Morphological and Histochemical Study of Cephalic Glands ofBothrops jararaca(Ophidia, Viperidae)

Morphological and histochemical studies of the cell types in the cephalic glands of Bothrops jararaca have been performed. It is concluded: 1) mucous cells are found in the salivary labial, accessory glands; mucous-serous cells are found in the salivary labial, accessory and Harderian glands; serous-mucous cells are found only in the venom gland; 2) neutral mucosubstances and protein were found in the salivary labial, venom, accessory and Harderian glands; 3) hyaluronic acid was detected in the Harderian gland; 4) of the to sulfated acid mucosubstances, only chondroitin sulfate B was detected in the salivary labial and accessory glands; 5) sialic acid was detected in the salivary labial, accessory and Harderian glands.
