Effects of chronic fluorosis on thyroxine, triiodothyronine, and protein-bound iodine in cows

In this study, the serum levels of thyroxine (T4), triiodothyronine (T3), and protein-bound iodine (PBI) in the control cows were in the normal range of healthy cows, but they were significantly lower (p<0.05) in the fluorotic cows. These findings are consistent with the results of research with sheep, calves, cattle, and rats. . . . On the other hand, Choubisa reported that none of a group of fluorotic domestic animals exhibited any apparent evidence of hypothyroidism, stunted growt

Does fluoride ingestion affect developing immune system cells?

Introduction Generally about half of the fluoride absorbed is deposited in bone. It was found in Finland (1) that the fluoridation of a water supply greatly increased the rate of fluoride accumulation in bone, from a mean of 11 ppm annually in low-fluoride areas to a mean of 44 ppm in the fluoridated people. In a warmer climate with a very 'soft' water supply the rate of increase may be more rapid. In a pilot study in Melbourne (2) the annual fluoride concentration increase in alveolar bone in

Is the ingestion of fluoride an immunosuppressive practice?

Introduction In 1987, Moolenburgh (1) stated: 'I am absolutely convinced that fluoride is an immune suppressive substance.' He came to that conclusion following double-blind clinical tests which showed that there were many adverse reactions resulting from drinking fluoridated water. In 1987, Sutton (2) advanced the hypothesis that, as a result of the normal resorption of bone containing a high concentration of fluoride (which forms in those who habitually drink fluoridated water) (3), the rele
