This study was designed to examine effects of the various levels of sardine and safflower oil mix on lipid contents of serveral tissues in dietary hyperlipidemic rats. Experimental oils were 16% butter(control group), 8% butter+8% olive oil(group 2), 8% butter+8% sardine oil(group 3), 8% butter+6% sardine oil+2% safflower oil(group 4), 8% butter+4% sardine oil+4% safflower oil(group 5), 8% butter+2% sardine oil+6% safflower oil(group 6) and 8% butter+8% safflower oil(group 7). The diet administered to the male rats of Sprague-Dawley were fed for 4 weeks. In the fatty aicd composition of brain phospholipid, n-3 EPA and DHA contents were increased, and DHA content was remarkably high in the phosphatidylethanolamine(PE) component. Arachidonic acid content were high in the cardiolipin component. In the fatty acid composition of heart phospholipid, PUFA contents were highest in the group 5 and DHA content was higher in the groups 4 and 5, particularly. Fatty acid composition of spleen lipid showed that n-3 EPA and DHA contents were higher in the group 3 than in the other groups.

This study investigated the effects of lipid metabolism on male Sprague Dawley rats given porphyran diet extracted from Porphyra yezoensis for 4 weeks. We divided into 5 diet groups which were normal diet, control diet fed high fat, cholesterol and sodium cholate, control and 1% porphyran diet (1% PD), control and 5% porphyran diet (5% PD), control and 10% of porphyran diet (10% PD). Feed intake and weight gain were not significantly different between control and porphyran diet. Serum triglyceride, total cholesterol and LDL-cholesterol contents were significantly (p<0.05) lower in porphyran diet groups than control group. However, serum HDL-cholesterol contents increased by the addition of porphyran in experimental diet. Hepatic triglyceride and total cholesterol concentrations were proportionally decreased by the addition of porphyran in control diet compared to control diet. A number of lipid particles were shown in liver tissue of control group and the same appearance was shown in the group fed with 1% porphyran diet, whereas lipid particles was reduced in the group fed with 5% and 10% porphyran diet compared to control group. Especially, liver tissue of 10% porphyran diet group was shown similar appearance to normal diet group. These results indicated that supplementation of porphyran in hyperlipidemic rats has an effect on the improvement of serum lipids.

The aim of the present study was to investigate the effect of duck extract on lipids. Rats in the experimental group were orally administered with duck extract for four weeks. The half of the supplementation was composed of duck meat and the other of the supplementation was composed of oriental herbs. Weight gain, diet intake, and food efficiency ratio were compared between control and experimental groups. Organ weight, lengths of small/large intestines, and the following plasma biochemical parameters were also measured: hemoglobin, hemoglobin, GOT, GPT, blood glucose concentration, lipids of plasma, liver, feces. Spleen index (weight/100 g body weight) of the rats in the experimental group was significantly higher than those in the control group due to increase in fat intake from the supplementation of duck meat. The large intestines of the rats in the experimental group was significantly larger due to the supplementation with dietary fiber derived from herbs in the extract. There were significant higher levels of plasma hematocrit, GOT, total cholesterol, and HDL-cholesterol in the rats of the experimental group. From the results, although duck meat is a source of animal food, the fat profile of duck extract, such as the ratio of polyunsaturated fatty acids to saturated fatty acids appears to be beneficial to human health. These findings suggest a possible anti-hyperlipidemic effect of duck extract. (Korean J Nutrition 36(1): 3∼8, 2003)

Purpose: Atorvastatin, a HMG-CoA reductase inhibitor is widely prescribed in hyperlipidemic patients and telmisartan, an angiotensin receptor blocker is frequently used in the treatment of hypertension. Both drugs are substrates of organic anion transporting polypeptide (OATP) expressed in basolateral membrane in the liver, and undergo high first pass metabolism. Therefore, OATP-mediated hepatic uptake is important for disposition and metabolism of these drugs. The present study was designed to investigate the pharmacokinetic interactions between atorvastatin and telmisartan in rats. Method: Young adult SD rats were divided into three groups (n=6, each) and atorvastatin (10 mg/kg) and telmisartan (4 mg/kg) were orally given alone and together. Heparinized blood was serially taken and plasma concentrations of both drugs were measured using HPLC-MS/MS. Pharmacokinetic parameters of two drugs were calculated. Results: No significant pharmacokinetic change was found except a delay of time to peak of telmisartan when administered with atorvastatin. Each drug at the present dosage seemed to be insufficient to alter the pharmacokinetic parameters of its counterpart drug. Conclusion: Conclusively, co-administration of atorvastatin and telmisartan may lead to negligible clinical consequences.

Objectives : This experiment was performed to determine the effects of the Jeseubsungi-tang(JSSGT) on hyperlipidemia-induced by hypercholesterolemic diet in mice. Methods : C57BL/6 mice were sensitized with a hypercholesterolemic diet for 6 weeks. Experimental group was treated with $150mg/d{\ell}$ concentrations of JSSGT for 4 weeks (once a day). Results: JSSGT-treated mice showed a body weight decrease compared to normal group. JSSGT-treated mice showed a significant decrease in cholesterol, total cholesterol, triglyceride, ALT and LDL-cholesterol levels compared to hyperlipidemia-induced control group. However, HDL-cholesterol levels in JSSGT-treated group significantly increased compared to the hyperlipidemia-induced control group. Conclusion : These results suggest that JSSGT is effective in treating hyperlipidemia. Because only hyperlipidemic mice were studied, further research is needed.

Objective : Yegangji-tang (YJT) is noted in China as effective medicine for hyperlipidemia. This experiment was performed to determine the effects of Yegangji-tang (銳降脂湯: YJT) on antioxidant activity and hyperlipidemia induced by hypercholesterolemic diet in mice. Methods : We observed three experimental groups: normal, control, and treatment. Rats were provided a normal diet in the normal group, and the other groups were provided a hypercholesterolemic diet to induce hyperlipidemia. After 2 weeks, YJT was treated to the treatment group. We observed the change of body and liver weight, change of serum total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides, lipid peroxidation and antioxidant activity of liver tissue, cholesterol gene revelation control efficiency, and histologic change of liver and abdominal aorta. Results : Total cholesterol, LDL cholesterol and triglycerides decreased significantly with YJT, whereas HDL cholesterol increased significantly. Lipid peroxidation decreased and antioxidant activity of the liver increased significantly. Gene revelation of ACAT and HMG-CoA reductase in hepatic tissue decreased significantly with YJT. We also found that tissue defects of the liver and abdominal aorta were controlled by YJT on histologic study. Conclusion : These results suggest that YJT might be effective in treatment and prevention of hyperlipidemia.
