Unstimulated Whole Saliva

The aim of this work was to evaluate of hydrolytic activity of whole saliva using chitosan ascorbate as a substrate. In this aim, the concentrations of N-acetyl-D-glucosamine were determined in saliva before addition of chitosan ascorbate, directly after addition and during incubation with chitosan ascorbate by 20 hrs. In this in vitro study were used sterile chitosan ascorbate in the form of powder. Chitosan was obtained from krill chitin. The ratio of ascorbic acid to chitosan was 1:1. The unstimulated whole saliva showed the hydrolytic activity in the presence of the chitosan ascorbate as a substrate.

Vitro Effect

It has already been shown that, in addition to ascorbic acid, 5-hydroxytryptamine and several other 5-hydroxyindole compounds affect the oxidative activity of ceruloplasmin and serum oxidase. Therefore, an in vitro study of the effect of several other normal metabolites and drugs on this enzyme system was undertaken. It was found that the compounds which affect this reaction fall into two classes. One group (cysteine, penicillamine and ascorbic acid) reacts with the oxidized form of the substrate reducing it back into the original compound, thereby producing a lag period in the reaction. The other group (DOPA and iproniazid) inhibits the reaction, probably by competing with the substrate molecules for the enzyme site. Submitted on November 17, 1958
