  • Chronic obstructive pulmonary disease (COPD) is a chronic progressive disease, characterized by irreversible airflow limitation, with a partially reversible component. The pathological abnormalities of COPD are associated with lung inflammation, imbalances of proteinase and antiproteinase, and oxidative stress, which are induced by noxious particles and gases in susceptible individuals. The physiological changes of COPD are mucus hypersecretion, ciliary dysfunction, airflow limitation, pulmonary hyperinflation, gas exchange abnormalities, pulmonary hypertension, cor pulmonale and systemic effects. The airflow limitation principally results from an increase in the resistance of the small conducting airways and a decrease in pulmonary elastic recoil due to emphysematous lung destruction. This article provides a general overview of the pathophysiology of COPD.

  • Glycogen storage disease (GSD) IV is a rare autosomal recessive inherited disorder caused by mutations in the gene coding for glycogen branching enzyme leading to progressive liver disease. GSD IV is associated with mutations in GBE1, which encodes the glycogen branching enzyme. We report a case of GSD IV with rare homozygous mutations in the GBE1 gene (c.791G>A (p.Gly264Glu), which was successfully treated by liver transplantation.

  • Alzheimer's disease(AD) is a progressive neurodegenerative disease, which is pathologically characterized by neuritic plaques and neurofibrillary tangles associated with the acetylcholinesterase, apolipoprotein E and butylcholinesterase, and by mutations in the presenilin genes PS1 and PS2, and amyloid precursor proteins (APPs)'s overexpression. The present research is to examine the inhibitory effect of CWBD on PS1, PS2 and APPs's overexpression detected by Western blotting. To verify further the effects of CWBD on cognitive deficits, we tested it on the scopolamine(1mg/kg)-induced amnesia model of the mice using the Morris water maze tests, and there were ameliorative effects on memory impairment as a protection from scopolamine. CWBD only partially blocked the increase in blood serum level of acetylcholinesterase and Uric acid induced by scopolamine, whereas blood glucose level was shown to attenuate the amnesia induced by scopolamine and increased extracellular serum level. In conclusion, studies of CWBD that has been known as anti-choline and inhibitory ablilities of APPs's overexpression could also be used further as a important research data for a preventive and promising symptomatic treatment for Alzheimer's disease.

  • Alzheimer's disease (AD) is the most common form of dementia in the aging population and is clinically characterized by a progressive loss of cognitive abilities. Pathologically, it is defined by the appearance of senile plaques - extracellular insoluble, congophilic protein aggregates composed of amyloid $\beta$ (A$\beta$) and neurofibrillary tangles (NFTs) - inyracellular lesions consisting of paired helical filaments from hyperphosphorylated cytoskeletal tau protein as described by Alois Alzheimer a century ago. These hallmarks still serve as the major criteria for a definite diagnosis of the disease. Consequently, one of the key strategy for drug development in this disease area focuses on reducing the concentration of cerebral A$\beta$ plaque by using substances that inhibit A$\beta$ fibril formation. We focused on developing inhibitors by synthesizing several kinds of aromatic molecules. The synthetic compounds were initially screened to evaluate the effective compound by tioflavin T fluorescence assay. The selected effective compounds were tested cytotoxicity and protective effect from A$\beta$-induced neuronal toxicity by cell based MTT assay with HT22 hippocampal neurons. The BBB permeability on effectors was also tested in in vitro co-culture model(HUVEC/C6 cell line). The behavior test wea carried out in mutant APP/PS1 transgenic mouse model of Alzheimer's disease. And inhibition of A$\beta$ fibril formation by the effective compound was monitored with transmitted electron microscopic images.

  • Alzheimer's disease(AD) is a progressive neurodegenerative disease, which is pathologically characterized by neuritic plaques and neurofibrillary tangles associated with the acetylchohnesterase, apolipoprotein E and butylcholinesterase, and by mutations in the presenilin genes PS1 and PS2, and amyloid precursor proteins (APPs)'s overexpression. The present research is to examine the inhibition effect of BYCNT on PS-1, PS-2 and APPs's overexpression by detected to Western blotting. To verify the effects of BYCNT on cognitive deficits further, we tested it on the scopolamine(1mg/kg)-induced amnesia model of the mice using the Morris water maze tests, and there was ameliorative effects of memory impairment as a protection from scopolamine. BYCNT only partially blocked the increase in blood serum level of acetylcholinesterase and Uric acid induced by scopolamine, whereas blood glucose level was shown to attenuate the amnesia induced by scopolamine and inreased extracellular serum level compared with only scopolamine injection. In conclusion, studies of BYCNT that has been known as anti-choline and inhibition ablilities of APPs overexpression, this could also be used further as a important research data for a preventive and promising symptomatic treatment for Alzheimer's disease.

