I studied Song, Gyu-ryeom`s life through his `Annual Report` and writing series, `Jewoldangjip` and the ideology of the society that he lived in through the country activity. Song, Gyu-ryeom was a famous Confucian scholar who lived in Hoedeok at the latter Choseon dynasty. He was called the one of the three prominent `Songs` with Uam, Song, Si-yeol, and Dongchundang, Song, Jun-gil. The reason why Song, Gyu-ryeom`s ancestors who lived in Hoedeok was that Song, Myung-eui(Song, Gyu-ryeom`s 10th ancestor) settled there as he became the son-in-law of Hwang, Su who lived in Hoedeok. Since then many famous Confucian scholars came out of Eunjin Songs` family members and they thrived through marrying the nobles. When Song, Gyu-ryeom was a boy, he experienced Byeonjahoran and the fall of the Ming Dynasty. He also spend his adolescence under the mood that people insisted to conquer the Cheong Dynasty. So it made him follow Song, Si-yeol and Song, Jun-gil`s political and ideologic way and he learned the basic of study from them. Song, Gyu-ryeom was respected as a Confucian scholar in Hoedeok. He emphasized `Hyangeumjurye`, `Hyangsarye`, `Reading methods` at the society of the country. `Hyangeumjurye` means that Confucian scholars in the country gathered at Hyanggyo or Seowon and had a feast with prominent Confucian scholars. The Confucians learned the manner to respect honest people, to take care of the old people, and to experience good courtesy there. Also he taught students devotionally at the Sunghyeonseowon. In 1672(Sukjong 2nd year), he built the Jewoldang inside his house and spent his whole life on studying Confucianism and teaching students. Teaching students at the Jewoldang and the Sunghyeonseowon was theoretical part and Hyangeumjurye was the reformation project which included the education of practical manner. Like this, Song, Gyu-ryeomtried to carry out `manner` through personality based on Neo-Confucianism And Song, Gyu-ryeom also had the social ideology of the autonomy of the country. That idea was shown in the preface of Hoedeok Hyangyack(1672) that he wrote. Hoedeok Hyangyack was made into one book with Hoedeok Hyangyan. Then Song, Si-yeol made the preface of Hoedeok Hyangyan and Song, Jun-gil wrote it. And Song, Gyu-ryeom wrote the preface of Hyangyack which was attached to the back of Hyangyan. He was the core member to make the Hoedeok Hyangyack with two Songs. The reason why he was called as the one of the three Songs of Hoedeok might be due to this work. Hyangyack was the regulation that Hyangwon made for education and cooperation of the country people. So the Hoedeok Hyangyack also had the content like that. The Jewoldang was the place where Song, Gyu-ryeom studied and taught students with all effort at his old age. Also it was the place where he built for just studying after he abandoned his will to have a government position. The education place like this was the sign that he wanted to live with the nature and worked hard for teaching students. Song, Gyu-ryeom`s country activity showed his social ideology to improve national customs from the country customs with the spread of Hyangyack.

Bae, Gi-Sang,Kim, Dong-Goo,Jo, Il-Joo,Choi, Sun-Bok,Kim, Myoung-Jin,Shin, Joon Yeon,Kim, Dong-Uk,Song, Ho-Joon,Joo, Myungsoo,Park, Sung-Joo ELSEVIER 2019 INTERNATIONAL IMMUNOPHARMACOLOGY Vol.69 No.-

