The frequency of the infective larvae of Toxocara canis, the common parasite of the dog was assessed in brain portions of male Albino mice ingested two doses: 200 mg/Kg and 400 mg/Kg of potassium dichromate-hexavalent (VI) as an indicator. Only 2,000 ova of the parasite were inoculated orally to twenty seven healthy young male mice. Frequency of the parasite was tested 13 weeks post-inoculation. Using bio-statistical analysis (one way analysis of variance) the frequency of detected larvae of both doses in the brain portions of the experimental animals showed an insignificant difference (P〉 0.05) in comparison with control. The results indicate the safety of small and mild intoxication doses of the potassium dichromate on distribution of Toxocara canis in brain portions of mice. 展开更多
