histological features of interrenal and chromaffin cells in relation to seasonal testicular activities in notopterus notopterus (pallas, 1769)
the adrenal gland of notopterus notopterus (pallas) consisted of interrenal and chromaffin cells, distributed around the main branches of posterior cardinal vein in most anterior part of the pronephric kidney. seasonal histological characteristics of the interrenal and chromaffin cells in relation to testicular activity of n. notopterus were studied by adopting different staining techniques. th...
متن کاملDistributional pattern of different cells with special emphasis on the seasonal variations of gonadotrophs in the pituitary gland of Mystus vittatus (Bloch, 1794) in relation to testicular activities
Different cell types were identified in the pituitary gland of Mystus vittatus on the basis of their characteristic arrangement, distribution and tinctorial properties. The adenohypophysis was subdivided into three distinct zones innervated by the process of neurohypophysis. The acidophilic prolactin (PRL) cells and adrenocorticotropic cells were observed in the rostral pars distalis (RPD). The...

15 صفحه اولthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Histological Changes in the Activity of the Thyroid Follicles and Its Impact on Ovarian Tissues in Mystus Vittatus (bloch, 1794) during Growth, Maturation and Spawning Phases
The thyroid gland of Mystus vittatus was unencapsulated, composed of follicles scattered mainly around the ventral aorta in the sub pharyngeal region. Each follicle provided with agranular eosinophilic colloid materials in the central lumen was encircled by a single layer of epithelial cells. The follicular cells varied according to the secretary activity in harmony with the reproductive cycle....
