Abstract

Hematologic examinations, osmotic fragility tests, and scanning electron microscopy of erythrocytes were done on blood of dogs given 5 mg/kg of beta-acetylphenylhydrazine for 5 weeks. Reticulocytes, Heinz bodies, and serum total bilirubin values increased in the 1st week. Reticulocyte numbers peaked in the 2nd week, and reticulocytosis persisted through the 5th week. Erythrocyte, packed cell volume, and hemoglobin values decreased markedly and became lowest in the 2nd week. Mean corpuscular volume increased in the 1st week and remained increased for the duration of treatment. Erythrocyte osmotic fragility was increased after 1 week of treatment. Echinocytes were increased with a peak level of 47.6% at week 1 of treatment. Increased numbers of acanthocytes and schizocytes also were detected.
