Backgrounds & Objectives: Banhasasimtang granule(BHSST) has been used for the treatment of functional dyspepsia regarded as one of the gastric dysmotility disease. but its mechanisms of action are not well known yet: So we investigated the effects of BHSST on gastric emptying and its mechanisms of action in rats.
Methods: Gastric emptying was measured by glass beads(1mm in diameter) expelled from the stomach for 60 min after administration of normal saline(NS) or BHSST 31mg/kg or 93mg/kg in rats. And by the same method gastric emptying was measured after administration of NS or BHSST 93mg/kg in rats treated with atropine sulfate(1mg/kg, s.c.), quinpirol HCI(0.3mg/kg, i.p.), NAME(NG-nitro-L-arginine methyl ester, 75mg/kg, s.c.) or cisplatin(10mg/kg, i.p.) to make delayed gastric emptying.
Results: BHSST 93mg/kg improved gastric emptying more than NS or BHSST 31mg/kg(p=0.016). Under the delayed gastric emptying, BHSST 93mg/kg improved gastric emptying in the group treated with NAME(5.00{pm}3.101;vs;9.00{pm}3.51,;p;=0.046), but aggravated it With atropine sulfate(5.71{pm}3.45;vs;2.57{pm}1.62,;p;=0.050) and cisplatin(12.7{pm}2.29;vs;8.57{pm}5.06,;p;=0.072).
Conclusions: BHSST improves the gastric emptying through cholinergic and 5-hydroxytryptamine 3 receptors. Especially it is effective to improve gastric emptying delayed by NAME. So we expect that it would be effective in functional dyspepsia with impaired reservoir functions such as gastric adaptive relaxation.
