Abstract:
Objective To observe rat plasma angiotensin Ⅱ (AⅡ) content change after exposed to infrasound. Methods Infrasound was exposed to rats for 1,7,14,21 d and two hours every time in a day. After half, six, twelve, eighteen and twenty-four hours, AⅡcontent change was observed. Results After exposed to infrasound for 1 d,AⅡcontent continued to increase in the next twenty-four hours compared to control group (P<0.01).After infrasound exposure for 7 d,AⅡ began to increase after half hour compared to control group(P<0.01), reached maximum at twelve hours, then began to decrease and turned less than that in the control group at twenty-four hours(P<0.05).After infrasound exposure for 14 d, AⅡ increased significantly compared to the control group(P<0.01).At six hours and twelve hours,there was no significant difference(P>0.05),it increased notably at eighteen hours and twenty-four hours(P<0.01).After infrasound exposure for 21 d, AⅡ began to increase at half hour compared to the contol group(P<0.05),reached maximum at twelve hours,then began to decrease and showed no significant difference at twenty-four hours(P>0.05).Conclusion After infrasound exposure, there was irregular change of rat plasma AⅡ content at different times.
