This study examined the health conditions of schoolteachers in terms of the prevalence rate and risk factors for liver disease. A cohort design was conducted for 21,319 teachers who were born from 1953 to 1957. The cohort was constructed for teachers who had no disease history such as liver disease, hypertension, cerebral vascular disease, heart disease, diabetes mellitus and cancer, and had 'normal' results from liver disease examinations in 1998. They were followed up from 1998 to 2000. SAS 6.12 was used for the data analysis. The results were as follows; (1) Prevalence rates of liver disease per 1,000 people in 1998 were 43.0. (2) The 2-year cumulative incidence of liver disease was 433/16,103(26.9/1000 persons). (3) Factors such as sex, age, school type(private or public), drinking, smoking, exercise, BMI, weight gain, fasting-blood sugar levels and total cholesterol levels were statistically significant. The significant risk factors of liver disease be identified from the multiple logistic regression analysis were age, sex(male), drinking, smoking, BMI, weight gain, fasting-blood sugar levels, and total cholesterol levels.

Gender differences in the effects of gonadectomy and high cholesterol diet on body weight and body cholesterol were investigated by using Sprague Dawley rats. Body weight, plasma and liver levels of cholesterol and triglyceride and platelet aggregation were examined in ovariectomized(OVX) or orchidectomized(ODX) rats with their intacts after feeding diet with or without 0.5% cholesterol. Body weight was significantly increased(p < 0.01) in OVX rats and significantly decreased(p < 0.01) in ODX rats compared to their respective intact rats, and cholesterol diet significantly(p < 0.05) decreased body weight in gonadectomized rats. Liver lobes from rats fed cholesterol diet were opaque and larger than those from rats find control dict, resulting in a significant increase(p < 0.01) in LW/BW ratio. Plasma and liver levels of total cholesterol were significantly increased (p < 0.01) in female rats regardless ovariectomy when find 0.5% cholesterol diet, but those levels in male rats were increased only when they were orchidectomized(p < 0.0l). Plasma HDL-cholesterol was significantly decreased(p < 0.05) in both sexes when find cholesterol diet. HDL-cholesterol were higher in female than male rats regardless treatments(p < 0.05). Liver triglyceride was significantly increased(p < 0.05) in both sexes when find cholesterol dict. Plasma level of triglyceride was not different among groups except significant decrease(p < 0.05) in cholesterol find ODX rats. Maximum platelet aggregation in female rats was significantly lower(p < 0.05) than male, but ovariectomy and cholesterol diet caused an increase te the level of male rats. Microscopic examination showed cholesterol diet caused a lipid accumulation in liver. Results indicate that intact female rats have higher response to hypercholestcrolemic diet than intact male rats and orchidectomy causes male rats more responsive to hypercholesterolemic diet. However, ovariectomy causes an increase female food efficiency ratio to the level of male rats, significantly increasing body weight.

Objectives : The aim of this study was to evaluate the effect of aqueous extracts of Mume Fructus(MF) on the 6-n-propyl-2-thiouracil(PTU)-induced rat hypothyroidism.Methods : Aqueous extracts of MF(yield = 19.38%) were administered, once per day for 42 days from 2 weeks before starting of PTU treatment as an oral dose of 300 and 150 ㎎/㎏(body weight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 ㎎/㎏ for 28 days. The changes in the body weight, thyroid gland weights, liver weight, serum levels of thyroid hormone-thyroid stimulating hormone(TSH), tri-iodothyronine(T₃) and thyroxine(T₄), total cholesterol, low density lipoprotein(LDL), high density lipoprotein(HDL) and triglyceride (TG), aspartate aminotransferase(AST), alanine aminotransferase(ALT), liver antioxidant defense system-lipid peroxidation, H₂O₂, superoxide dismutase(SOD) and catalase(CAT) were examined with histopathology of thyroid glands and liver.Results : Results were compared with LevoT₄0.5 ㎎/㎏ treated rats. MF extracts recovered from the decreases in the body weight, liver weight, T₃and T₄, TG, liver CAT activities as results of PTU treatment. And MF extracts recovered from the increases of thyroid gland weights, TSH, HDL contents, liver H₂O₂, AST as results of PTU treatment. In addition, these PTU-induced histopathological changes in thyroid glands and liver related to hypothyroidism were dramatically decreased by treatment of both different dosages of MF extract, respectively.Conclusions : According to the above results, it is suggested that MF extracts have advantageous effects on the thyroid hormone productions with beneficial effects on the hypothyroidism related liver injuries mediated by the modulation on the antioxidant system.

Panax ginseng occupies an important role in the folk medicine of China, Korea and Japan. The present study was undertaken to determine the radioprotective efficacy of ginseng root extract in the liver of Swiss albino mice. The animals were divided into 4 groups. Group I-Only vehicle was administered. Group II-The animals received 10 mg/kg body weight ginseng root extract i.p. for 4 consecutive days. Group III-Animals were irradiated with 8Gy gamma radiation at the dose rate of 1.69 Gy/min at the distance of 80 ems. Group IV-Animals were given by ginseng root extract (10 mg/kg body weight) continuously for 4 days and on 4th day they were irradiated with 8 Gy gamma radiation after 30 min. The animals from above groups were autopsied on 1,3,7,14 and 30 days. Biochemical estimations of phosphatases (acid ＆ alkaline), LDH (lactate dehydrogenase), LPO (lipid peroxidation) and GSH (reduced glutathione) in liver and SGOT (serum glutamate oxaloacetate transaminase), SGPT (serum glutamate pyruvate transaminase) and alkaline phosphatase in serum were done. In ginseng treated group acid phosphatase (ACP), alkaline phosphatase (ALP), LPO and LDH in liver and SGOT, SGPT and alkaline phosphatase in serum did not show any significant alteration. However, a significant increase in GSH content in liver was recorded. In irradiated group there was a significant increase in ACP, ALP and LPO content in liver and SGOT ＆ SGPT in serum was noted. Whereas, a significant decrease was recorded in GSH and LDH activity in liver and alkaline phosphatase activity in serum. Pretreatment of ginseng with radiation significantly alters the biochemical parameters in liver and serum. A significant decline in ACP, ALP activity and LPO content in liver and SGOT and SGPT activity in serum was observed. However, a significant increase in GSH content and LDH activity in liver and ALP activity in serum was estimated. The present study suggests that pretreatment of ginseng before irradiation significantly protects the liver and maintains the enzyme activity.

