Sentences with phrase «dose animal cancer»

Not exact matches

The Food and Drug Administration has long permitted its use, but in recent years concerns about the chemical have grown as studies have indicated low doses of the substance can disrupt hormone systems in laboratory animals and possibly increase the risk of cancer or other serious illness.

Studies in experimental animals have linked high doses of food dyes to health problems, among them organ damage, cancer, birth defects, and allergic reactions.

Scientists have linked low doses of BPA to obesity, diabetes, thyroid disease, breast cancer, prostate cancer and other illnesses in lab tests on animals.

Although researchers have known that nitrites and nitrates at high doses can cause cancer in lab animals, de la Monte's results suggest that long - term, low - dose exposure to the compounds may be linked to chronic diseases in humans.

But the dogs had no major side effects from taking low doses of the drug, a worry because rapamycin impairs immune system function and could make animals (including people) who take it more vulnerable to infection or cancer.

Interestingly, while massive quantities of safrole caused liver cancer in lab animals, it seems that small doses may actually play a protective role for humans.

«With regards to the warnings that comfrey can cause cancer and liver disease, most herbal practitioners point out that those results were from studies that isolated the pyrrolizidine alkaloids and fed or injected them into animal subjects in doses far higher than any typical usage of comfrey leaf, and that comfrey leaf has been regularly ingested by thousands of people around the world without reported ill effects.»

Animals starting with the most cancer initiation (high - aflatoxin dose) developed substantially less foci when fed the 5 % protein diet.

Large enough doses of aflatoxin are a liver carcinogen in high doses (it's actually what T. Colin Campbell used to induce liver cancer in mice during his China Study crusade to indict animal protein).

On page 45 of The China Study, Campbell mocks the high doses of carcinogens used in animal studies to show that carcinogen exposure, rather than nutritional factors such as protein intake, produce cancer:

The rats were given humongous liver - destroying doses of the liver toxin to show that it was not the aflatoxin that caused the cancer; no, only the rats who got both the aflatoxin and the animal protein got the cancer.

When the aflatoxin dose is more moderate, animals eating a low - protein diet develop cancer while their higher - protein counterparts remain in mighty fine health.

High doses of rapamycin are already used in humans to fight cancer and prevent organ - transplant rejection, but at low doses, it has also been shown to slow aging and extend life span in several animals with few or no side effects.

While earlier studies had linked early - stage cancers and lower sperm counts in animals to low BPA doses, no study had ever linked exposure to female reproductive diseases.Not surprisingly, the plastics industry balked at the findings, labeling the scientists as biased and alarmist; they also rejected the BPA link to reproductive diseases as unfounded and based on uncertain science.

«[Animal tests] can include skin and eye irritation tests where chemicals are rubbed onto the shaved skin or dripped into the eyes of rabbits; repeated oral force - feeding studies lasting weeks or months to look for signs of general illness or specific health hazards, such as cancer or birth defects; and even widely condemned «lethal dose» tests, in which animals are forced to swallow massive amounts of a test chemical to determine the dose that causes death.»

In its June 1, 1984 issue, The Washington Post reported the issuance of a massive new report by the White House science office supporting the scientific consensus that «agents found to cause cancer in animals should be considered «suspect human carcinogens,»» and that «giving animals high doses of an agent is a proper way to test its carcinogenicity.»

Even these three chemical groups (and other food and cosmetic chemicals) are classified as «hazardous» by the EPA and FDA, because in high doses some can cause cancer and other problems in animals.

While the effect of these substances in humans is unclear, high doses are linked to cancer in animals, according to the National Cancer Instcancer in animals, according to the National Cancer InstCancer Institute.
