In order to evaluate the mutagenic effects of extractable indoor air pollutants (organic matters), we measured the mutagenic activities by sensitive microsuspension Ames test using new tester strains (YG 1024 and YG 1029). And additionally to evaluate the mutagenic effects on vital cell, we examined the frequencies of micronucleus appearing in lymphocytes from dye handling workers and controls. This study was conducted from Jan. to May, 1995. The extractable indoor air pollutants were collected by low volume air sampler in a general office room and 3 of dye handling factories. And the environment of general office room divided into 3 different groups according to the type of room heaters. To determine the frequencies of micronucleus appearing in lymphocytes, we sampled peripheral venous blood from 20 of dye handling workers and 20 of controls, and cultured, and then examined the lymphocytes. The results obtained were as follows: 1. The indirect mutagenic activities of extractable organic matters from suspended particulates collected in a general office room were higher than the direct one. 2. The strain YG 1024 was the most sensitive, and the increasing order of test strains that showed higher number of revertant were YG 1024, YG 1029, TA 100, TA 98. 3. In the general office room, the room using kerosene heater showed the highest mutagenecity, and the next was buthan gas heater, and non-heating room in order. 4. The mutagenic effects of suspended particulates in dye handling factories on the strain YG 1024 was 1.2 times higher than YG 1029. 5. The frequencies of micronucleus appearing in lymphocyte of the circulating blood of dye handling workers and the control were 5.65±2.97‰ and 4.65±0.97‰, respectively. And the difference was statistically significant.

Effect of Dietary Monascus Pigment on the Liver Damage Induced with CCI₄in Rats

윤종국,--,--,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2003 Journal of biomedical laboratory sciences Vol.9 No.3

In the biological world, there are a number of ecological fights for survival between each organism such as plants, animals and microorganism. In such events, an organism can use its natural bioactive products as defence agent against other organism. Furthermore, natural bioactive products can be utilized for medicine or functional food. Recently, we investigate the effect of Monascus pigment extracted from a fungus, Monascus anke, on the alcohol metabolism and blood lipid profile. In the present study, it is observed that Monascus pigment supplemented dietary may have a hepatoprotective effect on rat's liver damage induced with CCl₄. By treatment with CCl₄(3 times, I.P), liver damage was reduced more in the rats fed 2% Monascus pigment extract supplemented diet than those fed standard diet, based on the serum levels of alanine aminotransferase, microsomal glucose-6-phosphatse activity and hepaic malondialdehyde content. On the other hand, oxygen free radical generating enzymes, hepatic P-450 dependent aniline hydroxylase, xanthine oxidase, and oxygen free radical scavenging enzymes, hepatic glutathione S-transferase, catalase, superoxide dismutase activities were generally higher both in CCl₄, treated group and control fed 2% Monascus pigment extract supplemented diet than those fed standard diet. In conclusion, the rats fed 2% Monascus pigment extract supplemented diet showed more reduced liver damage than those fed standard diet, which may be due to the acceleration of oxygen free radical metabolism.

A 35-year-old man was referred to the department of Oral and maxillofacial surgery of Chonnam university hospital for the chief complaint of asymptomatic swelling on the buccal vestibule of upper right canine area. Radiographs revealed that the upper right canine was impacted and there was a well-circumscribed pericoronal radiolucency related with the canine. Multiple radiopaque foci were scattered in the radiolucent lesion, and the roots of the lateral incisor and the first premolar related to the lesion showed external resorption. The radiographic features of this lesion were typical of adenomatoid odontogenic tumor, but considering the gender and age of the patient, the tentative diagnosis was made as calcifying odontogenic cyst. Microscopically this lesion was diagnosed as calcifying odontogenic cyst, Because calcifying odontogenic cyst has no pathognomonic feature of radiographs, to consider radiographic features with clinical findings is necessary in order to establish more correct diagnosis.(Korean J Oral Maxillofac Radiol 2000; 30: 223-227)

The expression frequency of BrdU-induced fragile sites was examined in stomach cancer patients to determine whether this parameter could be used as a marker of genetic susceptibility in at-risk individuals. G banding performed to detect fragile sites. No difference was found in expression frequency between the stomach cancer patients and a group of normal individuals(p=0.7). This indicates that the expression frequency of BrdU-induced fragile sites is not a suitable marker for assessing genetic susceptibility in stomach cancer patient.

합성섬유의 유연제 사용에 따른 유연성·대전성에 대한 고찰

南潤子,朴榮姬 慶熙大學校 1995 論文集 Vol.24 No.-

In this study, I examined the variation of the three main synthetic fabrics ― polyester, nylon, and acrylic fabric ― in respect of softness and antistatic property according to increasing fiber softening agent treatment frequency. The aim of this study is to add more efficient and economic benefits in the clothing life. The results acquired from this study were as follow. 1. Softness variation according to increasing softener treatment frequency. There wasn't any significant change with plain structure polyester and acrylic fabric in spite of increasing softener treatment frequency. According to increasing softener treatment frequency in tricot knit polyester, no change was found in warp direction but softness of weft direction was improved. 2. Antistatic property variation according to increasing softener treatment frequency. When softener treatment frequency was increased, there was a little difference in decreasing degree of antistatic amount according to the kind of fabric and friction cloth in all samples, but antistatic property was improved in all samples.

