Abstract

Determination of the serum level of intestinal fatty acid-binding protein has been used to detect rat intestinal ischemia following ligation or 30-min occlusion of the superior mesenteric artery. The normal values were under the minimal detectable level of less than 2 ng/ml in all the 10 rats. The serum fatty acid-binding protein level increased rapidly, to 340.7±54.6, 438.5±40.1, 388.1±37.4, and 292.2±95.7 ng/ml (P<0.01) at 1, 2, 4, and 8 hr after ligation respectively. It also increased, to 347.2±127.7 ng/ml (P<0.01) at 1 hr, after a 30-min transient occlusion and then returned to a normal level. Histological studies showed destruction of the villi, disappearance of the mucosa, and transmural necrosis with the progress of time after ligation, while no remoarkable morphological change was observed following 30-min transieent occlusion. These observations strongly suggest that the intestinal fatty acid-binding protein is a useful biochemical marker for intestinal ischemia, particularly in the early reversible phase.
