Succinyl trialanine p-nitroanilide hydrolytic activities in plasma and the aorta of rabbits experimentally immunized...

Experimental immunization of rabbits with soluble porcine elastin was performed. Elastase-like activities in plasma and the aorta were assayed using succinyl trialanine p-nitroanilide. A statistically significant increase in the elastase-like activity in plasma of the immunized animals was observed. Estimations of the elastase-like activity in the rabbit aorta showed the rise of analyzed parameters in the experimental group.
