田珍淑,張煥一,李成柱 大韓神經精神醫學會 1985 신경정신의학 Vol.24 No.1

The 25 patients, in whom paranoid symptoms had occurred after age 45, and who had been admitted to Kyung Hee University Hospital from May 1979 to June 1984, were compared with 40 paranoid schizophrenics who had fitted to the DSM-Ⅲ diagnostic criteria, to clarify whether such syndrome should be classified to schizophrenia or a separate entity. The results were as following; 1. The male to female ratio was 0.92:1 in late paraphrenics, in contrast with 2.33:1 in control (p>0.05). 2. The age at onset was 53.6±8.0 year in late paraphrenics, in contrast with 28.1±7.6 year in control (p<0.001). 3. Majority of late paraphrenics had been ill for 2 weeks to below 6 months (48.0%), while for above 2 years in control (60.0%) (p<0.0005). 4. The late paraphrenics had been in hospital for 32.1±18.6 days on the average, in contrast with 53.4±31.3 days (p<0.01). 5. At time of admission, majority of late paraphrenics had married (68.0%) (p<0.005), in contrast with being single in control (62.5%) (p<0.0005). But divorced, separated or deceased were more in late paraphrenics (32.0%) than control (p<0.05). 6. The numbers of children of late paraphrenics were 3.8±2.0, and of control 0.8±1.4 (p<0.001). 7. Upon socioesonomic classes, majority of both patients belonged to middle class (p>0.5), and control (42.5%) belonged to lower class more than late paraphrenics (20.0%) (p>0.05). 8. The control had been admitted more frequently (2.9±2.1 times) than late paraphrenics (1.4±0.9 times) (p<0.01). 9. Both patients had schizophrenic family members most of all (each other 12.0% and 7.5%) (p>0.5), the late paraphrenics had somewhat more paranoid disorder (8.0%) than control (2.5%) (p>0.3). 10. Majority of late paraphrenics had paranoid personality trait (80.0%) (p<0.0005), in contrast with schizoid one in control (55.0%) (p<0.025). 11. Precipitating factors were present in 92.0% of late paraphrenics and 60.0% of control (p<0.01). Among the contents, family problem was most predominant (56.0%) (p<0.0005) in late paraphrenics and marital and financial problems (each other 28.0%) (p<0.05) in next order, while work (30.0%) and interpersonal problem (17.5%) were more prominent in control (p>0.5). 12. Among the contents of delusions, majority of both patients had persecutory ones (80.0%) (p>0.5) and idea of reference (each other 40.0% and 62.5%) (p>0.05). Otherwise, late paraphrenics had infidelity (36.0%) and hypochondriacal (32.0%) ones (p>0.05), while delusion of being controlled (55.0%) (p<0.01) and other Schneiderian ones (30.0%) were more common in control (p<0.05). In addition, affective symptoms (72.0%) (p<0.05) and cognitive difecit (40.0%) (p<0.0005) were more common in late paraphrenics, while hallucination (60.0%) (p>0.3) and loosening of association (67.5%) (p>0.05) in control. 13. The responses to physical treatment mainly composed of antipsychotics were fair (each other 92.0% and 100.0%) (p>0.05). Otherwise, late paraphrenics administered antidepressants (24.0%) more than the control (p<0.01), while electroconvulsive therapy was used more in control (20.0%) (p>0.1). 14. Most of the clinical diagnoses at discharge were established as paranoid disorder (56.0%) and in next order, paranoid schizophrenia (20.0%). Based on the above results, we concluded that late paraphrenia should be classified to paranoid disorder rather than atypical psychosis in addition to the agreement with the validity of separating this syndrome from schizophrenia in DSM-Ⅲ.

