There are controversial findings regarding the roles of nuclear factor (erythroid-derived 2)-like 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway on bone metabolism under oxidative stress. We investigated how Nrf2/HO-1 pathway affects osteoblast differentiation of MC3T3-E1 cells in response to hydrogen peroxide (H2O2), N-acetyl cysteine (NAC), or both. Exposing the cells to H2O2 decreased the alkaline phosphatase activity, calcium accumulation, and expression of osteoblast markers, such as osteocalcin and runt-related transcription factor-2. In contrast, H2O2 treatment increased the expression of Nrf2 and HO-1 in the cells. Treatment with hemin, a chemical HO-1 inducer, mimicked the inhibitory effect of H2O2 on osteoblast differentiation by increasing the HO-1 expression and decreasing the osteogenic marker genes. Pretreatment with NAC restored all changes induced by H2O2 to near normal levels in the cells. Collectively, our findings suggest that H2O2-mediated activation of Nrf2/HO-1 pathway negatively regulates the osteoblast differentiation, which is inhibited by NAC.

Mesenteric venous thrombosis is a rare disease accounting for 5-15%. MVT is generally difficult to diagnose and can be fatal because of delayed diagnosis and treatment. A case of extensive thrombosis of the mesenteric vein was diagnosed early and successfully treated in a 70-year-old female who was admitted to hospital because of bloody diarrhea and abdominal pain. Computed tomography(CT) showed remarkable thickening of the bowel walls and extensive thrombosis of superior mesenteric vein. Because intestinal infarction and peritonitis was seen, emergency operation was done and catheter-directed thrombectomy through mesenteric vein was successfully performed. She discharged without any complications.
Fatigue Crack Growth Behavior in Ultrafine Grained Low Carbon Steel
Ho,Kyung Kim,Myung-Il Choi,Chin-Sung Chung Dong-Hyuk Shin 대한기계학회 2002 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.16 No.10
Ultrafine grained (UFG) low carbon (0.15 wt.% C) steel produced by equal channel angular pressing (ECAP) was tested for investigating the effect of load ratio on the fatigue crack growth rate. Fatigue crack growth resistance and threshold of UFG steel were lower than that of as-received coarse grained steel. It was attributed to the less tortuous crack path. The UFG steel exhibited slightly higher crack growth rates and a lower △K_th with an increase of R ratio. The R ratio effect on crack growth rates and △K_th was basically indistinguishable at lower load ratio (R>0.3), compared to other alloys, which indicates that contribution of the crack closure vanishes. The crack growth rate curve for UFG steel exhibited a longer linear extension to the lower growth rate regime than that for the coarse grained as-received steel.<br/>

Limy bile is a rare condition characterized by excessive precipitation of calcium carbonate in the gallbladder or bile duct. Recently we experienced two cases with obstructive jaundice in which limy bile in the common bile duct but not in the gallbladder for one case, and in the common bile duct and intra hepatic duct but not in the gallbladder for another case. The patients were treated by endoscopic sphincterotomy. Here, we report the cases and review the literature.

This research intends to examine the physical fitness factor of high school and university mate tennis players. Eight tests were performed and the factor analysis was used to examine the fitness level. Therefore, we will now discuss this research's conclusion. Within the factor structure, three factors for high school males(strength, endurance, agility), and four factors for university males(endurance, agility, strength, flexibility) were sampled and we can see that university athletes are more specialized than high school athletes. Therefore, we can see that for high school students, strength is an important factor, while for university students, endurance is an important factor.
여성 알코올 의존 환자의 임상적 특성에 관한 연구 : - 일 정신병원 입원환자를 중심으로 -
성상경,신동환,송종호,이규항 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.6
연구목적: 남. 여 알코올의존 환자의 인구통계학적 특성, 음주력, 가족력, 음주양상, 음주동기, 공유질병 등을 포함하는 임상적 특성의 차이 및 여성 알코올의존에 대한 질병양상과 그 가족의 태도를 파악함으로써 향후 여성 알코올의존 환자의 치료 대책수립을 위한 기초자료를 제공하는데 그 목적이 있다. 방 법: 1991년 1월1일부터 1996년 5월31일까지 일 정신병원에 입원 치료한 남. 여 각각 51명의 알코올의존 환자를 연구대상으로 하였으며, 연구방법으로 병력기록지 및 설문지 조사를 통한 자료 수집을 이용하였다. 양군간의 비교를 위해 남. 여 인원 및 나이를 통제하였고, 여성 알코올의존자의 평균 연령은 44.45±11.02세였고 남성 환자군의 평균 연령은 44.17±10.08이었다. 진단은 DSM-Ⅲ-R에 의해 이루어졌으며 대상자 모두는 알코올 의존의 진단기준을 만족하였다. 결 과: 여성 알코올의존자는 남성 알코올의존자에 비해 음주시작 연령이 늦었고 과거 음주기간은 짧았으며 일 음주량이 적었다. 그리고 여성 알코올의존자는 남성 알코올의존자에 비해 자발적 입원이 많았으며 입원후 금단증상, 알코올성 간염, 당뇨등 신체적 합병증이 적었다. 또한, 입원후 가족의 태도에서 가족의 이혼위협 등 치료에 비협조적인 경우가 남성 알코올의존자에 비해 많았으며, 과거력상 사별, 이혼, 남편의 구타 등 상실의 경험이 많았다. 결 론: 남. 여 알코올의존자간에 인구통계학적 특성, 임상 특성, 가족의 태도 등 여러가지 면에서 차이가 나는 것으로 나타났다. 여성 알코올의존자 집단은 가족의 죽음, 부부생활의 갈등과 같은 심리 사회적 좌절 경험이 더 많고 가족들이 더 비협조적이었다. 그러므로 치료자는 이러한 여성알코올의존자의 특성을 치료와 예방에 반영하고 이들에 대한 세심한 배려를 해야할 것이다. Objectives: This study aimed to provide a basic data of female alcoholics by understanding the gender differences of the clinical characteristics including demographic characteristics, alcoholic history, family history, drinking patterns, reasons for drinking, and comorbidity in male and female alcoholics. It also ained to establish the therapeutic plans through understanding the patterns of disease and the patterns of family cooperation in female alcoholics. Methods: The study subjects consisted of 51 male and female alcoholics admitted to a mental hospital from January 1, 1991 to May 31, 1996. Subjects were age-and sex-matched. We reviewed patients charts and administered questionaires. Mean age of female alcoholics was 44.45±11.02 years and that of male alcoholics was 44.17±10.08 years. All male and female patients met with the DSM-Ⅲ-R criteria of alcohol dependence. Results: Female alcoholics were later in drinking-onset age, and to had shorter duration of previous drinking history and less average amount of daily drinking than male alcoholics. And female alcoholics were found to seek treatment more voluntarily, and to have less frequent delirium tremens after admission and less medical complications such as hepatitis and diabetes mellitus. Also female alcoholics had more frustration experiences of separation such as death of family member, divorce, and husband`s physical abuse. Female alcoholic`s families had more uncooperative attitude toward treatment such as threat to divorce after admission. Conclusions: There were many differences between male and female alcoholics of demographic characteristics, clinical characteristics, and patterns of family cooperation. Female alcoholics were found to have more experiences of psychosocial frustration including death of family member and marital conflicts, and more uncooperative attitude of her family members. Therefore, it is required that therapists consider the characteristics of female alcoholics upon treatment and prevention, and have more concern about female alcoholics.
