[Active forms of oxygen and nitrogen in blood cells of patients with rheumatoid arthritis: effect of laser therapy].

Infrared pulse laser therapy was studied for its impact on the production of active forms of oxygen and nitrogen by neutrophils from patients with rheumatoid arthritis (RA). The authors determined the non-activated and PMA-activated production of superoxide anion-radical, peroxynitrite, peripheral neurophilic NAD.PH-oxidase and superoxide dismutase activities, and the red blood cell concentrations of reduced glutathione.

[Effects of low-intensity infrared impulse laser therapy on inflammation activity markers in patients with rheumatoid arthritis].

Aim: To evaluate effects of low-intensity infrared impulse laser therapy (IRILT) on concentration of immunity activation [not readable: see text] (soluble receptors of TNF-alpha and neopterin) and indicator of the inflammation activity (concentration of C-reactive protein) in patients with rheumatoid arthritis (RA).

Materials And Methods: Enzyme immunoassay, radioimmunoassay, enzyme immunoassay and radial immunodiffusion were used to measure soluble receptors of TNF-alpha, neopterin and C-reactive protein in 38 females with verified RA receiving IRILT or sham procedures.

Results: IRILT induced lowering of neopterin, TNF-alpha soluble receptors (p < 0.

[Soluble adhesion molecules (P-selectin, ICAM-1 and ICAM-3) in rheumatoid arthritis].

Aim: Investigation of serum levels and clinical role of soluble intercellular molecules of adhesion (pICAM-1, PICAM-3 and pP-selectin) in rheumatoid arthritis (RA).

Materials And Methods: Enzyme immunoassay with Bender MedSystem kits (Austria) was employed to measure serum concentration of soluble intercellular molecules of adhesion in 36 RA patients.

Results: Elevated levels of serum pICAM-1, pICAM-3 and pP-selectin were registered in 74.
