title: [Blood and cardiac cholinesterase activity in rats of different sexes and ages during muscle loading and hypokinesia].
abstract: The activity of acetylcholinesterase (Ache) and butyrilcholinesterase (Bche) in the blood and the heart of 3 and 13-month old control male rats is considerably lower than in female rats. In old rats (25 months) no sex differences in the Ache and Bche were revealed in the heart. In 3 and 13-month old male and female rats, under conditions of muscular exercises, the Ache and Bche activity is lower, and in hypokinetic male rats--higher than that in respective control animals. In all the rats, irrespective of sex, age and motor conditions, the Ache and Bche activity tended to decrease, in direction from the sino-atrial node to the heart apex.
