Relationship between serum lipids, lipoproteins and pseudocholinesterase during organophosphate poisoning in rabbits.
The activities of serum pseudocholinesterase, lecithin: cholesterol acyltransferase (LCAT) and gamma-glutamyltransferase in rabbits were investigated before and after dichlorvos administration in vivo. The effects of this organophosphate on some serum lipids and lipoprotein fractions were also determined. LCAT activity remained almost unaffected after organophosphate administration. However, serum gamma-glutamyltransferase and pseudocholinesterase activities markedly decreased. Dichlorvos markedly lowered both serum low density lipoprotein (LDL) and cholesterol contents, whereas high density lipoprotein (HDL) concentration increased and very low density lipoprotein (VLDL) remained unaffected. Triglycerides as well as esterified fatty acids increased significantly but the statistical changes in free fatty acid concentrations were not significant, because individual variations in fatty acid concentrations were high.
