Effects of graded dosages of methanolic extract of Aspilia Africana were examined on the estrous cycle, uterine weights and histology to determine its effects on the reproductive functions of 25 cyclic female rats. The rats were randomized into five groups A, B, C, D, and E. They were given Omg/kg body weight, 150 mg/kg body weight, 200 mg/kg body weight, 250 mg/kg body weight, and 300 mg/kg body weight, respectively. The effect on the estrous cycle was determined by vaginal lavage while routine histological preparations were done with haematoxylin-eosin stains. All values were statistically compared at appropriate confidence intervals. Estrous cycles were significantly reduced in a dose-dependent manner and histology revealed a dose-dependent toxicity.
Se examinaron los efectos de las distintas dosificaciones de extracto de metanol de Aspilia africana, en los ciclos estrales, peso uterino y en la histología para determinar sus efectos en las funciones reproductivas de 25 ratas hembra.
