Sleep deprivation is an extremely common event in today's society. It has caused learning cognitive skill deterioration and poor concentration, increased disease such as heart disease, diabetes and obesity, sexual function decrease, infertility increase, depression and autonomic nervous system disorder. Sleep deprivation-induced stress caused NADPH oxidase and oxidative stress. And this oxidative stress induces apoptosis. Lilii bulbus and Nelumbins semen are known to mental and physical relaxation effects. In this study, we induced sleep deprivation(SD) in Sprague-Dawley rats in water for 5 days and thereafter administered orally L. bulbus and N. semen for 5 days. Brain tissues were observed by histochemical, immunohistochemical and tunel staining. The immunoreactives of Tumor necrosis factor ${\alpha}$, Neuronal nitric oxide synthases, Phospho-SAPK/JNK and gp91-phox of the L. bulbus administered group and N. semen administered group were weaker than those of sleep deprivation group. In the L. bulbus administered group and N. semen administered group, apoptosis was decreased than that of sleep deprivation group. Proapoptotic p53, Bax, Cleaved caspase 3 immunoreactives of the administered group were weaker than those of sleep deprivation group, whereas anti-apoptotic Bcl-2 immunoreactity was stronger in the L. bulbus administered group and N. semen administered group. Antioxidant mechanism such as DJ-1, superoxide dismutase 1, Nuclear factor-like 2 immunoreactives of the L. bulbus and N. semen administered group were stronger than those of sleep deprivation group. These results demonstrate that L. bulbus, N. semen had the neuroprotective effects on the sleep deprivation-induced oxidative stress in the hippocampus.

Objectives : To report the cases of forgotten needles found in the patients' bodies since Dong-guk University Ilsan Hospital opened, and arouse considerable attention to prevent recurrence. Methods : Oriental medical doctors in the hospital has applied acupuncture on patients' bodies in case of need, and the other staffs removed the needles after treatment. Results : All the patients in the cases had cerebrovascular disease with paralysis, aphasia, cognitive disorder and disturbance of consciousness as well as dysphagia requiring gastrotomy tube and dysfunction of respiration requiring tracheal cannula. The pathways the acupuncture needles were passing through are presumed to be transtracheal via the hole of tracheal cannula in two cases, and transgastrointestinal via mouth or the opening of gastrotomy tube. The needle was excreted with stool without any harm to the patient in the latter case, while the impact of the needles on the respiratory system or thorax of the patients in the former two cases is ambiguous. The hospital has taken some measures to prevent recurrence. Conclusions : There are not a few at high-risk of occurrence of forgotten needles that might induce medical problems among patients in oriental medical clinics or hospitals. Authors expect this report arouses all the people involved in the whole procedure of acupuncture treatment, including oriental medical doctors, nurses, nurse-assistants and caregivers considerable attentions to the possible occurrence and risk of forgotten needles.

