Effect of Potassium Comenate on CNS Functional Status in Rodents Exposed to Combined Hypoxia and Hypercapnia in Comparison with Normally Ventilated Animals

Аннотация

The effects of potassium comenate on functional state of CNS in mice and rats were studied in the open-field and hole-board tests under control conditions and after acute exposure to hypoxia–hypercapnia. The effects of potassium comenate on CNS were also studied in rodents subjected to propofol-induced sleep. Preliminary administration of 4 mg/kg potassium comenate for 3 days attenuated the posthypoxic changes in behavioral reactions (emotional anxiety/reactivity). The pronounced stress-protective effect of potassium comenate was observed both on days 1 and 14 after exposure to hypoxia–hypercapnia. Under normal conditions, potassium comenate moderated behavioral reactions and augmented somniferous effect of propofol. We hypothesized that the antihypoxic effect of potassium comenate is determined by its stress-protective and sedative potencies.
