Objective : Patients with mild ischemic stroke experience various sequela and residual symptoms, such as anxious behavior and deficits in movement. Few approaches have been proved to be effective and safe therapeutic approaches for patients with mild ischemic stroke by acute stroke. Sildenafil (SIL), a phosphodiesterase-5 inhibitor (PDE5i), is a known remedy for neurodegenerative disorders and vascular dementia through its angiogenesis and neurogenesis effects. In this study, we investigated the efficacy of PDE5i in the emotional and behavioral abnormalities in rats with mild ischemic stroke. Methods : We divided the rats into four groups as follows (n=20, respectively) : group 1, naïve; group 2, middle cerebral artery occlusion (MCAo30); group 3, MCAo30+SIL-pre; and group 4, MCAo30+SIL-post. In the case of drug administration groups, single dose of PDE5i (sildenafil citrate, 20 mg/kg) was given at 30-minute before and after reperfusion of MCAo in rats. After surgery, we investigated and confirmed the therapeutic effect of sildenafil on histology, immunofluorescence, behavioral assays and neural oscillations. Results : Sildenafil alleviated a neuronal loss and reduced the infarction volume. And results of behavior task and immunofluorescence shown possibility that anti-inflammation process and improve motor deficits sildenafil treatment after mild ischemic stroke. Furthermore, sildenafil treatment attenuated the alteration of theta-frequency rhythm in the CA1 region of the hippocampus, a known neural oscillatory marker for anxiety disorder in rodents, induced by mild ischemic stroke. Conclusion : PDE5i as effective therapeutic agents for anxiety and movement disorders and provide robust preclinical evidence to support the development and use of PDE5i for the treatment of mild ischemic stroke residual disorders.

본 연구는 미국의 치매노인 부양자들을 대상으로 하여 치매환자가 배우자인 경우와 부모인 경우를 분리하여 이들 두 집단의 우울증이 어떠한 차이를 보이는지 또 우울증에 영향을 미치는 요소가 어떻게 다른지를 회귀모형을 통해 분석해보았다. 분석결과에 의하면, 치매에 걸린 남편을 돌보는 아내 부양자가 치매에 걸린 부모를 돌보는 딸 부양자보다 우울증 점수가 더 높은 경향성을 보여주었다. 한편, 배우자 부양자와 딸 부양자 집단의 우울증 점수에 영향을 미치는 요소들에 어떠한 공통점과 차이점을 갖고 있는지 알아보기 위해 각각의 회귀분석을 실시한 결과는 다음과 같다. 먼저, 딸 부양자의 경우 역할부담감, 역할구속감, 그리고 문제행동이 그들의 우울증에 유의미한 영향을 주었고, 아내 부양자의 경우에는 역할부담감, 역할구속감, 문제행동, 그리고 교육수준이 우울증에 유의미한 영향을 주는 변수였으며, 마지막으로 남편 부양자에게는 오직 역할구속감과 문제행동만이 그들의 우울감에 유의미한 영향을 미치는 변수로 나타났다. 따라서 모든 부양자 집단의 우울증에 공통적으로 영향을 주는 유의미한 예측변수는 역할구속감과 문제행동이었다. 즉 부양자의 역할구속감이 클수록, 그리고 피부양자인 치매환자의 문제행동 수준이 높아질수록 부양자의 우울증 점수는 높아지는 경향성을 보였다.

Objectives We investigated the tolerability, safety, and treatment response to flexible-dose paliperidone ER in patients with non-acute schizophrenia in whom previous antipsychotic drugs were ineffective. Methods This 24-week interim analysis of the 48-week multicenter, prospective, open-label study assessed effectiveness using the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression-Schizophrenia-Severity (CGI-SCH-S) Scale, Personal and Social Performance (PSP) and Drug Attitude Inventory (DAI). Safety and tolerability were assessed using the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) and Liverpool University Neuroleptic Side Effect Rating Scale (LUNSERS). Results Effectiveness was assessed in 169 patients. Significant improvement in the PANSS total score was observed by week-1 and continued until week-24. The response rate was 33%. The CGI-SCH-S and PSP total scores significantly improved during 24 weeks ; however, no change occurred in the total DAI. Fifty-nine percent of patients reported adverse events, of which extrapyramidal symptoms were the most frequent (19.0%). The DIEPSS and LUNSERS scores were improved after 24 week. Conclusions Switching to the flexible-dose paliperidone ER from an ineffective antipsychotic drug was safe, tolerable, and showed a good treatment response in Korean patients with schizophrenia.

