Modifications of some enzyme activities in parotid tissue homogenates have been studied in animals which were also examined for morphological changes and for plasma and parotid amylase activity. Results from irradiated animals show a certain increase in maltase activity. Alkaline phosphatase and LAP show no significant variations; a similar behaviour is shown by lysosomal enzymes and protein content. A different pattern was seen by comparing the curves of these enzymes with those of the same activity in the small intestine. This result appears to be due to the different radiosensitivity of these tissues.

Alkaline phosphatase, LAP, beta-glucuronidase and cathepsin D activities and protein content of the kidney homogenate did not show any circadian rhythm in animals sacrificed at different hours of the day. The fluctuations of maltase appear modest and not dependent on a ligh/dark cycle.

The behaviour of some activities of the kidney was studied both in young-adult and in adult rats exposed to an 8-Gly dose of gamma-rays and killed at various intervals after irradiation (both in the morning and in the evening). Brush border and lysosomal enzymes did not show marked differences among control rats of the same age even if adult animals showed levels of maltase, alkaline phosphatase and LAP activities higher than the young-adult group. Moreover, irradiation did not induce typical modifications of the same enzyme activities in young-adult and adult rats. Adult animals showed a reduction in the brush border enzyme activities at 120 hours after irradiation while, at the same interval, lysosomal activities underwent an increase both in young and in adult animals.
