title: [Circadian rhythmicity of the enzyme activity in the small intestine of growing, adult and old rats].
abstract: The circadian rhythms of lactase, sucrase and dipeptide hydrolase from homogenates of the small intestine mucose are unequal in different age. The amplitude of diurnal fluctuation is reduced in adult and, particularly, in old rats.
