Cobalt-activated acylase activity in experimental toxic liver damage.

Co++-activated acylase activity was studied in the blood serum and liver homogenates from rabbits poisoned with CCl4 in doses of 0-5 g/kg body weight intraperitoneally. Activity of this enzyme in serum increased on the first day after poisoning, but the rise was of short duration. Increased serum activity of the enzyme was accompanied by an increase in acylase activity in liver homogenates, which persisted to the ninth day, i.e. to the end of the observation period, when serum acylase activity returned to normal. Co++-activated acylase activity in serum was not correlated with its activity in liver homogenates. Co++-activated acylase activity was significantly correlated with AlAT and GGTP activities, but acylase and LAP were not correlated.
