Adenosine is an endogenous nucleoside which stimulates respiration in man and other mammals. In animals adenosine appears to initiate respiratory stimulation within the carotid body, but whether this is the site of action in man is not known. We administered adenosine by intra-aortic infusion to 12 subjects undergoing cardiac catheterisation. When adenosine was infused at three sites proximal to the carotid circulation, minute ventilation was significantly higher than baseline values or those during adenosine infusion at a more distal site. These results support the hypothesis that adenosine-induced respiratory stimulation in man is mediated in the carotid body.
腺苷是一种内源性核苷,可刺激人类和其他哺乳动物的呼吸。在动物体内,腺苷似乎在颈动脉体中引发呼吸刺激,但这是否是其在人体内的作用部位尚不清楚。我们通过主动脉内输注向12名接受心导管检查的受试者给药腺苷。当在颈动脉循环近端的三个部位输注腺苷时,分钟通气量显著高于基线值或在更远端部位输注腺苷时的值。这些结果支持了这样一种假说,即腺苷在人体内引起的呼吸刺激是由颈动脉体介导的。
