To clarify the natural course of gold nephropathy and thereby facilitate its clinical management 21 patients with rheumatoid arhritis who developed proteinuria during treatment with intramuscular sodium aurothiomalate were studied in detail throughout their renal illnesses. Renal biopsies were performed, and creatinine clearance and protein were measured serially for 60 months (range 16-130 months). Ten patients developed proteinuria after six months' treatment, 15 after 12 months, and 18 after 24 months. When treatment wa stopped the proteinuri reached a median peak of 2-1 g/day (range 0 7-30*7 g/day) at two months (range 1-13 months) before resolving spontaneously, in eight patients by six months, in 13 by 12 months, and in 18 by 24 months. All patients were free ofproteinuria by 39 months, the median duration being 11 months. The median first and last measurements of creatinine clearance showed no significant change (77 mI/minute and 59 mI/minute, respectively), and no patient died from or needed treatment for renal failure. HIA-B8 or DR3 alloantigens, or both, were identified in seven patients. Renal biopsy specimens showed membranous glomerulonephritis in 15 patients, a minimal change nephropathy in two, mesangial electron dense deposits in two, and no appreciable glomerular changes in two.In these 21 patients the proteinuria of gold nephropathy

Renal Insufficiency (RI) is a common finding in patients suffering from end-stage liver disease. The causes of RI are reported to be multifactorial and the degree of RI can range from early functional impairment to hepatorenal syndrome (HRS). The process of liver transplantation is highly likely to exacerbate the symptoms and sequelae of renal dysfunction. RI continues to be a cause of morbidity and mortality in the intraoperative and postoperative periods. With careful evaluation and monitoring in addition to appropriate intervention, a uniformly good outcome may be possible even for these most complicated patients. This paper will describe successful perfusion interventions carried out during the three phases of liver transplantation: pre-anhepatic, anhepatic and reperfusion at our institution for a three-year period. Intraoperative plasmapheresis (n = 3), continuous veno-venous hemofiltration (CVVH) (n = 7), intraoperative dialysis (n = 8), and intraoperative dialysis with fluid removal (n = 3) techniques will be presented for review.

A new type of high-temperature conditional cell division mutant has been isolated in Agmenellum quadruplicatum strain BG1 in which the process of cell division is uncoupled from that of growth at 39 C. This mutant produces abnormally small cells under conditions of nutrient limitation and forms multinucleoid filaments under normal growth conditions.
