김세종,박병란,김병근,Kim, Se-Jong,Park, Byeong-Ran,Kim, Byeong-Geun 대한영상의학회 2002 대한영상의학회지 Vol.46 No.4

목적: 3차원 전산화단층촬영을 이용해 한국인 경상돌기의 정상크기를 알아보고자 하였다. 대상과 방법: 경부나 측두골 CT를 시행한 115명의 환자를 대상으로 하여 3차원 재구성 영상과관상단면이나 축상단면을 이용하여 좌우 각각의 경상돌기의 길이, 모양, 첨단의 위치, 경상설골인대의 석회화를 후향적으로 분석하였다. 결과: 경상돌기의 평균길이는 우측이 26.6($\pm$7.9)mm, 좌측이 26.4($\pm$8.3)mm로 통계적으로 유의한 차이는 없었다(p=0.694). 성별 평균길이도 남자가 26.2($\pm$8.5)mm, 여자가 26.7($\pm$ 7.2)mm로 통계적으로 유의한 차이는 없었다(p=0.733). 연령별 평균길이는 20대까지는 증가 하는 경향을 보이나 그 이후로는 연령별 차이는 없었다. 경상돌기의 모양은 분절형(104/230, 45.2%)과 단절형(73/230,31.7%)이 많았고 곤봉형 첨단(74/230,32.1%)보다 체감형 첨단 (156/230,67.9%)이 많았다. 굴절형을 보인 경우는 6예(2.6%)이었다. 경상돌기의 첨단의 위 치는 내경동맥과 외경동맥사이에 있는 경우(211/230,91.7%)가 좀 더 내측에 위치한 경우 (19/230,8.3%)에 비해 월등히 많았다. 첨단의 위치에 따른 경상돌기의 길이는 내경동맥과 외 경동맥사이에 위치하는 경우 26.2($\pm$7.2)mm, 좀더 내측에 위치하는 경우 37.0($\pm$6.0)mm를 보여 통계학적인 의의가 있는 것으로 나타났다(p=0.000). 경상설골인대의 석회화는 33예 (14.3%)에서 보였다. 결론: 경상돌기의 길이는 18-32 mm이며 좌우 길이나 성별 차이는 없었다. 연령별로는 20대 까지는 증가하는 경향을 보이나 그 이후 연령별 차이는 없었다. 경상돌기의 첨단의 위치는 내경동맥과 외경동맥사이에 있는 경우가 대부분이었으며, 내경동맥과 외경동맥의 내측에 위치한경우가 그 사이에 있는 경우보다 경상돌기의 길이가 길었다. Purpose: To measure the normal size of the styloid process using 3D (three-dimensional) reconstruction CT. Materials and Methods: We retrospectively analyzed 3D reconstruction images obtained after coronal and axial CT scanning of the temporal bone or neck of 115 patients. The length and shape of both sides of the styloid process, the location of its tip, and calcification of the stylohyoid ligament were retrospectively analysed. Results: The mean length of the styloid process was 26.6 ($\pm$7.9)mm on the right side, and 26.4($\pm$8.3)mm on the left, a statistically insignificant difference (p=0.694). Its mean length was 26.2 ($\pm$8.5)mm in men and 26.7 ($\pm$7.2)mm in women, a statically in significant difference (p=0.733). As for variation with age, mean length tended to increase until the third decade, but not beyond. Segmental type (104/230, 45.2%) and fragmental type (73/230, 31.7%) were more commonly seen in shape of styloid process, and tapering tip of styloid process (156/230, 67.9%) is more commonly seen than clubbing tip of it (74/230, 32.1%). The process was angulated in six cases (2.6%); its tip was more frequently located between the internal and external carotid artery (211 cases, 91.7%) than more medially (19 cases, 8.3%). In the former location, the length of the process was 26.2($\pm$ 7.2)mm, and in the latter, 37.0($\pm$6.0)mm. The difference was statistically significant (p=0.000). Calcification had occurred in 33 cases (14.3%). Conclusion: The length of a normal styloid process was 18-32 mm. There were no statistically significant differences between its two sides, or between the sexes. Length tended to increase until the third decade, but not beyond. Predominantly the tip was located between the internal and external carotid artery, though the process was longer when its tip was located medially.

