Cellulose was treated in sodium hydroxide under slack. X-ray and infrared spectra analyses was used to measure crystallinity of alkali treatment cellulose. In addition to that crease recovery was compared mutually, and breaking strength-elongation compared, too. X-ray diffraction showed partial recrystallization into cellulose Ⅱ lattic after slack treatment with sodium hydroxide. This reagents produced increased cotton elongation-at-break(breaking strength) with slack, and increased crease recovery.

Corydalis remota Fish. ex Max. (Papaveraceae) belonging to the Genera Corydalis is a well known medicinal plant mainly being used as a composotion of anagesic or anticonvulsive remedies of Oriental Medicine. Because the plant may vary depending on the environmental factors, it is reaconable to try plant tissue culture technology as an alternative and stable source of Corydalis aljaloids. In this study, five alkaloids were isolated from the cultures and they were characterized. The spectral data unambiguously trvealed that the isolated compounds were dihydrosanuinarine , protopine, tetrahy-dropalmatine, allocyptopine and ambinine, respectively.

Acanthamoeba spp. spread in soil, ponds, air and swimming pool, cause a granulomatous amoebic meningitis and amoebic keratitis in human and experimental animals. Their classification had depended upon morphological characteristics and physiological conditions such as thermophilic status and generation times. However, because amoeba species showed the morphological and physiological diversity in isolates, many attempts have been made on identification of Acanthamoeba spp. Restriction fragments length polymorphism (RFLP) analysis of IBS-small subunit ribosomal RNA (srRNA) was an useful tool for classification among morphologically and genetically closely-related species. In this study, 18S-srDNAs of amoebae were amplified by PCR with primer encoding 18S-srRNA gene and digested with restriction endonudeases, and RFLP analysis was applied on classification of Acanthamoeba Korean isolates (YM-4, YM-5 and YM-7), comparing with reference amoebae, A. culbertsoni, A. polyphaga and A. royreba. Trophozoites of six Acanthamoeba spp. had typical acanthopoda, but did not show any morphological differences. Cyst of Acanthamoeba sp. YM-7 was similar to that of A. polyphaga which was designated as group Ⅱ Acanthamoeba. Morphologically other amoebae belonged to group Ⅲ Acanthamoeba. Digestion of 18S-srDNA with six enzymes, Dde Ⅰ, Hae Ⅲ, Hind Ⅲ, EcoR Ⅰ, Rsa Ⅰ and Sph Ⅰ, resulted in various DNA fragments. Using the method of Nei and U (1979) for RFLP analysis, genetic divergence was not observed between A culbertsoni and Acanthamoeba sp. YM-4. Between A. culbertsoni and Acanthamoeba sp. YM-5, genetic distance was 0.070, 0.364 between Acanthamoeba sp. YM-4 and A. polyphaga, and 0.277 between Acanthamoeba sp. YM-7 and A. polyphaga. In comparison with A. culbertsoni and A. polyphaga, Acanthamoeba sp. YM-7 showed genetic distance of 0.330 and 0.154, respectively. Thus, Acanthamoeba sp. YM-7 is a similar species to A. polyphaga. Acanthamoeba sp. YM-5 is a different species from A. polyphaga, but closely-related to A. culbertsoni. Acanthamoeba sp. YM-4 can be classified as a subspecies or a strain of A. culbertsoni.

Background and Objectives: Lower urinary tract injuries in pelvic bone fracture can lead to significant complication. We tried to find out the relationship between the fracture location and the bladder, urethra injury in patients who sustaining pelvic bone fracture. We thought that the fracture locations could serves as markers for injury. Materials and Methods: A clinical study was made on 43 patients who sustaining pelvic bone fracture with bladder or urethra injury in the Chosun University hospital during the period of 5 years from January, 2002 to December 2006. Diagnosis was done by retrograde cystography, retrograde urethragraphy, abdomenpelvic computed tomography. Results: Of the 43 patients reviewed, 27 patients had intraperitoneal type bladder rupture, and 12 patients had extra-peritoneal type bladder rupture. 9 patients had urethral rupture. Intraperitoneal type bladder rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum. but the statistically significance is abscent (p= 0.642). Also extraperitoneal type bladder rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum. but the statistically significance is abscent (p= 0.548). And all type bladder rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum. but the statistically significance is abscent (p= 0.775). And urethral rupture cases are most commonly associated with infrapubic ramus, suprapubic ramus and acetabulum but the statistically significance is abscent (p= 0.528). Lastly, Combineded bladder rupture and urethral rupture cases are most commonly associated with infrapubic ramus, llium, Symphysis pubis. But the statistically significance is abscent (p= 0.462). Conclusions: In our study when there is a pelvic bone fracture, the fractured site of pelvic bone have no statistically association with lower urinary tract injury. But most common pelvic bone fracture site of all lower urinary tract injury cases is infrapubic ramus. Therefore, if infrapubic ramus fracture is found in the condition of pelvic bone fracture, it is highly likely to have lower urinary tract injury. More careful observation and diagnosis is necessary for this case.

