Germanium dioxide

Since 1982, there have been 18 reported cases of acute renal dysfunction or failure, including two deaths, linked to oral intake of germanium elixirs containing germanium dioxide (GeO2) or Ge-132. In these cases, biopsies show vacuolar degeneration in renal tubular epithelial cells, without proteinuria or hematuria, in the absence of glomerular changes. Get price
