RESUMEN

To investigate the effect of patchouli alcohol on inhibiting Helicobater pylori urease activity, and its effect on expression levels of related genes, and lay the foundation for further research on the effect of patchouli alcohol on H. pylori colonization and infection. H. pyloriwas cultured and identified by gram staining, rapid urease test (RUT) and PCR method. Then agar dilution method was used to detect the bacterial survival after 1 h intervention by different concentrations of patchouli alcoholin the acidic (pH 5.3) and neutral (pH 7.0) conditions; berthelot method was used to detect urease activity and RT-qPCR method was used to detect the expression changes of ureA, ureB, ureE, ureH, ureI, and nixA related urease genes. The results showed that the survival rate of H. pyloriwas not significantly changed but the urease activity was obviously decreased after intervention by different concentrations of patchouli alcohol; meanwhile, the expression levels of ureA, ureB, ureE, ureH, ureI, and nixA were decreased to different degrees. Therefore, patchouli alcohol could inhibit H. pylori urease activity in both acidic and neutral conditions, and the mechanism may be related to down-regulation of urease gene expression.

RESUMEN

AIM To investigate the improving effect of Suoquan Capsules (Linderae Radix,Alpiniae oxyphyllae Fructus and Dioscoreae Rhizoma) on mice with diabetic cystopathy and its mechanism of action.METHODS Sixty mice were randomly assigned into normal group (n =8) and model group (n =52);the diabetic models of the latter were induced by high-fat feeding combined with streptozotocin (STZ) injection,then modeled mice (n =32) were randomly divided into model,Mecobalamin Tablets,low-and high-dose Suoquan Capsules groups.The influences of Suoquan Capsules on fasting blood glucose (FBG),glycated serum protein (GSP) level and general conditions were observed.The bladder leak point pressure (BLPP) was determined.Histopathological staining was performed on urinary bladder.And the expressions of substance P and NK1 receptor were detected by double immunofluorescent staining.RESULTS There were no significant differences in FBG,GSP,body weight,food intake and water consumption among various groups.The high-dose Suoquan Capsules significantly decreased urine volume of mice.Compared with the model group,the treatment with Suoquan Capsules markedly increased BLPP,the expressions of substance P and NK1 receptor were significantly increased,and the histopathology of bladder in mice was obviously improved.CONCLUSION Suoquan Capsules improves the diabetic cystopathy in mice,and its mechanism maybe related to the up-regulation of substance P and NK1 receptor expressions in bladder tissue.
