OBJECT: This study was undertaken to know whether there is any therapeutic effecets of sertraline in treatment-resistant schizophrenics. METHOD: Seventy seven treatment-resistant schizophrenic patients, to whom the same antipsychotics as usual were administered, were randomly assigned to two groups; to the experimental group, sertraline was and to the controlled group, placebo was administered adjuntively for 6weeks in single blind design. We assessed psychopathology by BPRS, PANSS, YBOCS, HRSD, and SCL-90-R. RESULTS: BPRS, positive scale of PANSS, and HRSD were significantly decreased in experimental group and statistically siginificant differences between the experimental group and placebo group. Negative scale of PANSS and YBOCS were significantly decresed in experimental group but no statistically significant differences between the experimental group and placebo group. The therapeutic effect of sertraline was occurred within 3rd weeks. CONCLUSION: We suggested that sertraline may be useful in the treatment of schizophrenic symtom in treatment-resistent schizophrenia, especially in positive and depressive symptoms.

OBJECTIVES: Hippocampal formation and entorhinal cortex play a part in learning and memory. This study sought to investigate the change of cell-death controlling factors in the hippocampal formation and entorhinal cortex of aged rats. METHODS: Ten aged rats and ten controls were studied. We performed immunocytochemical method using antibodies against NOS, VIP, c-fos , bcl-2, bax and p53 and in situ hybridization. RESULTS: 1) The number of nNOS-immunoreactive(IR) neurons in the entorhinal cortex was significantly decreased in the aged rats(>30%). Morphologically, the number of dendritic branches seemed to be decreased and the length of dendrites showed a tendency to by shortened in the aged group. A major loss of nNOS mRNA positive neurons was observed in the hippocampal formation of the aged rats(>30%). 2) VIP-IR neurons were predominantly bipolar cell. VIP-IR cells were mildly decreased in the hippocampus and subiculum(<15%), and moderately decreased in the dentate gyrus and entorhinal cortex of the aged rats(15-30%). The number and length of dendritic branches also appeared to have decreased and shortened in the aged group. 3) c-Fos immunoreactivity at cellular level was restricted only to the nucleus. c-Fos-IR nuclei were moderately decreased in the hippocampus(15-30%), and severely decreased in dentate gyrus, subiculum and entorhinal cortex of the aged rats(>30%). 4) Bcl-2 mRNA positive neurons were moderately decreased in the hippocampus, subiculum and entorhinal cortex(15-30%), and severely decreased in dentate gyrus of the aged rats(>30%). 5) Bax-IR neurons were similarly distributed between the control and the aged rats, but bax-IR neurons of the aged group, as compared to the control group, were weakly immunostained. 6) P53-IR neurons were only observed in hippocampal CA1 region of the aged rats. CONCLUSION: These results indicate the involvement of neuronal system containing NOS, VIP, c-fos, bcl-2 and p53 in the brain aging process, and provide the morphological evidence for the changes in immunoreactivity of cell-death controlling factors in the hippocampal formation and entorhinal cortex of aged rats.

Authors report a case of rapid cycling affective disorder(RCAD) who has suffered severe premenstrual syndrome since her monarch. Even if what relationship and etiology these disorders may have are undetermined, premenstrual syndrome and RCAD indeed share many characteristics and estrogen may have central role in these disorders. Patient showed a significant decrease of cerebral blood flow of right temporal area on SPECT It is impressive that carbamazepine was more effective than lithium in treatment of this RCAD case.

OBJECTS: This study was purposed to investigate the relationship between urine HVA and 5-HIAA concentrations and clinical symptoms in chronic schizophrenia. METHODS: 272 patients with chronic schizophrenia, diagnosed by DSM-IV criteria, were performed to measure urine HVA and 5-HIAA concentrations and to evaluate the clinical symptoms by using BPRS, PANSS, YBOCS and HAM-D. RESULTS: Urine HVA and 5-HIAA concentrations showed significant correlation with BPRS, positive scale, negative scale and general psychopathology in PANSS and urine HVA/5-HIAA ratios found no significant correlation. Urine HVA concentrations showed significant correlattion with urine 5-HIAA concentrations and urine HVA/5-HIAA ratios had a negative correlation with urine 5-HIAA concentration. As a result of stepwise multiple regression, urine HVA concentrations were significantly correlated with BPRS and positive scale in PANSS and Urine 5-HIAA concentrations were significantly correlated with BPRS. Urine HVA/5-HIAA ratios had significant correlation with HAM-D and BPRS. CONCLUSION: These findings support the hypothesis that the role of central dopamine and serotonin system and the functional interaction of both neurotransmitters are important to clinical symptom formation of chronic schizophrenia.

Despite the indications that psychodynamic factors may be important in understanding and treatment of panic disorder, these have not been studied systematically. In this report, self-rating Ewha Defense Mechanism Test(EDMT) was used to test the hypotheses that 1) panic patients would use different defense mechanism from normal controls, 2) panic patients would use lower-maturity defenses than normal controls. Twenty-two subjects meeting the DSM-IV criteria for panic disorder and 22 normal controls were given self-rating EDMT, and were compared about the use and maturity level of defenses between the two groups. Panic subjects scored significantly much higher than normal controls on the defenses of displacement and acting out, and on the controlling as a major defense mechanism. Also, the use of neurotic defense mechanisms was more frequent in panic subjects.

