“…The cytoplasm of the cells were finely granular and faintly eosinophilic cytoplasm, but the apical border it became slightly basophilic in nature in the present study. This also the similar observation of Gaddi goats (Archana et al, 2009) stated that the late pre-pubertal Gaddi goats contained eosinophilic cytoplasm which stained relatively more darkly in the apical region. Type B cells were located in the basal lamina in between the type A cells having round or oval nucleus with indistinct cell boundaries.…”

SUMMARY:The present observation was aimed to evaluate the gross and histometric parameters of the vesicular glands of indigenous bulls. Twenty-eight bulls of three age groups were selected from the local market: the pre pubertal group A (<1 year n=4), pubertal group B (1.5-2.5 years, n=16) and post pubertal or adult group C (above 3 years, n=8). The weight, length (anterio-posterior), width (latero-medial) and the thickness (dorso-ventral) of the both left and right vesicular glands were recorded separately after slaughter of each animal. The left and right vesicular gland shows significantly different (p<0.01), in weight and length in every group. Left vesicular glands were slightly higher than the right in all parameters. The lobules of the gland showed folded mucosa, lined with pseudostratified columnar epithelium. Three types of cells were identified in the epithelium containing A, B and C cell. Type A cells were tall columnar cells having distinct cell boundaries with the oval, round or elongated nucleus. Type B cells were located in the basal lamina having round or oval nucleus with indistinct cell boundaries. Type C cells were narrow columnar cells interspersed between A cells with darkly stained cytoplasm. Lamina propria consisted of loose connective tissue surrounded the alveoli, tubules and some solid end pieces. The numbers of secretory end pieces were variable. The diameters of luminated or non-luminated acini of the glandular end pieces and ducts were increased gradually and significantly (p<0.01) with the advancement of age. The epithelial height of the duct and alveoli were increased with the advancement of age, but no significantly differences among them. Tunica adventitia and muscularis grew with the advancement of age while the interstitial tissue shrunk equally. Above all parameters help to conclude that the vesicular glands of the pubertal indigenous bulls were more functional.

“…These cells extend from basement membrane to the luminal surface of the gland [18]. Moreover, the secretory end pieces of the seminal glands in Gaddi goat exhibited apocrine mode of secretion [9]. The cytoplasm of the secretory epithelium is vacuolated in sections prepared by ordinary methods.…”

“…The secretory units are collected together in groups, each being surrounded by thin bundles of smooth muscle fibers which are intermingled with fibro architectural design comprised of circularly arranged collagenous bundles with reticular fiber [9,10,16]. In Gaddi goat, with the advancement of age, the number and size of secretory end pieces per unit area increased and the-inter glandular connective tissue stroma decrease [9].…”

The current investigation was carried out on the seminal glands of six apparently healthy mature male Buffalo bulls and six immature. The specimens were collected and examined anatomically and histologically after being fixed in 10% buffered neutral formalin. The specimens were subjected to processing till paraffin sections were obtained and stained. The anatomical and histological findings of the seminal glands are varying with age. Anatomically, the immature seminal gland was small sized, flaccid in texture, white in color and measured about 0.80-0.95 gm in weight, 1.95-2.50 cm in length, 1.00-1.15 cm in width and about 0.46-0.60 cm in thickness. Meanwhile, in mature one became larger in size, firm in texture, pale yellow in color, multi-lobulated where had a very large lobules on its outer surface giving, cluster of grapes liked appearance. It measured about 7-8 gm in weight, 5-6 cm in length, 2-2.5 cm in width and about 80-1.3 cm in thickness. Microscopically, the seminal gland was observed consisting of a stroma of connective tissue and a parenchyma of differentiating and undifferentiating acini in immature animal. Meanwhile, in mature one, the parenchyma was consisted of secretory end pieces and well-developed duct system. With advancement of age, the thickness of the capsule and trabeculae increased, also the number of secretory end pieces per unite area increased and the amount of inter-glandular connective tissue stroma reduced.

Fifteen adult Soay rams were used in this experiment. Eight animals were given subcutaneous implants containing melatonin, while the other seven animals were used as control. After 11 weeks, the rams were killed and the seminal vesicles were examined by light and electron microscope. In contrast to the control grouped animals, the melatonin treated rams showed morphological, morphometrical, and ultrastructural changes as a result of reactivation of the glandular tissues of the seminal glands. The ratio of interstitial connective tissues to glandular tissues was reduced in the treated group. Melatonin induced an evident significant increase in number and height of principal cells that showed signs of increased secretory activity; apical cytoplasmic protrusions became well developed and covering the inner surface of the glandular end-pieces, also, the basal cells were significantly increased in number. The main cytological alteration in the principal cells of the seminal vesicles in treated animals was prominent increase in the concentrically arranged membranes of sER, secretory vacuoles and glycogen granules and appearance of numerous lysosomes and multivesicular bodies. Interstitial Cajal- like cells were significantly increased in number and formed a network around the epithelium and between smooth muscle cells in the treated group. The main components of these cells were mitochondria, rER, sER, and many caveolae. The cytological alterations were accompanied by subepithelial and intraepithelial nonmyelinated nerve terminals in the treated animals. The results support the view that melatonin activates and increases the secretory activity of seminal gland in sheep.
