서인수,홍재상 한국해양학회 2004 바다 Vol.9 No.3

인천 동춘동 척전 갯벌에 서식하는 대형 저서동물의 중요 우점종에 대한 시ㆍ공간적인 분포 패턴을 알아보기 위하여 1990년 9월부터 1992년 7월까지 2개년 동안 격월별로 현장조사를 실시하였다. 조사 기간 중, 총 111종, 25,491 개체가 채집되었고, Le Bris Index에 근거한 상위 15위의 우점종은 19,072개체의 밀도를 나타내 74.8%를 점유하였다. 백금갯지렁이과(Nephtyidae)의 다모류 3종과 칠게아과(Macrophthalminae)의 갑각류 2종은 동일한 속(genus)이 면서 조위와 퇴적상에 따라 뚜렷이 구분되는 서식처를 갖는 것으로 나타났다. 척전 갯벌의 중요 우점종은 다모류의 Heteromastus filiformis, 이매패류의 동죽(Mactra veneriformis), 맛조개(Solen strictus), 극피동물 해삼류의 가시닻해 삼(protankyra bidentata), 갑각류의 칠게(Macrophthalmus japonicus)등이었다. 5종의 중요 우점종에 대하여 공간에 따른 개체밀도를 비교한 결과, H. filiformis와 동죽은 통계적으로 유의한 차이가 없었으나(P>0.05), 맛조개, 칠게와 가시닻해삼은 유의한 차이가 있었다(p<0.001). 이것은 중요 우점종이 조위와 퇴적상에 따라 출현 개체밀도에서 공간적인 차이가 있음을 의미한다. H. flzyomis와 동죽은 조위와 퇴적상에 무관하게 갯벌의 전역에서 높은 밀도로 출현하였다. 그러나, 칠게는 펄이 많은 상부에서 밀도가 높았고, 맛조개, 가시닻해삼은 갯벌의 중ㆍ하부인 모래펄에서 우세한 밀도로 출현하여 이를 반영하고 있다. Spatio-temporal distribution patterns of the major dominant species were assessed from bimonthly monitoring of macrotidal flat in Cheokjeon, Incheon, Korea between September 1990 and July 1992. Overall, macrofauna comprised a total of 111 species, 25,491 inds.136 ㎡. The result of Le Bris index, dominance ranking of the lead-ing species showed that the top 15 species accounting for 74.8% (19,072 inds.) of total density. In Cheokjeon tidal flat, some species were especially habitat-restricted such as genus Nephtys (Annelids; Polychaetes) and Mac-rophthalmus (Crustaceans; Decapods). Based on the density data, the five dominant species were the polychaetes Het-eromastus filiformis, the bivalves Mactra veneriformis and Solen strictus, the brachyurans Macrophthalmus japonicus, the holothuriodeans Protankyra bidentata. The results of one-way ANOVA, mean value of H. filiformis and M. ven-eriformis did not show significant changes with tidal elevation and sediment composition (p>0.05). But, other species (S. strictus, M. japonicus and P. bidentata) showed significant variations (p<0.001). In conclusion, these indicate significant spatial fluctuation with tidal elevation and sediment characteristics in some species.

