Action de différents mélanges gazeux sur l'artère mésentérique de l'embryon de poulet explantée in vitro

Summary

The effect of various gas mixtures on the mesenteric artery of chicken embryo explanted in vitro has been studied. The expiants were cultivated in normal air, with addition of 3% of CO₂, and in hypo- and hyperoxic atmosphere. The best survival of explanted arteries is obtained with atmospheric air. The hypoxic gas mixture (2% O₂) has the most toxic effect on the expiants. The hyperoxic conditions show also a toxic effect, but in a lesser degree than hypoxic conditions.
