BACKGROUND Ultrafiltration (UF) is assumed to enhance urea removal during haemodialysis (HD) because of convective transport and because of contraction of urea distribution volume. However, UF-induced blood volume reduction has been hypothesized to enhance peripheral urea sequestration and post-dialysis urea rebound (PDUR), possibly reducing HD effectiveness. The effect of UF on PDUR was invest...

Investigations using ammonium citrate-(15)N and urea-(15)N showed that children in the acute stage of kwashiorkor and marasmus receiving a diet of adequate protein content retained a considerable percentage of the label from both compounds. Excretion of both total (15)N and urea-(15)N was subnormal and elimination was virtually completed 36 hr after administration of the isotope. During recover...

The rate at which urea enters the body pool of urea in sheep was investigated using isotope dilution techniques. Both single injection and constant infusion of carbon-14 urea were used. Urea excretion rates were calculated by measuring the urea in urine collected from a catheter in the bladder. Urea entry and excretion rates were measured in sheep fed rations containing 3.5, 9, 17 and 27% crude...

Aim: Present study was aimed to analyze difference of hematological parameters and blood urea level between Recovered Dead cases COVID-19. Material & Methods: A hospital based undertaken wherein 65 were analyzed.

Or" the many biochemical tests done 011 the blood for clinical purposes, the estimation of blood urea is one of the most important. This is indicated in nephritis, uraemia, enlarged prostate, obstruction to the urinary flow, and various other conditions and throws considerable light on the condition of the patient. In normal healthy Bengalees it is rare to find a blood urea-nitroge11 value grea...