  • Hemolytic uremic syndrome(HUS) is characterized by acute renal failure, microangiopathic hemolytic anemia, and thrombocytopenia and the most common pathogen is Escherichia coli (E. coli) O157 : H7. Ischemic colitis, which rarely occurs in children, is due to the reduced local blood flow to the intestine, tissue necrosis and secondary bacterial infection. We describe a patient who was admitted with abdominal pain, vomiting and hematochezia, and diagnosed as ischemic colitis by barium enema. This patient showed hemolytic anemia, thrombocytopenia and progressive renal failure and was subsequently diagnosed as hemolytic uremic syndrome. After hemodialysis, the patient showed improvement of symptoms and resolution of renal failure and ischemic colitis.

  • Objectives: Studies involving patients with spinobulbar muscular atrophy (SBMA), which is often referred to as Kennedy's disease, similar to those involving patients with progressive muscular disease (PMD), are rare. This paper reports a case study involving the use of Korean medicine to treat a patient with SBMA. Methods: We treated a patient with SBMA with unique symptoms by using various kinds of pharmacopuncture and herbal medicines for about two and a half years. After the treatment had ended, we evaluated the patient's conditions and the side effects of the treatment. Results: After treatment, the patient's symptoms were stabilized, and the patient suffered no abnormalities or side effects. No special changes in condition were noted during treatment period, and the patient was very satisfied with his response to treatment. Conclusion: Existing treatments have some considerable after effects and are difficult to apply in domestic clinics. In this regard, our findings should open possibilities for new clinical guidelines. Nevertheless, the limitations associated with this case study should be resolved, and more studies need to be conducted.

  • Although pathogenesis of human rheumatoid arthritis (RA) remains unclear, arthritogenic T cells and downstream signaling mediators have been shown to play critical roles. An increasing numbers of therapeutic options have been added for the effective control of RA. Nevertheless, there is still a category of patients that fails treatment and suffers from progressive disease. The recently developed immunosuppressant CP-690550, a small molecule JAK kinase inhibitor, has been implicated as an important candidate treatment modality for autoimmune arthritis. In this study, we evaluated the therapeutic effect of CP-690550 on established arthritis using an SKG arthritis model, a pathophysiologically relevant animal model for human RA. CP-690550 treatment revealed remarkable long-term suppressive effects on SKG arthritis when administered to the well-advanced disease (clinical score 3.5~4.0). The treatment effect lasted at least 3 more weeks after cessation of drug infusion, and suppression of disease was correlated with the reduced pro-inflammatory cytokines, including IL-17, IFN-${\gamma}$, and IL-6 and increased level of immunoregulatory IL-10.

  • Meniere's disease (MD) is a disease that affects the inner ear. It is formed as a result of endolymphatic hydrops. Hearing loss and vertigo are important in the diagnosis of MD. There is fluctuating and progressive hearing loss. Vertigo attacks cause severe dizziness in the patient. There are many treatment options in MD. These are hearing aid, diet, medication and surgery. In this study, we will discuss the advantages and disadvantages of the different treatment options. Treatment options have been compared to find out what the appropriate treatment is. Another concern is the importance of surgery in MD. This study is combination of qualitative and quantitative studies. Much focus will be on vertigo, and appropriate treatment options of MD will be mentioned also the importance of surgery. The main question in this study is the necessity of surgery. Surgical procedures are the most doubtful treatment option because of their indications and contraindications. In this study, it has been noticed that surgical operation should be delayed as much as possible. Priority is to try other treatment options. Surgery can be considered as a last resort. When we look at the operations performed, operations are mostly done in advanced Meniere cases.

  • Moyamoya disease (MMD) is a progressive cerebrovascular disease with unknown etiology, characterized by bilateral steno-occlusive changes at the terminal portion of the internal carotid artery and an abnormal vascular network formation at the base of the brain. MMD has an intrinsic nature to convert the vascular supply for the brain from internal carotid (IC) system to the external carotid (EC) system, as indicated by Suzuki's angiographic staging. Insufficiency of this 'IC-EC conversion system' could result not only in cerebral ischemia, but also in intracranial hemorrhage from inadequate collateral anastomosis, both of which represent the clinical manifestation of MMD. Surgical revascularization prevents cerebral ischemic attack by improving cerebral blood flow, and recent evidence further suggests that extracranial-intracranial bypass could powerfully reduce the risk of re-bleeding in MMD patients with posterior hemorrhage, who were known to have extremely high re-bleeding risk. Although the exact mechanism underlying the hemorrhagic presentation in MMD is undetermined, most recent angiographic analysis revealed the characteristic angio-architecture related to high re-bleeding risk, such as the extension and dilatation of choroidal collaterals and posterior cerebral artery involvement. We sought to update the current management strategy for hemorrhagic MMD, including the outcome of surgical revascularization for hemorrhagic MMD in our institute. Further investigations will clarify the optimal surgical strategy to prevent hemorrhagic manifestation in patients with MMD.
