Title in Portuguese
Morfologia do trato reprodutor masculino de capivara: estudo das glândulas anexas à uretra
Keywords in Portuguese
Capivaras
Microscopia
Morfologia (anatomia)
Órgãos genitais do macho animal
Roedores
Abstract in Portuguese
Para a realização dos estudos macro e microscópico das glândulas anexas à uretra, foram utilizadas doze capivaras (Hydrochaeris hydrochaeris) machos e adultos. Dez animais para estudo macroscópico e dois para o estudo histológico, dos quais foram coletados fragmentos das glândulas acessórias, imersos em solução fixadora de Bouin, lavados, cuidadosamente, em alcool de 70° ao absoluto. A seguir, foram submetidos aos processos histológicos de rotina e corados pelos métodos de Hematoxilina/Eosina e Tricrômico de Masson. Os resultados morfológicos encontrados foram: o ducto deferente possui um espessamento da parede, onde a luz permanece inalterada e sem presença de epitélio granular, abrindo na uretra, ao nível do colículo seminal. A glândula vesicular é par, tubular e seu ducto forma, na uretra o óstio ejaculador com o ducto deferente (colículo seminal) e possui um epitélio secretor do tipo pseudo-estratificado cilíndrico. A prostática é uma estrutura par, dividida em vários lobos (glândula tubular multilobada), com formato variável, e seus ductos abrem-se mediante duas pregas adjacentes ao óstio ejaculatório na uretra; e sua mucosa possui pregueamentos altos e ramificados, revestidos por epitélio pseudo-estratificado cilíndrico.

Abstract in English
For the realization of the macro and microscopical studies on the glands annexed to the urethra, twelve capybara (Hydrochaeris hydrochaeris) were used, males and adults. Ten animals for the macroscopical study, and two for the hystological study, from which fragments of the annexed glands were collected, imersed in Bowin fixing solution, carefully washed in absolute 70° alcohol. Afterwards, they underwent the routine histological processes and died by the Hematoxilin/Eosin and Masson's Tricomic methods. The morphological resuts found were: the deferent duct has a wall thickening, where light remains unchanged and whithout presence of granular epithelium, opening in the urethra at the seminal coliculum . The vesicular gland is in pair, tubular and its duct forms, in the uretra, the ejaculatory ostium with the deferent duct (seminal coliculum) and has a secretory epithelium of the pseudostratified cilindrical kind. The prostate is in pair, divided into several lobus (multilobated tubular gland), with varying shape and its ducts open at two folds adjacent to the ejaculatory ostium in the urethra and its mucosa has high and ramified folds, lined with pseudostratified cilindrical epithelium.
