Objective: The aim of this study was to report the effectiveness of traditional Korean medicine treatment with rehabilitation exercise on a chronic intracerebral hemorrhage patient with a severe gait disturbance. Method: The patient was treated with Korean herbal medicine (Gami-sibjeondaebo-tang) along with acupuncture, moxibustion, and rehabilitation exercise. The treatment effect was evaluated through the Manual Muscle Test (MMT) and the Korean version of the Modified Barthel Index (K-MBI). The gait of the patient was evaluated by Functional Ambulatory Category (FAC) and the Timed Up and Go (TUG) test. The spatiotemporal parameters were evaluated by a walkway system (GAITRite(R) system) and gait symmetry was evaluated by Symmetry Criterion (SC). Results: After 111 days of traditional Korean medicine treatment, the spatiotemporal parameters and symmetry of the patient's gait improved. Conclusion: This study suggested that traditional Korean medicine treatment with rehabilitation exercise could be effective for gait disturbance in patients with chronic intracerebral hemorrhage.

In Korean medicine, the "five viscera" theory develops into the theory of homeostasis, in which the dynamic equilibrium state of the yin yang and five elements in the body maintain the balance of the physiological functions. The "five viscera" of the "five elements" can also be referred to as the "functional system," a conceptual system that includes all functional interactions mediated by the organ as well as the organ itself. Nowadays, the structure and function of the organs and tissues in the body are being re-examined, and there is now enough evidence that organs, structures, and their functions that belong to the same "element" are all connected in terms of energy metabolism. The functional system of the "kidney" includes the kidney itself, as well as other components that belong to "water" of the five elements such as bladder, bone, ear, essence, memory, and fear. The authors will discuss the latest findings in science and medicine to expand the understanding of the "Kidney" functional system to the level of molecular physiology.

Background: Transcranial magnetic stimulation (TMS) is a non-invasive diagnostic method particularly suited to investigation the long motor tracts. The clinical value of TMS in most spinal cord diseases has still to be made. Diagnostic value of magnetic motor evoked potential (MEP) parameters in intramedullary spinal cord lesions was investigated. Methods: MEP elicited by TMS was recorded in 57 patients with clinically and radiologically defined intramedullary myelopathy. Twenty five patients with cervical myelopathy (CM) and 32 thoracic myelopathy (TM) were included. Recordings were performed during resting and minimal voluntary contraction at both abductor pollicis brevis (APB) and tibialis anterior (TA) muscles. Stimulation threshold(ST), amplitude, and central motor conduction time (CCT) were measured at resting and facilitated conditions. CCT was calculated by two means; central motor latency (CML)-M using magnetic transcranial and root stimulation, and CML-F using electrical F-wave study. The results were compared between patient groups and 10 normal control group. Results: Facilitated mean ST recorded at TA was elevated in both CM and TM compared with control group. Resting mean CML-M at TA was significantly prolonged in both CM and TM, and CML-M was absent or delayed in 37.1% of CM and 8% of TM at APB with facilitation. Facilitated mean MEP amplitude at ABP was lower in CM than in TM, while MEP/M ratios were not different significantly between groups. Conclusions: Magnetic motor evoked potential has diagnostic value in intramedullary myelopathy and localizing value in differentiating between CM and TM by recording at APB and TA. It is a noninvasive way to investigate the functional status of motor tracts of spinal cord.

The purpose of this study was to verify whether Mediterranean diet, which proved to have a significant effect on preventing dementia for people aged 65 or older, could be well modified to be a Korean-style Mediterranean diet. This study was performed as a randomized-controlled trial for 6 weeks. Functional physical changes, cognitive scores, depression scores and dietary changes were all assessed. The walking speed (P<0.001) and the cognitive scores were statistically improved in only the experimental group (P<0.001), and the depression scores were also significantly improved in only the experimental group (P<0.01). The dietary intake showed a 30% improvement for consuming more than 7 cups per day of vegetables and fruits. When the participants were contacted four months after the end of the study, 90% of them said that the Korean-style Mediterranean diet was feasible and 100% said the nutrition interventions helped them maintain the diet during their daily lives. The results suggest that although the Mediterranean diet can be difficult to apply, any limitations of this healthy diet can be overcome.

