Some selected haematological indices in Wistar rats in the vanadium-ethanol interaction.

Abstract

1. Wistar rats of both sexes daily received an ethanol solution of ammonium metavanadate (AMV) of 0.3 mg V/cm3 5% ethanol concentration as sole drinking liquid, for a period of 4 weeks. 2. The reference groups received for drinking aqueous AMV solution, or 5% ethanol, or water. 3. In animals drinking both water and ethanol AMV solution a decrease in the erythrocyte count and haemoglobin level was noted together with an increase of the percentage of reticulocytes and polychromatophilic erythrocytes in the peripheral blood. 4. A small rise of the percentage of polychromatophilic and orthochromatic erythroblasts was at the same time noted in the bone marrow of animals receiving ethanol AMV solution. 5. In the group of animals drinking 5% ethanol a fall of the erythrocyte count was observed and a rise of the leukocyte count, particularly of lymphocytes. 6. Substitution of water by 5% ethanol solution as solvent for AMV did not have any distinct influence on the toxicity of the tested compound.
