646MORPHO-HISTOMETRIC EVALUATIONS OF PRE-PUBERTAL, PUBERTAL AND POST PUBERTAL PROSTATE GLANDS OF INDIGENOUS BULLS (Bos indicus) of BANGLADESHThe present study was aimed to evaluate the morpho-histometric parameters of prostate gland of indigenous bulls. Twenty eight bulls of three age groups were selected from the local market: the pre pubertal group (˂1year n=4), pubertal group ((1.5- 2.5years, n=16) and post pubertal group or adult (˃3 years, n=8).The prostate glands of bull consisted of corpus prostate and pars disseminata portion were distinguished. In all three groups of bull showed the corpus prostate was a band form. The both portions enclosed by the connective tissue capsule composed of mainly collagen and smooth muscle cells. Interlobular connective tissue decreased significantly (p˂0.01) with the advancement of age. The secretory ends pieces were lined by simple cuboidal epithelium, simple low columnar epithelium and simple high columnar epithelium in prepubertal, pubertal and adult bulls respectively. The height of the lining epithelium increased with the advancement of age significantly (p˂0.01). In ducts, height and number of the typical enfolding were increased with age. The ducts were lined by simple columnar or pseudostratified epithelium. The average diameters of the ducts and the height of the lining epithelium increased significantly (p˂0.01) with the advancement of age. The findings revealed that the morpho-histometric changes were associated with the advancement of ageadhikarygn.dah@sau.ac.bdResearch682015Prostate gland,Histometry,Puberty, Indigenous bullGitaindro Nath Adhikary,MST.
