Efeito da lactulose sobre os teores séricos de ureia, creatinina, cálcio e fósforo em cães não azotêmicos / Effect of lactulose on serum urea, creatinine, calcium and phosphorus in non-azothemic dogs

The present study evaluated serum levels of urea, creatinine, calcium and phosphorus in non-azothemic dogs by continued use of lactulose orally. Serum levels of urea, creatinine, calcium and phosphorus were determined in Beagle dogs, clinically healthy and without biochemical changes (non-azothemic), undergoing oral treatment with lactulose (n = 6), for a period of 30 days. The prebiotic showed no significant lowering effect on serum urea and creatinine, but the values of calcium and phosphorus, as well as their relation, were modified with reduced serum phosphorus levels in animals treated with lactulose compared to controls, with a significant difference...
