According to a study published by "Journal of ethnopharmacology", Reinwardtia indica Dumort. protects against ponatinib-induced cerebral ischemia in adult zebrafish by attenuating oxidative stress, neuroinflammation, mitochondrial dysfunction, and neurotransmitter dysregulation. In the study, zebrafish subjected to a 24 h ischemic insult were treated with the hydroalcoholic leaf extract of R. indica for 7 consecutive days. The treatment significantly reduced lipid peroxidation and increased the antioxidant enzyme activity of SOD and catalase. Furthermore, the extract reduced levels of inflammatory cytokines, specifically TNF-α and IL-1β, while restoring levels of glutamate, GABA, acetylcholine, serotonin, dopamine, and noradrenaline. These results indicate that R. indica may be a promising therapeutic candidate for mitigating the effects of cerebral ischemia.
