1Acute effects of Helicobacter pylori extracts on gastric mucosal blood flow in the mouse显示文摘AIM: To investigate the mechanisms underlying the reduction in gastric blood flow induced by a luminal water extract of Helicobacter pylori (HPE). METHODS: The stomachs of isourane-anesthetized mice were exteriorized, and the mucosal surface exposed. Blood flow was measured with the laser-Doppler technique, and systemic arterial blood pressure monitored. C57BL/6 mice were exposed to water extract produced from H pylori strain 88-23. To investigate the role of a nerveor iNOS-mediated pathway, we used intraluminal lidocaine and iNOS-/-mice. Blood flow response to the endogenous nitric oxide synthase inhibitor asymmetric dimethyl arginine (ADMA) was also assessed. RESULTS: In wild-type mice, HPE decreased mucosal blood flow by approximately 30%. This reduction was abolished in iNOS-defi cient mice, and by pre-treatment with lidocaine. Luminally applied ADMA resulted in reduction in blood flow similar to that observed in wild-type mice exposed to HPE. CONCLUSION: A H pylori water extract reduces gastric mucosal blood flow acutely through iNOS- and nerve-mediated pathways.Johanna Henriksns Christer Atuma Mia Phillipson Stellan Sandler Lars Engstrand Lena Holm 2009World Journal of Gastroenterology2009,15,2:2
