Representative microvessel density (MVD) of (a) control and (b) treatment groups: immunostaining with CD31 antibody highlights vessels (arrows). Intratumoral MVD of the right tumor of the rabbit number 5 (control group) is 26.25 and the left tumor of the rabbit number 2 is 9.25 (original magnification, ×200).
