Gross Anatomical, Histological and Histochemical Studies on the Postnatal Development of the Prostate Gland of Gaddi Goat

Abstract

SUMMARY:The study was conducted on the prostate gland of Gaddi goat from one day old to more than five years of age divided into three groups viz; Prepubertal (1 day old to < 18 months of age), Pubertal (18 months to < 5 yrs of age) and Postpubertal (> 5 yrs of age). The prostate comprised of corpus prostatae, a band like structure close to the junction of vesicular gland with the urethra, and the pars disseminate which extended in urethra well from its origin to the point of duct of bulbourethral gland. Microscopically, the corpus prostatae comprised of two compact glandular masses lying one over the other, dorsally over the origin of pelvic urethra covered by a thick fibro-reticular capsule. The gland composed of end pieces (luminated and non-luminated acini) and ducts arranged in lobulated fashion. The thickness of inter and intralobular connective tissue decreased with increased age at the expense of the growth of paraenchyma. With age the luminated secretory end pieces increased, while the non-luminatedend pieces decreased in the lobules of the gland. Glandular parenchyma were rich in mucous components by 6 month age serous and mucous components became almost equal and at 12 month age majority of the secretory end pieces turned in to serous type. The excretory ducts which were lined by stratified cuboidal epithelium in one day old kids changed to transitional epithelium in late prepubertal and pubertal animals. The glandular elements were PAS and Best's carmine reactive while interstitial connective tissue was non reactive. Mild alkaline phosphatase reaction was evident in the interstitial connective tissue cells. A strong acid phosphatase reaction was evident in the endothelium. BPB reaction for protein was moderate to intense. Ducts and acini were PAS and Alcian Blue reactive. The reaction for glycogen and AMPS contents in the gland increased with age. It was very intense in the pubertal animals. Moderate DNA activity, mild to moderate alkaline and acid phosphatases in the glandular acini and ductal epithelium revealed functionally active secretory glands particularly in the pubertal animals.

Seasonal variations in enzyme histochemistry of accessory sex glands in buffalo bull

“…The strong activity of NSE was observed in glandular and ductular epithelium, whereas the smooth and skeletal muscles showed weak and moderate reaction, respectively (Fig 19) (Table 2). Similar findings have been reported in ram (Roy et al1985), goat (Pawar et al 1988), buffalo bull (Chopra, 1998) and Gaddi goat (Pathak et al 2012).…”

“…Fine granular activity of LDH was found in parenchyma and weak in the stroma (Fig 9), which may be related to its role in conversion of pyruvate to lactate as it is an enzyme of glycolysis. Moderate activity of G-6-PD was observed in parenchyma and weak in the stroma (Fig 6).The glandular and the ducts of bulbourethral were strongly positive for diaphorases (NADPHD and NADHD) whereas a weak activity for NSE (Table 3) was observed (Fig 15, 18 and 20).Similar findings have been reported in ram (Roy et al1985), goat (Pawar et al 1988), buffalo bull (Chopra, 1998), buck (Pyne et al 1991) and Gaddi goat (Pathak et al 2012).…”

Seasonal variations in histomorphology and histochemistry of the prostate gland of buffalo bulls

“…The luminal border and subapical cytoplasm gave strong positive reactions for neutral mucopolysaccharides, whereas the reaction was mild in the rest of the cytoplasm in the corpus prostate of camel [16]. The cytoplasm of all the secretory end pieces was strongly PAS-reactive in Gaddi goat [13], which was in accordance with the present study.…”

“…The Alcian blue reaction was strongly positive in certain lobules [18], as seen in summer in the present findings. In pubertal animals, the cytoplasm of all the secretory end pieces showed very strong Alcian blue reactions at the luminal border [13]. Similar to the current study, in buffalo bulls [3] and in bucks [18] researchers found mucoprotein and glycoprotein in the serous alveoli.…”

Postnatal Developmental Anatomy of Testes and Epididymis of Gaddi Goats

“…Fragmentary anatomical reports on the anatomy of testis of Malabari goats (Harshan et al, 1978), Assam goats (Baishya et al, 1985(Baishya et al, , 1986, Maradi (Red Sokoto) goats (Ogwuegbu et al, 1985;Nwoha, 1995), Beetal goats (Gupta, 1989), German Brown, Anglo Nubian goats and Caninde goats (Barnabe et al, 1992), Cashmere goats (Walkden-Brown et al, 1994) and Japanese Tokara goats (Nishimura et al, 2000) are available. The Gaddi goats which are the inhabitants of North Western Himalayas of India and lend a vital support to the livelihood of the local tribes have not been utilized for such study so far (Pathak et al, 2012). The present paper reports the basic anatomical data on the testes and epididymis of Gaddi goats at different ages and state of reproduction.…”
