- Paper Abstract
- Ethnopharmacological relevance: The ancient Chinese medicine book "Huangdi Neijing" reports that "the brain is the sea of marrow" and that the kidney "mainly induces bones to produce marrow". Therefore, Chinese medicine has a "kidney-brain axis" theory, but supporting evidence is lacking. In this study, curculigoside, the main component of the kidney-tonifying drug Rhizoma Curculiginis, was used to explore whether a kidney-tonifying drug could regulate the pathological state of the brain. Aim of the study: To explore the efficacy of curculigoside in protecting against ischemic brain injury (IBI) through the regulation of oxidative stress and NF-κB and PI3K/Akt expression. Materials and methods: Middle cerebral artery occlusion (MCAO) was used to induce IBI in rats, and curculigoside was administered. The degree of IBI, morphological changes and severity of nerve injury (using neurological severity scores; NSSs) in the rats were assessed. Enzyme-linked immunosorbent assays (ELISAs), Western blotting, and immunohistochemistry were used to evaluate changes in hydrogen peroxide (H 2 O 2 ), nitric oxide (NO), malondialdehyde (MDA), TNF-α, IL-1β, catalase (CAT), superoxide dismutase (SOD), nitric oxide synthase (NOS), NF-κB, PI3K and Akt levels. Results: Curculigoside significantly alleviated behavioral deficits and reduced the degree of cerebral ischemia in the rats. After curculigoside treatment, the levels of H 2 O 2 , NO, MDA, NOS, iNOS, TNF-α, IL-1β, intercellular adhesion molecule-1 (ICAM-1) and NF-κB in the ischemic area of the brain were significantly reduced. The activities of CAT, SOD, PI3K and Akt were significantly increased. Conclusion: Curculigoside is a potentially effective drug for the treatment of IBI.
