tenderness. The serum amylase was 4,500 Somogyi units and the blood urea was 36 mg/100 ml. She was treated with intravenous fluids and antibiotics. Three days after admission her urine output began to fall. Her serum calcium fell to 7-6 mg/100 ml. After 10 days her blood urea was 346 mg/100 ml, and intermittent haemodialysis was begun. Laparotomy next day confirmed the diagnosis of pancreatitis...

background: hemodialysis is a process of removing waste and excess fluid from blood when kidneys cannot function efficiently. it often involves diverting blood to the filter of the dialysis machin to be cleared of toxic substances. fouling of pores in dialysis membrane caused by adhesion of plasma protein and other toxins will reduce the efficacy of the filtre. objective: in this study, the inf...

Case report A 47-year-old woman was admitted to the Royal Sussex County Hospital on 11 June 1968 in renal failure due to chronic pyelonephritis. Investigations. Hb 52%4, WBC 7200/m3, blood urea 346 mg/100 ml, creatinine clearance 4-2 ml/min, serum sodium 140 mEq/l, calcium 8-0 mg/100 ml, phosphate 12-2 mg/100 ml, alkaline phosphatase 16-0 KA Units; urinary sodium 26 mEq/l, potassium 22-3 mEq/l,...

We used a perfused gill preparation from dogfish to investigate the origin of low branchial permeability to urea. Urea permeability (14C-urea) was measured simultaneously with diffusional water permeability (3H2O). Permeability coefficients for urea and ammonia in the perfused preparation were almost identical to in vivo values. The permeability coefficient of urea was 0.032 x 10(-6) cm/sec and...
