Background: Apoptosis plays a role in the development of pleural effusion. Caspase-cleaved cytokeratin 18, a marker for epithelial cell apoptosis, was evaluated in pleural effusion. Methods: A total of 79 patients with pleural effusion were enrolled. The underlying causes were lung cancer (n=24), parapneumonic effusion (n=15), tuberculous effusion (n=28), and transudates (n=12). The levels of M30, an epitope of caspase-cleaved cytokeratin 18, were measured in blood and pleural fluids using enzyme-linked immunosorbent assay along with routine cellular and biochemical parameters. The expression of M30 was evaluated in the pleural tissues using immunohistochemistry for M30. Results: The M30 levels in pleural fluid were significantly higher in patients with tuberculosis ($2,632.1{\pm}1,467.3U/mL$) than in patients with lung cancer ($956.5{\pm}618.5U/mL$), parapneumonic effusion ($689.9{\pm}413.6U/mL$), and transudates ($273.6{\pm}144.5U/mL$; all p<0.01). The serum levels were not significantly different among the disease groups. Based on receiver operating characteristics analysis, the area under the curve of M30 for differentiating tuberculous pleural effusion from all other effusions was 0.93. In the immunohistochemical analysis of M30, all pathologic types of cancer cells showed moderate to high expression, and the epithelioid cells in granulomas showed high expression in tuberculous pleural tissues. Conclusion: Caspase-cleaved cytokeratin 18 was most prominently observed in tuberculous pleural effusion and showed utility as a clinical marker. The main source of M30 was found to be the epithelioid cells of granulomas in tuberculous pleural tissues.

Inhaled halogen compound was examined through micronucleus tests and toxicity tests using SD (Sprague-Dawley) rats with repeated dosages for six hours a day, five days a week, during four weeks. In four-week repeated exposure, no specific sign caused by the $CF_3I$ compound was observed on the clinical symptoms, body weight variation, feed consumption, and urinalysis data in the testing groups with reference to the control group. In hematological and biochemical blood tests of the testing groups, the significant, but in their normal ranges, value dependencies of glucose, aspartate aminotransferase, alanine aminotransferase and etc., on the halogen carbohydride concentration was observed. In histo-pathological tests, no specific lesion or concentration dependent change due to the $CF_3I$ compound dosage was observed in both sexes of the female and male in the tested animals. But, micronucleus tests on marrow cells extracted from the tested animals which were repeatedly exposed in the $CF_3I$ compound during four weeks, the frequencies of micronuclei were significantly increased dose-dependently compared to the control groups.

선천성 고혈압 흰쥐를 이용하여 puromycin Aminonucleoside (PAN)로 유도된 미세 변화신증에 대한 $\alpha$-tocopherol acetate의 효과를 알아보기 위하여, 정상군, PAN 투여군 (30 mg/kg), 비타민 E 투여군 (200 mg/kg) 그리고 PAN+비타민 E 투여 군으로 나누었다. 각 군은 약물 투여 후 2, 4, 8, 16일째 처치하여 혈청 생화학적 변화, 조직학적 변화, 그리고 미세구조적 변화를 관찰하였다. 실험동물의 체중은 PAN 투여군이 가장 낮은 증가율을 보였고, 비타민 E 투여군이 가장 높은 증가율을 보였다. 혈청 총단백질의 함량은 PAN투여 8일군에서 가장 낮았고, 혈중 요소성 질소와 크레아티닌의 함량은 P투여 8일군에서 가장 높게 나타났다. PAN+비타민 E 투여군에서는 PAN 투여군과 비교하여 혈청 총단백질의 함량이 증가되었고, 혈중 요소성 질소와 크레아티닌의 함량은 감소되었다. 조직학적 관찰 결과, 요세관 공간의 소실과 혈관사이세포의 증식이 PAN 투여 4일군에서 나타나기 시작하여, PAN투여 8일군에서 가장 현저하였으나 비타민 E 투여로 이러한 변화 정도는 감소되었다. PAS 염색 관찰 결과, 염색 정도가 PAN투여 8일군에서 가장 강하게 나타났고, 비타민 E 투여로 염색 정도는 감소되어 나타났다. 미세구조의 변화는 PAN투여 8일군에서 족돌기의 융합과 소실, 모세 혈관 내피세포의 공포화, 그리고 혈관사이세포와 사구체 기저막의 증식이 관찰되었고, 비타민 E투여로 감소되었다. 이러한 결과들로 보아 PAN으로 유도된 사구체 손상은 고혈압에 의해 가중될 수도 있으며, 사구체의 기능이상은 산화적 손상에 의한 것임을 간접적으로 시사하고 있다.