Objective : This study aimed to review the performance of traditional herbal prescriptions for treating dementia and present a strategy for research on dementia therapy utilizing herbal medicine. Methods : A definition was made to clarify the technology regarding the development of herbal prescriptions for treating dementia. The queries were compounded based on the initial keywords provided by experts in the field, then applied to the Web of Science database search engines from January 1986 to September 2011 to search related scientific articles. Before performing the analysis, papers were extracted from the initial search reviewed by experts and 80 articles were selected. Then, the selected papers were analyzed in terms of publish year, country, and type of herbal prescriptions. Furthermore, the research performance evaluation for treating dementia by herbal prescriptions was also created in terms of country and organization based on forward citation analysis. In addition to, for the evaluation regarding research quality, we classified and reviewed papers into two types: clinical studies and experimental studies. Results : According to the quantitative information analysis of 80 articles, the number of papers has increased by 21.9% per the yearly mean from 1995, and Japan had the largest portion within this research field. There were 34 kinds of traditional herbal prescriptions, among them Ukgansan had the highest number of studies followed by Jodeungsan, Dangkisoosan and so on. In addition, quality index as calculated by cites per paper is higher than average in Switzerland, Turkey and Japan. In the view of the evaluation on quality there were 12 clinical studies, 8 RCT reported that herbal prescriptions had efficacy at cognition, behavioral & psychological symptoms (BPSD) and activity of daily life (ADL) in various type of dementia. In experimental studies most of the studies were performed using animal models. The studies using Ukgansan were aimed at improving BPSD. The papers studied with Jodeungsan and Dangkisoosan targeted vascular dementia. Conclusions : In this study, research to develop traditional herbal prescriptions for treating dementia has the potential to improve symptoms since herbal medicines work as both multi-function and multi-target in dementia with multiple pathological or neurotoxic pathways. Therefore, the results of the research should be used in order to establish strategies to develop technology for treating dementia with traditional herbal prescriptions in the future.

The purpose of this study was to identify the trends of resourcefulness researche studies for suggesting the future direction of study. Study design, types of subjects, measurement tools, study concept, and outcome were examined by reviewing 61 research studies published from 1980 to 1999. The results were as follows: 1. There were 24 works in the 1980s and 37 works in 1990, according to the published year of resourcefulness study. Nonexperimental studies like descriptive study, correlational study and comparative study were more frequent than experimental studies. 2. Research studies that consisted of 30- 100 subjects were the most numerous with 27 studies in all. The majority of study subjects was shown as healthy students and depressive patients. 3. Most studies used Rosenbaum's Self Control Schedule(SCS) for assessing resourcefulness. Reliabilities of resourcefulness researches were cronbach ${\alpha}=.70$ or more. According to statisitical tests done for internal validity, SCS was negatively correlated to maladaptation. Factor analysis revealed that the most parsimonious structure was 3 to 6 factors. The total communality variance in the SCS was about 40 %. Other tools used with the SCS were about coping, depression, satisfaction of life and symptoms, self management and health promotion. 4. In correlational studies, concepts like depression, anxiety, and psychological symptoms were related to resourcefulness negatively. Adaptive functioning, life satisfaction and self achievement had positive correlations to resourcefulness. 5. Studies on comparison between a healthy person and depressive patient or smoker and non-smoker were done. There were coping, depression, symptom, self efficacy, health problem and self-control as comparative concepts. 6. Study subjects consisted of depressive patients in 9 of 18 experimental studies. The majority of studies were done with cognitive-behavioral therapy as an experimental intervention. The most effective treatment was revealed in high resourcefulness group. Since the above findings, resourcefulness research increased since 1980 and mostly non-experimental design for quantitative study were done. In the field of nursing, research about resourcefulness was in an initial stage. It is expected that further research needed to be done. Recommendations on the basis of the present research suggest that it is necessary to replicate studies, develop nursing intervention enhancing resourcefulness and apply it to patients with chronic diseases including cancer.

