Evaluation of the therapeutic potential of novel nanoparticle formulations of glutathione and virgin coconut oil in an experimental model of carbon tetrachloride-induced liver failure.

Abstract

Background: Acute liver failure (ALF) is a critical condition characterized by rapid liver dysfunction, leading to high mortality rates. Current treatments are limited, primarily supportive, and often require liver transplantation. This study investigates the potential of a novel nanoparticle formulation of glutathione (GSH) and virgin coconut oil (VCO) alone and in combination to enhance therapeutic outcomes in a rat model of ALF induced by orogastric carbon tetrachloride (CCl₄).

Methods: The study employed adult male Albino rats divided into ten groups, with ALF induced via a single oral dose of CCl₄. Various treatment regimens were administered over seven days, including conventional and nanoparticle forms of GSH and VCO and their combinations. The efficacy of treatments was evaluated through biochemical analysis of liver function markers, oxidative stress indicators, inflammatory biomarkers, and histopathological examinations. Nanoparticles were synthesized using established methods, and characterization techniques were employed to ensure their quality and properties.

Results: The nanoparticle formulations significantly improved liver function, as indicated by reduced serum levels of alanine aminotransferase and aspartate aminotransferase, alongside decreased oxidative stress markers such as malondialdehyde. Furthermore, they reduced tumor necrosis factor alpha and interleukin-1 beta inflammatory markers. Histological analysis revealed reduced hepatocellular necrosis and inflammation in treated groups compared to controls. Also, decreased nuclear factor-kappa B was detected by immunohistochemical analysis.

Conclusion: The findings show that the nanoparticle mixture of GSH and VCO effectively reduces liver damage in ALF. This suggests a promising drug-based approach for improving liver regeneration and protection. This innovative strategy may pave the way for new therapeutic interventions in the management of ALF.
