The environmental pollution by heavy metals has become a significant hygenic problem. Recently it is said the garlic supplementation in diet have protective effect on the heavy metal accumulation in tissue of rat by a researcher. In this study two experiments were undertaken.
Firstly, dogs were fed diet supplemented with cadmium of cadmium plus 7% of raw garlic for 50 days. on the 50th day of experiment all dogs were euthanasied and the cadmium content of various tissue were measured by atomic absorption spectrophotometeric method.
Secondly, in order to find out the toxic effect of garlic dogs were fed diet supplemented with 7% of raw garlic for 50 days and hematological or hematochemical observations. were undertaken at 10 day intervals.
The results obtained from these experiments were summarized as follows;
1. In dogs treated with cadmium and cadmium plus garlic cadmium was accumulated in renal cortex, liver, and muscle. However the concentrations of cadmium showed no significant between the two group.
2. In dogs fed diets supplemented with 7% of raw garlic significant decrease of erythrocyte count, packed cell volume and hemoglobin content and significant increase of Heinz body erythrocyte and reticulocyte count were recognized.
3. The garlic-treated dogs and control dogs had normal asparate aminotransferase, alanine aminotransferase, alkaline phosphotase, blood urea nitrogen value. The value showed no significant difference between the two group.
4. From these results it may be concluded that the garlic have protective effect for cadmium accmulation in tissue and excess garlic in diet could induce hemolytic anemia in dogs.
