Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP Patients who were treated with electroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain from stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from 7.7±1.7 to 4.4±2.0 with pain treatment(p<0.05). In accordance with improvement of pain scores, RS and MBI scores were also improved from 2.88±0.95 to 2.13± 1.01 and from 83.0± 16.9 to 94.7±9.5(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.

Sensitized photooxidation of carbaryl was carried out using persulfate ion, sulfate ion, nitrate ion, nitrite ion and chloride ion as sensitizers. Persulfate, nitrate, chloride and sulfate ions were proved to be effective to enhance the photooxidation of carbaryl. In the case of nitrite ion, however, no significant enhancement effect was observed. The sensitizing effect increased with increasing persulfate concentration, while nitrate ion showed the greatest sensitizing effect at 5㎎/l. When existed together with other ions, nitrite ion exhibited negative effect by scavenging the produced active hydroxyl radicals. It was also found that the rate of photo-oxidation of carbaryl in the presence of both the nitrate and persulfate was much faster than that in the presence of nitrate of persulfate singly.

Polymer-Impregnated Concrete(PIC) is a new polymer-concrete composite material which consists of basic cement concrete and polymer. The mechanical properties and behavior of PIC depend on the type of polymers and the impregnation techniques. In general, the polymer impregnation can improve the strength, durability and ductility of normal concrete. The objective of this study is to develop the analytical procedure for analyzing the structural responses of polymer-impregnated concrete flexural members with different polymer loading by using finite element method on the basis of experimental results.

This study was aimed to suggest to better treatment method of jaw cyst that the maximum diameter was wider than 3cm, using different treatment and clinical and radiographic result. We divided the 60 patients into three groups, group A(20 patients) were treated with cyst enucleation and Decalcified Freeze-Dried Allogeneic Bone(DFDB) graft, group B(20 patients) were treated with cyst enucleation and autogenous bone graft, group C(20 patients) were treated with only cyst enucleation. Each group was evaluated with panramic radiograph and clinical sign & symptom at pre-op and post-op(immediate, 6, 12, 24, 36 month). Bone density was evaluated with disital densitometer. The result was as follows : 1. Post-Op infection was higher in group C(4 pts.) than in group A(1 pt.) and B(1 pt.) 2. Post-Op gingival recession was higher in group C(3 Pts.) than in group A(1 pt.) and B(1 pt.) 3. Anatomic distortion was higher in group C(3 Pt.) than in group A(1 Pt.), and B(1 pt.) 4. reoperation was done in two patients who were in group C 5. There were donor site morbidity in two patients 6. there was no significant difference between group A and B in their bony density in their follow up period(p>0.05). 7. There were significant differences between group A, B and group C in their bony density until post-op 24 months but a little differences at post-op 36 months(P<0.01)

Sensitized photooxidation of aldrin was carried out using anions as sensitizers. Persulfate, nitrate ions were proved to be effective to enhance the photooxidation of aldrin. Nitrite ion was inhibited to the photooxidation of aldrin. In the case of sulfate and chloride ion, however, no significant enhancement effect was observed. The sensitizing effect increased with increasing persulfate and nitrate concentration. Nitrite ion was oxidated to nitrate by photolysis reaction. The sensitized effect decreased with increasing nitrite concentration.
이온화방사선에 의한 느타리버섯(Rleurotus ostreatus)의 ITS2 염기서열 변화

rDNA의 ITS2(internal transcribed spacer 2)부위에 대한 이온화방사선(gamma-ray)의 영향을 알아보기 위해서 감마선을 조사한 느타리버섯(Pleurotus ostreatus)의 5종의 변이중에서 ITS2의 염기서열을 결정하였다. ITS2의 염기서열은 1 kGy 조사군(PO-5, PO-6, PO-15와 PO-16)에서 변화되지 않았으나, 2kGy 조사군(PO-14)에서는 1개의 염기가 치환되었다. RAPD(ramdomly amplified polymorphic DNA) 양상에 의한 유전유사도의 변화가 다양하였고 섬유소성 고체검정 배지에서도 다양한 생장특성을 나타내었다. 본 연구결과는 ITS염기서열이 이온화 방사선에 의해 선량의존적으로 변화될 수 있음을 시사해 주었다.
