The promotive effect of rooting with a newly developed synthetic auxin, 5, 6-dichloro-indole acetic acid (5, 6-Cl_(2)-IAA), was investigated with softwood cuttings of Euonymus japonicus Thunb, and Taxus cuspdata Sieb. et Zucc. Dipping the basal end of cuttings in 5, 6-Cl_2-IAA solutions of different concentrations enhanced the rooting of Euonymus japonicus cuttings in sand medium under mist propagation bench. Treatment of 100 ppm 56-Cl_2-IAA was more effective than IBA treatment at the same concentration. In Tuxus cuspidata,, significant rooting promotion was obtained with 10- 100 ppm basal dippings in solutions of both 5, 6-Cl_(2)-IAA and IBA. However, the root elongation appeared to be promoted by low concentrations of 5,6-CL-IAA as compared to that of IBA treated cuttings.

葡萄 Campbell Early 의 無核果 生成 및 成熟促進을 위하여 GA₃ 濃度別 그리고 몇 가지 覆袋處理를 한 實驗結果는 다음과 같다. 1. 果房重과 果粒數는 滿開 8日前 處理가 適期로서 果房重은 無處理에 비해 76.4%, 果粒數는 80.6%였다. 2. 1果房當 無核粒率(92%)과 100粒中 種子數(12個)는 滿開 18日前, Gibberellin 處理+cellophane紙 覆袋區가 가장 良好하였다. 3. 果粒數와 種子數(r=0.826) 또한 種子數와 果重間에는 정의 相關關係(r=0.841)를 나타내었다. 4. 糖度는 無處理區보다 cellophane紙 覆袋區가 9.34% 로서 높았다. 含水量과 灰分은 無處理와 新聞紙 覆袋區가 높았고 cellophane 紙 覆袋區가 낮았다. 5. vitamin C 含量은 Gibberellin 處理時期가 빠르고 無核率이 높을수록 낮은 傾向이엇다. 處理間에 있어서는 無處理와 parchment紙 袋覆區 많았고 cellopnane紙 袋覆區가 含量이 적었다. 6. Gibberellin 處理時期를 앞당기고 cellophan紙 袋覆를 하면 無核率이 높은 反面 果粒數 果重이 減少되고, Gibberellin 處理時期를 늦추고 新聞紙 覆袋를 하면 果粒數 果重은 增加하지만 無核率이 낮아졌다. The results obtained by the Gibberellin and bagging treatment on the Campbellearly grape are as follows: 1. The suitable period of treatment for cluster weight and number of berry are to be before 8 days of full bloom. The cluster weight was 76.4% and number of berries were 80.6% compared with control. 2. The ratio seedless berries of 92% per cluster, and number of 12 seedss in 100 beries were showed the best on before 18 full bloom at the bagging plots of Gibberellin treatment+cellophane paper. 3. Number of berry and number of seed (r=0.826) also were showed mutual relation of plus between the number of seed and fruit weight. 4. Soluble solid was showed higher of 9.3% at the cellophane paper bagging plot and 9.34% at the parchment paper bagging plot than the control. Juice content and ash were showed high at the conthol and newspaper bagging plot, and low at the cellophane paper bagging plot. 5. The content of vitamin C was showed low tendency at the higher of the seedless ratio with the quick Gibberellin treatment period. At the betweentreatment, the control and parchment paper bagging plot were showed much, and showed less content at cellophane paper bagging plot. 6. In advance the period of Gibberellin treatment and had cellophane paper bagging then the ratio of seedless would be high, but on the contrary, the number of berry and fruit weight decreased, and had delay the period of Gibberellin treatment and had the newspaper bagging, the number of berry and fruit weight would be increased but the ratio of seedless was low.