<P><B>Abstract</B></P> <P>Heme oxygenase-1 (HO-1) has an anti-inflammatory action in acute pancreatitis (AP). However, its mechanism of action and natural compounds/drugs to induce HO-1 in pancreas are not well understood. In this study, we investigated the regulatory mechanisms of HO-1 during AP using desoxo-narchinol-A (DN), the natural compound inducing HO-1 in the pancreas. Female C57/BL6 Mice were intraperitoneally injected with supramaximal concentrations of cerulein (50 μg/kg) hourly for 6 h to induce AP. DMSO or DN was administered intraperitoneally, then mice were sacrificed 6 h after the final cerulein injection. Administration of DN increased pancreatic HO-1 expression through activation of activating protein-1, mediated by mitogen-activated protein kinases. Furthermore, DN treatment reduced the pancreatic weight-to-body weight ratio as well as production of digestive enzymes and pro-inflammatory cytokines. Inhibition of HO-1 by tin protoporphyrin IX abolished the protective effects of DN on pancreatic damage. Additionally, DN treatment inhibited neutrophil infiltration into the pancreas via regulation of chemokine (C-X-C motif) ligand 2 (CXCL2) by HO-1. Our results suggest that DN is an effective inducer of HO-1 in the pancreas, and that HO-1 regulates neutrophil infiltration in AP via CXCL2 inhibition.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Desoxo-narchinol-A (DN) is a natural compound of HO-1 inducer in pancreas. </LI> <LI> Mechanism of DN-induced HO-1 is mediated by MAPK/Activator Protein-1/HO-1 signaling. </LI> <LI> DN-induced HO-1 blocks neutrophil infiltration into pancreas via inhibition of CXCL2. </LI> <LI> DN inhibits cerulein-induced acute pancreatitis (AP) and AP-associated lung injury. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Ethanol Extract of Ganoderma lucidum Augments Cellular Anti-oxidant Defense through Activation of Nrf2/HO-1

Lee, Yoo-hwan,Kim, Jung-hee,Song, Choon-ho,Jang, Kyung-jeon,kim, Cheol-hong,Kang, Ji-Sook,Choi, Yung-hyun,Yoon, Hyun-Min KOREAN PHARMACOPUNCTURE INSTITUTE 2016 Journal of pharmacopuncture Vol.19 No.1

Objectives: The mushroom Ganoderma lucidum has been widely used as a traditional herbal medicine for many years. Although several studies have focused on the anti-oxidative activity of this mushroom, the molecular mechanisms underlying its activity have not yet been clearly established. The present study investigated the cytoprotective effect of ethanol extract of Ganoderma lucidum (EGL) against oxidative stress (hydrogen peroxide, $H_2O_2$) and elucidated the underlying mechanisms in a C2C12 myoblast cell line. Methods: Oxidative stress markers were determined by using the comet assay to measure reactive oxygen species (ROS) generation and deoxyribonucleic acid (DNA) damage. Cell viability and Western blotting analyses were employed to evaluate the cellular response to EGL and $H_2O_2$ in C2C12 cells. Transfection with nuclear factor erythroid 2-related factor 2 (Nrf2)-specific small interfering ribonucleic acid (siRNA) was conducted to understand the relationship between Nrf2 expression and $H_2O_2$-induced growth inhibition. Results: The results showed that EGL effectively inhibited $H_2O_2$-induced growth and the generation of ROS. EGL markedly suppressed $H_2O_2$-induced comet-like DNA formation and phosphorylation of histone H2AX at serine 139 ($p-{\gamma}H2AX$), a widely used marker of DNA damage, suggesting that EGL prevented $H_2O_2$-induced DNA damage. Furthermore, the EGL treatment effectively induced the expression of Nrf2, as well as heme oxygenase-1 (HO-1), with parallel phosphorylation and nuclear translocation of Nrf2 in the C2C12 myoblasts. However, zinc protoporphyrin IX, a HO-1 inhibitor, significantly abolished the protective effects of EGL against $H_2O_2$-induced accumulation of ROS and reduced cell growth. Notably, transient transfection with Nrf2-specific siRNA attenuated the cytoprotective effects and HO-1 induction by EGL, indicating that EGL induced the expression of HO-1 in an Nrf2-dependent manner. Conclusion: Collectively, these results demonstrate that EGL augments the cellular anti-oxidant defense capacity through activation of Nrf2/HO-1, thereby protecting C2C12 myoblasts from $H_2O_2$-induced oxidative cytotoxicity.