Objective: This study reports on the effectiveness of Korean medicine treatment in a patient with intracerebral hemorrhages with symptoms of hemiplegia, personality change, and aphasia. Case presentation: The patient was treated using Korean medicine, including Jayumkeonbi-tang with deer antler as herbal medicine, acupuncture, moxibustion, and a limb activation exercise. To evaluate the effect on clinical symptoms, a manual muscle test, the Modified Functional Ambulation Classification, and the Korean version of the Modified Barthel Index were used. After 84 days of treatment, the MMT grade of the right upper and lower limbs improved from Gr. 2+/2- to Gr. 4/3~4 on average, and personality change and aphasia were gone. Conclusion: A complex treatment that includes Jaeumkunbi-tang, acupuncture, moxibustion, and limb activation exercises can be effective following an intracerebral hemorrhage resulting in hemiplegia and personality change. However, more research is needed.

Objective : We retrospectively evaluated the prognostic factors that can influence long-term survival in patients who suffered acute large cerebral infarction. Methods : Between June 2003 and October 2008, a total of 178 patients were diagnosed with a large cerebral infarction, and, among them, 122 patients were alive one month after the onset of stroke. We investigated the multiple factors that might have influenced the life expectancies of these 122 patients. Results : The mean age of the patients was $70{\pm}13.4$ years and the mean survival was $41.7{\pm}2.8$ months. The mean survival of the poor functional outcome group ($mRS{\geq}4$) was $33.9{\pm}3.3$ months, whereas that of the good functional outcome group ($mRS{\leq}3$) was $58.6{\pm}2.6$ months (p value=0.000). The mean survival of the older patients (270 years) was $29.7{\pm}3.4$ months, whereas that of the younger patients (<70 years) was much better as $58.9{\pm}3.2$ months (p value=0.000). Involvement of ACA or PCA territory in MCA infarction is also a poor prognostic factor (p value=0.021). But, other factors that are also known as significant predictors of poor survival (male gender, hypertension, heart failure, atrial fibrillation, diabetes mellitus, a previous history of stroke, smoking, and dyslipidemia) did not significantly influence the mean survival time in the current study. Conclusion : Age (older versus younger than 70 years old) and functional outcome at one month could be critical prognostic factors for survival after acute large cerebral infarction. Involvement of ACA or PCA territory is also an important poor prognostic factor in patients with MCA territorial infarction.

Human bone marrow mesenchymal stem cells (hBM-MSCs) represent a potentially valuable cell type for clinical therapeutic applications. The present study was designed to evaluate the effect of long-term culturing (up to $10^{th}$ passages) of hBM-MSCs from eight individual amyotrophic lateral sclerosis (ALS) patients, focusing on functional ion channels. All hBM-MSCs contain several MSCs markers with no significant differences, whereas the distribution of functional ion channels was shown to be different between cells. Four types of $K^+$ currents, including noise-like $Ca^{+2}$-activated $K^+$ current ($IK_{Ca}$), a transient outward $K^+$ current ($I_{to}$), a delayed rectifier $K^+$ current ($IK_{DR}$), and an inward-rectifier $K^+$ current ($K_{ir}$) were heterogeneously present in these cells, and a TTX-sensitive $Na^+$ current ($I_{Na,TTX}$) was also recorded. In the RT-PCR analysis, Kv1.1,, heag1, Kv4.2, Kir2.1, MaxiK, and hNE-Na were detected. In particular, ($I_{Na,TTX}$) showed a significant passage-dependent increase. This is the first report showing that functional ion channel profiling depend on the cellular passage of hBM-MSCs.