백영석,안동현,조연규,남정현,최보율,강윤주,고복자 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.3

연구목적 : 청소년을 대상으로 장애가 있는 식이태도 및 식이행동과 관련된 요인들에서 인종과 문화적 차이가 있는가를 보는 것이다. 방 법 : 1996년도에 3129명의 중고등학교 남녀 학생을 대상으로 학교 장면에서 신체 계측과 설문지를 통하여 수집하였으며 연령은 13세부터 16세 사이의 학생들로 분포되었다. 학생들의 분포는 서울 지역의 663명, 양평 지역의 821명, 조선족이 사는 연길 지역의 830명 그리고 한족이 사는 길림 지역의 815명이었으며, 그들은 모두 키, 몸무게, 신체질량지수, 부모의 수입, 아버지의 학력, 체중조절 설문지, 신체상 척도 및 식이태도검사 등의 내용을 완성하였다. 결 과 : 신체질량지수(BMI)에서는 지역, 성별, 사회경제적 상태에 따른 차이가 없었다. 연길과 길림 지역의 학생들이 서울과 양평 지역의 학생들보다 심한 저체중과 심한 과체중을 갖는 학생들이 많았다. 연길과 길림 지역의 학생들이 서울과 양평의 학생들보다 식이태도검사(EAT-26)의 평균치가 높아 식이태도와 식이행동이 나빴다. EAT-26의 20점 이상인 식이장애의 고위험군은 연길 지역의 학생이 6.9%로 네 집단 중에서 가장 많았다. 한국의 양평지역과 서울 지역의 학생들이 신체상 척도(BIS)의 평균치가 연길 지역과 길림 지역의 학생들보다 의미있게 높았다. 즉 한국의 학생들이 중국의 학생들보다 자신의 신체에 대하여 부정적인 생각을 갖고 있었다. 체중조절 행동의 유병율은 서울 지역 학생들이 26.7%, 양평 지역 학생들이 23.2%, 연길 지역 학생들이 10.6%, 그리고 길림 지역 학생들이 4.6%이었다. 식이조절과 운동은 한국의 학생들이, 식이조절과 약물사용은 중국의 학생들이 가장 많이 하는 방법이었다. 결 론 : 본 연구를 통하여 한국과 중국에서도 식이장애가 결코 적지 않을 것이라는 사실을 확인하였고, 식이장애는 인종과 사회문화적 요인에 의해 크게 영향을 받는다는 것, 마지막으로 식이태도와 식이행동 및 그와 관련된 요인들을 통해서 네 지역간의 문화전이 상태를 확인할 수 있었다. Objectives : The goal of this research was to attempt to examine ethnic and cultural differences in factors associated with disordered eating attitudes and behaviors. Methods : Data were collected from the four groups of 3,129 high school students aged between 13 and 16 years who completed school-based survey conducted in 1996. The students (663 Korean urban, 821 Korean rural, 830 Korean-Chinese and 815 Chinese adolescents) completed an instrument which assessed weight, height, Body Mass Index(BMI), parental income, father's level of education, weight control questionnaire, Body Image Scale(BIS), and eating attitudes and behaviors using the Eating Attitude Test-26(EAT-26). Results : BMI did not vary significantly by race, sex, and socioeconomic status. There were many severely underweight and severely overweight students among Korean-Chinese and Chinese than among Korean urban and Koran rural students. The EAT-26 mean scores of Korean-Chinese and Chinese subjects were significantly higher than those of Korean urban and Korean rural subjects. The EAT-26 mean score of Korean-Chinese was the highest among the four racial groups. The prevalence of high risk EAT-26(EAT-26≥20) students of Korean-Chinese was 6.9% which was the highest among the four groups. The BIS mean scores of Korean rural and Korean urban subjects were significantly higher than those of Korean-Chinese and Chinese subjects. The Korean subjects were more dissatisfied with their body than the Chinese. The prevalences of weight control behaviors were 26.7% in Korean urban, 23.2% in Korean rural, 10.6% in Korean-Chinese, and 4.6% in Chinese subjects. Dieting and exercise were most popular for weight reducing in Korean subjects. Dieting and drug use were most popular in Chinese subjects. Conclusion : These data suggest that there must be many eating disorder patients in Korea and China, and the eating attitudes and behaviors are influenced by ethnic and cultural factors. Implications for understanding sociocultural influence on eating attitudes and behaviors and acculturation are discussed.
