Hepatoprotective activities of 26 traditional Korean herbal prescriptions described in Donghibogam were evaluated in vivo and in vitro screening system. Twenty one prescriptions appeared to be active. Six prescriptions among them showed highly significant hepatoprotective activities; Shihogyegy-Tang(柴胡桂枝湯), Soshiho-Tang(小柴胡湯), Shiho plus Younggolmoryo-Tang(柴胡加龍骨牡蠣湯), Yinjinho-Tang(茵蔯蒿湯), Yinsam-Tang(人蔘湯) and Shashim-Tang(瀉心湯). Shihogyegy-Tang was most active. They reduced the release of transaminases from dissociated hepatocytes by thioacetamide, and serum transaminases and alkaline phosphatase activities of rat with carbontetrachloride-induced hepatitis. They inhibited significantly lipid peroxidation and cellular fatty change of liver by carbontetrachloride.

To investigate the effect of dietary Ca levels on metabolic changes of Ca and skeleton in postmenopausal women, 10-month-old ovariectomized female rats were compared with 2 month old rats. The rats were fed either 0.2% or 1.2% Ca diets for 16 weeks. Food intake and weight gain as higher in rats fed high Ca diets and in ovariectomized rats. Apparent Ca absorption as higher, and Ca balance was lower in the low Ca groups. Vertebrae density was higher in old rats or those fed a high Ca diets. The old rats and ovariectomized rats showed decreased bone formation, increased bone resorption and kidney function deterioration resulting in increased urinary Ca excretion. Contradictory to the above observation, old rats and ovariectomized rats still showed higher bone mass and bone ash content. Therefore aging was not fully onging in 10-month-old rats. Bone weights, mineral contents, and mineral/wt ratio were lower in ovariectomized rats. Dietary Ca level did not affect urinary Ca excretion, urinary protein excretion, GFR, serum alkaline phosphatase, or urinary hydroxyporline excretion. This means that dietary Ca level did not influence kidney function or bone turnover. However Ca content and the ash content of femur, 4th vertebra, and scapula were increased in high Ca groups. Therefore, it is considered that decreased bone formation and accelerated bone resorption may account for the increased osteoporotic risk in women in menopause after middle age. However, Ca metabolism can be improved and bone components can be maintained if Ca is supplemented.

The hypoglycemic and metabolic effects of Commelina communis L. extract were investigated in alloxan-diabetic rats. The increased blood glucose level in the diabetic rats was significantly lowered and the loss of body weight in the diabetic rats was recovered with the treatments of the crude extract. Administration of the extract elicited the significant increase of glucose-6-phosphate dehydrogenase activity and liver weight which were decreased in the alloxan-treated rat serum and liver. On the other hand, the kidney weight and glucose-6-phosphate dehydrogenase activity were increased in the alloxan treated rat kidney and were potentiated by the treatment of the extract. In both liver and kidney, together with serum, alkaline phosphatase and ATPase activities were increased in the alloxan diabetic rats and were not recovered, rather potentiated by the administration of the extract.

Background : Osteopenia has been recognized as one of potential complication of chronic liver diseases. Its correlation with hepatits B virus(HBV) carrier, however, has not been reported. Thus this study was aimed to clarify the relationship between the osteopenia and HBV carrier. Methods : Bone densities in 192 HBV carrier women and 200 healthy women were measured; the lumbar spine and three sites of the proximal femur(neck, Ward's triangle, greater trochanter) by dual-photon absorptiometry. And liver function tests(AST, ALT, Albumin, GGT, ALP) were also performed. Results : Bone densities at the four sites measured, were significantly correlated with one another(r=0.34 to 0.99, P<0.01). Compared with control group, HBV carriers had significant decreases in bone densities of femur(P<0.05), particularly marked at Ward's triangle. A negative correlations between bone densities and serum total alkaline phosphatase were also found(r=-0.44, P<0.01). Conclusions : Osteopenia was more prevalent in HBV carrier, particularly in the groups before-fifties. Serum total alkaline phosphatase was higher in those with reduced bone densities Thus measurement of bone densities seems to be necessary in female HBV carriers.

