The present study elucidated the effects of indoleamines (serotonin, melatonin, and tryptophan) on oxidative damage of brain mitochondria and synaptosomes induced either by 6-hydroxydopamine (6-OHDA) or by iron plus ascorbate and on viability loss in dopamine-treated PC12 cells. Serotonin (1-100 microM), melatonin (100 microM), and antioxidant enzymes(More)
Prevalence survey of neurocysticercosis was made in a mixed epilepsy patients of Changmi Club in Korea. From February 1987 to July 1990, a total of 2,667 randomly selected patients at 27 local centers was tested for their serum levels of anti-Cysticercus antibody (IgG) by enzyme-linked immunosorbent assay. Positive rate of the antibody was 4.0% in the(More)
TWO VARIANTS OF THE INOSINE TRIPHOSPHATASE (ITPA rs1127354, rs7270101) gene cause ITPA deficiency and protect against the hemolytic toxicity of ribavirin. We investigated the clinical significance of ITPA variants in Korean patients treated with pegylated interferon (PEG-IFN) plus ribavirin. Of the 133 patients, 108 were CC and 25 were non-CC at rs1127354(More)
To evaluate the activity and safety of a combination chemotherapy with epirubicin, cisplatin, and a protracted venous infusion of 5-fluorouracil (ECF) in unresectable or metastatic gastric cancer, a phase II study was performed. Thirty-five chemotherapy-naive patients were given ECF. Epirubicin (50 mg/m(2) intravenous, i.v.) and cisplatin (60 mg/m(2) i.v.)(More)
The dermal papilla cells (DPCs) of hair follicles are known to secrete paracrine factors for follicular cells. Shotgun proteomic analysis was performed to compare the expression profiles of the secretomes of human DPCs and dermal fibroblasts (DFs). In this study, the proteins secreted by DPCs and matched DFs were analyzed by 1DE/LTQ FTICR MS/MS,(More)
Glucocorticoid (GC) is synthesized mostly in the adrenal gland and is secreted in response to stressful conditions. The stress-induced increase in systemic GC may mediate diverse types of cellular damage. However, the specific effects of GC on the dermal papilla cells (DPCs) of hair follicles remain unknown, although stress-related hair loss has increased(More)

Terahertz (THz) technology has emerged for biomedical applications such as scanning, molecular spectroscopy, and medical imaging. Although a thorough assessment to predict potential concerns has to precede before practical utilization of THz source, the biological effect of THz radiation is not yet fully understood with scant related investigations. Here,(More)
BACKGROUND/AIMS Sustained virologic response (SVR) for the treatment of chronic hepatitis C (CHC) may differ with ethnicity due to differences in genetic traits. This study evaluated the efficacy of peginterferon and ribavirin, and the association between IL28B genotypes and the treatment efficacy in Korean CHC patients. METHODS This was a retrospective(More)