However, decreased GSIS was not recovered even in the presence of CoPP.</P><P><B>Conclusion</B></P><P>Our data suggest that CoPP-induced HO-1 up-regulation results in protection from high glucose-induced apoptosis in INS-1 cells; however, glucose stimulated insulin secretion is not restored.</P>

Genetic Diversity of Korean Rice Breeding Parents as Measured by DNA Fingerprinting with Simple Sequence Repeat (SSR) Markers

Song,Moon-Tae,Lee,Jeom-Ho,Lee,Sang-Bok,Cho,Youn-Sang,Ku,Ja-hwan,Seo,Kyoung-In,Choi,Seong-ho,Hwang,Heung-Goo 한국자원식물학회 2003 Plant Resources Vol.6 No.1

Molecular markers are useful tools for evaluating genetic diversity and determining cultivar identity. Present study was conducted to evaluate the genetic diversity within a diverse collection of rice accessions used for Korean breeding programs. Two hundred eighty-seven rice cultivars, composed of temperate japonica, tropical japonica, indica, and Tongil-type of Korean crossing parents were evaluated by means of 15 simple sequence repeat (SSR) markers. A total of 99 alleles were detected, and the number of alleles per marker ranged from 4 to 11, with an average of 6.6 per locus. Polymorphism information content (PIC) for each of the SSR markers ranged from 0.2924 to 0.8102 with an average of 0.5785. These results, with the result that use of only 15 SSR markers made all rice cultivars examined could be uniquely distinguished, imply the efficiency of SSR markers for analysis of genetic diversity in rice. Cluster analysis was performed on similar coefficient matrics calculated from SSR markers to generate a dendogram in which two major groups corresponding to japonica (Group I) and indica and Tongil type rice (group II) with additional subclasses within both major groups. The narrowness of the Korean breeding germplasm was revealed by the fact that most of the Korean-bred and Japan-bred temperate japonica cultivars were concentrated into only 2 of the sub-group I-1 (143 cultivars) and I-2 (58 cultivars) among six sub-groups in major group of japonica. This is because of the japonica accessions used in this study was a very closely related ones because of frequent sharing of the crossing parents with similar genetic background with synergy effect of the inherited genetic difference between indica and japonica. A rice breeding strategy with the use of molecular markers was discussed for overcoming of genetic vulnerability owing to this genetic narrowness.

Objects : Recent studies of psychosocial adjustment after hospitalization have found that the combination of maintenance antipsychotic drug treatment and psychosocial treatment including psychoeducational program are highly predictive of social rehabilitation and reduction of subsequent relapse. Two groups of patients with refractory chronic schizophrenia were preliminarily compared to determine the effect of a psychosocial treatment program on the quality of life in refractory chronic schizophrenics in an open comparative trial. Methods : One group(N=11) was assigned to approximately six months of the psychosocial treatment program(including psychoeducation program and activity program such as interpersonal relationship program, social skill training, self management program, outings, etc), in a group format, twice a week and a fixed maintenance dosage of clozapine ; while scale(QLS) was used to provide an objective measure of changes in patient's psychosocial functioning and a general assessment of psychopathology was made using the Brief Psychiatric Rating Scale(BPRS). Results : Both BPRS total positive score and the QLS total score, especially in the intrapsychic foundation factor of the scale showed a statistically significant improvement in the psychosocial treatment group. But there was no significant change in both BPRS and QLS scores over a 6-month period in the non-psychosocial treatment group. A significant negative correlation was found between the negative symptom and changes of QLS total, instrumental role and common object and activities scores respectively after receiving a 6-month of the psychosocial treatment program. Conclusion : These results suggest that a psychosocial treatment program including the integration of psychoeducation and a skill training oriented activity program serve as an outpatient treatment modality to improve the quality of the life in refractory chronic schizophrenia. To further clarify the effect of psychosocial treatment in chronic schizophrenia, a randomized trial should be done.

Tetrodotoxin is a neurotoxin produced by about 90 species of puffer fish and causes paralysis of central nervous system and peripheral nerves by blocking the movement of all monovalent cation. Ingestion of tetrodotoxin produces clinical manifestations such as paresthesias(within 10-45 min), vomiting, lightheadedness, salivation, muscle twitching, dysphagia, difficulty in speaking, convulsion and death that expressed by cardiopulmonary arrest with loss of brain stem reflex sometimes. Tetrodotoxin prevents or delays ischemia induced neuronal death by way of following 3 mechanisms. Firstly, it reduces the energy demand of the brain tissues. Secondly, it delays or even prevents anoxic depolarization. Finally, it deminishes ischemia induced cell swelling and cerebral edema. We report a case of puffer fish poisoning which presented with cardiopulmonary arrest and loss of brain stem reflex, but completely recovered by aggressive cardiopulmonary resuscitation.
