Urea transporters and sweat response to uremia
In humans, urea is excreted in sweat, largely through the eccrine sweat gland. The urea concentration in human sweat is elevated when compared to blood urea nitrogen. The sweat urea nitrogen (UN) of patients with end-stage kidney disease (ESRD) is increased when compared with healthy humans. The ability to produce sweat is maintained in the overwhelming majority of ESRD patients. A comprehensiv...
متن کاملMyocardial bioenergetic abnormalities in experimental uremia
PURPOSE Cardiac bioenergetics are known to be abnormal in experimental uremia as exemplified by a reduced phosphocreatine (PCr)/adenosine triphosphate (ATP) ratio. However, the progression of these bioenergetic changes during the development of uremia still requires further study and was therefore investigated at baseline, 4 weeks and 8 weeks after partial nephrectomy (PNx). METHODS A two-sta...
متن کاملReduced hepatic synthesis of calcidiol in uremia.
Calcidiol insufficiency is highly prevalent in chronic kidney disease (CKD), but the reasons for this are incompletely understood. CKD associates with a decrease in liver cytochrome P450 (CYP450) enzymes, and specific CYP450 isoforms mediate vitamin D(3) C-25-hydroxylation, which forms calcidiol. Abnormal levels of parathyroid hormone (PTH), which also modulates liver CYP450, could also contrib...
متن کاملStudies on the control of sodium excretion in experimental uremia.
A study of the mechanisms governing the high rate of sodium excretion per nephron characteristic of patients with chronic renal disease has been made in dogs. A "remnant kidney" was produced by 85% infarction of the left kidney while the right kidney was left intact. A bladder-splitting procedure allowed simultaneous measurement of glomerular filtration rate and the rate of sodium excretion by ...
متن کاملMyocardial interstitial fibrosis in experimental uremia--implications for cardiac compliance.
Experimental uremia is known to cause cardiac hypertrophy. In the present study we examined the effect of uremia with or without concomitant treatment of hypertension by the converting enzyme Ramipril (125 micrograms/day) on micromorphometric indices of cardiac interstitium at the light microscopical and ultrastructural level. In male SD rats, 21 days of uremia caused an increase of total heart...