Cycloheximide가 膵臟腺房細胞에 미치는 影響에 關한 微細形態學的 硏究

徐仁壽,洪錫宰 慶北大學校 醫科大學 1980 慶北醫大誌 Vol.21 No.2

蛋白合成障碍가 膵臟腺房細胞의 微細構造 및 自家貪食力에 미치는 影響을 알아보기 爲해 흰쥐에 cycloheximide와 自家貪食亢進劑인 neutral red를 單獨 또 倂合 投與하여 惹起된 微細形態學的 變化를 電子顯微鏡으로 觀察하였던 바를 要約하면 다음과 같다. Cycloheximide는 膵臟腺房細胞에 比較的 初期에서부터 Golgi complex의 腫脹, ER膜에 附着된 ribosome의 脫落을 主로 한 輕한 變化를 일으켰다. 60分이 經過하면 ER 및 mitochondria의 輕한 腫脹, 脫落된 ribosome의 破壞 및 消失等을 볼 수 있었으나 그 程度는 輕微하였다. Autophagic vacuole의 計數는 對照群이 한 腺房當 10.1±2.2個, neutral red投與群이 54.4±4.9個, cycloheximide와 neutral red를 同時에 投與한 群에서는 21.5±4.1개, cycloheximide投與 30分 後 neutral red 投與群에서는 9.7±2.7個이었다. 이와 같은 事實은 cycloheximide가 autophagic vacuole形成에 抑制的 效果가 있다는 것을 意味하며 autophagic vacuole의 形成에는 어떤 形態로든 새로운 蛋白合成이 必要하다는 것을 示唆하는 것이라 생각된다. This study was carried out to investigate the effects of cycloheximide, known as an inhibitor of protein synthesis at the level of polypetide elongation, on the fine structures of pancreatic acinar cells. Also studied was the effects of protein synthesis inhibition by cycloheximide on the neutral red-induced autophagocytosis. Twenty-one male albino rats, maintained on water only for 12 hours, weighing 200㎎. in average, were divided into 5 groups, 3 rats for each groups except Group 2. Group 1: This is to serve as a control group. Two consecutive doses of 0.4㎖. of saline per 100 gm. of body weight were given intraperitoneally to 3 rats at interval of 30 minutes. Group 2: A dose of 2 mg. of cycloheximide per 100gm. of body weight was given to 9 rats intraperitoneally and 3 animals each were sacrificed 30, 60 and 90 minutes after injection, respectively. Group 3: A dose of 2mg. of neutral red per 100gm. of body weight was given to 3 rats intraperitoneally, 30 minutes after intraperitoneal injection of 0.4 ㎖ of saline per gm. of body weight. Group 4: A dose of 2㎎. of neutral red per 100gm. of body weight was given to 3 rats intraperitoneally, 30 minutes after intraperitioneal injection of 2㎎. of cycloheximide per 100gm. of body weight. Group 5: Simultaneous intraperitoneal injection of 2 ㎎. of neutral red and 2㎎. of cycloheximide per 100gm. of body weight was given to 3 rats. All animals were sacrificed 60 minutes after the the last injection except Group 2. Pancreas extirpated for both light and electron microscopic studies. The results were summarized as follow: Cycloheximide induced moderate dilatation of Golgi complex aad detachment of ribosomes from RER membrane from early stage (sacrificed 30 minute after injection). Mild swelling of RER and mitochondria along with destruction and disappearance of detached ribosomes were noted in the animals sacrificed 60 and 90 minutes after injection (Group 2). The number of autophagic vacules per acinus was 10.1±2.2 in the control group (Group 1); 54.4±4.9 in neutral red only group (Group 3); 21.5±4.1 in neutral red simultaneous with cycloheximide group(Group 5); 9.7±2.7 in the group with neutural red administered 30 minutes after cycloheximide injection(Group 4). The results showed marked inhibitory effects of cycloheximide on the neutral red-induced autophagocytosis, suggesting need for do novo synthesis of protein in the formation of the autophagic vacuoles.

This paper describes the scanning electron microscopic findings of smeared sputum cytology. The metaplastic squamous cells had relatively abundant cytoplasm. Their free surfaces were covered by complex network of regular microridges. The carcinoma cells had numerous irregular and irregulary spaces microvilli in their surfaces. Some cells had smooth or wrinkled surface with few or no microvilli.

본 연구에서는 흡수, 방사 및 비등방성 산란을 하는 축대칭 유한원통형매질에 서의 형식해로부터 Gaussian Quadrature를 이용하여 수치적으로 엄밀해를 구하고 P-1 과 P-3근사해법을 통하여 얻어진 해와 비교하여 P-1과 P-3근사해법의 타당성을 검토하 였다.또한 매질의 광학두께, 산란알베도, 벽면방사율, 형상계수 등을 주요 파라미 터로 하여 이들의 영향에 대하여 고찰하였다. An analysis of radiative heat transfer has been conducted on axisymmetric finite cylindrical media. It is assumed that the temperature in the media is uniformly distributed and the boundaries are diffusely emitting and reflecting at a constant temperature. The scattering phase function is represented by the delta-Eddington approximation to account for highly forward scattering by particulates just as in the combustion system. Exact numerical solutions are obtained by Gaussian quadrature method and compared with P-1 and P-3 approximation solutions to verify their engineering application limit. The effects of optical thickness, scattering albedo, wall emissivity and aspect ratio are investigated. The results show that P-3 approximation is found to be in good agreement with the exact solution.

In an effort to establish the role of new1y recognized as well as established agents of $lt;liarr- hca in Korean infants and children, 209 diarrheal children admitted to Hanyang University Hospital, Seoul, Korea, were evaluated during the course of 12 months. Stools were examined for Aeromonas hydrophila(Ah), Campylobacter jejuni(Cj), C.tostridium difficile(Cd), classic enteropathogenic E. cali(EPEC), enterotoxigenic E. coli(ETEC) and other enterotoxigenic gram-negative bacteria(GNB), enteroadherent E. coli(EAEC) and other Hep-2-adherent GNB, Salmonella, Shigella, and rotavirus(RV). One or more pathogens were identified in 70.3% of the children with diarrhea. RV was the most common pathogen, accounting for 51.2% of thecase, followed by ETEC(23.9%}, Cd(16.3%), EAEC(16.3%), EPEC(8.1%), heat-stable toxin-producing (ST') Klebsiella pneumoniae(1.9%), Hep-2-adherent K. pneumoniae(1.4%), ST^+ r1cinetobacter calcoaceticus var, anitratus(0.5%), Cj(G.5%), and Salmonella spp.(0.5%). Ah was never isolated. Multiple pathogens were commonly encountered, especially in those cases with either RV or ETEC infection. Forty-six(44.7%) of the 103 RV infections were associated with other potential pathogens. Of the 47 symptomatic cases infected with ETEC, 26(57.8%) were isolated with other pathogens.
