[Enterosorption in experimental acute kidney failure].
The paper provides the results of 32 experiments on 22 mongrel male dogs with a view to measuring creatinine levels in the lumen of various intestinal segments before and after bilateral nephrectomy and evaluating the effects the enterosorbent brand SKN administered into isolated portions of the intestinal tube on alteration of intraluminal concentrations of creatinine, serum creatinine, and "middle-sized" molecules. Four parts of the intestine were identified: (1) proximal; (2) middle and (3) distal portions of the small intestine, and (4) the large intestine up to the anal sphincter. Two days following bilateral nephrectomy, creatinine levels were increased in the proximal, middle, distal portions of the small bowel and in the large bowel by 18, 11, 5, and 1.4 times, respectively, as compared to the baseline creatinine concentration in the intestinal parts mentioned. The administration of the enterosorbent into the different intestinal parts revealed that with its 6-hour exposure, the most potent effect (lower concentrations of creatinine and "middle-sized" molecules in serum) was observed in the proximal portions of the small bowel. This phenomenon is likely to be attributable to greater vascularization and the maximal creatinine and "middle-sized" molecule concentration in these intestinal portions. With this, it was shown that the higher baseline concentrations of serum creatinine and "middle-sized" molecules were, the more actively they absorbed on the charcoal enterosorbent brand SKN in the intestine.
