Effects of restraint stress and its modulations by ursodeoxycholic acid(UDCA) were evaluated on some biochemical and biophysical parameters in rats. Restraint stress induced elevations in blood alkaline phosphatase (ALP). cholesterol (CHOL), aspartate transaminase (GOT), alanine transaminase (GPT), lactate dehydrogenase (LDH) levels. It was also caused adrenal hypertrophy, decrease in weight of spleen and contents of ascorbic acid in stressed rats. As a results, stress indicators such as spleen, ascorbic acid, GOT, GPT, LDH were fastly changed after imposing stress, but those such as ALP, CHOL, adrenal were induced relatively later. UDCA was tested if it has an inhibitory effect against 18-hr restraint induced stress. UDCA lowered ALP, CHOL, LDH level and also effectively elevated the ascorbic acid contents in 25 mg/kg dosage of UDCA. In organ weights. the restraint stress induced increases in spleen and adrenal were attenuated by UDCA in 50 mg/kg dosage. However. stress-induced GOT and GPT levels were unaffected by UDCA.

The following results were made by observation GOT, GPT, ALP, total cholesterol and higlyceride in serum to research the effects of medicines which are Injinsaryungsan(Sample- A) and another medicine(Sample-B) of which Injin(Artemisiae Capillaris Herba)was increased in quantity on liver damaged by $CCl_4$ and d-galactosamine in rats. 1. The high concentrated extracts of Sample A group and Sample- B group showed significant inhibltory effects on the increase of serum GPT, ALP, LDH, total cholesterol and triglyceride levels induced by $CCl_4$ and d-galactosamine. 2. The high concentrated extracts of sample A group and Sample B group showed more significant inhibitory effects(P〈0.001) than the low ones' effects(P〈0.01) on the increase of serum triglyceride level induced by $CCl_4$ 3. Sample-A group showed significant inhibitory effects on the increase of serum GOT, GPT. ALP, total cholesterol and triglyceride levels, but no significance on the increase of serum LDH level induced by d-galactosamine. 4. Sample-B group showed very significant inhibitory effects on the increase of serum GOP, GPT, ALP, LDH, total cholesterol and triglyceride levels induced by d-galactosamine. 5. As compared with Sample-A group, Sample-B group of which Injin was increased in quantity showed more significant inhibitory effects on all items of this experiment induced by $CCl_4$ and d-galactosamine. As mentioned above. it seemed that both Injinsaryungsan and another medicine of which Injin was increased in quantity had effects protecting liver and anti-fatty liver induced by $CCl_4$ and d-galactosamine in rats. Specially Sample-B group had very significant effects on liver damage as compared with Sample-B group. Therefore it seems that more researches on variation according to the increase of Injin dose must be continued for curing liver diseases.

The present study was conducted to evaluate the hepatoprotective effect of puerariae Radix methanol extract on benzo(a) pyrene(B(a)P) - induced liver injuries in rats. In vitro experiment, primary cultured hepatocytes (5X105 cells/$m\ell$) were cultured for 20~24 hours after adding puerariae Radix mehtanol extract(32$\mu\textrm{g}$/$m\ell$) and B(a)P(50 uM). In vivo experiment, Puerariae Radix methanol extract(0.25 g/kg/day, per os) was administered for 7 days and B(a)P(0.1 mg/kg/day, intraperitoneally) was given after the last administration of extract. And then the hepatoprotective effect of Puerariae Radix methanol extract was investigated biochemically through in vitro and in vivo experiments. Namely, activities of enzymes (GOT, GPT and LDH) were measured and 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide(MTT) assay were carried out in vitro cell culture study and GOT, GPT, LDH and ALP activities and HDL-cholesterol, total cholesterol and triglyceride contents were performed in vivo study. In vitro experiment, as a result of enzyme activity measurement(GOT, GPT and LDH) and MTT assay, GOT,GPT and LDH activities changed by B(a)P were recovered to normal levels and hepatocytes impaired by B(a)P were recovered to normal. In vivo experiment, Puerariae Radix methanol extract significantly decreased the enzyme activities(GOT, GPT, ALP and LDH in serum and GPT and ALP in tissue) and lipid contents in comparison to B(a)P-treated group.

The purpose of this study was to investigate the relationship between nutrient intakes and blood parameters of cardiovascular function in 40 female college students on self-selected diet in Chungnam. Anthropometric measurements, analysis of dietary intakes and blood composition were conducted. Serum levels of triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol, CK-MB, and LDH were measured by biochemical analyzer. The results were summarized as follows. The mean age of the subjects was 22.5$\pm$1.2 years. The weight, height and BMI were 52.4$\pm$7.2kg, 161.3$\pm$5.7cm and 20.2$\pm$2.4, respectively. Daily energy and lipid intakes were 1634.2$\pm$ 437.7kcal and 46.8$\pm$17.0g. And the ratio of carbohydrate, protein, and lipid to energy intake was 59.2 : 14.5 : 26.3. Serum concentrations appeared to be 61.1$\pm$ 24.2mg/dl(triglyceride), 141.2$\pm$330.mg/dl(total cholesterol), 64.8$\pm$ 20.1mg/dl(HDL-cholesterol), 64.1$\pm$ 25.4mg/dl(LDL-cholesterol), 7.2$\pm$3.2IU/l (CK-MB), 107.9$\pm$23.4IU/l (LDH). In the relation between nutrient intakes and serum parameters, vitamin $B_1$ intake showed positive correlation with triglyceride, HDL-cholesterol, and CK-MB, respectively(p<0.001, p<0.05, p<0.05). Vitamin $B_2$intake had positive correlation with triglyceride(p<0.05). And vitamin C intake had negative correlation with HDL-cholesterol(p<0.05). From these results, it is suggested that the intakes of micro nutrients such as vitamin $B_1$, vitamin $B_2$, vitamin C have relation with cardiovascular function in female college students. However, further systematic research is needed to investigate the functions of micro nutrients in healthy persons for prevention of chronic diseases.

