Background: If phototoxic:ity can be predetermined in vitro, the information will aid in prognosticating whether or not caimpounds have a photosensitizing pczrlial. OBJECTIVE: For the evaluation of the phototoxic potentials of reral drugs, we performed the Candida albicans test and the photohemolysis test. METHODS: The Candida altiicans test is based on growth inhibtion of Candida albicans after application of the drug and ultraviolet light A( UVA ) irradiatior and the photohemolysis test is based on hemolysis of red blood cells caused by irradiation ir the presence of photosensitizing compounds. In the Candida albicans test, clear zones around the drug patches were evaluated, which means positive results for the phototoxic potential of the drugs. In the photohemolysis test, the amounts of hemolysis were evaluated by measuring the relar absorbance at 540nm using a spectrophotometer. RESULTS: In the Candida albicans test, ibuprofen, naldix acid, chlorpromazine and thiodiphenylamine showed positive results, whereas others did not the photohemolysis test, griseofulvin, ibuprofen and nalicdixic acid showed increased amounts hemolysis at UVA and ultraviolet light B(UVB) irracliation, and chlorpromazine, thiodiphenylaiair, chlorothiazide and piroxicam showed increased amounts of hemolysis at UVA irradiation only. CONCLUSION: The results showed that both methods were goodness screening tests for demonstrating the phototoxicity of therapeutic drugs.

The potential acuity meter(PAM) has been reported to be a useful instrument for predicting postoperative visual acuity after cataract extraction surgery. Forty nine eyes were tested with PAM before surgery, and the best postopertive visual acuity was obtained. The PAM accurately predicted the postoperative visual acuity to within three lines in 90.0% of the cases. When the test is in error, the tendency is for the PAM to underestimate the final acuity rather than to overestimate. Especially under undilated pupil, in dense cataracts (<20/200),and,in posterior subcapsular and cortical cataracts, the PAM tends to underestimate further.

PURPOSE: A pancreaticoduodenectomy is the procedure of choice for patients with resectable carci nomas of the pancreatic head, duodenum, or periampullary region. Although the morbity and the mortality are decreasing now, but there are still high. Leakage of the pancreatic duct remains the major source of death and complications after a pancreaticoduodenectomy. Thus, the authors used a stented pancrea ticojejunostomy and jejunojejunostomy after a pancreaticoduodenectomy to decrease leakage of the pancreatic duct. METHODS: The authors studied retrospectively 44 consecutive patients who had a pancrea ticoduodenectomy with a stented pancreaticojejunostomy and jejunojejunostomy at Kwangju Christian Hospital between 1993 and 1998. RESULTS: Leakage of the pancreaticojejunostomy was diagnosed in one of the 44 patients (2.5%). There were two deaths after the pancreaticoduodenectomy, one from compli cation of leakage of the pancreaticojejunostomy and the other from UGI bleeding. CONCLUSION: The stented pancreaticojejunostomy and jejunojejunostomy is an effective and safe method for use with a pancreaticoduodenectomy. However, the leakage that might occur despite the stented pancreaticojeju nostomy and jejunojejunostomy can be managed less invasively.

Clear cell sarcoma of tendon and aponeurosis is a rare malignant tumor. It occurs chiefly in young adults, predominates in women and is most common in the regions of the foot and ankle. We report a case of clear cell sarcoma of tendon and aponeurosis in s 22-year-old man. he pstient had had a asymptomatic, normal skin colored, relativerly hard, dome shsped nodule on the anterior chest for 6 months. Histopsthologic findings revealed uniform pattern composed of compact nests of round or fusiform cells which had clear cytoplasm and were surrounded by delicate framework of fibrocollagenous tissue, and the individual tumor cell had a fairly regular appearance of possessing round to avoid vesicular nucleus with prominent basophilic nucleolus. One year after surgical excision and post operative radiotherapy, there was no recurrence.

BACKGROUND: renal artery stenosis (RAS) is a major cause of renovascular hypertension and renal function due to ischemic atrophy of kidney. There are several methods to treat the RAS, including are surgery, percutaneous transluminal renal angioplasty, and medical treatment. The purpose of this study is to evaluate the usefulness, safety, and efficacy of percutaneous transluminal stent deployment in RAS. METHOD: From January 1995 to July 1996, 17 patients underwent renal stent implantation due to renal artery stenosis (11 male, 6 female). the mean age was 49 years old, one patient had both renal artery stenosis and total lesions were 18. The causes of renal artery stenosis were atherosclerosis in 12, fibromuscular dysplasia in 2, Takayasu's disease in 2, and autoimmune disease (Bechet's) in one case. Renal artery stenting was performed via femoral artery in 12 lesions and brachial artery in 6 lesions. Follow up was performed by renogram, renal angiogram, and clinical examination. RESULT: the degree of renal artery stenosis was 83% (70-95%). the lesion sites were 12 ostial and 6 non-ostial lesions. The used renal stents were Palmaz-biliary stent in 17 lesions and Micro-2 stent in one lesions. All stents were implanted successfully and there was no residual stenosis in all patients except one case showed 20% residual stenosis due to huge renal artery size. The transstenotic pressure gradients after renal artery stenting was decreased markedly from 74mmHg to 2mmHg. There no serious complications such as a death, emergency surgery, or nephrectomy. There were two minor complications which were one case of pyelonephritis and one case of inguinal hematoma. After stenting, blood pressure was decreased partially in 13 patients and completely in 2 cases. CONCLUSION: Renal artery stenting appears to be safe and feasible and the alternative treatment modality to surgery for renal artery stenosis.
