STUDIES OF HUMAN MIXED SALIVA

Studies of Human Mixed Saliva

In 1835, Donne (1) reported that although he found the saliva normally alkaline to litmus, he had found it acid in many diseases, including encephalitis. In 1844, Wright (2) attempted to elaborate a diagnostic system of salivary analysis. About the same time, Simon (3) wrote at length on “morbid saliva” as distinct from “normal.” Among other studies of a similar character were those of Binet (4...

Erythropoietic Factor in Human Mixed Saliva

Studies on the Antibacterial Factors of Human Saliva.

In previous studies it was found that the growth of 110 of 169 strains of bacteria tested was prevented by human saliva (Bibby, Clough and Hine, 1938). This effect was more marked against some types of organisms than against others, those most affected being bacilli and cocci isolated from air and water; those least affected, organisms isolated from the mouth. Differences occurred in the inhibi...

High resolution proton nuclear magnetic resonance studies of human saliva.

High resolution proton Nuclear Magnetic Resonance (NMR) can be used for multicomponent analysis of low molecular weight compounds in small amounts of intact biological materials and biological fluids. It can provide useful qualitative and quantitative biochemical information without the necessity of any pretreatment such as extraction, separation, or purification. The NMR spectra of serum, plas...

Rheological properties of human saliva.

From measurements with a Couette-type viscometer provided with a guard ring it was shown that at the saliva-air interface a protein layer is adsorbed. Measurements of the surface shear modulus of this layer on saliva of 7 healthy subjects were performed at a frequency of about 70 Hz and a temperature of 25 degrees C. For a surface age of about 1.5 h the surface shear modulus and the surface vis...
