Pharmacotherapy of bipolar disorder is a rapidly evolving field. Mood stabilizers and anticonvulsants have varying biochemical profiles which may predispose them to different adverse effects and drug-drug interactions. Several of the new anticonvulsants appear less likely to have the problems with drug-drug interaction. To provide more effective combination pharmacotherapies, clinicians should be allowed to anticipate and avoid pharmacokinetic and pharmacodynamic drug-drug interactions. We reviewed the role of cytochrome P450 isozymes in the metabolism of the drugs and their interactions. The drug-drug interactions of several classes of drugs which used as mood stabilizers and new anticonvulsants, some of which may have psychotropic profiles, are discussed mainly in this article. Finally, potential pharmacokinetic interactions between the benzodiazepines and other coadministered drugs are discussed briefly.

Phosphoinositide-specific Phospholipase C (PI-PLC) is a second messenger of signal transducer on cell membrane. In the previous study, PLC of bovine brain has been purified three isozymes. In this paper, uterus and seminal vesicle have been purified. Two peaks of PI-PLC activity were resolved when bovine uterus and seminal vesicle proteins were chromatographed on a DEAE and phenyl TSK 5PW HPLC column. Each two peak was compared with PI-PLC I, II and III from bovine brain and we got the retention time on HPLC. The peak fractions with PLC activity were tested homogeneity with brain PLC monoclonal antibodies (Mab). Mab-labeled affigels were bounded in the range of 73.8%~97.5% with PLC I, II and III. Homogeneity of fractions were revealed that DEAE F-1 and phenyl F-1-I were highest level of PLC III in uterus and seminal vesicle and DEAE F-2 and phenyl F-2-I were mixed PLC I and II.

Mental illnesses were understood for centuries as affliction of spirit or mind. There were many efforts to reveal the nature of mind. In the past century, however, physicians recognized that psychiatric disorders are primarily diseases of the brain and that many mental illnesses are caused by abnormalities in the brain. For the evolution and development of psychiatry in the New Millenium, understanding the relationship between the brain and mind is inevitable. To understand the nature of mind, we must understand the nature of brain. The more we know the brain, the better understood are the truth of mind and it's disorders.

Four cases of intracerebral hemorrhage remote from the site of initial supratentorial craniotomy are presented. Traumatic cases are excluded in this report and all cases developed after uneventful elective craniotomy. Two patients had ruptured aneurysm and the other two had giant supratentorial tumors, one craniophayrngioma and one ependymoma. All patients were operated on supine position and no patient had preoperative hypertension. Two had hematoma in the sucortical white matter, one in the cerebellar hemisphere and the other one showed hematoma both in the cerebellar hemisphere and the supratentorial subcortical area. The size of hematoma ranged from 8-20cc in volume. No definite cause could be found except one in which the blood pressure was transiently elevated during induction of anesthesia. A possible cause might be the sudden changes of blood pressure during induction and recovery from anesthesia, overdrainage of CSF, continuous CSF drainage and sudden changes in intracranial dynamics by removal of a huge intracranial mass. One patient with intracerebellar hemorrhage needed emergency suboccipital craniectomy for removal of the hematoma. One patient shows no improvement due to aspiration pneumonia and subsequent lung abscess. Although rare, these conditions may occur after any craniotomy and surgeons should always be alert to the possibilities of such comlication, especially when intracranial pressure(ICP) was elevated.

OBJECTIVE: A Comparison of QTc prolongation for various antipsychotics and an analysis of QTc prolongation for the various types of serotonin transporter polymorphism were performed. METHOD: EKG was checked, followed by QTc measurement as Bazett's correction, and the serotonin transporter polymorphism was examined in 110 chronic schizophrenia patients were performed EKG before 24 weeks ago. We defiened QTc prolongation as over 450ms. The risk factor of sudden cardiac death were defiend as QTc prolongation and or 60ms in delta value. RESULT: The prevalence of QTc prolongation in this study was 7.3%, and the prevalence of over 60ms was 4.5%. Patients who had the risk factors were 10(9.1%). 6/52 who prescribed atypical antipsychotics and 2/58 who prescribed haloperidol showed QTc prolongation. The prevalence who had the risk factor of sudden cardiac death were 16% in atypical antipsychotics group, 3.4% in haloperidol group. QTc prolongation were observed more frequently in l/l type than s/s type. l allele frequency were 50% in QTc prolongated group, 19% in not prolongated group. l allele had an association with QTc prolongation(p<0.01). CONCLUSION: The prevalence of QTc prolongatin was frequent in chronic schizophrenia patients who were prescribed atypical antipsychotics. It has strong association with l allele of 5-HTTLPR.

