Objective : This study was to elucidate the effects of Hyunsamkabhangbang (HSK) on the hyperthyroidism induced by sodium levothyroxine. Method : Sprague-Dawley rats were separated into five groups. Except the normal group, the other four groups were treated with sodium levothyroxine 160${\mu}g/kg/day$ for 5 days by oral administration. Among the four groups, all except one (as control) were treated with various concentrations of HSK (0.5, 1.0, 2.0 g/kg/days) for 3 days separately. T3-uptake, T3, T4, TSH, total cholesterol, free fatty acid, ${\beta}$-lipoprotein, glucose, ALP, AST, ALT change in the serum and body weight of rats were measured after medication of solid extract of HSK. Results : HSK decreased significantly serum T3, T4, T3-uptake, ALP, free fatty acid and glucose level in a dose-dependent manner compared with control. HSK increased significantly serum TSH and total cholesterol level and body weight in a dose-dependent manner compared with control. HSK also increased serum ${\beta}$-lipoprotein level compared with control, but not statistically meaningfully. HSK increased significantly serum AST and ALT level compared with control, but relationship to hyperthyroidism is not found. Conclusions : From these results, it could be concluded that HSK lowers excess thyroid hormone and increased metabolism, resulting in improvement of hyperthyroid state.

The variation in the enzyme activities of human liver usually represents the particular physiological conditions of each individuals. Thus, we investigated the variation in the activities of SOD, HR and LPO of (1) non-exposed workers (56 subjects), and (2) exposed workers to DMF (43 subjects) in synthetic leather process. Serum levels of enzyme activities of exposed workers (AST:$30.26{\pm}20.041$U/L, ALT:$32.72{\pm}23.393$U/L, GGT:$28.47{\pm}18.635$ U/L, ALP:$81.77{\pm}34.879$ U/L)were slightly higher than those in nonexposed workers (AST:$24.00{\pm}9.441$ U/L, ALT:$23.89{\pm}18.305$U/L, GGT:$21.95{\pm}17.970$U/L, ALP:$70.84{\pm}24.678$U/L), but only the level of ALT was statistically significant (p< 0.05). Serum levels of LDH, TRF and CHOL in non-exposed workers were slightly higher than those of exposed workers. However, they were not statistically significant (p > 0.05). Serum levels of HR and LPO of the exposed workers appeared to be reduced, but not those of the non-exposed workers. The SOD activities of exposed workers were also slightly higher than those of non-exposed workers, but the results were not statistically significant (p > 0.05). The level of HR was increased with age, but the SOD level was not. These results suggest that the intermittent exposure to DMF at time-weighted average (TWA) level (10 ppm/$m^3$) has affected on the activities of enzymes such as AST, ALT, TRF, but not on the generation of HR, activity of SOD. However, if high dose of DMF was used, there would be severe effects for the generation of HR and LPO.

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.

The present study was carried out to investigate the effects of magnesium supplement levels and periods on lipid metabolism in male Sprague-Dawley rats given low protein and magnesium deficient diets. The effect of magnesium supplement levels and periods on lipid metabolism in rats given a low protein and magnesium deficient diet for 2 weeks were investigated. Serum total lipid and triglyceride contents were significantly lower in magnesium supplement group compared with magnesium deficient group. Serum HDL-cholesterol/total cholesterol ratio was significantly increased as magnesium supplement level was increased. Liver total lipid, triglyceride, total cholesterol and phospholipid contents were significantly lower in magnesium supplement group than those in magnesium deficient group. Serum ALP, GOT and GPT activities were significantly decreased in magnesium supplement group compared with magnesium deficient group. In summary, the effect of magnesium supplement on lipid metabolism and enzyme activities were significant and we can see that magnesium supplement level propered to be requirement level(400 mg/kg diet)in the other cases except serum lipid contents.

To evaluate the effect of cyclohexane(CH) treatment on the serum levels of glutathion S-transferase(GST) activity in liver damaged animals, damaged liver was induced with pretreatment of 50% $CCl_4$ dissolved in olive oil (0.1 m1/100g body weight) intraperitoneally 17 times every other day. To $CCl_4$-treated rats, CH (1.56 g/kg body weight, i.p) was injected once and then the animals were sacrificed at 4 hours after injection of CH. The $CCl_4$-treated animals were identified as severe liver damage on the basis of liver functional findings, 1,e, increased serum levels of alanine aminotransferase(ALT), alkaline phosphate(ALP) and xanthine oxidase(XO) activities. On the other hand, $CCl_4$-treated animals injected with CH once($CCl_4$-pretreated animals) showed more decreased serum levels of ALT and XO, and more increased those of ALP rather than $CCl_4$-treated animals. In case of comparing the GST with ALT activity in liver, both $CCl_4$-treated and pretreated animals showed similar changing pattern of enzyme actvity. Especially $CCl_4$-pretreated animals showed significantly increased serum level of GST actvity compared with the $CCl_4$-treated those, whereas those of ALT showed reversed tendency. In aspects of GST enzyme kinetics, $CCl_4$-pretreated animals showed higher Vmax of liver GST enzyme than $CCl_4$-treated animals. In conclusion, injection of CH to the liver damaged rats led to enhanced liver damage and more increased activity of serum GST which may be chiefly caused by the enzyme induction.

To investigate the effects of yellow soybean powder on serum lipid level and enzyme activities, male Sprague-Dawley(SD) rats were given hyperlipidemic diets for 6 weeks. Rats(n=8) were divided into three groups consisting the normal group(N), hyperlipidemic diets group(C) and hyperlipidemic diets and yellow soybean powder group(YSP). YSP group lowered triglyceride, total lipid, phospholpid, ester-cholesterol and free-cholesterl than control group. YSP group lowered total-cholesterol, VLDL-cholesterol and LDL-cholesterol but increased HDL-cholesterol of the serum compared to the control group. Athergenic Index(AI) and LHR(LDL-cholesterol/HDL-cholesterol ratio) of YSP group was decreased by control group (p<0.05). On the other hand, glutamic oxaloacetate transaminase(GOT), glutamic pyruvate transaminase (GTP), lactate dehydrogenase(LDHase) and alkaline phosphatase(ALP) enzymes activities were decreased by hyperlipidemic diets group (C). These results suggest that yellow soybean powder fed a lipid lowering effect in serum of rats.

This study was performed to evaluate the effect of sodium cholride supplementation on bone metabolism in female rats consuming a low calcium diet. Twenty five female rats were divided into three dietary groups (control Na : 0.1038%, 1% Na : 1.036%, 2% Na : 2.072%). All experimental diets contained 0.27% Ca and were fed to rats with deionized water for 7 weeks. Bone mineral density(BMD) and bone mineral content(BMC) of total body, spine and femur were measured using energy x-ray absorptiometry(DEXA) by small animal software. Then Ca efficiency was calculated from BMD and BMC. Serum Ca, P, Na and urine Ca, P, Na were determined. Urinary pyridinoline, serum ALP were measured to monitor bone resorption. Following 7 weeks, sodium cholride supplemented groups had higher urinary Ca excreteion, urinary pyridinoline, crosslinks value and serum ALP. There was no significant difference in case of serum Ca among all groups. Sodium chloride supplemnted groups had lower Ca effciency of total, spine and femur BMD and BMC than that of control group. In conclusion high salt intake not only increases urinary Ca excretion as urinary Na excretion does but also increase bone resorption and decrease Ca efficiency of each bone. It is been suggested that high salt intake may be harmful for bone maintenance. Therfore, the decrease of salt intake to the level of recommendation would be desirable.
