The Estimation of Nanogram Levels of Fluoride in Fractions of a Milligram of Tooth Enamel by Means of Liver Esterase

Abstract

SYNOPSIS IN INTERLINGUA

LE ESTIMATION DE NIVELLOS NANOGRAPHIC DE FLUORURO IN FRACTIONES DE UN MILLIGRAMMA DE ADAMANTE DENTAL EFFECTUATE PER MEDIO DE ESTERASE HEPATIC.—Le specimens esseva incubate in le presentia de esterase hepatic e de butyrato ethylic como substrato, e le activitate enzymatic esseva determinate per titration a alcali del acido butyric formate. Le effecto de phosphato de calcium super le activitate enzymatic esseva investigate per le addition de ille sal al controlo (sin fluoruro) e al standards a un nivello equivalente a illo in le incognito ubi illo habeva essite determinate per un analyse de phosphoro. Post correction per referentia al blanco, le activitates enzymatic in le incognito e in le standards esseva convertite in procentages del activitate in le controlo. Le nivello de fluoruro in le incognito esseva alora determinate ab un graphico le qual relationava le procentages del hydrolyse de controlo monstrate per le standard con le logarithmos de lor nivellos de fluoruro.
