Objectives : In 2002, the Korean Medication Algorithm Project for Major depressive Disorder (KMAP-MD) was published, but there has been a need for a guideline about detailed issues of depressive disorder. We revised KMAP-MDD andreestablished Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) in 2006. Methods : A questionnaire had been developed by the executive committee for KMAP-DD. The review committee consisted of 101 experienced psychiatrists. From the total of 22 questions in the questionnaire, 7 questions were evaluated for these subjects . We classified the expert opinions to 3 categories according to its confidence interval; first, second and third line. Results : SSRI and venlafaxine were the first line antidepressants (AD) for atypical and melancholic depression. For dysthymic disorder and minor depressive disorder, SSRI was recommended as the first line medications. Only AD medications was a preferred initial strategy for treating premenstrual dysphoric disorder, mild to moderate and severe non-psychotic postpartum depression. In severe psychotic postpartum depression, combination therapy of AD and atypical antipsychotics was the treatment of choice. SSRI was preferred when considering sedation, anticholinergic and cardiovascular adverse effects. Also, experts recommended mirtazapine against gastrointestinal adverse effects and bupropion in avoiding sexual dysfunction. Conclusion : These results suggest that clinicians have to consider both clinical situations and drug adverse effects in the choice of antidepressant medications.

Objectives : This study aimed to examine a correlation between the somatic complaints, emotion, vocabulary and alexithymia as a component of personality in normal persons. Methods : 204 subjects were collected by age-based systematic sampling from the 662 persons without confirmed medical illness. We used the Korean version of 20-item Toronto Alexithymia Scale(TAS-20K) to measure alexithymia. The somatic complaints were checked by the list of somatic symptoms on the diagnostic criteria of somatization disorder and major depressive episode in DSM-IV. The vocabulary was evaluated by the total number of associating-words from the spontaneous association of word and the secondary association to given words. The anxiety and depression were evaluated using 5-point self-report scale. Results : 1) The degree of alexithymia was significantly correlated with the somatic complaints, anxiety, depression. 2) The somatic complaints were significantly correlated with the anxiety and depression. 3) The number of associating-words showed negative correlation with the age. 4) The degree of alexithymia was not correlated with the number of associating-words. Conclusion : The more degree of alexithymia increased, the more somatic complaints appeared. There was a significant correlation between the degree of alexithymia, anxiety and depression. But the degree of alexithymia was not correlated with the amount of vocabulary. 연구목적 : 본 연구는 정상 성인에서 성격의 일반적인 특정으로서의 감정표현불능증과 신체적 호소, 정서상태 및 어휘와의 상관관계를 알아봄으로써 감정표현불능증에 대한 이해를 넓히고자 하였다. 방법 : 신체적 질환을 가지고 있지 않은 정상 성인에서 한국판 20항목 Toronto 감정표현불능증 척도(TAS-20K), 신체적 호소, 연상한 단어의 수, 우울과 불안을 정도를 측정하여 그 결과들간의 상관관계를 알아 보았다. 총 662명을 평가한 후 체계적 표본추출 방법을 이용하여 다시 204명을 선택하였다. 결과 : 1) 감정표현불능증의 정도는 신체적 호소, 불안, 우울의 정도와 유의한 상관관계를 보였다. 2) 신체적 호소는 불안, 우울의 정도와 유의한 상관관계를 보였다. 3) 연상한 단어의 수는 나이와 부적 상관관계를 보였다. 4) 강정표현불능증의 정도는 연상한 단어의 수와 유의한 상관관계를 보이지 않았다. 결론 : 감정표현불능증의 정도가 심할수록 신체적 호소는 더 많으며 이는 불안, 우울의 정도와 연관되어 있었으나 어휘의 양과는 유의한 관계를 발견할 수 없었다.