Fahr disease (FD) is a rare neurological disorder characterized by presence of abnormal and associated cell loss in certain areas of the brain, mostly in basal ganglia, thalamus, cerebellum and subcortical areas. Approximately two-thirds of the patients are symptomatic. The most common neurological manifestations include movement disorders, cognitive impairment, cerebellar signs and speech disorders. We report one case of estimated FD through brain computed tomography (bilateral calcifications of basal ganglia, thalamus, centrum semiovale, subcortical white matter of occipital lobes, cerebellum). At the first time of treatment, he complained of tremors in his upper limbs. We diagnosed the patient as deficiency of qi (氣) and movement of phlegm-heat-wind (痰熱風動) type according to symptoms and treated by herbs and acupuncture of oriental medicine. During treatments, we evaluated how well the oriental medical treatments were working using visual analogue scale (VAS) and amplitude of hands. After the oriental medical treatments about tremor, VAS dropped from 10 to 2 and amplitude of hands from 20 mm to 2 mm, but the ratio of brain calcifications was not changed. This study suggests that oriental medical treatments can be applicable to improve FD.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder characterized by motor, cognitive, and psychiatric symptoms, accompanied by marked cell death in the striatum and cortex. Stereotaxic injection of quinolinic acid (QA) into striatum results in a degeneration of GABAergic neurons and exhibits abnormal motor behaviors typical of the illness. The objective of this study was carried out to obtain basic information about whether parthenogenetic mouse embryonic stem (PmES) cells are suitable for cell replacement therapy of HD. To establish PmES cell lines, hybrid F1 (C57BL/6xCBA/N) mouse oocytes were treated with 7% ethanol for 5 min and cytochalasin-B for 4 hr to initiate spontaneous cleavage. Thus established PmES cells were induced to differentiate using bFGF (20ng/ml) followed by selection of neuronal precursor cells for 8 days in N2 medium. After selection, cells were expanded at the presence of bFGF (20 ng/ml) for another 6 days, then a final differentiation step in N2 medium for 7 days. To establish recipient animal models of HD, young adult mice (7 weeks age ICR mice) were lesioned unilaterally with a stereotaxic injection of QA (60 nM) into the striatum and the rotational behavior of the animals was tested using apomorphine (0.1mg/kg, IP) 7 days after the induction of lesion. Animals rotating more than 120 turns per hour were selected and the differentiated PmES cells (1$\times$10$^4$cells/ul) were implanted into striatum. Four weeks after the graft, immunohistochemical studies revealed the presence of cells reactive to anti-NeuN antibody. However, only a slight improvement of motor behavior was observed. By Nissl staining, cell mass resembling tumor was found at the graft site and near cortex which may explain the slight behavioral improvement. Detailed experiment on cell viability, differentiation and migration explanted in vivo is currently being studied.

Objectives: The aim of this study is to develop the strategy of promoting participation on physical activity programs among the disabled through analysis of satisfaction on the Welfare Center for the Disabled-based program. Methods: The subjects were 151 disabled people who had physical disability or brain disorder. They had participated on the physical activity programs which were opened in 13 welfare centers for the disabled of Daegu and Gyeongbuk. The data were collected by the survey for 2 weeks in May, 2011. Results: There were no differences in the satisfaction on physical activity programs by general characteristics and health status. As for cognitive factors, it were significantly different on the satisfaction by the importance of physical activity and the fitness maintenance factor (p<0.05, p<0.01). Significant differences were found in the satisfaction by the participating attitude and the participation motives, such as goal-oriented and activity-oriented motives. It were significantly different on the satisfaction by the duration, frequency per week, time per once, and components in terms of the physical activity program. Conclusions: To revitalize the physical activity-for-all project for the disabled, it needs to develop the strategy and to enhance the health education to improve their health status.

Swallowing disorders or dysphagia, which are difficulties with the act of swallowing, can occur at different phases such as oral, pharyngeal, and esophageal phase in the swallowing process. These disorders can be caused by structural, functional abnormalities or psychological problems. Dentists can actively provide patients suffering from dysphagia with comprehensive professional care, especially from the cognitive stage of food to the pharyngeal stage of the swallow. Many cases of dysphagia can be improved with careful managements based on dental professionals' knowledge, including meticulous evaluation of masticatory and swallowing functions, training on eating and swallowing, and fabrication of palatal or lingual augmentation prosthesis. The important thing is that prevention of these disorders through the oral health care instruction and planned follow-up dental visit at periodic intervals in order to manage the problems caused by anatomical, functional, and psychological reason.

