Investigation of the Effects of Calcıum Channel Blockers with Cigarette Smoke Exposure to Nerve Healing at Peripheral Nerve Injuries

Abstract

Objective: A study was planned to investigate the effect of exposure to cigarette smoke and the effects of calcium channel blockers in experimentally induced sciatic nerve injuries. Material-Method: The sciatic nerve was cut on one side in all the groups, and repair was performed in hour 0. After repair, a single daily dose of 1 ml of 0.9% saline was administered to group 1, 90 days, 30 minutes, cigarette smoke to group 2, 1mg/kg calcium channel blocker to group 3, 90 days, 30 minutes, cigarette smoke and 1mg/kg Calcium channel blocker was given to group 4. Results: At the end of the 12th week, gait analysis at and sciatic function index (SFI), the number of myelinated axons, axon areas and myelin diameters were assessed. There was a significant difference between the measured values of SFI in group 1 and group 3 and 4, and there was a significant difference between group 2 and group 3 and 4 (p <0.05). In addition there was a significant difference between the number of axons in group 2 and group 3 (p <0.05). Conclusion: As a result, after peripheral nerve laceration repair calcium channel blockers have a positive effect on the sciatic function index while cigarette smoke has a negative effect. In addition, according to the sciatic function index the negative effect of cigarette smoke can be resolved with calcium channel blockers. But; these data are not supported by the number of axon, axon area, and the myelin diameter
