This study was a preliminary study on the adolescent psychiatric patients that show the characteristics of peer group neglect or rejection. We divided the adolescent psychiatric patients(n=25) into neglect-reject group(n=15) and non-neglect group(n=10). Each patient answered 8 scales and several questions about general relationships with friends. And, both the score of each 8 scales and answer about qusetions were examined. Lastly, records of 5 cases from neglect-reject group were analyzed. The depression dimension score of SCL-90-R, anxiety dimension score of SCL-9O-R, paranoid dimension score of SCL-90-R, interaction anxiousness scale(IAS) score were significantly different between 2 groups. On the result of case analysis about 5 patients of neglect-reject group, the adolescent psychiatric patients had a tendency to be rejected or neglected in case of having developmental problems(for example, language development or cognitive impairment).

The objective of this study was to identify and compare the anti-diabetic effects of mulberry leave (ML), silkworm (SK), mulberry fruit (MF), and Cudrania tricuspidata BUREAU (CT) extracts in high fat diet (HFD)-induced obese and diabetic mice. C57BL/6N mice were assigned to six groups: normal diet (ND, n=7), HFD (n=10), HFD with 5% ML powder (ML, n=10), HFD with 2% SK powder (SK, n=10), HFD with 5% MF powder (MF, n=10), and HFD with 5% CT powder (CT, n=10). Mice were fed their assigned diet for 14 weeks. ML group showed significant reduction in levels of plasma glucose and insulin compared with the HFD group. Plasma total cholesterol (T-C) was significantly reduced by ML and SK compared with the HFD group. Plasma high-density lipoprotein cholesterol (HDL-C) and HTR (HDL-C to T-C ratio) levels of the ML, SK, MF, and CT groups were significantly elevated compared to the HFD group. Moreover, concentrations of hepatic T-C and triglycerides in the ML, SK, MF, and CT groups were significantly reduced in comparison to the HFD group. Levels of pAKT, pS6K, and pAMPK significantly increased in the ML group compared with the HFD group. Taken together, ML appears to be the most potent anti-diabetic and anti-dyslipidemic substance among sericultural products. ML could be developed as a potential agent for diabetes and its complication management.

Moyamoya disease is a disorder in which certain arteries in the brain are constricted. Blood flow can be blocked by the constriction and blood clots. The patients frequently experience transient ischemic attacks (TIA), cerebral hemorrhage, or may not experience any symptoms at all. It is reported that they have a higher risk of recurrent stroke and a distinct underlying pathophysiology. A 3-year-8-month old boy with moyamoya disease experienced cerebral infarctions five times, and he underwent a cerebrovascular anastomosis surgery four years ago. He showed swallow disturbance, general delayed development, hemiplegia, and strabismus. Also he had hypocalcified teeth with or without multiple caries lesions in all dentitions. Dental treatment under general anesthesia using sevoflurane was performed due to his lack of cooperation. Moyamoya disease is associated with various medical conditions requiring a thoughtful deliberation and a careful examination before and during dental treatment. Pain and anxiety control during dental treatment is important because hyperventilation induced by crying has been seen to trigger TIA. Both isoflurane and sevoflurane are commonly used in patients with MMD, but dynamic autoregulation is better preserved during sevoflurane than isoflurane anesthesia. So sevoflurance general anesthesia may be recommendable to manage dental patients having multiple caries with moyamoya disease.

Angelman syndrome is a rare disorder caused by deletion or inactivation of genes on the maternally inherited chromosome 15. This neurodevelopmental disorder is characterized by developmental and intellectual delay, speech impairment, sleep disturbance, seizures, motor dysfunction, and frequent laughing or smiling. Orofacial characteristics include a prominent mandible, large mouth, prominent cheeks, a tendency to rest the tongue between the dental arches, excessive drooling, and excessive chewing behavior. Patients with this syndrome usually require general anesthesia even in a simple operation, because of risk of perioperative seizure during dental procedure. This is a case report about dental treatment of a 3-year-old female patient with Angelman syndrome under general anesthesia. This case suggests that the dental treatment under general anesthesia can be considered a safe component for the uncooperative, delayed developmental patients with underlying disease. Also, periodic dental exam appointment should be made to provide the patients with preventive treatments and to make them remain familiar with the dental environment.

