abstract：:1. Rat pups were gestated and born in normoxia (inspired O2 pressure 149 mmHg) or chronic hypoxia (insured O2 pressure 80 mmHg) to test whether chronic hypoxia alters carotid body glomus cell calcium currents. Carotid bodies were removed from 5- to 8-day-old-pups under halothane anesthesia, at which time blood hematoc...
