Chronic renal injury can be mediated by angiotensin II (ANG II) and prostanoids through hemodynamic and inflammatory mechanisms and attenuated by individual suppression of these mediators. In rats with (5/6) renal ablation (Nx), we investigated 1) the intrarenal distribution of COX-2, ANG II, and the AT(1) receptor (AT(1)R); 2) the renoprotective and(More)
Intravenous ganciclovir is the standard treatment for cytomegalovirus disease in solid organ transplant recipients. Oral valganciclovir is a more convenient alternative. In a randomized, international trial, recipients with cytomegalovirus disease were treated with either 900 mg oral valganciclovir or 5 mg/kg i.v. ganciclovir twice daily for 21 days,(More)
Locally generated angiotensin II (AngII) may be involved in the pathogenic mechanisms of chronic renal diseases. Renal expression of AngII and other components of the renin-angiotensin system (RAS) were analyzed by immunohistochemistry and Western blot in a model of chronic progressive nephropathy induced by inhibition of nitric oxide synthesis. Renal(More)
Transplantation of pancreatic islets is a promising therapeutic treatment for type 1 diabetes mellitus. For clinical and experimental transplantation, a large number of pure pancreatic islets are required for transplantation. Thus, the improvement of islet isolation and purification techniques are crucial. In this context, iodixanol-based solution,(More)
We measured plasma concentrations of soluble receptors for IL-2 (sIL-2R) and tumour necrosis factor-alpha (TNF-alpha) in 149 haemophilia patients. Soluble IL-2R levels were elevated in 37% of 62 HIV-seronegative patients (mean 570 +/- 27 U/ml versus 361 +/- 17 U/ml in the control group, P less than 0.0001), in 78% of 68 HIV-seropositive patients (928 +/- 49(More)
BACKGROUND It has been speculated that increased levels of circulating or intraperitoneal pro-inflammatory cytokines such as interleukin 6, and pro-angiogenic vascular endothelial growth factor (VEGF) may contribute to high peritoneal small-solute transport rate (PSTR) in continuous ambulatory peritoneal dialysis (CAPD) patients. In this study we evaluated(More)
BACKGROUND Experimental and clinical evidence suggests that inflammation plays a role in the pathogenesis of diabetic nephropathy, in addition to, or in concert with, the associated hemodynamic and metabolic changes. The present study assessed the effects of chronic anti-inflammatory therapy in experimental diabetic nephropathy. METHODS Adult male(More)
Humoral and cellular immune mechanisms are thought to be involved in various forms of vasculitis and glomerulonephritis. Recent clinical and experimental results point to a role of cytokines in ANCA-positive vasculitides. We analyzed tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta) and interleukin-2 receptors (IL-2R) in renal biopsies(More)
BACKGROUND Mycophenolate mofetil (MMF), an inhibitor of lymphocyte proliferation, has been used to prevent allograft rejection. We investigated whether MMF also limits progressive renal injury in rats with 5/6 renal ablation, a model not primarily related to immunologic mechanisms. METHODS Eighty-eight adult male Munich-Wistar rats underwent ablation and(More)
