acetaldehyde and to a lesser degree phenobarbital , at concentrations which did not modify the activity of a preparation of hog kidney diamine oxidase , increased delta1 -pyrroline formation in kidney homogenate , which suggests that aldehyde-metabolizing enzymes present in this tissue may interfere with the yield of delta1 -pyrroline formation and that the use of acetaldehyde may give better information on kidney diamine oxidase activity .
