| Popis: | The pharmacotherapy of hypoxia is an important task of modern experimental and clinical pharmacology. The medications with anti-hypoxic effect implemented into clinical practice unfortunately do not meet requirements of physicians due to poor efficiency, narrow range of active dosages and undesirable side effects. The complexes of zinc with N-alkenylimidazole demonstrated anti-hypoxic activity at various models of acute hypoxia within large range of dosage. Therefore, further studying of zinc-contained compounds as possible correctors of hypoxia is of particular interest. The experiments with white nonlinear male mice were used for comparative investigation of ant-hypoxic effect of complex compounds of zinc acetate with N-propargylimidazole and 3-hydroxipyridine, including complexes immobilized on sulfated arabinogalaсtan and also well-known anti-hypoxants and/or anti-oxidants: etomerzol, mexidol, nooglutil and hypoxen. It is demonstrated that anti-hypoxic effect of complex of zinc acetate with N-propargylimidazolein conditions of acute hypobaric hypoxia, acute hypoxia with hypercapnia acute hematic hypoxia by width of active dosages (1-100 mg/kg, intraperitoneally) and degree of expression (19-317% in comparison with control groups of animals) excels the similar effect in well-known anti-hypoxants and/or anti-oxidants: etomerzol (25-100 mg/kg, intraperitoneally), mexidol (100 mk per kg, intraperitoneally), nooglutil (25-100 mg/kg, intraperitoneally) and hypoxen (50-150 mg/kg, intraperitoneally). The protective effect of complex of zinc acetate with 3-hydroxipyridine by width of active dosages (25-100 mg/kg, intraperitoneally) and degree of expression (27-167% in comparison with control groups of animals) in conditions of exogenous hypoxia (acute hypobaric hypoxia and acute hypoxia with hypercapnia) excels similar effect of etomerzol and mexidol ans is comparable with effect of nooglutil and hypoxen. The complexes immobilized on sulfated arabinogalactan were ineffective. |
