잎파래 (Enteromorpha linza)의 葉體無菌化와 元形質體 培養

裵光星,宋相鎬,鄭圭和 慶尙大學校 1991 論文集 Vol.30 No.2

잎파래(Enteromorpha linza) 葉體의 無菌化와 葉體에서 分離한 原形質體의 培養에 關한 몇가지 條件을 決定코자 하였다. 洗劑로 葉體의 附着微生物을 除去하기 爲해서는 0.1%液으로 15∼20分間 洗 하는 것이 效果的이었으며, 組織內部의 微生物은 1% KI-I2液으로 2.5∼5分間 處理하여 抗生劑 2%가 添加된 培地함으로서 除去가 可能하였다. 葉體의 原形質體는 2% AAP가 添加된 各種酵素液으로 容易하게 분리할 수 있었다. 原形質體의 無菌培養을 爲한 抗生物質의 添加濃度는 1.5%程道가 適當하였으며 照度는 2000lux以上일 境遇培養에 큰 影響을 미치지는 않는 傾向이었다. Basic studies for obtaining the axenic tissue, isolation and culture of protoplasts of Enteromorpha linza have been attempted. Treating with 0.1% detergent for 15-20mins were effective for cleaning the collected tissue. Exposure the tissue to a 1% KI-I2 solution for 2.5-5.0 mins subsequently culture them in the medium containing 2.0% antibiotic materials were good for inhibition of bacterial growth as well as enzyme solutions composed of abalone acetone powder, cellulase R-10, and driselase. The 2.0% antibiotic medium was good for the suppression of bacterial growth in protoplasts culture. The development of protoplasts was not largely influenced by the light strength and photoperiods.

The purpose of this inquiry is to understand the changing process of Tae-Kwon Do uniform by After thorough examination, they could be summarized as below. Tae-Kwon Do training uniforms are divided into two different types. One is a spread extended type which originally came form Japan and the other is an Korean traditional martial arts uniform. As the development of Tae-Kwon Do occurred, the uniform changed into a basic clothing form from the three countries period which included a black collar and a half black and red collar for grade holders. The differences in the length of sleeves and pants come from which material it is made of and a statement regulated by the Korea Tae-Kwon Do Federation. The uniform currently using is not the Korean traditional type which has to be worn over the head. This has a major disadvantage when putting it on and taking it off, it ruins the hair especially after sweating a lot through training. As a result, the uniform we are currently wearing has a slight problem in practicality and the historical background but the uniform itself is rogarded more as a sport uniform rather than a training uniform.

In order to investigate the relationship between blood lead with other lead exposure indices and blood pressure in occupationally lead exposed male workers, 629 workers(515 lead exposed workers and 114 non lead exposed workers) in a storage battery factory were studied. Blood lead(PbB), zinc protoporphyrin(ZPP) and urinary δ-aminolevulinic acid(ALAU) were selected as an index of lead exposure. Height and weight were also meaured with calibrated automatic height-weight machine to produce fatness index directly. Personal information on smoking and drinking history were also collected. Blood pressure was mearured by trained nurses with automatic sphingomanometer. All workers took at least 30 minute rest before their measurement of blood pressure. The results obtained were as follows: 1. The prevalence rate of hypertension of lead exposed and non-exposed workers were 3.5% in both group without any difference. 2. There were no differences of systolic and diastolic pressure between groups divided by lead exposure, smoking habit, drinking habit. but the increase of age group made the difference of diastolic pressure, and only differenct of systolic pressure observed in age group of less than 20 and that of more than 40. 3. In pearson's correlation analysis, PbB was correlated with systolic pressure significantly, but not with diastolic pressure. PbB was also correlated with pressure difference(systolic pressure-diastolic pressure). 4. There were no significant increase of systolic, diastolic pressure and pressure difference by the increase of PbB and ZPP grouping. 5. Stepwise multiple regression analysis using systolic pressure as dependent variable and PbB, ZPP, ALAU, age, work duration, smoking habit, drinking habit and fatness (weight*0.9/height-100) as independent variables, revealed that PbB, age, drinking habit and fatness in order were significantly contributed to the dependent variable. 6. Stepwise multiple regression analysis using diastolic pressure as dependent variable and PbB, ZPP, ALAU, age, work duration, smoking habit, drinking habit and fatness (weight*0.9/height-100) as independent variables, revealed that ALAU, age and fatness in order were significantly contributed to the dependent variable. 7. Stepwise multiple regression analysis using pressure difference as dependent variable and PbB, ZPP, ALAU, age, work duration, smoking habit, drinking habit and fatness(weight*0.9/height-100) as independent variables, revealed that PbB, age and fatness in order were significantly contributed to the dependent variable. 8. Logistic analysis of hypertensive conditions with categorized blood lead and other selected categorized independent variables indicated that only age(40> and 40≤) and fatness(1.0> and 1.0≤) were significantly contributed to dependent variable with 95% significant odd ratio confidence interval. With above results, lead exposure in terms of blood lead seemed to be minimally contributed to the raise of blood pressure, and the effect of blood lead was found to be more prominent on the pressure difference than the systolic and diastolic pressure themselves.

