Abstract
The phenotype frequency distributions of several classical blood genetic markers and dermatoglyphic characters were analyzed in workers of Siberian aluminum plants who had occupational fluorosis. Comparison with healthy workers revealed significant differences in frequencies of several markers. Phenotypes B (AB0), D (Rh), MN (MN), P1 (P), Le a (Lewis), Gc 2-1, Cx (on both hands), Th/I+ (on the left hand), C3, and C4 (HLA) were associated with higher risk of occupational fluorosis.

Liver proteome of mice with different genetic susceptibilities to the effects of fluoride
OBJECTIVE: In this study, we investigated the differential pattern of protein expression in the liver of these mice to provide insights on why they have different responses to F. MATERIAL AND METHODS: Weanling male A/J and 129P3/J mice (n=10 from each strain) were pared and housed in metabolic cages with ad

[Genetic markers of occupational susceptibility to fluorosis].
To determine markers showing propensity to occupational fluorosis, the authors studied prevalence of ABO, Rh, MN, ABH and Lewis phenotypes, systemic rhesus haplotypes in 229 workers engaged into aluminum production. Propensity to occupational fluorosis was marked by P (+), O (ABO) phenotypes. P (-) phenotype appeared to be a marker

[Genetic factors predisposing to occupational fluorosis].
Having analyzed a total amount of all systems, the authors specified the most important genetic markers predisposing to chronic flour intoxication: the patients demonstrated higher frequency of ACP1*A and PGM1*1-alleles, phenotypes of acid phosphatase AA, of phosphoglucomutase 1+1+ and 2+2+, of dry cerumen consistence--d. The results could help to improve

The genetic influence on bone susceptibility to fluoride
INTRODUCTION: The influence of genetic background on bone architecture and mechanical properties is well established. Nevertheless, to date, only few animal studies explore an underlying genetic basis for extrinsic factors effect such as fluoride effect on bone metabolism. MATERIALS AND METHODS: This study assessed the effect of increasing fluoride doses (0

Toxicology and Carcinogenesis Studies of Sodium Fluoride in F344/N Rats and B6C3F1 Mice (Drinking Water Studies)
CASRN: 7681-49-4 Chemical Formula: NaF Molecular Weight: 41.99 Report Date: December 1990 Sodium fluoride is a white, crystalline, water-soluble powder used in municipal water fluoridation systems, in various dental products, and in a variety of industrial applications. Toxicology and carcinogenesis studies were conducted with F344/N rats and B6C3F1 mice of each sex by incorporating

Factors which increase the risk for skeletal fluorosis
The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.

Annapolis: Water Fluoridation Linked to Death of Dialysis Patient
EVENING CAPITAL (Annapolis, Maryland) November 29, 1979 Fluoride Linked to Death by Mary Ann Kryzankowicz Staff Writer Fluoride poisoning has been definitely linked to the death of a 65-year-old kidney dialysis patient who became ill during a blood cleaning process Nov 11. State Medical Examiner Dr. (illegible) Guard has ruled that Lawrence Blake, 65, of Arundel

Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence
A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.

Dental Fluorosis & Enamel Hypoplasia in Children with Kidney Disease
Children with kidney disease are known to have high levels of fluoride in their blood and to be at risk for disfiguring tooth defects. Research suggests that high levels of fluoride in blood, which can cause the tooth defect known as dental fluorosis, can contribute to the defects that occur

Unheeded Warnings: Government Health Authorities Ignore Fluoride Risk for Kidney Patients
Despite the well known fact that individuals with kidney disease are at much higher risk of fluoride toxicity than the general population, there has yet to be any attempt in the United States, or any other country that practices mass-scale water fluoridation to determine the prevalence of fluoride-related effects (e.g.,
