Resumo: | There are report two human envenenomations for species from Clelia Fitzinger, 1826 (opisthoglyph snake). The patients exhibited symptoms similar from bothropic accident. Then this work have with objective, the hystological and histochemical study of Duvernoy's gland from Clelia plumbea. For the hystological observation of the Duvernoy's gland were using, with paraffin's cutting edge, two methods: Hematoxylin + Eosin and Toluidine's Blue. With historesine's cutting edge were using three methods: Metilen's Blue, Toluidine's Blue + Floxine and Toluidine's Blue. For the histochemical detection were using six techniques, with paraffin's cutting edge: PAS, PAS + Alcian Blue pH 2,5, Alcian Blue pH 2,5, PAS + Salivar Amilase, Method of Lars Grimelius and Method of Lillie. It was evidenced the predominance of serous cells on Duvernoy's gland. In relation to the histochemical constituion of the duvernoy's gland, was verified the presence of glucoconjugates neuters, enzymes and cells with reduetive activity. By fact from this species to kill his preys by constriction, the predominance of serous cells in the duvernoy's gland, don' t must be direct related with the subjugation of his preys, but with the digestive processes. Histological and histochemical analysis showed cells of Duvernoy's gland are constituted for two populations: serous cells (prodution of enzymes) and mucous cells (prodution of glucoconjugates).
