An approach to the toxicity and toxicokinetics of aflatoxin B1 and ochratoxin A after simultaneous oral administration to fasted F344 rats.
Humans are exposed to the hepatotoxic aflatoxin B1 (AFB1) and nephrotoxic ochratoxin A (OTA) through diet. However, kinetic and toxicological data after their co-administration are scarce. In this study, a single oral dose of AFB1 (0.25 mg/kg bw)+OTA (0.5 mg/kgbw) was administered to fasted F344 rats. Blood, liver and kidney were harvested at different timepoints for mycotoxins quantification, ...
متن کاملEffects of fasting and gender on ochratoxin A toxicokinetics in F344 rats.
Ochratoxin A (OTA) is a mycotoxin that causes renal tumors in rats, particularly in males. In previous kinetic studies performed in fed conditions (Vettorazzi et al., 2008), mature F344 male rats presented a significantly lower OTA bioavailability than females and young animals. The objective of the present study was to evaluate two factors which could explain this different kinetic profile: th...
متن کاملNinety-day toxicity and single-dose toxicokinetics study of alpha-glycosyl isoquercitrin in Sprague-Dawley rats.
alpha-Glycosyl isoquercitrin (AGIQ) is highly absorbable and has been shown to possess antioxidative properties. Based on a favorable safety profile, it has been confirmed as generally recognized as safe (GRAS) compound by the FDA. Nevertheless, safety and toxicity information for AGIQ is still sparse. Therefore, the aim of this study was to test the safety and toxicokinetics of AGIQ in a 90-da...
متن کاملEffects of quercetin on bisphenol A-induced mitochondrial toxicity in rat liver
Objective(s): Recognized as a distinguished environmental and global toxicant, Bisphenol A (BPA) affects the liver, which is a vital body organ, by the induction of oxidative stress. The present study was designed to investigate the protective effect of quercetin against BPA in hepatotoxicity in Wistar rats and also, the activity of mitochondrial enzymes were evaluated...
متن کاملThe protective effect of quercetin against hepatotoxicity induced by doxorubicin in male rats
Quercetin is one of the major flavonoids finding in many fruits and vegetables. Quercetin has many health promoting advantages such as improvement of allergic, arthritis disorder, and reduction of cancer and cardiovascular risk. The aim of this study was to examine hepatoprotective effects of quercetin on doxorubicin induced toxicity in animal model. Thirty male Wistar rats (200-230 g) were ran...
