Morphometric Study Of The Teratogenic Effect Of Artesunate On The Central Nervous System Of The Wistar Rat Foetus

The teratogenic influence of maternal administration of artesunate on the morphometry of foetal nervous system was studied. Twenty virgin female Wistar rats weighing between 200g and 230g were used for this study. The animals were divided into 4 groups of 5 rats each. Each group was kept in a separate plastic cage. The rats were fed with commercial rat feed and tap water ad libitum throughout the experimental period. The females were caged overnight with sexually mature male rats of the same strain. The presence of sperm (tailed structures) in the vagina smears obtained the following morning confirmed coitus and the sperm positive day was designated as day zero of pregnancy. Oral doses of 0.2mg/kg, 0.4mg/kg and 0.8mg/kg body weight of artesunate were administered to pregnant rats in 3 of the groups respectively from the 7th to the 11th day of gestation. The fourth group of rats was used as the control which received 2.0ml/kg body weight of distilled water on the same days. Results show that the high dose group rats demonstrated significant (
