title: Histochemistry of mucosubstances in the mantle of fresh water mussel, Parreysia corrugata var. nagpoorensis (Lea) II. Mucosubstances of the middle marginal fold.
abstract: The results of the various histochemical reactions on mucosubstances indicate that in the middle fold of the mantle edge two types of mucus cells exist, one producing sulphomucins and the other neutral mucosubstances. The cells secreting neutral mucosubstances are few in number. The sulphated mucus is strongly alcianophilic. The alcianophilia persists when the tissues are stained with alcian blue in concentration up to 0-5 M magnesium chloride. Testicular hyaluronidase has no effect on the staining pattern of the mucus.
