Because the origins of stress are various, complex, and often indirectly-causing, reactions to stress are also various according to it's psychopathologies and mechanisms. For a proper management of stress, first of all accurate evaluation and diagnosis must be done. Then, treatment against the stress also can be considered, if necessary. In case of extreme stress, psychotropic drugs such as short-term anxiolytics or antidepressants can be used according to it's specific target symtoms. But long-term treatment of stress must be directed by increasing the individual's usual coping strategy or decreasing the externally causing stresses. Reactions to stress and drug interactions. which are not the whole of the biologic treatment strategy, are very important As a results, in our discussions, we ought to describe the issues by focusing the interactions between the drug and it's reaction to stress rather than the reaction to stress or drug itself and aimed at helping the proper treatment against the stress.

Antidepressants, in particular selective serotonin reuptake inhibitors (SSRIs), are one of the most commonly used classes of psychotropic drugs for treating children and adolescents. The US Food and Drug Administration has issued a black box warning concerning the increased risks of suicidal ideation and behavior associated with antidepressant treatment in children and adolescents. The aim of this review is to assess the risks and benefits of antidepressants in the treatment of child and adolescent psychiatric disorders.

Dopamine transporter (DAT) plays the most important role in terminating the actions of dopamines released into the synaptic cleft. DAT is also the target of various psychotropic drugs such as cocaine and amphetamine. In this study were prepared DAT-specific antibodies using the 2nd extracellular loop of rat DAT as an antigen. The 2nd extracellular loop of the rat DAT was expressed in bacterial as a fusion protein with glutathione-S-transferase, and injected ito rabbits to raise antibodies. Produced antibodies clearly recognized the rat DAT in ELISA, immunoblotting, and immumoprecipitation. As expected from the high sequence homology between the rat and human DAT, the antibodies raised for the rat DAT cross-reacted with the human DAT in the immunoblotting. Considering the specificity for DAT with wide range of applications such as ELISA, immunoblotting, and immunoprecipitation, these antibodies would be valuable tool for understanding the pharmacological actions of dopamine transporter and drug addition.

Dextromethophan and carisoprodol have been abused to obtain a hallucination for longer than 10 years in Korea. Due to their seriousness of abuse liablility, recently government decided to control them as a psychotropic agents. As these are controlled, it is necessary for us to establish the analysis of these medicine and their metabolites in hair to prove the abuse of these drugs. This study is described for the determination of dextrometorphan and carisoprodol in hair. (omitted)

We have examined the functional role of central dopaminergic processes on the behavioral pharmacological effects induced by psychotropics and red ginseng saponins of normal rats and compared with that of brain damaged rats. Desipramine and clomipramine produced, a significant depression of the locomotor activity in normal rats, but in brain damaged rats, they did not have any effect throughout the experimental period of 4 hours. Total saponin (50~200 mg/kg), PT (25~50 mg/kg), PD (25~50 mg/kg), $Rg_1$(12.5~25 mg/kg), $Rb_1$ (12.5~50 mg/kg) did not change, and high concentrations of PT (100 mg/kg), PD (100 mg/kg) and $Rg_1$ (50 mg/kg) showed a significant decrease in the locomotor activity of one hour after administration but total saponin (100 mg/kg), PD (25~50 mg/kg), Rgl (12.5 mg/kg), $Rb_1$ (12.5 mg/kg) markedly increased the locomotor activity of four hour after administration in normal rats. On the other hand, total saponin (50 mg/kg), PT (100 mg/kg) and PD (100 mg/kg) Produced a prominent stimulation of the locomotor activity in brain damaged rats. These results suggest that the inhibition of the locomotor activity induced by antidepressants was not affected by the sensitivity of cerebral DA system, whereas red ginseng saponin showed antifatigue effect and also the stimulation of the locomotor activity induced by red ginseng saponin was mediated by the inhibition of cerebral DA system. These psychotropic action of red ginseng saponins could be responsible for the beneficial effects on conditions of fatigue and decreased alertness.

Because chronic pain disorder may has multiple causes or contributing factors, including physical, psychological, and socio-environmental variables, the treatment of patients with the disorder requires biopsychosocial approaches in a multidisciplinary setting. In treating chronic pain, it is important to address functioning as well as pain, and treatment should be to increase functional capacity and manage the pain as opposed to curing it. Therefore treatment goal should be adaptation to pain or minimizing pain with corresponding greater functioning. Treatment begins with the initial assessment, which includes evaluation of psychophysiologic mechanisms, operant mechanisms, and overt psychiatric comorbidity. Psychiatric treatment of the patients requires adherence to sound pharmacologic and behavioral principles. There are four categories of drugs useful to psychiatrist in the management of chronic pain patients : 1) narcotic analgesics, 2) nonsteroidal antiinflammatory drugs, 3) psychotropic medications, and 4) anticonvulsants, but antidepressants are the most valuable drugs in pharmnacotherpy for them. Psychological treatments tend to emphasize behavioral and cognitive-behavioral modalities, which are divided into self-management techniques and operant techniques. Psychodynamic and insight-oriented therapies are indicated to some patients with long-standing interpersonal dysfunction or a history of childhood abuse.

