[Pharmacology of cellular ischemia].
Knowledge of cellular disturbances provoked by an ischemic aggression conditions the use of a pharmacologic strategy that could possibly protect the cell from necrosis. Whatever the type of cell, the basic mechanisms are very similar: energy failure, acidosis, loss of electrolytic homeostasis, particularly of calcium, formation of free radicals and, of more recent knowledge, genetic induction. Different molecules have been shown to be effective at each of these stages in one or other of the many experimental models available. The therapeutic approach is not very forthcoming at present but the field of applications is vast. Ischemic disease is not restricted to cerebral or cardiac ischemia and, although the lesions are mainly those of senescence, it is observed in other etiologic frameworks, if only in the perinatal period. Finally, the great increase in the use of organ transplants opens up another field of application with research on the best method for organ preservation and optimization of its acceptance by the host organism.
