This experiments were carrid out to examine the effects of liquid medium addition in same vessels on shoot elongation and rooting, and soil survival of plantlets after the shoot cluster sections of Spathiphyllum floribundum 'Cupid' were pre-cultured. The shoot clusters with 3 to 4 small shoots were proliferated on LS medium supplemented with 2.0 mg/L BA for 8 weeks, and then 15 mL of various kinds of liquid medium was added in the same vessels. The addition of 15 mL liquid medium containing l/2 MS macro elements, 50 g/L sucrose and 5.0∼10.0 g/L activated charcoal was significantly stimulated the elongation and rooting of proliferated shoots. The medium addition was resulted in the enhanced soil survival of plantlets. Spathiphyllum을 기내에서 증식시킨 후, 액체배지를 첨가하여 신초의 생장 및 발근을 촉진시키고, 기외에서 순화율을 향상시켜 생산비를 감소시키기 위하여 일련의 실험을 실시하였다. 3∼4개의 신초를 가지고 있는 Spathiphyllum floribundum 'Cupid' 의 신초 cluster 절편체를 BA 2.0 mg/L가 첨가된 LS배지에서 8주간 증식시킨 후에 15 mL의 액체배지를 동일용기에 첨가하였다. 액체배지 첨가는 1/2 MS 다량요소+sucrose 50 g/L +활성탄 5.0∼10.0 g/L가 첨가된 배지 15 mL를 첨가하는 것이 식물체의 기내생장 및 발근에 양호하였으며, 온실에서 perlite와 vermiculite가 1 : 1로 혼합된 용토에 발근된 식물체를 재식하면 95% 이상 생존하였다.

To investigate the thyroid hormonal changes and their mechanisms in patients with chronic renal failure, we measured serum levels of the thyroid hormones using rediommunoassay and calculated each ratio of serum thyroid hormones in 20 patients with chronic renal failure who were on hemodialysis therapy. The following results were obtained. 1) The serum T_3 concentrations was significantly lower in patients with chronic renal failure(0.75±0.23㎍/l) than in normal subjects(1.18±0.37㎍/l). 2) The serum T_4 concentrations was significantly lower in patients with CRF(4.96±1.20㎍/l) than in normal subjects(8.45±1.55㎍/dl). 3) The serum FT_4 concentrations was significantly lower in patients with CRF(0.69±0.22ηg/ml) than in normal subjects(1.18±0.15ηg/ml). 4) The serum TSH concentrations in patients with CRF (2.08±2.38μμ/ml) tends to be greater than normal subjects(1.65±0.79μu/ml). But it was not significant statistically. 5) The serum rT_3 concentrations in patients with CRF (21.95±14.79ηg/ml) tends to be greater than normal subjects(18.5±2.80ηg/ml). But it was not significant statistically. 6) The calculated serum concentration ratios of T_3/T_4 and rT_3/T_3 in patients with CRF(0.17±0.09 and 38.30±43.31 : presented as Mean±SEM) dis not differ significantly that of normal subjects(0.14±0.04 and 17.04±5.71). But the serum concentration ratio of rT_3, T_3 in patients with CRF(4.53±2.73) was significantly greater than in normal subjects(2.25±0.50) 7) There was no significant difference in thyroid functions between male & female patients with CRF. 8) The serum T_3, T_4, TSH and rT_3 concentrations not related to the duration of hemodialysis, but serum FT_4 concentrations was lower in patients treated with hemodialysis for more than 36monts(0.49±0.10ηg/ml) than in patients treated with hemodialysis for less than 36months(0.74±0.22ηg/ml). It was concluded that the serum T_3, T_4 & FT_4 concentrations were significantly decreased, while calculated serum concentration ratios of rT_3/T_4 was significantly increased in patients with CRF. Thus we estimates that this decreased thyroid function in patients with CRF may reflect the alteration of serum rT_3 metabolism or increased peripheral conversion of T_4 to rT_3. It is also estimated that chronic hemodialysis leads to a propotional decline of thyroid hormone.

