ROLE OF DIETARY LIPIDS AND BUTYLATED HYDROXY ANISOL (BHA) ADMINISTRATION ON ALBINO-RATS .1. SERUM UNSATURATED FATTY-ACIDS

Adult male albino rats were supplemented with edible plant oils, corn maize and cotton seed oils and their semihydrogenated forms (Heliopoli s and Sultan cooking fats) for a period of 3 months. In general, the s upplementation of tested oils produced increasing effect on the serum levels of total C18:1, C18:2 and C20:4 unsaturated fatty acids (UFA). The increases were significant in case of feeding corn maize oil and S ultan cooking fat for total and C18:1 and C18:2 UFA. However, the degr ee of significance was intensified by the feeding of cotton seed oil a nd Heliopolis cooking fat. Supplementation of Sultan cooking fat showe d a significant increase in serum level of C20:4, while the other test ed oils and Heliopolis cooking fat produced very highly significant in crease. Butylated hydroxy anisol (BHA) produced no effect on the level of UFA when administered with dietary tested edible lipid but its rol e revealed by maintaining the higher level of UFA due to administratio n of oils and its semihydrogenated analogous.
