ABSTRACT
Objective: To research the effect of Xinkai Kujiang method on gastric myoelectrical activity and autonomic nerve function in functional dyspepsia(functional Thirty,FD) rat,and to reveal the overall regulatory mechanism of Xinkai Kujiang method and help for the clinical trials and treatment.Methods: FD rats being the experiment subject,we observed the effects of Xinkai Kujiang method on FD rat gastrointestinal movement,including the following index,the main frequency,power,even the percentage of slow wave duality.Meanwhile we observed the effect of Xinkai Kujiang method on FD rat heart ratevariability(HRV),evaluated the effect on autonomic nerve function,and revealed FD rats overall adjustment mechanism.Results: Before treatment,the result of model group,weikangning group and the normal control group was significantly different(P0.05),but that of weikangning and the model group had significant differences(P0.05),weikangning group change trend was significantly different(P
ABSTRACT
Objective To study the effect and mechanism of Xinkai Kujiang method(TCM treatment with the pungent and bitter herbs to regulate the gastrofunctions)on the functional dyspepsia(FD)rats.Methods Twenty-four rats were randomized into control group,model group,and Weikangning(herbal medicine for dyspepsia)group,with 8 in each.After a 7-day adaptive feed,the FD models were made with the clipping tail stimulation.Seven days after modeling,the Weikangning group was given Weikangning Capsule 0.625g/kg by gavage,twice a day,and the other two groups were given normal saline in the same dosage.The medication was appliey in succession for 12 days,and on the thirteenth day,the serum and gastric tissues were collected for detecting the lab indications:plasma motilin(MTL),plasma nitric oxide(NO),gastric tissue MTL,nitric oxide synthase(NOS),and the expression of Cajal interstitial cells(ICC)and gastrointesinal smooth muscle cells(SMC).Results Compared with the control group,the level of plasma MTL in the model group was significantly decreased,the level of NO significantly increased,and the expression of MTL,ICC and SMC positive neurons in the stomach myenteric nerve plexus was significantly weakened,but the expression of NOS positive neurons was significantly strengthened(P
