Endpoint implementation of reactions initiated by ischemia is the mitochondrial transition pore permeability. Mitochondria pores opening results in a release of factors triggering apoptosis. primarily the cytochrome С Inhibition of the pores opening protects ischemic damage of the cells. The key enzyme regulating the mitochondrial permeability transition pore is glycogen synthase-kinase 3b (GSK-3b): the phosphorylation of the enzyme inactivates the enzyme and prevents pore opening. We have shown in previous study that preconditioning with sevoflurane increases the content of the phosphorylated form of 6SK-3b and protects the mitochondria of neurons in rats brain during ischemia/reperfusion. Aim of studi is to determine content of the phosphorylated GS K-3b in neurons of rat brain in the model of total ischemia/reperfusion influenced by: 1 MAC desflurane vs control group; 1 MAC desflurane vs 1 MAC sevoflurane and 1 MAC desflurane vs training ischemia.