Objectives: To investigate the patterns of unintentional home injuries in Korea. Methods: The study population was 12,382,088 people who utilized National Health Insurance services due to injuries (main diagnosis codes S00 to T28) during 2006. Stratified samples(n=459,501) were randomly selected by sex, age group and severity of injury. A questionnaire was developed based on the International Classification of External Causes of Injury and 18,000 cases surveyed by telephone were analyzed after being projected into population proportionately according to the response rates of their strata. Domestic injury cases were finally included. Results: Domestic injuries (n=3,804) comprised 21.1% of total daily life injuries during 2006. Women were vulnerable to home injuries, with the elderly and those of lower income (medical-aid users) tending to suffer more severe injuries. Injury occurred most often due to a slipping fall (33.9%), overexertion (15.3%), falling (9.5%) and stumbling (9.4%), with severe injury most often resulting from slipping falls, falls and stumbles. Increasing age correlated with domestic injury-related disability. Conclusions: The present findings provide basic information for development of home injury prevention strategies, with focus on the elderly.

All solid-state thin film micro-batteries consisting of lithium metal anode, an amorphous LiPON electrolyte and cathode of vanadium oxide have been fabricated and characterized, which were fabricated with cell structure of $Li/LiPON/V_2O_5Pt$. The effect of various oxygen partial pressure on the electrochemical properties of vanadium oxide thin films formed by d.c. reactive sputtering deposition were investigated. The vanadium oxide thin film with deposition condition of $20\%\;O_2/Ar$ ratio showed good cycling behavior. In in-siか process, the LiPON electrolyte was deposited on the $V_2O_5$ films without breaking vacuum by r.f. magnetron sputtering at room temperature. After deposition of the amorphous LiPON, the Li metal films were grown by a thermal evaporator in a dry room. The charge-discharge cycle measurements as a function of current density and voltage variation revealed that the $Li/LiPON/V_2O_5$ thin film had excellent rechargeable properly when current density was $7{\mu}A/cm^2$. and cut-off voltage was between 3.6 and 2.7V In practical experiment, a stopwatch ran on this $Li/LiPON/V_2O_5$ thin film micro-battery. This result means that thin film micro-battery fabricated by in-siか process is a promising for power source for electronic devices.

To evaluate the biocompatibility of untreated and anodized titanium specimens, the specimens were implanted in the subcutaneous tissue of the abdominal region of female mice for two weeks. The reaction of connective tissue to specimens was histologically studied. The implants were encapsulated by fibrous connective. tissue consisting of fibroblast, fibrocyte and other cellss including neutroophil, macrophage and giant multinucleated cell. some newly formed blood vessels were located in the fibrous capsule surrounding the implant. Giant multinucleated cells were observed at the fibrous capsule adjacent to the implant. Kind of cell types and the thickness of fibrous capsules were examined quantitatively. Most of cell types located in the fibrous capsule were fibroblast and fibrocyte. The average thickness of fibrous capsules for the anodized specimens was much thinner than that of the untreated titanium specimen. Biocompatibility of titanium specimens were also studied by using cell culture method. The number of MG-63 cells was significantly increased on the anodized titanium specimens in vitro experiment. Our observations suggest that anodized titanium specimens are more effective for the improvement of biocompatibility in vivo and in vitro.

Guh Sung Y.L.S-95 (GS95) is a kind of polyacidic solution, which contains acetic acid as a main component. We investigated in the present study tile genetic toxicity of GS95 according to the standard operation procedure from Korean Institute of Toxicology. In the Salmonella typhimurium reverse mutation assay using TA1535, TA1537, TA98 and TA100, GS95 did not induce mutation up to $5,000{\mu}g/plate$. GS95 did not induce chromosome aberration in Chinese hamster lung fibroblast in the concentration range between 1.25 and 5 mg/mL. In the rodent micronucleus assay, the frequency of micronucleated polychromatic erythrocyte in GS95 treated mice were not increased up to 5,000 mg/kg compared to the vehicle treated mice. Taken all these data together, GS95 was proven to be nongenotoxic in the concentration ranges tested.

The effects of methanol extract of barely (Hordeum vulgare) on alcohol-induced damages of liver were investigated in male ICR mice. Mice were divided into three groups, control, ethanol, and ethanol plus 0.15% of barley extract. After four weeks of ethanol feeding, ethanol group significantly increased the P450 content, CYP2E1 and CYP1A2 enzyme activities, whereas ethanol plus barely group markedly decreased to levels similar to control group. Catalase activity in ethanol group was significantly lower than that in control group; however, ethanol plus barely group stimulated catalase activity as well as SOD activity significantly. These results indicated that barely extract modulated P450 enzymes for ethanol-induced liver damage and might be useful in developing functional food for alcoholic liver damage.