OBJECTIVE: The purpose of this study was to elucidate the biological correlates of schizophrenia by measuring the change of serum immuneglobulin and complement levels and investigating a relationship of clinical symptoms to serum immunoglobulin and complement levels in schizophrenics. METHODS: The subjects were 27 inpatients, 13 men and 14 women, who met the diagnostic criteria for schizophrenia by Diagnostic and Statistical Manual of Mental Disorders IV(DSM-IV) and 24 normal controls, 8 men and 16 women. The serum immunoglobulin and complement levels of patients were measured at admission day and artier 2 weeks of treatment. Immunoglubulins and complement levels were obtained in serum using nephelometry. Positive and Negative Syndrome Scale(PANSS) were used to determine the clinical symptoms . RESULTS: 1) The serum IgG(p<.01) and IgM(p<.05) levels of schizophrenics measured at admission day were significantly lower than those of normal controls. 2) The serum C3 level significantly(p<.01) correlated with positive syndrome score. 3) The serum IgG levels of schizophrenics were significantly(p<.05) increased artier 2 weeks of treatment, especially in female schizophrenics. 4) The correlations of serum IgG, IgA, IgM, C3 and C4 to positive and negative syndrome scores of PANSS after treatment failed to get significant result. CONCLUSION: It Is suggested that the Immune function of schizophrenics appears to be decreased when compared with normal controls and is slightly increased with clinical improvement. Significant correlation between C3 and positive syndrome score at admission suggests possibility of immunologic marker of acute schizophrenia.

OBJECTIVES: This prospective study was designed to investigate the effect of serotonergic atypical antipsychotics on serum creatine phosphokinase. METHOD: The subjects were 60 inpatients who were medicated risperidone and nemonapride, atypical antipsychotics. The symptoms of NMS such as fever and muscle rigidity and the level of CRK of all subjects were assessed on the 5th, 10th, 20th, and 30th medication day. RESULTS: Sociodemographic variables, such as sex and mean age and number of intramuscular injection were not different between the risperidone and the nemonapride group. Maximum dosage of antipsychotics (chlorpromazine equivalent) was significantly higher in the nemonapride group. Fever and muscle rigidity were not different between two groups (p>0.05). The change of serum creatine phosphokinase was significantly higher in the risperidone group than the nemonapride group (p<0.05). CONCLUSIONS: Serum CRK showed a significant increase in risperidone than nemonapride group. Such a finding is primarily caused by the effect of atypical antipsychotics mediating serotonergic effects. It is not recommanded to stop the medication by misunderstanding the effect as a prodrome symptom of NMS.

OBJECTIVES: This study investigated PTSD prevalence, symptoms, depressed mood and anxiety, comparing two groups of the patients in trauma; one who had experienced the loss of consciousness (group "A" here after) and the other group of patients who had not(group "B" here after). METHOD: Subjects were 120 patients(age18-66) who had received trauma(traffic accident, fall down) more than 1 month. Before they consisted of 56 patients who had experienced the loss of the consciousness(46.7%) and 64 who had not(53.3%). Men were 69 and women were 51. Clinician administered PTSD Scale, Beck Depression Inventory, State Trait Anxiety Inventory-I, II were administered. The factors such as sociodemographic variables, unconsciousness at the time of trauma, memory about traumatic accidents were considered. RESULT: Out of 120 subjects, 30 patients(25%) were diagnosed as PTSD: 17 from 56(30.4%) and 13 from 64(20.3%) were found in the group "A" and "B" respectively. Prevalence of PTSD was higher in the group "A". However, there was no significant difference between two groups(X2=1.607, p>0.05). The CAPS of group "A" showed significantly high frequency in the loss of interest, detachment, restricted affect, sleep difficulty, irritability/anger, concentration difficulty(p<0.05), while the group "B" scored high in intrusive recall and increased startle. The scores of BDI, STAI-I, II were significantly higher in the group "A"(t=-3.16, p<0.05)(t=-2.75, p<0.05, t=-3.38, p<0.05). CONCLUSION: PTSD was more frequent and depressed mood and anxiety appeared more often in the group who experienced the loss of consciousness. Thus the loss of the consciousness at the time of trauma prones of the aevelopment PTSD and to symptom of aepression and anxiety.

OBJECTIVES: The pharmacologic treatment of obsessive-compulsive disorder(OCD) with serotonergic antidepressant agents is well established in clinical psychiatry on the basis of serotonin hypothesis. Studies on predictive factors of treatment response to OCD are relatively scarce. The author compared the demographic factors, age of onset, length of illness, family history of mental illness, previous drug history for OCD, severity and type of symptoms between the drug responders and non-responders to find out the predicitive factors that may be related to treatment response. METHODS: The subjects were 31, both inpatients and outpatients who met the diagnostic criteria for OCD by DSM-IV and scored 20 or higher on the Yale-Brown Obsessive-Compulsive Scale(Y-BOCS) completed 12-week trial of sertraline. Y-BOCS, National Institute of Mental Health Obsessive-Compulsive Scale(NIMHOCS), Clinical Global Impression Scale(CGI) were scored to measure the changes of obsessive-compulsive symptoms, and Hamilton Anxiety Scale(HAM-A) was measured at each visit. RESULTS: 1) The responders, defined as achieving at least a 40% decrease in the Y-BOCS total score and more than a 2 point decrease in CGI score, were 17(54.8%), and non-responders were 14(45.2%). Responders tended to show later onset(p<0.1), and shorter duration of illness(p<0.05), and less previous drug therapy for OCD(p<0.05) than non-responders. There were no significant differences in family history of mental illness between the two groups. 2) The baseline Y-BOCS compulsive score was significantly lower in responders(p<0.05), although there was no significant difference in the baseline severity of other measures. 3) The obsession of contamination and washing behaviors were more frequent, but compulsive counting was not shown, in responders(p<0.05). The pathological doubt tended to be more common in nonresponders(p<0.1). CONCLUSIONS: In summary, the patients with shorter duration of illness, less prior drug therapy for OCD, and less severe compulsive behaviors, and the obsession of contamination and washing behaviors are expected to be better outcome with sertraline, whereas compulsive counting are the predictor of poor response.
