        Inhibition of oxidative stress induced-cytotoxicity by coptisine in V79-4 Chinese hamster lung fibroblasts through the induction of Nrf-2 mediated HO-1 expression

        Hyeon‑Gyun Jo,Cheol Park,Hyesook Lee,Gi‑Young Kim,Young‑Sam Keum,Jin Won Hyun,Taeg Kyu Kwon,Yung Hyun Choi,Su Hyun Hong 한국유전학회 2021 Genes & Genomics Vol.43 No.1

        Background Coptisine is a natural alkaloid compound and is known to have multiple beneficial effects including antioxidant activity. However, whether it can protect lung fibroblasts from oxidative damage has not been studied yet. Objectives To investigate the potential inhibitory effect of coptisine against oxidative stress in V79-4 lung fibroblast cells. Methods V79-4 cells were treated with H2O2 (1 mM) in the presence or absence of coptisine (50 µg/ml), N-acetyl cysteine (NAC, 10 mM) or zinc protoporphyrin IX (ZnPP, 10 µM) for the indicated times. The alleviating effects of coptisine on cytotoxicity, cell cycle arrest, apoptosis, reactive oxygen species (ROS) production, DNA damage, mitochondrial dynamics, and inhibition of ATP production against H2O2 were investigated. Western blot analysis was used to analyze the expression levels of specific proteins. Results Coptisine inhibited H2O2-induced cytotoxicity and DNA damage by blocking abnormal ROS generation. H2O2 treatment caused cell cycle arrest at the G2/M phase accompanied by increased expression of cyclin-dependent kinase (Cdk) inhibitor p21WAF1/CIP1 and decreased expression of cyclin B1 and cyclin A. However, these effects were attenuated in the presence of coptisine or NAC. Coptisine also prevented apoptosis by decreasing the rate of Bax/Bcl-2 expression in H2O2-stimulated cells and suppressing the loss of mitochondrial membrane potential and the cytosolic release of cytochrome c. In addition, the activation of nuclear factor-erythroid-2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) was markedly promoted by coptisine in the presence of H2O2. However, zinc protoporphyrin IX, a potent inhibitor of HO-1, attenuated the ROS scavenging and anti-apoptotic effects of coptisine. Conclusions Based on current data, we suggest that coptisine can be used as a potential treatment for oxidative stress-related lung disease.

        1789년(정조 13) 永祐園에서 顯隆園으로의 遷園 절차와 의미

        이현진(Lee, Hyeon-jin) 서울시립대학교 서울학연구소 2013 서울학연구 Vol.- No.51

        In 1789, King Jeongjo moved Yeong’wu-weon(永祐園), the mausoleum of his father, who was the late Crown Prince Jang’heon(“Jang’heon Seja, 莊獻世子”), from its original location which was the Baebong-san(拜峯山) Mountain of the Gyeong’gi-do province’s Yangju(楊州) area, to a new location which was the Hwa-san(花山) Mountain of Su’weon. The new mausoleum for his father was entitled “Hyeon’ryung-weon(顯隆園).” And there were two reasons for the moving: Yeong’wu-weon was damaged and had to be repaired, and a new location for the late Crown Prince was arranged out of a hope for King Jeongjo to have a child. General process for the moving of a mausoleum was established for the first time inside 『Supplemental Version to the Dynasty’s Five Rituals(“Gukjo Sok-O-Rye’eui, 國朝續五禮儀”)』, which was published in 1744. From the opening of an old mausoleum(“Gye’weon, 啓園”) to the insertion of the coffin(“Jae’gung, 梓宮”) into the new mausoleum, all steps were observed, and with the Wu’je(虞祭) memorial service, the process was completed. Jeongjo tried to find a couple of meanings from his effort to move his father’s mausoleum. It was a huge triumph for him, as he wanted to build a platform for reinstating his father’s honor for a very long time, and also reinforce the ruling authority of himself.

