Abstract
RESULTS: This work presents mechanisms by which interaction of fluoride ions with enzymes can take place. The effects of fluoride on enzymes participating in cellular metabolic pathways, like energy formation and carbohydrate and lipid turnover, are discussed. A list of enzymes which are inhibited or activated in vivo and in vitro by fluoride ions is provided, together with information on species and organs of origin, fluoride concentration, and extent of inhibition or activation.

In vivo influence of sodium fluoride on sperm chemotaxis in male mice
Reproductive process covers lots of procedures, including capacitation, hyperactivation, chemotaxis and the acrosome reaction. Each plays an important role in the success of fertilization. Although multiple studies have reported the toxic effects of fluoride on the male reproduction, the effect of fluoride on sperm chemotaxis is little known. This study

Lipid peroxidation and antioxidant enzyme status of adult males with skeletal fluorosis in Andhra Pradesh, India.
Blood samples from 24 adult males, age 25 to 40, with endemic skeletal fluorosis, living in the Vaillapally village of the Nalgonda district, Andhra Pradesh, India, were examined and compared with samples from 15 matched controls for their antioxidant enzyme activity and lipid peroxidation. Elevated malondialdehyde (MDA) levels indicated an

Effect of fluorozis [sic] on the erythrocyte antioxidant enzyme activity levels
While the flourine level of (drinking) water was higher than normal ranges in the center of Isparta region before 1995 year, this problematic situation is solved in later years. (However) the individuals who are staying in Yenice district are still expose to high levels of fluorine because of the usage

Diverse effects of fluoride on NA+ and K+ transport across the rat erythrocyte membrane.
The cellular effects of fluoride (as F – from NaF) on Na + and K + transport across the rat erythrocyte membrane were investigated using 22 Na as a tracer and nonradioactive Rb + as a K + congener. Exposure of rat erythrocytes to 20 mM NaF for 30–120 min

Effects of fluoride on cells and tissues in culture: a review.
Various authors have studied the effect of fluoride ion upon mammalian cells using many different biological end-points, of:which inhibition of the function of specific cellular enzymes, survival of cell reproductive capacity, production of abnormalities of cell division and alteration in the rate of cell proliferation are a representative sample.
