Effect of byakko-ka-ninjin-to on the efferent activity of the autonomic nerve fibers innervating the sublingual gland of the rat.
The effect of intraduodenal infusion of Byakko-ka-ninjin-to (BN) on the efferent activity of the autonomic outflow to the sublingual gland was observed in the anesthetized rat. Intraduodenal infusion of BN (50-200 mg/kg) resulted in a dose-related increase in efferent activity. The enhancement of the nerve activity following administration of 200 mg/kg BN lasted longer than three hours. It was observed that the suppressive effect on efferent activity due to i.v. administration of hypertonic saline was antagonized by intraduodenal infusion of BN. From these observations it is suggested that Byakko-ka-ninjin-to acts as a facilitatory agent on salivary secretion.
