Abstract

In the city of Antigo, Wisconsin, fluoridation of the public water supplies was initiated in 1949. ·It was discontinued in November 1960, and reinstituted in October 1965, A striking increase in the rate of deaths from heart disease occurred. in Antigo hnmediately following the introduction of fluoridation in 1949 and following its resumption in 1965. This trend was also evident when the death rates from heart disease in Antigo were compared with those of the United States as a whole. Among older individuals, the rise in mortality after initiation of fluoridation was much higher than among younger people.

  • Effect of chronic exposure to sodium fluoride and 7,12- dimethylbenz[a]anthracene on some blood parameters and hepatic, renal, and cardiac histopathology in rats.

    This study aimed to investigate the effects of both sodium fluoride (NaF) and 7,12-dimethylbenz[a]anthracene (DMBA), both separately and in combination, on some blood parameters and hepatic, renal, and cardiac histopathology in rats. Forty male Wistar albino rats, weighing 250–300 g, were randomly divided into one control and three experimental groups

  • Syndrome of endemic arsenism and fluorosis

    Sixty- five patients in Xinjiang with syndrome of endemic arsenism and fluorosis (SEAF) were investigated clinically from March 1982 to August 1989. SEAF is a kind of chronic syndrome resulting from the combined, harmful effects of two trace elements, arsenic and fluorine. Peripheral neuritis and cardiovascular changes were observed in

    Excerpts: Summary Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish exposure standards for contaminants in public drinking-water systems that might cause any adverse effects on human health. These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary

    In this study, several lines of evidence are provided to show that Na+ , K+ -ATPase activity exerts vital roles in normal brain development and function and that loss of enzyme activity is implicated in neurodevelopmental, neuropsychiatric and neurodegenerative disorders, as well as increased risk of cancer, metabolic, pulmonary and

  • Effects of melatonin and epiphyseal proteins on fluoride-induced adverse changes in antioxidant status of heart, liver, and kidney of rats

    Several experimental and clinical reports indicated the oxidative stress-mediated adverse changes in vital organs of human and animal in fluoride (F) toxicity. Therefore, the present study was undertaken to evaluate the therapeutic effect of buffalo (Bubalus bubalis) epiphyseal (pineal) proteins (BEP) and melatonin (MEL) against F-induced oxidative stress in heart,

  • Fluoride & Arterial Calcification

    The major change involved with cardiovascular disease is development of atherosclerosis in critical arteries, which is partially characterized by vascular calcification. The level of coronary artery calcification is thought to be the most important indicator of future cardiovascular events. Increased arterial calcifications have frequently been reported in those with skeletal fluorosis

  • Fluoride & Electrocardiogram Abnormalities

    An electrocardiogram (ECG) is a diagnostic test that measures the electrical activity of the heart. An ECG can reveal heart rate, heart rhythym (i.e. steady or irregular), and the strength and timing of the heart’s natural electrical signals. ECGs are described in terms of “waves” (e.g. amplitude and duration). Problems

  • Fluoride & Arteriosclerosis

    Healthy arteries are flexible and elastic, allowing efficient transfer of blood and nutrients from the heart to the rest of the body. Arteriosclerosis refers to a stiffening of the arteries, including loss of elasticity. This is a slow, progressive disease that may begin early in life from damage to the

  • Fluoride & Myocardial Damage

    Structural damage to the heart resulting from fluoride toxicity has been observed in numerous human and animal studies. The general features of this damage include cloudy swelling, vacuolization or vacuolar degeneration, hemorrhages, interstitial edema, fibrous necrosis, dissolution of nuclei, and thickening of the vessel walls in the heart muscle (Basha

  • Fluoride, Blood Pressure and Hypertension

    Individuals with blood pressure readings that exceed 140/90 are considered hypertensive. Hypertension can increase the risk of stroke, heart attack, heart failure, aortic aneurysms, and peripheral arterial disease. An association between increased fluoride in ground water and increased prevalence of hypertension has been observed, especially among adult males (Amini et
