Objective: To investigate the application of microemulsion TLC in separation and identification of various effective compositions in traditional Chinese patent medicines. Methods: The various compositions in Kangganmao Granules and Fangfeng Tongsheng Pills were separated and identified simultaneously on polyamide film with six kinds of SDS/n C 4H 9OH/n C 7H 16 /H 2O microemulsions as the mobile phases. Affections of kinds and acidity on separationg results of microemulsions were investigated. Results: The baicalin, chlorogenic acid, Saposhnikovia and glycyrrhiza in Kangganmao Gronules and the emodin, chrysophanol, baicalin, Saposhnikovia and Glycyrrhizae in Fangfeng Tongsheng Pills may be separated and identified simultaneously with microemulsion (containing 75% water) formic acid (9∶1) as mobile phase. Conclusion: Microemulsion TLC is an efficient, simple new method for the separation and identification of various compositions in traditional Chinese patent medicines.

A total of 40 adult black-mice was used and divided into two groups for expeiment. Group A was irradiated by UVB only and Group B had SPF 15 sunscreen a.pplied to the back followed by irradiation by UVB. Each group was divided again into 5 subgroups according to the days of UVB irradiation frcm 2 to 10 days. A Waldmann combination UVA+UVB Radiation Treatment Cabin 8001 was used as the light source and the UVB dosage was 50 mJ/cm2 daily. Skin specimens were taken 24 hours after the last irradiation. Histologic changes in epidermis were reviewed by the light microscope. In group A, the characteristic sunburn cells(SBC) were observed with 100 mJ/ cm2. SBC number was maximum with 400 mJ/cm2. The other epidermal changes were parakerat.osis, crusts, atypical cells, and mitoses of basal cells, which showed graded responses to the UVB doses. Pretreatment with the sunscreen completely prevented these changes.

We report herein a case of eosinophilic pustular follicultis in a 20-year-old man. The patient showed typical clinical picture with specific laboratory and histopathological findings of eosinophilic pustular folliculitis. The patient responded well to systemic administration of corticosteroid and dapsone.

Type V hyperlipoproteinemia result from the accumulation of trglyceride(TG)-rich lipoproteins, very low density lipoprotein(VLDL), and chylomicrons. A 53-year old woman has showed asmptomatic, yellowish patches on tie palms and eyelids and papules on the knees with various types of xanthoma including xanthelasma palpebraum, xanthoma striatum palmare, anrl nonspecific papular xanthoma. The blood chemistry revealed a marked elevation of cholesterol and TG, and lipoprotein electrophoresis showed fasting chylomicronemia, prep-b and b-band, On histologic studies, typical foam cells were shown.

In cholangiographic techniques, the close relationship between choledochal cyst and anomalous union of pancreaticobiliary duct has attracted medical attention. There have been rare cases in which the papilla of Vater was found in a position other than its normal position, and such cases have been reported sporadically. However, such cases are interesting in the anatomical context. In this review, we present our experience of choledochal cyst in a 30-month-old boy in whom the papilla of Vater was positioned in the third portion of the duodenum.

We present herein a case of sebaceous hyperplasia in a 55-year-old male, who showed multiple asymptomatic yellowish papules on the forehead and the cheeks. Histopathologic examination of a papule revealed numerous sebaceous lobules grouped around several enlarged sebaceous ducts. Three weeks of oral administration. of isotretinoin 40 mg per day brought marked improvement.

BACKGROUND: Atopic dermatitis(AD) exibit multiple immune akno malities including elevated serum IgE levels and impaired cell mediated immunity, but basic immunology defect is largely unknown. OBJECTIVE: The purpose of this study was to evaluate the immnologic changes after treatment with Cyclosporin A(CsA) in AD patients. MEHTODS: Eight patients of severe AD were treated with CsA(4mg/kg body weight per day) for 5 weeks, and evaluated clinical and immunological parameters before aid after treatment. RESULTS: Peripheral blood eosinophil counts were significantly decreased after treatment(P<0.05), and serum IgE level was decressed but not significantly. In immediate hypersensitivity reaction by pinprick test, antigen score was.significantly decreased, and in the evaiuation of cell mediated immunity to recall antigens, total induration score was significantly increased(p<0.05). The number of helper T cell and helper/suppressor 7 cell ratio in peripheral blood, and the niimber of helper T and suppressor T cell in skin lesion were both significantly decreased after treatment(P<0.05). Clinical state after treatrnent was good in all of patients. CONCLUSION: The results indicate that CsA act on peripheral blood osinophil and immediate and delayed hypersensitivity reaction as well as helper T-cells in peripheral blood and skin lesion, and it may by useful in the treatrnent of severe AD.
