Studied was the activity of low concentrations --- 1-10-12, and 1.10-18 -- of the specific reactivators of the enzyme cholinesterase (ChE): 2-PAM, TMB-4(Trimedoxime) Toxogonin, HS-3, and HS-6, in a chromodacryorrhea test (ChDT) with rats, daily (in the course of 30 days -- 1 ml/100 g), twice (at an interval of 10 days -- 1 ml/100 g) and once (5 mg/kg) at subcutaneous application. Described is an activating affect (observed for the first time in vivo) on ChE preduced by low and very low concentrations of reactivators of the group of oximes. HS-3 produced best activating effects. The low concentrations of the specific oxime ractivators of ChE, followed up by ChDT, can be used as sensitive quantitative indicators of the activity of ChE. They can also serve to specify the mode of action power and term of effectiveness of these reactivators.
