index (%) in unirradiated mouse skin was 11.0+/-4.3. LI was significantly increased by tape stripping to 22.1+/-4.6. 2. The number of SBC in 1cm epidermis after 50mJ/cm UVB exposure was 28.2+/-4.1. The number of SBC was increased by tape stripping to 57.4+Cell proliferation, by evaluating sunburn cell (SBC) formation, was studied in mouse skin following tape stripping and ultraviolet light B (UVB) exposun.. 1-radiation was achieved using high pressure mercury are UVB. The results are summarized as follows. 1. Labeling 19.2. These results suggest that proliferating cells are more sensitive to UVB exposure.

PURPOSE: The surgical treatment of anal stenosis includes internal sphincterotomy, rotaton flap and advancement flap according to the stenosis degree, recently, Christensen performed house shaped advancement flap and reported fair results. We compared and analyzed the surgical methods and results in patients with moderate and severe anal stenosis who underwent house shaped advancement flap and C-anoplasty. METHODS: We have performed this study with 6 cases using the house shaped advancement flap and 6 cases using the C-anoplasty. The out come was assessed by clinical characteristics, surgical method, operation time, duration of hospitalization, healing time, postoperative complications, results. RESULTS: The average operation time was 38 min in those house shaped advancement flap cases and 63 min in C-anoplasty cases. The average time of hospitalization was 6 days and 9 days, respectively, and the average time of healing was 28 days and 46 days, respectively. In those house advancement flap cases, surgery could be done in 2 directions at the same time in 4 cases and 3 directions in 2 cases; as for those C-anoplasty cases, surgery could be done in 1 direction in 4 cases and 2 directions in 1 case. Two complications were observed in C-anoplasty, one flap infection and one flap necrosis, and in house shaped advancement flap, no complication was observed. CONCLUSIONS: House shaped advancement flap have several advantages compared to the C-anoplasty, and since house shaped advancement flap could be performed in 2 to 3 directions or even 4 directions at the same time, the anus could sufficiently expanded in severe anal stenosis patients. The house shaped advancement flap might be one of the good method in treating anal stenosis.

We carried out the mouse tail technique and the Candida albicans test for the study of the phototoxic reaction to amiodarone. The mouse tail technique is based on the inflammatory response of mouse tails after systemic administration of the drug and UVA irradiation and the Candida albicans test is based on growth inhibition of Candida albicana In the mouse tail technique, following the administration of amiodarone and UVA irradia tion for 5 consecutive days, there was a significant increase(14% ) in the relative water content as compared to other control groups. In the Candida albicans test, UVA irradiation after pretreatment with amiodarone resulted in a clear Candida-free zone around the disc. The results showed that amiodarone had a phototoxic potential and that both of the methods were a good screening test for demonstrat.ing the phototoxicity of a certain drug.

After UV irradiation to mouse epidermis, autoradiography using H-thymidine was performed to study the effects of UV on scheduled and unschcdu ed DNA syntheses. The results can be summarized as follows. l. In case of UVB 100mJ/cm, heavily labeled cells (HLCs) representing scheduled DNA synthesis began to decrease immediately after UVB irradiai,ior and were significantly decreased after 24 hours, but then recovered after 48 hours. The ecovery was maintained from 72 hours, up to 7 days. Sparsely labeled cells (SLCs) repres inting unscheduled DNA synthesis were significantly increased from immediately after UV 3 irradiation and up to 6 hours later. Repair was present at 24 hours, and was maintained at 48 hours, 72 hours, and 7 day after irradiation. 2. In case of UVA, UVA 10J/cm did not affect DNA synthesis sign ficantly. But in cases of UVA 30J/cm and 50J/cm, HLCs began to decrease immediately after UVA irradiation and were significantly decreased for 24 hours. Recovery occured at 48 hours, and was maintained from 72 hours up to 7 days. SLCs were significently increased immediately after and up to 6 hours after UVB irradiation. Repair generally occurred after 24 hours, and was maintained at 48 hours, 72 hours, and 7 days after ir rad ation.

Postoperative (pressure) alopecia is the temporary or permanent loss of hair that occurs following a prolonged immobilization during and/or after general anesthesia and intubation. The cause is considered to be pressure-induced ischemia. Although not an uncommon condition, it is frequently overlooked as a minor complication relative to a causative surgical procedure. We report a 22-year-old woman who was presented with focal hair loss of two weeks' duration after a 9-hour operation for a left brachial plexus injury. Histopathologic examination showed that nearly all terminal follicles were in catagen phase with marked atrophic change of subcutaneous fat.

Aneurysm of the superficial temporal artery is rare. We reviewed seven cases of aneurysm of the superficial temporal artery, which were confirmed surgically and angiographically. The results were as follows: The most common site of aneurysm was left superficial temporal artery, major feeding artery was anterior branch of superficial temporal artery, mean diameter was 7.8mm×12.6mm, and all aneurysms showed lobulated margin with intraluminal filling defects.

Objectives: Endoscopic variceal ligation is well established metbod of treatment for esophageal varices whereas for gastric varices there has not been any systematic report of its use as a method of treatment. To evaluated its possible clinical application, the band ligation(banding) and the method of band ligation in conjuction with submucosal ethanolamine injection(banding with sclero) were tested on canine stomach, and results were assessed.

Erythromelalgia is a rare disease characterized by burning pain of the extremities associated with erythema and increased temperature of the skin. A case of erythromelalgia was reported with review of literatures. It seemed that this is the first reported case in Korean literatures. patient was 12 years old male having erythematous swelling associated with burning pain on his feet and lower legs for five years. Immersion of his feet in warm water quickly, increased the pain but cold water gave prompt relief that he soaked his feet for many hours during the day and night. No specific abnormalities were noticed in Iaboratory studies, Treatment with various topical, systemic medication revealed of unfavorable result.

The appendiceal mucocele is a rare disease and very difficult to get the diagnosis preoperatively because of the rartity of classical symptoms. With progress in diagnostic procedures such as colonofiberscopy, preoperative diagnosis of appendiceal mucocele has become possible. We experienced a case of appendiceal mucocele in 50 years old male who was admitted due to vague RLQ discomfort, and was diagnosed by colonofiberscopy and surgical specimen obtained by right hemicolectomy. So we present this case with a review of literatures.
