Abstract

The purpose of the current study was to examine the neuroprotective effect of rutin against colistin-induced neurotoxicity in rats. Thirty-five male Sprague Dawley rats were randomly divided into 5 groups. The control group (orally received physiological saline), the rutin group (orally administered 100 mg/kg body weight), the colistin group (i.p. administered 15 mg/kg body weight), the Col + Rut 50 group (i.p. administered 15 mg/kg body weight of colistin, and orally received 50 mg/kg body weight of rutin), the Col + Rut 100 group (i.p. administered 15 mg/kg body weight of colistin, and orally received 100 mg/kg body weight of rutin). Administration of colistin increased levels of glial fibrillary acidic protein and brain-derived neurotrophic factor and acetylcholinesterase and butyrylcholinesterase activities while decreasing level of cyclic AMP response element binding protein and extracellular signal regulated kinases 1 and 2 (ERK1/2) expressions. Colistin increased oxidative impairments as evidenced by a decrease in level of nuclear factor erythroid 2-related factor 2 (Nrf-2), glutathione, superoxide dismutase, glutathione peroxidase and catalase activities, and increased malondialdehyde content. Colistin also increased the levels of the apoptotic and inflammatoric parameters such as cysteine aspartate specific protease-3 (caspase-3), p53, B-cell lymphoma-2 (Bcl-2), nuclear factor kappa B (NF-kappa B), Bcl-2 associated X protein (Bax), tumor necrosis factor-alpha (TNF-alpha) and neuronal nitric oxide synthase (nNOS). Rutin treatment restored the brain function by attenuating colistin-induced oxidative stress, apoptosis, inflammation, histopathological and immunohistochemical alteration suggesting that rutin supplementation mitigated colistin-induced neurotoxicity in male rats.
