Abstract
Rabbits anesthesized with urethan and subjected to mild hypoxia (60-70 Torr arterial PO2) through a reduction of the minute volume were injected with a carotenoid compound, crocetin, or saline. The increased PO2 in the arterial blood seen subsequently with crocetin is attributed to increased diffusion through plasma. Blood flow rates remained constant and were unaffected by crocetin.
摘要
用氨基甲酸乙酯麻醉的兔子，通过减少分钟通气量使其处于轻度缺氧状态（动脉血氧分压为60 - 70托），然后给它们注射类胡萝卜素化合物藏红花酸或生理盐水。随后观察到，注射藏红花酸后动脉血中氧分压升高是由于通过血浆的扩散增加所致。血流速率保持恒定，不受藏红花酸影响。
