Objective:This study tried to evaluate the validity of criteria for subgrouping inpatients alcoholics based primarily on age-at-onset factors. Method:We interviewed a selected group of inpatients (N=42). Subjects had a psychiatric interview, including completion of various alcohol drinking related questionnaires. Results:We found that there were differences between subgroups of alcoholics when divided according to Von Knorring’s age of onset criteria. The Type 2 early age of onset alcoholics (n=12) had a significantly higher percentage of positive family histories of alcoholism, (p<0.05), a higher percentage of past delinquent behavior (p<0.05), moree past delinquent behavior (p<0.05), more antisocial persanality trait(p<0.05) and a low score antisocial personality trait (p<0.05) and a low score of Quality of Life scale relative to the Type 1 late age of onset alcoholics (n=30). Conclusion:We concluded that there is validity to alcohol typology theory in relation to inpatients alcoholics and that age of onset is a useful defining criterion and other factor that family history, past delinquent history and antisocial personality trait are important factor to classify of alcohol subgroups.

To identify the effects of partial sleep deprivation on the sleep structure, the authors performed polysomnographic study for 9 healthy young adults. The subjects were college students, ranging in age from 20 to 25 years, without personal past or present histories of medical, neurological, or psychiatric illness and suffering from current sleep disturbance or parasomomnias. Sleep records were analyzed according to the criteria of Rechtschaffen and Kales' manual and tried paired t-test. The results were summarized as follows. 1. As for sleep parameters, total sleep time(TST), REM latency and REM duration were not changed significantly during deprivation period and recovery period compared with baseline. Sleep efficiency increased significantly during deprivation period and recovery period compaired with baseline, and sleep latency and WASO were shortened significantly during deprivation period and recovery period compared with baseline. 2. As for sleep structure, 1) The absolute value(minutes) of stage 1 decreased significantly during deprivation period and first recovery night compared with baseline, and the relative value(percentage) of stage 1 decreased significantly during deprivation period and recovery period compared with baseline. 2) The absolute value(minutes) of stage 2 decreased significantly during deprivation period compared with baseline, and the relative value(percentage) of stage 2 decreased significantly during deprivation period and first recovery night compared with baseline. 3) The absolute value(minutes) of slow wave sleep were not changed significantly during deprivation period and recovery period compared with baseline, and the relative value(percentage) of slow wave sleep increased significantly during recovery period compared with baseline. 4) The absolute value(minutes) of REM sleep decreased significantly during deprivation period compared with baseline, and the relative value(percentage) of REM sleep decreased significantly in the first deprivation night but, were not changed significantly during recovery period compared with baseline.

To identify the effect of total sleep deprivation on sleep structures, polysomnography was performed for 8 healthy young adults. The subjects were young adults, ranging in age from 21 years to 26 years, with no past or present histories of significant medical, neurological, or psychiatric illness as well as no current major sleep disturbances or parasomnias, After one adaptation night, each subject was recorded polysomnography in the sleep laboratory. Sleep records were analyzed according to the criteria of Rechtschaffen and Kales every 20 seconds, and tried paired-t-test. The results were summarized as follows. 1. After on night of total sleep deprivation, compared with the baseline WASO was significantly decreased in the first recovery night, and SWS and REM sleep were significantly increased in the first recovery night. 2. Compared with the baseline, the relative value(%) of REM sleep was significantly increased in the first recovery night. 3. Compared with the baseline, TST was significantly increased in the first recovery night, and sleep latency and REM latency were significantly decreased in the first recovery night. According to the above results we could identify the effects of total sleep deprivation on sleep structure in normal young adults.

Phenobarbital의 수면구조에 미치는 영향 : K-complex를 중심으로 Focused on the K-complex
이정규,왕성근 大韓神經精神醫學會 1993 신경정신의학 Vol.32 No.6
Polysomnographic(PSG) recordings were performed on 7 healthy male college students in the sleep laboratory of Chungnam National University Hospital in order to investigate the effects of phenobarbital on the sleep structure and K-complex, After being given a night in which to adapt to the laboratory environment, PSG were recorded and the findings were regarded as a baseline for each subjects. On the next night a PSG recording was taken after the intravenous administration of 100mg PB 20min before bedtime. Total sleep time, the percentage of each stage of sleep and the number of sptaneous K-complex which appeared in stage 2 wee compared before and after the PB administration. Total sleep time and total bed time were decreased statistically significant(p<0.05). Stage 2 sleep was increased statistically significant(p<0.05). The number of K-complex decreased after the administration, but not significantly. A significant positive correlation was observed between decreased number of K-complex and increased number of stage 2.
