Representative micrographs of the wall of the rat aortas from the control group (a and d), untreated diabetes group (b and e) and diabetes + telmisartan group (c and f). Decreased thickness of the medial layer was noted in both untreated diabetes and diabetes + telmisartan group, while focal disorganisation of elastic lamellae were seen in untreated diabetes group (b). Resorcin-fuchsin (a-c) and van Gieson (d-e). ▲ elastin lamellae are stained violet (resorcin-fuchsin). ● collagen fibres are stained red (van Gieson).
