[Quantitative determination of the vascular volume of the cat carotid body under normoxia, hyperoxia, hypoxia and hypercapnia (author's transl)].

The ratio vascular volume to total volume was quantitatively analyzed in the cat's carotid body in dependence on the oxygen content of respired air and arterial pO2, respectively. Under hypoxia the vascular volume was 50% higher than under hyperoxia. This connection was ascertained after both perfusion fixation and immersion fixation.
