Abstract

               The sublingual salivary gland of Malayan pangolin(Manis javanica) was investigated by using conventional and lectin histochemical methods in combination with enzyme digestion procedures. The results showed both mucous and serous cells in secretory endpieces of sublingual
salivary gland. Mucous cells showed a large number of vicinal diol groups with acid and neutral glycoconjugates. Lectin histochemistry gave evidence of the presence of mannose, α N-acetylgalactosamine, N- acetylglucosamine and sialic acid linked to Galactosyl (β1→3) N –acetylgalactosamine residues.

                Serous cells had positive reaction with almost all the conventional employed, with the exception of acid glycoconjugates which were less diffused. Serous cells secreted predominantly neutral glycoconjugates with mannose, Galactosyl (β1→4 ) N- acetylglucosamine, N-cetylglucosamine and fucose residues.
