Fecal samples were taken from 402 cows in Posung, Chonnam where was designated as a place for Korean native cattle breeding. Prevalence of internal parasitisms were determined by the fecal examinations using the floatation and sedimentation procedures. 62.9% of the cows were found as positive cases with excretion of the eggs of Fasciola hepatica in the fecal specimens. Of those infected with F hepatica 97 cows free of other pathogenic intestinal parasites were chosen for albendazole treatment. Albendazole tablets(10mg/kg) were administered to the cows twice at the interval of 4 weeks. Blood samples were collected via jugular vein prior to the first treatment, four weeks after the first treatment and four weeks after the second treatment, respectively. At the same time fecal samples were collected for parasitological examinations by sedimentation methods. The mean pretreatment count was 44 fluke eggs per gram of feces, which compared with 27 epg and 17 epg four weeks after the first and second treatment, respectively. Most of the hematological and biochemical values fluctuated within the normal ranges during the experiment. Eosinophil counts were high initially, decreased after the first treatment and thereafter remained steady. The opposite was the case with aspartate and alanine aminotransferases.

Korean red ginseng, the processed root of Panax ginseng Meyer, has been frequently used for various therapeutic purposes in oriental medicine. The present study investigated the possible effect of Korean red ginseng extract (RGE) for the treatment of liver fibrosis in mice injected with carbon tetrachloride ($CCl_4$) for 4 wk. Liver injuries were assessed by blood biochemistry and histopathology in mice treated with $CCl_4$ alone or $CCl_4$+ RGE (30, 100, and 300 mg/kg). Concomitant treatment with RGE and $CCl_4$ (three times/wk for 4 wk) effectively inhibited liver fibrosis as evidenced by decreases in plasma alanine and aspartate aminotransferases, as well as by the percentages of degenerative regions, numbers of degenerative hepatocytes, and collagen accumulation in hepatic parenchyma. Treatment with $CCl_4$ for 4 wk increased mRNA levels of transforming growth factor ${\beta}1$ and plasminogen activator inhibitor 1 in fibrogenic liver, whereas RGE (30, 100, and 300 mg/kg) significantly blocked the induction of fibrogenic genes by $CCl_4$. Similarly, RGE also prevented transforming growth factor ${\beta}1$-mediated induction of fibrogenic genes in human hepatic stellate cell lines. More importantly, RGE markedly reduced the number of ${\alpha}$-smooth muscle actin-positive cells in liver tissue. This study implies that RGE efficaciously protects against the liver fibrosis induced by chronic $CCl_4$ treatment, and may therefore have potential to treat liver disease.

Purpose: We aimed to study the pattern of liver-injury in children with dengue fever (DF) and validate serum aminotransferase ${\geq}1,000IU/L$ as a marker of severe DF. Methods: Children admitted with DF were included. DF was defined by presence of clinical criteria and positive serological or antigen tests in absence of other etiology. DF severity was graded as dengue without or with warning signs and severe dengue. Liver-injury was defined as alanine aminotransferase (ALT) more than twice the upper limit of normal (boys, 30 IU/L; girls, 21 IU/L). Results: Of 372 children with DF, 144 (38.7%) had liver-injury. Risk of liver-injury and aminotransferase levels increased with DF severity (p<0.001). Recommended ALT and aspartate aminotransferase (AST) cut-off at ${\geq}1,000IU/L$ had sensitivity 4.8% (5/105), specificity 99.3% (265/267) for detection of severe DF. In children with ALT and AST <1,000 IU/L (n=365), the area under receiver operating curves for prediction for severe DF, were 0.651 (95% confidence interval [CI], 0.588-0.714; p<0.001) for ALT and 0.647 (95% CI, 0.582-0.712; p<0.001) for AST. Serum ALT at 376 IU/L and AST at 635 IU/L had sensitivity and specificity comparable to ${\geq}1,000IU/L$ for defining severe DF. Conclusion: Liver-injury is common in DF. The ALT and AST levels increase with DF severity. ALT and AST levels of ${\geq}1,000IU/L$ could be lowered to 376 IU/L and 635 IU/L respectively for defining severe DF.

Purpose: Liver metabolism plays a pivotal role in the development of metabolic disorders. We aimed to investigate the clinical and laboratory risk factors associated with alanine aminotransferase (ALT) levels in young adolescents from an urban population in Korea. Methods: A population of 120 apparently healthy adolescents aged 12-13 years was included in the cross-sectional design study; 58 were overweight or obese and 62 were of normal weight. We estimated anthropometric and laboratory measurements, including waist-to-height ratio, blood pressure, insulin sensitivity, aspartate aminotransferases (AST), ALT, and lipid profiles. Results: The mean ages of the overweight or obese and normal weight participants were $12.9{\pm}0.3$ and $13.0{\pm}0.3years$, respectively. Height, weight, body mass index, waist circumference, waist-to-height ratio, systolic and diastolic blood pressure, AST, ALT, total cholesterol, low-density lipoprotein-cholesterol, triglyceride, insulin, and the homeostatic model assessment of insulin resistance (HOMA-IR) score were significantly higher and the high-density lipoprotein-cholesterol and quantitative insulin-sensitivity check index were significantly lower in the overweight/obese participants in comparison to the normal-weight participants (all P<0.05). In multivariate linear regression analysis, waist-to-height ratio, systolic blood pressure, and HOMA-IR score were independently and positively associated with serum ALT levels. Conclusion: Screening for ALT levels in adolescents may help to differentiate those at risk of metabolic abnormalities and thus prevent disease progression at an early age.

