    The objective of the present study is the treatment of oxidative damage caused by acrylamide induced oxidative stress in rats with the administration of a strong antioxidant, namely crocin. High acrylamide (AA) levels have genotoxic, carcinogenic and neurotoxic effects on living organisms. In the present study, 40 Wistar rats were randomly divided into four equal groups. These groups were control, acrylamide (25 mg/kg), crocin (50 mg/kg), acrylamide + crocin (25 mg/kg acrylamide and 50 mg/kg crocin) groups. At the end of the application, biochemical and histological variations were examined in liver and blood samples. It was observed that acrylamide administration significantly decreased liver GSH and TAS levels when compared to the control group. On the contrary, it was also observed that AST, ALT, ALP, SOD and CAT activities and TOS and MDA levels increased as a result of acrylamide administration. Histopathological examinations demonstrated inflammatory cell infiltration, hepatocellular necrosis and hemorrhage areas in AA group liver sections. Furthermore, intracytoplasmic vacuolization was detected in hepatocytes. After crocin treatment, it was observed that GSH and TAS levels increased while AST, ALT, ALP, SOD and CAT activities and TOS and MDA levels decreased. Significant decreases were observed in inflammatory cell infiltration and vascular congestion in liver sections and intracytoplasmic vacuolization in hepatocytes after the crocin treatment, while no hepatocellular necrosis and hemorrhages were observed. In the present study, it was demonstrated that crocin treatment removed acrylamide induced liver damage due to the strong antioxidant properties of crocin. © 2017 Elsevier Masson SAS

    Investigation of the protective effects of crocin on acrylamide induced small and large intestine damage in rats
    (Taylor and Francis Ltd, 2018) Gedik S.; Erdemli M.E.; Gul M.; Yigitcan B.; Gozukara Bag H.; Aksungur Z.; Altinoz E.
    We investigated repair of acrylamide (AA) induced damage in intestines by administration of crocin. We used 40 male Wistar rats in four groups of 10 animals: control, AA, crocin, and AA + crocin groups. We investigated biochemical and histological changes to small and large intestine. AA ingestion decreased glutathione (GSH) levels and total antioxidant status (TAS) in the intestine compared to the control group, while superoxide dismutase (SOD) and catalase (CAT) activities, and total oxidant status (TOS) and malondialdehyde (MDA) levels were increased. Villi were shortened and villus degeneration was observed in ileum of the AA group. Degeneration of surface epithelium and Liberkühn crypts were observed in colon sections. GSH and TAS levels increased after administration of AA together with crocin, while SOD and CAT levels and TOS and MDA levels decreased; significant recovery of histological damage also was observed. We found that crocin exhibits protective effects on AA induced small and large intestine damage by inhibiting oxidative stress. © 2018, © 2018 The Biological Stain Commission.
