The effect of ascorbic acid (AA) and butylated hydroxyanisole (BHA) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for AA and BHA) in diet containing 1 ppm total aflatoxin (AF: 76.45% AFB1, 10.52% AFB2, 9.89% AFG1 and 3.14% AFG2). A total of 300 day-old broiler chicks were divided into ten treatment groups (T1=control; T2...

Purebred Duroc gilts were fed 0, 15, 30, or 60 ppm of supplemental copper with 100 or 200 ppm of supplemental iron throughout four reproductive cycles. Traits studied included: gestation, lactation, and weaning-to-estrus weight changes; total and live pigs farrowed; total and live pig birth weights and weaned weights at 3 weeks of age; and hemoglobin, hematocri t and plasma copper and iron of s...

The purpose of this study was to examine the effects on humans of exposure to carbon dioxide (CO2 ) and bioeffluents. In three of the five exposures, the outdoor air supply rate was high enough to remove bioeffluents, resulting in a CO2 level of 500 ppm. Chemically pure CO2 was added to this reference condition to create exposure conditions with CO2 at 1000 or 3000 ppm. In two further condition...

Perinatal iron deficiency (PID) has been reported to induce developmental abnormalities, including cardiovascular complications in rats. These complications are believed to be "programmed" by an aberrant perinatal environment because the changes persist long after the insult is corrected (ie, despite subsequent iron replenishment). Little is known about the mechanisms by which PID affects blood...

There is considerable interest in the role of metals such as iron, copper, and zinc in amyloid plaque formation in Alzheimer's disease. However to convincingly establish their presence in plaques in vivo, a sensitive technique is required that is both quantitatively accurate and avoids isolation of plaques or staining/fixing brain tissue, since these processes introduce contaminants and redistr...

the effects of two iranian medicinal plants including zataria multiflora and geranium pelargoniumwere evaluated on growth-inhibiting of some toxigenic fungi such as aspergillus flavus, a. parasiticus, a.ochraceus and fusarium verticillioides. in this study, standard z. multiflora and g. pelargonium essentialoils (eos) were diluted in 0.01% dimethyl sulfoxide. different dilutions of z. multiflor...

Previous studies on the reproductive toxicity of boric acid have indicated that male rodents suffer testicular atrophy after treatment. There were, however, no studies of the potential effects on female fertility or on the neonate. In addition, no study described the development of the testicular lesion, thought to be related to the mechanism of toxicity. A Reproductive Assessment by Continuous...
