Professionals Urge End to Water Fluoridation

Below abstract indicates fluoride damages mito in human kidney cells.

Fluoride ion toxicity in human kidney collecting duct cells.

BACKGROUND: Several halogenated anesthetics induce a urinary
concentrating defect, partly related to fluoride ion toxicity in
collecting duct cells. The aim of this study was to investigate the
effects of fluoride ion in human kidney cells. METHODS: Immortalized
human collecting duct cells were used. In a first set of experiments,
the toxicity threshold concentration was determined by exposing cell
cultures for 24 h to increasing concentrations of fluoride ion in the
medium: 0, 1, 5, and 10 mM. The second set of experiments was a time-
effect study in which cells were exposed to 5 mM fluoride for 2, 6,
and 24 h. Assessment of toxicity was based on several endpoints: cell
number, protein content, (3)H-leucine incorporation in newly
synthesized proteins, extracellularly released lactate dehydrogenase,
Na-K-ATPase pump activity, and electron microscope studies. RESULTS:
After 24 h of exposure, fluoride ion decreased cell number (-23%,
P0.05), total protein content (-30%, P0.05) and increased lactate
dehydrogenase release (+236%, P0.05) at a threshold concentration of
5mM. Fluoride ion also inhibited Na-K- ATPase activity at 5 mM (-58%,
P0.05). Major morphologic alterations of mitochondria, including
crystal formation, were detected from 1 mM fluoride concentration.
Time-effect studies showed that, after only 6 h of exposure at 5 mM,
fluoride decreased cell number (-13%, P0.05), (3)H-leucine
incorporation (-48%, P0.05), and Na-K-ATPase activity (- 20%, P0.05)
and increased lactate dehydrogenase release (+145%, P0.05). Crystal
deposits in mitochondria again were a more sensitive marker of cell
injury, detectable after only 2 h of exposure. CONCLUSIONS: these
results suggest that the mitochondrion is a target of fluoride
toxicity in human collecting duct cells, and its alteration is partly
responsible for the sodium and water disturbances observed in
patients. PMID: 8602675

Below article indicates fluoride renders bunny sperms infertile.

Ultrastructural studies of spermiogenesis in rabbit exposed to chronic
fluoride toxicity.

OBJECTIVE--To address the role of fluoride in causing defects to
spermatids and epididymal spermatozoa. METHODS--Male rabbits were
treated with 10 mg NaF/kg body weight daily for 18 months and
maintained under identical laboratory conditions along with the
control rabbits not given NaF. Testis and epididymis (caput) were
investigated for ultrastructural details of spermatids and
spermatozoa. RESULTS--A wide variety of structural defects were
observed in the flagellum, the acrosome, and the nucleus of the
spermatids and epididymal spermatozoa of fluoride-treated rabbits.
Abnormalities included absence of outer microtubules, complete absence
of axonemes, structural and numeric aberrations of outer dense fibers,
breakdown of the fibrous sheath, and structural defects in the
mitochondria of the middle piece of the flagellum. Detachment and
peeling off of the acrosome from the flat surfaces of the nucleus were
also observed. CONCLUSION--The abnormalities observed render the sperm
nonfunctional and ineffective, and thus there is a possible role of
fluoride in causing infertility. PMID: 7920753

There is much more at http://www.fluoridealert.org about fluoride in
air, fertilizers, how it kills bees, etc.

#1 Nobody drinks tap water any more, certainly not children.

#2 Anybody who drinks tap water has the option of filtering it.

Therefore, Fluoridation of drinking water stopped being an issue some
20 years ago.

Just thought that you might want to know.

Hi John. Rarely do we agree, but here is one time. I saw the nut job
NYCOF on CNN a few years ago. He was, of course, discussing flouride.
He would not allow the advocate speak. AEvery time the advocate
started a sentence, the rude jerk would interupt and cut him off.

The CNN talking head was unable to restrain him.

And, to think he lives near me.

Shudder.

OK, back to not agreeing.
