Abstract:
AIM: To investigate the changes of hemodynamic parameters and ECG in circulatory failure rats induced by organophosphate insecticides DDV and parathion.METHODS: Healthy Wistar male rats,weighing(320?20)g,were treated with organophosphate insecticides by ip.to induce circulatory failure.When the mean blood pressure(MBP) decreased to 45 mmHg,the changes of hemodynamic parameters and ECG were observed.RESULTS: In circulatory failure rats,SBP,DBP,MBP,HR,LVDP,IP,+dp/dtmax,-dp/dtmax,Vpm and +dp/dtmax/IP changed dramatically(P