저자들은 1989년 12월부터 1991년 6월까지 1년 7개월 동안 동국대학교 포항병원 내과와, 1991년 11월부터 1992년 12월까지 1년 1개월간에 동국대학교 의과대학 경주병원 내과에 내원한 폐질환 환자 247명을 대상으로 굴곡성기관지내시경을 사용하여 검사한 바 다음과 같은 성적을 얻었다. 1) 기관지내시경술을 받은 247명의 환자중 폐암 59례, 폐결핵 및 기관지결핵 58례, 폐염 35례, 기관지염 33례, 우측중엽증후군 11례, 농흉 및 늑막염이 9례, 미만성간질성질환 6례, 기관지 확장 증 5례, 폐농양 4례 순이었다. 2) 총 59예의 폐암 환자중 기관지내시경상에서 이상소견을 보였던 50례중 조직학적으로 확진된 경우는 38례(64.4%)였다. 폐암의 조직학적 분류를 보면 편평상피암이 36례(61%)로 가장 많았고, 남녀비는 5 : 1이었으며 호발연령은 50∼60대가 가장 많았고 호발부위는 양쪽 상엽기관지였다. 3) 폐암을 제외한 다른 염증성 폐질환에서는 기관지염과 폐염에서의 기관지 내벽은 부종과 충혈을 내공은 정상소견을 보이고, 폐결핵과 기관지확장증에서는 벽은 부종, 충혈, 삼출액 및 출혈이 있었고 내공은 협착과 변형을 보였다. 이중 결핵성 병변을 보면 폐결핵이 40례, 기관지결핵이 18례였는데 객담의 항산균도말은 39.5% 양성이었고 항산균 배양은 50% 양성이었으며 조직생검으로는 31,3%가 진단되었다. It is well known that flexible fiberoptic bronchoscopic examination is one of the best available method for the diagnosis of various pulmonary diseases. For the assessment of diagnostic yield, we analyzed 247 patients of various pulmonary diseases who had taken flexible bronchofiberoscopy in the Department of Internal Medicine, DongGuk University Medical School for the 36 months from December, 1989 to December, 1992. The results are summarized as follows: 1. Final diagnosis of the 247 cases was classified as follows: lung cancer 59 cases, tuberculosis 58 cases, pneumonia 35 cases, bronchitis 33 cases, RML syndrome 11 cases, empyema and pleurisy 9 cases, diffuse interstitial lung disease 6 cases, bronchiectasis 5 cases and lung abscess 4 cases. 2. The classification of primary lung cancer confirmed histologically was squamous cell carcinoma 36 cases(61%), adenocarcinoma 5 cases(8.5%), small cell carcinoma 12 cases (20.3%), undifferentiated carcinoma 4 cases(6.8%) and unditermined carcinoma 2 cases(3.4%). 3. The diagnostic yield of fiberoptic bronchoscopy for lung cancer was 86.7% and the histological confirm rate was 64.4%. 4. In lung cancer cases, the most prevalent ages was 5th∼6th decades and male to female ratio 5 : 1, the localization of chest film, right(39 cases, 66.1%) was more than left(18 cases, 30.5%) and the most frequent site was right upper lung field(16 cases, 27.1%). 5. We could not differentiated the various inflammatory lung diseases by bronchofiberscopy only. But in the bronchofiberscopic examination of various inflammatory lung diseases, we observed the nature of the wall and lumen of bronchus resulting as follows : in bronchitis and pneumonia, the bronchial wall disclosed edema and hyperemia, and the bronchial lumen showed normal finding; in pulmonary tuberculosis and bronchiectasis, the bronchial wall showed edema, hyperemia, exudate, and the bronchial lumen revealed stenosis and deformity, especially luminal widening was a characteristic finding in bronchiectasis; Lung abscess had purulent discharge on the bronchial wall and showed normal lumen of the bronchus. 6. Of the total tuberculosis 58 cases, 40 cases were pulmonary tuberculosis and 18 cases were endobronchial tuberculosis. The tuberculosis was confirmed by sputum AFB smear in 39.5%, AFB culture in 50%, biopsy in 31.3%. In our country with higher prevalence rate of tuberculosis it is important to find out the cases with endobronchial tuberculosis early for prevention of permanent bronchial stenosis.

국 문 초 록폐쇄성 폐질환 환자에서 기도폐색의 가역성 유무는 기관지 천식과 만성 폐쇄성 폐질환을 구분하여 치료방향을 결정하는데 많은 도움을 주며 이러한 기도폐색의 가역성을 증명하기 위해 흡입 기관지 확장제에 대한 기류속도 증가를 평가하는 검사가 많이 이용되고 있으나 판정기준이 명확하지 않아 이 판정기준은 기관지 천식 환자와 만성 폐쇄성 폐질환 환자를 구분하는데 충분한 근거가 되지 못하여 왔다. 이러한 문제점들을 보완하기 위해 본 연구에서는 비교적 적합하다고 알려지고 있는 4가지 새로운 판정기준 즉, "Absolute", "%Initial", "%Predicted", "%Possible"를 가지고 기관지 확장제 흡입반응 검사를 시행한 528명을 3군(천식군, 만성 폐쇄성 폐질환군, 기타 질환군)으로 나누어 흡입 전 일초시 폐활량(FEV1)에 대한 의존성과, 기관지 천식과 만성 폐쇄성 폐질환을 구분하는 유용성에 대해 비교 분석해 보았다. 연구 결과 기관지 확장제 검사의 판정기준 중 "%Predicted"가 기관지 확장제 흡입 전 일초시 폐활량(FEV1)에 가장 비의존적이었으며 "%Initial"이 기관지 천식과 만성 폐쇄성 폐질환을 구분 짓는 유용한 지표임을 알 수 있었다.AbstractVarious indices are used to assesses the bronchodilator response in patients with obstructive airway disease. It is unclear, however, which index is most informative.The aim of this study was to compare four indices of the bronchdilator response and(1) to examine the independence of the prebronchodilator forced expiratory volume in one second(FEV1); (2) to distinguish asthma from chronic obstructive lung disease.528 patients with obstructive airway disease were studied. Patients were divided into 3 syndrome groups on the basis group of a standardized history and other laboratory tests; asthma(n=187), COPD(n=149), and others(n=192).FEV1 was measured before and 15 minutes after inhalation of 400 μg fenoterol.ΔFEV1 was expressed as a percentage of initial FEV1("%Initial"), absolute value("Absolute"), percentage of predicted FEV1("%Predicted"), and percentage of maximal possible increase("%Possible")."%Possible" was the most dependent on initial FEV1, and "%Predicted" was the least dependent on initial FEV1."%Initial" had the highest likelihood ratio(2.03) for separating the patients with asthma from those with chronic obstructive lung disease among all expression of bronchodilator response.

