histological features of interrenal and chromaffin cells in relation to seasonal testicular activities in notopterus notopterus (pallas, 1769)
نویسندگان
چکیده
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. the cytophysiological features of the interrenal, chromaffin cells and various spermatogonial cells were observed during different reproductive phases. in the present investigation, the relationships between the changes in the interrenal and chromaffin cells along with the spermatogenic cells at different periods of the breeding cycle were discussed.

The pituitary gland of Notopterus notopterus (Pallas, 1769) was situated in a shallow pit at the floor of the skull and attached to the infundibulum. On the basis of tinctorial properties the cell types of pituitary were indentified which were distributed in the rostral pars distalis (RPD) proximal pars distalis (PPD) and pars intermedia (PI) in different proportions. The three zones were inner...
متن کاملEffect of cortisol on testis of freshwater fish Notopterus notopterus (Pallas).
Cortisol (20, 40 and 60 micrograms/fish for 10 days) treatment caused an increase in testicular-somatic index (TSI) in immature N. notopterus whereas in mature fish no change from that of controls was observed. Histology of testis indicated that spermatogenetic activity was activated in immature fish while it was inhibited in mature fish. Testicular cholesterol exhibited a similar response. The...

The health of fish can be affected by environmental factors (stress), nutrition as well as by pathogens. Stress in fish may be induced by various abiotic environmental factors such as changes in water temperature, pH, oxygen concentration and water pollutants including pesticides, insecticides (Meier et al., 1983; Lebelo et al., 2001), petroleum products and heavy metals (Witeska, 1999). Biotic...

In teleosts, the basal part of the retinal pigment epithelium (RPE) is relatively smooth, i. e., it is free of basal membrane infoldings. In the featherback, Notopterus notopterus, whereas this is the situation in light adaptation, during dark-adaptation, especially when kept for prolonged periods (6-9 hour), numerous infoldings appear at the basal region, as found uniquely by transmission elec...

In the present study tissue cholesterol and serum cortisol changes during two reproductive phases have been correlated in the freshwater fish Notopterus notopterus. The reproductive cycle of N. notopterus has two phases such as breeding phase (April - August) and non breading phase (October - December). The cholesterol content of the ovary and liver increased during breeding phase. The serum co...
