In order to reveal the mechanism of the decreased ability of learning and memory induced by chronic fluorosis, nicotinic acetylcholine receptors (nAChRs) and the pathway of extracellular signal regulated protein kinase (ERK1/2) were investigated by using the rats fed with different concentrations of sodium fluoride for 6 months.

The study was conducted to characterize the action of NaF, which had relaxing property in carbachol precontracted isolated bovine bronchus, on airway responsiveness challenged by acetylcholine receptor agonists in rats and asthmatic humans.

Moreover, sodium-fluoride may cause adverse effects on testicular activity (connected to oxidative-stress depending on increased activity of peroxidases and catalases) due to inhibition of 2 androgenesis-regulator enzymes DELTA (5) b-HSD and 17beta-HSD.
At encephalic level, then, high doses of fluorine cause the onset of neurological symptoms and of a decreased spontaneous motor activity due to a reduction in the number of nicotinic acetylcholine receptors.
