[Effects of MRX-III on chronic renal failure in rats].
The effects of MRX-III, a new amino acid solution for renal failure, on survival, progression of renal insufficiency, metabolism of calcium and phosphorous, and nutritional status were studied in rats with chronic renal failure induced by 7/8 renal ablation. These rats were injected intraperitoneally with MRX-III, an essential amino acid solution for renal failure (Amiyu; Sol. A) or a general amino acid solution (Moripron-F; Sol. M) for 12 weeks under the condition of a 3.5% protein diet, and these effects were compared with those in control rats infused with Sol. M under a 22% protein diet.1) Infusion of MRX-III or the other solutions under a low protein diet prolonged survival time and improved the uremic status indicated by azotemia, polyuria, albuminuria, hypocalcemia and hypertension. 2) Increase in body weight and tissue weight of rats treated with MRX-III or Sol. A was better than those in rats treated with Sol. M. MRX-III as well as Sol. A showed a tendency to provide a better nutritional effect in comparison with Sol. M.
