Objective : Our purpose of this study was to determine the clarity and consuming time of fetal surface screening in thirty-eight fetuses from 24 to 32 weeks of gestation by use of two and three-dimensional ultrasonography. Methods : From May 1998 to July 1998, we performed the fetal surface screening of the fetal face, extremities, and spine. Thirty-eight fetuses of 24-32 weeks of gestation (thirty-seven normal fetuses and one abnormal fetus) were studied by use two-dimensional (AI 5200S, 3.5-5.0MHz; Acoustic Imaging Technologic Cooperation, U.S.A.) and three-dimensional ultrasonography (Volusion 530D, 3.5-5.0 MHz ; Kretz-Medicine, Korea). On the fetal face, we evaluated both orbits, nose, lips and brow. Both hands and feet, five digits and toes should be seen in this study. We evaluated cervical spine and lumbosacral junction of the spine. Results : The maternal average age of 38 patients was 29.9 years and the average gestational age was 29.7 weeks. The results of fetal surface screening were as follows : face (both orbits 89.5%, lips 92.1%, nose 92.1%, and brow 89.5%), extremities (both hands 68.4% and feet 73.7%), and spine (cervical spine 94.7% and lumbosacral junction 97.4%) by use of two-dimensional ultrasonography. By use of three-dimensional ultrasonography, results were as follows : face (both orbits 76.3%, lips 81.6%, nose 81.6%, and brow 78.9%), extremities (both hands 76.3% and feet 78.9%), and spine (cervical spine 71.1% and lumbosacral junction 73.7%). Consuming time for two-dimensional ultrasonography were 4.7 minutes for face, 11.6 minutes for extremities, and 5.7 minutes for spine. Using three-dimensional ultrasonography results were 12.8 minutes for face, 17.9 minutes for extremities, and 11.7 minutes for spine. Average consuming time of all fetal anatomic screening was 22.0 and 42.4 minutes by use of two and three dimensional ultrasonography. In one abnormal fetus had cleft lip and polydactyly of right foot which were detected all by three-dimensional ultrasonography, but we couldn't detect the polydactyly by two-dimensional ultrasonography. Conclusion : Three-dimensional ultrasonography was more time-consuming method, but we suggested that three-dimensional ultrasonography was superior than two-dimensional ultrasonography in fetal surface screening.

안묘순,송형근,박범수,한헌석,하태선 충북대학교 의과대학 충북대학교 의학연구소 1993 忠北醫大學術誌 Vol.3 No.1

Castleman 질환은 주로 종격동 임파선을 침범하여 임상적, 조직학적으로 흉성종과 유사한 소견을 보이는 질환이다. 보통 침범된 임파선은 3cm에서 7cm의 크기를 보이며 경계가 뚜렷한 종양으로 나타난다. 조직학적 소견상 hyaline-vascular형(H-V형)과 plasma cell형의 두가지로 나눈다. 임상적으로는 hyaline-vascular형은 별증상이 없으며 보통 우연히 발견되고 드물게 기도와 기관지를 압박하는 증세를 보이기도 한다. plasma cell형은 빈혈, 적혈구침강속도의 증가, 고감마글로불린혈증, 저알부민혈증, 그리고 저트란스페린혈증을 보이기도 한다. 저자들은 생후 2개월부터 반복되는 호흡기 감염과 거친 숨소리를 보이면서, 성장 및 발육장애를 보인 14개월된 남아에서, 기도에서 우측 주기관지까지를 압박하고 있는 종양을 흉부 전산화단층촬영에서 발견하고 떼어낸 후 조직소견상 hyaline-vascular형의 giant lymph node hyperplasia의 소견을 보이는 Castleman 질환 1례를 경험하였기에 보고하는 바이다. Castleman's disease(angiofollicular lymph node hyperplasia) can arise from lymph nodes or extranodal tissues and can be classified histologically into the hyaline-vascular form, characterized by hyaline follicle-like structures interspersed with vascular tissue, or the plasma cell variant, in which the follicle-like structures are seperated by sheets of plasma cells amidst vascular interfollicular tissue. The clinical manifestations of the multicentric variant can be protean and inculude fever, night sweats, weight loss, lymphadenopathy, hepatosplenomegaly, pleural effusion, ascites, anemia, thrombocytopenia, polyclonal hypergammaglobulinemia, and neurological and renal abnormalities. We report a case of Castleman's disease in 14-month old male patient with the chief complaints of recurrent respiratory symptoms and delayed growth and development, who was diagnosed as having a hyaline-vascular form of above disease after the excision of pulmonary mass which compressed the right main bronchus.

