Xiamen Univ, Coll Mat, Dept Mat Sci & Engn, Xiamen 361005, Peoples R China 电子邮件地址: [email protected] have reported all interesting method, named reverse breath figure, for the preparation of polymeric microsphere patterns. By the same procedure as breath figure, instead of under a humid atmosphere, linear and star-shaped poly(styrene-block-butadiene) copolymers dissolved in solvents such as toluene, trichloroform, and dichloromethane were cast onto the surface of a glass substrate in methanol or ethanol vapor. After the complete evaporation of the solvent, microspheres with the diameters ranging from hundreds of nanometers to several micrometers were prepared. The microsphere patterns are the reverse of the honeycomb porous structure of breath Figure. The mechanism of the microsphere formation has been studied to show that when the surface tension of the polymer solution is 1.5 mN/m higher than that of the condensed liquid, microsphere patterns call be prepared, whereas a honeycomb porous film of breath Figure call be obtained when the Surface tension of the polymer solution is lower than that of the condensed liquid. The viscosity of the polymer solution is also an important factor to influence the fabrication of the microsphere patterns.National Natural Science Foundation of China 2084400

NOSOLOGICAL DATA ON OUTPATIENTS AND INPATIENTS IN THE DEPARTMENT OF PSYCHIATRIC SERVICE AT NARA MEDICAL UNIVERSITY HOSPITAL IN FISCAL 1999

Nosologlcal data on outpatients and inpatients in the Psychiatric Service of Nara Medical University Hospital in fiscal 1999, are reported in this paper. There were 967 outpatient cases and inpatients were 232 inpatient cases. According to the diagnostic classification using F codes of the ICD-10, F4 (neurotic, stress-related and somatoform disorder) was most frequent (255 cases, 27％) in the outpatients, followed by F3 (mood disorder; 221 cases, 23％), F0 (organic, including symptomatic, mental disorder; 135 cases, 14％) and others. On the other hand, F2 (schizophrenia schizotypal and delusional disorder) was most frequent (69 cases, 30％) in the inpatients, followed by F4 (neurotic, stress-related and somatoform disorder; 51 cases, 22％), F3 (mood disorder; 38 cases, 16％) and others

CLINICAL INVESTIGATION OF CHARACTERISTICS OF EMERGENCY TELEPHONE COUNSELING AND MEDICAL SERVICE FOR OUTPATIENTS IN THE DEPARTMENT OF PSYCHIATRY, NARA MEDICAL UNIVERSITY, IN FISCAL 2004

Characteristics of emergency telephone counseling and medical service for outpatients in the Psychiatric Service of Nara Medical University in fiscal 2004 were investigated, and those clinical features of emergency psychiatric service of the core general hospitals in Nara Prefecture were analyzed. The total of emergency telephone counseling was 1,049 cases/year and the details consisted of mild psychiatric deterioration (31.8%), questions conceming medication (15%), and distress (of patient or caregiver) (12.8%). The majority of our responses needed for telephone counseling was brief supportive counseling (87.2%). According to the diagnostic classification of ICD-10, F2 (schizophrenia, schizotypal and delusional disorder) were most frequent (35.6%), followed by F4 (neurotic, stress-related and somatoform disorder; 23.5%), F3 (mood disorder; 19.2%), and others. The total of emergency medical services was 846 cases/year and the details consisted of psychiatric deterioration (anxiety, agitation, etc.) (36.8%), complaints related to physical symptoms (21.3%), and suicide attempts (11.7%). About 22% patients were referred for psychiatric examination from other departments in our hospital. Complaints related to physical symptoms might be one of psychiatric symptoms, but additional physical examinations (blood test, brain CT, etc.) were needed according to the circumstances for differential diagnosis of physical disease. The rate of suicide attempts was 11.7%, which may reflect the feature of a general hospital with psychiatric service. Also the availability of psychiatric service in general hospitals (21.7%) is more useful for them and consultation-liaison psychiatry is much important for one another
