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.

OBJECTIVE: Hysterectomy is one of the most common gynecological operations. The objective of this study is to compare the efficacy of suturing methods of vaginal cuff between laparoscopic and vaginal approach. METHODS: One hundred and sixty one cases of laparoscopic hysterectomy were devided into two groups. In group A(n=67), vaginal cuff was sutured by laparoscopic suture technique and in group B(n=94), vaginal cuff was repaired by vaginal approach. RESULTS: There were no significant differences in uterine weight, hospital stay, pre-and postoperative hemoglobin level and complications including febrile morbidity in two groups. Operation time was significantly shorter in group B(p=0.05). CONCLUSION: Transvaginal repair of vaginal cuff showed shorter duration of operation time than laparoscopic suture technique in total laparoscopichy sterectomy.

We experienced three cases of non-giant congenital nevus. They showed zosteriform or heart-shaped grouping of pigmented papules which were pierced by hairs. Histopathologic examination disclosed nevus cell infiltration in and around hair follicles and in the upper two thirds of reticular dermis. We would like to report these cases as follicle-centered spotted grouped pigmented nevi.

We report an unusual case of sebaceous hyperplasia in an 18-year-old male manifestated clinically as yellowish, grouped papules with a linear distribution, present on the right side of forehead since birth. Histopathologically, a large sebaceous gland composed of numerous lobules grouped around a centrally dilated duct was seen. The sebaceous lobules distributed in the upper dermis showed direct connection to the skin surface, which suggested a transepidermal elimination of sebaceous lobules.

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.

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.

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.