Objective : As the average lifespan of human increases, osteoporosis and osteoporosis-related fractures have become major health care problems. Despite recent advances in medical treatment, few studies have assessed the recognition of osteoporosis in general adults. This study examined the recognition of osteoporosis and analyzed the relating factors. Method : A population-based sample of 1086 adults in Asan-city, Korea was investigated with questionnaires and height, weight, Information regarding the general characteristics(gender, age, economic state), lifestylef exercise, smoking, alcohol),medical history(progestin, GH, steroid, calcitonin, PTH), demographic parameter, obesity, stress, and family history was collected through an interview using a structural questionnaire. The level of obesity was measured by the body mass index(BMI). BMD(Bone mineral density) at the lumbar spine and femoral neck was measured by dual energy X-ray absorptiometry. Osteoporosis was considered to be T-score below -2.5. Results : The prevalence of osteoporosis increased progressively with age, decreased with BMI and predominant in women by the result of x^(2) -test, T-test. Age, weight, BMI were significantly correlated with osteoporosis by the result of Pearson correlation ana1ysis(P<0.05). And age, gender, BMI, family history of osteoporosis were proved to be significant risk factors of osteoporosis by the result of multiple logistic regression(P<0.05). Conclusion : These results suggest that age, gender, BMI might be the most important risk factors of osteoporosis. And the history taking about family history of osteoporosis is helpful for diagnosing osteoporosis.

Objectives: This study was conducted with new workers who entered lead industries from 1992 to 2001 to evaluate the genetic susceptibility of ALAD (δ-aminolevulinic acid dehydratase) and VDR (vitamin D receptor) gene on health effect of lead exposure. Methods: Among the subjects of the database of lead industries at the Soonchunhyang University Institute of Industrial Medicine, only new workers were selected for this study. The total of eligible workers for this category was 3,540 workers, including non lead exposed workers of same lead industries. From stored blood in specimen bank of Soonchunhyang University, genotype of ALAD and VDR were measured using PCR method. Variables for this study were blood lead as an index of lead exposure, ZPP (zinc protoporphyrin in blood), urine ALA (δ-aminolevulinic acid), and hemoglobin as an index of hematopoietic effect of lead. Information on sex, job duration, and weight were collected for personal information. The data were analyzed using SAS (version 8.2) with descriptive analysis of t-test and multiple regression analysis. Results: Among 3,540 new employed study subjects during period of 1992-2001, 3,204 workers (90.5%) had ALAD genotype 1-1, while 336 workers (9.5%) had variant type of ALAD (1-2 or 2-2). For VDR genotype, 2,903 workers (89.7%) out of total tested 3,238 workers were belonged to type bb and 335 workers (10.5%) were type bB or BB. The distribution of genotype of ALAD and VDR were not different according to the job duration in male workers, but were different in female workers. The effect of ALAD and VDR genotype on blood lead were positively significant in the analysis of all cumulative data of new employed workers for 10 years. The effect of VDR genotype on blood lead were stronger than that of ALAD While the variant ALAD gene made decrease of mean ZPP and ALA in urine after controlling for blood lead and other covariate, the variant VDR gene made increased the mean ZPP and ALA in urine in all cumulative data analysis and cross sectional analysis by job duration. For hemoglobin, ALAD and VDR genotype did not affect the mean value. Conclusions: From the above our results, we found that ALAD and VDR genotype exerted significant effect in various way. We confirmed that the finding of a cross sectional study of protective effect of variant ALAD on the effect blood lead on blood ZPP in our retrospective study design. It was found that VDR did not exert protective effect for lead exposure as the variant ALAD did.

