Assessment of ethylthiobenzimidazole and fabomotizole activity in a model of hypercapnic hypoxia with cutting off the brain hemispheres work

BACKGROUND: Resistance to hypoxia depends on the type of animal, its condition (fatigue, pre-exposure, pregnancy in females) and the conditions of the experiments. AIM: study the effect of ethylthiobenzimidazole (Metaprot, Bemityl) and fabomotizole (Afobazole), which were antihypoxants with an isothiourea group, on the resistance of male outbred mice to acute hypoxia with hypercapnia under conditions of isolated functioning of one of the cerebral hemispheres. MATERIALS AND METHODS: Acute hypoxia with hypercapnia was simulated by the cupping method by placing male mice in a closed hermetic volume (200 cm3) until the death of the animal. Previously, in some mice, one of the cerebral hemispheres was temporarily switched off according to the Leao method. RESULTS: It has been shown that ethylthiobenzimidazole and fabomotizole, administered intraperitoneally in equimolar doses (25 and 32.8 mg/kg, respectively) 30 min before a hypoxic episode, increase the life time of experimental animals when either of the hemispheres (right or left) is turned off approximately equally. CONCLUSIONS: Data are considered in terms of the possibility of using both drugs in the prevention and treatment of ischemic strokes.
