Toll-like receptor (TLR) activation has been implicated in acetaminophen (APAP)-induced hepatotoxicity. Herein, we hypothesize that TLR3 activation significantly contributed to APAP-induced liver injury. In fasted wildtype (WT) mice, APAP caused significant cellular necrosis, edema, and inflammation in the liver, and the de novo expression and activation of TLR3 was found to be necessary for AP...

BACKGROUND Acetaminophen (APAP) overdose induces massive hepatocyte necrosis. Necrotic tissue releases high mobility group B1 (HMGB1), and HMGB1 contributes to liver injury. Even though blockade of HMGB1 does not protect against APAP-induced acute liver injury (ALI) at 9 h time point, the later time points are not studied and the role of HMGB1 in APAP overdose is unknown, it is possible that ne...

The aim of the present work was to investigate a new mechanism likely contributing to the toxic action of acetaminophen, especially to explore the possible inhibition of glutathione reductase through an acetaminophen-glutathione conjugate (APAP-SG). APAP-SG conjugate was synthesized by organic synthesis and purified by column chromatography. The inhibitory effect of the conjugate on two types o...

The aim of the present investigation was to investigate the nephro-protective activity of fruits extracts of Rubus ellipticus (Smith) at a dose of 200 mg/kg body weight on acetaminophen (APAP) induced naphro-toxicity in male albino rats. APAP significantly increased the levels of serum creatinine, serum urea, blood urea nitrogen and kidney weight while the volume of urine reduced. The pet.ether...

Paracetamol (APAP-Acetaminophen) has been used extensively as antipyretic drug. The purpose of this study was to evaluate the ameliorative role of silymarin or/and Nigella sativa extract against APAP-induced hyperlipidemia in male mice at the biochemical, levels. The mice were divided into seven groups (10/group). The first group was served as control. While, the second group was treated with d...

Acetaminophen (APAP) is a widely used analgesic and antipyretic drug. Generally, the therapeutic dose of APAP is clinically safe, however, high doses of APAP can cause acute liver and kidney injury. Therefore, the majority of previous studies have focussed on elucidating the mechanisms of APAP-induced hepatotoxicity and nephrotoxicity, in addition to examining ways to treat these conditions in ...

Objectives: Acetaminophen (APAP) toxicity is known to be common and potentially fatal. This study aims to investigate the protective effects of hydroalcoholic extract, remaining from Crocus sativus petals (CSP) against APAP-induced hepatotoxicity by measuring the blood parameters and studying the histopathology of liver in male rats. Materials and Methods: Wister rats (24) were randomly assigne...


 Introduction: Acetaminophen (APAP) is the most widely used over-the-counter antipyretic and analgesic medicine in children. Although hepatic failure death rare paediatric population, it one of important dangerous presentation acetaminophen induced toxicity There very sparse data regarding APAP acute liver our settings, hence this study was done to know clinical demographic profiles as we...

The role of lysosomes in acetaminophen (APAP) hepatotoxicity is poorly understood. Here, we investigated the impact of genetic and drug-induced lysosomal cholesterol (LC) accumulation in APAP hepatotoxicity. Acid sphingomyelinase (ASMase)(-/-) mice exhibit LC accumulation and higher mortality after APAP overdose compared to ASMase(+/+) littermates. ASMase(-/-) hepatocytes display lower threshol...

Hepatic injury induces inflammatory process and cell necrosis. Plantago major is traditionally used for various diseases. This study aimed to determine the anti-inflammatory property of P. major leaf extracts on inflammatory reaction following acetaminophen (APAP) hepatotoxicity. Thirty male Sprague-Dawley rats were divided into 5 groups, namely, normal control (C), APAP, aqueous (APAP + AQ), m...
