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.