Objective: The potential of extra virgin olive oil (EVOO), betaine (BET), and ginger (GIN), as natural antioxidants, in reducing negative effects of heat stress on physiological responses, antioxidant capacity, semen quality and fertility of bucks under heat stress were investigated. Methods: Forty adult Animal Production Research Institute line rabbit bucks were distributed randomly into four experimental treatments of ten rabbits each. The first treatment was fed the commercial pellet diet (CPD) without supplementation and served as a control. The other three treatments were fed CPD supplemented with EVOO (300 mg), BET (1,000 mg), and GIN (200 mg) per kg diet for 3 consecutive months during the summer season. Results: Supplementation of EVOO, BET, or GIN improved (p<0.05) the sexual desire, progressive motility, vitality, intact acrosome and membrane integrity, sperm cell concentration, sperm outputs and fertility. Seminal plasma total proteins, globulin, total antioxidant capacity, glutathione and glutathione S-transferase, and initial fructose increased (p<0.05), while total lipids, aspartate and alanine aminotransferases and malondialdehyde decreased (p<0.05) compared with the control. In comparing the natural antioxidants treatments, GIN evoked the largest improvement. Conclusion: The inclusion of GIN (200 mg/kg diet) appeared to improve the sexual desire, semen quality and oxidative stress of bucks. This may be a beneficial supplement for the management of rabbit bucks used in natural mating or artificial insemination.

목 적: 최근 사회 경제적 성장과 식생활의 서구화로 소아 비만의 빈도가 증가되고 있으며, 이에 따른 고지혈증, 고혈압, 당뇨, 지방간 등의 합병증의 비율이 높아지고 있다. 이에 저자들은 소아 비만에 따른 간기능 검사의 이상 정도와 총 콜레스테롤과 중성지방 증가 정도 및 공복 시 혈당과의 관계 여부를 조사하였고, 이에 따른 남녀 성별 간의 차이 및 관련 여부를 비교해 보았다. 방 법: 2005년 3월부터 2005년 11월까지 6세에서 12세까지 인천광역시 초등학교 학생 중 비만도 20% 이상인 비만 아동 1,507명과 정상 체중아 699명을 대상으로 비만도를 분류하였으며, 혈액검사를 실시하여 총 콜레스테롤, 중성지방, 포도당, AST, ALT를 측정하였다. 통계적인 분석은 chi-square test를 적용하였고 p value 0.05 미만일 때 유의한 것으로 판정하였다. 결 과: AST 수치 증가는 정상 아동군 3.4%, 경도 비만군 6.7%, 중등도 비만군 10.2%, 고도 비만군에서 11.5%를 보였으며, ALT 수치 증가는 정상 아동군 3.4%, 경도 비만군 11.4%, 중등도 비만군 18.4%, 고도 비만군에서 20.7%로 통계학적으로 유의한 차이를 보였다(p<0.0001). AST 수치 증가는 남아의 경우 정상군에서 4.9%, 경도 비만군 9.9%, 중등도 비만군 11.6%, 고도 비만군에서 13.7%였고, 여아인 경우 정상군에서 1.8%, 경도 비만군 3.0%, 중등도 비만군 7.5%, 고도 비만군에서 6.9%를 보였으며, 남녀 모두에서 비만도에 따른 AST 수치 증가는 통계적으로 유의하였다(p=0.0007, p=0.0039). ALT 수치 증가는 남아의 경우 정상군에서 5.1%, 경도 비만군 16.8%, 중등도 비만군 21.8%, 고도 비만군에서 24.7%였고, 여아의 경우 정상군에서 1.5%, 경도 비만군 5.1%, 중등도 비만군 11.6%, 고도 비만군 12.6%였다. ALT 수치 증가는 두 그룹에서 모두 통계적 유의성이 있었다(p<0.0001). AST와 ALT가 100 IU/L 이상인 학생을 대상으로 시행한 복부 초음파 검사에서는 비만 아동의 경우 모두 경증 혹은 중등도의 지방간 소견을 보였다. 비만 아동에서 콜레스테롤 수치 이상(${\geq}200mg/dL$)은 정상군에서 15.5%, 경도 비만군 21.0%, 중등도 비만군 19.1%, 고도 비만군에서 21.0%였고(p=0.058), 중성 지방 수치는 정상군 16.9%에 비해 경도 비만군 30.3%, 중등도 비만군 37.6%, 고도 비만군에서 38.2%로 통계적으로 유의하였다(p<0.0001). 성별 간 콜레스테롤 수치 이상(${\geq}200mg/dL$)은 남아에서 30.7%, 여아에서는 30.4%로 남녀 간에 비슷하였으나, 남녀 각각 중성지방 증가의 유병률은 비만 정도가 심할수록 증가하였다(p<0.0001). 결 론: AST 및 ALT 증가의 유병률은 정상아에 비하여 비만아에 더 높았고, 비만이 심해질수록 유의하게 높았다. 남아에서의 비만이 여아에서보다 심하였으며, 남녀 모두에서 비만도는 간기능 이상 및 중성지방과는 통계적 유의성을 보였다. 따라서 비만의 정도를 낮추는 대책을 강구하여야 할 것이며, 체중 감량을 비롯한 비만 치료 및 학생과 부모에 대한 효과적인 교육이 필요할 것으로 사료된다.