        본 연구는 휴대용 핵종분석기를 이용하여 부산지역의 지역별 환경방사선을 측정하여 휴개용 핵종분석기의 유용성을 평가하고자 한다. 측정 대상은 부산의 중심에 위치한 부산진구 소재 송상현 광장을 중심으로 9곳의 환경 방사선을 측정하였다. 측정결과 부산역과 부산대학교를 제외한 대부분의 지역에서 환경방사선은 비슷한 결과를 나탄내었다. 검출된 핵종은241Am, 133Ba, 54Mn등이 검출되었고 핵종분석기에 내장된 핵종정보가 부족하여 알 수 없는 핵종들도 검출되었다. 실험에 사용한 휴대용 핵종분석기는 분해능이 8% 정도로 자연방사성 핵종과 인공방사성 핵종을 핵종별로 정확하게 분석하기 위해서는 제조사의 개선이 필요한 것으로 판단된다. This research aims at measuring the environmental radioactivity at each area of Busan using a potable radio-isotope identification system, and assessing the utility of the potable radio-iosotope identification system. As for the target for measurement, the environmental radioactivities of nine areas centered around Songsanghyeon Square in Jin-gu located in the center of Busan were measured. As the measurement result, the environmental radioactivities were similar in most of the areas except in Busan station and Busan University. The nuclides, such as 241Am, 133Ba, 54Mn and so on, were detected, and some nuclides whose identity was unknown because of lack of information built in the radiation spectrum analyzer were also found. The potable radio-isotope identification system used in the experiment had about 8% of resolving power, so for more precise analysis into the nuclides of natural background radiation and artificial radiation in each type, the manufacturer needs to improve the analyzer.

        Background: Intratumoral injection of OK-432 produced significant antitumor effects. There are reports that OK-432 was injected directly into tumor tissue on gastrointestinal tracts and HCC tissue, producing decrease in serum alpha-fetoprotein level. We adopted this technique for treating locally advanced lung cancer. The object of this study is to evaluate the local therapeutic efficacy, side effects of injection for treating symptomatic mass. Methods: Twenty lung cancer patients (13 males and 7 females) underwent sonography guided OK-432 injection. We analyzed relationships between response of OK-432 and response of skin test, histology and age. Pain that patients feel was evaluated by VAS (Visual Analog scale). Results: A significant decrease of tumor size was observed. The mean pre-injection diameter of the lesions was 54.7±11.3mm, PR rate were 15.0% (3/20) and minimal change (50%<tumor size decreased.) patients were 35.0% (7/20). The VAS score before injecting OK-432 into the lesion was 5±3, this was decreased to 2.5±1.5 (p=0.04). Object response was significantly correlated with skin response, adenocarcinoma, and age. Conclusion: A significant decrease of tumor size and pain was observed. So OK-432 is a valuable treatment option for patients with symptomatic lesion from advanced lung cancer who are not amenable to further therapy.

        Long-term alcohol consumption have significant harmful effects as fatty liver, hepatitis, and cirrhosis on the hepatic tissues. After voluntary administration of 8% alcohol(18.67㎖/kg/day) for 120 days, the hepatic tissues of ICR mice were daministered with Kunryeongtang extract(KRE;1.24g/kg/day) were observed to investigate the repaire effects of KRE for hepatic damages that caused by chronic alcohol administration. In chronic alcohol administered group, the vacuolation such as fat accumulation(steatosis) were increased in cytoplasm, the destructive configuration of liver plates were shown in necrotic lesion. These regions are aggregation of inflammatory component cell as lymphocytes, neutrophil leucocytes and Kuffer's cell. These hepatic damages were aggravated with time course. In KRE treated group, the decreased of vacuolation and normal construction of liver plates were appeared. These results indicated that the KRE work on the repair of hepatic damages induced chronic alcohol administration.

        Objective: This study was designed to evaluate the effect of premedication of ramosetron orally disintegrating tablet (ODT), a potent 5-HT3 receptor antagonist, for prophylaxis and treatment of postoperative nausea and vomiting (PONY) undergoing breast cancer surgery using patient controlled analgesia (PCA). Material and Method: 130 women classified ASA physical status Ⅰ-Ⅱ, aged 24-60 yr, undergoing elective breast cancer surgery, were randomized. A standard general anesthetic technique and postoperative PCA using fentanyl and ketorolac were used. Patients were assigned to one of three groups; group A (no prophylactic antiemetics were administered), group B (4 mg of ondansetron ODT was administered 30 minutes before induction), and group C (0.1 mg of ramosetron ODT was administered 30 minutes before induction). Episodes of nausea and vomiting, the use of rescue antiemetics, degree of pain, adverse events, and level of satisfaction were checked during 24 hr after the operation. Results: The overall incidence of PONY during the 24 hours after the operation in group B and C were decreased. The incidence of nausea after 6 hours after the operation and the frequency of the use of rescue antiemetics were significantly lower compared with group A and B. The patients in group C were more satisfied with control of PONY than others. Conclusion: This study results suggest ramosetron ODT was an effective way to prevent PONY in breast cancer surgical patients using PCA.
