A 24 year old man with severe renovascular hypertension was diagnosed as having an arteriovenous malformation of the left kidney with an aneurysm of the renal artery 12 years after right nephrectomy. Surgical reconstruction proved unsuccessful, but subsequent autotransplantation of the lower segment of the kidney 18 hours later saved the patient. He made an excellent recovery and is now normotensive and able to lead a normal life.

Calcium-binding protein in the duodenal mucosa of uremic patients and normal subjects.

In the present study we measured the content and determined the localization of a calcium-binding protein (CaBP) in the intestinal biopsy specimen of ten patients with severe renal insufficiency and in eight healthy individuals. In each patient a biopsy specimen of the iliac crest was obtained for evaluation of the degree of osteodystrophy. The CaBP was isolated from human kidneys. Its identity with human intestinal CaBP was suggested by acrylamid gel electrophoresis. Specific antibodies against it were developed in rabbits. The content of CaBP in duodenal mucosa biopsy material was measured by quantitative radial immunodiffusion. Its mean value in the duodenum of patients with renal insufficiency was 3.65 +/- 1.14 mug; in that of normal persons, 10.80 +/- 3.20 mug/mg of protein in the supernatant. There was neither a correlation between the type and duration of renal insufficiency and the CaBP content of the specimens nor between the degree of renal osteodystrophy and CaBP content. In normal persons the specific immunohistological activity indicating the presence of CaBP was found uniformly along the brush border and basement membrane of duodenal epithelial and the goblet cells. In uremic patients the fluorescence was markedly reduced in the typical locations, especially in the brush border area.

Localization of calcium-binding protein in intestinal tissue by immunofluorescence in normal, vitamin-D-deficient and uraemic subjects.

Antiserum directed against calcium-binding protein isolated from human kidneys was used for the immunofluorescent localization of calcium-binding protein in human intestine and kidney. Frozen sections of intestine obtained by biopsy from normal persons were tested by the indirect fluorescent antibody technique. Specific fluorescence indicating the presence of calciumbinding protein was observed at both the basal and apical poles of the intestinal absorptive cells while the goblet cells appeared to fluoresce non-specifically. Treatment of rachitic children with 25-hydroxycholecalciferol generally restored the pattern of fluorescence seen in intestinal tissue from normal persons. Examinations of intestinal biopsies from uraemic patients yielded variable results.
