Abstract
To study the prognostic value of the acetylation phenotype in the formation of
intraperitoneal adhesions, 67 children were examined who were admitted with symptoms
of adhesive intestinal obstruction and had a history of laparotomy for complicated appendicitis.
To perform the acetylation reaction, we used the method for determining free and acetylated
norsulfazole in a six-hour urine sample after a single test dose of the drug. The amount of
free and total norsulfazole in the urine was determined by the Prebsting and Gavrilov
method modified by Timofeeva [10].
