Phagocytic Function of Peripheral Blood, Gingival Crevicular Fluid and Salivary Polymorphonuclear Leukocytes.

Gingival Crevicular Fluid Biomarkers

Material and Method: Thirty patients were allocated into 3 groups: 10 were treated with scaling and root planing (SRP) only; 10 were treated with SRP and received adjunctive local metronidazole; 10 were treated with SRP and received adjunctive systemic metronidazole. Periodontal clinical parameters including plaque index, sulcus bleeding index, probing depth and relative attachment level were r...

Lactoferrin in Gingival Crevicular Fluid and Peripheral Blood during Experimental Gingivitis

OBJECTIVES Lactoferrin (LF) is an iron binding protein and stored in the specific granules of granulocytes. It is released by degranulation following granulocyte activation. A positive correlation was previously reported between periodontitis and LF titers of gingival crevicular fluid (GCF) and blood. The purpose of this study was to examine alterations of GCF and blood levels of LF (LF-GCF and...

Comparative morphology, respiration, and phagocytic function of leukocytes from blood and joint fluid in rheumatoid arthritis.

RNA and protein synthesis in human peripheral blood polymorphonuclear leukocytes

Polymorphonuclear leukocytes purified from human peripheral blood synthesized RNA and proteins when placed in cell culture. Autoradiography of the cultured cells revealed that a majority of mature PMNs were engaged in macromolecule synthesis, and an analysis of newly synthesized proteins by SDS-polyacrylamide gel electrophoresis showed that many different polypeptide chains were synthesized by ...

Evidence for polymorphonuclear leukocyte collagenase and 92-kilodalton gelatinase in gingival crevicular fluid.

Analysis of inflammatory exudate collected from sites of experimental periodontitis in cynomolgus monkeys has revealed the presence of collagenase and a 92-kDa gelatinase that comigrated after electrophoresis with the 92-kDa gelatinase released from polymorphonuclear leukocytes. Since neutralizing antibodies to fibroblast collagenase had no effect on the collagenase activity and bacterial colla...
