title: Histochemical study of mesenteric lymph nodes in old rats.
abstract: The main positive reactions in the large mononuclear cell occurring in some nodes were shown with PAS, alcian blue, Sudan black B and acid haematin. The results suggest that in these cells, considered to be mononuclear phagocytes, there is a storage of hexose-containing mucosubstances, acid mucopolysaccharides and choline-containing phospholipids.
