Histological effect of aqueous extract of Anacardium occidentale (Cashew) stem bark on adult Wistar rat testis
In medical practice, Anacardium occidentale stem bark is used for various ailment treatments. Possible histological effects of aqueous extract of A. occidentale stem bark administration was studied on adult Wistar rat testes. The rats (n=24), weighing 164 to 210 g were randomly assigned into three treatments (n=18) and control (n=6) groups. The rats in the treated groups II, III, IV received 20, 40...

A model of bidirectional regulation induced by a combination of one stimulatory and one inhibitory agent on gastric smooth muscle contraction
In this paper, we proposed a model of counterbalance resulting from bidirectional regulation on gastric smooth muscle contraction in the absence of nervous and endocrine system control. To verify the propose, we suggested that a combination of one stimulatory and one inhibitory drug should produce bidirectional regulation on the contractility of gastric smooth muscle and myosin activity, depending on the contractile...
