Nine patients with renal cell carcinoma and severe hematuria were palliatively treated with a new type of angioocclusion: The concept of capillary embolization. The so-called occlusion gel Ethibloc was used as embolizing agent. Each patient was followed up until death or for at least 4 years. All patients had a stage T3 or T4 tumor, 3 patients had(More)
Sulfated proteoglycans (fixed anionic sites) on the glomerular basement membrane (GBM) of kidneys from diabetic and nondiabetic patients have been demonstrated by electron microscopy using polycationic dyes (ruthenium red, polyethyleneimine). These substances were used for immersion fixation of renal biopsy specimens. The thickened GBM of diabetics revealed(More)
Collateral vessels in tumors and arteriovenous malformations limit the effectiveness of therapeutic embolization. Capillary propagation of embolization media represents a possible solution of the problem. Embolization with Ethibloc (Hamburg-Norderstedt), a vegetable protein dissolved in alcohol, was performed in 15 renal arteries of dogs. Three embolized(More)
BACKGROUND Chronic transplant nephropathy remains a poorly defined inflammatory process that limits the survival rate of most renal transplants. We analyzed the gene profile of chronically rejected kidney transplants to identify candidate genes that characterize chronic transplant nephropathy. METHODS To distinguish genes present in normal renal tissue or(More)
BACKGROUND Doxorubicin induces a self-perpetuating nephropathy characterized by early glomerular and late-onset tubular lesions in rats. We investigated the potential role of mitochondrial injury in the onset of these lesions. METHODS Rats were treated with intravenous doxorubicin (1 mg kg(-1) week(-1)) for 7 weeks and were sacrificed either 1 week(More)
The changes in cell population kinetics in response to a mechanical stimulation by wounding were studied in a hyperplastic epidermis, papilloma and a squamous cell carcinoma of the mouse dorsal skin induced by repeated treatments with 20-methylcholanthrene. The G0 cell population, which consists of about 66% of the basal cells in the dorsal epidermis of the(More)
A 14 year old boy was admitted for vomiting, anorexia, flank pain and leukocyturia/hematuria. Shortly after admission, he developed anuria and acute renal failure so that hemodialysis had to be started. Pre- and post-renal causes were excluded. There were no signs of acute glomerulonephritis; liver enzymes were normal. The 123Iodine-Hippuran scan showed a(More)
The prognosis of Fabry disease has changed since enzyme-replacement treatment was introduced. Therefore, early diagnosis is instrumental. We describe a family presenting with chronic renal failure and proteinuria in which classic skin and neurological features were absent and the diagnosis of Fabry disease was difficult and not established until a second(More)
The influence of charge and size on antigen binding to the rat glomerular basement membrane (GBM) was investigated. Chemically cationized ovalbumin, human serum albumin (HSA), human immunoglobulin G (Hu IgG), horse spleen ferritin and human immunoglobulin M (Hu IgM) were injected into rats intravenously. By immunofluorescence significant glomerular binding(More)
Medullary cystic kidney disease (MCD) is characterized by multiple renal cysts at the corticomedullary boundary area, by autosomal dominant inheritance, and by onset of chronic renal failure in the third decade of life. We report on a family with three affected individuals of both sexes in two generations presenting with end-stage renal failure at age 22-31(More)
