목 적: 본 연구의 목적은 한국인 남자 알코올 의존 환자의 기질적 특성을 Temperament and Character Inventory(TCI)를 이용하여 조사하는 것이다. 방 법: DSM-Ⅳ 진단 기준에 맞는 알코올 의존 환자 30명과 정상인 36명을 대상으로 연구학적 특성을 조사하고, 기질적 특성을 한글판 TCI를 이용하여 조사하였다. 모든 대상자의 나이는 30~60세였다. 결 과: 1) 두 군간 평균 나이는 유의한 차이가 없었으나, 교육 정도와 결혼을 유지하고 있는 비율 및 취업률은 알코올 의존군이 정상 대조군에 비해 유의하게 낮았다. 2) 알코올 의존군에서는 정상 대조군에 비해 Harm Avoidance(HA) 점수와 Self-transcendence(ST)점수는 유의하게 높았으며, Self-directiveness(SD)점수는 유의하게 낮았다. 3) 알코올 의존군 내에서의 각 척도들 간의 상관관계는, HA와 SD 점수, HA와 Persistence(PE) 점수, ST와 SD 점수는 각각 유의한 음의 상관관계, ST와 PE 점수, SD 점수와 Cooperativeness(CO) 점수, Reward Dependence(RD)와 CO 점수는 양의 상관관계를 보였다. 결 론: 이러한 본 연구의 결과는 한국인 남성에서 수줍음을 잘 타며, 걱정도 많고, 염세적이고 쉽게 피로해지는 기질적 특성이 알코올 의존과 연관성이 있음을 의미한다. Objectives : The purpose of this study was to assess the temperament of male parients with alcohol dependence. Methods : The subjects were 30 patients who met DSM-Ⅳ criteria for alcohol dependence and 36 normal controls. All subjects completed Temperament and Character Inventory(TCI) which was developed by Cloninger. Results : 1) The educational level, marital status, and occupation in alcohol dependence group were significantly lower than those of normal control group, but there was no difference in the age between two groups. 2) Among the scores of TCI, the score of harm avoidance(HA) and self-transcendence(ST) were significantly higher in the alcohol dependence group than in the normal control group. 3) In the alcohol dependence group, a significant negative correlation among the scores of TCI was between HA and SD, HA and Persistence(PE), ST and SD, and positive correlation between ST and PE, SD and Cooperativeness(CO), Reward Dependence(RD) and CO. Conclusion : These results suggest that shy, fearful, pessimistic and fatigable temperament are related to developing alcohol dependence in Korean males.

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.

Identification of Receptor-like Protein for Fructose-1,6-bisphosphatase on Yeast Vacuolar Membrane

Ko, Je-Sang Korean Society for Biochemistry and Molecular Biol 2000 Journal of biochemistry and molecular biology Vol.33 No.6

In yeast the key gluconeogenic enzyme, fructose-1,6-bisphosphatase (FBPase), is selectively targeted from the cytosol to the lysosome (vacuole) for degradation when glucose starved cells are replenished with glucose. The pathway for glucose induced FBPase degradation is unknown. To identify the receptor-mediated degradation pathway of FBPase, we investigated the presence of the FBPase receptor on the vacuolar membrane by cell fractionation experiments and binding assay using vid mutant (vacuolar import and degradation), which is defective in the glucose-induced degradation of FBPase. FBPase sedimented in the pellets from vid24-1 mutant after centrifugation at $15,000{\times}g$ for 15 min, suggesting that FBPase is associated with subcellular structures. Cell fractionation experiments revealed that FBPase is preferentially associated with the vacuole, but not with other organelles in vid24-1. FBPase enriched fractions that cofractionated with the vacuole were sensitive to proteinase K digestion, indicating that FBPase is peripherally associated with the vacuole. We developed an assay for the binding of FBPase to the vacuole. The assay revealed that FBPase bound to the vacuole with a Kd of $2.3{\times}10^6M$. The binding was saturable and specific. These results suggest that a receptor for FBPase degradation exists on the vacuolar membrane. It implies the existence of the receptor-mediated degradation pathway of FBPase by the lysosome.

Partial nerve injury is the main cause of neuropathic pain disorders in humans. Acupuncture has long been used to relieve pain. It is known to relieve pain by controlling the activities of the autonomic nervous system. Although the mechanism of neuropathic pain and analgesic effects of electroacupuncture (EA) have been studied in a rat model system, its detailed mechanism at the molecular level remains unclear. To identify genes that might serve as either markers or explain these distinct biological functions, a cDNA microarray analysis was used to compare the expression of 8,400 genes among three sample groups. Messenger RNAs that were pooled from the spinal nerves of 7 normal, 7 neuropathic pain, and 7 EA treatment rat models were compared. Sixty-eight genes were differentially expressed more than 2-fold in the neuropathic rat model when compared to the normal, and restored to the normal expression level after the EA treatment. These genes are involved in a number of biological processes, including the signal transduction, gene expression, and nociceptive pathways. Confirmation of the differential gene expression was performed by a dotblot analysis. Dot-blotting results showed that the opioid receptor sigma was among those genes. This indicates that opioid-signaling events are involved in neuropathic pain and the analgesic effects of EA. The potential application of these data include the identification and characterization of signaling pathways that are involved in the EA treatment, studies on the role of the opioid receptor in neuropathic pain, and further exploration on the role of selected identified genes in animal models.