In design practice welded connections represent the most commonly used connection typology due to their ability to reduce the relative rotation between the beam and the column allowing, in many cases, the simple modelling of the building structure as a continuous (i.e. rigid) frame. The prediction of the behavior of beam-to-column connections can be carried out by means of the component method which is largely applied in research studies. In the finite element analysis, the fillet of H-shaped steel, the welding property, and the effect of remained strain of welding were ignored to simplify the specimens in this study. The purpose of this paper is to analyze the initial stiffness of beam-to-column connections reinforced by welding in steel structures.

This paper presents an improved admission policy of 2000 academical year so that more promising students apply for the University. By analyzing the past admission data and the questioned report, a unique admission policy has been suggested as the University feature reflected. One of the major differences compared from the admission policy of the last year is that the entry number limit for the special admission is in creased or newly established such as the entry allocated for recommended students, perfectly attending students, and regionally apportioned students. Also established is the special admission for those licensed students and late educated students.

We investigated the effects of methanol extract of Fructus Chebula (MEFC) on local and systemic anaphylaxis. Passive cutaneous anaphylaxis inhibited to 61.42 12.8 % by oral administration of MEFC(I.0 glkg). MEFC inhibited compound 48/80-induced anaphylactic shock 100% with doses of 0.05-1.0 glkg . Administrations of MEFC (1.0 glkg) 60 min before, 5 min after, and 10 min after the compound 48/80 treatment were shown the mortality rates as 0%. MEFC (0.01-1.0 glkg) inhibited the histamine release significantly from the rat peritoneal mast cells by compound 48/80. These results indicate that MEFC inhibits mast cell mediated anaphylactic reactions by inhibition of mast cell degranulation in vivo and in vitro.

Purpose: We determined the use of scrotal ultrasonography in the initial diagnosis and management of testicular injuries due to blunt scrotal trauma. Mateiials and Methods: We reviewed 54 patients of scrotal trauma in the last 8 years. Forty patients were evaluated by ultrasonography preoperatively. A heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition was the basis for diagnosis of testicular rupture. Among them, 33 cases underwent scrotal exploration and 7 cases were managed conservatively. The remaining 14 patients were evaluated only by physical examination, 8 patients of them were explored immediately because of suspicious testicular mpture. The accuracy of ultrasonography were determined by comparing radiographic interpretations with intraoperative findings. Results: Among the 33 patients who were evaluated by ultrasonography and explored immediately, there were 26 suspected testicular ruptures on ultrasonography. Surgical exploration revealed testicular rupture in 23 and simple hematoma in 10. The testicular rupture was correctly diagnosed by ultrasonography in the 22 cases, and there were 4 false-positive and 1 false-negative diagnoses of testicular rupture. The sensivity and specificity for the diagnosis of testicular rupture are 96% and 60%, and the positive and negative predictive values are 85% and 86%, respectively, Conclusions: Scrotal ultrasonography, with the main radiographic finding of a heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition, is highly sensitive on the diagnosis of testicular rupture. And it increases the salvage rate for testicular rupture with preservation of the testicular function and prevents delayed complications of chronic pain, atrophy and orchiectomy associated with missed testicular rupture.

Objective : Acupuncture has been used for treatment of numerous disorders, especially for pain control in Oriental Medicine. However, the mechanism of pain control by acupuncture was not clear until now. This study was performed to prove analgesic mechanism of acupuncture treatment at acupoint ST_(36) by observing the changes of abdominal pain and c-Fos expression in the thalamus. Methods : Abdominal pain was induced by acetic acid, and the changes of writhing reflex after acupuncture treatment an ST_(36) and non-acupoints were measured. c-Fos immunohistochemistry was also performed to study the changes of the neuronal activity in the thalamus. Results : The writhing reflex decrease significantly after acupuncturing at ST_(36) compared with control group(p<0.05). The changes of the writhing reflex by non-acupoint acupuncture treatment also showed significant decrease compared with control group(p<0.05). c-Fos expression in the thalamus, especially periventricular part was significantly decreased after acupuncturing at ST_(36) compared with control groups(p<0.05). Conclusion : This study shows that the acupuncture has the analgesic effect in the abdominal pain induced by acetic acid and the thalamus might be a important area for this mechanism.
