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...

Renal effects of acetaminophen (APAP) were studied in rats pretreated with probenecid to analyze whether acute APAP-induced nephrotoxicity could be related to a probenecid-sensitive transport system for APAP or its S-derived conjugates. The administration of probenecid (200 mg/kg b.wt. i.p.) 30 min before APAP administration (1000 mg/kg b.wt. i.p.) improved urine flow rate and protected against...

Background: Paracetamol (APAP) is the most famous drug used in the world to relieve of pain and used as an antipyretic. Paracetamol overdose induces liver damage and is a well known hepatotoxic drug. This study was aimed to determine the incidence of acidosis in acetaminophen overdose with the time of NAcetyl Cystiene (NAC) administration and correlation of late acidosis and death in acetaminop...

We read with interest a recent paper by Van Summeren et al. (2011), who reported protein expression changes in HepG2 cells after exposure to various model drugs for 72 h. According to the authors, the objective of this investigation was to explore ‘‘new screening methods that address toxicological hazards early in the drug discovery process’’ and to use ‘‘proteomics techniques to gain further i...

The involvement of the canalicular multidrug resistance protein 2 (Mrp2) in the hepatobiliary excretion of acetaminophen (APAP)-glutathione (GSH) conjugate and its derivatives was investigated using transport-deficient (TR- rats. Although no differences in the biliary concentration of APAP itself were detected between normal Wistar and TR- rats, significant differences in the biliary dispositio...

Acetaminophen (APAP) intoxication is a common cause of hepatic toxicity and life-threatening hepatic failure. However, few studies have investigated the possible association between APAP intoxication and acute kidney injury (AKI). We constructed a retrospective cohort study to clarify the relationship between APAP intoxication and the risk of AKI.We identified patients with APAP intoxication an...

Gender is an important factor in pharmacokinetics and pharmacodynamics. In the current study, gender difference in acetaminophen (APAP)-induced hepatotoxicity has been examined. Male and female mice were injected with a toxic dose of APAP (500 mg/kg, ip). Female mice were resistant to the hepatotoxic effects of APAP, depicted by serum alanine aminotransferase and sorbital dehydrogenase activiti...

Preplacement of compensatory tissue repair (CTR) by exposure to a nonlethal dose of a toxicant protects animals against a lethal dose of another toxicant. Although CTR is known to heteroprotect, the underlying molecular mechanisms are not completely known. Here, we investigated the mechanisms of heteroprotection using thioacetamide (TA): acetaminophen (APAP) heteroprotection model. Male Swiss W...

The goal of the present study was to compare hepatic toxicogenomic signatures across in vitro and in vivo mouse models following exposure to acetaminophen (APAP) or its relatively nontoxic regioisomer 3'-hydroxyacetanilide (AMAP). Two different Affymetrix microarray platforms and one Agilent Oligonucleotide microarray were utilized. APAP and AMAP treatments resulted in significant and large cha...

Acetaminophen (paracetamol, APAP) has a worldwide usage. Nevertheless, overdosing may induce severe toxicity. Dexpanthenol (DXP) is the alcohol provitamin form of vitamin B5 with antiinflammatory and antioxidant efficacy. In the present study, the biochemical and histological protective effects of DXP against acetaminophen-induced oxidative hepatorenal damage were examined. Rats were divided in...
