title: Developmental characteristics of histamine methyltransferase and phenylethanolamine-N-methyl-transferase of rat brain.
abstract: The specific activity of histamine methyltransferase of rat brain increases rapidly from the 16th until the 25th day of gestation (7 days after birth). The specific activity of phenylethanolamine-N-methyl-transferase shows a rapid increase during the 1st and the 2nd week after birth, the adult values being obtained by the end of the 2nd week.
