Objectives : We investigated the long-term tolerability of escitalopram in Korean adolescents. Methods : The subjects were 37 adolescents, who had been diagnosed with depressive disorder in accordance to DSM-IV. Clinical effectiveness was assessed by Clinical Global Impression-Improvement (CGI-I) scale at the final follow-up visit. Tolerability was assessed through a medical record of the reason for discontinuation of escitalopram and documented adverse events. Results : The mean duration of treatment was $78.1{\pm}89.5$ days, and the mean dosage was $10.0{\pm}4.4$mg/day. Out of the total 37 patients, two (5%) patients sustained use of escitalopram. Twelve patients (32.4%) discontinued use of escitalopram due to target symptom remission, and 23 patients (61.9%) due to insufficient efficacy. Six patients (16.2%) had at least one documented adverse event. However, no suicidal ideation or self-injurious behavior was reported. Significant differences in clinical symptom improvement efficacy were seen between the patients who were receiving escitalopram for less than 8 weeks (4.3%, 1/13) and those for more than 8 weeks (92.9%, 13/14). There was no significant difference between the tolerability of monotherapy compared to the concomitant use group. Conclusion : The results of this study suggest that long-term use of escitalopram may result in superior efficacy than shortterm use, and is tolerable in Korean adolescents with depression.

Objectives : Gender differences in demographic characteristics, symptom presentation, and severity may influence the selection of target behaviors as well as the course and outcome of therapeutic interventions for patients with social phobia. The purpose of this study was to explore the gender differences in the symptomatic characteristics of Korean patients with social phobia. Methods : A total of 256 outpatients with social phobia at Kangbuk Samsung Hospital were included in this study. All subjects were evaluated using the Korean version of the MINI International Neuropsychiatric Interview Plus. Potential differences in demographic characteristics, severity of anxiety, and situational fear and avoidance were examined. Self-report questionnaires and interviewer-administered instruments, including the Social Phobia Scale (SPS), Social Phobia subscale of the Fear Questionnaire (FQ-social), Appraisal of Social Concerns (ASC), and Liebowitz Social Anxiety Scale (LSAS), were used to evaluate the severity of the patients' symptoms. Results : There were no gender differences in demographic characteristics, age, age at onset of social phobia, total SPS score, FQ-Social score, ASC score, and LSAS score. In addition, there was no gender difference in the severity of fear in specific social situations. However, women reported significantly higher total scores on the social helplessness category of the ASC than men (p=0.009). Conclusion : Previous studies reported that the severity of social phobia symptoms is greater in women than in men, but our results suggest that there are no significant gender differences in the severity of social phobia symptoms. Thus, gender differences among patients with social phobia are discussed in the context of traditional sex-role expectations.

Objectives The purpose of this study was to investigate clinical profile, efficacy, and safety of long-term treatment with selective serotonin reuptake inhibitors (SSRIs) in Korean autism spectrum disorders (ASDs) patients. Methods Effectiveness was assessed through a retrospective review of self-reported target symptom improvement at the last follow-up visit. Changes in illness severity and improvement were measured using the Clinical Global Impression-Severity (CGI-S) of illness and Clinical Global Impression-Improvement (CGI-I) Scales. Tolerability was assessed through a review of the reason for discontinuation of SSRI and documented adverse events. Results A total of 21 ASDs patients (aged 9 to 19 years) treated with SSRI during July 2010 to July 2011 in department of child and adolescent psychiatry of Seoul National Hospital were identified. The mean duration of SSRI treatment was 47.9 (standard deviation = 36.9) months (range 0.7-114.5), and the mean fluoxetine equivalent dosage of SSRIs was $27.1{\pm}10.8$ mg. Nineteen (90.5%) patients were using concomitant medication. We found that SSRIs were prescribed for symptoms of agitation, stereotyped behavior, aggression, depression, impulsivity and self-injury in ASDs. Ten patients (47.6%) reported improvement in their target symptom after SSRI treatment based on CGI-I scores (CGI-I ${\leq}$ 2). The side effects were reported in 5 patients (23.8%) ; vomiting (n = 2, 9.5%), excessive mood elevation (n = 1, 4.8%), insomnia (n = 1, 4.8%), somnolence (n = 1, 4.8%) and decreased appetite (n = 1, 4.8%). Self-injurious behavior was reported in one patient (4.8%). Conclusions The results of this study suggest that SSRIs may be used effectively in children and adolescents diagnosed with ASDs. However, safety issues need to be considered carefully when choosing SSRIs for treatment. Future controlled trials are needed to confirm these findings.

