To evaluate the oxygen dependence of chick embryos at high and low oxygen concentrations, the gas exchange of embryos was measured with an oxygen consumption measuring apparatus. Oxygen consumption and the lipid peroxide levels in the blood, heart, and liver of chick embryos were measured after exposure of the embryos on the 13th day to high or low concentrations of oxygen (15-100%). Exposure to low concentrations (15-20%) resulted in a marked depression in oxygen consumption during the exposure time, which was followed by an increase in consumption to a level near the control. After exposure to high or low concentrations, a significant decrease in consumption was seen from day 14-21. A close relationship between oxygen consumption and the lipid peroxide level was observed in the blood of chicks on the 21st day.
