The effect of starvation of the pseudo-cholinesterase activity of the liver and serum of rats

Abstract

The amt. of pseudo-cholinesterase in the livers of adult male rats decreased from 96 to 70 units/100 g. initial body wt. during a 6-day fast, but activity per g. liver changed very little, and the activity in the serum enzyme remained constant at 7.1 units/ml. Two days'' starvation reduced the total pseudocholinesterase in the livers of female rats from 330 units/100 g. initial body wt. to 110, and 6 days'' starvation to 96. There was little change per g. liver after the 2d day. Activity in the serum fell from 41 to 23 units/ml. in the 6 days.
