From: Alterations of the Rat Mesentery Vasculature in Experimental Diabetes

Spread mesenteric windows in which the vessels are clearly outlined after staining with toluidine blue. a, Part of mesenteric window from a control rat; and b, from a 3-months diabetic rat. Note the marked increase in the density of the microvascularization (length of the vessels and incidence of branching) in the mesentery window harvested from a diabetic animal (b), in contrast to that of a normal animal (a). Diabetes was induced by iv injection of STZ.
