in this survey aflatoxin contamination of fifty two samples of raw milk and nine samples of commercial milk were determined by t.l.c. method. the results showed that 92.31% of the samples of raw milk and all the samples of commercial milk were contaminated by aflatoxin m1 and m2. none of the samples contained alatoxin b1, b2, g1 and g2. the maximum amounts of 23/. g/lit and 20.1 g/lit were foun...

The relative contribution of, and possible mechanism of interaction between, aflatoxin and hepatitis B virus (HBV) in the development of primary hepatocellular carcinoma can be better investigated now that markers of individual exposure to both factors are available. In this study, blood samples were collected over a 1-month period from 117 children aged 3 to 4 years, resident in Kuntair or Ker...

In this study the β-lactoglobulin fibrillation, in the presence or absence of lead ions, aflatoxin M1 and curcumin, was evaluated using ThT fluorescence, Circular dichroism spectroscopy and atomic force microscopy. To investigate the toxicity of the different form of β-Lg fibrils, in the presence or absence of above toxins and curcumin, we monitored changes in the level of reactive oxygen speci...

The present study was conducted to observe the seasonal variation in aflatoxin M1 and nutritional quality of milk along informal marketing chains. Milk samples (485) were collected from three different chains over a period of one year. The average concentrations of aflatoxin M1 during the autumn and monsoon seasons (2.60 and 2.59 ppb) were found to be significantly higher (standard error of the...

The objective of this experiment was to monitor plasma levels of aflatoxin B1 (AFB1) aflatoxin B2 (AFB2), aflatoxin G1 (AFG1), aflatoxin G2 (AFG2) and aflatoxin M1 (AFM1) in lactating dairy cows fed afltaoxin contaminated corn. Seven lactating Holstein cows were given a bolus of a naturally contaminated corn meal assuring an intake of 4.9mg AFB1, 1.01mg AFB2, 10.63mg AFG1 and 0.89mg AFG2. Vitam...

We isolated two strains of Aspergillus flavus from a lung lesion and a skin lesion at autopsy from a patient with acute myelogenous leukemia complicated with fungal infection. An attempt was made to detect aflatoxins in culture filtrates of those isolates and the tissue extract of the lung lesion through the techniques of thin-layer chromatography (TLC), densitometry and high-performance liquid...
