Abstract:

Cypermethrin (Cyp), a synthetic pyrethroid developed for agricultural and public health applications has become harmful to the environment and mammalian life owing to indiscriminate uses. This study investigated the ameliorative effects of the methanolic leaf extract of Jatropha gossypifolia (JG) on cypermethrin-induced alterations on the haematological status and estrous cycle of female wistar rats. Eighty female wistar rats were divided into ten groups of eight animals each and subjected to various treatments: sixty days of cytology and thirty days of oral administration. Group 1 was given corn oil only. Group 2was administered with cypermethrin (20 mg/kg) only. Group 3, 4, 5 and 6 were co-administered with cyp+JG50 mg/kg, cyp+JG100 mg/kg, cyp+ALA50 mg/kg and cyp+VC50 mg/kg respectively. Group 7, 8, 9 and 10 were given only JG50 mg/kg, JG100 mg/kg, ALA50 mg/kg and VC50 mg/kg respectively. Vaginal smears were collected from each rats and viewed under a light microscope before and during the period of administration. The animals were sacrificed after the 28th day. The whole blood was collected and used for haematological analyses. Results obtained from this study showed that cypermethrin administration significantly (p
