■ Objectives This case report is reported to show the effect of Ukgansan and Hwangnyeonhaedok-tang on a patient who complaining myoclonic seizure due to psychogenic non epileptic seizure, occurred after traumatic stress event. ■ Methods A female patients with myolconic seizure was treated with Ukgansan and Hwangnyeonhaedok-tang during 5 days. Then we assessed dyskinesia severity by AIMS(Abnormal Involuntary Movement Scale) every two days til discharge. ■ Results Seizure decreased two days after hospitalization, then disappeared third day. There was no recurrence till discharge. When she revisited outpatients clinic, there was no symptom. ■ Conclusion This case showed the effect of Ukgansan and Hwangnyeonhaedok-tang on psychogenic epileptic seizure.

Objective:Some candidate gene polymorphisms were reported to be associated with tardive dyskinesia (TD). The aim of this study was to investigate the association of the 5-$HT_{2A}$ receptor gene polymorphisms with TD in Korean schizophrenic subjects. Method:Subjects were of 59 schizophrenic patients with TD and 60 schizophrenic patients without TD for studying of 5-$HT_{2A}$ receptor gene polymorphisms. TD was evaluated using the Abnormal Involuntary Movement Scale(AIMS). Genomic DNA was amplified by PCR and digestion with MspI and BsmI. Result:There were no statistically significant differences in the demographic variables, such as age, male to female percentage, duration of illnesses and duration of antipsychotic drug exposure between the TD group and control group. 1) T102C polymorphisms and TD Comparing the TD group and control group, the 102T/C allele was associated with a significantly increased risk for TD (${\chi}^2$=5.560, df=1, p=0.018). 2) Three AIMS categories of TD and T102C genotype. There were statistically significant differences in the three AIMS categories(${\chi}^2$=6.835, df=2, p=0.033). Conclusion:These result suggest 102T/C genotypes of the 5-$HT_{2A}$ receptor gene are related to the development of TD. The 102T/C genotypes were associated with significantly higher AIMS orofacial dyskinesia scores. These findings suggest that the 5-$HT_{2A}$ receptor gene is significantly associated with susceptibility to TD in patients with chronic schizophrenia.

P450 CYP2D6 enzyme(=debrisoquine hydroxylase) is known to metabolize many neuroleptics and some genetic polymorphisms in the CYP2D6 gene were reported to be associated with tardive dyskinesia(TD). We investigeted the association of two genetic polymorphisms in the CYP2D6 gene, $CYP2D6^*4$ and $CYP2D6^*10$, with TD in Korean schizophrenic subjects. Subjects consisted of 71 Korean schizophrenics and TD was evaluated using the Abnormal Involuntary Movement Scale (AIMS). There were no statistically significant differences in the demographic variables of age, male to female percentage and the current antipsychotic(CPZ equivalent) dose between the group with TD and the group without TD. But the duration of antipsychotic drug exposure was significantly higher in the group without TD(p=0.000, by independent t-test). The mean AIMS score in the group with TD was $11.2{\pm}6.6$(S.D.). Genotypings for the presence of $CYP2D6^*4$ and $CYP2D6^*10$ were done using PCR amplifications and endonuclease digestions. There were no statistically significant genotypic and alleleic associations between TD and $CYP2D6^*4$(by chisquare tests), and between TD and $CYP2D6^*10$(by chi-square tests). These results indicate that the $CYP2D6^*4$ and $CYP2D6^*10$ polymorphisms have no significant roles in the causation of TD.

Objectives:There is increasing evidence that the cerebellum plays an important role in cognition and psychiatric symptoms as well as motor coordination. The concept of cognitive dysmetria has been making cerebellar function in schizophrenia the focus of current studies. In other words, disruption in the corticocerebellum-thalamic -cortical circuit could lead to disordered cognition and clinical symptoms of schizophrenia. The purposes of this study were to determine cerebellar dysfunction in male schizophrenic patients semiquantitatively with ICARS and to investigate the clinical and cognitive correlates of ICARS in patients. Methods:We compared the scores of cerebellar neurologic sign using ICARS in 47 male patients with a DSM-IV-TR diagnosis of schizophrenia with 30 gender and age-matched healthy control subjects. The semiquantitative 100-point ICARS consists of 19 items divided into 4 unequally weighted subscores:posture and gait disturbances, kinetic functions, speech disorders and oculomotor disorders. All subjects were also assessed with cognitive function test. Cognitive functions were evaluated by Korean-Mini Mental Status Examination (K-MMSE), Verbal fluency test, and Clock drawing test. The patients were administered Korea version of Positive and Negative Symptom Scale(K-PANSS) to assess the symptom severity. Results:Schizophrenic patients had significantly higher scores on the ICARS than control subjects with posture and gait disturbances, kinetic functions, and oculomotor disorders. They also showed more significant impairments in cognitive function tests than control subjects. There was a significant correlation between ICARS and negative symptoms of patients. In cognitive function test, Clock drawing test was significantly associated with negative symptoms. In addition, Clock drawing test was negatively correlated with the total score of ICARS. Conclusion:In this study, we confirmed that schizophrenic patients have significant impairments in cognitive and cerebellar function, and that those were related with negative symptoms of schizophrenic patients. These results support a role of the cerebellum in schizophrenia. It is meaningful that we used a structured, and reliable procedure for rating neurological soft signs, ICARS. We hope that future prospective studies using a similar design help that rate of neurological sign should have been visible with the progression of illness.
