Previous experimental and clinical investigations suggest a possible role of new nootropic drug, oxiracetam, in improving cognitive performances in patients affected by organic brain syndrome. In this study, the cognitive and behavioral effects of oxiracetam treatment in patients with clinical symptoms of organic brain syndrome were evaluated. Sixty-six patients were enrolled and assigned to either oxiracetam or placebo, according to a randomized, double-blind design between two patient-groups. Either oxiracetam or placebo was orally given bid for 8 weeks ; daily dose of oxiracetam was 1600mg. All the patients, enrolled in this study, were diagnosed as having mild to moderate cognitive dysfunction as defined by a baseline Mini Mental State ExaminationKorean version (MMSE-K) score between 14 and 25. The patients under-went, at baseline, 4 weeks and 8 weeks after, routine laboratory study (CBC, SMA12, U/A, EKG) and the following neuropsychological tests ; MMSE-K, modified Korean Wechsler Intelligence Scale(MKWIS), Nurses' Observation Scale for Geriatric patients(NOSGER). Fifteen patients of whom were dropped out or excluded from the analysis because of poor compliance or violation of the protocol. Fiftyone patients (aged 54~78 years, male 25, female 26) were analyzed (vascular dementia, 30 ; senile dementia of Alzheimer type, 9 ; mixed type, 5 ; other cause, 7). Statistical analysis of the data demonstrated that the two groups were comparable at baseline. At the end of each study period the oxiracetam group scored significantly better on the majority of the tests evaluating cognitive function, psychometricity and the improvement rating scale of subjective symptoms than placebo group, in which worsening trends or no changes were seen on the whole. No side effects were noted during oxiracetam treatment. The present study, showing positive clinical findings after oxiracetam therapy, confirmed that this drug can be useful pharmacological treatment in organic brain syndrome.

Background : Dandruff is a chronic scalp condition characterized by scaling. The common causative agent is now accepted to be the lipophilic Pityrosporum ovale. Obstecive : We conducted a randomized, double-blind, parallel-group study to investigate the efficacy of Herbal Shampoo & Essense and placebo in patients with mild to moderate dandruff. Mathods : Forth-seven patients with dandruff were assigned to one of two treatment goups: Test (contaning the medication) or control (vehicle). After administering through randomizion, two groups were used with Negative sampoo for first two weeks, and used with test or control products for second two weeks. Results : 1. After 2 weeks of treatment, the numbers of P. ovale in test groups were decreased in a statistically meaningful way(p<0.01) compared with control groups. 2. After 2 weeks of treatment, average of sebum-amount in test groups were decreased from 117.55 to 92.88, in a statistically meaningful way(P<0.05, paired t-test) compared with control groups that were decreased from 115.53 to 112.46. 3. In clinical score, average of control groups is decreased from 2.82 to 1.09. on the other sides, average of test groups is decreased from 3.88 to 2.44. The change of test groups is bigger than that of control groups, both two groups was decreased in a statistically way(<0.01) Conclusion : The study demonstrated that Herbal Shampoo & Essense can be used by patients with scalf safely and effectively with almost no side-effect.

Background: In Korean medicine, carpal tunnel syndrome is treated by stimulating the acupoints around the wrist. Although a deep understanding of anatomy and guidance is needed to stimulate these acupoints to avoid undesirable side-effects, currently there are no published guidelines for acupotomy treatment. The aim of this study is to evaluate the effectiveness and safety of fluoroscopy-guided acupotomy compared with conventional acupotomy treatment. Methods: This is a randomized, patient-assessor, patient blind, parallel clinical trial. A total of 30 patients will be enrolled at Wonkwang University Gwangju Hospital, and will be allocated to either an experimental group or a control group. The experimental group will be treated using fluoroscopy-guided acupotomy and the control group will be treated using the conventional acupotomy method. Results: The primary outcome measure will be identification of a cross-section area of the median nerve measured by ultrasonography, and the secondary outcome measure will be the alleviation of pain measured by the Visual Analogue Scale, improvement in the Nerve Conduction Study, Tinel test, Phalen's test, EuroQol 5-dimension scale, and Boston Carpal Tunnel Questionnaire score. Safety components will be measured by monitoring vital signs, electrocardiographs, blood tests, general chemical tests, urine tests and pregnancy tests. In addition, observations for adverse effects will be performed during the trial. Conclusion: This study will provide a more effective, and less harmful way of treating carpal tunnel syndrome compared with conventional acupotomy. Fluoroscopy-guided acupotomy will help practitioners to be accurate in direction and depth of the needle for treating carpal tunnel syndrome.

