Abstract
Backgrounds & Objectives : Yukgunjatanggranule (YGJT) ha been used for the treatment of functional dyspepsia, regarded as one of the gastric dysmotility diseases, but its mechanisms of cation are not yet well known, We investigated the effects of YGJT 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 1 hour and 2 hours after administration ofnormal saline (NS) or YGJT 41.6mg/kg or 124.8mg/kg in rats. By the same method, gastric emptying was measured only for 2 hours after administration of NS of YGJT 124.8mg/kg in rats treated with atropine sulfate (1mg/kg, s.c), quinpirole HCl(0.3mg/kg, i.p.), NAME (NG-nitro-L-arginine methyl ester, 75mg/kg, s.c.) or cisplatin (10mg/kg, i.p.) to delay gastric emptying. Results : YGJT 124.8mg/kg improved gastric emptying more than NS or YGJT 41.6mg/kg (p=0.046). Under delayed gastric emptying, YGJT 124.8mg/kg improved gastric emptying in the group treated with cisplatin (
