The hypoglycemic effect of fractions of methanol extract of Cassia tora was investigated in diabetic rats. Sprague-Dawley male rats weighing 180∼230 g were divided into 6 groups. Diabetes was induced in the male rats by intravenous injection of streptozotocin at a dose of 45 mg/kg dissolved in citrate buffer (pH 4.5). The diabetic animals then had plasma glucose concentration of above 300 mg/㎗. Fractions of methanol extract of Cassia tora were administered orally into the diabetic rats for 14 days after streptozotocin injection. The food intake and body weight gain were monitored and plasma levels of glucose, triglyceride, free fatty acid, HDL-cholesterol, cholesterol and ALT activity were determined. Levels of glycogen, cholesterol and triglyceride in liver were analysed. Weights of liver and kidney were lighter in all the fraction-administered groups than streptozotocin-control group. Plasma glucose level was significantly decreased by the administration of butanol fraction at 14 days. Plasma triglyceride levels were lower in chloroform, butanol and H$_2$O fraction-administered groups compared to streptozotocin-control group. Plasma cholesterol and HDL-cholesterol levels were not significantly different in all groups. Administrations of each of the four fractions have decreased plasma free fatty acid level, ALT activity and liver triglyceride levels in the diabetic rats. Liver glycogen levels in chloroform, butanol and H$_2$O fraction-administered groups were higher than streptozotocin-control group. It is suggested from the results that butanol fraction of methanol extract of Cassia tora may contain the antihyperglycemic compounds.

The effects of the essential oil fraction and the fatty acid-fraction of the panax Ginseng on the various lipids (total cholesterol, phospholipid, triglyceride) in serum and liver tissues of the white rats were examined and observed after the administration of the fractions for eight weeks with the following results: 1. Serum total cholesterol level was slightly decreased in the group after giving the essential oil fraction four weeks, whereas the effects in the group after giving itfor eight weeks were increased. Phospholipid level was slightly elevated both in four weeks and in eight weeks, while triglyceride level was elevated after four weeks, whereas it showed nochange at all after eight weeks. In the liver tissues, the cholesterol content was slightly decreased after four weeks and remarkably decreased after the administration for eight week. Phospholipid increased after four week administration and then rather decreased after the eight week administration, while the triglyceride content decreased both in four weeks and in eight weeks. 2. In the group giving the fatty acid-fraction, serum total cholesterol level decreased after the four week administration and then returned to the pre-experiment mean after the eight-week administration, while phospholipid level increased after the four-week administration and then returned to the pre experiment mean. Triglyceride level increased after four week administration of the fraction and rather then decreased after eight weeks. In the liver tissues, total cholesterol content decreased both after four weeks and after eight weeks, while phospholipid level also decreased from four weeks through eight weeks, whereas triglyceride level increased after four weeks, and showed rather decreasing tendency after the eight-week administration.

Hypoglycemic effect of Tabebuia avellandae was investigated in the streptozotocin(STZ)-induced diabetic rats. Diabetes was induced in male Sprague-Dawley rats by injections of STZ (45 mg/kg, i.v.). Rats weighing 200-250 g were divided into 6 groups: normal, STZ-control, hexane fr., CHCl$_3$fr., BuOH fr. and $H_2O$ fr. group. Normal and STZ-control rats received 3% Tween 80 only. Four groups of diabetic rats were administered orally at doses of 100, 400, 300 and 400 mg/kg/day of hexane, CHC1$_3$, BuOH and $H_2O$ fr. respectively. Fractions were administered orally to the rats for 7 days after STZ injection. All rats were anesthetized with ether, blood samples were taken by cardiac puncture for clinical chemistry and the rats were killed by exsanguination. Liver, kidney, heart and spleen were removed, weighed and analyzed. We measured glucose, protein, cholesterol and triglyceride levels in the plasma and glycogen, cholesterol and triglyceride levels in liver. The extent of blood glucose decrement in rats administered $H_2O$ fraction was greater than that in the STZ-control rats. The serum cholesterol and triglyceride levels were significantly lowered by administration of $H_2O$ fraction compared with those of STZ-control group. Treatment of rats with Tabebuia avellandae fractions caused decreases in STZ-induced elevation of cholesterol and triglyceride. Liver triglyceride level was significantly lowered hexane and BuOH fraction group compared with STZ-control group. These results suggest that $H_2O$ fraction of Tabebuia avellandae has the hypoglycemic action against STZ-induced diabetic rats.

Among the many deleterious effects of cardiopulmonary bypass[CPB], deterioration of plasma lipoprotein is a significant problem. Break-down of lipoprotein releases free fatty acids into the systemic circulation which, in turn, can cause microembolism. This study conducted on 30 patients undergoing CPB, was designed to elucidate the changes of plasma lipoproteins during and after CPB. Blood samples were taken at pre-CPB, on-CPB 30 minutes and 60 minutes, postoperative 1st, 3rd, 7th days. The levels of total cholesterol and triglyceride were measured and lipoprotein was subdivided into three kinds on electrophoresis. During CPB, the amounts of plasma total cholesterol and triglyceride decreased significantly and were recovered to pre-CPB levels after postoperative third day. There was no significant correlation between the duration and the severity of decrease in plasma total cholesterol and triglyceride levels. During CPB, the fraction of VLDL decreased and that of LDL increased. After cessation of CPB, the fraction of LDL decreased and that of HDL increased. After postoperative 1st day, the fraction of HDL decreased and that of LDL increased.

The berries of Schisandra chinensis (Schisandra fructus) are given the name Omiza in Korean (五味子), which translates as "five flavor fruit" because they possess all five basic flavors in Korean traditional herbal medicine: salty, sweet, sour, pungent (spicy), and bitter. It is used as a remedy for many ailments: to resist infections, increase skin health, and cure insomnia, coughing, and thirst. This study was designed to investigate the effects of Schisandra fructus butanol fraction (SFB) on serum lipid levels in hyperlipidemic mice. In this experiment, effects on total cholesterol, HDL-cholesterol, and triglyceride in serum were measured. In our results, SFB did not affect weight gain in hyperlipidemic mice. Oral administration of SFB lowered levels of total cholesterol and triglyceride, which were elevated by induction of hyperlipidemia. Finally, administration of SFB regulated changes in gene expression which were related to cell growth and differentiation.

Antihyperlipidemic and antihyperglycemic effects of Red Ginseng (RG, steamed and dried root of Panax ginseng C.A.Meyer, family Araliaceae), major component of which is ginsenoside Rg3, and Bifidodoterium-fermented RG (FRG), major component of which is ginsenoside Rh2, were investigated. Orally administered RG and FRG potently reduced the serum triglyceride levels in com-oil-induced hypertriglycemidemic mice as well as total cholesterol and triglyceride levels in Triton WR-1339-induced hyperlipidemic mice. Of the saponin and polysaccharide fractions of RG and FRG, the polysaccharide fraction inhibited postprandial blood glucose elevation of maltose- or starch-loaded mice and reduced the blood triglyceride levels in com-oil-induced hypertriglycemidemic mice. The saponin fraction and its ginsenosides Rg3 and Rh2 reduced blood triglyceride and total cholesterol levels in Triton WR1339-induced hyperlipidemic mice. The inhibitory effect of FRG and its main constituents against hyperlipidemia and hyperglycemia in mice were more potent than those of RG. These findings suggest that hypolipidemic and hypoglycemic effects of RG can be enforced by Bifidus fermentation and FRG may improve hyperlipidemia and hyperglycemia.