배지종류가 멜론의 생육 및 과실품질에 미치는 영향을 구명하고자 코리아멜론을 이용하여 시설내에서 재배하여 실험한 바 다음과 같은 결과를 얻었다. 토경, 펄라이트경 및 토양격리상에 재배한 경우 생육전반기에는 초장, 엽면적, 각 기관별 생체중 및 건물중 등에서 펄라이트경과 토양격리상이 토경 멜론보다 좋았다. 토양, 왕겨 혼합배지 및 토양·펄라이트·피트모스 혼합배지(360ℓ:180ℓ:60ℓ)에 재배한 경우 생육초기에는 왕겨 혼합배지와 토양·펄라이트·피트모스 혼합배지에서 조사전체 항목에 걸쳐 생육이 양호하였다. 토경, 펄라이트경 및 토양격리상에 재배한 멜론의 과실품질을 보면 과중은 토경보다 처리구가 높았고 당도는 펄라이트경에서 13.3도로 가장 높았다. 산도는 펄라이트경에서 낮게 나타났다. 토양에 왕겨, 펄라이트 및 피트모스를 혼합하여 재배한 멜론의 과실품질를 보면 토양·왕겨 혼합배지에서 당도가 12.4도로 가장 높았고 과중은 토양에 펄라이트와 피트모스를 혼합한 경우가 높았다. The experiment was carried out to investigate the effects of substrates on the growth and fruit quality of the Korea melon (Cucumis melo L. var. reticulatus). Seedlings were grown in soil(not isolated) and polyethylene boxes (10mX50cmX12cm, vol. 600l) filled with perlite, SI (isolated soil culture), RHS [rice hull (200l)+soil (400l)], SP-1 (soil : perlite : peatmoss = 360l : 180l : 60l), SP-2 (soil : perlite : peatmoss = 300l : 225l : 75l), respectively. Plant height, leaf area, fresh and dry weights were higher in perlite culture and isolated soil culture than those of soil culture at the beginning of growth. The vegetative growth of melon in RHS and SP-1 were better than that of soil culture. Soluble solid content and fruit fresh weight were higher in perlite and SI culture than those of soil culture. In the case of mixing substrates, soluble solid content was higher in SP-1 than that of the other substrates. The isolated soil culture of mixing perlite, peat, and soil were recommended as substrate for hydroponically grown melon.

Conformation with a hydrogen bond between the C_6 methoxyl and C_19 hydroxyl group among Diels-Alder adducts of thebaine and thebaine derivatives makes the molecule more rigid. To examine this hypothesis, new compound eliminated the intramolecular hydrogen bonding as a factor in determining the active conformation of the alkyl chain were available. A compound which the C_19 hydroxyl group has been replaced by a hydrogen has been synthesized as follows: Thevinone 3 has been prepared from thebaine by means of Diels-Alder reaction. Primary alcohol 7 has been prepared from Ketone 3 via epoxide 5 and aldehyde 6. This alcohol 7 underwent reaction with mesyl chloride to afford mesylate 8. Further reaction afforded 4, 5 α-epoxy-3, 6-dimethoxy-α-n-butyl-α, 17-dimethyl-6, 14-ethenomorphinan by displacement with propyl lithium cuprate.