위암발증의 원인을 밝히기 위하여 설문조사를 통하여 강원도 화천군에 거주하는 주민들의 일반사항, 생활습관 및 영양섭취실태와, ELISA법으로 Helicobacter pylori 감염률을 조사하였다. 조사 대상자는 40∼69세까지의 지역주민 169명으로 남자 79명, 여자 90명이었으며 그 결과는 다음과 같다. 조사 대상자의 학력은 65.7%가 초등학교 이하였으며, 월수입은 60%가 50만원 이하였다. 대상자의 62.7%가 농업에 종사하였고 자녀수는 64.3%가 3∼5명이었으며 대상자의 34.5%가 흡연을 하고 있었고 68.4%가 음주를 한다고 대답하였다. 대상자의 전체 평균신장은 156.7㎝로 여자는 150.1㎝, 남자는 164.4㎝ 이었다. 평균체중은 61.1㎏으로 여자의 체중은 57㎏, 남자는 65.7㎏이었으며 BMI는 전체 평균 25.5%로 여자는 24.8%, 남자는 20.1%이었다. Helicobacter pylori의 감염률은 전체 조사대상자의 66.3%이었으며, 여자의 67.7%, 남자의 64.6%가 감염되었고 연령별로는 40대의 70%, 50대의 62.2%, 60대의 69.4%가 각각 감염된 것으로 나타났다. 일상 생활 요인에 따른 Helicobacter pylori의 감염률은 흡연의 정도가 심하고 학력이 낮으며 월수입이 낮을수록 높은 경향을 보였다. Helicobacter pylori의 감염여부에 따라 감염자와 비감염자의 영양섭취량을 조사해 본 결과 비감염자는 감염자와 비교해서 에너지, 총단백질, 동물성 단백질, 칼슘, 비타민 C 섭취량이 높은 경향을 보였으며 철분과 niacin의 섭취량은 낮은 경향을 보였다. To examine the relationship between the casual infection of gastric cancer and lifestyle and nutritional status, we surveyed 169 persons, 90 females and 79 males, aged 40∼69 years from June 7 to June 14, 1997, in Whachon area, Kang-Won Do, Korea. For this purpose, we investigated Helicobacter pylori infection and identified the effect of sex, age, smoking, alcohol consumption, economic status, occupation, life-style and food intake on Helicobacter pylori infection. Helicobacter pylori status was evaluated using an enzyme-linked immunosorbant assay(ELISA) for anti-Helicobacter pylori immunoglobulin G(IgG). Helicobacter pylori infection was present in 66.3% of total subjects, namely, 67.7% of female and 64.6% of male and its prevalence increased with smoking, low education level and low monthly income. Energy, total protein, calcium and vitamin C intakes in the negative Helicobacter pylori infection group were higher than those in positive Helicobacter pylori infection group. However iron and niacin intakes were lower in the Helicobacter pylori negative group than in the positive group.

Malignant fibrous histiocytoma is the most common soft tissue sarcoma in adult life and shows a mixed proliferation of both fibroblastic and histiocytic cells. Because of its highly variable morphologic pattern, this tumor has often been confused with other sarcomas such as pleomorphic rhabdomyosarcoma and liposarcoma. We report a case of malignant fibrous histiocytoma occurring in a 22-year-old male who presented with a adult's fist-sized mass with several brown colored nodules on the right buttock of 3 years' duration. Histologic findings shows spindle cells arranged in a storiform pattern characteristic of the typical pleomorphic malignant fibrous histiocytoma.

人蔘種子의 發芽生理 : 開匣後 低溫處理에 따른 生理活性化物質의 同定과 變化 Indentification and Changes of Physiologically Active Substances During Low Temperature Storage of Dehisced Seeds

權宇生,李政明 경희대학교 부설 식량자원개발연구소 1991 硏究論文集 Vol.12 No.-

Experiments were conducted to isolate and identify substances responsible for dormancy and seed germination of dehisced seeds of ginseng (Panax ginseng C. A. Meyer). Radish cotyledon expansion bioassay revealed that the seed extract did contain a considerable amount of cytokinin-like substances and these substances were apparently decreased during the low temperature storage. GA-like activities were also found in the extract and these activities increased during the low temperature storage of dehisced seeds. TLC analysis of the purified extract exhibited several bands with none of them identical to the tested cytokinins; zeatin, zeatin riboside, kinetin and benzyladenine. The band, corresponding to Rf 0.36 in the TLC plate, showed definite cytokinin activities even after the several steps of purification.

