It is the purpose of this article to present a brief and systematical behavioral methods in recent developed behavioral pharmacology. Specifically, the present review has been organized around three major topics reflecting both current research emphasis in behavioral pharmacology and methodological applications to the study of psychopharmacological actions of crude drug or herb medicine. The first major topic focuses upon the appropriate experimental design especially in the study of psychopharmacology. A large number of factors should be controlled to have a bearing on design of studies reflecting to psychological effects of drugs. The second section presents several recent methodological developments in behavioral pharmacology involving Turner's screening methods and several types of conditioning techniques. The last section calls specific attention to the observation of behavioral development processes in relation to the activity of pharmacological agents and emphasizes critical period of drug treatment.

Objectives In electroconvulsive therapy (ECT) research and practice, the precise determination of seizure duration is important in the evaluation of clinical relevance of the ECT-induced seizure. In this study, we have developed computerized algorithms to assess the duration of ECT-induced seizure. Methods Subjects included 5 males and 6 females, with the mean age of 33.1 years. Total 55 ECT sessions were included in the analysis. We analyzed the standard deviation of a finite block of electroencephalography (EEG) data and the change in the local slope of RR intervals in electrocardiography (ECG) signals during ECT-induced seizure. And then, we compared the calculated seizure durations from EEG recording (EEG algorithm) and ECG recording (ECG algorithm) with values determined by consensus of clinicians based on the recorded EEG (EEG consensus), as a gold standard criterion, in order to testify the computational validity of our algorithms. Results The mean seizure durations calculated by each method were not significantly different in sessions with abrupt flattened postictal suppression and in sessions with non-abrupt flattened postictal suppression. The intraclass correlation coefficients (95% confidence interval) of the three methods (EEG algorithm, ECG algorithm, EEG consensus) were significant in the total sessions [0.79 (0.70-0.86)], the abrupt flattened postictal suppression sessions [0.84 (0.74-0.91)], and the non-abrupt flattened postictal suppression sessions [0.67 (0.45-0.84)]. Correlations between three methods were also statistically significant, regardless of abruptness of transition. Conclusions Our proposed algorithms could reliably measure the duration of ECT-induced seizure, even in sessions with non-abrupt transitions to flat postictal suppression, in which it is typically difficult to determine the seizure duration.

Any compound which disrupts the integrity of psychological aspects of performance, in particular, cognitive ability and psychomotor function analogous to the psychological behaviors of routine life, is known to be behaviorally toxic. A significant level of behavioral toxicity will interfere with patient safety and quality of life, and also may be counter-therapeutic by exacerbating the condition that the drug was prescribed for. Now, behavioral toxicity of psychotropic drugs has become one of the main growth areas of psychopharmacological research. Evaluation of the potential of drug-induced behavioral toxicity is important not only to the experimental researcher involved in human psychopharmacology, but also to the clinical practitioner treating psychiatric patients. This article attempts to describe behavioral toxicity of the three classes of psychotropic drugs - benzodiazepines, antidepressants and neuroleptics. After a brief discussion of some methodological issues arising in the investigation of behavioral toxicity, each of these drug classes is reviewed in the context of practical importance rather than purely scientific concern. The last session summarizes some suggestions for future studies on drug-induced behavioral toxicity.

Autoimmune hemolytic anemia is a disease characterized with destruction of erythrocytes as a result of antibody produce against patient's own erythrocytes and anemia. Autoimmune hemolytic anemia can be roughly stratified into two groups according to serological features and secondary causes including drugs induced hemolytic anemia. Drugs induced autoimmune hemolytic anemia is very rare in pediatric patients. Even though hematological side effects such as leucopenia, agranulocytosis, eosinophilia, thrombocytopenic purpura and aplastic anemia might occur due to psychotropic drug use; to the best of our knowledge there is no autoimmune hemolytic anemia case due to quetiapine, an atypical antipsychotics, in literature. We hereby describe the first child case of autoimmune hemolytic anemia during quetiapine treatment.We also are pointing out that one should keep in mind serious hematological side effects with atypical antipsychotic drug use with this case report.

Prader-Willi syndrome (PWS) is a quite rare multi-systemic genetic disorder strongly associated with psychiatric illness in adults, especially psychosis. This report presents a 16-year-old female with PWS and symptoms of brief psychotic disorder with a complete resolution of symptoms under aripiprazole medication. However, an exacerbation occurred after aripiprazole reduction. Apart from a weight gain of about 2 kg over the course of two years, no adverse effects could be found. This first report on the use of aripiprazole in a subject with PWS and psychosis suggests that aripiprazole might be a promising treatment approach in this distinct group of patients.

Objective: This study was to identify whether working memory (WM) can be clearly subdivided according to auditory and visual modality. To do this, we administered the most recent and universal clinical WM measures in a mixed psychiatric sample. Methods: A total of 115 patients were diagnosed on the basis of DSM-IV diagnostic criteria and with MINI-Plus 5.0, a structured diagnostic interview. WM subtests of Korean version of Wechsler Adult Intelligence Scale-IV and Korean version of Wechsler Memory Scale-IV were administered to assess WM. Confirmatory factor analysis (CFA) was used to observe whether WM measures fit better to a one-factor or two-factor model. Results: CFA results demonstrated that a two factor model fits the data better than one-factor model as expected. Conclusion: Our study supports a modality model of WM, or the existence of modality-specific WM systems, and thus poses a clinical significance of assessing both auditory and visual WM tests.

The history of pediatric psychopharmacology is very short and the research on safety, efficacy and side effects is preliminary and long-term effect on growth and maturation is not well known yet. Clinical findings have shown that the responses to antidepressants, antipsychotics, CNS stimulants and steroids in children and adolescents might be different from adult populations. Based on these findings, this paper reviewed three issues, Firstly, in developmental pharmacokinetics. the author discussed the developmental factors affecting drug absorption, distribution, protein-binding, metabolism and excretion. Secondly, in developmental pharmacodynamics, developmental characteristics of dopamine, serotonin, norepinephrine receptors and their clinical implications were reviewed. Lastly, in pharamcogenetic part, the clinical utility of pharmacogenetics, pharmacokinetic aspects of pharmacogenetics, the pharmacodynamic aspects of pharmacogenetics, the association studies of dopamine-related alleles in neuropsychiatric disorders such as attention-deficit hyperactivity disorders or Tourette’s disorders, pharmacogenetic studies dopamine-related alleles and the pharmacogenetic studies of serotonin-related alleles. Based on these preliminary research, future pharmacogenetic applications in childhood and adolescent psychiatry were also discussed.

Pulmonary diseases distress millions of people worldwide. Numerous studies have shown an association between pulmonary disease and psychiatric disorders. Despite this, little is known about the treatment of psychiatric disorder in patients with pulmonary disease. The three main goals of this article are 1) to discuss the major disorders such as asthma, chronic obstructive pulmonary disease, hyperventilation, tuberculosis, lung cancer that most clinicians see in practice, 2) to provide an information about psychiatric treatment such as anxiety, depression, psychosis in pulmonary disease, and 3) to provide some clinically relevant suggestions about pharmacologic interactions between pulmonary and psychotropic drugs.
