    AIM: To investigate whether Nimodipine (N) and Nigella sativa (NS) oil have protective, antioxidant effects in brain injury caused by experimental head trauma. MATERIAL and METHODS: Fifty albino Wistar rats were randomly divided into 5 groups that underwent experimental head trauma. Oxidative parameters were compared in the serum and brain tissue of the different groups. In addition, apoptosis and caspase-3 immunoreactivity were evaluated by histopathological examination. RESULTS: Serum total antioxidant status (TAS) levels were significantly increased in N and N+NS groups when compared with controls (p=0.001, p<0.01). Tissue TAS levels were significantly higher in the NS and N+NS groups compared to controls (p=0.001, p<0.01). Total oxidant status levels in the brain tissue were significantly higher in the NS group than in the control group (p=0.021). CONCLUSION: N and NS were shown to significantly reduce the occurrence of oxidative stress in secondary brain injury due to head trauma. We also found that apoptosis levels decreased in response to N, NS and N+NS treatments after head trauma.

    An Evaluation of the Quality of Sleep Before and After Surgical Treatment of Patients with Cervical Disc Herniation
    (Korean Neurosurgical Soc, 2018) Ogden, Mustafa; Akgul, Mehmet Huseyin; Yuksel, Ulas; Bakar, Bulent; Kamasak, Kagan; Ozveren, Mehmet Faik
    Objective : It has been reported in recent studies that 50-80% of patients with cervical disc hernia have concomitant sleep disorders. The aim of this study was to evaluate the quality of sleep before and after surgical treatment in patients with cervical disc hernia and to assess the effects on treatment. Methods : The study included 32 patients performed discectomy and fusion with an intervertebral cage through the right anterior cervical approach. Oswestry Disability Index (ODI), Visual Analog Scale (VAS) and Pittsburgh Sleep Quality Index (PSQI) were applied to all patients preoperatively and at one month postoperatively. Results : The postoperative PSQI total points and all the PSQI subscale points, the ODI and VAS scores were significantly reduced compared to the preoperative values. A positive correlation was determined between the preoperative ODI points and the PSQI total points and sleep duration, sleep latency and daytime functional loss subscale points. A positive correlation was also found between preoperative ODI points and VAS points. A positive correlation was determined between the preoperative VAS points and and the PSQI total points and sleep duration, and sleep latency subscale points. A negative correlation was determined between the postoperative ODI and the daytime functional loss subscale points. Conclusion : The results of the study showed that in patients with cervical disc hernia, sleep quality and daytime functionality were negatively affected by severity of pain that limited daily activities. Bringing the pain under control with surgical treatment was observed to increase sleep quality. It can be concluded that when planning treatment for these patients, it should be taken into consideration that there could be a sleep disorder in addition to the complaints and symptoms such as pain, hypoestesia and loss of strength.
