11), in which the large single dose were not always safer and more effective than the small dose. Still there are many important problems to study about the dosage, interval of administration, and resting period in the treatment of psoriasis with methotrexate.
