Role of oxidative stress-mediated cell death and signaling pathways in experimental fluorosis.

Introduction Fluorine is one of the most reactive elements with high electronegativity and the second-highest electron affinity. It has an oxidation number of -1 and exists as either inorganic fluorides or organofluorine compounds [1,2]. F- exposure in humans occurs majorly from consuming water contaminated by F- from various natural and anthropogenic sources such as volcanic eruptions, mining residues, industrial effluents, phosphorus fertilizers, and certain domestic activities [3,4].

Further development of mathematical description for combined toxicity: A case study of lead–fluoride combination.

Highlights Rats were exposed during 6 weeks to repeated i.p. injections of lead acetate, sodium fluoride or both in doses 0.05 LD50. The development of intoxication was estimated quantitatively with 54 functional, biochemical and morphometric indices. For mathematical description of effects a response surface regression model containing linear and cross terms was used. 10 types of combined action were found thus confirming the result of the similar study on Pb and Cd.
