The Anti-cancer Effect of Oriental Medicine Chung-Ri-Ja-Gam-Tang in the Mouse with Metastatic Lung Cancer. Proceedings of International Symposium on East-West Medicine, Seoul. 231-243, 1999.-The oriental medicine Chung-Ri-Ja-Gam-Tang is an herbal medicine which has been used for pulmonary diseases and known as having immune stimulatory effects. It has been known effective in lung cancer. So we studied the effects and the mechanisms of this herbal medicine it the mouse with metastatic lung cancer. The metastatic lung cancer of the mouse was produced with melnoma cell line(B16BL/6).5×10□/mouse tumor cells were injected intravenously to the CDF1 mouse via tail vein. The mice were divided 4 groups. The first group was treated with 50mg/kg extract of Chung-Ri-Ja-Gam-Tang per oral for 10 days after cancer cell injection, second group treated with saline after cancer cell injection, the third group with medicine without cancer cell, and the last group with saline only. After 10 days treatments some of the mice were scarificed and the lung and spleen was removed. The survival duration, weight change, the number of metastatic cancer nodule of the lung, the NK cell activity, the capacity of cytokines(INF-γ,INF-α,IL-2) production and the proliferation activities of mouse lymphocytes were measured. The surival times of the group 1 mice were longer and the weight loss was less than the group 2 significantly. The number of the metastatic nodule of the lung were decresed in the group 1 than the group 2. The production of INF-γ,was increase in group 2 than group 3 and 4, IL-2 production was increased in group 1 than group 2,3,4 significantly. There was no difference in TNF- α production and proliferation activity of lymphocyte in each group. The NK cell activity was significantly increased in group 1 than group 2,3,4. We conclude that the Chung-Ri-Ja-Gam-Tang has the effect of increasing the NK cell activity of the CDF1 mouse with metastatic lung cancer(B16BL/6). And it is suggested that the increased production of the IL-2 is the mechanisms of enhanced NK cell activity.

Kyung‑Yoon Jeon,Eun‑Ji Ko,Young Lim Oh,Hongbae Kim,Wan Kyu Eo,김아리,Han Gyu Sun,Meesun Ock,Ki Hyung Kim,Hee‑Jae Cha 한국유전학회 2020 Genes & Genomics Vol.42 No.10

Background Human endogenous retroviruses (HERVs) constitute around 8% of the human genome and have important roles in human health and disease, including cancers. Previous studies showed that HERV envelope (Env) proteins are highly expressed in cancer tissues and co-related with cancer progression. KAP1 has been reported to play a key role in regulating retrotransposons, including HERV-K, through epigenetic silencing. Objective The relationship between KAP-1 and HERV Envs expressions was analyzed only in tumor cell lines and has not yet been studied in cancer tissues. In this study, we analyzed the expression patterns and relationship between KAP1 and HERV Env proteins in ovarian cancer tissues. Method The expression patterns of KAP-1 and HERV Env proteins, including HERV-K and HERV-R, were analyzed in ovarian cancer tissue microarrays that contained 80 surgical specimens, including normal ovary and malignant ovarian cancers. Results The expression of HERV-R Env and KAP1 proteins is signifcantly higher in ovarian cancer compared with normal ovary tissues. However, the expression of HERV-K Env did not change signifcantly in cancer tissues. The expression patterns of HERV-K Env and HERV-R Env signifcantly increased in early stages of cancer and KAP1 expression was higher in certain stage and types of cancers. However, the expression of HERV-K Env, HERV-R Env, and KAP1 did not change in diferent age groups. The correlation between the expression of KAP1 and HERV-Env, including HERV-K and HERV-R, was not signifcantly correlated. Conclusions The results of this study showed that there was no signifcant correlation between the expression of KAP1 and HERV Env proteins in ovarian cancer tissues, unlike studies with cell lines in vitro. These results suggest that the actual expression of HERV Env proteins in ovarian cancer tissues may be regulated through various complex factors as well as KAP1.

『딕테』에 나타난 디아스포라의 언어 고찰

윤향기(Yoon hyang-ki),이경영(Lee Kyung-young) 한국비평문학회 2008 批評文學 Vol.- No.29

This paper is an analysis about Dictee written by Cha, Hak-Kyung, a Korean-American, who tried for works beyond genre focusing on matters of diaspora and language. Until he passed away at age of 31, he was a writer who solidly dealt with images, text relations, implication of women and bodies, and substance of diaspora by moving about most energetically in many sorts of medias such as books, films, videos, mail arcs, ad criticism, stamp arts, and performing arts. Dictee has some difference from existing books that we've seen so far. This book tells stories about shunned strangers, existence of minor races, experience of women, suffering as Japanese colony, longing of innocent love, and vivid self-awareness of himself, within a dispersed world that he starred from himself. She already expressed a multicultural ideal in which all the diversity can harmonize beyond the walls of races, religions, languages, and ideology. The root of multiculturalism is based on pluralism. In this paper, the author deeply scrutinized the non-existence and transcendence of time and space and their eternity. And he also accepted Cha Hak Kyung's mythological recognition as historical consciousness replaced by lives with wings and free flight. Kim, Kyum-Hyang expressed Dictee as voice of shaman or voice of The Princess Bari in Comparison Study of Mythologies Appeared in Dictee Written by Cha, Hak-Kyung and Comfort Woman Written by Nora Okja Keller. However, this paper places more weight on the image of 'Butterfly' of Chuang-tzu, that is, restoration or transcendence. In other words, it is seen that women independently in their own language of Diaspora speaks about women's identity, which is even further expanding to the voice that Koreans make toward the world. In particular, Dictee is an example that resurrects Diaspora's linguistic outsiders' view into even strong points. This paper analyses and talks about the identity of Diaspora on the work beyond genre or mixed one. Especially, this unusual success is due to author's excellence in artistic talent and study of diverse cultural theories. However, more originally speaking, this is just because the author was able to experience by himself his disruption and dismantlement through his unique antecedent and thus reform this into artistic works.