Heme oxygenase-1 (HO-1) degrades heme to carbon dioxide, biliverdin, and $Fe^{2+}$, which play important roles in various biochemical processes. In this study, we examined the protective function of HO-1 against oxidative stress in SH-SY5Y cells and in a Parkinson's disease mouse model. Western blot and fluorescence microscopy analysis demonstrated that PEP-1-HO-1, fused with a PEP-1 peptide can cross the cellular membranes of human neuroblastoma SH-SY5Y cells. In addition, the transduced PEP-1-HO-1 inhibited generation of reactive oxygen species (ROS) and cell death caused by 1-methyl-4-phenylpyridinium ion ($MPP^+$). In contrast, HO-1, which has no ability to transduce into SH-SY5Y cells, failed to reduce $MPP^+$-induced cellular toxicity and ROS production. Furthermore, intraperitoneal injected PEP-1-HO-1 crossed the blood-brain barrier in mouse brains. In a PD mouse model, PEP-1-HO-1 significantly protected against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced toxicity and dopaminergic neuronal death. Therefore, PEP-1-HO-1 could be a useful agent in treating oxidative stress induced ailments including PD.

감각신경성 난청은 성인에서 장애의 원인 중 큰 비중을 차지하고 있으며, 특히 소음성 난청은 흔한 직업병 중의 하나이며 산업보건사업의 주요 관심 중의 하나이다. 그러나 소음폭로와 노화를 제외하고는 대부분의 경우 그 원인이 규명되지 않고 있는 실정이다. 그러므로 난청에 대한 개인간의 감수성을 결정하는데 중요한 요인을 찾는 것은 중요하며 최근 청력손실의 측정치로서 소음 외 변수와의 상관성을 연구함으로써 청력손실에 대한 개인의 감수성의 차이를 밝히려는 많은 시도가 있었다. 특히 소음성 난청에 대한 많은 연구가 있어 왔지만 소음성 난청에 대한 감수성의 개인차에 대해서는 만족하게 설명하지 못하고 있다. 본 연구는 소음 비폭로자를 대상으로 소음폭로 이외 감각신경성 난청을 유발하는 잠재적 위험 인자들을 찾아내어 그 위험인자들의 역할을 평가하기 위해 주로 심혈관 위험인자와 지혈 및 혈액점도 요인이 청력손실에 미치는 영향에 대해 조사하였다. 대구시내 모 대학병원에서 91년에서 96년까지 종합검진을 받은 3050명을 대상으로 하여 청력검사와 혈액검사 및 생화학 검사 결과를 검진자료에 추출하여 위험인자들과 청력손실간의 관련성을 연구하였다. 그 결과 소음을 제외하고 감각신경성 청력손실에 미치는 영향으로 연령과 성별이 가장 크며, 성별 분포의 차이는 연구 변수에는 포함되지 않는 흡연력, 취미, 과거 소음폭로 등이 영향을 미친 것으로 보이며 본 연구에서는 확인할 수 없었다. 그리고 심혈관 위험인자인 체격지수, 혈압, 총콜레스테롤, 중성지방이 양의 영향을 알부민은 음의 영향을 어느 정도 미치는 것으로 보인다. 혈중점도 및 지혈인자와 관련하여 헤마토크릿, 백혈구, 혈소판 용적백분율, 적혈구침강속도가 어느 정도 양의 관련성이 있는 것으로 나타났다. 그리고 심혈관 위험인자와 혈액점도 및 지혈인자는 상호 관련성이 있으며, 이들과 소음노출 등이 서로 상호 작용하여 청력에 나쁜 영향을 미치는 것으로 보인다.

An experiment was conducted to investigate the effect of feeding transgenic cottonseed (Bt.) vis-a-vis non-transgenic (non-Bt.) cottonseed on blood biochemical constituents in lactating Murrah buffaloes. Twenty Murrah buffaloes in mid-lactation were divided into 2 groups of 10 each. Animals of group I were fed with 39.5% non-transgenic cottonseed in concentrate mixture while the same percentage of transgenic (Bt.) cottonseed was included in the concentrate mixture fed to the animals of group II. Animals of both groups were fed with concentrate mixture to support their milk production requirements. Each buffalo was also offered 20 kg mixed green fodder (oats and berseem) and wheat straw ad libitum. The experimental feeding trial lasted for 35 days. There was no significant difference in the dry matter intake between the two groups of buffaloes. All the buffaloes gained body weight, however, the differences were non significant. Total erythrocyte count, hemoglobin content and packed cell volume were $9.27{\pm}0.70${\times}10^6/{\mu}l$, $13.01{\pm}0.60gdl$ and $34.87{\pm}1.47%$, respectively in group I with the corresponding figures of $8.88{\pm}0.33$, $12.99{\pm}0.52$ and $31.08{\pm}1.52$ in group II. The values of total erythrocyte count, haemoglobin content and packed cell volume did not differ significantly between the two groups of buffaloes. The concentration of plasma glucose, serum total proteins, albumin, globulin, triglycerides and high density lipoprotein were non significantly higher in buffaloes fed non-transgenic cottonseed than in buffaloes fed transgenic cottonseed. The cholesterol concentration was significantly (p<0.01) higher in buffaloes of group I ($136.84{\pm}8.40mg/dl$) than in buffaloes of group II ($105.20{\pm}1.85mg/dl$). The serum alkaline phosphotase, glutamic-oxaloacetate transaminase and glutamic-pyruate transaminase activities did not differ significantly between two groups of buffaloes. However, serum glutamic-pyruate transaminase activity was considerably high in buffaloes fed nontransgenic cottonseed as compared to buffaloes fed transgenic cottonseed. Bt. proteins in serum samples of animals of group II were not detected after 35 days of feeding trial. It was concluded that transgenic cottonseed and non-transgenic cottonseed have similar nutritional value without any adverse effects on health status of buffaloes as assessed from haematobiochemical constituents.

