Effect of various fish meals on disaccharidases and alkaline phosphatase of the small intestine in rats

Abstract

Female rats of the Wistar strain, weighing 40-060 g were used to study the effect of fish meals (Coryphaenoides rupestris, Chimaera monstruosa and Merluccius merluccius) on the disaccharidases and alkaline phosphatase in the small intestine in relation to the control group which consumed casein.Fish meal diets diminished lactase and alkaline phosphatase activity, the latter being most remarkable in animals fed Ch.monstruosa meal, while no statistical variations in maltase and sucrase activity were observed.Maltase, sucrase and lactase activity of animals fed Ch.monstruosa meal dropped in comparison with those fed C.rupestris meal, while the alkaline phosphatase activity showed no significant changes.
