  • 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.

  • Background: In India smokeless tobacco users account for 25.9% of total tobacco use, Gutkha being the most common form. This study evaluated the association between serum lipid profile and Gutkha use as an early diagnostic and/or prognostic indicator for oral submucous fibrosis (OSMF) and oral cancer (Oral Ca) in non-smokers and non-alcohol consumers. Materials and Methods: A total of 163 participants were recruited from two sites in India. Participants were divided into four groups: individuals without any Gutkha chewing habit and without any oral lesions (control group), individuals with Gutkha chewing habit but without any oral lesions (GWL), patients with a confirmed clinical diagnosis of OSMF, and patients with a confirmed diagnosis of Oral Ca. Mixed linear modelling (MLM) was conducted to detect the change in mean serum lipid levels among four groups. Results: The sample consisted of 69% males and 31% females. Results of MLM show an inverse relationship between serum lipid levels in OSMF, and Oral Ca groups when compared to the control group. Conclusions: The results of our study demonstrated that GWL, OSMF and Oral Ca patients had lower serum lipid levels. Low serum lipid levels could be an indicator of initial neoplastic changes in oral cancer.

  • Many studies have shown that Letinus edodes has some effect on reducing blood pressure and lipid levels of animals with high pressure and hyperlipidemia. The cost of Letinus edodes varies depending on when it is harvested, and yet there has been no data collected on the bio-functional effects of Letinus edodes harvested at different times. This study was conducted to investigate the supplementary effects of Letinus edodes harvested at different times on blood pressure and blood lipid levels of hypertensive rats. Three kinds of experimental diets - control (CO), early harvested Lentinus deodes (EL), and late harvested Lentinus edodes (LL) - were supplied to spontaneously hypertensive rats (SHR) for eight weeks. The diet intake, body weight, organ weight, and serum lipid levels were subsequently measured. No significant difference was observed in diet intake and in the respective weights of the body, liver, and epididymal fat pad among experimental groups. The levels of systolic and disastolic blood pressure were significantly lower in the LE and LL groups than those in the CO group; and the concentration of serum total cholesterol was also lower in the LE and LL groups than in the CO group. These results confirm that Lentinus edodes reduces blood pressure levels and serum total cholesterol concentration in spontaneously hypertensive rats. But the effects of Lentinus edodes did not differ significantly based on whether the Lentinus edodes was harvested early or late.

  • Serum and liver lipid levels and fatty acid composition of liver phospolipids (PL) were investigated in 36 rats which consumed either one of five different dietary fats or a high carbohydrate diet for 4 weeks. As the sources of five dietary fats, concentrated cicosapentaenoic acid(EPA), fish oil (FO), perilla oil(PO), corn oil(CO) and beef tallow (BT) were provided to the rats. As a control group, cron starch (CS) replaced dietary fat. The FO group showed lower serum total cholesterol (TC), high density lipiprotein cholesterol(HDL-C) and serum PL levels than those of the CO group(p<0.05). There were no significant differences in serum TC and serum HDL-C levels between the polyunsatured fatty acid(PUFA) groups and the EPA, FO and PO groups. The CS group showed the highest level serum TC. Compared with the CS group, both the EPA and CO groups showed significantly lower atherogenic indices(AI). However, there were no significant differences in AI among different dietary fat groups. No significant differences in liver triglyceride (TG) , TC and PL levels were detected among the six experimental groups. Phosphatidylcholine(PC) and phosphatidylethanolamine(PE) composed 30-40% and 15-20% of total liver PL, respectively. The fatty acid composition of liver PC and PE reflected dietary fatty acid composition . Compared to the different dietary fat based diets used in our study, the high carbohydrate diet had the most adverse effects on serum lipid profiles. However, we can not conclude from this result that long chain n-3 PUFA diets such as the EPA and FO based diets have more beneficial effects on serum lipid profiles than n-6 PUFA diet such as the CO based diet or shorter chain n-3 PUFA diets like the PO based diet.

