aflatoxin b 1/necrosis

Six types of animal-feed ingredients and swine mixed feeds from factories in northern Thailand were sampled for analysis of mycotoxins. Mycotoxins found in foodstuffs included aflatoxins, fumonisins, ochratoxins, T-2 toxin, vomitoxin and zearalenone. Samples of airborne dust generated while handling

Exposure to a nontoxic dose of bacterial endotoxin (lipopolysaccharide [LPS]) potentiates the hepatotoxicity of aflatoxin B(1) (AFB(1)). Because some of the pathophysiologic effects associated with LPS are mediated through tumor necrosis factor alpha (TNF-alpha), this study was conducted to explore

A 35-kg Duroc pig died 3 days after eating a ration containing aflatoxin B1, B2, G1, and G2. It had hemorrhagic enteritis and extensive midzonal necrosis in the liver. A 13-year-old Quarterhorse that died 2 days after eating moldy hay had hemorrhagic enteritis, fatty degeneration of the myocardium

Effect of ethanol pretreatment on acute hepatotoxicity and hepatic fat accumulation induced by aflatoxin B1 (AFB1) was followed up to 120 h in male Wistar rats. Pretreatment with 4 oral doses of ethanol (4.0 g/kg body wt. each) at 48, 45, 24 and 21 h prior to AFB1 (2.0 mg/kg body wt.) single

The present study was conducted to evaluate the adverse effects of an interaction between low levels of dietary aflatoxins (AF) and Eimeria tenella infection on broiler chicks. A set of 1-day-old chicks were raised for 35 days in the following groups: a control group, a group fed AF, a group fed AF

Aflatoxin B1, a metabolite of Aspergillus flavus is a potent hepatotoxic and hepatocarcinogenic mycotoxin. Lipid peroxidation and oxidative DNA damage are the principal manifestations of aflatoxin B1-induced toxicity which could be mitigated by antioxidants. Many plant constituents, e.g. flavonoids,

A study on the protective effect of alcoholic extract of the leaves of Ocimum sanctum on 3-methylcholanthrene (MCA), 7,12-dimethylbenzanthracene (DMBA) and aflatoxin B1 (AFB1) induced skin tumorigenesis in a mouse model has been investigated. The study involved pretreatment of mice with the leaf

OBJECTIVE Many studies have been showed transfer of aflatoxins, toxins produced by Aspergillus flvaus and Aspergillus parasiticus fungi, into milk. These toxins are transferred into the milk through digestive system by eating contaminated food. Due to the toxicity of these materials, it seems that

Species and sex differences of aflatoxin B1 (AFB1)-induced glutathione S-transferase placental form (GST-P) positive single hepatocytes have been investigated 48 h after an intraperitoneal injection of AFB1 to young male and female Fischer rats (2 mg AFB1/kg body wt) and male Syrian golden hamsters

This study aimed to investigate the effect of cysteamine hydrochloride (CSH) supplementation on the growth performance, opportunistic bacteria and enterotoxic markers, visceral lesions, glutathione turnover, and inflammatory factors of broilers fed diets contaminated with aflatoxin B1 (AFB1).

The sequential light microscopic changes in aflatoxin B1-induced liver tumors during chronic administration of glutathione were studied. The results suggest that necrosis of neoplastic hepatocytes plays an important role during the regression of tumor growth induced by glutathione.

These studies were conducted to investigate whether ascorbic acid protected guinea pigs from aflatoxin B1 (AFB1) toxicity. Young guinea pigs, fed either 0 (AA) or 25 mg (25 AA) or gavaged 300 mg ascorbic acid (300 AA) per day for 21 days, were gavaged with the LD50 dose of AFB1 on the 22nd day.
