[Phosphatase activity of the neutrophils in acute appendicitis in children].

Phosphatase activity of neutrophils was studied in 342 patients directed to the hospital with the diagnosis of acute appendicitis, and in 56 healthy children. The index of phosphatase activity of neutrophils (IPAN) was found to be considerably increased in all forms of appendicitis in childhood. An intensity of the reaction depends on the form and terms, elapsed since the disease onset. The determination of IPAN in the complex with clinical findings could be utilized for the differential diagnosis purposes in investigation of patients suspected of acute appendicitis, while in the postoperative period - for estimating a gravity of the course and prognosis of the disease.