OBJECTIVES: The purpose of present study was to determine the prevalence rate of tardive dyskinesia and to search for its risk factors in chronically institutionalized schizophrenic subjects. We also examined the relationship between tardive dyskinesia and both negative symptoms and cognitive impairments in the same subjects. METHODS: Subjects were 271 in-patients (174 males, 97 females) at Masan Dongsuh Hospital. They met DSM-IV criteria for schizophrenia and had been taking fixed doses of antipsychotics for at least 3 months. Tardive dyskinesia was assessed by Abnormal Involuntary Movement Scale (AIMS). Cases of tardive dyskinesia were ascertained by the criteria of Schooler and Kane (1982) and DSM-IV. The rating of psychopathology was acquired using Brief Psychiatric Rating Scale (BPRS) and Schedule for the Deficit Syndrome (SDS) and the assessment of cognitive function using Mini-Mental State Examination (MMSE). RESULTS: The prevalence of tardive dyskinesia is 50.9% and the frequency of tardive dyskinesia was high est in male above the age of fifty. But there was no statistically significant relationship between the frequency of tardive dyskinesia and both the length of hospitalization and the daily dose of antipsychotics. The frequency order of abnormal movement in the patients with tardive dyskinesia was as follows: tongue, upper extremities, lips and perioral area. We couldn't find any significant difference in the total and subscale scores of BPRS between the groups with and without tardive dyskinesia. There were no differences in MMSE scores between the groups with and without tardive dyskinesia. CONCLUSION: This study gave us that the prevalence of tardive dyskinesia was high in chronically institutionalized schizophrenic inpatients and that age was the most significant risk factor of tardive dyskinesia. The relationship between tardive dyskinesia and both negative symptoms and cognitive impairment, however, was not revealed.

Traditional symptom-based therapies of irritable bowel syndrome (IBS) are directed at the relief of individual IBS symptoms, but they are often of limited efficacy in addressing the entire symptom complex. Combinations of drugs to target bothersome symptoms are suggested as the first-line pharmacologic treatment. Increasing knowledge of the pathophysiology and molecular mechanisms of IBS has resulted in the development of several new therapeutic approaches. Thirteen consensus statements for the treatment of IBS were developed using the modified Delphi approach. Exclusion diets have modest efficacy in improving symptoms in some IBS patients. Symptom-based therapies with dietary fiber, bulking agents, laxatives, antispasmodics and laxatives are effective in the improvement of some individual symptoms, e.g. dietary fiber and bulking agents for constipation, laxatives for constipation, antispasmodics for abdominal pain and discomfort, antidiarrheals for diarrhea. 5HT3 receptor antagonists and 5HT4 receptor agonists are effective in the relief of global IBS symptoms and individual symptoms such as abdominal pain and abnormal bowel habits. A short term course of nonabsorbable antibiotics may improve global IBS symptoms, particularly in patients with diarrhea- predominant IBS. Some probiotics appear to have the potential benefit in improving global IBS symptoms. Selective C-2 chloride channel activator is more effective than placebo at relieving global IBS symptoms in patients with constipation-predominant IBS. Both tricyclic antidepressants and selective serotonin reuptake inhibitors are equally effective in relieving global IBS symptoms, and have some benefits in treating abdominal pain. Certain types of psychologic therapy may be effective in improving global symptoms in some IBS patients. Further studies are strongly needed to develop better treatment strategies for Korean patients with IBS.

PURPOSE: To demonstrate the radiologic characteristics of the pelvic actinomycosis. MATERIALS AND METHODS: We retrospectively reviewed the radiologic findings of seven patients with pathologically proven pelvic actinomycosis and analyzed the anatomical location, characteristics of the lesion and alteration of surrounding structures. RESULTS: The location of the lesions were the ovary and adnexa(n=4), rectum(n=1), cecum and terminalileum(n=1), and bladder(n=1). Three of the seven patients had a past history of intrauterine devices.Post-contrast enhanced CT showed an ill-defined mass with inhomogeneous enhancement and a tendency to invade th esurrounding normal tissue plane. CONCLUSION: Pelvic actinomycosis should be included in differential diagnosis when an unusually aggressive infiltrative mass is located in the pelvic cavity, especially in a patient with long-term use of intrauterine contraceptive devices.

Meckel Gruber syndrome consisting of an occipital encephalocele, polycystic kidney disease and polydactyly is a rare autosomal recessive disorder with a recurrence risk of 25%. Targeted ultrasonography in late embryonic or early fetal stages of pregnancy has great importance in diagnosis and management of affected pregnancy in high risk groups due to incomplete genetic mapping of meckel syndrome gene (MKS). We present a case of prenatal diagnosis at 14 weeks' gestational age of Meckel Gruber syndrome in a woman, who experienced same disorder in her previous pregnancy.

From retrospective review of medical charts of patients diagnosed as bilateral vestibulopathy during the past seven years, this study investigated incidence, etiologies, symptoms, vestibular function test findings; electronystagmography (ENG) studies, rotatory chair testing, and posturography, and post-vestibular rehabilitation (VRT) follow-up results. we have an incidence of 1.2% of all the 3423 patients who have undergone vestibular function test. Ototoxicity was the first known etiology and we had a lot of patients of idiopathic bilateral vestibulopathy. Most patients in our study had experiences of sudden onset vertigo rather than slowly progressive symptoms. The most frequently complained symptoms were dysequilibrium and oscillopsia. Post-VRT courses were better in patients whose initial gain of vestibulo-ocular reflex(VOR) was high or ascending type.
