Respiratory Function of Blood of the Avians
鳥類血液之呼吸功能
摘要
血液收集自鴿八隻、雞二隻及鵝四隻翅膀靜脈。用氧解離曲線分析儀分析血液氧解離曲線，並用血液氣體分析儀分析血液酸鹼度、二氧化碳分壓及氧分壓，計算重碳酸根離子。用血球自動計數儀計數紅血球、白血球及分析血色素與測定血球血漿比量，以及分析血液2，3-DPG、三燐苷酸、乳酸及丙酮酸等。其正常數值統計報告如表一。 由實驗資料分析，鳥類血液50%氧飽和度之PO2（即P50）較人類爲大，卽血氧解離曲線較人類偏右。其血紅素與氧親和力較低，血液較易放出氧。

Chiang, S. T., W. F. Tzeng, S. C. King and P. Y. Lee.: Respiratory function of blood of the avians. Chinese J. Physiol., 22(4): -133-140, 1978. Individual blood samples were collected from wing veins of eight adult pigeons, two adult chickens and four adult geese and were analyzed for oxygen dissociation curves by hemo-scan, an instrument measuring PO2 and O2 saturation simultaneously. The findings agree with the common belief that avian blood in general has a low affinity for oxygen. Blood pH, PCO2, concentration of 2, 3-DPG, lactic acid, pyruvic acid, red blood cell, hemoglobin and hematocrit were also determined, the related parameters have been calculated. Normal values of those variables are reported and the possible effects of some of those parameters on oxygen affinity are postulated.
