Abstract
The study was initiated to detect the change in serum cholesterol, triglycerides, lipoprotein pattern and tissue lipids (liver, intestine cholesterol and . total lipid) in response tQ feeding d.ifferent type.s of saturated fats hy’drogenated cotton-seed-oil namely (Fanar), margarine, mutton and corn-oil as unsaturated fat at two levels of intake 5 and 25~ The importance of this study is based on the fact that atherogenic index included cholesterol, triglyceride, low-density-lipoprotein (L.D.~) and high-densitylipoprotein (H.D.L) were significantly affected by the type and amount of fat available in diet as well as environmental factor. The results indicate that feeding corn-oil at 5 produced the lowest value of serum cholesterol in both male and female rats. High-density-lipoprotein was :inversely related to serum cholesterol level, but 100density-lipoprotein (L.D.L) showed a positive association with serum cholesterol.. Mutton increased low-density lipoprotein ratio followed by margarine to a minor degree. Total cholesterol in l1ver increased when rr ts were fed diets containing high level of saturated fat 25. but intesthle cholesterol inareased when rats were fed 5of saturated fats. Unsaturated fat corn oil produced the lowest lev:el of circulating and tissue oholesterol at two levels of dietary fat feeding 5 and 25. Serum triglyceride was affected significantly by the level and type of dietary fat, when the level of dietary fat was 25serum triglyceride was elevated and very-low-density-lipoprotein increased. Mutton and margarine produced the highest level of serum triglyceride and very-low-density-lipoprotein, lowest levels were produced by feeding corn-oil at two levels 59~ and 25 in both male and female rats. Total liver lipids Y1ere affected by the level and ty’pe of fat in the diet, higher levels were observed in rats fed 25 saturated fat and animals accumulated and deposite fat in protenial Qa~ty and other tissue. Intestine total lipids increased by feeding rats 25 level of sattlrated fats and decreased when the level at fat was minimized to 5. Sex appeared to have a significant effect 01. these values and male rats showed higher values when compared with female rats. Feeding mutton at 5produced the highest level of serum cholesterol in both male and female rats and corn-oil produced the lowest value in both male and female (table 5A). The second experiment was conducted to estimate the effect adding garlic (alliruh-stavium) and pomegranate (punica-granetum)at two levels of addition 5
