Acupuncture has been shown to have therapeutic effects on many mental disorders such as depression, anxiety, and substance abuse in human and animal studies. Maternal separation (MS) is a risk factor in the development of mood-related disorders such as depression. This study investigated the effects of acupuncture during MS by evaluating locomotion as behavioral markers of depression and by observing changes in c-Fos expression in the limbic system (hippocampus, amygdala and cingulate cortex) to elucidate the mechanism of the therapeutic effect. The employed acupoint, Shinmun (HT7), has been clinically used to treat mental disorders. MS for 7 days beginning on postnatal day 14 induced a significant decrease in locomotion, while acupuncture treatment at acupoint HT7 resulted in a significant increase in locomotion. c-Fos immunoreactive cells in area dentate gyrus (DG) of the hippocampus were increased in the MS group, but significantly decreased in the acupuncture group. These findings suggest that acupuncture has an effect on the depression-like disorder caused by MS, possibly by modulating c-Fos expression in DC of the hippocampus.

Depression is a type of mood disorder characterized by hypochondriasis, decreased appetite, and insomnia. Depression is a disease that affects more than 100 million people worldwide. 2-Nonadecanone (NAC) is a bioactive substance that constitutes Fomes fomentarius, and NAC is expected to have an antidepressant effect. By using the forced swimming test (FST), we investigated the effects of treatment with NAC on immobility subacutely in rats after oral dosing once a day for 2 days. Serum levels of cytokine interleukin-1 beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) were determined by enzyme-linked immunosorbent assay (ELISA). Nuclear factor-2 (Nrf-2) and inducible nitric oxide synthases (iNOS) were analyzed by western blot method. NAC dose-dependently decreased immobility in the FST. NAC dosedependently decreased FST-induced increase of cytokine levels, as manifested by significantly stronger effects on $IL-1{\beta}$ and $TNF-{\alpha}$ levels at higher doses than the lowest dose of NAC. Western blot analysis showed that Nrf-2 was significantly lower in the NAC-treated group than in the disease-induced group. The iNOS results were also significantly lower in the NAC-treated group than in the other groups. Considering FST results, the antidepressant effect of NAC is effective. Considering the results of cytokine and protein expression, this anti-depressant effect may be related to the anti-inflammatory effect. Therefore, it can be said that the anti-inflammatory effect of NAC increases the antidepressant effect in the FST experiment.

연구목적 : 우울장애 환자군 내에서 과거 자살 시도 여부에 따라 정서적 및 심리적 특성의 차이를 보이는 지 분석하고자 하였다. 방 법 : 정신건강의학과 입원 환자 중 주요우울장애와 달리 분류되지 않는 우울장애로 진단된 37명을 과거 자살 시도 여부에 따라 자살시도군(N=15 ; 40.54%)과 비시도군(N=22 ; 59.46%)으로 분류하였다. BDI, BAI, HDRS, HARS, MMPI-2를 사용하여, 두 집단의 증상 심각도와 심리적 특성을 비교하고자 하였다. 결 과 : 자살시도자들은 우울 증상의 임상가 평정치인 HDRS 상에서는 비시도자들과 유의한 차이를 보이지 않았으나 BDI에서는 유의하게 높은 점수를 나타냈다. 아울러 MMPI-2 소척도 중 F, Fb, Pa, RC1, DEP, HEA, PK, AAS 상에서 비시도자들에 비해 유의하게 높은 점수를 나타냈다. 이는 자살 시도의 과거력이 있는 우울장애 환자들이 현재의 삽화 중에도 객관적인 증상의 심각도와는 별개로 비시도자들에 비해 더 심한 주관적 고통감과 자살 사고를 경험하고 있으며, 타인에 대한 적대감과 불신을 더 많이 호소하고, 신체 증상에 대한 호소와 물질 사용과 관련된 문제도 더 많이 보고하는 것으로 해석될 수 있다. 결 론 : 본 연구 결과는 우울장애 환자 중 자살 시도의 과거력이 있는 환자들이 그렇지 않은 환자들과 구분되는 정서적 및 심리적 특성을 가지고 있음을 시사한다. MMPI-2는 그러한 특성을 변별하여 자살 위험성을 평가하는데 유용성을 가지는 것으로 보인다.

