The effect of the aqueous extract of the leaves of Bambusa vulgaris on blood pressure was evaluated in normotensive male rabbits. Blood pressure was measured by the invasive method. Thus, aqueous extract of Bambusa vulgaris leaves had been injected intravenously at doses ranging from 1 mg/kg to 30 mg/kg in rabbits anesthetized with thiopental. The effects of this extract on blood pressure were also evaluated in rabbits having previously received different doses of atropine. The aqueous extract of Bambusa vulgaris leaves induced a dose-dependent hypotension which is not canceled in the presence of atropine. The results obtained show that the extract has blood pressure lowering effect which may be mediated by muscarinic-type cholinergic receptors.展开更多

The safety evaluation of the vaccine has been reported, but the teratogenic potential was not studied. In the experiment reported herein we have studied the teratogenic action of the vaccine in the progeny of rabbits. No congenital anomalies were observed.展开更多
