[Increased kidney cell proliferation caused by folic acid treatment after dichromate induced renal failure (author's transl)].

Folic acid is given intravenously to rats 5 to 10 days after a dichromate induced damage of the kidneys. These injection cause an additional damage in the function and structure of the kidneys, but on the other hand, they induce a cell proliferation detected by the increased uptake of thymidine. This cell proliferation in the kidney-tissue seems to be a part of specific reactions to the folic acid.