본 연구는 perlite를 이용한 오이의 양액재배시 적정 배지량과 근권용적을 구명하고자 용기의 크기가 2, 4, 6, 8 및 10ℓ인 플라스틱 포트에 펄라이트를 채워 오이를 양액재배하였다. 근권용적이 증가할수록 초장, 경경, 엽수 및 엽면적이 증가하였고, 과실수와 과실중량에서는 근권용적이 큰 8ℓ와 10ℓ의 처리구에서 가장 양호하였으며 기형과 발생률도 낮은 경향이었다. 근권용적 6ℓ이상으로 하였을 때 경으로의 건물분배가 줄어들고 엽으로의 건물분배가 많았다. NAR과 CGR은 근권용적이 증가함에 따라 증가하는 경향을 보였다. 근권용적에 관계없이 본 실험 범위내에서는 LAI가 증가할수록 NAR과 CGR도 증가하는 경향을 나타내었다. This experiment was carried out to investigate the effect of container size and substrate volume on the growth and fruit yield of hydroponically grown cucumber(Cucumis sativus L.) plant. Seeds were sown in plug tray filled with coir dust on Feb. 13, 1998. Seedlings with 5 to 6 true leaves were transplanted in 2l, 4l, 6l, 8l and 10l plastic pots filled with perlite medium. Cucumber fruits were harvested with 1 to 2 day interval, and fresh weight, number and malform of fruit were recorded. Plant height, stem diameter, number of leaves and leaf area highly depended on the container size. Total fresh weight and the number of fruit were increased as the container size increased. NAR(net assimilation rate) and CGR(crop growth rate) increased with increasing the container size. Optimum container size for hydroponically grown cucumber plant using perlite medium was recommended as 8l per plant.

권순익,임동규,이상범,김계훈,고문환 한국환경농학회 2003 한국환경농학회지 Vol.22 No.2

국내에서 발생되는 하수오니에 대한 퇴비원료로의 활용성을 검토하기 위하여 전국 150개소의 하수처리장 중에서 82개소로부터 88점의 하수오니를 채취하여 중금속 함량을 분석하였다. 하수오니의 구분은 하수처리장이 위치한 지역의 인구를 기준으로 광역시(100만명 이상), 대도시(50만~100만명), 중소도시(10만~50만명) 및 농총지역(인구 10만명 이하 소도시 포함)으로 구분하여 몇 가지 중금속을 분석하고 현재의 퇴비원료 기준과 비교 검토하였다. 성분별 전국적인 분포는 As 0.0~54.3 mg/kg, Cd 1.7~197.3 mg/kg, Cr 7.3~2,854 mg/kg, Cu 87.4~5,730 mg/kg, Mn 129.3~10,289 mg/kg, Ni 20.1~2,057 mg/kg, Pb 7.6~197.5 mg/kg, Zn 523.5~6,349 mg/kg의 범위에 있었다. 퇴비원료기준과 비교하였을 때 As, Cd, Cr, Cu, Ni, Pb 및 Zn 중 어느 한 성분이라도 함량이 초과하는 비율은 광역시 및 대도시는 100%, 중소도시 95%, 농촌지역 93%로 나타났다. 중금속 성분별로는 전체시료 중 As는 1%, Cd 41%, Cr 15%, Cu 53%, Ni 47%, Pb 2% 및 Zn은 89%가 기준치를 초과하였다. The objective of this experiment was to investigate the possibility on agricultural use of municipal sewage sludge with respect to heavy metal contents in Korea. Metal contents (mg/kg) in 88 sludge samples were ranged from 0 to 54.3 for As, 1.7 to 197.3 for Cd, 7.3 to 2,854 for Cr, 87.4 to 5,730 for Cu, 129.3 to 10,289 for Mn, 20.1 to 2,057 for Ni, 7.6 to 197.5 for Pb, and 523.5 to 6,349 for Zn. Heavy metal contents of sludges were compared with the regulation on raw material for compost. All sludges produced from sewage treatment plants in metropolis (over a million in population) and large cities (500,000∼l,000,000) were not compatible with the regulation. In addition, 95% of sludge from small and mid-size cities (100,000∼500,000) and 93% from rural area (below l00,000) were not suitable. On the basis of Cd, Cu, Ni, and Zn contents, 41, 53, 47, and 89% of sludge samples were not compatible with the regulation on raw material for compost, respectively.