This study was performed to investigate the influence of dietary and extract foods from A. capilliaris Thunberg on plasma and liver lipid metabolism in male Sprague-Dawley rats. For the experiment of liver and plasma lipid metabolism, Rats were find diets containing normal concentrations of fat or high concentrations of lard and two different preparations of A. capillaris Thunberg ; control diet (group C),50 mg/kg body weight A. capillary Thunberg methanol extract (group M), 6 g/kg diet A. capillary Thunberg dried powder (group P), high lard control diet (group L), 50 mg/kg body weight A. capillaris Thunberg with high lard (group LM) and 6 g/kg diet A. capillary Thunberg with hi\ulcorner lard (group LP). Effects of A. capillary Thunberg on plasma total cholesterol. High-density lipoprotein (HDL) cholesterol, Atherogenic index, triglyceride, plasma and liver peroxide contents, fatty acid composition of liver lipid and the distribution of fat droplets of liver. Supplementation of A. capillaris Thunberg resulted in lower plasma cholesterol, atherogenic index and triglyceride, and higher HDL-cholesterol in rats find high lard diets. However, these effects were not observed with low level of fat (groups C, M and P). A shift caused by feeding high lard diets in increased plasma and liver peroxides, saturated fatty arid composition of liver lipid and the more frequent distribution of fat droplets in liver could be reversed by feeding A. capillary Thunberg. This study suggests that A. capillary Thunberg co alter lipid metabolism in plasma and liver.

Objectives : The aim of this study is to investigate the preventive effect of Puerariae Flos ethanol extract (PE) on methionin and choline deficient (MCD)-diet-induced Nonalcoholic fatty liver disease (NAFLD) in C57BL/6J mice. Methods : In the in vivo experiments, C57BL/6J mice were divided into 4 groups; Normal group, Control group, MCD+PE 100 group, and MCD+PE 300 group. After 4 weeks, body weight, liver weight, biochemical parameters for liver function test, histological changes, reverse transcription polymerase chain reaction (RT-PCR), and Western blot were assessed. Results : Mice lost body weight with the MCD-diet and the MCD+PE 100 group and MCD+PE 300 groups lost less than the control group, though showed no statistical significance. Liver weights were decreased by the MCD diet, but MCD+PE 300 groups were increased significantly. In the liver function test, all the values were decreased with the MCD-diet, MCD+PE 100 group and MCD+PE 300 groups were increased significance. In histological findings of the livers, MCD-diet induced severe fatty accumulation in the livers, but this fatty change was reduced in the MCD+PE 100 group and MCD+PE 300 groups was inhibited respectively. In lipid accumulation factors (such as SREBP-1c, $C/EBP{\alpha}$, PPAR-${\gamma}$), MCD+PE 100 group and MCD+PE 300 groups showed inhibitory effect on liver lipogenesis by reducing associated gene expressions caused by MCD diet. Conclusions : We were able to know that Puerariae Flos ethanol extract (PE) shown hepatoprotective effects via a decrease on the hepatic lipogenesis factors in the experimental NAFLD Models.

Effect of the butanol fraction of Astragali Radix (BFAR) on the humoral immune response were investigated in ICR mice. Mice were divided into 4 groups and BFAR at doses of 5,25 and 125 mg/kg were administered orally to mice daily for 3 weeks, and the normal animals were given vehicle. The results of this study are summarized as follows; the relative weight of spleen was markedly increased by BFAR treatment, compared with that in normal mice. However, the body weight gain and the relative weight of liver were not affected. Splenic plaque forming cells and hemagglutination titers to sheep red blood cells, and the secondary IgG antibody response to bovine serum albumin were also dose-dependently enhanced by BFAR treatment. In these mice, BFAR did not increase serum alanine aminotransferase total protein, sect albumin and albumin/globulin ratio when compared with those in normal mice. Thus, these findings indicate that BFAR significantly enhances humoral immune response to antigen in concentrations that do not affected liver function.

This study designs to investigate effects of onion diet on carbon tetrachloride toxicity of rats. Experiments were performed with week's feeding, body weight, food intake, ratio of orgen weight/dody weight, serum lipid levels, superoxide dismutase and catalase activity and malondialdehyde(MDA) content in liver and kidney were determined. The content of serum total cholesterol in each group were lower than those of control group(p<0.05), especially at onion juice treated group. Serum HDL-cholesterol level of CBB and CBJ groups was significantly lower than that of control group (p<0.05). Superoxide dismutase activities of liver and kidney were significantly increased by carbon tetrachloride treatment and decreased by onion feeding. MDA contents in liver and kidney of CCl4 treated rats were significantly decreased by boiled and fresh onion fed group, compared with CCl4 treated control group. This result suggested that onion diet has a protective effect of CCl4 induced hepatotoxicity and nephrotoxicity of rat.
