Levine S, Saltzman A: Acute uremia produced in rats by nephrotoxic chemicals is alleviated by protein deficient diet. Ren Fail. 2003 Jul;25(4):517-23.
Rats injected with mercuric chloride develop an acute renal tubular necrosis with uremia, which is frequently lethal. Pretreatment for 3 or 7 days with a protein-free diet reduces the mortality, the clinical signs (tremor), and the severity of renal tubular necrosis, and ameliorates the uremic chemical findings in the serum. Similar results followed injection of a nephrotoxic amino acid, D-serine, after pretreatment with a protein-free diet. Indirect evidence suggests that induction of metallothionein may be involved, at least in the experiments with mercury. Acute uremia produced by nephrotoxic chemicals may be useful for further studies of the role of nutrition in uremia, while avoiding the surgical procedures and prolonged observations required for the "remnant kidney" models. |
