A study was conducted to confirm the changes of sleep parameters associated with aging and to investigate some differences of sleep parameters between healthy elderly persons and patients with dementia of Alzheimer's type. Polysomnography was done for 20 healthy elderly persons and 20 patients with DAT. The results were as follows: 1. With regard of sleep continuity variables, total sleep time(TST), waking after sleep onset(WASO), and sleep efficiency(SE) showed no statistically significant difference between two groups. However, sleep latency(SL) was prolonged and number of awakening during sleep period were significantly greater in DAT group than healthy groups(p<.0l, p<.05 respectively). 2. The ratio of each sleep stage to total bed time(TBT) or total sleep time(TST) showed no significant difference between two groups. 3. Total rapid eye movement(REM) density as well as REM activity were significantly lower in DAT(p<.0l), but REM latency showed no difference between two groups. 4. Aging was associated with shortened total sleep time, increased WASO, and decreased sleep efficiency. Some of the sleep continuity and sleep architecture parameters showed gender differences, and elderly women seemed to have better sleep quality. Any correlation between seventy of cognitive impairment and sleep parameters was not found.

지익성,김영희,신석철,왕성근,신윤오,이선우,김정란 충남대학교 의학연구소 2001 충남의대잡지 Vol.28 No.2

In order to assess the efficacy and safety of clozapine, 50 in-patients with treatment-resistanat schizophrenia were evaluated using PANSS(Positive and Negative Symptome Scale for Schizophrenia), CGI(Clinical Global Impression), AMS(Abnormal Involuntary Movement Scale), Adverse Event-Somatic Symptoms, Neurological Rating Scale for EPS before and during treatment. Mean daily dosage of clozapine was 344.15±123.43mg at 12th week. A clinically significant improvement in positive, negative, and general psychopathology was noted as early as week 2 through 12 week. The tolerability of clozapine was generally found to be good. Drowsiness/sleepiness, Hypersalivation, and Constipation were the most common side effects. There was no neutropenia, and 3 patients suffered from seizures. These results suggest that clozapine is worth considering for the treatment-resistant patients

The Influence of a Second Metal on the Ni/SiC Catalyst for the Methanation of Syngas

( Lan Lan Song ),( Yue Yu ),( Xiao Xiao Wang ),( Guoq Jang Jin ),( Ying Yong Wang ),( Xiang Yun Guo ) 한국화학공학회 2014 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.52 No.5

The catalytic performance of silicon carbide supported nickel catalysts modified with or without secondmetal (Co, Cu and Zn) for the methanation of CO has been investigated in a fixed-bed reactor using a feed consisting of25% CO and 75% H2 without any diluent gas. It has been found that the introduction of Co species can clearly improvethe catalytic activity of Ni/SiC catalyst, whereas the addition of Cu or Zn can result in a significant decrease in the catalyticactivity. The characterizations by means of XRD, TEM, XPS, CO-TPD and H2-TPR indicate that the addition ofCo could decrease the particle size of active metal, increase active sites on the surface of methanation catalyst, improvethe chemisorption of CO and enhance the reducibility of methanation catalysts. Additionally, the special interaction betweenCo species and Ni species is likely favorable for the dissociation of adsorbed CO on the surface of catalyst, and this mayalso contribute to the high activity of 5Co-Ni/SiC catalyst for CO methanation reaction. For 5Cu-Ni/SiC catalyst and 5Zn-Ni/SiC catalyst, Cu and Zn species could cover partial nickel particles and decrease the chemisorption amount of CO. These could be responsible for the low methanation activity. In addition, a 150h stability test under 2 MPa and 300 oCshowed that 5Co-Ni/SiC catalyst was very stable for CO methanation reaction.