According to the Ministry of Health and Welfare, "Status of Registered Persons with Disabilities", the number of people with disabilities is 2,494,460 as of 2015. The lowest rates of children with disabilities were intellectual disabilities (23%) and mental disorders (33.3%). The highest rates of screening were blindness (97%), heart failure (94.4%), and hearing impairment (92.7%). 65.2% of visually impaired people who have already had a disability at the time of marriage, and the remaining 34.8% can be thought to be the cause of high incidence of disability after marriage. 'SID (Seed in the Dark)' project was designed to recapture the visually impaired parent's desire for attachment and the space difficulties of the blind who want to be a normal parent to their children through a visual impairment of a father with 7-year-old daughter. Using Gear VR(Virtual Reality), the general public was able to feel the surroundings as if they had no vision and focused on the hearing. Especially, We expressed the sound wave visually and added the hilarious game element which grasps the terrain of the maze by sound wave like a 'blind person who perceives the surroundings by sound' and catches up with daughter. People with disabilities who are far from mental illness often have a form of family with children. The fact that the rate of childbirth is high means that there is relatively little problem in daily life. It is wondered that the rate of blindness among the visually impaired, which accounts for 10% of the total disabled, is the highest at 97%. This is because, in the case of the visually impaired, the obstacle is often caused by aging, accidents, or diseases due to inherited causes rather than the visual disorder. In particular, However, the fact that there is an obstacle in vision that accounts for 83% of the body's sensory organs causes other difficulties in the nursing process of children who are non-disabled. Parents do not know the face of child when their visual impairment is severe. Parents are extremely anxious about worry that they will be lost or abducted if their children are not by their side. And that the child recognizes the disability of his or her parents other than the other parents easily and takes it as a deficiency. Since visually impaired parents are mentally mature parents with non-disabled people, they may want their children not to feel deprived of their disability. The number of people with visual impairments has been increasing since 2001, and people with impairments often become disabled. In addition, there is much research on the problem of nondisabled parents who have children with disabilities, while there is relatively little interest and research on the problem of nondisabled child rearing of parents with disabilities.

Purpose : Indomethacin is widely used for the prophylaxis and treatment of patent ductus arteriosus (PDA); however, it is associated with side effects such as renal failure, intraventricular hemorrhage, and gastrointestinal bleeding. Intravenous ibuprofen has been shown to be as effective as indomethacin in prompting PDA closure. If treatment with oral ibuprofen is as effective as indomethacin, it would have the advantages of greater availability, simpler administration, and lower cost. We conducted this study to compare the efficacy and side effects of indomethacin with those of oral ibuprofen, vis-$\grave{a}$-vis on the pharmacological closure of PDA. Methods : As a randomized double-blind study, 34 preterm infants with respiratory distress syndrome and hemodynamically significant PDA were treated with either intravenous indomethacin or oral ibuprofen. Echocardiography was performed by one cardiologist who was blind to the treatment that any given infant received. The rate of ductal closure, the need for additional drug treatment or surgical ligation, clinical outcome, and the side effects of drug treatment were compared. Results : Ductal closure occurred in 16 of 18 patients (88.9%) from the indomethacin group and in 14 of 16 patients (87.5%) from the ibuprofen group (P>0.05). Three patients in the indomethacin group and four in the ibuprofen group required a second drug treatment (P>0.05). Three patients (i.e., one patient in the indomethacin group and two in the ibuprofen group) underwent surgical ligation (P>0.05). Between the two groups, there was no significant difference vis-$\grave{a}$-vis in side effects or clinical outcome. Conclusion : Compared to indomethacin, oral ibuprofen has the advantages of simpler administration and lower cost, while being as effective; in addition, there are no differences between the two drug treatments with regards to side effects or clinical outcomes. Therefore, the widespread use of oral ibuprofen should be considered in treating PDA in preterm infants.

