Effects of carotid glomectomy on erythron parameters in rats differing in the resistance to acute hypoxia

Rats with low resistance to acute altitude hypoxia did not differ from those with high resistance in the erythron parameters recorded under normal environmental conditions. After a bilateral carotid glomectomy, significant falls in the red blood cell count, hemoglobin concentration, packed cell volume, and mean corpuscular hemoglobin were recorded only in the group with low resistance to acute hypoxia, although the "altitude" resistance was decreased to similar degrees in the two groups. ©1996 Plenum Publishing Corporation.
