ABSTRACT
The effect of thermally-oxidized soyabean oil-based diets on the lipid profile of the testes of rats was studied. For 35 days; two groups of male weanling rats were fed a basal diet containing unoxidised and oxidized soyabean oil. Rats fed the thermally oxidized soyabean oil diets displayed typical signs of essential fatty acids (EFA) deficiency and had their testes weights reduced to about 81 of fats fed unoxidised soyabean oil diets. There was a significant decrease (p0.05) in phosphatidylcholine and diphosphatidylglycerol content and increase in cholesterol (p0.005) content of the testes of rats fed oxidized soyabean oil-based diet compared to those fed unoxidised oil diets

Possible alterations in total plasma cholesterol; triglyceride; HDL-cholesterol and LDL-cholesterol concentrations were studied in forty healthy human subjects (twenty-two males and eighteen adult females) after twenty eight days of tea consumption. A commercial brand of tea preparation was drunk by each of the subjects and they were made to take two standard cups (4.0g) of tea infusion per day. The result showed a significant decrease in mean HDL-cholesterol and increase in LDL-cholesterol concentrations compared with the mean control values. The mean total cholesterol was statistically unchanged. When the subjects were grouped into males and females; the mean LDL-C concentration was significantly elevated in both male and female groups while the mean HDL-C and triglyceride levels only in female subjects when compared with the corresponding control group. The difference observed in the value of the mean total cholesterol was not statistically significant in individual male and female groups.Findings from this study suggest that tea consumption could affect the metabolism of atherogenic lipid fractions and may thus be important in the aetiology of coronary heart disease
