[Cyclosporin A-sensitive mitochondrial pore as a target of cardioprotective action of hydrogen sulfide donor].

In experiments on a model of ischemia-reperfusion in Langendorff isolated rat hearts and isolated mitochondria we studied the role of hydrogen sulfide donor - sodium hydrosulfide (NaHS, 7.4 mg/kg) in modulating the sensitivity ofmitochondrial permeability transition pore opening. It was shown that NaHS increased the reserves of rat myocardium and had cardioprotective effects from ischemia-reperfusion.
