Glutathione S-transferase (28GST) with molecular mass of 28 kDa is an antioxidant enzyme abundant in Clonorchis sinensis. In adult C. sinensis, 28GST was localized in tegumental syncytium, cytons, parenchyma, and sperm tails examined by immunoelectron microscopy. C. sinensis 28GST was earlier found to neutralize bioreactive compounds and to be rich in eggs. Accordingly, it is suggested that 28GST plays important roles in phase II defense system and physiological roles in worm fecundity of C. sinensis.

Using atomic absorption spectrometry Pb, Cd, Cu, Zn and Fe were measured in sweat and Pb, Cd, Cu and Zn, in blood. The subjects were 22 healthy males, aged between 23-44. Sweating was induced with an environmental room (1 hour at 46C dry bulb and 36C wet bulb). Sweat samples were obtained from the left arm by the armbag technique. The sweat volume was 23.3+7.3ml(n= 22). The concentrations, in ug/ml, of trace elements in sweat were : lead, 0.18+0.17(n=22); cadmium, 0.006+0.006(n=22); copper, 0.37+0.66(n=10); zinc, 0.63+0.5(n=10); and iron, 0.22+0.12(n=10). The concentrations, in ug/ml, of trace elements in blood were : lead, 0.28+0.15(n=20); cadmium, 0.005+0.007 (n=20); copper,0.69+0.22(n=20); and zinc,5.61+0.86(n=20). These results clearly showed the significance of sweating as a route of excretion of trace element.

PURPOSE: recent studies have reported that the expression of Drg-1 is up-regulated by androgen. It has been suggested that Drg-1 gene be used as a molecular marker for prostate cancer therapies like PSA. To de termine the role of Drg-1 gene as a molecular marker during intermittent androgen deprivation(IAD) therapy, we investigated the expression of Drg-1 and compared it with PSA expression in human prostate cancer cell lines treated with dihydrotestosterone (DHT) continuously or intermittently. MATERIALS AND METHODS: Two prostate cancer cells having different status of androgen receptor [LNCaP (androgen dependent) and PC-3 (androgen independent)] were used in this study. To know the change in PSA and Drg-1 expression after DHT treatment the cells were cultured in steroid-free RPMI media for 24 hours. 10(-7) and 10(-8)M of DHT and 10(-7)M bicalutimide was added into the cells and then cultured for 72 hours. And we established in vitro IAD model using LNCaP cells. Northern analyses were performed to determine the expression level of both PSA and Drg-1genes. Also, western analyses were performed to determine the protein level of proliferating cellular nuclear antigen and androgen receptor. RESULTS: Transcripts of Drg-1 were detected in both LNCaP and PC-3 cells but PSA was not expressed in PC-3 cells. The expression of Drg-1gene in LNCaP cells was up-regulated by 10(-8)M of DHT like PSA gene and down-regulated by 10(-7)M bicalutamide. In the treatment of intermittent androgen deprivation, the expression pattern of Drg-1was similar to that of PSA. However, up-regulation of PSA was detected earlier than of Drg-1. CONCLUSIONS: Based on observation, Drg-1 was up-regulated by androgen and down-regulated by anti-androgen. This suggests that Drg-1gene is useful for determining the androgen independency of prostate cancer during IAD.

A perplexing developmental error is 46,XX congenital absence of vagina ( Mayer-Rokitan-sky-Kster-Hauser syndrome, Mullerian dysgenesis, vaginal aplasia ). The Mayer-Rokitansky-Kster-Hauser syndrome refers to the climical entity consisting of primary amenorrhea associated with congenital absence of the vagina, 46,XX karyototype, a rudimentary uterus or complete absense, normal overian function and normal ovulation, normal female breast development, body proprotion and body hair, frequent association of renal, skeletal and other cpngenital anomalies. This syndrome results from agenesis of both Mllerian ducts or from a failure of the Mllerian ducts to estavlish a proper communication with that part of the vagina from the urogenital sinus. A case of mayer-Rokitansky-Kster-Hauser syndrom was reviewed briefly.

