Effect of Umbelliprenin on behavioral symptoms of neuropathic pain in chronic constriction injury model (CCI) of neuropathy in adult male rats

Background and Purpose: Chronic neuropathic pain caused by damage or disturbance of the functioning of the somatosensory system are one of the major health problems and many people suffer from such diseases. The aim of this study was to investigate the effect of Umbelliprenin (UMB) on the symptoms of neuropathic pain in chronic constriction injury model (CCI) of neuropathy in adult male rats. 24Wistar rats (250±20g) were randomly divided into 3 groups: sham, CCI and CCI+UMB (100μg/rat) groups. UMB was injected intrathecaly one day before surgery, and 3 days after surgery. Von Frey and Hot-Plate tests were performed one day before surgery and on days 2, 4, 7, 10 and 14 after surgery. The results were reported as mean and SEM (P
