Morphological and biochemical characteristics in the experimentally treated rats with indigenous synthetical products used as pesticides.

In acute experimental intoxication with 3 indigenous pesticides (Tripinacloraz, Lemax and Maleic Hydrazide-Na salt) the changes of some biochemical parameters, reflecting the degree of hepatic structural alterations, were studied. The pesticides were administered by gastric gavage in a single dose close to DL50 to Wistar male rats. The morphological alterations were in good correlation with a different hepatocellular levels localization. Reversible morphological lesions (granulovascuolar like dystrophy and circulatory disorders) without any pathological significance on dose-effect correlation induced a progressive response especially on serum ceruloplasmine, leucinaminopeptidase and lactatdehydrogenase.