무당벌레 소화기관으로부터 단백질 분해 우수세균 6균주를 분리하였다. 단백질 분해세균의 16S rRNA 유전자 염기서열을 해석하여 계통학적 특성을 검토한 결과, Staphylococcus sciuri subsp. sciuri (3균주), Bacillus subtilis (1균주), Bacillus thuringiensis (2균주)로 확인되었다. 이들 균주 중 pH 5.0 배지에서 58.5 U/ml의 높은 효소 활성을 나타내는 Staphylococcus sp. CB2-3을 최종 선발하였다. 효소의 특성을 조사한 결과, pH 4.0-6.0에서 높은 활성을 나타내어 산성 단백질 분해효소임이 확인되었다. 효소의 최적 반응 온도는 $40^{\circ}C$ 이었으며, $30-50^{\circ}C$의 범위에서 80% 이상의 효소 활성을 유지하였다. Staphylococcus sp. CB2-3 균주의 생육과 효소 활성을 위한 최적의 배지성분을 조사하였다. 탄소원으로 0.5% 솔비톨을 첨가하였을 때 효소 활성이 2배로 증가되었으며, 질소원으로 0.5% 탈지유를 첨가한 경우 효소 활성이 2.5배 증가되는 것으로 나타났다. 무기염류로는 KCl, $K_2HPO_4$, $FeSO_4$를 첨가하였을 때 효소 활성이 가장 높은 반면에 2가 금속이온인 $Co^{2+}$, $Zn^{2+}$, $Mn^{2+}$, $Cu^{2+}$를 첨가하였을 때는 균의 성장과 효소 활성이 심하게 저해되는 것으로 나타났다. Six protein-degrading bacteria were isolated from digestive organ of Harmonia axyridis. These isolates were categorized as Staphylococcus sciuri subsp. sciuri (3 strains), Bacillus subtilis (1 strain), and Bacillus thuringiensis (2 strains) by 16S rRNA gene sequence analysis. The Staphylococcus sp. CB2-3 was selected as a protease-producing bacterium which showed the highest protease activity of 58.5 U/ml at the pH 5.0 medium. The optimal pH and temperature of protease activity were pH 5.0 and $40^{\circ}C$, respectively. This acid protease had a relatively high stability of 80% between $30-50^{\circ}C$ at broad temperature range. The opimal medium compositions of carbon, nitrogen and mineral source for cell growth and protease activity were investigated. When sorbitol (0.5%) was used as carbon source, enzyme activity was increased about 2 times than that of the basal medium. When skim milk (0.5%) was used as nitrogen source, activity was increased about 2.5 times than that of the control. Cell growth and enzyme activity were increased by mineral source such as KCl, $K_2HPO_4$, $FeSO_4$, but was completely inhibited by divalent ions such as $Co^{2+}$, $Zn^{2+}$, $Mn^{2+}$, $Cu^{2+}$.

본 연구에서는 비철제련의 공정 부산물에서 얻어진 Bi-Pb-Sb 3원계 합금 용탕의 산화반응에 따른 Sb과 Pb의 제거거동에 대하여 조사하였다. $N_2+O_2$ 가스를 침지 노즐을 통해 1173 K의 합금 용탕 중에 취입하여 Sb을 산화물과 금속상의 혼합물로 분리 회수할 수 있었다. 그리고 923 K의 Bi-Pb 2원계 용탕에 $N_2+O_2$ 가스를 취입하면 Pb가 산화되어 슬래그상으로 제거될 수 있으나, Bi도 동시에 산화되어 Bi를 정제할 수 없었다. In this study, behaviors of removing Sb and Pb by oxidation of molten Bi-Pb-Sb alloy which is a by-product of non-ferrous smelting process was investigated. The molten alloy was oxidized at 1173 K by bubbling $N_2+O_2$ gas through a submerged nozzle. The Sb was removed and recovered as mixed phase of $Sb_2O_3$ and metal Sb. In the case of bubbling $N_2+O_2$ gas into molten Bi-Pb alloy at 923 K, Pb was oxidized and removed to slag. But Bi could not be refined due to simultaneous oxidization of Bi with Pb.

