title: Safety assessment of the royal sun mushroom, Agaricus brasiliensis (higher Basidiomycetes) intake during rat pregnancy.
abstract: In this study, we investigated the reproductive capacity of pregnant rats exposed to daily orally administered powder-dehydrated reconstituted of Agaricus brasiliensis (=Agaricus blazei sensu Murrill), the fetal organogenesis, and the development of the pups. Pregnant rats were exposed for the entire gestational period to water (control) and A. brasiliensis at 300 or 600 mg/kg/day. Fertility and body weight of dams were monitored. Pups were monitored for body weight, offspring vitality, morphology, and physical and neurobehavioral development. An increase in sternebrae agenesis was observed at the 600 mg/kg/day dose of A. brasiliensis, while incomplete ossification of sternebrae was seen even at a 300 mg/kg/day dose. In conclusion, this study is the first to demonstrate the impact of maternal exposure to A. brasiliensis on the fetal organogenesis and development of offspring in a rat model. The 600 mg/kg/day dose showed some negative effects, and low toxicity was observed at the 300 mg/kg/day dose.