  • This research was designed to study the effect of Korean dietary lipids on the lipid metabolism and the immune function in young rats . The three different lipid sources were compared lard, perilla oil and fish oil. Three different levels of lipid in the diet, 2%, 15% and 30%,on the weight basis, were included. After four weeks feeding, the rats were sacrified and blood sample was collected to analyze for the total lipid, TG and cholesterol contents in serum. The HDL fraction in serum was seperated by the electrophoresis of lipoproteins. The immune responses were measured by the blastogenesis of spleen lymphocyte stimulated by PHA and in serum were measured. The following results were obtained. Lower body weight gain was shown in 30% lipid diet fed group on the isocaloric basis. In concerning the different dietary lipid sources, there were significantly lower boyd weight gain in fish oil than in perilla seed oil and lard group in 30% lipid groups. Deposition of body fat expressed by epididymal fat pad in serum were significantly different among perilla seed oil, lard and fish oil groups. Perilla seed oil group showed lowest level of total lipid and TG in serum regardless of dietary fat level. The feeding perilla seed oil to rats was resulted in lower serum cholesterol levels than lard in all three levels of fats tested. The HDL fraction was elevated in perilla seed oil group at the high fat level. The stimulating responses of lymphycotes by PHA did not seem to be influenced by different dietary fat sources. However, conA mitogenic responses was significantly increased in perilla seed oil group. The lower level of perilla seed oil (2%, 15%) showed slightly higher responses of ConA, indicating that lower level of perilla seed oil might have stimulatory response on the immune response. The number of antibody forming cells of spleen against SRBC was increased in 30% fat level for all the three kind of fats. However, no effect has been found in plaque forming cell response by the differences in dietary fat sources. There were no significant differences in serum IgG and IgA levels in all dietary groups.

  • This study was carried out to investigate the supplementary effects of ${\gamma}$-oryzanol extracted from rice bran on lipid metabolism in diabetic mice. We supplied 2 kinds of experimental diets (CO without and GO with 0.2% ${\gamma}$-oryzanol) to diabetic mice for 8 weeks. Diet intake, body weight, organ weight, contents of serum and hepatic lipid profiles, and fecal lipid levels were measured. Though there was no significant difference in diet intake, body weight change and organ weight between experimental groups, the concentration of serum total cholesterol and hepatic total lipid, total cholesterol and HMG-CoA reductase activity was significantly lower in GO group treated with 0.2% ${\gamma}$-oryzanol of diet than CO group after supplementary period of experimental diets. And total lipid, triglyceride, total cholesterol, and bile acid levels excreted to feces were significantly higher in GO group than CO group. These results suggest that ${\gamma}$-oryzanol decrease the serum and hepatic lipid levels by lowing HMG-CoA reductase activity or increasing the contents of fecal lipid in diabetic KK mice.

  • The effects of dietary Ca and Na levels on lipid metabolism in hyper lipidemic/hypercholesterolemic rats were examined. In Expt. 1, normal rats were divided into six groups and fed high fat(15%, w/w)/cholesterol(1%, w/w) diet containing two levels of Na, low (0.05) or high(1.5%) and three levels of Ca, low(0.1%), normal (0.5%), or high(1.5%) for 8 weeks. In Expt. 2, hyperlipidemia / hypercholesterolemia rats were induced by feeding high fat / cholesterol diet for 4 weeks. They were divided into four groups and fed the high fat / cholesterol diet, containing two levels of Na, low or high and two levels of Ca, low or high for 4 weeks. In Expt. 1, total lipid and total cholesterol contents in serum and liver were significantly lower in rats fed high Ca diet than in rats fed normal or low Ca diet regardless of dietary Na levels. Serum TG was the highest in rats fed low Ca and low Na diet. In Expt. 2, Serum total lipid, TG, and total cholesterol levels decreased by 24, 35, 26% respectively in rats fed high Ca diet regardless of dietary Na levels. Serum total lipid level tended to increased in rats fed low Na diet. The total lipid and TG contents in liver slightly decreased in rats fed high Ca diet. Another observation was that high Ca intake significantly faciliated the fecal lipid and cholesterol excretion regardless of dietary Na levels. There results suggest that the hypolipidemidc/hypocholesterolemic effects of high Ca diet could be partly due to increase in lipid and cholesterol excretion and these effects may be independent of dietary Na levels.