Background: There is paucity of studies defining the prevalence of non-communicable disease (NCD) risk factors in Saudi Arabia despite the surging epidemic of obesity, change in dietary habits and sedentary lifestyle. Objectives: This cross-sectional study aimed to assess the prevalence of NCDs risk factors among employees at King Faisal University in Al Hassa, Saudi Arabia and to determine the possible correlates for clustering of NCDs risk factors among them. Materials and Methods: All employees were invited to participate; the World Health Organization STEPwise approach was used for data collection which consisted of a personal interview to collect socio-demographic characteristics, NCD history, tobacco use, vegetables and fruit consumption, and physical activity (PA), followed by anthropometric measurements namely weight, height and waist circumference and blood pressure measurements, subjects were finally subjected to biochemical tests with determination of fasting plasma glucose, serum triglycerides, cholesterol and high density lipoproteins. Results: Of the surveyed employees (n=691), daily current smokers accounted for 22.7%. 94.9%, 95.1% and 86% consumed < 5 servings per day of vegetables, fruits and both fruits and vegetables respectively, 73% were physically inactive, 64% were overweight or obese, 22.1% had hypertension, and 21.5% were diabetics. Elevated cholesterol levels were found in 36.6%, low high density lipoproteins in 36.8%, and elevated triglycerides in 36.1%. Only 3% had no NCD risk factors, and 57.6% had ${\geq}3$ factors. Multivariate logistic regression showed that gender (being male, adjusted odds ratio 'aOR'=1.51), aged ${\geq}50$ years (aOR=3.06), < college education (aOR=1.75), current smokers (aOR=2.37), being obese (aOR=6.96) and having a low PA level (aOR=4.59) were the significant positive predictors for clustering of NCD risk factors. Conclusions: Over fifty percent of the studied university's employees had multiple (${\geq}3$) NCD risk factors. Screening and health promotion initiatives should be launched at least targeting the modifiable factors to avert the excessive risk for cardiovascular disease, diabetes mellitus and several types of cancers.

Changes in hematology and serum biochemistry after treatment of recombinant human erythropoietin (rHuEPO, HM10760) were screened in 4 male cynomolgus monkeys (Macaca fascicularis). Four monkeys, composed of a treatment group of HM10760 and a positive control group of $Aranesp^(R}$, were subcutaneously administered at same dose of $100{\mu}g/kg$. Both groups did not show any change in body weights and food consumption for 4 weeks compared with those of pretreatment. Both groups did not show any change in total leukocyte count (WBC) and platelet count, while both groups showed increased platelet distribution width (PDW) percentage in HM10760 group during a period from day 5 to day 59 and in $Aranesp^(R}$ group during a period from day 9 to day 26. Both groups showed increases in red blood cells (RBC), hemoglobin (HGB), and hematocrit (HCT) approximately 10 days after treatment compared with those of pretreatment (day 0). The increased levels of RBC, HGB, and HCT were much higher in HM10760 than in $Aranesp^(R}$ by the increases of $3.2%{\sim}12.5%$ for RBC, $3.8%{\sim}17.1%$ for HCT, and $1.85%{\sim}11%$ for HGB. Both groups showed increases in red cells distribution width (RDW) and reticulocyte (RET) compared with those of pretreatment, showing the highest peak from day 9. The increased level of RET lasted up to day 14 in $Aranesp^(R}$ group, while it lasted up to day 23 in HM10760 group. The increased level of RDW lasted up to day 59, it was much higher in HM10760 by the increase of $10.1%{\sim}17.6%$ than in $Aranesp^(R}$ group. In serum biochemistry, both groups showed a decrease in chloride level compared with those of pretreatment. These findings indicated that HM10760 increased RBC, HGB, HCT, RDW, and RET compared with those of pretreatment, and the increased levels were much higher in HM10760 than in $Aranesp^(R}$.
