Selective chemisorption and detoxification of aflatoxins by phyllosilicate clayAbstract Practical and effective strategies for the detoxification of aflatoxins are critically needed. We have shown that a phyllosilicate clay (HSCAS): i) tightly binds aflatoxins in aqueous solutions, including milk; ii) markedly decreases the bioavailability of radiolabeled aflatoxins; iii) greatly diminishes aflatoxicosis in young animals, i.e., rats, chickens,... ...

Economic losses and decontaminationAbstract Mycotoxin contamination of crops may cause economic losses at all levels of food and feed production including crop and animal production, and crop distribution and processing. The national economy would be affected adversely by losses incurred by crop and livestock producers and the multiplier effect this has on other industries as a result of the reduced ... ...

Antitumor effect of plant lectinsAbstract This review examines the literature data concerning the biological activity of plant lectins. Numerous studies have reported that these substances possess toxic, cytotoxic, antitumor, and anticarcinogenic properties. A brief description of the biological properties of plant lectins, as well as the effect of plant lectins on normal and malignant cells and th... ...

Worldwide regulations for mycotoxins in 1994Abstract Since the discovery of the aflatoxins in the 1960s, regulations have been established in many countries to protect the consumer from harmful effects of mycotoxins that may contaminate foodstuffs. Various factors play a role in the decision‐making process of setting limits for mycotoxins. These include scientific factors such as availability of survey data, ... ...

“Lupinosis”‐Like lesions in mice caused by ustiloxin, produced by Ustilaginoieda virens: A morphological studyAbstract A crude toxin, obtained by methanol‐extraction of a water extract of false smut balls (INA‐KOUJI in Japanese) caused by Ustilaginoidea virens on rice panicles, was injected into mice intraperitoneally. Single injection of 100 or 200 mg/kg body weight of the extract was not lethal but caused acute, occasional necrosis of hepatocyte... ...

Salt clean‐up procedure for the determination of domoic acid by HPLCAbstract Domoic acid (DA) was first reported in mussels from Prince Edward Island, Canada, in 1987. It reappeared in anchovies and pelicans from Monterey Bay, California, in 1991. Later that year, domoic acid was found in razor clams and Dungeness crabs along the Washington and Oregon coasts. Since the initial outbreak, a variety of analytical methods for the detect... ...

Brazilian baccharis toxins: Livestock poisoning and the isolation of macrocyclic trichothecene glucosidesAbstract Samples of the toxic Brazilian plant, Baccharis coridifolia , which is reponsible for numerous cases of livestock poisoning in southern Brazil and Argentina, were collected during the growing season, and the toxicities in calves of the plant materials were correlated with the levels of macrocyclic trichothecenes present. Female pla... ...

Apoptotic cellular damage in mice after T‐2 toxin‐induced acute toxicosisAbstract By histopathologic, electron microscopic, and immunochemical observation, the mechanism of cellular death was investigated in thymus, spleen, and liver of mice given intraperitoneally sublethal doses of T‐2 toxin, a trichothecene mycotoxin. In the thymus and spleen of mice given 5.0 mg/kg body weight of T‐2 toxin and killed 12 hours later, a massive cellula... ...

Some reflections on establishing a community legislation on mycotoxinsAbstract A Community legislation on mycotoxins is essential to protect public health and to avoid trade barriers and competition distortions. Maximum permitted levels in food are to be fixed. Some orientations for this purpose are indicated. The verification of the compliance with maximum permitted levels shall need suitable analytical methods. Up to... ...

Effects of sterigmatocystin and T‐2 toxin on the induction of unscheduled DNA synthesis in primary cultures of human gastric epithelial cellsAbstract Primary cultures of human gastric epithelial cells were tested for induction of unscheduled DNA synthesis (UDS) by Sterigmatocystin (ST) and T‐2 toxin. Autoradiographic results indicated that ST (10−6 ‐10−4 M) induced UDS in the presence of S9 activation system. The repair rates were 24‐91% (netgr... ...
