  • This study was conducted to investigate whether dietary factors, normal fat and genistein leads to beneficial improvement of lipid metabolism and oxidative stress in adult hyperlipidemic male rats. Seven wk-old male SD rats were fed high fat diet (15% fat, 1% cholesterol) for 4 wks for induction of hyperlipidemic model rat. Weight-matched rats were then assigned to four groups according to dietary fat level (7% or 15% fat) and genistein contents (0 or 320 mg/kg diet). Food intake was significantly decreased by both high fat intake and genistein supplementation compared with normal fat intake and genistein no supplementaion. But weight gain was significantly decreased by genistein supplementation in normal fat intake compared with the other groups. Total lipid, total cholesterol and triglyceride in serum and liver were significantly decreased by normal fat intake compared with high fat intake. But total cholesterol in liver was significantly increased by genistein supplementation in both high fat and normal fat intake. TBARS in serum and liver was less produced by normal fat intake compared with high fat intake but TBARS in liver was significantly increased by genistein supplementation compared with genistein no supplementation in normal fat intake. Glutathione reductase activity in erythrocytes was significantly reduced by genistein supplementation in normal fat intake compared with the other groups. Glutathione peroxidase and glutathione reductase activities in liver were significantly inhibited by normal fat intake compared with high fat intake. Catalase activity in liver was significantly increased by genistein supplementation compared with genistein no supplementation in high fat intake. Nitrite was significantly decreased by normal fat intake compared with high fat intake. These results suggest that normal fat intake has the treatment effect against risk factors related with cardiovascular disease by reducing lipid profiles, lipid peroxidation. And genistein shows action as a antioxidant replacing antioxidant enzymes but also may act as prooxidant causing the production of TBARS.

  • The plants, Trianthema decandra and Glinus oppositifolius are commonly used by tribal people in India for the treatment of liver diseases. Hepatoprotective activity of methanol extracts of Glinus oppositifolius and Trianthema decandra at the dose of 250 and 500 mg/kg body weight administered orally was evaluated against paracetamol induced liver damage in rats. Biochemical parameters such as serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase, serum alkaline phosphatase, bilirubin, total serum protein, lipid peroxide and glutathione content of the liver were estimated to determine liver function and metabolism. From the biochemical observations, it was concluded that methanol extracts of Glinus oppositifolius and Trianthema decandra significantly restored the altered biochemical parameters towards normal condition in paracetamol induced liver damage.

  • The cholesterol and fatty acid levels in serum and liver were compared in 4-week-old Sprague-Dawley male fed by addition of polymannuronate (M, 5.0%), polyguluronate (G, 5.0%), and polymannuronate and polyguluronate (MG, 2.5% to each) with by addition of cholesterol (1.0%). Feed efficiency by the addition of M, MG, and G was lower than cholesterol fed group (p<0.01). The liver weights were less in M, MG, and G fed groups than in cholesterol fed group (p<0.01). Triglyceride levels in serum and liver were 58.2∼77.4% and 51.5∼65.5% lower in M, G and MG fed groups than cholesterol fed group, respectively. Total-, LDL-, and free-cholesterol levels in serum and liver in M, MG, and G fed group were significantly lower than cholesterol fed group. The cholesterol levels were the most reduced in M fed group. However, HDL- cholesterol level in serum was increased in M, MG, and G fed group (p<0.01). The of polyene levels were 47% higher in serum and 76% in liver in M fed group than in cholesterol fed group. The activities of GOT and GPT were lower in M, MG, and G fed group than in cholesterol fed group (p<0.01). Above the results demonstrate that supplementation of low molecular polymannuronate in diets improve physiologically lipid composition in serum and liver.

  • This study was undertaken to investigate the effect of Cassia tora ethanol extract on the lipid levels in serum and liver of rats fed high cholesterol diet. Experimental rats were divided into the following 4 groups: normal diet group, high cholesterol diet group, high choleslerol-0.25% C. tora ethanol extract group and high cholesterol-0.5% C. tora ethanol extract group. After 4 weeks, rats were sacrificed and analyzed the serum lipid profiles, activities of serum alanine aminotransferase (AST), aspartate aminotransferase (ALT), hepatic glucose-6-phosphate dehydrogenase (G6PDH) and malic enzyme (ME). It was also determined the contents of total cholesterol, triglyceride and thiobarbituric acid reactive substances (TBARS) in liver. There was no difference in weight gains between experimental groups. The concentrations of serum total cholesterol, free cholesterol, triglyceride and free fatty acid were tended to be decreased in C. tora groups compared with control group. HDL-cholesterol concentration was significantly decreased in high cholesterol diet group and slightly increased by C. tora ethanol extract feeding. The contents of liver cholesterol and triglyceride were higher in high cholesterol diet group than normal group, but significantly decreased by feeding of C. tora ethanol extract. Supplementation of 0.5% C. tora extract decreased significantly the activities of hepatic G6PDH and ME. Activities of serum AST, ALT and contents of liver TBARS were tended to be increased with high cholesterol diet and reduced by C. tora ethanol extract supplementation but had not significance. These results suggest that C. tora ethanol extract may exert a lipid lowering effect in serum and liver of rats.

