Fig. 6From: Autonomic remodeling may be responsible for decreased incidence of aortic dissection in STZ-induced diabetic rats via down-regulation of matrix metalloprotease 2VG staining of thoracic aorta. Elastic fiber seemed to be thicker in DM rats. During aortic dissection, elastic fiber became irregular arranged, fiber fragmentation and inflammation infiltration could be observed (black arrow). Diabetic rats relatively preserved elastic fiber after URAS and BPAN treatmentBack to article page
