Introduction
The aim of the present study was to evaluate the effect of oxytocin on the angiogenesis and inflammatory parameters in air pouch model of inflammation.Methods
Inflammation was induced by injection of carrageenan into pouches in male Wistar rats. Oxytocin (4.25, 8.5 and 17 μg) was administered intra pouch at the same time as the carrageenan and then for 2 consecutive days. After 72 h, the pouches fluid was collected to determine exudates volume, interleukin 1-beta (IL-1ß) and vascular endothelial growth factor (VEGF) concentrations. Then, the pouches were dissected out, weighed and the hemoglobin concentration was assessed.Results
All three doses of oxytocin (4.25, 8.5 and 17 μg) significantly decreased volume of exudates (PConclusion
Oxytocin has an anti-inflammatory effect and inhibits cell influx and exudation to the site of the inflammatory response. The anti-angiogenesis effect of oxytocin may be related to the local inhibition of VEGF levels as similarly shown by diclofenac.Keywords:
