  • Alzheimer's disease (AD) is the most prevalent form of neurodegenerative disease associated with aging in the human population. This disease is characterized by the following 4 structural changes : Atrophy of the Cortex, Parasympathetic, and other neural cells, the existence of Neurofibrillary tangles (NFTs), and the accumulation of Senile plaques. NFTs and Senile plaques is known to be the index of this disease. Senile plaques disturbs the neutro transmission and depletes of Acetylcholine. So, Recovery of Acetylcholine is the primal objective for treating Alzheimer's disease. So, Inhibiting the activity of Acetylcholine Esterase (AChE), which causes the hydrolysus of acetylcholine into choline and acetate, can be seen as a key role for treating Alzheimer's disease. Increasing body of evidence has been demonstrated that Bee Venom Acupuncture (BV) could compete with complex protein involving in multiple step of $NF-_{\kappa}B$ activation and exert the anti -inflammatory potential of combined inhibition of the prostanoid and nitric oxide synthesis systems by inhibition of IKK and $NF-_{\kappa}B$. The effect of BV through behavioral tests after memory impairment induced by Scopolamine. We examined the improving effect of BV on the Scopolamine (1 mg/Kg, i.p.)-induced memorial impairment using passive avoidance response and water maze tests in the mice. BV (0.84, $1.67\;{\mu}g/ml$) reversed the Scopolamine-induced memorial impairment in dose dependent manner. This study therefore suggests that BV acupuncture method may be useful for prevention of development or progression of AD.

  • Objective : The aims of this study were to investigate the quantitative relationship between pituitary macroadenoma size and degree of visual impairment, and assess visual improvement after surgical resection of the tumor. Methods : The medical records of patients with pituitary adenoma, who had undergone trans-sphenoidal adenectomy between January 2009 and January 2011, were reviewed. Patients underwent an ocular examination and brain MRI before and after surgery. The visual impairment score (VIS) was derived by combining the scores of best-corrected visual acuity and visual field. The relationship between VIS and tumor size/tumor type/position of the optic chiasm was assessed. Results : Seventy-eight patients were included (41 male, 37 female). Thirty-two (41%) patients experienced blurred vision or visual field defect as an initial symptom. Receiver operating characteristic curve analysis showed that tumors <2.2 cm tended to cause minimal or no visual impairment. Statistical analysis showed that 1) poor preoperative vision is related to tumor size, displacement of the optic chiasm in the sagittal view on MRI and optic atrophy, and 2) poorer visual prognosis is associated with greater preoperative VIS. In multivariate analysis the only factor significantly related to VIS improvement was increasing pituitary adenoma size, which predicted decreased improvement. Conclusion : Results from this study show that pituitary adenomas larger than 2 cm cause defects in vision while adenomas 2 cm or smaller do not cause significant visual impairment. Patients with a large macroadenoma or giant adenoma should undergo surgical resection as soon as possible to prevent permanent visual loss.

  • Insulin resistance is a risk factor for stroke or recurrent stroke. Sedentary behavior increases insulin resistance. This study aimed to identify the relationship between physical impairments and functions and insulin resistance, examining which physical impairments specifically influence insulin resistance the most. The subjects of this study were 63 stroke patients. The subject's insulin resistance and physical impairments and functions were measured using the Chedoke-McMaster Stroke Assessment (CMSA) and Stroke Impairment Assessment Set (SIAS). The study results exhibited that insulin resistance is statistically significantly related to the variable of foot according to the CMSA(r=.95, p<.05) and to the variable of lower extremity sensory function (touch) in relation to the SIAS(r=.91, p<.05). This study also revealed close correlations between insulin resistance and the variables of ankle control(${\beta}=-1.05$, p<.05) and low extremity tactile sensations(${\beta}=-1.82$, p<.05).

  • The components of Magnolia officinalis have well known to act anti-inflammatory, anti-oxidative and neuroprotective activities. These efficacies have been sold many products as nutritional supplement extracted from bark of Magnolia officinalis. Thus, to assess and compare neuroprotective effect in the nutritional supplement (Magnolia $Extract^{TM}$, Health Freedom Nutrition LLC, USA) and our ethanol extract of Magnolia officinalis (BioLand LTD, Korea), we investigated memorial improving and anti-Alzheimer's disease effects of extract products of Magnolia officinalis in a transgenic AD mice model. Oral pretreatment of two extract products of Magnolia officinalis (10 mg/kg/day in 0.05% ethanol) into drinking water for 3 months ameliorated memorial dysfunction and prevented $A{\beta}$ accumulation in the brain of Tg2576 mice. In addition, extract products of Magnolia officinalis also decreased expression of ${\beta}$-site APP cleaving enzyme 1 (BACE1), amyloid precursor protein (APP) and its product, C99. Although both two extract products of Magnolia officinalis could show preventive effect of memorial dysfunction and $A{\beta}$ accumulation, our ethanol extract of Magnolia officinalis (BioLand LTD, Korea) could be more effective than Magnolia $Extract^{TM}$ (Health Freedom Nutrition LLC, USA). Therefore, our results showed that extract products of Magnolia officinalis were effective for prevention and treatment of AD through memorial improving and anti-amyloidogenic effects via down-regulating ${\beta}$-secretase activity, and neuroprotective efficacy of Magnolia extracts could be differed by cultivating area and manufacturing methods.

