Optical micrographs of tissue sections stained with hematoxylin/eosin. a and b Photos of liver sections from control (a) and MDMA-treated rats (b). MDMA-treated rats showed sinusoidal dilatation (green arrows) with a marked cellular vacuolization in the periportal regions. c and d Photos from heart sections of controls (c) and MDMA-treated rats (d). In d scattered cardiomyocytes with signs of intracellular oedema (yellow arrows) can be observed, as identified by the reduced cytoplasmic staining. e and f Photos of kidneys sections from controls (e) and MDMA-treated rats (f). In f a slight interstitial oedema (blue arrows), detected by the enlarged space between the tubular structures, can be observed
