A relationship between body fat and plasma pseudo-cholinesterase.

The aim of this study was to determine whether there was any relationship between body fat and pseudo(or plasma) cholinesterase. Hutchinson, McCance & Widdowson (I~sI), in reporting their studies of undernutrition and feeding, pointed out that, at the end of rehabilitation when men became ‘fat’, the average pseudo-cholinesterase was higher than normal. It therefore seemed of interest to investigate the relationship of body fat to pseudo-cholinesterase in men in metabolic equilibrium as opposed to that in men at the end of a dynamic process of equilibrium.
