Abstract:
An experiment was conducted for a period 4 months in 120 female wistar rats to study the oestrus cycle pattern in hexavalent chromium toxicity. Experimental rats were divided into six groups with four replications containing five rats in each. These were fed with control and experimental feeds and rats and were subjected to examination of oestrus cycle pattern by vaginal smear examination for cellular composition. Studies revealed that there is an extreme variation in its regular cycles which was varied from its physiological limits in toxic groups while distinct amelioration has been observed in ameliorative groups.