재배시스템과 pH가 양액재배 국화의 생장과 절화품질에 미치는 영향

정순주,이범선,박순기 충북대학교 한국과학재단 지정 첨단원예기술개발 연구센터 1998 연구보고서 Vol.3 No.-

본 연구는 양액재배를 이용한 국화의 절화재배시 적절한 재배시스템과 적정 pH수준 구명을 통한 고품질 절화국화의 다수와 생산기간을 단축을 목적으로 재배시스템의 종류와 pH변화가 국화의 생장과 절화품질에 미치는 영향을 구명하고자 실시하였다. 재배시스템은 분무경, 박막수경, 코코피트경 및 펄라이트경을 공시하였고, pH는 5.0, 5.5, 6.0, 6.5 및 7.0으로 처리하여 처리별 생장특성과 절화품질을 비교하였다. 생장 기간이 경과함에 따라 고형배지경인 코코피트경과 펄라이트경에서 자란 국화가 비고형배 지경인 분무경과 박막수경에서 자란 국화보다 초장, 경경, 엽수, 엽면적, 생체중 그리고 건물중 생장이 우수하였는데, 코코피트경에서 자란 절화국화가 특히 높았다. 박막수경에서 재배된 국화 뿌리는 근권의 산소부족, 온도와 pH의 변화 및 병해로 인해 뿌리가 갈변하고 로제트현상을 보였다. 고품질 절화국화는 코코피트를 이용한 고형배지에서 생산할 수 있었는데, 이는 다른 시스템에 비하여 근권온도, EC 및 pH 변화폭이 더 좁았으며 전 생육기간을 통해 보다 안정적이었다. pH변화에 따른 국화의 생장은 거의 차이가 없었지만, 초장을 pH 6.0에서 높았고 경경, 엽수, 엽면적, 생체중 그리고 건물중에서는 pH 6.5에서 높았으며, pH5.0일 때 가장 낮았다. 생육기간 동안 pH변화를 보면 pH 5.0과 pH 5.5에서는 조정한 이후 시간이 경과함에 따라 pH가 높아졌으며, pH 6.0은 변화폭이 적게 나타났으나, pH 6.5와 pH 7.0은 점점 감소하다가 다시 증가하였다. 본 실험의 결과로 보아 고품질 절화의 다수와 생산기간 단축을 기대하기 위해서는 코코피트경에서 pH는 6.0 내지 6.5로 관리하는 것이 적절한 것으로 확인되었다. This study was carried out to investigate the effect of hydroponic systems and pH change of nutrient solution on the growth and flower quality of cut chrysanthemum. Hydroponic systems were aeroponics and NFT as nonaggregate system and cocopeat culture, and perlite culture as aggregate system. pH was adjusted to 5.0, 5.5, 6.0, 6.5, and 7.0. Growth characteristics in terms of plant height, stem diameter, number of leaves, leaf area, fresh weight, and dry weight showed large differences among hydroponic system. Chrysanthemums grown on aggregate culture such as cocopeat and perlite culture system showed better growth than that of nonaggregate culture system such as aeroponics and NFT. Especially chrysanthemums grown on cocopeat culture system were the best of all the treated systems. High quality cut flower of chrysanthemum could be obtained in the cocopeat culture system due to the stabilization of root-zone environment such as EC, pH, and temperature. In the treatment of pH change, plant height was higher in the treatment with pH 6.0 but stem diameter, number of leaves, leaf area, fresh weight, and dry weight were higher in the treatment with pH 6.5. These results demonstrated that shortening of growth period and harvesting of high quality cut chrysanthemum could be obtained from cocopeat culture system with adjusting pH 6.0 to 6.5.
