Blood determinetions were carried out on a number of 15 blood samples collected on anticoagulant, following the next parameters: number of erythrocytes, hemoglobin, Hct, WBC count, etc., with a Coulter Counter analyzer.
For biochemical determinations were harvested 15 serum samples aiming to those parameters that can be modified in case of chronic toxicosis: serum total protein (Pt); gamma globulins; urea by urease colorimetric method; alkaline reserve by the volumetric method; glutamic oxalic-acetic transaminase (SGOT) and glutamic pyruvic transaminase (SGPT) by colorimetric method with dinitrophenylhydrazine.