유체의 耐寒性 및 低 Glucosinolate 形質 改良

강광희,김재환,이예봉 영남대학교 자원문제연구소 1993 資源問題硏究 Vol.12 No.-

The purpose of this paper is to improve new lines of cold damage tolerance and low glucosinolate(GSL) content from four combination AX B, AX C, AX D and AXE. Domestic line A was tolerant to cold damage and high GSL(78.3 umol/g dry meal) , while introduced lines B, C, D and I were susceptible to winter cold and low GSL(13.6-31.3 umol/g dry meal)content. In F2 generation, the variance of cold damage tolerance and GSL content were not stable. Thus, it was possible to select some lines which had cold damage tolerance and low GSL content. From the field experiment, selected lines turned out to have tolerant winter hardiness and low GSL content less than 30 fmol/g dry meal, and other characteristics for yield were desirable. The new rapeseed varities which were selected by this procedure could be expanded to the higher latitude area.

송풍량 자동제어 방식이 적용된 Bio-drying 공정에서의 수분제거 특성 평가

최선봉,박재람,곽예봉,이동훈 한국폐기물자원순환학회 2016 한국폐기물자원순환학회 학술대회 Vol.2016 No.11

폐기물의 높은 수분함량은 폐기물 에너지화에 있어 효율을 저해시키는 주된 요인이다. 기계적・생물학적 처리(Mechanical Biological Treatment, MBT)는 생분해성 폐기물의 매립량을 줄이고, 고형연료 생산을 통한 에너지회수를 위해 적용된 기술이다. 최근에는 고품질의 고형연료를 생산하고자 MBT 시설에서 생물학적 처리공정으로 Bio-drying 공정을 적용하고 있다. 본 연구에서는 현재 가동중인 기계적 선별공정 중심의 생활폐기물 고형연료화 시설에서 배출되는 선별 잔재물을 대상으로 Bio-drying이 진행되는 과정에서의 수분제거 특성을 파악하였다. 또한, 특정 범위(45~50℃)로 배출가스의 온도가 유지될 수 있도록 송풍량 자동제어 방식을 적용하였으며, 단일방향의 공기공급에서 기인되는 수분함량의 불균질 분포를 해소하기 위해 송풍방향의 전환을 실시하였다. 2주 동안의 Bio-drying을 통해 폐기물의 40.3%이 감량되었으며, 초기 수분중량 대비 79.4%의 수분이 제거(건조)되었음을 확인하였고, Bio-drying 전/후 폐기물의 수분함량은 각각 43.0 및 14.8%로 분석되었다. Bio-drying 공정에서의 water balance 수립을 통해 송풍방향 전환시점에서의 평균 수분함량이 19.8%로 추정된 반면, 폐기물 상층의 수분함량은 39.0%로 분석되었다. 송풍방향의 전환 이후 실험종료 시점에서의 폐기물 상/중/하층의 수분함량은 각각 23.1, 13.3 및 16.0%로 분석되어, 송풍방향의 전환을 통해 폐기물 상층 수분함량의 효과적인 감소와 수분함량의 균질 분포가 유도될 수 있음을 확인하였다. 또한, 송풍량 자동제어 방식의 적용을 통해 배출가스 온도의 상승 및 하강 시점에서의 송풍량 증가 및 감소에 의해 배출가스의 온도가 특정 범위 내에 존재할 수 있었음을 확인하였으며, 송풍량의 변화가 수분 제거속도를 상승시키는 요인으로 작용한 것으로 분석되었다.