In this study, we selected some herbal formulation about a series of Chijasi-tang in Dongeuibogam by using web-based open program;Prescription Lineage Graph (http://164.125.206.43/PrescriptionLineageGraph.aspx). And we compared and analyzed the changes of efficacy, major target symptoms of each herbal formulation according to compositional variation of each herbal formulation. Chijasi-tang, first appeared in Sanghanlun, consists of Capejasmine and Fermented soybean, and it is mainly used to treat insomnia due to vexation, heartburn and yellow greasy tongue fur. Capejasmine can clear away irritable feverish sensation in chest by flowing downward the heat, and Fermented soybean can disperse stagnated heat throughout the chest by expelling stagnated heat from the exterior In the case of the heat stagnation caused by relapsing of disease due to overstain, Chisijisil-tang can be used. And if symptom appear more on the upper or exterior than a case of Chisijisil-tang, Seosisi-tang could be more suitable, if half exterior and half interior, Omae-tang could be for it. In addition, if symptom caused by relapsing due to improper diet, Chisijihwang-tang could be proper formulation. In the case of the heat stagnation body inside and jaundice, if it is caused by alcohol, Chijadaehwang-tang could be used for the purpose of urgent purgation, Galchul-tang would be suitable for helping the function of the spleen and the stomach and for treatment of damp-heat of the spleen and the stomach. And if it is caused by pandemic infection, Jangdal-hwan would be good formulation for it. Samhwangseokgo-tang and Yangdokchija-tang could be appropriate formulation for the raging of noxious heat and pathogenic fire caused by febrile disease with toxic yang. Daehwangeum-ja is for severe constipation due to heat-dryness with stagnated fever, Haebaek-tang is appropriate for severe diarrhea due to heat type change of Soeum. According to the result of our investigation, although there are various target causes and symptoms of each herbal formulations, whatever pathogenetic cause is, the stagnated heat in interior side is the basis of symptoms. Therefore, the purpose of including Chijasi-tang in composition of each herbal formulation is treatment of the stagnated heat. For such reason, on the fundamental or ancillary basis of Chijasi-tang plus some herbs for each therapeutic purpose.

Objective : We retrospectively assessed the efficacy of stereotactic radiosurgery (SRS) for dural arteriovenous fistulas (DAVFs) involving the transverse-sigmoid sinus and analyzed the angiographic and clinical results with our 8-year experience. Methods : Nine patients with intracranial DAVFs involving the transverse-sigmoid sinus underwent SRS using a Gamma $Knife^{(R)}$ (Elekta Inc., Atlanta, GA, USA) between 2009 and 2016. Five patients underwent SRS for residual DAVFs after embolization and four patients were treated with SRS alone. The median target volume was $1.9cm^3$ (range, 0.8-14.2) and the median radiation dose of the target was 17 Gy (range, 16-20). The median follow-up period was 37 months (range, 7-81). Results : Pulsating tinnitus (33%) was the most common symptom. DAVFs were completely obliterated in four patients (44%) and subtotally obliterated in five (56%). Six patients (67%) showed complete recovery of symptoms or signs, and three (33%) showed incomplete recovery. One patient experienced a recurrent seizure. Adverse radiation effects after SRS occurred in one patient (11%). The total obliteration rates after SRS were 16.7%, 37.5%, and 68.7% at 1, 2, and 3 years, respectively. The median interval from SRS to total obliteration of the fistula was 31 months (range, 12-38). The rates at which the symptoms started to improve were 40% at 1 month and 80% at 2 months after SRS. Symptoms started to improve at a median of 5 weeks after SRS (range, 3-21). Conclusion : SRS with or without embolization is a safe and effective treatment to relieve symptoms and obliterate DAVFs on the transverse-sigmoid sinus.

Bacteria sense their population density and coordinate the expression of target genes, including virulence factors in Gram-negative bacteria, by the N-acylhomoserine lactones (AHLs)-dependent quorum sensing (QS) mechanism. In contrast, several soil bacteria are able to interfere with QS by enzymatic degradation of AHLs, referred to as quorum quenching. A potent AHL-degrading enzyme, AiiA, from Bacillus thuringiensis has been reported to effectively attenuate the virulence of bacteria by quorum quenching. However, little is known about the role of AiiA in B. thuringiensis itself. In the present study, an aiiA-defective mutant was generated to investigate the role of AHA in rhizosphere competence in the root system of pepper. The aiiA mutant showed no detectable AHL￢-egrading activity and was less effective for suppression of soft-rot symptom caused by Erwinia carotovora on the potato slice. On the pepper root, the survival rate of the aiiA mutant significantly decreased over time compared with that of wild type. Interestingly, viable cell count analysis revealed that the bacterial number and composition of E. carotovora were not different between treatments of wild type and the aiiA mutant. These results provide evidence that AHA can play an important role in rhizosphere competentce of B. thuringiensis and bacterial quorum quenching to Gram-negative bacteria without changing bacterial number or composition.

Antimicrobial peptides (AMPs) are considered to be a promising alternative to conventional antibiotics for future generations. We identified four novel hexapeptides with antimicrobial activity: KCM11 (TWWRWW-$NH_2$), KCM12 (KWRWlW-$NH_2$), KCM21 (KWWWRW-$NH_2$), and KRS22 (WRWFIH-$NH_2$), through positional scanning of a synthetic peptide combinatorial library (PS-SCL). The ability of these peptides to inhibit the growth of a variety of bacteria and unicellular fungi was evaluated. KCM11 and KRS22 preferentially inhibited the normal growth of fungal strains, whereas KCM12 and KCM21 were more active against bacterial strains. Bactericidal activity was addressed in a clear zone assay against phytopathogenic bacteria, including Pectobacterium spp., Xanthomonas spp., Pseudomonas spp., etc. KCM21 showed the highest activity and was effective against a wide range of target organisms. Application of KCM21 with inoculation of Pectobacterium carotovorum subsp. carotovorum on detached cabbage leaves resulted in an immune phenotype or a significant reduction in symptom development, depending on the peptide concentration. Cytotoxicity of the four hexapeptides was evaluated in mouse and human epithelial cell lines using an MTT test. The results revealed a lack of cytotoxic effects.
