摘要

研究了鲤鱼在暴露于空气中时，其膀胱作为辅助呼吸器官的可能性。正常动物暴露于空气后，血液pH、pO2和平均膀胱O2浓度降低，血液pCO2升高。气管结扎后暴露在空气中会导致血液pH值和二氧化碳分压升高，血液pO2和膀胱二氧化碳浓度降低。讨论了这些观察结果的可能原因。

The survival of carp (Cyprinus carpio) outside water.

The possible use of the swimbladder of carp as auxiliary respiratory organ when the animals are exposed to air has been studied. After exposure to air, blood pH and pO2 and mean swimbladder O2 concentration decrease and blood pCO2 increases in normal animals. Exposure to air after ligation of the pneumatic ducts results in increases in blood pH and pCO2 and decreases in blood pO2 and swimbladder carbon dioxide concentration. Possible reasons for these observations are discussed.
