ABSTRACT
OBJECTIVE: 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. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