권우성,김준수,채진욱,이근미,정승필,문용 영남대학교 의과대학 2003 Yeungnam University Journal of Medicine Vol.20 No.1

정상체중을 가진 성인 남성에서 지방과다(adiposity)와 심혈관계 질환의 위험요인과의 관련성을 알아보고자 하였다. 2001년 1월 3일부터 12월 31일까지 영남대 학교의료원에서 종합검진을 받은 만 28∼69세 성인 남성 129명을 대상으로 연령, 신체계측, 혈압, 공복 혈당, 혈청 지질대사치와 체성분 검사를 실시하였다. 체질량지수(BMI)가 18.5∼23 kg/㎡(76명)인 정상체중군과 23∼25 kg/㎡(53명)인 과체중군으로 분류하고, 체비방률, 체지방량과 위험인자들(수축기혈압, 이완기혈압, 공복시 혈당, 중성지방, 저밀도지단백, 고밀도지단백)의 상관관계를 분석하고, 정상체중군을 지방과다에 따라 3군으로 나누고, 각 군과 과체중군에서 심혈과 질환의 위험인자를 평가하였다. 정상체중의 제1군을 기준으로 제2, 3군과 과체중군의 위험인자 존재에 대한 비차비(odds ratio)를 조사하였다. 정상체중군에서 지방과다 변수들(adiposity variables: 체지방량, 체지방률)과 수축기 및 이완기 혈압, 저밀도지단백, 중성지방에서 유의한 상관관계가 있었다. (P<0.01). 나이를 보정하고 난 뒤 제1군을 기준으로 제3군(체지방율: 3.7, 체지방양: 4.7)과 과체중군(체지방율: 6.6, 체지방양 11.5)에서 위험인자에 대해 더 높은 비차비를 가졌다. 지방이 많은 정상체중의 성인남성은 적은 지방을 가진 성인 남성보다 심혈관 질환에서 더 높은 유병 위험도를 가졌다. 지방 측정은 정상체중군에서 심혈관계 질환의 위험인자외에 추가적인 정보를 제공할 수 있었다. Background: Most of all studies about the relation between the health risk and obesity are based on the European and American data. The purpose of this study is to examine the relation between adiposity and factors for cardio vacular disease (CVD) in normal weight individuals. Materials and Methods: Normal weight subjects with a body mass index (BMI) between 18.5 and 23 kg/㎡(76 subjects) and overweight subjects with a BMI between 23 and 25 kg/㎡ (53 subjects) were retained for this study. Normal weight subjects were divided into three group of each adiposity variable, then three group and the overweight group were evaluated for the presence of CVD risk factors and analyze the correlation coefficients between adiposity variables and risk factors controlled for age in normal weight, overweight groups. Using logistic regression analysis, the odds ratio (OR) for the prevalence of risk factors for each group of adiposity variables and the overweight group was estimated relative to the first group in normal weight subjects. Results: Systolic BP, diastolic BP, LDL cholestrol, HDL cholesterol, triglycerides in normal weight subjects were significantly correlated with all adiposity variables (P<0.01). Third group (3.7 for %fat and 4.7 for fat mass) of adiposity variables in the normal weight group and the overweight group (6.6 for %fat and 11.5 for fat mass) tended to have higher ORs compared to first group for risk factor variables. Conclusion: Normal weight subjects with elevated adiposity had higher prevalence of risk factors than normal weights subjects with less adiposity. Measuring of adiposity added additional information of cardiovascular disease risk factors in normal weight subjects.
