A variety of lesions of the central nervous system may be associated with disturbances of renal function characterized by either the increased urinary loss of sodium and chloride (1-3) or the retention of salt (3-8). It has also been postulated that changes in the excretion of salt, secondary to alterations in the volume of blood or extracellular fluid, are mediated by a "volume receptor" locat...

introduction: the selection of   optimal treatment of obstructive nephrouropathy requires information about the functional status of each kidney. nuclear renal scanning objectively measure differential renal function, multiple studies have demonstrated the role of assessment of renal perfusion and gfr with triphasic ct. the aim of this study is to assess the role of ct based on renal parenchyma...

A model was developed to study post-transplant hypertension after allogeneic kidney transplantation between two inbred normotensive rat strains. Prolongation of graft survival was achieved by 'active immunological enhancement'. Renal function, systolic blood pressure and plasma renin concentration were determined. The systolic blood pressure started to rise in the second week after allogeneic t...

The tight regulation of the body's sodium and chloride concentrations is so important that multiple mechanisms work in concert to control them, and a minimal amount of salt is required for survival. Sodium (Na) and chloride (Cl) are the principal ions in the extracellular fluid, especially in blood plasma. Sodium retention is the most common renal abnormality of cirrhosis and eventually leads t...

nitric oxide (no) is implicated as an important mediator of, or intermediary in, inflammation, immunity and neurotransmission. in the kidney, no is involved in haemodynamic regulation, control of vascular tone and tubular function. formation of oxygen-derived free radicals (ofr) have been documented in renal ischaemia- reperfusion before. in this study , we investigated the significance of no f...

Rats with normal renal function (Experiment 1, n = 12) and uninephrectomized (1/2Nx) rats (Experiment 2, n = 12) were fed diets with normal P (NP) and either normal (NF) or high fat (HF). Rats with intact renal function (Experiment 3, n = 12) were also fed NF or HF diets with high P (HP). Additionally, uremic (5/6Nx) rats (n = 16) were fed HP diets with NF or HF. Feeding the HF diets resulted i...

a 14 years old girl, with documented ewing's sarcoma, was treated by both chemotherapy and surgery. an initial bone scan (tc-99m-mi)i*) did not reveal a renal lesion. however, following therapeutic irradiation, there was retention of the bone imaging agent in a portion of the kidney that had been included in the radiation field. this reflected the effects of radiation related parenchymal altera...

Obese subjects often have hypertension and related cardiovascular renal diseases. In obese impaired renal-pressure natriuresis causes sodium retention, leading to the development of salt sensitive hypertension. Obesity is due fluid retention high fat in cells, so cells will active any factors stimulate secretion aldosterone, there be sensitivity blood pressure only. But it not necessarily linke...

Decompensation in heart failure occurs when the heart fails to balance venous return with cardiac output, leading to fluid congestion and contributing to mortality. Decompensated heart failure can cause acute kidney injury (AKI), which further increases mortality. Heart failure activates signaling systems that are deleterious to kidneys such as renal sympathetic nerve activity (RSNA), renin-ang...
