    Abstract:
    Rat serum lipoprotein phospholipids and serum cholinesterase activity in control and thioacetamide-treated rats (50 mg/kg/day for 30 days) were studied. Analyses were done after 1, 3, 8 and 30 intraperitoneal doses of thioacetamide or 0.15 mol/l NaCl. Cholinesterase activity significantly increased with thioacetamide treatment. Only two phospholipids: LDL-phosphatidylcholine and HDL-lysophosphatidylcholine appeared associated with cholinesterase activity. LDL-phosphatidylcholine increased through the action of hepatotoxic thioacetamide while HDL-lysophosphatidylcholine significantly decreased. Because of the high statistically significant association between changes in these lipoprotein phospholipids and in cholinesterase in this model of hepatic injury, we conclude that cholinesterase could be involved in the regulation of these phospholipid levels.
