Abstract:
This work compared the preventive and therapeutic effect of verapamil and anisodamine on anoxia-reoxygenation injury (oxygen paradox) of isolated rat heart performed with Langendorff apparatus. Results showed that addition of anisodamine (1.64?10~(-4)M) or verapamil (5?10~(-8)M) to the perfusion fluid during anoxic period significantly ameliorated the anoxia-reoxygenation injury of the heart; e. g., the recovery of cardiac functions, the improvement of myocardial acidosis, the decrease in leakage of LDH from myocardium, and in the accumulation of lipid peroxides and calcium. When the drugs were given during the period of reoxygenation, anisodamine was very effective too, but verapamil had no effect. From these results it may be suggested that anisodamine has more extended anti-oxygen-paradox effect in ddition to calcium channel blocker action.
