Acetylcholinesterase activity in chronic renal failure.

Twenty healthy subjects and 39 Chronic Renal Failure patients (CRF-patients) maintained on chronic hemodialysis were used in this investigation to study the changes in acetylcholinesterase (AChE) activity of red blood cells (RBCs). The CRF-patients were all undergoing hemodialysis treatment. AChE activity from the CRF-patients was determined before and after dialysis.

Acetylcholinesterase: an enzymatic marker of human red blood cell aging.

The purpose of this investigation was to determine whether acetylcholinesterase (AChE) can be used as a marker of cell aging in human red blood cells (RBCs). This study used consented subjects; both males and females in an age range of 21-42 years. The blood samples (8-9 mL) were drawn in tubes containing sodium heparin or EDTA as anticoagulants.
