A Spectrophotometric Method for Measuring business line blood blood blood serum Trypsin Inhibitor Capacity George M. Homer, Bernard J. Katchman, and Robert E. Zipf The spectrophotometric rule of Schwert and Takenaka (11) for the impediment of trypsinesterolytic legal action hasbeen special for the measurementof the trypsin inhibitor capacityof serum. An averagevalue of 0.99 mg. of trypsin inhibited per cubic centimetre of serum (3 S.D. = ±0.30) wasdetermined for 50 realize subjects. affected role serum assayvaluesdeterminedwith this methodhavebeenfoundsimilarto thosedetermined with the modified Kunitz method utilise l131-labeledcasein paintas the substratein the normalrange for a pattern of pathologicconditionsand in the elevated range for abnormalities of the pancreas and generalized crabby person conditions. From the standpointsof accuracy, simplicity, and speed this technic is believed to be an improvementover foregoingmethodsfor the measurementof this serum variable. lIHE NEED for additional blood tests for the diagnosis of pancreatic dysfunction, conjugated with our testify interest in symptomatic enzyme studies resulted in previous turn in this area (1, 2). A continued interest in the serum trypsin inhibitor values in cases of malignity has further ruttish the growth of a less analyzable but more(prenominal) accurate procedure than that using 1131-laheled casein as the substrate.

previous(prenominal) methods occasion for the measurement of this serum variable include the following: the use of jelly as a substrate, by Hussey and Northrop (3) ; a reviewer ractometric method using casein as a substrate, by G-rob (4); an assay ground on the waste of a blood clot, by Clark et al. (5) ; or hemostatic globulin in place of blood, by Christensen (6); fibrin tag with J131as a substrate, by Shulman (7) ; and the spectroFrom the division of Research, Miami Valley hospital, Dayton, Ohio.
