The study aims to assess the impact of various doses of red bull on kidney and pancreas of male albino rats. Thirty male albino rats were assigned to three groups (10 animals/ group). Control group (1) received standard diet and water, group 2 and group 3 received daily oral doses of 10 ml/kg/rat and 20 ml/kg/rat of the energy drink (red bull) respectively for 30 days. Under light microscope no tissue changes were seen in kidney and pancreas of control group. In group 2 red bull causes vacuolar degeneration as well as coagulative necrosis of renal tubular epithelium, vascular congestion in the glomeruli and in the interstitial space of the kidney, in addition to atrophy of the glomeruli, as regard to pancreas it causes vascular congestion of the islets of Langerhans, increase in the size of the islets, besides, necrosis of Langerhans cells. In group 3 red bull leads to more atrophic glomeruli, massive coagulative necrosis of renal tubular epithelium, marked vascular dilatation and congestion in the interstitial space and degenerative changes of the renal tubular epithelium, whereas the pancreatic tissue revealed reduction in the size of the islets of Langerhans, vacuolation and degeneration of their cells, necrosis of other islets with mononuclear inflammatory cells infiltration and degenerative changes of pancreatic acini. It is concluded that administration of red bull to rats for 30 days will affect the histological structure of kidney as well as pancreas and this effect is a dose dependent.