Background : Since dysthymia begins in late childhood or adolescence and has a chronic course, long-term pharmacotherapy may be required. New generation antidepressant, moclobemide, with more acceptable side effect profiles, is effective in the treatment of dysthymia. The main objective of this study was to determine whether they exhibit comparable efficacy and tolerability in dysthymia to amitriptyline. Method and Materials : The efficacy and tolerability of the moclobemide and amitriptyline, were compared in a eight-week single-centre double-blind study in patients(n=37) with dysthymia using he HAMD-17, the Clinical Global Impression Scale(CGI), the Montgomery-Asberg Depression Rating Scale (MADRS), Efficacy Index-Therapeutic Index(EITE), 4-point Index Side Effect Scale(4-PISES), and Efficacy Index- Side Effect Scale(EISE). Results : A total of 37 patients entered the study, 19 were randomly assigned to the moclobemide group and 18 to be amitriptyline group. Demo-graphic and illness characteristics were similar in both groups. There were no significant difference between two groups at the total 17-HDRS score, the HAMD-17% improvement, the total MADRS score, CGI response, and the EITE. In the comparison of EISE between two groups, the scores of the moclobemide group were relatively lower than the amitriptylinen group in full treatment. And the differences were significant(moclobemide group $1.39{\pm}0.61$ ; amitriptyline group $2.00{\pm}0.85$, p<.001). At the 4-PISE, There was no serious or treatment threatening side effects. And there was no specific difference in side effects between two groups. The moclobemide group reported higher EIR scores than the amitriptyline group at every follow up day, but the differences were not significant. And, there was no significant differences in the scores of five HRQOL subcategories which is compared between two groups at every follow up days. Conclusions : In terms of 17-HDRS and MADRS, moclobemide and amitriptyline are equally effective at least in allevating dysthymic symptoms. But moclobemide tended to be less troubling and better tolerated than amitriptyline. Therefore, moclobemide treatment can be used as a safe, and higher satisfactory treatment strategy for the dysthymia.

Purpose: Pilocarpine as a salivation stimulant in pill form has mostly been used to relieve oral dryness for xerostomic patients but its use may often be limited due to variable side effects from systemic absorption. Therefore, the purpose of this study was to investigate the effects of pilocarpine mouthwash on salivation according to the variable concentration and duration for healthy volunteers. Related adverse effects and subjective assessment on its effects on salivation were also examined. Methods: This study was performed as placebo-controlled, double-blind, randomized clinical trial. Thirty healthy volunteers (male=23, mean age=22.2 years) were randomly allocated to 6 groups with the different concentration of pilocarpine mouthwash (placebo, 0.1%, 0.5%, 1.0%, 1.5%, and 2.0%). The whole experiment consisted of 3 sessions according to the duration of mouthwash, i.e., 1, 3, and 5 minutes with the mean wash-out period ${\geq}2$ days between the sessions. Unstimulated whole saliva was collected before and after gargling with a mouthwash. Results: Salivation of the higher concentration groups ${\geq}1%$ significantly increased than those of lower concentration group. The application period of mouthwash did not cause any changes of salivary flow rate at the higher concentrations ${\geq}1.0%$. The lower concentrations of 0.5% and 0.1% had no effects on salivation even after 5-minute mouthwash. There was no significant difference between blood pressure and pulse rate before and after use of mouthwash. Conclusions: From the results of the current study, pilocarpine mouthwash with at least 1.0% concentration more than a minute might be clinically effective in salivation without any serious side effects. Dose of mouthwash rather than duration seems to be a critical factor to salivation.

