Breakdown of Various Serum Proteins by Periodontal Bacteria

Periodontal Bacteria and Epithelial Cell Interactions: Role of Bacterial Proteins

Editorial Periodontal diseases are a group of chronic multifactorial infections that initiate destruction of periodontium, the tissues that surround and support the teeth. The main etiological agent of periodontitis is the microbial dental plaque. Etiologically most important periodontal microorganisms are gram-negative, facultative or obligatory anaerobic rods; the strongest association betwee...

Effects of various serum proteins on quantification of fructosamine.

We determined fructosamine concentrations with the CentrifiChem 600 centrifugal analyzer and the Hitachi 737 discrete analyzer. Reference intervals agreed with the most recently published results, and values in fasting patients were significantly correlated with glycated hemoglobin, plasma glucose, albumin, beta- and gamma-globulins, IgG, IgA, IgM, and total protein. Partial correlation analysi...

L-asparaginase production by various bacteria.

Of 123 species of bacteria surveyed for L-asparaginase synthesis, Erwinia aroideae NRRL B-138 provided the highest yields.

Distribution of the serum proteins of Syrian hamster as revealed by Starch gel electrophoresis

Differentiating various abnormalities of thyroxin binding to serum proteins by radioelectrophoresis of thyroxin and immunoassay of binding proteins.

Using the simple method of protein analysis described here, we could identify thyroxin (T4)-binding-protein abnormalities in euthyroid patients with hyperthyroxinemia or hypothyroxinemia. Serum incubated with [125I]thyroxin was analyzed by agarose gel electrophoresis, with bromphenol blue staining of protein. The relative distribution of radioactive T4 was determined for each binding protein--t...