Objectives : This study was carried out to determine the effects of Gamidokwalgisaeng-tang(GDS) oral administration and electro-acupuncture at $BL_{52}$ & $GB_{39}$ on the postmenopausal osteoporosis. Methods: In order to study the effects of the Gamidokwalgisaeng-tang(GDS) oral administration and electro-acupuncture at $BL_{52}$, $GB_{39}$ on osteoporotic rats induced by ovariectomy, body weight, femur weight, uterine weight, serum level of osteocalcin, alkaline phosphatase(ALP), cholesterol, triglyceride, estradiol, androstenedione, testosterone and urinary excretions of calcium & phosphorus were measured. Results : 1. Body weight in all experimental group decreased significantly in comparison with ovariectomized group(OVX). 2. The weight of femur compared with body increased significantly in GDS oral administration and combination treatment group in comparison with ovariectomized group(OVX). 3. Uterine endometrial morphology is caused by ovariectomy and the weight of uterus decreased significantly in control and all experimental group in comparison with sham. 4. The serum level of osteocalcin decreased in all experimental group in comparison with OVX, but significantly in electro-acupuncture and combination treatment group. 5. The serum alkaline phosphatase(ALP) activity decreased in electro-acupuncture and combination treatment group in comparison with OVX, but only significantly in electro-acupuncture group. 6. The serum level of cholesterol increased significantly in OVX in comparison with sham and decreased in all experimental group in comparison with OVX, not insignificantly. The serum level of triglyceride increased in all experimental group in comparison with OVX, not insignificantly. 7. Urinary excretions of calcium and phosphorus decreased significantly in all experimental group in comparison with OVX. Conclusion : We suggest that GDS oral administration and electro-acupuncture at $BL_{52}$ & $GB_{39}$ are available for prevention and curing about the postmenopausal osteoporosis.

To study the effects of dietary protein and magnesium level on serum lipid contents and enzyme activities, male Sprague-Dawley rats were divided into six groups. Six groups of animals were fed six experimental diets different with protein(8% and 20%) and magnesium levels (Mg-free, 400mg/kg diet and 800mg/kg diet). The serum lipid contents and enzyme activities of rats fed different dietary protein and magnesium levels were examined. Serum triglyceride contents was significantly decreased as the dietary magnesium level was increased. Serum phospholipid contents was significantly higher in magnesium deficient group than those in the other groups. Serum alkaline phosphatase activity was significantly decreased in magnesium dificient group compared with other groups, but serum glutamic oxaloacetic transaminase and glutamic pyruvic transaminase activities was significantly increased in magnesium dificient group than other groups. In conclusion, serum triglyceride contents in low protein level was remarkably decreased as the dietary magnesium level was increased.

To define the risk facots of subclinical vitamin D deficiency in postmenopausal women, circulating serum 25-hydroxyvitamin D levels, known to be the indicator of vitamin D status, were measured and risk faxtors affecting it were investigated in 27 women with low 25-hydoxyvitamin d level(ie, the study group : serum 25-hydroxyvitamin D<10ng/ml) by comparing to 55 age-matched control(the control group) were analyzed. The serum level of 25-hydorxyvitamin D was analyzed by HPLC(High Pressure Liquid Chor-matography) and analyzed biochemical parameter. The following information was obtained by interviews : sociodemographic charateristics, the intake of food containing vitamin D, proxy measure of sunlight exposure(time spent outdoors), and reprocuctive histpry of the subjects. The study group had significantly lower levels of serum calcium, increased levels of iPTH and alkaline phosphatase, Among the dietary determents, energy, protein, fat, calcium, phophorus, and vitamin D intakes were lower in the study group than the normal group. The time spent outdoors in a day was not significantly different between the two groups. However, during the day, a specific time of time spent out doors between 12:00 and 14:00 was significantly lower in the study group. Logistic analysis revealed that vitamin D and calcium intake were more important affecting factors than the time spent outdoors in post menopausal women.

Earlier studies have shown that the administration of Na-alginate, a water-soluble, non absorbable acidic polysaccharide, effectively reduces the absorption of radioactive strontium, cadmium and other bivalent metals. In this study the effects of Na-alginate on the Toxicity induced by Lead and Cadmium were examined in rats and the following results were obtained. 1. The elevations of the activities of serum GOT, GPT by Pb and Cd administration in the experimental animals. However, the administration of Na-alginate significantly inhibited the elevation of serum GOT, GPT. 2. Generally serum TBA values were significantly elevated in Pb and Cd group in comparison with the control group. However, the administration of Na-alginate inhibited the elevation of serum TBA values. 3. The activity of Alkaline phosphatase was also significantly elevated in Cd group in comparison with the control group. However, the administration of Na-alginate significantly inhibited the elevation of serum alkaline phsphatase. 4. Furthermore, the activity of $\delta$-aminolevulinic acid dehydratase in red blood cells was also significantly inhibited by Pb and this inhibition was stimulated by the administration of Na-alginate. 5. The concentrations of Pb in liver and Cd in kidney were markedly increased by Pb and Cd. However, the administration of Na-alginate significantly inhibited the elevation of them.
