ABSTRACT
ive] To observe the effects of Shengjiang Capsule (SC) on gastric evacuation and to study its mechanism. [Methods] Eight-week-old SD rats were randomly allocated to five groups. Group A served as normal control, and Group B were treated with high dosage of SC, Group C with low dosage of SC, Group D with Zhike Baizhu Decotion and Group E with cisapride. After ten days of treatment, gas tric evacuation of rats was detected by isotope tracing method, erythrocyte-acetycholinesterase activity by micro-hydroxylamine method and plasma motilin (Mot) and somatostatin (SS) levels by radioimmunoas-say. [Results] Thirty-minute gastric evacuation rate was (51.44?.38)%, (40.82 + 7.24)% and (40.22?.16)% in Group B, Group C and Group D respectively, which was higher than that in Group A [ (33.18?.32)%]. Erythrocyte-acetycholinesterase activity, Mot and SS levels were (0.856?.128) umol/h, (124.26?5.94) ng/L and (39.42?.96) ng/L, and (0.726?.164 ) umol/h, (119.86 ?9.38) ng/L and (38.33 ?.64) ng/L in Group B and Group C respectively, which were higher than those in Group A [ (0.576 ?.150)/umol/h, (91.28 + 26.84) ng/L and (28.22 ?7.68)ng/L]. [Conclusion] SC can promote gastric evacuation, and its mechanism may be re lated to the increase of the cholinergic nerve function and plasma Mot and SS levels.
ABSTRACT
0.05),but the clinical cure rate in group A was higher than that in group B(P0.05),but the clinical cure and markedly effective rate in group A was higher than that in group B(P0.05),but decreased in group A(P0.05).Conclusion Liver-soothing and spleen-strengthening therapy can improve the gastric emptying and regulate plasma VIP content in patients with dysmotility-like functional dyspepsia(D-FD).
ABSTRACT
The effects of Xiangsha Liujunzi Decoction (XLD) on expermental bile-regurgitational gastritis and gastric evacuation in rats were observed. XLD in dose of 30g/kg (p.o.) markedly pre- vented the acute gastric ucosa damate induced by gastric feeding of alkaline intestinal contents. For chronic regurgitational gastritis rat model induced by pyloric dilation with regurgitation of duodenal juice after 2 and 4 weeks , XLD in dose of 30g/kg (p. o.) lowered the incidence of gastritis, and reduce intragastric pH and bile acid. XLD in dose of 15g/kg and 30g/kg (p.o.) markedly inhibited the gastric evacuation. The results suggested that XLD is available for the treament of bile-regurgi- tational gastritis.
