PURPOSE: We studied the apoptotic index in prostate cancer tissues and investigated the relationship of apoptosis and clusterin expression. MATERIALS AND METHODS: Forty-two archival prostatectomy specimens of varying grades of prostate cancer and 10 of benign prostatic hyperplasia were subjected to immunohistochemical clusterin staining with anti- clusterin antibody. Staining intensities were classified from 0 to 3. Apoptotic index was calculated with TUNEL positive cells under fluorescence microscope. We performed double staining for clusterin and TUNEL using immunofluorescence technique to determine the relationship between apoptosis and clusterin expression. RESULTS: Immunohistochemistry of clusterin showed a weak intensity in all benign tissues. Clusterin was localized mainly in the epithelial cells. Staining intensity was increased according to Gleason grade of cancer. Apoptotic indices of cancer were 0.86+/-0.8%, 0.76+/-1.0%, 0.39+/-0.4% and 0.14+/-0.09% in grades 2, 3, 4 and 5, respectively. In immunofluorescence localization study, apoptosis was not detected in the cancer cells stained with clusterin. Conversely, clusterin was not expressed in the cells showing apoptosis. CONCLUSIONS: These results more clearly show that clusterin acts as a survival protein protecting from apoptosis in prostate cancer. In addition, our findings revealed that the apoptotic index is lower in high grade prostate cancer. These findings have significant clinical implications for identifying the value of apoptotic index and clusterin expression in prostate cancer. Further study is needed to define the role of clusterin in the development and progression of prostate cancer.

PURPOSE: To investigate the effect of antifreeze protein (AFP) supplementation on ovarian vitrification and transplantation. MATERIALS AND METHODS: In this experimental study, we researched a total of 182 ovaries from 4-week-old ICR mice. The equilibration solution included 20% ethylene glycol (EG), and the vitrification solution included 40% EG, 18% Ficoll, and 0.3 M sucrose. Intact ovaries were first suspended in 1 mL of equilibration solution for 10 min, and then mixed with 0.5 mL of vitrification solution for 5 min. Ovaries were randomly assigned to 3 groups and 0, 5, or 20 mg/mL of type III AFP was added into the vitrification solution (control, AFP5, and AFP20 groups, respectively). The vitrified ovaries were evaluated after warming and 2 weeks after autotransplantation. The main outcome measurements are follicular morphology and apoptosis assessed by histology and the TUNEL assay. RESULTS: A significantly higher intact follicle ratio was shown in the AFP treated groups (control, 28.9%; AFP5, 42.3%; and AFP20, 44.7%). The rate of apoptotic follicles was significantly lower in the AFP treated groups (control, 26.6%; AFP5, 18.7%; and AFP20, 12.6%). After transplantation of the vitrified-warmed ovaries, a significantly higher intact follicle ratio was shown in the AFP20 group. The rate of apoptotic follicles was similar among the groups. CONCLUSION: The results of the present study suggest that supplementing AFP in the vitrification solution has beneficial effects on the survival of ovarian tissue during cryopreservation and transplantation.

Lymphorrhea is a common complication after inguinal dissection for exposure of the femoral artery. Injury of the lymphatics occurs frequently because they are anatomically close to blood vessels. Uncontrolled lymph drainage increases postoperative morbidity, and wound infection may follow. Despite current treatment options, lymphorrhea after inguinal dissection is still difficult to manage and results in a prolonged hospital stay. A vacuum-assisted closure device was used in a 72-year-old woman who had lymphorrhea after vascular surgery by groin incision. Vacuum-assisted control for lymphorrhea resulted in earlier closure of the wound and reduced the length of hospital stay.

BACKGROUND: In the majority of cases, sternal instability and wound infection concomitantly present after a cardiac operation following conventional median sternotomy, and these complications have a major influence on the postoperative course. The aim of this study is to compare the results of the different sternal wiring techniques on sternal infection. MATERIAL AND METHOD: Between April 2004 and December 2008, 157 adult patients underwent cardiac operation through a median sternotomy. 86 patients who had undergone standard peristernal wiring were included in group A, whereas 71 patients who had undergone modified Robicsek sternal wiring were included in group B. The incidences of sternal wound complications in the two groups were assessed. RESULT: The mean age of the group B patients was older than that of the group A patients (61+/-10 years vs 57+/-13 years). The incidence of preoperative left ventricular dysfunction (ejection fraction <30%), chronic obstructive pulmonary disease, renal failure requiring dialysis and diabetes mellitus were significantly higher in Group B, whereas the other perioperative risk factors for infection were not significantly different between the two groups. Two patients in group A experienced superficial wound infection, whereas 4 patients in group B displayed superficial wound infection, but the difference was not statistically significant (p=0.255). Yet poststernotomy deep sternal wound infection appeared in 6 patients of group A, whereas none of the patients in group B displayed this malady. CONCLUSION: The modified Robicsek sternal wiring technique showed greater sternal stability even for the patient with a high risk for infection, and the technique caused a lower incidence of deep sternal wound infection.

