RESUMO
Objective To explore the effects of Sishen Pills on Ghrelin-CaM-MLCK signaling pathway with sinuses ventriculi in diarrhea rats of yang deficieney of spleen and kidney; To discuss its mechanism of action. Methods A model rats with diarrhea model of yang deficieney of spleen and kidney was established by treated with intragastric administration of adenine and Senna water decoction to replicate. 72 SD rats were randomly divided into normal group, model group, positive medicine group, Sishen Pills high-, medium- and low-dose groups, with 12 rats in each group. Each medication group was given relevant medicine for gavage, for 14 days. Immunohistochemistry and Western blot were used to detect the expressions of Ghrelin and GHSR, CaM, and MLCK protein in the sinuses ventriculi. Results In the model group, Ghrelin, GHSR, CaM and MLCK protein expressions of the sinuses ventriculi significantly increased (P<0.01). In each medication group, protein expression of the indexes was lower than the model group (P<0.05, P<0.01). The Sishen Pills high-dose group was particularly obvious. Conclusion The effect of Sishen Pills on diarrhea model rats of yang deficieney of spleen and kidney may be associated with regulation of index protein expression in Ghrelin-CaM-MLCK signaling pathway.
