Eight samples of accessory sex glands donkey were used to compare between the immature and mature donkey. The morphological parameters involved position, relation, shape, length, width, weight each gland. results in ampulla ductus deferens spindle shape strcture ends part deferens, located dorsaly urinary bladder opened into ejaculatory duct, measured 1.85±0.04cm, 3.81±0.18mm 0.96±0.02g 7.57±0....

In the rat, mouse and hamster, but not in the guinea-pig, Cowper's secretion reacts in vitro with vesicular secretion to produce a coagulant (Hart & Greenstein, 1968). Unlike vesiculase, the pH optimum of this reaction is acidic. In the rat, the active agent secreted by Cowper's glands that is responsible for coagulation is heat stable and non-dialysable. Electrophoretically the active molecule...

The initial step in the conversion of arachidonic acid to prostaglandins and related derivatives is catalyzed by the microsomal enzyme, cyclooxygenase. The ovine enzyme (from sheep vesicular glands) requires heme which is tightly bound as a prosthetic group (l-3). The bovine enzyme also requires heme (4) from which it is readily dissociated (5). In addition to free hematin, a variety of hemepro...

Examined with the electron microscope, the secretory cells of the submucosal glands of Brunner in the mouse present a curious combination of the fine-structural features of both serous and mucus-secreting cells. The cells have numerous mitochondria, abundant basal ergastoplasm, dense secretory granules that bear a superficial resemblance to pancreatic zymogen granules, and an unusually extensiv...

Head and neck cancer patients treated with irradiation often present irreversible salivary gland hypofunction for which no conventional treatment exists. We recently showed that recombinant neurturin, a neurotrophic factor, improves epithelial regeneration of mouse salivary glands in ex vivo culture after irradiation by reducing apoptosis of parasympathetic neurons. Parasympathetic innervation ...