The incidence of aseptic meningitis infection is ensuing and threatening the health of children. Enteroviruses are the major agents of aseptic meningitis and identification of virus has been a clue to diagnosis and epidemiology. The outbreak of aseptic meningitis occurred in Pusan, 1998. Patients were concentrated from April through November. Children were more susceptible than adults. Among 306 cases of specimens from stool, throat swab tested, only 7.2% were positive on virus isolation, 12 cases from stool and 10 from throat, respectively. All isolated 7 serotypes of viruses represented cytopathic effect on cultured cells. Three types of echovirus 6, 25, 30 and coxsackievirus B2, B3, B4, B6 were identified by neutralizing anti body test. Isolated coxsackievirus and echovirus were observed by an electron microscope with negative staining.

In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

尹惠京,盧榮洙 慶熙大學校 1985 論文集 Vol.14 No.-

"Studies on the accumulation phenomenon of metal elements in rats, and the examination of the contents of metal elements in magnetite." An examination was made on the contents and kinds of metals in magnetite and on the amount of heavy metals in the internal organs when administered to a rat. It was found to contain about 32.8% iron, about 1% copper, and very small amounts of lead, and cadmium respectively. After magnitite was administered to a rat, using a control group for comparison, the contents of heavy metal in the organs was apt to increase. Test results showed the following effects: 1) Iron increased rapidly in the liver after a week but after two to three weeks, didn't show any tendency to increase. Iron increased slowly in the kidneys. 2) Copper increased in the liver and the kidneys, but it didn't increase in the lungs. 3) Lead also increased in the organs slowly. 4) Cadmium was detected in the organs, but tests did not confirm a rapid accumulation.

대량생산을 위한 김치의 산업화에 있어서 가장 큰 문제점인 유통시의 산패현장과 포장팽대 및 파손을 지연시켜 김치의 저장기간을 연장하고자 이산화탄소 흡수능력을 가진 물질을 가스흡수제로 처리하여 저장중 김치의 품질을 검토하였다. 품질평가를 위한 측정항목은 pH, 산도, 색상, 이산화탄소 함량 및 젖산균수 그리고 총균수를 측정하였다. 수산화칼륨, 수산화칼슘, 수산화나트륨과 같은 알칼리물질과 연화마그네슘, 염화칼슘과 같은 염화합물을 가스흡수제로 사용한 결과, 수산화칼륨과 수산화나트륨처리구가 타처리구에 비해 pH의 감소가 적었으며, 또한 산도의 증가가 다소 낮았다. 수산화칼륨과 수산화나트륨을 각각 0.25%, 0.5%, 0.75% 세단계의 농도로 처리한 결과 pH와 산도에 있어서 수산화칼륨처리구가 수산화나트륨처리구에 비해 높은 pH와 낮은 산도를 나타내었다. 또한 각 처리구의 농도에 따라 큰 차이가 나타나지 않아 간편성과 경제적인 면, 그리고 시각적인 면을 고려해 볼 때 0.25% 수산화칼륨처리구가 탄산가스흡수에 의해 김치의 저장기간을 연장하는데 다소 효과를 보였다. PE bag으로 포장된 수산화칼슘과 PE flim(0.02㎜)으로 포장한 0.25% 수산화칼륨을 가스흡수제로 사용하여 무처리구와 비교하여 저장중 김치의 품질을 검토하였다. 저장중 0.25% 수산화칼륨처리구와 시판용 김치의 가스흡수제인 수산화칼슘처리구를 비교할 때, 수산화칼륨처리구가 무처리구에 비해 pH 및 산도의 차이가 컸으며, 김치의 조직과 국물속에 용해되어 있는 이산화탄소의 함량도 적었다. 그리고 총균수에 있어서 타처리구에 비해 수산화칼륨처리구가 높은 값을 나타내었다. When kimchi was manufactured and circulated, largest question is rancidity phenomenon and packing swelling. This study was conducted to prevent these phenomenon and prolong the shelf-life of kimchi. KOH, NaOH, Ca(OH)_2, MgCl_(2), and CaCl_(2) were used to gas-absorbent. The pH of kimchi used KOH, NaOH was higher than the others. The acidity of kimchi used KOH, NaOH was lower than the others. The concentration of KOH, NaOH was 0.25%, 0.50%, 0.75%. The decrease of pH and increase of acidity that kimchi dealt with KOH were lower than kimchi used NaOH. There in no significant difference in concentration of gas-absorbent. Comparision of kimchi used 0.25% KOH and Ca(OH)_2. Ca(OH)_2 packaged PE bag and 0.25% KOH packaged PE film(0.02㎜) were used to gas-absorbent. On comparision to control, kimchi dealt with 0.25% KOH was higher than kimchi used Ca(OH)_2 at pH and acidity. The CO_(2) contents of kimchi dealt with 0.25% KOH was lowest. The number of total microbe kimchi dealt with 0.25% KOH was highest.
