Abstract
An environmental pollution with commonly used insecticides effected the homer pigeon this study used dichlirvous, diazinon and cypermethrin in several subacute doses The enzyme activity was measured by modified electometric method as ΔpH/ 30 min. The Confidence interval in the plasma were 0.197 respectively and those of the erythrocytes were 0.934 respectively. The organophosphorus insecticides diazinon at dose (5-10) mg kg b.w. significantly inhibited plasma (28~53%) and erythrocyte 53% and dichlorvous at dose (5-10) mgkg b.w. significantly inhibited plasma (33~38%) and erythrocyte 52% cholinesterase in vitro in a concentration-dependent tanner. The insecticides cypermethrin at dose (20-40) mg kg b.w. significantly inhibited plasma lactic dehydrogenase in (4~9.5%).
