[A study of histochemical and morphological indices in the alimentary canal of the rat exposed to food fibers].

No one would at present call in question the importance and necessity of using vegetable food fibre (as isolated biopolymers, such as lignin, cellulose, hemicellulose, pectin substances forming a part of a complex of food fibre or adding the latter to conventional foodstuffs) in everyday diet of man. The conducted experimental investigations have shown that the studied kinds of food fibre do not affect hemopoiesis, they are not toxical, animals tolerate these well, which facts warrant their usage as dietary supplementation in man.