Background and Objectives:The objective of this study was to investigate the features of post-thyroidectomy subjective voice disorder by Voice Handicap Index (VHI) and Voice Symptom Scale (VOISS) through aerodynamic analysis and to investigate the appropriate voice therapy intervention. Materials and Methods:Twenty post-thyroidectomy patients who had no recurrent laryngeal nerve paralysis through laryngeal stroboscopy were enrolled for this study. Acoustic and aerodynamic evaluations were performed before operation, 2 weeks and 3 months after operation. Subjective voice evaluation was performed by VHI and VOISS. Aerodynamic evaluation was compared and analysed by maximum phonation time(MPT), phonation threshold pressure(PTP), mean air flow rate(MFR), etc. Subjective voice evaluation was surveyed through VHI and VOISS. To evaluate patients' symptoms related to functional voice disorder, scores on physical domain in VHI and VOISS were selected to be compared for each session. Results: The 10 out of 20 participants who complained of voice symptoms had no significant difference with pre-operation in acoustic evaluation, but all showed higher scores on 2 weeks and 3 months after operation compared to pre-operation, in VHI-physical domain and selected questionnaires in VOISS. They reduced MPT and increased PTP value simultaneously. Laryngeal massage and breathing training were simultaneously treated to them, 5 participants resulting in improvement in MPT and PTP compared to pre-treatment. Conclusion:Patients who complained voice change with no organic damage after thyroidectomy were all shown to have reduced MPT and increased PTP in some by aerodynamic evaluations. Reduced MPT may imply some problem in air flow beneath glottis. Increased PTP suggests much more effort in vocalization mechanism than pre-operation. Comparing aerodynamic evaluations in post-thyroidectomy may provide information on behavioral interventions. Additionally, study on laryngeal massage and breathing training simultaneously treated to patients with such voice disorder is needed to be conducted with larger number of participants.

Objectives : This study aimed to investigate the efficacy and safety of Metadate CD (MCD) when given to Korean children and adolescents with attention-deficit hyperactivity disorder (ADHD). We also explored the effects of the drug on diverse neuro-cognitive functions. Methods : Ninety-one subjects with ADHD (mean age 8.6${\pm}$2.2 years) were recruited at 6 outpatient clinics in Seoul, Korea. We used the ADHD Rating Scale (ARS), Clinical Global Impression (CGI), and comprehensive attention test (CAT) to measure the drug's effects. Results : After 0.92${\pm}$0.32mg/kg/day of MCD were administered for 57.4${\pm}$7.6 days, there was a 48.5% reduction in the mean total ARS scores (p<.001). Fifty-seven subjects (64.8%) showed either much improved or very much improved outcomes on the CGI-Improvement scale. The CGI-Severity scale also decreased from an average of 4.7 to an average of 2.9 (p<.001). Errors and response time standard deviations of the CAT, sustained attention test-to-response tasks, the flanker test, and divided attention test scores decreased after treatment (p<.05). The forward memory span of the spatial working memory test scores increased (p<.05). Thirty-five patients (39.8%) experienced side effects, of which the most common were headache (14.8%), nausea (12.5%), and anorexia (9.1%). Conclusion : This open-label study suggests that MCD is effective and safe in improving the symptoms and neurocognitive functions of Korean children and adolescents with ADHD.

Crosstalk between G-protein signaling and glutamatergic transmission within the brain reward circuits is critical for long-term emotional effects (depression and anxiety), cravings, and negative withdrawal symptoms associated with opioid addiction. A previous study showed that Regulator of G-protein signaling 4 (RGS4) may be implicated in opiate action in the nucleus accumbens (NAc). However, the mechanism of the NAc-specific RGS4 actions that induce the behavioral responses to opiates remains largely unknown. The present study used a short hairpin RNA (shRNA)-mediated knock-down of RGS4 in the NAc of the mouse brain to investigate the relationship between the activation of ionotropic glutamate receptors and RGS4 in the NAc during morphine reward. Additionally, the shRNA-mediated RGS4 knock-down was implemented in NAc/striatal primary-cultured neurons to investigate the role that striatal neurons have in the morphine-induced activation of ionotropic glutamate receptors. The results of this study show that the NAc-specific knock-down of RGS4 significantly increased the behaviors associated with morphine and did so by phosphorylation of the GluR1 (Ser831) and NR2A (Tyr1325) glutamate receptors in the NAc. Furthermore, the knock-down of RGS4 enhanced the phosphorylation of the GluR1 and NR2A glutamate receptors in the primary NAc/striatal neurons during spontaneous morphine withdrawal. These findings show a novel molecular mechanism of RGS4 in glutamatergic transmission that underlies the negative symptoms associated with morphine administration.