Background and Aims: Dansamtongmek-tang (DSTMT) and Dansamsengmek-san (DSSMS) have been used for many years as therapeutic agents for the acute stage of cerebrovascular disease, hypertension and hyperlipidemia in Oriental medicine, but the effects of DSTMT and DSSMS on hyperlipidemia and safety for cell damage are not yet well-known. This study was done to investigate the effects of DSTMT and DSSMS on hyperlipidemia. Methods: In vivo test: after administering DSTMT and DSSMS to SHR and ICR occurred hyperlipidemia for 3 weeks, we analyzed body weight, cholesterol levels. TG, HDL-chol, LDL-chol, LDH in plasma, brain, liver and kidney tissue, and DNA by RT-PCR. In vitro test: after administering DSTMT and DSSMS to human hepatocellular carcinoma in hypoxia, we observed cell cohesion by light microscope, analyzed the inflow of Ca2+ by confocal laser scanning microscope and DNA by RT-PCR. Results: DSTMT significantly decreased the levels of triglyceride and increased the levels of HDL-cholesterol in SHR, and significantly decreased the levels of LDL-cholesterol and body weight and increased the levels of HDL-cholesterol in ICR. DSSMS significantly decreased body weight, total cholesterol levels, LDL-cholesterol, LDH and cardiac risk factor (CRE) in SHR and significantly decreased the levels of total cholesterol, triglyceride, LDL-cholesterol, LDH and CRF in ICR. DSTMT had an effect on protecting cells from damage by inhibiting production of p53 mRNA, and in DSSMS, by inhibiting production of p53 mRNA and p21 mRNA after hypoxia. DSTMT effectively blocked off Ca2+ at low density, but DSSMS effectively blocked off Ca2+ at high density. Both DSTMT and DSSMS had an effect on inhibiting lipid metabolism by blocking off production of apo B mRNA. Conclusions: These results suggest that DSTMT and DSSMS might be usefully applied for treatment of hyperlipidemia and suppression of brain damage.

The study investigated the serum lipid metabolism and enzyme activities of Korean teas for their preventative activity against chronic disease and obesity. Male Sprague-Dawley rats were raised for 8 weeks on four experimental diets: normal diet, hyperlipidemic diet, and hyperlipidemic diet to which green and black teas (2% each) were added. Various biological actions, including lipid metabolism and enzyme activities of the serum, were investigated. Diet-induced, hyperlipidemic rats fed with green and black teas, showed significant decrease in food efficiency ratio, triglyceride, total lipid, and phospholipid compared to control, i.e. the normal and diet-induced, hyperlipidemic rats. Total cholesterol, LDL-cholesterol, Al(atherogenic index), LHR, VLDL-cholesterol, ester-cholesterol, and free-cholesterol also showed a significant decrease. However, there was no significant difference between the tea-fed, diet-induced, hyperlipidemic dieted groups. HDL-cholesterol concentration was increased significantly in the tea-dieted and normal groups compared to the control. There was a little difference in lipase activity between the normal and control groups, although green and black tea-dieted experimental groups were both increased compared to the control. The contents of total lipid, triglycerides, and total cholesterol were decreased in the normal and experimental groups compared to the control. The GOT, GPT, ALP and LDH serum enzyme activities of the experimental groups were significantly reduced compared to those of the control groups.

Mugwort has been used as a Korean folk medicine in treating liver diseases acting as an analgesics, sedative, diuresis, choleretics. This study was perfomed to evaluate the effect of mugwort extracts on the changes of enzyme activities, lipid accumulation of the serum and liver, when hepatotoxicity was induced by benzo(a)pyrene. The results are as follows: 1. Mugwort water extract administration prevented the increase of serum and liver AST, ALT, LDH, ${\gamma}$-GTP, liver ALP activities and bilirubin content caused by B(a)P injection. 2. The increase of serum and liver ALT, LDH, ${\gamma}$-GTP, serum AST activities and liver bilirubin contents in B(a)P treated group were decreased by mugwort methanol extract treatment. 3. Serum and liver total cholesterol, phospholipid, triglyceride level and serum HDL-cholesterol level were increased by B(a)P treatment. After combined treatment of mugwort water and methanul extracts, these lipid content were significantly decreased. 4. The hepatotropic effect of mugwort water extract and after-treatment against B(a)P induced hepatotoxicity was superior to that of methanol extract and pretreatment.

Based on equal number of cells, supplementation of 10$^{-6}$ M cadimium highly simulated the intracellular amylase. GCT, LDH as well as the glucose and erea content of E carotovora var, carotovaro cells. This was coupled with initiation of highly active GOT, CPK as well as accumulation of cholesterol in the cells. Lanthanum was less active and unable to initiate COT or CPK. Nickel was almost without effect though reduced LDH activity without initiating either enzyme or cholesterol production. Similar stiulations and/or initiations were observed, though to variable extents, when the same concentration of the three elements were supplied to E. carotovora var, citullis or E. toxica. The highest yield of amylase, GPT, GGT or glucose was obtained when E. carotovora var. carotovora was supplemented with Cd + Ni. The highest urea level was recorded in Erwinia carotovara var, cirullis, amended with Cd + La.