Purpose: The purpose of this study was to investigate the health education needs of mothers who are nurturing children with disabilities. Method: A descriptive study was done and the participants were 108 mothers of children with disabilities such being mentally challenged, developmentally delayed or having a disability involving brain damage. The questionnaire was a health education need assessment with 11 categories(58 items) developed by Han et al. The data were analyzed using SPSS program. Results: The mean score for health education needs of the mothers of children with disabilities was 3.83 (SD=0.58) out of a maximum 5. The health education need for acquisition of knowledge and information had the highest score (4.40±0.54) followed by health education needs for cognitive development and learning (4.31±0.64), interpersonal relationships (4.04±0.65) and behavior and emotion (4.04±0.79). There were significant differences between the children's sex (t=2.08, p=.04), birth order (t=2.17, p=.03), grade of disability (F=3.32, p=.02) and sex education suitable to the child's in age. Conclusion: The health education needs of mothers of children who are disabled were very high and varied. Therefore, it was important to develop comprehensive education programs which include this content and provide opportunities for mothers of children with disabilities to receive this education.

The prevalence of pediatric obstructive sleep apnea syndrome (OSAS) is approximately 3% in children. Adenotonsillar hypertrophy is the most common cause of OSAS in children, and obesity, hypotonic neuromuscular diseases, and craniofacial anomalies are other major risk factors. Snoring is the most common presenting complaint in children with OSAS, but the clinical presentation varies according to age. Agitated sleep with frequent postural changes, excessive sweating, or abnormal sleep positions such as hyperextension of neck or abnormal prone position may suggest a sleep-disordered breathing. Night terror, sleepwalking, and enuresis are frequently associated, during slow-wave sleep, with sleep-disordered breathing. Excessive daytime sleepiness becomes apparent in older children, whereas hyperactivity or inattention is usually predominant in younger children. Morning headache and poor appetite may also be present. As the cortical arousal threshold is higher in children, arousals are not easily developed and their sleep architectures are usually more conserved than those of adults. Untreated OSAS in children may result in various problems such as cognitive deficits, attention deficit/hyperactivity disorder, poor academic achievement, and emotional instability. Mild pulmonary hypertension is not uncommon. Rarely, cardiovascular complications such as cor pulmonale, heart failure, and systemic hypertension may develop in untreated cases. Failure to thrive and delayed development are serious problems in younger children with OSAS. Diagnosis of pediatric OSAS should be based on snoring, relevant history of sleep disruption, findings of any narrow or collapsible portions of upper airway, and confirmed by polysomnography. Early diagnosis of pediatric OSAS is critical to prevent complications with appropriate interventions.

Alzheimer's disease is a neurodegenerative disorder associated with progressive loss of cognitive function and memory. Amyloid beta peptide ($A{\beta}$) is the major component of senile plaques and is known to exert its cytotoxic effect mainly by producing $H_2O_2$. Vascular endothelial growth factor (VEGF) is elevated in the cerebrospinal fluid (CSF) and brain of AD patients, and $H_2O_2$ is one of the factors that induce VEGF. Therefore, we tested whether $A{\beta}$ might be responsible for the increased VEGF synthesis. We found that $A{\beta}$ induced the production of $H_2O_2$ in vitro. Comparison of the amount of $H_2O_2$ required to induce VEGF synthesis in HN33 cells and the amount of $H_2O_2$ produced by $10{\mu}M\;A{\beta}_{1-42}$ in vitro suggested that a toxic concentration of $A{\beta}$ might induce VEGF synthesis in these cells. However, toxic concentrations of $A{\beta}$ failed to induce VEGF synthesis in several cell systems. They also had no effect on antioxidant enzymes such as glutathione peroxidase, catalase, and peroxiredoxin in HN33 cells. $Cu^{2+}$, $Zn^{2+}$ and $Fe^{3+}$ are known to accumulate in the brains of AD patients and promote aggregation of $A{\beta}$, and $Cu^{2+}$ by itself induces synthesis of VEGF. However, there was no synergistic effect between $Cu^{2+}$ and $A{\beta}_{1-42}$ in the induction of VEGF synthesis and $Zn^{2+}$ and $Fe^{3+}$ also had no effect on the synthesis of VEGF, alone or in combination with $A{\beta}$.