<i>Sipjeondaebo-tang</i> Alleviates Oxidative Stress-Mediated Liver Injury through Activation of the CaMKK2-AMPK Signaling Pathway

Park, Sang Mi,Kim, Sung Woo,Jung, Eun Hye,Ko, Hae Li,Im, Chae Kwang,Lee, Jong Rok,Byun, Sung Hui,Ku, Sae Kwang,Kim, Sang Chan,Park, Chung A,Kim, Kwang Joong,Cho, Il Je Hindawi 2018 Evidence-based Complementary and Alternative Medic Vol.2018 No.-

<P><I>Sipjeondaebo-tang</I> (SDT) is used frequently as a herbal prescription to treat deficiency syndromes in traditional Korean medicine. We investigated the hepatoprotective effects of SDT against oxidative stress and attempted to clarify the underlying molecular mechanisms. SDT pretreatment reduced arachidonic acid (AA) plus iron-mediated cytotoxicity in a concentration-dependent manner and prevented changes in apoptosis-related protein expression. In addition, SDT pretreatment significantly reduced glutathione depletion, hydrogen peroxide production, and mitochondrial dysfunction via treatment with AA plus iron. SDT increased the phosphorylation of AMP-activated protein kinase (AMPK) in accordance with the phosphorylation of Ca<SUP>2+</SUP>/calmodulin-dependent protein kinase kinase 2 (CaMKK2). Experiments using an AMPK chemical inhibitor (Compound C) or CaMKK2 chemical inhibitor (STO-609) suggested that the CaMKK2-AMPK signaling pathway contributes to SDT-mediated protection of mitochondria and cells. Moreover, administration of SDT for 4 consecutive days to mice significantly reduced the alanine aminotransferase and aspartate aminotransferase activities induced by carbon tetrachloride, and the numbers of degenerated hepatocytes, infiltrated inflammatory cells, nitrotyrosine-positive cells, and 4-hydroxynonenal-positive cells in liver tissue. Therefore, SDT protects hepatocytes from oxidative stress via CaMKK2-dependent AMPK activation and has the therapeutic potential to prevent or treat oxidative stress-related liver injury.</P>

Genipin inhibits allergic responses in ovalbumin-induced asthmatic mice

Ko, Je-Won,Shin, Na-Rae,Park, Sung-Hyeuk,Cho, Young-Kwon,Kim, Jong-Choon,Seo, Chang-Seob,Shin, In-Sik ELSEVIER 2017 INTERNATIONAL IMMUNOPHARMACOLOGY Vol.53 No.-

<P><B>Abstract</B></P> <P>Genipin is a natural compound isolated from the fruit of <I>Gardenia jasminoides</I> with various pharmacological effects. In this study, we investigated whether genipin effectively alleviates allergic responses in a murine model of ovalbumin (OVA)-induced asthma. The mice were administered an intraperitoneal injection of OVA on day 0 and 14 to boost the immune response; genipin was then administered from day 18 to 23 by oral gavage. On days 21 to 23, mice were OVA-challenged using am ultrasonic nebulizer, and airway hyperresponsiveness (AHR) was determined on day 24 by plethysmography. Genipin significantly reduced the inflammatory cell count in bronchoalveolar lavage fluids (BALF) and AHR, which were accompanied by lower interleukin-5 (IL-5), IL-13 and OVA-specific immunoglobulin (Ig) E levels in the BALF or serum from OVA-induced asthmatic mice. In histology, genipin significantly decreased airway inflammation and mucus hypersecretion in OVA-induced asthmatic mice. Additionally, genipin inhibited OVA-induced increases in the expression of inducible nitric oxide synthase and cyclooxygenase-2 proteins. Further, genipin reduced the activity and protein levels of matrix metalloproteinase-9 in lung tissue from OVA induced asthmatic mice. Overall, genipin effectively alleviated the asthmatic inflammatory response in an OVA-induced asthmatic model. Therefore, our results suggest that genipin has therapeutic potential for treating asthma.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Effects of genipin on ovalbumin (OVA)-induced asthmatic mice </LI> <LI> Genipin decreased airway hyperresponsiveness and eosinophilia in asthmatic mice </LI> <LI> Genipin reduced IL-5, IL-13 and OVA-specific IgE in asthmatic mice </LI> <LI> Genipin suppressed airway inflammation and mucus production in asthmatic mice </LI> <LI> Genipin inhibited iNOS, COX-2 and MMP-9 in lung tissue from asthmatic mice </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
