High environmental hydrogen peroxide (H2O2) has been demonstrated to be toxic for fish. However, the response mechanism of fish chronic H2O2 exposure is not yet well understood. Therefore, this study aimed investigate alteration in ion transport gills and analyzed potential after exposure. The common carps were exposed 0, 0.25, 0.50, 1.00 mM 14 days. histopathological evaluation results indicat...
Cyprinus carpio is a stenohaline species but can tolerate some ranges of changes in environmental salinities, so histomorphological methods and Na+-K+ ATPase and Aquaporin 3 immunohistochemistry were performed on common carp kidney as an osmoregulatory organ in experimental groups and control in order to investigate their possible roles during salinity challenge. Five groups of fish (n=25) with...
The structure, ultrastructure and osmoregulatory function of the branchial chamber were investigated in Palaemon elegans (Rathke, 1837) by light microscope, electron microscope and immunohistochemistry methods, respectively. Each chamber possesses a branchiostegite, 3 epipodites and 8 phyllobranchiate gills. The lamellae are attached along the two outer surfaces of the triangular gill axis. Ult...

introduction: ouabaine is a well-known atrioventricular (av) node depressant agent, but its effects on functional properties of the av node have not been cleared. the aim of the present study was to determine how ouabaine administration modifies the rate-dependent properties of the av node. methods: selective stimulation protocols were used to quantify independently electrophysiological propert...
PURPOSE Earlier studies from this laboratory demonstrated the ability of lens epithelium to synthesize new Na,K-adenosine triphosphatase (Na,K-ATPase) catalytic subunit (alpha) polypeptide under conditions of increased ion permeability. In the present study, the authors considered whether continuous synthesis of Na,K-ATPase protein is necessary for maintenance of Na,K-ATPase activity in lens ce...
