Erythrocyte Acetylcholinesterase Activity Changes in the Early Stages of Anemic and Hypobaric Hypoxia or after CoCI2 Treatment in Rabbits

Abstract

The changes of erythrocyte acetylcholinesterase (AChE) activity in rabbits, respectively, subjected to bleeding, hypobaric hypoxia and CoCl2 treatment were studied. In such conditions a rise of the enzyme activity was observed. Similar increases also take place as a consequence of i.v. infusions carried out by using lactic or hydrochloric acid. These increases in the erythrocyte AChE activity may be connected with the decrease of the PCO2 [partial pressure of CO2] that occurs in the various experimental conditions achieved.
