In the last 4 weeks of the experiment, eitherDMSO or APC (25 mg/kg, dissolved in DMSO) was applied to the HFD+DMSO or HFD+APC groups. Lipid profiles and leptinvalues were measured in blood serum. Renal and bladder oxidant/antioxidant parameters, histological changes in the tissues, NOX-2-,nuclear factor kappa B (NF-ĸB)-immunopositive and apoptotic cells were evaluated.Results: At the end of the experiment, leptin, cholesterol, and triglyceride levels were higher and high-density lipoprotein levels werelower in the HFD and HFD+DMSO groups compared to controls. In these experimental groups, an increase in malondialdehyde,8-hydroxy-deoxyguanosine and myeloperoxidase levels and a decrease in glutathione levels, as well as an increase in collagen, NOX-2– and NFĸ-B-immunopositive and apoptotic cells were found. Also, a deterioration in kidney and bladder morphology was observed.All these biochemical and histopathological findings improved in the HFD+APC group.Conclusion: High-fed diet causes renal and bladder injury by increasing NOX-2 activity and inflammation via oxidative stress. APCmight alleviate tissue injury by inhibiting oxidative stress. KW - Apocynin KW - Bladder KW - High-fat diet KW - Kidney KW - Oxidative stress CR - Bin-Meferij MM, El-Kott AF, Shati AA, Eid RA.
