Summary

In the acute hypoxic conditions, the presence of argon in the gaseous mixtures is able to increase the survival of laboratory animals (rats). The purpose of the work was to estimate the influence of argon-containing hypoxic and hyperoxic gaseous mixtures on the embryogenesis of Japanese quails (Coturnix coturnix japonica). The Japanese quail eggs were incubated in hermetic chambers with different gaseous mixtures.
The total mortality of embryos of Japanese quail chicks was observed in the hypoxic (10 % O2) oxygen-nitrogen and oxygen-nitrogen-argon gaseous mixtures not later than on day 7 of the development stage. These mixtures are teratogenic. However, the presence of argon in the mixture (about 55 %) led to the complete absence of such defects, as microcephalia, and a halving of other pathological manifestations. A hyperoxic oxygen-nitrogen gaseous mixture (35 % O2) led to the retarded development of embryos (67 % of cases). A similar oxygen-nitrogen-argon mixture was caused an accelerated development of embryos (33 % of cases).

Key words: Coturnix coturnix japonica; embryogenesis; hypoxia; hyperoxia; gaseous mixtures; argon
