in the present study , the lysate of blood platelets free of detectable neutrophils was examined for elastase-like activity using tertiary-butyloxycarbonyl ( tboc ) -ala-ala-pro-ala-aminomethyl coumarin ( i ) , tboc-ala-ala-pro-val-aminomethyl coumarin ( ii ) , and succinyl-tri-ala-rho-nitroanilide ( sapna ) , and for elastolytic activity using 3h-labeled dog and human lung elastins .