김세종,김상덕,Se Jong Kim,Sang Duck Kim 대한안과학회 2007 대한안과학회지 Vol.48 No.9

Purpose: To evaluate the surgical results of endonasal dacrocystorhinostomy with two silicone intubation in common canalicular obstruction. Methods: Forty patients (57 eyes) who complained of tearing due to common canalicular obstruction underwent endonasal dacryocystorhinostomy. In this study, We randomly divided patients into two groups. One group underwent one-silicone tube intubation (29 eyes, group A) and the other group underwent two-silicone tube intubation (28 eyes, group B). After surgery, we compared the success rates and the causes of surgical failure between the two groups. Results: There were no significant differences between the two groups with regard to age, sex, duration of silicone intubation, or follow-up time. The primary success rates of the group A and the group B were 65.5% (19/29) and 85.7% (24/28) [(P=0.078)], respectively. the final success rates after the revisional surgery were 76.4% (21/29) and 92.8% (26/28) [(P=0.043)] respectively. Primary causes of surgical failure in the group A were: membranous obstruction of the internal ostium (6), common canalicular re-obstruction (2), sump syndrome (1), and functional obstruction (1). The main causes of surgical failure in the group B were: membranous obstruction of the internal ostium (2), and granuloma formation (2). Conclusions: We believe that endonasal dacryocystorhinostomy with two-silicone tube intubation might be an excellent alternative treatment modality in order to improve success rates in common canalicular obstruction.

As a result of conducting a cultural experiment of tomato using chicken feather protein hydrolysate (CPH) which was mass produced by keratin protein degrading bacterium Chryseobacterium sp. FBF-7 (KACC 91463P), we found that the stem and the root of tomato showed significant improvement in growth. For the purpose of phylogenic interpretation, a comparison was drawn between the effect of CPH, a treated CPH and untreated, on the changes of bacterial populations by 454 pyrosequencing based on 16S rRNA gene sequences. Tomato rhizosphere soil untreated with CPH (NCPH) showed 6.54 Shannon index from 3,281 sequence reads, and the rhizosphere soil treated with CPH (TCPH) showed 6.33 Shannon index from 2,167 sequence reads, displaying that it does not affect the diversity. Bacterial populations were composed of 19 phyla in the rhizosphere soil, and the phylum Proteobacteria occupied 40% of total bacterial populations. Bradyrhizobium, Agromonas, Nitrobacter, and Afipia (BANA group) which belong to Bradyrhizobiaceae were abundant and commonly detected in both the treated and untreated soils, suggesting the dominance of bacterial group in rhizosphere soil. The results obtained showed that CPH treatment does not affect the indigenous bacterial populations present in the rhizosphere soil. 케라틴 단백질 분해 세균 Chryseobacterium sp. FBF-7(KACC 91463P)을 이용하여 대량생산한 닭우모 단백질 가수분해물(CPH)을 토마토에 처리한 결과, 토마토 줄기와 뿌리의 생장이 현저하게 증가되었다. 닭우모 가수분해물을 처리한 토마토 근권토양 내 세균군집 변동에 대한 계통학적 해석을 위하여 16S rRNA 유전자 서열을 기반으로 454 pyrosequencing을 수행하였다. 가수분해물을 처리하지 않은 토마토 근권토양(NCPH)의 16S rRNA 유전자 염기서열(3,281 reads)과 가수분해물을 처리한 토마토 근권토양(TCPH)의 16S rRNA 유전자 염기서열(2,167 reads)은 각각 6.33과 6.54의 다양성 지수를 나타내어 세균군집의 다양성에는 영향을 미치지 않는 것으로 확인되었다. 각 토마토 근권토양에는 총 19개의 문(phyla)의 세균이 존재하였고, 이중의 약 40%가 Proteobacteria이었다. Proteobacteria의 Bradyrhizobiaceae에 속하는 Bradyrhizobium, Agromonas, Nitrobacter 그리고 Afipia (BANA group)는 NCPH와 TCPH의 모든 근권토양에서 우점을 이루어 닭우모 가수분해믈 처리에 의해 토양 토착세균 군집에 영향을 미치지 않는 것으로 확인되었다.
