두부 외상은 많은 발생율과 사망율을 차지하고 있으며, 건강한 생활을 위해 큰 관심을 갖게 되었다. 신경방사선영상은 외상성 뇌손상 환자들의 진단과 치료에 필수적인 방법이다. 뇌손상의 기본 기전, 병리, 그리고 영상 소견을 이해 하는 것은 매우 중요하다. 1970년대에 Glasgow coma scale의 형상과 전산화단층촬영(CT)의 발달은 임상의사들이 두부외상에 대한 평가와 환자들의 경과를 예상하는데 극적인 변화를 주었다. 최근 자기공명영상(MRI)의 발달로 외상성 뇌손상의 형태를 더욱 이해 하게 되었고, 두부 외상의 발견율이 높아지게 되었다.

First-line therapy of depression is a pharmacological treatment. Many prescribed antidepressants modulate monoamine neurotransmitters including serotonin, norepinephrine and dopamine. Recently, Ketamine, an N-methyl-D-aspartate receptor antagonist, has received attention and has been investigated for clinical trials and neurobiological studies. Here, I introduce ketamine as a rapid-acting antidepressant.

New antidepressants have become available for clinical use in the 1990s. Before this decade, the drugs available to treat depression consisted essentially of monoamine oxidase inhibitors, tricyclic antidepressants, and lithium. Following the introduction of SSRIs, the options have expanded and now include SSRIs, nefazodone, venlafaxine, mirtazapine, reboxetine, tianeptine. Newer antidepressants possess a variety of pharmacological characteristics that are relevant to the choice of an antidepressant for clinical use. This review summarizes some of the major pharmacological characteristics among the drugs.

While depression is certainly a prevalent disorder, it is often severe and debilitating and does not always have the good prognosis we have been led to expect. Social approaches to affective disorders have not been subjected to the same level of scrutiny as the interventions used in the management of schizophrenia. Psychosocial Rehabilitation is now at a critical stage. Psychoeducation, social skill training, cognitive remediation, family education, vocational rehabilitation and case management programs are essential for the rehabilitation of chronic depression.

The completion of the rough draft of the human genome is a remarkable achievement. It provides the overall structures of huge DNA molecules that constitute the genome and an outline of the information needed to create a human being. This paper reviewed new ideas, projects, and scientific advances made by the Human Genome Project. We also discussed the future of medicine and biomedical research in postgenomic era.

To consider current concepts of epilepsy further, the brief review begins with a discussion of what is epilepsy, discribes multifactorial nature of epileptic disorders, and ends with a presentation of current classifications. A combination of the standard antiepielptic drugs(AEDs) may be necessary to treat intractable seizures, but no studies have been done to indicate an optimal combination. The new AEDs provide alternative choices, but questions remain about the optimal timing and manner of administration. AEDs selection must individualized, no drug of choice can be named for all patients.

Depression is a frequent cause of suicide. Although there have been reports that SSRIs might increase suicidal ideations and behaviors, most studies found antidepressants are effective treatments of suicidal ideations and behaviors. Antidepressants have also been shown to have prophylactic effects in preventing suicidal behaviors. Most double-blind studies do not suggest a causal relationship between antidepressant and the increased suicidality. Our review results suggest that the undertreatments of depression are more significant problems with the use of antidepressants in suicidal patients.

Objects:Some studies have suggested that brain-derived neurotrophic factor(BDNF), one of the most important neurotrophins, is involved in pathophysiology of depression and suicide. This study was performed to determine whether there is an abnormality in plasma BDNF concentration in suicidal attempters. Methods:The subjects were 71 suicidal attempters who visited emergency rooms in multi-medical centers. All subjects had been interviewed by using Structured Clinical Interview for DSM-IV(SCID), Hamilton Depression Rating Scale(HDRS), Young Mania Rating Scale(YMRS), and Positive And Negative Syndrome Scale(PANSS). The severity of the suicidal behavior was measured by Lethality of Suicide Attempt Rating Scale(LSARS) and Risk-Rescue Rating(RRR) system. Seventy-one age, sex, and diagnosis matched non-suicidal psychiatric patients who were consecutively admitted to a psychiatric ward during the same period recruited as psychiatric controls. They were drug-naive or drug-free at least more than 2 months. In addition, 80 healthy controls were randomly selected as normal controls. Plasma BDNF level was measured by the enzyme linked immunosorbent assay(ELISA) methods. Results:In overall F-test, differences of the plasma BDNF levels among the groups were statistically significant(F=20.226, p<0.001). In the multiple comparisons(Scheffe), while mean levels of plasma BDNF between normal controls and non-suicidal psychiatric patients were similar(p=0.984), the BDNF levels of suicidal attempters were lower than those of other two groups(p<0.001). LSARS and RRR did not reveal any significant correlations with BDNF levels in suicidal attempters. Conclusion:These results suggest that reduction of plasma BDNF level is related to suicidal behavior and BDNF level may be a biological marker of suicidal behavior.

Objectives The aim of this study is to evaluate the association between rs6280 and rs905568 genetic polymorphism of DRD3 gene and the treatment response of amisulpride. Methods After six weeks treatment of amisulpride, 125 schizophrenia patients were interviewed based on the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression-Severity (CGI-S). The genotyping for rs6280 and rs905568 was performed using TaqMan single nucleotide polymorphism (SNP) genotyping assay. Results There was no significant difference in the frequency of genotype and allele of rs6280 between the responders and non-responders based on the total, positive, and general score of PANSS and CGI-S score. However, there was a significant association between this SNP and treatment response in the negative score of PANSS (${\chi}^2=5.23$, p = 0.022). There was no significant association between rs905568 and the response in positive, negative, general, and total PANSS score and CGI-S score. Conclusions This is the first positive association study between DRD3 gene and the treatment response of negative symptoms to amisulpride in Korean schizophrenia patients. A larger scale research on more SNP of the DRD3 gene will make a progress in the study of pharmacogenetics on the treatment response of the amisulpride.