Purpose:
Fish allergy is the ninth common food allergy, and cutlassfish is one of the common allergenic fishes in Korean children.However, there is no commercial diagnostic tool for testing cutlassfish allergy in the world. We evaluated the usefulness of serum cod specific IgE (cod-sIgE) to diagnose cutlassfish allergy and cross-reaction between cutlassfish and cod.
Methods:
Nineteen children who experienced immediate type reactions after consumption of cutlassfish were enrolled. Cod-sIgE was measured by ImmunoCAP, and serum samples were obtained from 11 allergic patients and 11 controls. Using our own homemade crude extracts, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), anti-parvalbumin (PV) immunoglobulin G immunoblot, enzyme-linked immunosorbent assay (ELISA), and ELISA inhibition were performed.
Results:
Thirteen patients were clinically allergic to both cutlassfish and cod, and 6 were allergic to cutlassfish alone. The median age and cod-sIgE concentrations were not significantly different between the 2 groups. The clear fish protein bands and PVs were identified on SDS-PAGE and immunoblotting. Serum cod-sIgE was positive in 4 out of 6 cutlassfish mono-allergic patients, however, there was no significant correlation between cod-sIgE by ImmunoCAP and cutlassfish-specific IgE by ELISA. The cutlassfish IgE ELISA was profoundly inhibited by cutlassfish, while the cod IgE ELISA was profoundly inhibited by cod but partially inhibited by cutlassfish.
Conclusion
We found a potential diagnostic value of cod-sIgE to diagnose cutlassfish allergy and the asymmetric cross-reaction between cutlassfish and cod. These results could help diagnose and provide a dietary guidance in cutlassfish allergic children.

Ice easily recrystallizes during warming after vitrification, and antifreeze protein (AFP) can inhibit the re-crystallization. However, no study has evaluated the effect of AFP treatment only thereon during warming. This study sought to compare AFP treatment protocols: a conventional protocol with AFP treatment during vitrification and first-step warming and a new protocol with AFP treatment during the first-step warming only. According to the protocols, 10 mg/mL of LeIBP (a type of AFP) was used. Five-week-old B6D2F1 mouse ovaries were randomly divided into a vitrified-warmed control and two experimental groups, one treated with the conventional AFP treatment protocol (LeIBP-all) and the other with the new AFP treatment protocol (LeIBP-w). For evaluation, ratios of ovarian follicle integrity, apoptosis, and DNA double-strand (DDS) damage/repairing were analyzed. The LeIBP-treated groups showed significantly higher intact follicle ratios than the control, and the results were similar between the LeIBP-treated groups. Apoptotic follicle ratios were significantly lower in both LeIBP-treated groups than the control, and the results were not significantly different between the LeIBP-treated groups. With regard to DDS damage/repairing follicle ratio, significantly lower ratios were recorded in both LeIBP-treated groups, compared to the control, and the results were similar between the LeIBP-treated groups. This study demonstrated that both protocols with LeIBP had a beneficial effect on maintaining follicle integrity and preventing follicle apoptosis and DDS damage. Moreover, the new protocol showed similar results to the conventional protocol. This new protocol could optimize the mouse ovary vitrification-warming procedure using AFP, while minimizing the treatment steps.

PURPOSE: To evaluate correlations between vascular endothelial growth factor (VEGF) which is associated with tissue remodeling and bone repair and systemic and tissue inflammation in osteoarthritis. MATERIALS AND METHODS: Sixty patients who were above grade 2 in Kellgren-Lawrence radiologic classification of osteoarthritis were classified into group 1 (grade 2, 16 patients), group 2 (grade 3, 18 patients) and group 3 (grade 4, 26 patients). All patients were checked C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and total WBC count in the blood and VEGF and total WBC count in the synovial fluid by ELISA. RESULTS: The severe in osteoarthritic change in radiographs, the more VEGF in the synovial fluid (mean value; group 1 82.7 pg/ml, group 2 111.6 pg/ml, group 3 152.6 pg/ml). VEGF in the synovial fluid were related with total WBC count in the blood and in the synovial fluid (p=0.012, p=0.028 respectively), but not related with CRP and ESR in the blood. CONCLUSION: The severe in osteoarthritic change in radiographs, the more VEGF in the synovial fluid. This facts suggested that there were much neovascularization and bone repair in the synovium of advanced osteoarthritis. Therefore further study elucidating mechanisms of tissue remodeling and its associated factors will be needed.
