[Comparative evaluation of the toxicity of potassium hydrocarbonate and potassium chloride].

The potassium hydrocarbonate and potassium chloride toxicity was compared in experiments on 113 albino rats. The death following introduction of maximal amounts of potassium chloride was noted to supervene earlier than it did in animals receiving equivalent doses of potassium hydrocarbonate. Simultaneous introduction of sodium hydrocarbonate lowered the toxicity of both potassium hydrocarbonate and chloride. Morphological investigations revealed that toxic doses of potassium hydrocarbonate bring about shifts in the carbohydrate and lipids metabolism. Some mechanisms behind the action produced potassium chloride and hydrocarbonate are discussed.

[Patterns in the change in the body state of dogs during a breakdown of the atmosphere regeneration system in a pressurized space].

Experiments were carried out on dogs kept in a sealed chamber. Changes in the O2 and CO2 concentrations as well as variations of physiological functions, the so-called survival curves, were studied under the conditions of terminated O2 supply and CO2 utilization. The criteria of investigation, mathematical and physiological analysis were chosen from the point of view of predicting hazardous states during failures of the environmental control system. Tolerance limits during slow and rapid changes of the environment, phases of changes of the body state and mechanisms of a combined effect of increasing hypercapnia and hypoxia were considered.