김화성,이성수,김용배,황보영,리갑수,안규동,장봉기,이병국 大韓産業醫學會 2001 대한직업환경의학회지 Vol.13 No.1

목 적 : 혈중 연량 및 골중 연량과 조혈기능의 생화학적 지표사이의 관련성에 f-aminolevinicacid dehydratase 효소의 유전형질의 다형질성이 어떠한 영향을 주는지를 알아보고자 연작업자 450명을 연폭로군으로 연폭로가 없는 85명을 대조군으로 선정하였다. 방 법 : 조혈기능의 생화학적 지표로는 혈중ZPP, 요중 ALA, 혈색소 및 혈구용적치를 택하였고, 이들 상호관계에 영향을 줄 수 있는 교란변수로서 성, 연령, BMI, 흡연습관, 음주습관 및 연작업자들의 경우 연폭로 기간을 조사하였다. 결 과 : 동형유전형질인 ALADI을 가진 연작업자들은 407명으로 전체의 90.4 %이었으며, 대조군에서도 77명으로 전체의 90.6 %로서 양군간에 차이가 없었다.동형 유전형질을 가진 연작업자들보다 이형 유전형질을 가진 연작업자들의 골중 연량과 혈중 ZPP의 평균값이 적었으나 통계적으로 유의하지 않았고 나머지 연구변수들의 평균도 유전형질의 구분에 따른차이는 없었다. 성, 직력, BMI, 흡연여부, 음주여부 등의 흔란변수를 통제한 후 혈중 연량 및 골중 연량과 ALAD유전형질이 혈색소에 미치는 영향을 구한 바 혈중 연량과 골중 연량만이 혈색소에 유의한 영향을 주었을뿐 ALAD 유전형질은 유의한 영향이 없었다. 반면에 혈구용적치의 경우에는 혈중 연량과 골중 연량 그리고 유전형질 모두가 유의한 영향을 주지 못했다.요중 ALA를 종속변수로 하고 관련 혼란변수를 통제한 후 혈중 연량과 ALAD 유전형질 그리고 양자의 교호작용을 독립변수로 한 회귀분석들에서 혈중 연량 및 골중 연량과 ALAD 유전형질 모두가 주효과(main effect) 및 교호작용(effect modifies-tion)이 유의하석 이형 ALAD 유전형질을 가진 연작업자들의 ALAU가 동형의 유전형질을 가진 연작업자들보다 상대적으로 낮은 값을 나타냈다.혈중 ZPP를 종속변수로 하고 관련 혼란변수를 통제한 후 혈중 연량과 ALAD 유전형질 그리고 양자의 교호작용을 독립변수로 한 회귀분석들에서 혈중연량 및 골중 연량과 ALAD 유전형질 모두가 음의주효과(maln effect)가 나타나서 이형 유전형질의 연작업자들의 혈중 ZPP가 동형 유전형질의 연작업자보다 상대적으로 적은 값을 나타냈으나 교호작용(effect modification)은 없었다. 결 론 : 상기 결과로 미루어 ALAD 유전형질은 혈색소에는 유의한 영향을 주지 못했으나 ALAU 및 혈중 ZPP에는 유의한 영향을 주어 동형의 유전형질인 연작업자보다 이형의 유전형질 연작업자들이 상대적으로 낮은 ALAU와 혈중 ZPP값을 보여주어이형유전형질이 연에 보호효과가 있다는 가설을 돼받침하였다 Objectives : To evaluate the effect of ALAD polymorphism on the relationship of blood and bone lead with hematologic biomarkers in lead exposed workers, 450 lead exposed workers and 85 non-lead exposed workers were selected. Methods : Blood lead and tibia bone lead were selected as parameters of lead exposure and blood ZPP, urinary ALA (ALAU) , hemoglobin (Hb) and hematocrit (Hct) were chosen as parameters of hematologic effect of lead exposure. Genotype of each subject was assayed and expressed as ALADI and ALAD2. Demographic information such as sex, age and personal habit of smoking and drinking were collected. Job duration of lead exposed workers was also obtained. Results : The overall prevalence of the variant allele, ALAD2 in lead exposed workers was 9.6 %(43 out of 450 lead workers) which was not differed from control workers (9.4 % : 8 out of 85) . The means of tibial lead and blond ZPP in lead workers with ALAD2 were lower than those of lead workers with ALAD1, but the differences were not statistically significant. After adjusting for possible confounders (sex, job duration, BMI, drinking and smoking status) only blood lead and bone lead contributed negatively to the level of hemoglobin with statistical significance without any contribution of ALAD genotype. On the other hand, no significant effect of blood lead, bone lead and ALAD genotype were observed on the level of hematocrit after controlling possible confounder. ALAD genotype in the multiple regression analysis of blood lead fed bone lead with log transformed urinary ALA (LogALAU) after adjusting for possible confounders showed significant main and interaction effect on LogALAU simultaneously, which resulted lower LogALAU in lead exposed workers of ALAD2 than ALAD1. It was also observed only main effect of ALAD gene type on blood ZPP after adjusting possible confounder resulting lower ZPP in lead workers of ALAD2 than ALAD1. Conclusions : With above results, it was found that ALAD polymorphism did not affect on the level of hemoglobin and hematocrit, but ALAD polymorphism made significant effect on the association of blood and bone lead with urinary ALA and blood ZPP. The lower urinary ALA and blood ZPP in ALAD2 lead workers suggested that ALAD2 genotype may be supportive for the protective effect of lead.
