Research on rationality of salt-processed composition of Buguzhi Pills through efficacy evaluation / 中草药

ABSTRACT

Objective: To investigate the effects of Buguzhi Pills and three kinds of simulative Buguzhi Pills on diarrhea rats with spleen-kidney yang deficiency, and to confirm the rationality of the salt-processed composition of Buguzhi Pills. Methods: SD rats were randomly divided into nine groups normal group, model group, positive drug group, salt-processed Psoraleae ructus group, raw Psoraleae Fructus group, Buguzhi Pills (salt-processed Psoraleae Fructus + salt-processed Foeniculi Fructus) group and three kinds of simulative Buguzhi Pills groups (salt-processed Psoraleae Fructus + raw Foeniculi Fructus; raw Psoraleae Fructus + salt-processed Foeniculi Fructus; raw Psoraleae Fructus + raw Foeniculi Fructus). A complex method of hydrocortisone and sennae folium was adopted to establish the diarrhea model due to spleen-kidney yang deficiency. After administration, the organ indexes of thymus, spleen, kidney, adrenal gland, and testis were measured; The pathological changes of corresponding organs were observed; The serum levels of motilin and testosterone were detected by ELISA. Results: Compared with the normal group, the food intake and body weight reduced; The organ indexes decreased in varying degrees; The above organs showed obvious pathological changes under the microscope; the level of motilin showed an upward trend, and the level of testosterone decreased significantly in model group. The above symptoms and indicators were improved in varying degrees after administration, and the effect of Buguzhi Pills was better than that of Psoraleae Fructus alone and three kinds of simulative Buguzhi Pills on the whole. Conclusion:The efficacy of Buguzhi Pills on warming kidney-spleen yang and relieving diarrhea was superior to that of Psoraleae Fructus alone, and the antidiarrheal effect can be enhanced by salt-processing.
