The work reported here examines the quantitative ultrastructure of cat carotid body type I cells, and the effects of hypoxia on the cells. On the basis of size and density of electron-dense cored vesicle (EDCV) we were unable to identify more than one major population of type I cells. Prior ventilation of the animals with 10% O2 resulted in an increase in the volume percentage (Vv%) of mitochondria and a decrease in the Vv% of EDCV as compared to the values after ventilation with 100% O2. The lack of effect of prior denervation of the carotid body on the hypoxic changes suggests that the effects are not mediated via an efferent pathway.
本文所报告的研究工作考察了猫颈动脉体I型细胞的定量超微结构以及缺氧对这些细胞的影响。根据电子致密核心囊泡（EDCV）的大小和密度，我们无法识别出超过一种主要类型的I型细胞。与用100%氧气通气后的数值相比，预先用10%氧气对动物进行通气会导致线粒体的体积百分比（Vv%）增加，而EDCV的Vv%降低。预先对颈动脉体进行去神经支配对缺氧变化没有影响，这表明这些影响不是通过传出途径介导的。
