The effect of meloxicam and cryopreserved placenta extract on initial inflammatory response - an experimental study.

Abstract

Alteration is the first phase of the inflammatory process triggering the entire cascade of inflammation and causing destructive changes in the affected tissues. Therefore, suppression of inflammation at this point is essential for the success of anti-inflammatory therapy. Previous experimental studies have shown that the combined use of nonsteroidal anti-inflammatory drugs and drugs with pleiotropic mechanisms of action may potentiate their anti-inflammatory properties. The purpose of my work was to characterize the combined effect of cryopreserved placenta extract and meloxicam on the alterative phase of the inflammatory process in a model of aseptic skin and subcutaneous tissue inflammation in rats. Subcutaneous administration of acetic acid and of dextran was found to result in formation of necrotic ulcers in 100% of rats by day 7 of the experiment. The most pronounced antialterative effect (23.9%) on day 7 of the experiment was observed with the combined use of meloxicam and cryopreserved placenta extract - the area of necrotic ulcers was 1.3-fold smaller (p < 0.05) as compared with control rats (without treatment). On day 27 of the experiment, the antialterative effect of combined treatment and prophylactic use of meloxicam and cryopreserved placenta extract was 1.7 times higher than the effect in meloxicam monotherapy group, and 1.2 times higher than that in the placenta cryoextract monotherapy group.
