Sodium fluoride (NaF) is a(n) _____? ABSTRACT As a medical treatment for otospongiosis-otosclerosis, sodium fluoride influences the underlying bony changes in the labyrinth so as to arrest or prevent the onset of hearing loss. Yet this conversion can be inhibited by the introduction of sodium fluoride as it is an inhibitor of the enzyme “enolase” an enzyme necessary for glycolysis(2). In the yeast an enzyme enolase catalyzes the conversion of phosphoglycerate into phosphoenol pyruvate. This reaction is dependent on Mg ions and is inhibited by flouroide ions (sodium fluoride, NaF, precipitates Mg ions and thus inhibits the pathway.) Sodium fluoride is an enzyme inhibitor and reduces osteoclastic bone resorption and, if the dosage is more than 60 mg a day, may rebuild pseudohaversian bone. In 1988, Uchida et al. The failure of NaF to properly control glycolysis decreases plasma glucose concentrations. In order to perform this task, sodium fluoride (NaF) exerting its action on enolase, an enzyme which catalysed a down-stream step of glycolysis, played a fundamental role in the past. Sodium fluoride. As a medical treatment for otospongiosis-otosclerosis, sodium fluoride influences the underlying bony changes in the labyrinth so as to arrest or prevent the onset of hearing loss. The high affinity of fluoride toward these elements can impair enzyme activity,27 Macrophage Sodium fluoride probably promotes oxidative stress in macrophages, which is manifested by a strong Reactive oxygen species increase in ROS synthesis and a decrease in ATP. .O��� � [Content_Types].xml �(� �Yێ�0}��@�V�!m��*�>����J�� &�[�-�I7_s d�dľ��03�pl�wOy@i&�*��y OD��v�|�2� m(Oi&8��#��n�����(Av4׫pg��@�Nv�S ����ScOՖH���[ ����$��ff��z��P,���*��v"�!
