Fig. 6From: Effects of tissue degradation by collagenase and elastase on the biaxial mechanics of porcine airwaysA The average cyclic loading and unloading stress–strain response of various lung regions, orientations and pre- and post-treatment responses and B average ± standard deviations of the hysteresis and energy loss between treatment, region, and orientation is shown. Hysteresis decreased after enzyme treatments in both orientations. Decreased energy loss was also evident post-treatment for all directions and regions and was lowest for the axial orientationBack to article page