Background: Gut microbiota influence the central nervous system through gut-brain-axis. They also affect the neurological disorders. Gut microbiota differs in patients with Alzheimer's disease (AD), as a potential factor that leads to progression of AD. Oral intake of Korean Red Ginseng (KRG) improves the cognitive functions. Therefore, it can be proposed that KRG affect the microbiota on the gut-brain-axis to the brain. Methods: Tg2576 were used for the experimental model of AD. They were divided into four groups: wild type (n = 6), AD mice (n = 6), AD mice with 30 mg/kg/day (n = 6) or 100 mg/kg/day (n = 6) of KRG. Following two weeks, changes in gut microbiota were analyzed by Illumina HiSeq4000 platform 16S gene sequencing. Microglial activation were evaluated by quantitative Western blot analyses of Iba-1 protein. Claudin-5, occludin, laminin and CD13 assay were conducted for Blood-brain barrier (BBB) integrity. Amyloid beta (Aβ) accumulation demonstrated through Aβ 42/40 ratio was accessed by ELISA, and cognition were monitored by Novel object location test. Results: KRG improved the cognitive behavior of mice (30 mg/kg/day p < 0.05; 100 mg/kg/day p < 0.01), and decreased Aβ 42/40 ratio (p < 0.01) indicating reduced Aβ accumulation. Increased Iba-1 (p < 0.001) for reduced microglial activation, and upregulation of Claudin-5 (p < 0.05) for decreased BBB permeability were shown. In particular, diversity of gut microbiota was altered (30 mg/kg/day q-value<0.05), showing increased population of Lactobacillus species. (30 mg/kg/day 411%; 100 mg/kg/day 1040%). Conclusions: KRG administration showed the Lactobacillus dominance in the gut microbiota. Improvement of AD pathology by KRG can be medicated through gut-brain axis in mice model of AD.

Background and Purpose: The effects of high-intensity interval training (HIIT) interventions on functional brain changes in older adults remain unclear. This preliminary study aimed to explore the effect of physical exercise intervention (PEI), including HIIT, on cognitive function, physical performance, and electroencephalogram patterns in Korean elderly people. Methods: We enrolled six non-dementia participants aged >65 years from a community health center. PEI was conducted at the community health center for 4 weeks, three times/week, and 50 min/day. PEI, including HIIT, involved aerobic exercise, resistance training (muscle strength), flexibility, and balance. Wilcoxon signed rank test was used for data analysis. Results: After the PEI, there was improvement in the 30-second sit-to-stand test result (16.2±7.0 times vs. 24.8±5.5 times, p=0.027), 2-minute stationary march result (98.3±27.2 times vs. 143.7±36.9 times, p=0.027), T-wall response time (104.2±55.8 seconds vs.71.0±19.4 seconds, p=0.028), memory score (89.6±21.6 vs. 111.0±19.1, p=0.028), executive function score (33.3±5.3 vs. 37.0±5.1, p=0.046), and total Literacy Independent Cognitive Assessment score (214.6±30.6 vs. 241.6±22.8, p=0.028). Electroencephalography demonstrated that the beta power in the frontal region was increased, while the theta power in the temporal region was decreased (all p<0.05). Conclusions: Our HIIT PEI program effectively improved cognitive function, physical fitness, and electroencephalographic markers in elderly individuals; thus, it could be beneficial for improving functional brain activity in this population.

Background and Purpose Torrance Tests of Creative Thinking (TTCT) is a well-known and commonly used measure of creativity. However, the TTCT-induced creative hemodynamic brain activity is rarely revealed. The purpose of this study is to elucidate the neural correlates of creative thinking in the setting of a modified version of the figural TTCT adapted for an functional magnetic resonance imaging (fMRI) experiment. Methods We designed a blocked fMRI experiment. Twenty-five participants (11 males, 14 females, mean age $19.9{\pm}1.8$) were asked to complete the partially presented line drawing of the figural TTCT (creative drawing imagery; creative). As a control condition, subjects were asked to keep tracking the line on the screen (line tracking; control). Results Compared to the control condition, creative condition revealed greater activation in the distributed and bilateral brain regions including the left anterior cingulate, bilateral frontal, parietal, temporal and occipital regions as shown in the previous creativity studies. Conclusions The present revealed the neural basis underlying the figural TTCT using fMRI, providing an evidence of brain areas encompassing the figural TTCT. Considering the significance of a creativity test for dementia patients, the neural correlates of TTCT elucidated by this study may be valuable to evaluate the brain function of patients in the clinical field.
