Objective: The detection rate of traumatic subdural hygroma(TSH) has increased after the development of computed tomography and magnetic resonance imaging. The treatment method and the mechanism of development of the TSH have been investigated, but they are still uncertain. This study is performed to evaluate the effectiveness of subduroperitoneal shunt in traumatic subdural hygroma. Methods: Five hundred thirty six patients were diagnosed as TSH from 1996 to 2002, among them, 55 patients were operated with subduroperitoneal shunt. We analyzed shunt effect on the basis of clinical indetails, including the patient's symptoms at the diagnosis, duration from diagnosis to operation, changes of GCS, hygroma types. We classified the TSH into five types (frontal, frontocoronal, coronal, parietal and cerebellar type) according to the location of the thickest portion of TSH. Results: The patients who have symptoms or signs related to frontal lobe compression (irritability, confusion) or increased intracranial pressure (headache, mental change), had symptomatic recovery rate above 80%. However, the patients who have focal neurological sign (hemiparesis, seizure and rigidity), showed recovery rate below 30%. The improvement rate was very low in the case of the slowly progressing TSH for over 6weeks. We experienced complications such as enlarged ventricle, chronic subdural hematoma, subdural empyema and acute SDH. Conclusion: Subduroperitoneal shunt appears to be effective in traumatic subdural hygroma when the patients who have symptoms or signs related to frontal lobe compression or increased ICP and progressing within 5weeks.

Background: A previous percutaneous coronary intervention (PCI) may affect the outcomes of patients who undergo coronary artery bypass grafting (CABG). The objective of this study was to compare the early in-hospital postoperative outcomes between patients who underwent CABG with or without previous PCI. Methods: The present study included 160 patients who underwent isolated elective on-pump CABG at the department of cardiothoracic surgery, Minia University Hospital from January 2010 to December 2014. Patients who previously underwent PCI (n=38) were compared to patients who did not (n=122). Preoperative, operative, and early in-hospital postoperative data were analyzed. The end points of the study were in-hospital mortality and postoperative major adverse events. Results: Non-significant differences were found between the study groups regarding preoperative demographic data, risk factors, left ventricular ejection fraction, New York Heart Association class, EuroSCORE, the presence of left main disease, reoperation for bleeding, postoperative acute myocardial infarction, a neurological deficit, need for renal dialysis, hospital stay, and in-hospital mortality. The average time from PCI to CABG was $13.9{\pm}5.4$ years. The previous PCI group exhibited a significantly larger proportion of patients who experienced in-hospital major adverse events (15.8% vs. 2.5%, p=0.002). On multivariate analysis, only previous PCI was found to be a significant predictor of major adverse events (odds ratio, 0.16; 95% confidence interval, 0.03 to 0.71; p=0.01). Conclusion: Previous PCI was found to have a significant effect on the incidence of early major adverse events after CABG. Further large-scale and long-term studies are recommended.

The leaves and stems of Dendropanax morbiferus were separated from organic solvents with methanol. The organic solvent fractions were fractionated with dichloromethane, ethyl acetate and butanol according to the systematic fractionation method. Oxidation in the body induces aging, and antioxidant activity has attracted the attention of many people as a preventive component to suppress negative reactions in the body. To investigate the antioxidant activity of Dendropanax morbiferus were subjected to DPPH free radical assay. In addition, acetyl cholinesterase inhibitions were performed for Alzheimer's disease as an aging neurological disease. As a result, it was confirmed that the antioxidant effect of DPPH was generally good in the antioxidant test. The ethyl acetate fractions of Dendropanax morbiferus stems and leaves were $IC_{50}=30{\mu}g/m{\ell}$. Acetyl cholinesterase inhibition experiments were carried out at a concentration of $250{\mu}g/m{\ell}$. Dendropanax morbiferus stems fractions showed dichloromethane fraction of 57.68%, which significantly inhibited the activity of acetyl cholinesterase.

Objectives The purpose of this review is to analyze results of case studies and controlled studies about Carthmi-Flos pharmacopuncture. Based on the review, authors desire to suggest the study model including precise information and evident the effect of Carthmi-Flos pharmacopuncture objectively in treating clinical disorders. Methods We search 44 studies about Carthmi-Flos pharmacopuncture from 6 Korean web databases, using words 'Carthmi-Flos pharmacopuncture' in Korean alphabet. This study had been conducted throughout 1 month (July, 2017). We selected case studies and controlled trials in investigated 44 thesis, excluding experimental research and thesis not using the Carthmi-Flos pharmacopuncture for major treatment. Results We analyze 13 case reports and 7 controlled trials. As a result, Carthmi-Flos Pharmacopuncture was used mostly in musculoskeletal, neurological diseases. But this can be applied to internal diseases. Disorders reported effectively were carpal tunnel syndrome, degenerative knee joint arthritis, posterior neck pain, low back pain, radial nerve palsy, shoulder pain, lumbar compression fracture, alopecia areata, chronic daily headache, duverney fracture, oligomenorrhea, cervical disc herniation, rheumatoid arthritis and cervical headache. Conclusions As we analyzed, Carthmi-Flos pharmacopuncture is specifically effective in musculoskeletal and neurologic diseases. But there are various problems in study design. To design accurately, the study design should include much more specific information. And the result can be more precise by excluding other methods.

