Abstract

The present investigation was done to clarify the histological and histochemical characteristics of the well-developed prostate gland in the adult local dogs (Canis familiaris). The tissue specimens were taken from the prostate gland, the samples were processed by routine histological techniques and stained. Histologically, the body of the prostate in resting was characterized by abundant amounts of fibrous tissue with little glandular lobes that were surrounded by a very thick fibromuscular capsule. Each lobe was composed of numerous variable size lobules that contained several alveoli lined by simple cuboidal cells. While in stimulating status, the gland is characterized by much amount of glandular tissue, thin fibro muscular capsule and thin interlobar connective tissue. The disseminated part of the prostate gland was composed of little scattered small size glandular lobules within the subepithelial cavernous tissue of the urethra about (1-2) cm post body of prostate. Histochemical, the stimulating prostate showed marked intense magenta colour which referred to the presence of both acidic and neutral glycoprotein secretory products when stained with Combine Alcian blue (2.5 pH) + PAS stain. In conclusion, this study showed the differences between the prostate glands in the resting and stimulating status in local breed dogs.
