Antioxidant mediated defensive potency of Caesalpinia bonducella nut on Acetaminophen-inebriated spleen and cardiotoxicity: Implications on oxidative stress and tissue morphology in an In vivo model

Overdosing on medications can be unintentional or deliberate. Acetaminophen (APAP) is a widely used over-the-counter analgesic and antipyretic drug. APAP overdose can induce spleen and cardiotoxicity apart from hepatotoxicity. Bonduc nut is well-known for its medicinal and therapeutic properties. More scientific data is necessary to be therapeutically relevant. This study examined the effects of Bonduc nut extract (BNE) on APAP-induced spleen and cardiotoxicity in Wistar albino rats. The rats were divided into five groups of six rats each. In vitro assays were carried out to analyze antioxidant activity and free radical scavenging activity in aqueous, ethanol, and methanol solvents in Bonduc nut powder. Total phenolic content, DPPH, catalase, and peroxidase activity were used to test antioxidant activity. The rats were euthanized after the study period to examine antioxidant parameters such as superoxide dismutase, catalase, reduced glutathione, and glutathione peroxidase, as well as lipid peroxidation and histopathology of the spleen and heart tissues. Results suggest that compared to other solvents aqueous has better Invitro antioxidant ability and the same extract significantly increased the antioxidant and reduced lipid peroxidation followed by restoring the tissue morphology in APAP-induced spleen and cardiotoxicity. The outcome of the study revealed that aqueous BNE has a significant protective efficacy against APAP-induced spleen and cardiotoxicity in Wistar albino rats.