  • The effect of ischemia/reperfusion-induced neuronal damage on the memory impairment were investigated using active avoidance and Morris water maze tasks in Wistar rats. Focal ischemia was induced by 1 h occlusion of the right middle cerebral artery (MCA) of Wistar male rats. Reperfusion was induced by releasing the occlusion and restoring the blood circulation for 24 h. The acquisition and preservation memory tested by active avoidance showed a significant difference between the sham and ischemia/reperfusion group. The water maze acquisition performance was also significant difference between sham and ischemia/repefusion groups in both latency and moving distance. The infarction volume was increased by the ischemia/reperfusion. Furthermore, the cresyl violet staining of the ischemia/reperfusion brain showed severe neuronal damage (pyramidal cell loss) in the cortex in addition to the striatum lesion of brain. This study shows that pyramidal cell damage in the cortex lesion may be partially related to memorial disturbance in the ischemia/reperfusion brain injury.

  • Purpose: The purposes of this study were to develop the Korean version of the trunk impairment scale (K-TIS) and to examine reliability and responsiveness of the K-TIS in patients with stroke. Methods Subjects of the study were 51 stroke patients (mean age: 57.78 years) recruited from two stroke clinics. For the interrater and test-retest reliability, two raters measured the K-TIS two times using video clips with an interval of 2 weeks. For the responsiveness, intensive physical therapy training was provided to all participants 2 times a day for one month or three months depending on the onset of the stroke and the admission rules of the two clinics. Inter-rater reliability and test-retest reliability of the K-TIS three subscales (static sitting balance, dynamic sitting balance, and coordination) scores and total scores were examined using intra-correlation coefficient ($ICC_{3,1}$) and Pearson's correlation coefficient (r). To examine responsiveness, the minimally important difference (MID) was calculated with effect size. Results: Inter-rater reliability of the K-TIS subscales and total scores were all high (ICC3,1=0.920-0.983 and r=0.924-0.984). For the test-retest reliability, $ICC_{3,1}$=0.805-0.901 and r=0.806-0.903, and the MID for acute and post-acute as well as chronic stroke patients remained in the mean change range. Conclusion: It is suggested that the K-TIS might be used for clinical and research purposes as a standardized tool for stroke patients. In addition, it can also be useful in establishment of treatment goal(s) and planning treatment program(s) for patients with stroke.

  • Alzheimer's disease (AD) is the most prevalent form of neurodegenerative disease associated with aging in the human population. This disease is characterized by the extracellular deposition of beta-amyloid peptide $(A{\beta})$ in cerebral plaques. $A{\beta}$ is derived from the ${\beta}-amyloid$ precursor protein (APP) by the enzymes, ${\beta}-$ and ${\eta}o-secretase$. Compounds that ${\beta}-$ or ${\eta}o-secretase$ inhibit activity, can reduce the production of $A{\beta}$ peptides, and thus have therapeutic potential in the treatment of AD. Increasing body of evidence has been demonstrated that Bee Venom(BV) Acupuncture could compete with complex protein involving in multiple step of $NF-{\kappa}B$ activation and exert the anti-inflammatory potential of combined inhibition of the prostanoid and nitric oxide synthesis systems by inhibition of IKK and $NF-{\kappa}B$. In this study, I investigated possible effects of BV on memory dysfunction caused by lipopolysaccharide (LPS) and $A{\beta}$ through inhibition of secretases activities and $A{\beta}$ aggregation. I examined the improving effect of BV on the LPS (2.5 mg/Kg, i.p.)-induced memory dysfunction using passive avoidance response and water maze tests in the mice. BV (0.84, $1.67\;{\mu}g/ml$) reversed the LPS-induced memorial dysfunction in dose dependent manner. BV also dose-dependently attenuated LPS-induced ${\beta}$ and ${\eta}o-secretase$ activities in cerebral cortex and hippocampus of the mice brain. This study therefore suggests that BV acupuncture method may be useful for prevention of development or progression of AD.