We present an unusual case of 31 year old lady with a longitudinal tear of flexor hallucis longus(FHL) caused by trauma. Tendonitis of the FHL, well known as dancers tendonitis, can be characterized by triggering of the great toe. As the foot is brought into plantar flexion with a forcible active contraction of the FHL, a snap is noted in the region of the posteromedial aspect of the ankle. Magnetic resonance imaging may be helpful in establishing diagnosis. The patient has obtained longterm satisfactory relief of her symptoms with surgical treatment. The literature on tendonitis of the FHL is reviewed with a reported case.

Local deposition of antibiotics has become increasing popular in the management of open fractures or osteomyelitis, and several substances have been employed as the vehicle for delivery. Although the elution characteristics of some substances have been documented, a comparative study of the characteristics of the commonly used substances were performed in order to establish the clinical indications for particular vehicles. Carriers were prepared, which were human iliac cancellous bone, bovine cancellous bone matrix(Lubboc?), absorbable gelatin sponge(Gelfoam?), fibrin glue(Beriplast? P) and polymethylmethacrylate(CMW?) for elution characteristics of vancomycin. The each carriers were immersed on the 20 ml of PBS and then obtained the samples for analysis of concentration of vancomycin at first, second, third, fourth, fifth, sixth, fourteenth, twenty-first, twenty-eighth day after immersion. The assay technique was fluorescent polarization immunoassay(Abbott, Dallas, Texas, U.S.A.). Nearly 50% of vancomycin was released from human iliac cancellous bone, Lubboc? and fibrin glue during the first 3 days, and negligible after first week. Gelatin sponge produced high local concentration of vancomycin during the first week. PMMA eluted the only 6% of vancomycin during the first day and trace amount detected as long as 4 weeks. There are significant statistical difference among carriers at second and fourth week(ANOVA test, P < 0.05). The authors considered that human iliac cancellous bone, Lubboc? ,Gelfoam? and fibrin glue may be best employed when brief antibiotic coverage is required, whereas PMMA may be better suited for long-term coverage.

Thrombosis of one or both renal veins occurs in a variety of settings such as trauma, dehydration, extrinsic compression, nephrotic syndrome, pregnancy, oral contraceptives or invasion by tumor. Nephrotic syndrome and certain carcinomas seem to predispose to the development of renal vein thrombosis. The most common carcinoma which is associated with renal vein thrombosis is the renal cell carcinoma. But, renal vein thrombosis associated with tumor other than renal cell carcinoma is extremely rare. Our patient was diagnosed as lung and uterine cervical cancer by histologic examination. The patient complained of left flank pain. Abdominal CT scan shows the dilated left renal vein filled with hypodense material and parenchymal infarction on the left kidney. Renal arteriography shows cut-off sign on a branch of the left renal artery. Inferior venacavography revealed contrast-filling defect in the left renal vein. To our knowledge, renal vein thrombosis with lung and uterine cervical carcinoma is the first report in English literature. So, we have presented a rare case of a renal vein thrombosis in a patient with lung and uterine cervical cancer.

BACKGROUND: Microlymphocytotoxicity test is most widely used for HLA Class l typing but almost all laboratories depend on imported HLA Class 1 typing trays. Matching criteria for the selection of HLA- matched platelets to treat platelet refractoriness is not as strict as for bone marrow transplantation. Therefore, with the acquisition of various antisera against high frequency HLA antigens, self-made HLA typing trays can be used for HLA typing of HLA-matched platelet donors. METHODS: 140 samples obtained during placental delivery were tested for the presence of HLA antibodies against a well-characterized panel of 90 cells. Specificity of HLA antisera were determined by evaluating the correlation coefficient r of the 2 x 2 table, x2 test. Antisera strength was evaluated by the strength index. RESULTS: HLA antibodies were detected in 25 samples by primary screening and 23 samples also showed a positive reaction in secondary screening(16%). Among 23 samples, 1 1 antisera were of reagent grade quality and 7 were monospecific antisera. DISCUSSION: Imported HLA typing trays can be replaced by harvesting HLA antisera against HLA antigens which are relatively common in Koreans through continuous HLA antibody screening using gushed out blood during placental delivery.
