Abstract

Asiaticoside has potent pharmacological activity and broader pharmacological effects, including anti‑oxidant, antidepressant and hepatic protection effects, and the inhibition of tumor cell proliferation. However, the mechanism underlying the effects of asiaticoside on neurological pain in spinal cord injury (SCI) remain to be fully elucidated. Therefore, the present study investigated the specific mechanism underlying the beneficial action of asiaticoside in a SCI rat model. In the present study, Basso, Beattie and Bresnahan scores was determined to analyze the therapeutic effects of asiaticoside on the neurological function of the SCI rat model. The water content of the spinal cord was also determined to measure its effects on the SCI rats. Oxidative stress, levels of nitric oxide and inflammation were detected using commercial kits. Western blot analysis was used to measure the protein expression levels of p38‑mitogen‑activated protein kinase (MAPK) in the SCI rat. Asiaticoside effectively augmented the Basso, Beattie and Bresnahan scores of the SCI rats. Significant reductions in the water content of the spinal cord, the levels of inducible nitric oxide synthase (iNOS), and the activities of the nuclear factor‑κB p65 unit, tumor necrosis factor‑α, interleukin(IL)‑1β and IL‑6 were observed in the experimental animals. Furthermore, on examination of the oxidative stress‑associated parameters, increased production of malondialdehyde and decreased levels of superoxide dismutase, glutathione and glutathione peroxidase were detected in the SCI rat model. Asiaticoside also significantly suppressed the expression of p38‑MAPK, which indicated that the therapeutic effects of asiaticoside may be associated with the p38‑MAPK pathway. These data confirmed that asiaticoside attenuates SCI through antioxidant and anti‑inflammatory effects, and through inhibition of the p38‑MAPK mechanism.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Asiaticoside attenuates spinal cord injury in rat models by preventing oxidative damage, nitric oxide activity and production of pro-inflammatory cytokines, and by inactivating the p38-MAPK signalling pathway.

    “The results attested to the neuroprotective properties of asiaticoside in attenuating SCI which prevented oxidative damage, nitric oxide activity and the production of pro‐inflammatory cytokines. Furthermore, asiaticoside also inactivated the p38‐MAPK signalling pathway, which when expressed leads to the destruction of the blood–spinal cord barrier. 71”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