Objects:It has been reported that the incidence of tardive dyskinesia(TD), the remarkable abnormal involuntary movement, was higher in the schizophrenics with high blood sugar levels and that TD had been improved by small amount of insulin-injection for 90 days. And also it was generally known that the blood lipids were higher in the schizophrenics with tardive dyskinesia. Thus, we tried to replicate the correlations of abnormal involuntary movements with blood sugar levels and blood lipids in chronic schizophrenics treated with antipsychotics. Methods:Thirty-eight male schizophrenic inpatients who were stable in clinical state with medications, were included. The patients who had been already diagnosed as diabetes mellitus(DM), organic brain disorder, substance- related disorder, physical illness were excluded and also we excluded female patients to remove the hormonal effect on TD. Eleven patients who ranked higher(above five) in the Abnormal Involuntary Movement Scale(AIMS) were assigned into 2 groups, a dibenese group and a placebo group. Diabinese or placebos were administrated for 3 weeks with antipsychotics and AIMS was rechecked. Results:There were no correlations between the total AIMS scores and blood sugar and lipids levels in all subjects. The means of total and subscale scores(objective, face, and extremity) of AIMS did not reveal statistical significances between diabinese and placebo groups. However(total, jaw, face, upper arm, and objective feeling), were statistically higher in the diabinese group than those in the placebo group. And correlations of total cholesterol(TC) with fast blood sugar(FBS), weight with body mass index(BMI) and waist, total glycerol (TG) with BMI were statistically significant. Conclusion:In this study, there were statistical significances in the changes in ratings of AIMS scores between the diabinese group and the placebo group. Application of oral hypoglycemic agent might be a way of improving abnormal involuntary movements in schizophrenics with abnormal involuntary movements or TD. Althogugh it was not certain that there were correlations of abnormal involuntary movement with blood sugar and lipids, correlations of TC/TG with AIMS, of FBS with AIMS cautiously suggest that the regular check of $HbA_1C$, waist, and weight are recommended for schizophrenics.

근육 양과 근력의 감소에 의한 근감소증은 다양한 병적 상태의 악화, 삶의 질 저하, 사망률의 증가를 동반하며, 기대수명이 증가함에 따라 앞으로도 유병률은 계속 증가할 것이다. 노화 과정에서 만성 산화 스트레스와 염증 반응의 증가는 골격근 소실의 주요 원인으로 작용하며, 에너지 대사에 필수적인 미토콘드리아의 기능 장애와 관련된 자가포식 및 세포사멸 신호의 교란은 근육 단백질의 손실을 가속화한다. 오래전부터 각종 질병의 예방 및 치료에 널리 사용되어온 동충하초의 주요 생리활성물질인 cordycepin의 약리학적 효과는 항산화 및 항염증 작용과 직접적인 관련이 있는 것으로 알려져 있다. 본 총설에서는 근감소증의 예방과 치료에의 적용을 위한 cordycepin의 세포사멸, 자가포식, 단백질의 이화작용 및 근육 재생에 중요한 위성세포의 활성에 대한 연관성을 제시하였다. 비록 현재까지 근감소증에 대한 cordycepin의 연구는 미진한 수준이지만, 그동안의 연구 결과에서 cordycepin은 노화로 인한 미토콘드리아 기능 약화를 억제하고 근육 단백질의 분해를 차단하는 데 기여할 수 있음을 알 수 있다. 또한 근세포 손상에 대한 cordycepin의 보호 효과는 항산화 및 항염증 활성과 밀접한 관련이 있음을 제안한다. 따라서 근세포의 노화방지에 관여하는 cordycepin의 분자생물학적 기전을 중심으로 보다 지속적인 기초 연구가 필요할 것으로 사료된다.
