Effects of 60Co gamma-irradiation of mice on the temporal changes of acid phosphatase activity in spleen and liver.
Acid phosphatase activity and protein content of spleen and liver, and organ weight of whole-body 10 Gy 60Co gamma-irradiated mice were measured every four hours during a 24-hour period. In irradiated mice, in comparison with those non-irradiated, increased acid phosphatase activity in spleen related to both 1 mg of protein at 20.00I, 04.00, 08.00, 12.00, 16.00 and 20.00II and 1 g of fresh tissue at 20.00I, 08.00, 12.00, 16.00 and 20.00II; decreased weight of spleen and protein amount in spleen during the whole 24-hour period, as well as fluctuations in all the parameters measured in spleen, except the level of protein related to 1 g of fresh tissue, were observed. In irradiated mice, compared with the controls, the increased acid phosphatase activity in liver calculated per both 1 mg of protein at 24.00, 08.00 and 16.00 and 1 g of fresh tissue at 08.00 and 16.00; the decreased protein concentration in liver related to 1 g of fresh tissue and the whole organ weight at 12.00, as well as temporal changes in the protein level in liver expressed per 1 g of fresh tissue, were found. 60Co irradiation of mice influenced the acid phosphatase activity and protein concentration in liver are less than in spleen.
