Evidences for the existence of glycoproteins and mucopolysaccharides metabolic cycles in the cerebellum of birds and mammals.

Abstract

Cerebellum glycoproteins of rats and ducks are studied using sugar-specific agglutinins. It is used the Con A-Peroxidase-DAB technique described by Bernhard and Avrameas (1971). Other agglutinins (Tetragonolobus Purpureus Lectin, Wheat Germ Agglutinin and Soybean Agglutinin) fixed to Peroxidase according to the technique of Gonatas and Avrameas (1973) are also used. The techniques for mucopolysaccharides as described Martínez-Rodriguez et al., (1976) are carried out as well. By means of all these techniques, results that suggest the existence of metabolic cycles in Purkinje cells are obtained.Peer Reviewe