Objective : The aim of the study was to investigate the therapeutic effect of BVA in the treatment of patients with acute ankle sprain. Design : A prospective randomized double-blind study of BVA was conducted. Setting : The study was done in the Kyungwon University Seoul Hospital from August 1st, 2004 to June 15th, 2005. Patients : 30 patients diagnosed with acute ankle sprain, especially 2nd degree on the Ankle grade pain chart(AGPC) participated in the study, who were divided into two groups (A and B) randomly by a coordinator flipping a coin. Group A and B were relevant to control and BVA group respectively, of which a coordinator never informed any other participant involved. Eventually 13 of 17 in group A and 11 of 13 in Group B finished all the process of the clinical trial. Intervention : In both group A and B, The Procedure of acupuncture treatment was made similar by appearance that four acupoints such as 坵墟(GB40), 中封(LR4), 商丘(SP5), 解谿(ST41) of the injured side were selected and Normal saline aqua-acupuncture(control, as a placebo) or BVA was done and then acupuncture at 坵墟(GB40), 中封(LR4), 商丘(SP5), 解谿(ST41), 足三里(ST36), 陽陵泉(G34) of the affected side was given again. the needles were retained for 20 minutes under the infrared rays. The treatment was given daily for a week. Outcome Measures : Ankle-Hindfoot Scale (AHS) and Visual Analogue Scale(VAS) were followed by three treatments. Statistical Analysis : Analysis regarding variations in AHS and VAS is carried out by applying Mann-Whitney test and Wilcoxon signed rank test sign test with level of significance at 5%. Results : At the end of the treatment, there was significant statistical differences between the two groups in VAS and AHS as well, while at the 3rd day only a VAS showed statistical significance. In each group, both VAS and AHS showed statistical significance along with duration of treatment. Conclusions : BVA was thought to be effective alternatives for relieving symptoms of acute ankle sprain, although further study was needed on the large scale.

Background: Recent studies suggested that a preoperative block of N-methyl-D-aspartate (NMDA) receptors with NMDA antagonists may reduce postoperative pain. In this double-blind study, magnesium sulfate, a natural NMDA receptor antagonist, was administered preoperatively to investigate the effects of magnesium sulfate on postoperative pain and pulmonary function. Methods: Seventy patients who were to undergo gastrectomy under general anesthesia were randomly assigned to one of three groups. Groups 2 and 3 received intravenous magnesium, preoperatively (Group 2: 50 mg/kg bolus, 7.5 mg/kg/hr for 20 hr, Group 3: 50 mg/kg bolus, 15 mg/kg/hr for 20 hr). Group 1 received normal saline as the control group. Visual analog scale (VAS) for postoperative pain and mood, cumulative analgesic consumption, recovery of pulmonary function and side effects were evaluated at 6, 24, 48 and 72 hours after the operation. Results: In Groups 2 and 3, plasma concentration of magnesium were significantly higher than in Group 1 at 6 and 20 hours after infusion (P<0.05). There were no significant differences in the analgesic consumption, and recovery of pulmonary function and the incidence of side effects at 6, 24, 48 and 72 hours after the operation among the three groups. In Group 3, pain scores at rest measured 24 and 48 hours after operation were lower than the control group, and pain scores when deep breathing were significantly lower than the control group at postoperative 6, 24, 48, and 72 hours. Conclusions: We conclude that intravenous infusion of greater amount of magnesium has little effectiveness in reducing postoperative pain. However, further studies are needed to characterize the clinical significance of these effects on postoperative pain.