  • Male Sprageu-Dawely rats fed a cholesterol diet (Control group) or cholesterol diet supplemented with the water-soluble extract of stem bark from Cudrania tricuspidata(CTSB group) at the level of 0.5% for 2 weeks. Concentration of triglyceride in serum of CTSB group was significantly lower than that of control group. However, the other lipids concentrations of liver and serum, body weight gain, and food intake did not show significant difference between CTSB group and control group. Antioxidative activities of water-soluble extract from stem bark of Cudrania tricuspidata on the lipid peroxidation in rat were also studied in vivo by measuring the formation of thiobarbituric acid reactive substance(TBARS). Concentration of TBATS in the liver homogenates of CTSB group was significantly higher than that in control group. Nonheme iron concentration was significantly increased in the liver of CTSB group compared to control group. suggested that enhanced nonheme irom was associated with enhanced peroxidation of liver in CTSB group. These results suggested that water soluble extract from stem bark of Cudrania tricuspidata exert the hypotriglycerolemic effect and might amplify the lipid peroxidation of tissues in cholesterol fed rats.

  • This study was carried out to investigate the effects of rice germ oil supplement on the lipid metabolism of insulin-dependent diabetic mice. Streptozotocin-induced diabetic mice were fed three kinds of experimental diets with 20% lipid, composed of 20% lard (L) : 10% lard and 10% rice germ oil (LRGO) ; and 20% rice germ oil (RBO), respectively, for 7 weeks. Diet intake, body weight, organ weight and lipid levels of serum, liver and feces were measured. There was no significant difference in diet intake, body weight and organ weight among the experimental groups. But the concentrations of serum triglyceride in the LRGO and RGO groups, and of serum total cholesterol in the RGO group, were significantly lower than those of the L group fed the 20% lard diet. The levels of hepatic total lipid of the RGO group, and of hepatic total cholesterol of the LRGO and RGO groups were significantly lower than those of the L group. The contents of total lipid and total cholesterol excreted in the feces of the LRGO and RGO groups were higher than those of the L group. These results suggest that rice germ oil can reduce the levels of total cholesterol concentrations in the serum or livers of insulin-dependent diabetic mice, and that the hypolipidemic effect of rice germ oil may be due to increasing fecal lipid excretion and decreasing lipid absorptivity.

  • Young male rats were fed for 10 and 20 days on different low-fat experimental diets ; 4% lard + 4% soybean oil, 4% sardine oil + 4% lard, 4% sardine oil with vitamin E+ 4% lard, 4% sardine oil with vitamin E+ 4% soybean oil. Lipid peroxide levels in liver were significantly higher in the sardine oil groups but the addition of vitamin Ehad no effects on the lipid peroxide values. Serum total cholesterol showed no significant difference among the groups but HDL-cholesterol in serum was increased in the sardine oil groups. However, the contents of serum triglyceride and phospholipid were unaffected by the replacement with sardine oil.

  • This study was conducted to investigate the supplementary effects of Lentinus edodes on blood pressure and blood lipid levels in the Hypertensive Rat. We supplied 3 kinds of experimental diets (Control; CO, cap of Lentinus edodes; LC, and stipe of Lentinus edodes; LS) to spontaneously hypertensive rats (SHR) for 8 weeks. Diet intake, body weight, organ weights, and serum lipid levels were measured. There was no significant difference in diet intake, and body, liver and epididymal fat pad weights among experimental groups. The levels of systolic and diastolic blood pressure were significantly lower in LC and LS groups than CO group. The concentrations of serum total cholesterol were lower in LC and LS groups than CO group. These results suggested that Lentinus edodes decrease blood pressure levels and serum total cholesterol concentration in the spontaneously hypertensive rats. But these effects of Lentinus edodes didn't show any significant difference between animals fed cap and stipe of this mushroom.
