“…At a concentration of 10V3 M, benzoyleegonine produced approximately 40% inhibition of verat~dine-st~ulat~ 22Na+ uptake in an assay with rat brain membrane homogenate (Matthews and Collins, 1983). At daily doses of 60 mg/kg benzoylecgonine orally, mice exhibited normal immune responses (Watson et al, 1983). Mice dosed with 60 mg/kg benzoylecgonine had suppressed plaque forming cell/lo6 spleen cell responses (Watson et al, 1983).…”
