Abstract :
Garlic is a medicinal herbwith antioxidant, anti-hyperlipidemic and antidiabetic properties which is extensively used in the treatment of diseases. The purpose of the present study was to assess probable hematologic alterations and the activity of some erythrocyte antioxidant enzymes following garlic administration in dogs. In this study, ten male dogs were treated with garlic tablet with a dosage of 100 mg/kg, once daily for 45 days. Blood samples were collected three times on days zero, 45 and 60 of the experiment. Complete blood count (CBC), erythrocyte morphology, reticulocyte count, Heinz body and erythrocyte osmotic fragility test were performed. The activity of erythrocyte antioxidant enzymes including SOD (superoxide dismutase) and GPX (glutathione peroxidase) were also assessed. Garlic administration in dogs caused a significant reduction in erythrocyte count, hematocrit and hemoglobin concentration on day 60 compared to day zero (p < /em><0.05). In addition, a significant decrease was observed in mean corpuscular hemoglobin (MCH) on days 45 and 60 and mean corpuscular hemoglobin concentration (MCHC) on day 60 (p < /em><0.05). Osmotic fragility assessment of RBC’s indicated that the percentage of hemolysis was significantly decreased in 0.55%, 0.50%, 0.45% and 0.40% salt concentrations (p < /em><0.05). Moreover, a significant increase was observed in the activity of erythrocyte antioxidant enzymes, SOD and GPX on day 60 (p < /em><0.05). The present study showed that garlic tablet administration with the dosages used in the present study, did not induce considerable destructive effects on erythrocytes while improving antioxidant defense system and osmotic tolerance of red blood cells.