  • The purpose of this study is to analyze the effects of exercise therapy on serum lipid levels and antioxidants of obese and normal college female students. The subject group composed of ten normal-weight students(below 30% body fat ratio) and ten obese students(above 30% body fat ratio). After a pilot test, the subjects were given an eight-weeks exercise program. Before and after the exercise program, the subjects were given test for serum lipid and antioxidants were analyzed. The SAS program was used in the data analysis. The statistical measurements employed here were T-test, Wilcoxon signed rank test, and Wilcoxon rank sum test. The results of this research are as follows. 1) The effects of exercise therapy on serum lipid levels : Before the exercise therapy, the levels of Total-cholesterol, Triglyceride and LDL-cholesterol of the obese group were highier than those of the normal-weight group. However, the HDL-cholesterol levels were highier in the normal-weight group than in the obese group, but these differences were not significant. With the exercise therapy, the levels of Total-cholesterol increased gradually. The HDL-cholesterol increased gradually, the LDL-cholesterol level decreased in both groups, However, the Triglyceride level decreased in the obese group and increased in normal group, but the difference was not significant. 2) The effects of the exercise therapy on serum antioxidants ; Before exercise therapy, the serum FR and GSSG levels of the obese group were significantly highier than those of the normal-weight group(p=0.00, p=0.04). The serum GSH level of the normal-weight group was highier than that of the obese group, and the serum MDA level of the obese group was highier than that of the normal-weight group. Again these differences were not significant. With exercise therapy, serum FR level was reduced and serum GSSG level significantly increased in both group(obese group p=0.01, normal-weight group p=0.01), The serum GSH level of the obese group significantly increased (p=0.01), and serum MDA level significantly increased in the obese group(p=0.01), but the difference in the normal-weight group was not significant. These results show that regular exercise therapy reduces serum FR levels and activation of antioxidant systems, and suppress oxidative stress. These effects were slightly highier in the obese group than in the normal-weight group. The regular exercise therapy decreased the serum Triglyceride levels more in the obese group than in the normal-weight group. However the improvement of the serum lipid profile may require a longer exercise period than eight weeks. The results show that the exercise therapy was overall more effective in the obese group than the normal-weight group.

  • This study was performed to investigate the influence of dietray food from the three CHinese medicinal herbs(Mugwort, Dried organge peel and Duchung) on lipi d metabolism in rats. Male rats of Sprague-Dawley strain were divided into four dietary groups(Cellulose (CL), Mugwort(MW), Dried organge peel9OP), Duchung(DC)) after three weeks of hyperlipidemic dieting and were fed ad libitum each of the experimental diets for six weeks. The fiber sources of the experimental diets were prepared by drying and milling mugwort, orange peel, duchung and cellulose. Each of the Fiber sources was mixed into the diet to achieve 10g% levels of total dietary fiber. Levels of apparent fat absorption exhibited a significant decrease in the MW and DC groups. The OP group also showed a decreasing trend, but to a lesser extent. The levels of serum total lipid were not significantly different among the four experimental groups. Total serum cholesterol levels were significantly lower in the OP grop that in both the CM and MW group. Serum TG and LDL-cholesterol levels were significantly higher in the DL group than other groups. Serum HDL-cholesterol levels were significantly levels were significantly lower in the CL group than in the other groups. Total lipid and total cholesterol in liver were significantly higher in the CL group than in the other groups. Total lipid and total cholesterol in feces displayed a significantly increase in the MW and DC groups when compared with the CL group. The OP group also showed an increase compared to the CL group.
