Methods: 16 male SD rats were randomly divided in the control group and spleen qi deficiency group (model group)—8 rats each group;spleen qi deficiency model of the improper diet and overfatigue was established;the SI propelling rate (SIPR) was used to evaluate the SI motility;ELISA was used to measure concentrations of acetylcholine (ACh), cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA) in the SI tissue;immohistochemistry was employed to detect expressions of cholinergic M2 and M3 receptors. Results: Compared with those in the control group, SIPR was reduced;expression of M2 receptors was increased;and expression of M3 receptors and concentrations of cAMP and PKA were decreased, significantly, in the model group. Conclusions: Expression imbalance of cholinergic M2 and M3 receptors might contribute to the motility reduction of the SI in spleen qi deficiency.展开更多

[ Method] Eighteen piglets with reserpine-induced spleen deficiency and diarrhea were selected and randomly divided into three groups, six per group, including Guchang Cuzhang powder group, Smeeta group and spleen deficiency control group. Piglets in two drug adnfinistration groups were treated for 7 d using Guchang Cuzhang powder and Smecta, respectively. On the 2nd d and 8th d after drug withdrawal, three piglets in each group were euthanized by jugular vein bleeding to death. Intestine segments in different groups were collected for paraffin embedding, section preparation and HE staining, to conduct histological observation and count the number of small intestinal epithelial lymphocytes. [ Result ] Compared with the spleen deficiency control group, the number of lymphocytes in small intestinal epithelium of piglets in two drug administration groups increased significantly; in addition, the number of lymphocytes in small intestinal epithelium of piglets in Guchang Cuzhang powder group was significantly higher than that in Smecta group. [ Conclusion ] This study provided theoretical basis for the clinical applieation of Guchang Cuzhang powder and Smecta.展开更多
