Análise histológica das glândulas uretrais da capivara (Hydrochoerus hydrochaeris) / Histological analysis of urethral glands of the capybara (Hydrochoerus hydrochaeris)

Para realização do estudo microscópico das glândulas anexas à uretra masculina, foram utilizadas duas capivaras (Hydrochoerus hydrocaeris), adultas, das quais foram coletados fragmentos das glândulas genitais acessórias, imersos em solução fixadora de Bouin e lavados cuidadosamente em álcool de 70 por cento 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. A glândula vesicular possui um epitélio secretor do tipo pseudoestratificado colunar. A glândula prostática possui mucosa com pregueamentos altos e ramificados, revestido por epitélio pseudoestratificado cilíndrico. Machos de capivaras possuem glândulas vesiculares e próstata como glândulas uretrais. No material examinado não foi identificado epitélio secretor correspondente a glândula bulbouretral e morfologicamente assemelha-se aos outros histricomorfos.

To perform a microscopic study of the glands attached to the male urethra, we used two adult capybaras (Hydrochoerus hydrocaeris) from which fragments of the urethral glands were collected, immersed in Bouin's fixative solution, washed thoroughly with 70 percent to absolute alcohol, submitted to routine histological techniques and stained with hematoxylin/eosin and Masson's trichromic method. The morphological findings were: Vas deferens has a thickening of the wall without granular epithelium and with unchanged lumen; the vesicular gland has a secretory epithelium of pseudostratified columnar type; the prostate gland has a high and ramified mucous membrane covered with pseudostratified cylindrical epithelium. Male capybaras have vesicular, prostate as urethral glands. In the material examined, no secretory epithelium corresponding to bulbourethral glands was identified; morphologically it resembles to the other histricomorphs.

Secretory alterations of urethral glands in complete Freund's adjuvant-induced prostatitis in rats / 第三军医大学学报

Objective To investigate the effects of prostatitis on secretory alterations of urethral glands in rats.Methods Twenty adult Sprague-Dawley rats were randomly divided into prostatitis group and control group.The prostatitis group(n=10) was injected with 0.1 ml Freund's complete adjuvant at each lateral lobe while the control group(n=10) with 0.1 ml 0.9% physiological saline.Two weeks later the rats were killed and the urethral glands were harvested for pathologic examination and immunohistochemical staining.Results ① There was a great quantity of lymphcells and mononuclear cells infiltrating the prostate gland in prostatitis group while there was no inflammatory cells in control group.② AB-PAS pathologic examination results in urethral glands showed that the grume area,diameter,optical density in control group were significantly less than those of the prostatitis group(P
