The purpose of this study were to investigate the changes in serum SGOT, CK and CK-MB levels and the significance of these changes during general anesthesia for open heart surgery. Fourteen patients, who had open heart surgery at Kyungpook National University hospital, were chosen at random their serum SGOT, CK and CK-MB levels were recorded before anesthesia(control group), pre cardiopulmonary bypass, during cardiopulmonary bypass and in the recovery room. The results were as follows: The serum SGOT levels were 21.83+/-4.91 IU/L, 27.20+/-11.83, 34.81+/-16.60 and 72.58+/-37.77, respectively. They very significantly increased (p<0.01) during cardiopulmonary bypass and recovery room compared with pre anesthesia. The serum CK levels were 58.07+/-6.31 IU/L, 91.79+/-44.58, 141.93+/-66.55 and 347.43+/-84.61 respectively. They significantly increased (p<0.05) at pre cardiopulmonary bypass, very significantly increased(p<0.01) during cardiopulmonary hypass and recovery room compared with the preanesthesia. The serum CK-MB levels were 0.00 U/L, 4.54+/-11.80, 14.66+/-17.61 and 80.07+/-34.72 respectively. They very significantly increased(p<0.01) during the cariopulmonary bypass and recovery room.

In this study, we examined arbuscular mycorrhizal fungal (AMF) community structure colonizing field-cultivated ginseng roots according of different ages, such as 1- to 5-year-old plant, collected from Geumsan-gun, Korea. A total of seven AMF species namely, Funnelliformis caledonium, F. moseae, Gigaspora margarita, Paraglomus laccatum, P. occultum, Rhizophagus irregularis, and Scutellospora heterogama were identified from the roots using cloning, PCR-restriction fragment length polymorphism and sequence analysis of the large subunit region in rDNA. AMF species diversity in the ginseng roots decreased with the increase in root age because of the decreased species evenness. In addition, the community structures of AMF in the roots became more uniform. These results suggest that the age of ginseng affects mycorrhizal colonization and its community structure.

PURPOSE: Chemotherapies for breast cancer generally have strong cellular cytotoxicity and severe side effects. Thus, significant emphasis has been placed on combinations of naturally occurring chemopreventive agents. Silibinin is a major bioactive flavonolignan extracted from milk thistle with chemopreventive activity in various organs including the skin, prostate, and breast. However, the mechanism underlying the inhibitory action of silibinin in breast cancer has not been completely elucidated. Therefore, we investigated the effect of silibinin in MCF-7 human breast cancer cells and determined whether silibinin enhances ultraviolet (UV) B-induced apoptosis. METHODS: The effects of silibinin on MCF-7 cell viability were determined using the MTT assay. The effect of silibinin on PARP cleavage, as the hallmark of apoptotic cell death, and p53 protein expression in MCF-7 cells was analyzed using Western blot. The effect of silibinin on UVB-induced apoptosis in MCF-7 cells was analyzed by flow cytometry. RESULTS: A dose- and time-dependent reduction in viability was observed in MCF-7 cells treated with silibinin. Silibinin strongly induced apoptotic cell death in MCF-7 cells, and induction of apoptosis was associated with increased p53 expression. Moreover, silibinin enhanced UVB-induced apoptosis in MCF-7 cells. CONCLUSION: Silibinin induced a loss of cell viability and apoptotic cell death in MCF-7 cells. Furthermore, the combination of silibinin and UVB resulted in an additive effect on apoptosis in MCF-7 cells. These results suggest that silibinin might be an important supplemental agent for treating patients with breast cancer.

OBJECTIVES: The Montgomery-Asberg Depression Rating Scale (MADRS) has been reported as a valid tool for the assessment of depression because it is based on the core symptoms of depression. The aim of this study is to assess the reliability, validity and psychometric properties of the Korean version of the MADRS (K-MADRS). METHODS: One hundred seven patients, including in-patients and out-patients, diagnosed as major depressive disorder according to the DSM-IV criteria were enrolled in this study. They were assessed with K-MADRS, Hamilton Depression Rating Scale (HDRS), Beck Depression Inventory (BDI) and Clinical Global Impression (CGI) to examine cross-validation. Statistical analysis was done using calculation of Cronbach's alpha, Spearman Correlation Coefficient and Principal Components Analysis. RESULTS: The Cronbach's alpha coefficient of K-MADRS was 0.79. And the correlations of each item with total score were statistically significant (r=0.47-0.75, p<0.001). The inter-rater reliabilities of total score (r=0.89, p<0.001) and individual score (r=0.74-0.95, p=0.001) were high. The factor analysis revealed two factors. However, the first one accounted for 39% of variance, while the second one only for 11.1%. The total score of K-MADRS showed a significant correlation with those of HDRS, BDI and CGI (r=0.82, 0.47, 0.74, respectively, p=0.001). CONCLUSION: The K-MADRS showed good reliability and validity for the assessment of severity of depressive symptoms. And it demonstrated similar psychometric properties to previous studies. The K-MADRS is an useful instrument for assessing depressive symptoms in Korea.
