| Popis: | Many peritoneal dialysis (PD) patients with chronic renal failure (CRF) suffer from metabolic and nutritional abnormalities. However, these abnormalities have been not sufficiently investigated. At present, the resolution of these issues in this field has been hindered by the lack of suitable PD models. We attempt to develop a rat model of PD under no constraints and under non-anesthetization to evaluate amino acid solution as suitable nutritional therapy for renal failure. In our model, bilateral nephrectomy rats were dialyzed 6 h per day for three days. The dialysate was infused and removed continually via a metering pump. Under fasting, rats were infused with 5% glucose or amino acid solution for renal failure, and they remained alive. This model can be used to examine bilateral nephrectomy in rats for three or more days. We were also able to determine protein and calorie malnutrition, negative nitrogen balance, abnormalities in the plasma amino acid pattern, and calcium and phosphorus metabolism. Thus, this model has the characteristics of renal failure in humans and may be used to easily examine the metabolic changes due to loss of kidney function. |
