Résumé du colloque

A variety of information has been collected about the aging red blood cells (RBC) and their membranes. The RBC can lose a large part of their acetylcholinesterase (AchE) without undergoing much hemolysis or they may undergo a high degree of hemolysis without much loss of their AchE. Formation of methemoglobin has been observed to stimulate the process of hemolysis. However, formation of methemoglobin opposes the release of AchE from the RBC or their membranes. The AchE released from the RBC are present in macro-molecular form. The amounts released being higher the lower the temperature of incubation is, especially below 20°C. Besides, there is only a limiting amount of RBC AchE or their membrane AchE that can be lost in this way. Contrary to the common belief, it has been observed that there is nothing called intracellular soluble AchE in the red blood cells.
