This study aimed 1) at determining the seasonal pattern of the first onset and 2) at examining different demographic and clinical factors by the seasonality of first onset, for shizophrenia, mood disorder and subtypes of each diagnosis. Finally, the 52 subjects with paranoid schizophrenia were selected from all patients who fulfilled DSM-IV criteria far schizophrenia who had been admitted to the National Seoul Mental Hospital from March 1994 to February 1995. And the 44 subjects with bipolar I disorder were selected from all patients who fulfilled DSM-IV criteria for mood disorder who had been admitted to the hospital from March 1994 to February 1996. This study was done by reviewing the hospital records about season of the first outset, demographic factors(sex, age, occupation, educated period, religion, marital status, residence and socioeconomic status) and clinical factors(age at the first onset, duration of illness, family history, length of admission, frequency of admission and treatment result). The seasonal pattern of the first onset and the different demographic and clinical factors by the season of the first onset in paranoid shizophrenia and I disorder were analyzed. The results were as follows: 1) There was no significant seasonal variation of the first onset for paranoid schizophrenia. 2) There was a significant seasonal variation of the first onset with a maximum in spring for bipolar I disorder. 3) There was no significant seasonal variation of the first onset in case of bipolar I disorder that began with the manic episode. 4) There was nonsignificant seasonal tendency to peak in spring/summer in the case of the first manic episode for bipolar I disorder. 5) There were no significant differences in demographic and clinical factors by the season of the first onset for paranoid schizophrenia and bipolar I disorder.

There appeared remarkably common disorder of water balance in psychiatric patients. Approximately 30% of the chronic inpatient population drinks fluids excessively, so called polydipsic, while 5% suffers episodes of water intoxication. Water intoxication is a serious problem characterized by profound hyponatremia and a diverse neurologic signs ranging from ataxia, confusion to death. The cause of polydipsia is even less clear. Although previous studies have suggested that it is related to cognitive dysfunction the possibility of an abnormality in the osmoregulation of thirst has not been investigated. But there is the hypothesis that polydipsic, hyponatremic schizophrenics exhibit increased neuroendocrine and behavioral sensitivity to dopamine in mesolimbic tracts, in proportion to the severity of their osmoregulatory disturbance. In order to provide the optimal clinical management of these common disturbances, the author will review their pathophysiology, assessment, treatment and relationship with mental illness.

OBJECTIVE: This study was to investigate the prevalence of tardive dyskinesia (TD) in Korean inpatients using antipsychotics and the relationship between TD and sociodemographic, clinical variables. METHODS: This study was done from January to Feburary, 2003, at the Seoul National Mental Hospital. A cross-sectional assessment of randomly selected inpatients (n=324;mean age=39.73+/-9.63years) with DSM-IV schizophrenia, schizoaffective, bipolar disorder was performed with standard rating instrument for TD and extrapyramidal symptoms. The relations between the prevalence of TD and sex, age, length of medication and dosage of antipsychotics, clozapine, and other psychotropic medication, EPS were analyzed with Chi-square test or t-test. RESULTS: Using Schooler and Kane's criteria, 20 subjects (6.17%) had TD. TD was significantly less prevalent in patients receiving clozapine. There was no other significant difference between the TD and without TD groups with respect to type of antipsychotics, other psychotropic drug, antiparkinsonian drug, mood stabilizer augmentation. CONCLUSION: The result of this study have confirmed the lower prevalence of TD among inpatients using antipsychotics compared to previous investigations. The study has also replicated the association of TD with older age. Clozapine use was associated with lower prevalence rate of TD.

The purpose of this study was to examine the effects of anti-sperm antibody (ASA) on the fertilization processes using conventional IVF and ICSI procedure in human and hamster oocytes. In human IVF, we have observed restricted fertilization with sperm testing positive for ASA. (23~90% IgA, 60-97 % IgG). However, if ICSI was perform in the next IVF cycle with the same patients, we could successfully fertilize the oocytes (37%; p<0.001), thus achieving pregnancy and delivery. When the sperm were cocultured in medium containing ASA, there were binding of ASA to sperm surface. In addition, the mean rate of the acrosomal reaction in an in vitro acrosome reaction test was lower for Ab-bound sperm (43.5%) than for Ab-free sperm group (51.3%, p<0.05). We used human sperm and hamster oocytes to confirm the negative effects of the ASA on fertilization. The sperm and/or oocytes have been expose to medium containing ASA before IVF and ICSI. In this experiment, the ASA was bound to the oocyte and sperm surface. The following results were obtain by using various combinations of ASA free or ASA bound sperm with ASA free or ASA bound oocytes for IVF. When ASA free sperm were inseminate with ASA free and ASA bound hamster oocytes, the fertilization rates are 89.6% and 74.3% respectively. However, when ASA bound human sperm were use the results were 62.5% and 55.6% respectively. These shows the fertilization rate was significantly decreased in both ASA bound and ASA free oocytes when using ASA bound sperm. No difference found when ASA are present on the oocyte surface. When the hamster oocytes was treated by ICSI with ASA free or ASA bound human spermatozoa, no significant difference was found. These results showed that ICSI is the most promising method for couples who fertilization was not possible by conventional IVF because of ASA.