金昌煥,徐淑才 慶尙大學校 1986 論文集 Vol.25 No.2

Rhabditis sp.는 토양선충의 한 종류로 토양내의 유기물을 섭취하는 자유선충인데 광범위한 온도조건에서도 서식하고 있는 것으로 알려져 환경요소 중 온도가 Rhabditis sp.의 개체증식과 생장에 미치는 영향을 검토해 보고자 여러 온도 조건하에서 배양하여 개체의 생장과 증식수 및 대사작용에 관여하는 Esterase와 Acid phosphatase의 pattern 변화를 Electrophoresis를 통하여 조사한 바 다음과 같은 결과를 얻었다. 1. 20℃±4의 온도범위에서 배양된 Rhabditis sp.가 다른 12℃, 32℃ 온도하에서 배양된 Rhabditis sp.와 비교하여 증식수와 체형의 크기에 차이가 있었다. 2. Nanspecific esterase는 총 13개의 Isoenzyme band가 확인되었으며, 각 온도에 따라 12℃는 7개, 16℃·20℃·24℃는 각 6개, 28℃는 5개의 major band를 확인할 수 있었다. band 5번(Rf 0.58)은 전 온도범위에서 확인되었고 band 12번Rf 0.89)는 24℃온도에서만 확인되어 각 band에 따른 활성온도 범위가 각각 달랐다. 3. Acid phosphatase의 Isoenzyme pattern은 총 4개의 Isoenzyme major band 중 band 1. 2. 4. 번은 12℃에서만 major band이었고(Rf 0.14, 0.29, 0.33), band 3번(Rf 0.31)은 16℃ 이상의 온도에서 major band이었다. The present studies was carried out to investigate the influence of temperature on the rate of growth and on the multiplication of Rhabditis sp.. Rhabditis sp. was cultured at various temperature levels (12, 20, 24, and 28℃) and analysed by electrophoresis to investigated the isozyme pattern of nonspecific esterase and acid phosphatase. The results obtained were as follows. 1. Rhabditis sp. cultured at 20℃±4 showed differences in the rate of multiplication and body lengths, as compared with that at 12° or 32℃. 2. A total of 13 isoenzyme bands of nonspecific esterase was idendified and the numbers of major bands at esch temperature(12, 16, 20, 14 and 28℃) were 7, 6, 6, 6, and 5, respectively. Band 5 appeared at all temperatures tested, whereas band 12 appeared only at 24℃. 3. The patterns of acid phosphatase isoeozymes showed 4 major bands.. Out of 4 major bands band 1, 2 and 4 represented as major bands only at 12℃, whereas band 3 represented as major band at temperatures above 16℃. The results showed that the temperatures had effect on the activity of isoenzyme bands.

金昌煥,徐淑才,崔朱卿 慶尙大學校 1985 論文集 Vol.24 No.1

This study was carried out to investigate the migration and development of the Sparganum in rats and the changes of haematological values in the hosts infected with Sparganum. The results obtained were summarized as follows: 1. The recovery rate of the Sparganum in the infected rats was 57 per cent on the autopical findings of the infected individual rats during observations from 2 hours to 32 days after infection with Sparganum. 2. The larval Sparganum was found in the digestive tract within two hours after administration with oral route and then, the worms began to penetrate and migrate via the abdominal cavity within 4 to 6 hours and the worms were found in the muscular tissues 2 days onwards after infections. 3. The infected Sparganum began to deveolp the size of the body from 4 day after infection and then, the size of the Sparganum was measured by 52.9mm long and 3.2mm broad on 32 days after infection . 4. In the haematological observation of the host the red blood cell values changed little, while the white blood cells were increased significantly during 2 days after infection and thereafter they were recovered to the normal values.

This study was carried out to improve the dewatering characteristics of wastewater treatment sludge using Fenton's Reagent. The Fenton's Reagent consisting of FeSO_4 and H_2O_2 has powerful oxidizing ability and reactivity. According to the experimental results, primary dosage of FeSO_4 was more effective than secondary in the wastewater treatment sludge and the reagent was almost completed at about 20 minutes contact time with the wastewater sludge. The dosage ratio of FeSO_4:H_2O_2=1mole : 1.6mole was the highest dewatering efficiency. The specific resistance of Fenton's Reagent, 7.335×l0 exp (10)m/㎏, was much lower than these studied as 2.88×10 exp(14)m/㎏ of activated sludge and 1.05×10 exp(12)m/㎏ of conditioned digested sludge. Therefore, the Fenton's Reagent oxidized organics in and then improved dewatering of the wastewater treatment sludge.
