Abstract:
:Male rats were administered diets containing monobutyl (MBP), mono-iso-butyl (MIBP), monooctyl (MOP) or mono-2-ethylhexyl phthalate (MEHP) for 1 week, and serum lipid compositions were determined. Non-esterified fatty acid was increased and triglycerides and total cholesterol were decreased in all monoester-treated groups. Fatty acid composition of triglycerides, cholesteryl esters and phospholipids showed similar alteration in the treated groups.