In Korea, there has been no national research on the use of antipsychotics for people with intellectual disabilities(I.D); therefore, it is difficult to identify the problems or to find solutions for problems in using antipsychotics. So, the purpose of this study analyze research findings on the use of antipsychotics for people with I.D in Japan. This research method compared and analyzed the results of research published in the journal J-STAGE and Medical Online and studied a cohort results using data. The results of the analysis are as follows. First, many antipsychotic drugs are prescribed to people with I.D, but it is difficult to accurately assess the effectiveness of the treatments. Second, it is not easy to detect side effects. Third, the potential side effects of drug interactions have been raised. The results was emphasized the need of research that accurately evaluate the drugs in survey of actual situation to ensure more safe use of antipsychotics to peoples with I.D in Korea.

To examine the double-faced thymoleptic(antidepressant and antimanic) effects of risperidone in mood disorders, this article reviews the psychotropic-induced mania, thymoleptic effects of antipsychotics, therapeutic effects of risperidone and risperidone(RIS)-induced mania(RIM) in mood disorders, risk factors of RIM, possible neurochemical mechanism of these thymoleptic effects, pathophysiological and clinical significance of thymoleptic effects, and suggestive clinical guideline of RIS in mood disorders. RIS appeared effective for bipolar disorder at a lower dose than that recommended for schizophrenia, especially in the cases of maintenance of mood stabilizers, and gradual titration from low doses. Manic induction/exacerbation can occur by chance during RIS treatment in mood disorders, schizoaffective disorders, and schizophrenias. The possible risk factors for RIM are refractory mood disorder, especially in bipolar I disorder with poor initial response ; refractory schizoaffective disorders, especially in bipolar type with poor initial response ; refractory chronic schizophrenias, especially with initial responses ; psychotic features ; higher initial doses ; rapid titration ; combined therapy with antidepressants in refractory depression ; and RIS monotherapy in mania/hypomania. RIS is a drug that preferentially block 5-HT2 receptors. The effects of low dose are due mainly to the blockade of 5-HT2 receptors. There are more gradual increase in D2 blockade with increasing dose and this D2 blocking properties become apparent at higher doses. This may be related to a modulation of dopaminergic transmission by 5-HT2 antagonism at lower doses with the direct action of RIS on DA receptors coming into play at higher dose. The serotonergic antagonistic effect may be important for its effects on depressive symptoms. This, together with adequate blo-ckade of D2 receptors, may not necessarily lead to destabilization of mood disorder, but rather to more therapeutic effects. Therefore, this dose-receptor affinity relationship with both antidepressant and antimanic effects according to treatment duration can explain a continuum of antidepressant effect, antimanic effect, behavioral stimulation, and manic/hypomanic induction/exacerbation. It was the recognition of a useful psychiatric side effects by a thoughtful observer with fertile minds that led to their ultimate utilization as psychotropic drugs, i.e., phenothiazine, MAOI, TCA, and lithium. And, in vivo pharmacological challenge by novel psychotropics, as a neurochemical probe, with more specific actions is a useful tool to select pharmacologically homogeneous subgroup of the same phenotypical(clinical) condition, to further study the unknown underlying pathogenesis of various mental illnesses. Finally, RIS may be a useful alternative or adjunctive drug for patients with mood disorders without psychotic features or refractory to treatment with standard antipsychotic drugs. The more conservative doses(tirated slowly from 1-3 mg/d) of RIS, and maintenance of mood stabilizer in the cases with risk factors of RIM are recommended in mood disorder.

The fluoxetine is one of the most frequently prescribed drugs for the treatment of depression and obsessive-compulsive disorder(OCD). This has been known as one of the most safest medication. But since the advent of this drug, there have been several reports of side effects-the mania and suicidal ideation-encountered during coadministration of fluoxetine with or without other psychotropic drugs. We experienced a case of 20 years old male OCD patient who developed into abrupt manic state and also was preoccupied with intense suicidal ideation following fluoxetine use. He was a only child in his family and his father had a history of alcoholism about 15years ago. Our patient's obsessive-compulsive symptoms have been occured since puberty. His OCD symptoms and anxiety were aggravated since joining the army. Beside these facts, we could not find any other psychiatric history such as depressive disoder and bipolar disorder. We used the fluoxetine starting dosage of 20mg and increased to 40mg at second week. About 3 weeks after the treatment, he developed sudden manic symptom and more aggravated suicidal ideation without any OCD symptoms. He felt vitalized and energetic without having enough sleep and food. These symptoms were ceased over two weeks by stopping medication. Up to this point, the reason why fluoxetine induces mania and suicidal preoccupation is unclear. But somehow the fluoxetine has effects on serotonin receptor and serotonin-dopamine regulations, thus we could make an assumption that fluoxetine can induce mania, extrapyramidal symptoms(EPS) and suicidal ideation in some part of the serotonin unbalanced patients. We think this would be the first report to remark on fluoxetine's suicidal and manic side effects in Korea. So here we present the case with the summary of reviewed articles.
