AIM: Antibiotics have a great risk property, for this reason, the present work aimed to study the toxic effect of cefotaxime on histological examination of liver and kidney tissues as well as to detect the protecting role of Vitamin C. METHODS: Thirty-two male adult albino rats were divided into four groups each with (eight animals) as following: Group (1): As control group and they injected with normal saline. Group (2): They were injected with 200 mg/kg B.W. of cefotaxime. Group (3): They were injected with Vitamin C in dose 100 mg/kg B.W. 1 h before they inject with 200 mg/kg B.W. of cefotaxime. Group (4): It was given Vitamin C in dose of 100 mg/kg B.W. Animals in all groups were injected intraperitoneally as single daily dose for 14 consecutive days. RESULTS: Results of cefotaxime treated group revealed that a significant liver tissue changes as hepatocytic vacuolation, necrosis, cholestasis with sinusoidal congestion, and dilatation also induced a histopathological change in the kidney including tubular epithelial degeneration, cast formation in renal tubules, inflammatory cells infiltration in the interstitium, and few glomeruli showed eosinophilic material deposition at the wall of bowman capsule. Adding Vitamin C to third group induces amelioration in the histological features of liver and kidney seen in Group (2) while group of Vitamin C only showed a histological picture similar to control group. CONCLUSION: From this study, we can conclude that Vitamin C has important hepato-renal protective effect.

BACKGROUND: Nowadays energy drinks are markedly consumed by young people all over the world but till now there were only few literatures that describe their effect on the stomach and small intestine. AIM: The aim of the current study is to highlight the histopathological changes encountered in the stomach and small intestine that are induced by energy drinks. MATERIALS AND METHODS: Thirty adult male albino rats were divided into three groups: a control group given only standard diet and distilled water, a group given a low dose of Tiger energy drink (1 ml/100 mg/rat/day), and a group given a high dose of Tiger energy drink (2 ml/100 mg/rat/day). These drinks were given orally via gastric tube for 1 month duration. RESULTS: Histological assessment of different sections of the stomach and small intestine has revealed parietal cell hyperplasia with congestion of gastric mucosal blood vessels, moreover partial loss of intestinal villi with goblet cell hyperplasia was observed in group treated with low dose of Tiger. Increasing the dose of this drink resulted in mononuclear cell infiltration associated with goblet cell metaplasia which could be an early marker for gastric cancer, furthermore complete loss of intestinal villi and degenerative changes of epithelial cells were seen in intestinal sections. These pathological changes seem to be dose related. CONCLUSION: There is a high risk on the rat’s stomach and small intestine in chronic consumers of energy drinks particularly when taken with no limits. Further work is recommended to delineate the exact mechanism of the pathological findings induced by energy drinks.
