This experiment was undertaken to investigate and compare the effect of salt on the lipid composition in serm and liver of rats. The average body weight gains and food efficiency ratio were not affected by supplementation with salt in diet. Total cholesterol and free cholesterol levels in serum of all experimental diet group were slightly increased by supplementation with salt, while triglyceride levels were significantly increased. HDL-cholesterol levels of all salt supplementation groups were slightly lower than that of the control group, while LDL, VLDL-cholesterol levels of these groups were higher than that of the control group. The ratio of LDL, VLDL-cholesterol to HDL-cholesterol; so called, atheorgenic index, in serum of salt diet groups was slightly higher than that of the control groups. The ratio of LDL, VLDL-lipoprotein to HDL-lipoprotein in salt diet group were significantly higher than that of the control group. The weight of the liver was not affected by diet, but total cholesterol and triglyceride levels of the liver in salt diet groups were higher than that of the control group.

Mucor plumbeus FRI 0007 was grown on media containing starch solely as carbon source, urea as nitrogen source and minerals including magnesium, calcium and iron of different concentration. The ratio of nonpolar and polar lipid of the total lipid produced by the Muror plumbeus FRI 0007 changed by minerals added in the medium and incubation period. The nonpolar lipid content was higher on the medium containing only one mineral rather than 5 minerals and the nonpolar lipid consisted mainly of trig1yceride, free fatty acid and free sterol. The triglyceride content was higher on the medium containing one mineral and decreased with the incubation time lapse. The major fatty acid composition of total, nonpolar and polar lipid were oleic, palmitic and linoleic acid which comprised about 90% of total fatty acids and their compositions changed slightly depending on the minerals added in the medium.

Small dense LDL(LDL III) is emerging as a major risk factor for coronary artery disease. LDL III generation is associated with high triglyceride concentration, high hepatic lipase activity, and high cholesterol ester transfer protein (CETP) levels. CETP polymorphisms have been reported to be associated with coronary artery disease. In this study, we investigated the relationship between CETP polymorphism and LDL III generation. VLDL1, VLDL2, IDL and LDL subfractions were measured in 87 normal healthy Korean subjects who had been SNP genotyped for Taq1B, I405v and A629C. We found no differences in LDL subfractions and lipoprotein composition between homozygotes for Taq1B2B2, and those for Taq1B1B1 and Taq1B1B2. There were no differences in LDL subfractions and lipoprotein composition between homozygotes for 629AA, and those for 629AC and -629CC. However, homozygotes for 405VV had a significantly lower LDL III concentration and proportion than those for 405II and 405IV. We concluded that, among the Taq1B, I405V and A629C polymorphisms, only the 1405V polymorphism was associated with the concentration and proportion of LDL III.

This studies were conducted to find out the possibility of utilizing red pepper seed as resources of food fats, the research method was designed to make a comparison between crude and refined oil, and the results of the studies are as follows : The red pepper seed contained 28% of crude fat and 21% of crude protein. The main fatty acids of red pepper seed oil were linoleic acid(72.10~72.31%), palmitic acid(12.81~13.28%) and oleic acid(9.47~10.48%). The linolenic acid content was so small that is will not influence the autoxidation of the red pepper seed oil. The major triglyceride type of crude and refined oil of red pepper seeds were C52 and C54. The other types were found in a small quantity. The sterol composition of crude oil was $\beta$-sitosterol, campasterol, stigmasteral and brassicasterol,in the quantity order. after refining, brassicasterol was not detected, and the content was decreased by one six and one eight. The toropherol composition of crude and refined oil, tocopherol analog was composed of three kinds $\alpha$-, ${\gamma}$-, $\delta$-, but no $\beta$-form. the quantity of ${\gamma}$-, $\alpha$- and $\delta$-tocopherol were 162.91, 83.72, 43.98mg% respectively. The Quantity of and capsaicin in crude oil was 1,296 ppm, and it was reduced consicerably by refining and removed completely after the process of redeodorization.

The purpose of this experiment was to study the effects of feeding egg yolk prepared from quail fed winged bean oil on plasma and liver cholesterol and fatty acids composition in rats. Eggs were collected from laying quails that had been fed diets containing 5% of either animal tallow, soybean oil, corn oil or winged bean oil. Yolk powders (referred to as winged bean yolk, soybean yolk, etc.) were prepared and fed at the 15% level to weanling female Wistar rats for 28 days. Rats fed winged bean yolk had significantly lower body weight gain than did rats fed soybean yolk or animal tallow yolk. There are no significant effects on plasma total cholesterol, liver cholesterol and triglyceride concentration due to feeding yolk powder containing different oil. However, LDL-cholesterol increased and HDL-cholesterol decreased in rats fed winged bean yolk. Liver lipid of rats fed with winged bean yolk had a higher linoleic but a lower linolenic content than did those fed animal tallow yolk. However, rats fed with winged bean yolk had a lower linoleic content than did rats fed soybean yolk or corn yolk. In conclusion, winged bean yolk seemed to have had an adverse effect on rats.

This study investigated the hypolipidemic and antithrombotic effects of linolenic acid derived from Korean perilla oil. The experimental rats(male, Sprague-Dawley) were divided into 5 groups using a Randomized Complete Block Design and fed one of the five following diets : DO*/O#. D4/O, D4/4, D4/8, or D4/20(D*/# represents the ratio of linoleic to linoenic acid as the percentage of total dietary energy intake) for 4 or 8 months. Bleeding time and whole blood clotting time were determined and the composition of serum and platelet lipids analyzed. Comparisons from the DO/O to the D4/20 group showed that serum lipids (total lipid, triglyceride, total cholesterol, and HDL-cholesterol) gradually decreased with increasing linolenic acid intake - the hypolipidemic effect. The composition of platelet fatty acids[the ratio of eicosapentaenoic acid(EPA)/arachidonci aci(AA)] increased gradually with increasing linolenic acid intake. Higher linolenic acid intake increased bleeding time and whole blood clotting time, and decreased malondialdehyde(MDA) production in the platelets, though no significant differences. These results suggest that linolenic acid derived from perilla oil appears to suppress the conversion of linoleic acid to AA and the EPA transformed from linolenic acid appears to suppress the conversion of AA to TXA2. Since TXA2 is a platelet-aggregating and vasoconstricting agent, the redulction of TXA2 released by platelets with increasing intake of perilla oil containing a lot of linolenic acid confers an antithrombotic effect.

Effect of perilla oil on the fatty acid composition, ACAT and HMG-CoA reductase in the liver microsomes, or cholesterol and protein in serum of rabbit were examined. 1. The content of total protein in serum was almost same amount of both groups, but ${\alpha_1}-globulin$ and r-globuline were incresed or ${\beta}-globulin$ was decresed compared with control. 2. The content of high density lipoprotein incresed, and the content of low density lipoprotein decresed in lipoprotein. 3. Total cholesterol and triglyceride were decresed, and the content of phospholipid was incresed. 4. Perilla oil did not effect for changing blood glucose and $Na^+,\;K^+$ electrolytes. 5. Perilla oil did not effect for changing serum GOT and GPT in rabbit. 6. The activity of ACAT decresed and the activity of HMG-CoA reductase incresed. The activity of ACAT and HMG-CoA reductase in liver microsomes were reciprocal. 7. There were arachidonic acid 20:4, eicosapentaenoic acid 20:5, and docosahexaenoic acid 22:6 in the liver microsomes of rabbits. These highly polyunsaturated fatty acids were convented from linolenic acid 18:3 n-3.