This study was designed to investigate the effects of swimming and minocycline on motor function recovery and Bcl-2 expression after spinal cord injury (SCI) in rats. After operation, neurological motor behavior test (BBB scale) on days 1, 4, 7, 10, and 14 were tested. Western blot and immunohistochemical assessment (Bcl-2) were performed on day 14. BBB scale started to show a statistically significant difference on day 7 (p<0.05). On day 14, it showed the most significant (p<0.05) difference. Expression of Bcl-2 increased in all the experimental groups. In particular, the highest expression of Bcl-2 appeared in the swimming and minocycline groups. Based on these results, minocycline and swimming were the most effective factors in the motor behavior function and immunohistochemical assessment of SCI rats.

Botulinum toxin, a neurotoxin, is known to be an inhibitor of cholinergic neuromuscular transmission. Recently, it was reported that the administration of botulinum toxin is effective for the treatment of focal neurological motor disorders such as cervical dystonia, blepharospasm, hemifacial spasm, spasmodic dysphonia, and writer's cramp. Several case studies reported that the botulinum toxin was administered for the treatment of motor tic or vocal tic. It was found that this toxin reduces the frequency and severity of the tic as well as the premonitory urge and symptoms. In our case study, a noticeable decrease of motor tic symptom was observed after an intramuscular injection of 300mg of botulinum toxin in an 18-year-old patient with Tourette's disorder who showed only a little improvement of motor tic and vocal tic symptoms after treatment with antipsychotic drugs for several years. This case is reported in our study and literature survey was undertaken for reviewing similar cases. In our study, an 18-year-old boy diagnosed with Tourette's disorder based on Diagnostic and Statistical Manual of Mental Disorders, fourth edition presented with the following scores : the Clinical Global Impression scale, Yale Global Tic Severity Scale (motor/vocal/severity), Premonitory Urge Score, Korean Attention-Deficit Hyperactivity Disorder Rating scale, and Kovac Depression scale which were performed prior to the treatment were 5, 21/5/50, 100, 17, and 18 points, respectively. Two weeks after the injection of botulinum toxin, the scores were 4, 17/5/40, 50, 16, and 19 points, respectively. Eight weeks after the injection of botulinum toxin, they had become 3, 15/5/30, 25, 16, and 20 points, respectively, which clearly indicates a noticeable decrease of motor tic symptom.

Dexmedetomidine is an ${\alpha}2$-adrenergic receptor agonist that exhibits a protective effect on ischemia-reperfusion injury of the heart, kidney, and other organs. In the present study, we examined the neuroprotective action and potential mechanisms of dexmedetomidine against ischemia-reperfusion induced cerebral injury. Transient focal cerebral ischemia-reperfusion injury was induced in Sprague-Dawley rats by middle cerebral artery occlusion. After the ischemic insult, animals then received intravenous dexmedetomidine of $1{\mu}g/kg$ load dose, followed by $0.05{\mu}g/kg/min$ infusion for 2 h. After 24 h of reperfusion, neurological function, brain edema, and the morphology of the hippocampal CA1 region were evaluated. The levels and mRNA expressions of interleukin-$1{\beta}$, interleukin-6 and tumor nevrosis factor-${\alpha}$ as well as the protein expression of inducible nitric oxide synthase, cyclooxygenase-2, nuclear factor-${\kappa}Bp65$, inhibitor of ${\kappa}B{\alpha}$ and phosphorylated of ${\kappa}B{\alpha}$ in hippocampus were assessed. We found that dexmedetomidine reduced focal cerebral ischemia-reperfusion injury in rats by inhibiting the expression and release of inflammatory cytokines and mediators. Inhibition of the nuclear factor-${\kappa}B$ pathway may be a mechanism underlying the neuroprotective action of dexmedetomidine against focal cerebral I/R injury.

Purpose : To evaluate the effect of global scaling analysis on brain activation for sensory and motor functional MR imaging study. Materials and methods : Four normal subjects without abnormal neurological history were included. Arm extension-flexion movement was used for motor function and 1KHz pure tone stimulation was used for auditory function. Functional magnetic resonance imaging was performed at 3T MRI (GE, Milwaukee, USA) using BOLD-EPI technique and SPM2 was employed for data analysis. On data analysis, the brain activation images were obtained with and without global scaling by fixing other parameters such as motion correction and realignment. Results : The difference in brain activation between no scaling and global scaling was not large in case of right upper extremity movement (p<0.000001). For auditory test, brain activation with global scaling showed larger activation than that of without global scaling (p<0.05). Conclusion : A caution must be taken into account when analyzing functional imaging data with global scaling especially for functional study of small local BOLD signal change.
