Protein Fractions of the Blood Plasma and Dental-Pulp Fluid of the Dog

¹ School of Dentistry and Division of Basic Health Sciences Emory University, Atlanta, Georgia

Pulp fluid obtained from the dog's tooth was shown by electrophoresis to contain the same protein fractions as the blood plasma.

There was but little difference in the relative amounts of the various fractions in the two fluids; however, as the protein content of the plasma was much higher than in the pulp fluid, the absolute amount of the protein fractions was also much higher than in the pulp fluid.

It was suggested that the dental-pulp fluid may be regarded as a capillary transudate.

The data obtained in these experiments lend support to the conclusion deduced from comparative analyses of lymph and blood plasma that globulin escapes more readily from the capillaries than albumin.
