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.

Protective effect of quercetin against sodium fluoride induced oxidative stress in rat's heart
The antioxidative and cardioprotective properties of quercetin were investigated against sodium fluoride (NaF) induced oxidative stress in rat hearts. Experimental rats were divided into five groups. The first group served as the untreated (normal) control. The second group received NaF at a dose of 600 ppm through drinking water for

Fluoride in low concentration modifies expression and activity of 15 lipoxygenase in human PBMC differentiated monocyte/macrophage
Epidemiological and experimental evidences demonstrate positive correlation between environmental and occupational fluoride exposure and risk to various cardio-respiratory disorders. Therefore we decided to examine the effect of fluorides on activity and expression of 15LOX enzyme which is implicated in biosynthesis of inflammatory mediators. Expression of 15LOX-1 and -2 enzymes mRNA

Buffalo (Bubalus bubalis) epiphyseal proteins give protection from arsenic and fluoride-induced adverse changes in acetylcholinesterase activity in rats
The objective of this study was to determine the effect of fluoride (F) and arsenic (As) on the activity of acetylcholinesterase (AChE), a critically important nervous system enzyme, and to test the protective role of buffalo epiphyseal (pineal) proteins (BEP) in rats. Arsenic (20 mg/kg BW, intraperitoneally) and F (150

Comparative proteomics analysis of cardiac muscle samples from pufferfish Takifugu rubripes exposed to excessive fluoride: initial molecular response to fluorosis
Comparative proteomics was performed to identify proteins in the cardiac muscle of Takifugu rubripes in initial response to excessive fluoride. Sixteen fish were randomly divided into a control group and an experimental group. The control group was raised in softwater alone (F(-) = 0.4 mg/L), and the experimental group was

Effects of fluoride and aluminum exposure to dams prior to and during gestation on mineral compositions of bone and selected soft tissues of female mice dams and pups.
Sixty-four CD-1 female mice were assigned to onez of four water treatment groups: Control (distilled, deionized water) (C); Fluoride (50 ppm F as NaF) (F); Aluminum (100 ppm Al as AlCl3) (Al); and Al & F (50 ppm F & 100 ppm Al) (AlF). One-half of the animals in each

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 & 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

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
