PURPOSE: In adriamycin(ADR)-induced cardiomyopathy, several different mechanisms are suggested. However, little information is available regarding the role of apoptosis. In the present study, we examined the induction of apoptosis on ADR treatment and anti-apoptotic effects of probucol, a lipid-lowering drug, and we also studied the changes of bcl-2 expression in order to see the molecular mechanisms underlying the effect of probucol. METHODS: Cardiac myocytes were isolated from 3-day-old rats, and cultured in low(1 pM) or high doses(10pM) of ADR for 24 hours. Probucol(50 pM) was added 30 minutes before ADR administration. Apoptosis was determined by TUNEL staining, and bcl-2 expression was estimated by immunocytochemistry. RESULTS: The number of TUNEL-positive cells significantly increased in both groups treated with ADR. However, anti-apoptotic effect of probucol was evident only in low dose. In addition, the expression of bcl-2 was significantly increased only in the low-dose ADR treatment group and its expression was inhibited by pretreatment of probucol. CONCLUSION: These results suggest that apoptosis might play an important role in ADR-induced cardiotoxicity, and ADR-induced apoptosis was partially prevented by pretreatment of probucol. And ADR-induced apoptosis was not related with depression of bcl-2. Additionally, inhibition of bcl-2 gene expression of low-dose ADR treatment group by probucol suggests that another cell survival mechanism could be implicated in the action of probucol.

BACKGROUND: The size of the baseplate used in reverse total shoulder arthroplasty (RTSA) tends to be larger than the average size of the glenoid in the Korean population. The mismatch between the sizes of the baseplate and the patient's glenoid may result in improper fixation of the glenoid baseplate. This in turn may lead to the premature loosening of the glenoid component. Thus, we evaluated the short-term results of using a 25-mm baseplate in RTSA. METHODS: Seventeen patients with cuff tear arthropathy underwent RTSA with a 25-mm baseplate. The mean age of the patients was 70.1 years, and the mean follow-up period was 14.0 months. We evaluated clinical outcomes preoperatively and postoperatively: the range of shoulder motion, the American Shoulder and Elbow Surgeons (ASES) score, and the Korean Shoulder Society (KSS) score. RESULTS: We found that the mean ASES score and KSS improved from 35.0 to 74.4 (p<0.001) and from 46.9 to 71.8 (p<0.001) with RTSA. The mean forward elevation and abduction, external rotation also improved from 78.6degrees to 134.3degrees (p<0.05) and from 66.6degrees to 125.0degrees (p<0.05), from 20.2degrees to 28.4degrees (p=0.43). Postoperative complications were seen in 12% of patients, but neither the loosening of the glenoid baseplate nor inferior scapular notching were observed. CONCLUSION: In sum, the results of using a 25-mm baseplate in RTSA were similar to those of previous reports. Even though the outcomes are those of a short-term follow-up, neither the loosening of the glenoid baseplate nor the scapular notching were observed.

This case report draws attention to the possibility of symptomatic and asymptomatic intraarticular ganglion cyst which was situated adjacent to the insertion sites of the anterior or posterior cruciate ligament. In many reports and our case, MR imaging is recommended as the modality of choice in diagnosing method and the cyst, if encountered, is successfully treated with arthroscopie technique. We report one case of symptematic ganglion cyst of the posterior cruciate ligament with review of literatures.

Cognitive deficit is frequently observed in patients with schizophrenia. It is significantly associated with functional outcome. In the past 20 years, due to significant advances on the concept of schizophrenia, cognitive deficit has been accepted as a core feature. In the DSM-5, cognitive deficit does not introduce diagnostic criteria of schizophrenia, but did one dimension of diagnosis of psychosis. Existing schizophrenia drugs are effective in treatment of positive symptoms of schizophrenia, but lack of effectiveness on improving cognitive function. Led by NIMH (National Institute of Mental Health), the MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophrenia) meeting was conducted in order to achieve consensus on measuring tools and neuropharmacological targets for clinical trials for development of new drugs for improvement of cognitive function in schizophrenia. At the MATRICS consensus meeting, glutamatergic modulators and nicotinic and muscarinic agonists are expected to be promising, but should be proven by a double-blind placebo-controlled multicenter study for patients.

PURPOSE: Carcinoembryonic antigen (CEA) is the most widely used tumor marker for detecting colorectal cancer. This study was designed to evaluate the level of serum CEA that is associated with recurrence after potentially curative surgery for colorectal cancer. METHODS: We retrospectively investigated the pre- and post-operative levels of serum CEA in 246 patients with colorectal cancer and they had undergone potentially curative surgery from 1996 through 2005. RESULTS: The pre-operative CEA level was significantly associated with the number of metastatic lymph nodes, the tumor size and the recurrence rate. The feature that was associated with recurrent disease on multivariate analysis was the pre-operative level of serum CEA. CONCLUSION: In order to detect the recurrence of colorectal cancer, we should closely follow up with frequent checks of the CEA level after surgery for those patients who had a high preoperative CEA level.

Glutathione S-Tanaferase (GST) is tripeptide, which plays a central role in the detoxification of electrophilic xenobioticas, including cytotoxic drugs and carcinogens, by conjugation with redueed glutathione. There are four major claases af human GST : pi, alpha, mu and rnicrosomal, They are propoaed as a marker for human and experimental neoplasia iincluding liver, kidney, lung,colon, uterine cervix, etc. Expression of pi, alphn, mu form of GST in control (15 cases), CIN (14 cases), invasive carcinoma (28 cases) of human uterine cervix was investigated immunohistochemically. They were selected fram September, 1992, to,June, 1992, in the department of Obstetrics and Gynecology, Yonsei university College of medicine. In nucleus, the expresaion of GST pi was increased statistically significant in case of CIN and invasive Ca. of Cx. compared to control(p=0.018, p=0.002). But expression of GST alpha, mu has no significant difference in each case. In cytoplasms, the expvession of GST pi was increased statistically significani, in case of CIN and invasive Ca. of Cx. (p=0.001, p<0.001). But expreasion of GST alpha, mu has no significant differenrce in each case. There was no statistically significant diHerence in expression of GST isoenzymes oC each nucleua and cytoplasm according to stage and cell type in Ca. oC Cx.

BACKGROUND: This study was done to identify factors that influence the willingness to be vaccinated with the human papilloma virus (HPV) vaccine in female college students eligible for a catch-up vaccination program. METHODS: This cross-sectional study included 572 female students aged 18-26 years attending one selected university in the Gyeongbuk Province. From March 2 to 6, 2009, they completed a self-administered questionnaire on their HPV vaccination status. Thereafter, unvaccinated participants were educated about the vaccination program, and each participant's willingness to be vaccinated was assessed. RESULTS: Of the 572 participants, 18 (3.1%) were already vaccinated with the HPV vaccine. The number of participants advised to be vaccinated was 102 (17.8%). Of the 554 unvaccinated participants, 305 (55.1%) were willing to be vaccinated after being educated about the vaccination program. Of the remaining 249 unvaccinated participants, 116 (48.7%) refused the vaccine due to its high cost. Advice by family members was related significantly to the willingness to be vaccinated (odds ratio, 2.37; 95% confidence interval, 1.09-5.14). CONCLUSIONS: The results of this study suggest that the willingness to be vaccinated with the HPV vaccine could be increased in female college students if they are advised to do so by their family members after being educated about the vaccination program.
