[The importance of hypothermia in the preconditioning increase of ischemic tolerance to global cerebral ischemia].
Various types of preconditioning including the main hypoxia (hypoxic, circulatory, hematic/hypemic and tissue/histotoxic), agonists of adenosine A-receptors and openers of K(ATP)-channels induce a hypothermia. A-agonists act through A1-receptors, CoCl2 and NiCl2--via endogenous adenosine and activation by it A1-receptors. The developing hypothermia correlates with neuroprotective effect and is important, but not the only mechanism of tolerance increase to global ischemia. At the similar hypothermia the preconditioning effect excels more frequently an influence of external cooling.
