SUMMARY
The authors present morphological, morphometric and histochemical study of the salivary glands of the Colubridae Leimadophis viridis (Günther, 1862) (Ophidea). Based on the results, the authors concluded: (i) the acini of supralabial, infralabial and premaxillary glands are formed by mucous and mucoserous cells; Duvernoy's gland by seromucous cells; (ii) mucous cells show neutral and sulphated mucosubstances and sialic acid. Mucoserous cells show a neutral mucosubstance, sialic acid and protein radicals. Seromucous cells of Duvernoy's gland show a neutral mucosub- stance and protein radicals. The acinar area, height of tubule and duct cells, and nuclear volume of acinar, tubule and duct cells were evaluated morphometrically.
RESUMO
Os autores estudaram morfológica, morfométrica e histoquimicamente as glândulas salivares do colubrideo Leimadophis viridis (Günther, 1862) (Ophidea). Baseados nos resultados, os autores concluiram: (i) os ácinos das glândulas supralabial, infralabial e premaxilar são formados por células mucosas e muco-serosas; a glândula de Duvernoy é formada por células sero-mucosas; (ii) as células mucosas apresentam, no seu produto de secreção, mucossubstâncias neutras e ácidas sulfatadas, além de ácido siálico. As células muco-serosas apresentam mucossubstâncias neutras, ácido siálico e radicais protéicos. As células sero-mucosas da glândula de Duvernoy mostram mucossubstâncias neutras e radicals protéicos. Foram calculados morfometricamente a área acinar, a altura das células dos ductos e túbulos, e o volume nuclear das células dos ácinos, túbulos e ductos.
