[Early biological disorders in acute intestinal ischemia in the rat. Determination of blood phosphorus and serum alkaline phosphatase].

Though difficult, early diagnosis of acute intestinal ischemia is essential in order to improve the prognosis of this major affection. The possibility that early modifications in biological parameters could provide such data was explored. Serum alkaline phosphatase levels were unaltered, whereas blood phosphorus concentrations were increased during AII of arterial or venous origin in the rat. The latter test therefore provides an early specific indication of the diagnosis, the mechanism involved being liberation of phosphate ions from the intestine, enhanced by a functional renal insufficiency.