본 연구에서는 실험동물에서, 항우울제 투여 이후 발생하는 체중 및 식이 섭취량의 변화와 식이 효율을 비교하고, 혈액 및 세포 조직에서의 대사 관련 물질과의 연관성에 대해 확인하였다. 연구 결과 항우울제 투여 이후 식이 섭취량은 모든 약물 투여군에서 저하되었으며, 식이 효율은 fluoxetine 투여군에서 감소하였다. 실험동물에서 혈액 및 조직을 이용하여 진행한 연구에서 amitriptyline 투여군과 mirtazapine 투여군은 지방세포에서 PGC-1β, UCP-1, UCP-2, UCP3 mRNA의 발현이 유사한 결과를 보였으며, fluoxetine 투여군은 leptin과의 유의한 연관성이 나타났다. 이는 항우울제가 에너지 대사에 있어 항우울제의 기전에 따라 차이를 나타낼 가능성을 제시한다. Objectives:A diverse range of adverse effects has been linked to the application of antidepressants for the treatment of depressive disorder. Recently, evidence has been emerging of the adverse metabolic effects of antidepressants. This study investigated the effects of antidepressants on plasma glucose and other factors in the fat and muscle tissue relating to metabolism. Methods:Long-Evans-Tokushima-Ostuka (LETO) rats were used to evaluate the effects of different antidepressants. Amitriptyline, fluoxetine, and mirtazapine were administered to each of three subgroups for 4 weeks, between 11 and 15 weeks old, while a fourth subgroup was administered no antidepressant during the same period. Changes of weight and daily intake were monitored. Tissues and blood were collected at 15 weeks. Results:The fluoxetine subgroup showed lower weight gain and lower food efficacy ratio than did the other subgroups. Blood glucose and other circulating factors showed no significant differences among groups, except for the leptin levels of the fluoxetine subgroup. However, the amitriptyline and mirtazapine subgroups showed similar patterns in the response of mRNA expression of peroxisome proliferator-activated receptors gamma cofactor-1 and uncoupling protein-1, 2, 3. Conclusion:These results could indicate possible differences in metabolic response based on the kind of antidepressant used.

Comparative Study of Laparoscopy-Assisted versus Open Subtotal Gastrectomy for pT2 Gastric Cancer

전현태,김기한,김민찬,정갑중 연세대학교의과대학 2012 Yonsei medical journal Vol.53 No.5

Purpose: Laparoscopy-assisted distal gastrectomy (LADG) is a widely accepted surgery for early gastric cancer. However, its use in advanced gastric cancer has rarely been studied. The aim of this study is to investigate the feasibility and survival outcomes of LADG for pT2 gastric cancer. Materials and Methods: Between January 2004 and December 2009, we evaluated 67 and 52 patients who underwent open distal gastrectomy (ODG) and LADG, respectively, with diagnosis of pT2 gastric cancer. The clinicopathological characteristics, postoperative outcomes, and survival were retrospectively compared between the two groups. Results: There were statistically significant differences in the proximal margin of the clinicopathological parameters. The operation time was significantly longer in LADG than in ODG (207.7 vs. 159.9 minutes). There were 6 (9.0%) and 5 (9.6%) complications in ODG and LADG, respectively. During follow-up periods, tumor recurrence occurred in 7 (10.4%) patients of the ODG and in 4 (7.7%) patients of the LADG group. The 5-year survival rate of ODG and LADG was 88.6% and 91.3% (p=0.613), respectively. In view of lymph node involvement, 5-year survival rates were 96.0% in ODG versus 97.0% in LADG for patients with negative nodal metastasis (p=0.968) and 80.9% in ODG versus 78.7% in LADG for those with positive nodal metastasis (p=0.868). Conclusion: Although prospective study is necessary to compare LADG with open gastrectomy for the treatment of advanced gastric cancer, laparoscopy-assisted distal gastrectomy might be considered as an alternative treatment for some pT2 gastric cancer.

Small hydropower attracts attention because of its clean, renewable and abundant energy resources to develop. However, suitable draft-tube type is not determined yet because of its complicated internal flow and unstable turbine performance at the partial flow rate by the influence of the draft tube configuration. Therefore, it is necessary to study the influence of draft tube shape. The purpose of this study is to investigate the influence of the draft tube shape to its internal flow using CFD analysis. The results using two different computational models (draft tube without runner and draft tube with runner) are compared. The result which is computed without runner show that large secondary flow occurs at the curve area of the draft tube and the secondary flow goes out to the outlet of the draft tube. Another result which is computed with runner show that internal flow has complex flow in the whole flow field of the draft tube.
