Serum creatine phosphokinase (CK) and alkaline phosphatase (ALP) rise after mesenteric infarction; it is not known which one rises earlier or which one has the greater elevation. This experiment compared and contrasted the elevations in both these enzyme systems after acute small bowel infarction. Isoenzymes of both systems were analyzed to determine if any qualitative changes occurred. After baseline blood samples had been drawn, 10 dogs had midline laparotomies under general anesthesia. Each was assigned to one of two groups according to a randomized block design. Controls (CON) were closed after exploration (N = 5). The infarction (INF) group had ligation and division of the arteries to the jejunum and ileum (N = 5). Blood samples were obtained from both groups at 3, 6, 9, 12, 24, and 27 hr after surgery. Sera were analyzed for total CK and ALP activity by automated spectrophotometry. Isoenzymes were determined by agarose gel electrophoresis. Serum CK rose faster and to a higher level than ALP after small bowel infarction (470 ± 181 vs 196 + 28 IU/liter). CK-BB was a better marker of small bowel necrosis than was intestinal ALP. The elevation of both CK and ALP by 12 hr after infarction may be a diagnostic aid if similar changes occur in humans.
