[Possibilities for using emergency abdominal ultrasound study and its significance in acute diseases of the abdominal cavity].

Studies were conducted by the authors' of this paper into the diagnostic value of ultrasonic examination to clear up suspicion of acute abdominal problems, with 381 examinations being actually evaluated. Definitely valid diagnosis was obtained from the method in 37.7 per cent of these cases. The tentative diagnosis was invalidated in 18.2 per cent. The results are compared with literature data. Continued systematic use of the approach is recommended. It would bring down the time required for diagnosis and might provide another possibility of supporting the diagnostic effort which is quite difficult, when it comes to acute abdominal problems.

Normal serum albumin transfer from blood to small intestine and its role in albumin breakdown.

131I-albumin transfer into isolated segments of the small intestine has been determined following the intravenous injection of human 131I-albumin in 23 dogs. The importance of different intestinal segments in the normal degradation of albumin has been established. The slope of the serum disappearance curve was unaltered with proves that the applied technique had no damaging effect. Albumin leakage was not uniform in the whole length of the small intestine. It was highest in the duodenum (0.241 +/- 0.014 ml/10 cm intestine/hour). This was followed by the jejunum (0.142 +/- 0.022 ml/10 cm intestine/hour), and the smallest vally quantity of albumin leakage corresponded to a plasma volume of 14.49 ml in the duodenum, 27.16 ml in the jejunum, and to 23.76 ml in the ileum. The relationship of albumin leakage and catabolism revealed that protein bound activity (transferred and regained) in the dudodenum, in spite of the shortness of this section of the intestine, was responsible for 11.72 +/- 1.70% of total catabolism, that in the jejunum for 21.28 +/- 3.69%, and that in the ileum for 19.24 +/- 3.64%. The sum of the catabolism of the three intestinal segments yielded 52.26 +/- 6.65% of the total catabolism. After correction with a proteolytic factor, this value was 68.44%. Our examinations have established that the small intestine is the main region of normal albumin breakdown.

Effect of acute intestinal obstruction on the leakage of albumin from blood into the small intestine.

The effect of a simple, low intestinal obstruction has been investigated in dogs on the leakage of 131I-serum albumin from the circulation into the intestine. An increase leakage has been demonstrated. In the distended segment of the intestine above that ligation a significant increase in protein-bound radioactivity, from the normal value of 0.082 plus or minus 0.012 ml/10 cm intestine/hour to 0.276 plus or minus 0.068 ml/10 cm intestine/hour, was obseved which means a more than 3fold increase. The values for albumin leakage did not change in the more proximal segments of the intestine less involved in the distension namely in the duodenum and the jejunum, furthermore in the ileal segment below the ligation. The increase in albumin liadage observed during intestinal obstruction resulted in 33% rise of total catabolism.
