Abstract
The choline acetyltransferase activity underwent marked changes during the life span: in the submaxillaries, the total enzyme activity increased 70-fold from birth up to the age of 3 mo. and it then remained constant throughout the rest of the observation period, i.e., up to 28-29 mo.; in the parotids, in contrast, it continued to rise beyond the age of 3 mo. and the highest value was reached at 24 mo. The weights of the glands increased markedly up to 3 mo. The gain in weight was less pronounced thereafter.
