title: Effect of fluoride on alpha-chymotrypsin.
abstract: Sodium fluoride has been demonstrated by spectrophotometric experiment to have an inhibitory effect on the hydrolyzing action of alpha-chymotrypsin. Sodium fluoride in moderate therapeutic dosage possibly can retard or completely inhibit the activity of bone-resorbing enzymes in the otospongiotic focus, thus retarding or arresting active expansion of a focus and resulting in stabilizing or arresting the progression of sensorineural hearing loss that is associated with otospongiosis.
