A 25-year-old woman complaining of dyspnea on exertion, coughing, fever and chills was admitted in January, 1998. Her clinical, radiological, and pathological findings were compatible with hypersensitivity pneumonitis and precipitin antibody to Trichosporon cutaneum was detected in her serum. Although some cases of T. cutaneum-induced hypersensitivity pneumonitis developed during the winter season were reported in Japan, there had been no report of such a case in Korea. This case suggests that T. cutaneum-induced hypersensitivity pneumonitis can develop beyond the summer season in certain environments.

PURPOSE: Varicocele is known as a main cause of primary male infertility and it supposed to be associated with oxidative stress. Anthocyanin is known as a natural plant pigment and novel antioxidant. This study was designed to investigate the effects of anthocyanin on a rat model of varicocele. MATERIALS AND METHODS: Twenty four male rats, induced varicocele by partial obstruction of left renal vein, were divided into four experimental groups: the group induced varicocele for four weeks without anthocyanin, the group received anthocyanin (80 mg/kg) right after varicocele induction, group induced varicocele for eight weeks without anthocyanin, and the group received anthocyanin (80 mg/kg) after four weeks observation following varicocele induction. After anthocyanin treatment, testes from the rats in all groups were removed, weighed, and subjected to histological examination. Apoptosis in the testes was measured by the TUNEL assay. And the oxidative stress was evaluated by measurement of 8-hydroxy-2'-deoxyguanosine (8-OHdG). RESULTS: Induction of varicocele led to decreasing left testis weight, decreasing spermatogenic cell density significantly (p<0.05). Also it led to increasing apoptotic body counts and increasing concentration of 8-OHdG significantly (p<0.05). However administration of anthocyanin right after varicocele induction prevent this change meaningfully (p<0.05). In group received anthocyanin after four weeks observation following varicocele induction, interestingly, there was no significant difference in testis weight, spermatogenic cell density, apoptotic body count and concentration of 8-OHdG compared to group induced varicocele for eight weeks without anthocyanin administration. CONCLUSIONS: These results suggest that anthocyanin is effective in decreasing the oxidative stress of testis in rat induced varicocele and may be effective in making a healthy sperm in patient of varicocele in early stage. However in patient under way in advanced stage, it is supposed that the anthocyanin cannot help having a protective effect from oxidative stress narrowly unless the condition of oxidative stress by varicocele is corrected. Further studies are needed to better understand the mechanisms and actions of anthocyanin and varicocele, and these studies may lead to the clinical application of anthocyanin in preventing male infertility by varicocele.

PURPOSE: To investigate the effects of anthocyanins extracted from black soybean, which have antioxidant activity, on apoptosis in vitro (in hormone refractory prostate cancer cells) and on tumor growth in vivo (in athymic nude mouse xenograft model). MATERIALS AND METHODS: The growth and viability of DU-145 cells treated with anthocyanins were assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and apoptosis was assessed by DNA laddering. Immunoblotting was conducted to evaluate differences in the expressions of p53, Bax, Bcl, androgen receptor (AR), and prostate specific antigen (PSA). To study the inhibitory effects of anthocyanins on tumor growth in vivo, DU-145 tumor xenografts were established in athymic nude mice. The anthocyanin group was treated with daily oral anthocyanin (8 mg/kg) for 14 weeks. After 2 weeks of treatment, DU-145 cells (2x106) were inoculated subcutaneously into the right flank to establish tumor xenografts. Tumor dimensions were measured twice a week using calipers and volumes were calculated. RESULTS: Anthocyanin treatment of DU-145 cells resulted in 1) significant increase in apoptosis in a dose-dependent manner, 2) significant decrease in p53 and Bcl-2 expressions (with increased Bax expression), and 3) significant decrease in PSA and AR expressions. In the xenograft model, anthocyanin treatment significantly inhibit tumor growth. CONCLUSION: This study suggests that anthocyanins from black soybean inhibit the progression of prostate cancer in vitro and in a xenograft model.

PURPOSE: To stratify complications of percutaneous nephrolithotomy (PCNL) in a single, tertiary hospital by use of the modified Clavien system. MATERIALS AND METHODS: From May 1987 to December 2010, 1,236 cases of PCNL were performed at our institute. Medical records were available for 826 cases of PCNL from 698 patients, from February 1995 to December 2010. Using multiple factors, we retrospectively reviewed and analyzed 698 patients for complication rates classified by the modified Clavien grading system, along with success rates. RESULTS: In 698 patients, staghorn stone patients accounted for 33.8% (236 patients). Initial and overall stone-free rates were 69.9% and 88.8%. A total of 297 complications were documented in 282 patients. According to the modified Clavien classification, grade I, II, IIIa, IIIb, IVa, IVb, and V complications were observed in 88 (12.6%), 145 (20.8%), 31 (4.4%), 5 (0.7%), 6 (0.9%), 4 (0.6%), and 3 (0.4%) patients, respectively. Transient peri-nephrostomy catheter urine leakage (15.2%) was the most common complication, followed by transient fever >38degrees (11%) and transfusion (6.9%). Other individual complications occurred in less than 1.5% of cases. In patients with staghorn stones, grade I, II, IIIb, and IVa complications were significantly more common, and all grade IVb and V complications occurred in patients with staghorn stones. CONCLUSIONS: The modified Clavien classification provides a standardized grading system for complications of PCNL, although consensus on specific complications would prompt better comparison between centers. A shorter operation time is imperative to achieve less bleeding. Previous stone-related fever and staghorn stones are significant contributing factors for developing postoperative fever.

PURPOSE: Zinc is one of the trace minerals in the body and is known to have an anticancer effect by inducing apoptosis in prostate cancer. We aimed to investigate the antiproliferative effects of a zinc-citrate compound in bladder cancer. MATERIALS AND METHODS: A bladder cancer cell line (MBT-2) was treated with a zinc-citrate compound at different time intervals and concentrations. Mitochondrial (m)-aconitase activity was determined by use of the aconitase assay. DNA laddering analysis was performed to investigate apoptosis of MBT-2 cells. The molecular mechanism of apoptosis was investigated by Western blot analysis of p53, p21waf1, Bcl-2, Bcl-xL, and Bax and also by caspase-3 activity analysis. RESULTS: Treatment with the zinc-citrate compound resulted in a time- and dose-dependent decrease in cell number of MBT-2 cells. M-aconitase activity was significantly decreased. DNA laddering analysis indicated apoptosis of MBT-2 cells. The zinc-citrate compound increased the expression of p21waf1 and p53 and reduced the expression of Bcl-2 and Bcl-xL proteins but induced expression of Bax protein. The zinc-citrate compound induced apoptosis of MBT-2 cells by activation of the caspase-3 pathway. CONCLUSIONS: We have shown that a zinc-citrate compound induces apoptotic cell death in a bladder cancer cell line, MBT-2, by caspase-3 activation through up-regulation of apoptotic proteins and down-regulation of antiapoptotic proteins.
