title: [The effect of heat exposure on the circadian rhythm of the enzymatic activity in different sections of the rat small intestine].
abstract: Two-hour heat exposure (40-41 degrees C) was shown to change the circadian rhythms of enteral gamma-amylase, maltase and sucrase activities. The character and obviousness of the changes depended on the type of enzyme activity and the portion of the small intestine. The heat exposure did not change daily mean levels of enzymatic activities and their distribution along the small intestine.
