The aim of this study was to investigate the effects of cinnamon bark essential oil (CBO) on analgesia, motor activity, balance, and coordination in rats with sciatic nerve damage.
Rats were divided into three groups as simply randomized. The right sciatic nerve (RSN) of the Sham group was explored. Only vehicle solution was applied for 28 days. The RSN of the sciatic nerve injury (SNI) group was explored. Damage was created by unilateral clamping, and vehicle solution was applied for 28 days. The RSN of the sciatic nerve injury+cinnamon bark essential oil (SNI+CBO) group was explored. SNI was created by unilateral clamping and CBO was applied for 28 days. In the experiment study, motor activity, balance, and coordination measurements were made with rotarod and accelerod tests. A hot plate test was performed for analgesia measurements. Histopathology studies were carried out with the sciatic nerve tissues.
In the rotarod test, there was a statistically significant difference between the SNI group and the SNI+CBO group (p<0.05). According to the accelerod test findings, there was a statistically significant difference between the SNI group with the Sham and SNI+CBO groups. In the hot plate test, there was a statistically significant difference between the SNI group with the Sham and SNI+CBO groups (p<0.05). In comparison to the Sham group and the SNI group, the SNI+CBO group was shown to have the greatest expression level of vimentin.
We have concluded that CBO can be used as an adjuvant treatment in cases of SNI, increased pain, nociception, impaired balance, motor activity, and coordination. Our results will be supported by further studies.
本研究旨在探讨肉桂皮精油(CBO)对坐骨神经损伤大鼠的镇痛、运动活动、平衡和协调的影响。
大鼠随机分为三组。假手术组(Sham 组)仅探查右侧坐骨神经(RSN)。28 天内仅给予载体溶液。坐骨神经损伤(SNI)组探查右侧坐骨神经(RSN)。通过单侧夹闭造成损伤,并给予载体溶液 28 天。坐骨神经损伤+肉桂皮精油(SNI+CBO)组探查右侧坐骨神经(RSN)。通过单侧夹闭造成损伤,并给予肉桂皮精油 28 天。在实验研究中,通过转棒和加速试验测量运动活动、平衡和协调。使用热板试验进行镇痛测量。通过坐骨神经组织进行组织病理学研究。
在转棒试验中,SNI 组与 SNI+CBO 组之间存在统计学显著差异(p<0.05)。根据加速试验结果,SNI 组与 Sham 组和 SNI+CBO 组之间存在统计学显著差异。在热板试验中,SNI 组与 Sham 组和 SNI+CBO 组之间存在统计学显著差异(p<0.05)。与 Sham 组和 SNI 组相比,SNI+CBO 组的波形蛋白表达水平最高。
我们得出结论,CBO 可作为 SNI、疼痛、伤害感受、平衡、运动活动和协调受损的辅助治疗方法。我们的结果将得到进一步研究的支持。
