Some histochemical studies on the prostate, urethral and bulbourethral glands of the one-humped camel (Camelus dromedarius)

Abstract

The histochemical localization of carbohydrates, ribonucleoproteins (RNA), lipids, some hydrolytic enzymes, succinate and lactate dehydrogenase and acetylcholinesterase were investigated in the prostate, urethral and bulbourethral glands of the camel. These glands probably secrete carbohydrate-protein complexes. In the bulbourethral glands, they are sulphated mucopolysaccharides. RNA was seen in the cytoplasm of the prostate and urethral glands. Neutral lipids were cytoplasmic and present in moderate amounts in the prostate and urethral glands and in traces, in the bulbourethral gland. Acid phosphatase-containing granules were abundant in the prostate, moderate in the urethral glands and in traces in the bulbourethral glands. Alkaline phosphatase was observed in the apical cytoplasm of the prostate and bulbourethral glands and in the ducts of the urethral glands. ATPase and adenosine 5-monophosphatase were seen in the basal laminae and interstitial tissue. In the urethral glands, adenosine 5-monophosphatase was distributed diffusely in the cytoplasm. Succinate dehydrogenase was seen in the urethral and bulbourethral glands. Varying degrees of lactate dehydrogenase activity was observed in all the glands. Acetylcholinesterase was confined to neural elements. The pars disseminata and the urethral glands were considered as two distinct glandular zones along the pelvic urethra. The significance of these histochemical results is discussed.

Seminal Plasma Components in Camelids and Comparisons with Other Species

“…The source of the viscosity of camelid seminal plasma has not been documented, although it has been postulated that it is caused by glycosaminoglycans (GAGs) (Perk 1962; Ali et al. 1976).…”

“…lated that it is caused by glycosaminoglycans (GAGs) (Perk 1962;Ali et al 1976). The concentration of GAGs in alpaca seminal plasma is 15 times higher than in that of the ram (Kershaw-Young et al 2012) and almost three times higher than in human seminal plasma (Binette et al 1996 (Pattinson et al 1990;Mendeluk et al 2000), a-amylase (Mendeluk et al 2000), and chymotrypsin, subtilisin and papain (Pattinson et al 1990) all reduce viscosity.…”

Histomorphological Studies on the Prostate Gland of Donkey Equus Asinus during Different Seasons

“…In dogs, the lining epithelium was simple, stratified, or pseudostratified [5,22]. Frequently, flattened, large rounded, ovoid, wedged, or pyramidal-shaped cells were recorded between the lining cells of the secretory units of the prostate of dogs [22], shrew [23], camels [24], men [10], and buffalo bulls [17]. These basal cells possessed darkly stained cytoplasm and rounded nuclei with dense chromatin [18] in marmoset.…”

Morphology and Histochemistry of the Ferret Prostate

“…Earlier works on gross anatomy and histology of the prostate can be found in publications by Eckstein and Zuckenmm [1956] and Price and Williams-Ashman [1961]. Various aspects of morphology and seasonal activity of the pros tatic secretion have been studied in rodents [Schneider and Beck, 1953;Biswas and Deb, 1968;Hrabe, 1970;Ichihara, 1976], in the guinea pig [Oritz et al, 1956], opposunt [Chase, 1939;Marian and Allen, 1965], armadillo [Weaker, 1978], camel [Ali et al, 1976] and wombat [Barbour, 1981].…”
