Aims: The interplay between natriuretic dopamine and antinatriuretic angiotensin II represents an important mechanism for the regulation of renal sodium and water excretion. Monoamine oxidase is the main metabolizing pathway for dopamine in the renal

In skeletal muscles, electrical shocks may elicit acute loss of force, possibly related to increased plasma membrane permeability, induced by electroporation (EP). We explore the role of the Na(+),K(+) pumps in force recovery after EP.Isolated rat so

Circulating lymphocyte numbers decrease following intense physical activity, possibly due to exercise-induced apoptosis. Increased reactive oxygen species (ROS) and glucocorticoids (GC) following exercise contribute to lymphocyte apoptosis. Intestina

Aim and methods: We investigated the immunohistochemical alterations of S100β-, S100-, glial fibrillary acidic protein (GFAP)- and isolectin B4-positive cells in the hippocampus after 5 min of transient cerebral ischaemia in gerbils. We also examine

Aims: Acetylcholine (ACh) is known to reduce the contractility of the heart by acting on myocardial muscarinic M2 receptors. ACh induces also an endothelial-dependent vasodilatation by causing the release of nitric oxide (NO), prostacyclin and endoth

Autoregulation of renal blood flow is an established physiological phenomenon, however the signalling mechanisms involved remain elusive. Autoregulatory adjustments in preglomerular resistance involve myogenic and tubuloglomerular feedback (TGF) infl

Renal vascular resistance is increased in essential hypertension, as in genetic models of hypertension. Here we review the evidence that this is at least in part due to structural changes in the afferent arterioles. Rat studies show that the renal af

Aim: Hepatic xenotransplantation from guinea-pig to rat has not been established. This failure is partly ascribed to differences in hepatic vascular characteristics between two species. However, the differences in hepatic vascular resistance distribu

The hydrodynamic properties of the urinary bladder in rat were examined by means of very small periodic changes in volume at different frequencies. The elastance increased with increasing frequency of volume changes, indicating the presence of viscoe

Skeletal muscle Na + /H + exchange was studied using giant sarcolemmal vesicles obtained from rat hind limb muscle. Experiments with either the 22 Na tracer technique or with the Na + sensitive fluorescent probe SBFI were conducted to determine the a
