[Structural-metabolic features of uremic gastroenteropathy].
Concentrations of uremic toxins in the blood and jejunal juice of 72 patients with chronic renal failure (CRF) were studied as well as morphologic changes in biopsies from jejunal mucosa and submucosa, activity and location of acid and alkaline phosphatase as markers of intracellular and transmembrane transport. It was found that maximal excretion of uremic toxins in the jejunum occurs in CRF stage IIA and IIB. In terminal CRF excretion of uremic toxins delays from their concentration in the blood. This process is related with changes in enzymic processes. Histologically, all the examinees exhibited signs of chronic enteritis.
