  • Objectives : This study aimed to clarify the relationship between the Oriental medical diagnosis and arteriosclerosis by measuring carotid-ankle vascular index(CAVI) in acute cerebral infarction patients. Method : One hundred thirty-one subjects were recruited from the patients admitted to the Internal Medical Department at Kyunghee University Oriental Medical Center from April 2007 to August 2008. We sorted cerebral infarction patients and assessed one hundred fourteen patients' CAVI data. We diagnosed dampness-phlegm by Oriental medical diagnosis and evaluated stroke type by single or multiple infarctions. then, we analyzed their characteristics with type of stroke, risk factor, lifestyle, metabolic syndrome and dampness-phlegm diagnosis. Result : 1. On the demographic variables of the patients, age, hypertension, hyperlipidemia, multiple infarction group and metabolic syndrome and dampness-phlegm group were significantly higher in the high CAVI score group than in the control. 2. According to the significant difference in the dampness-phlegm group, we analyzed dampness-phlegm related index for pattern identifications by CAVI score. As a result, dark circles, insomnia, headache, white coating tongue. slippery pulse, and rough pulse were significantly higher in the high CAVI score group then in the control. 3. In multivariate analysis, age, hypertension, multiple infarction and dampness-phlegm groups showed a close relationship with the high CAVI score group. Conclusions : According to the analysis, significance between dampness-phlegm diagnosed patients group and high CAVI score were clarified. Moreover, multiple location infarctions also have a relationship with high CAVI score in cerebral infarction patients. These results can be utilized in the future as a basis material.

  • Purpose : This study aimed to investigate the effects of 12 weeks of resistance exercise on body composition, physical strength, blood lipids, and insulin. Methods : The study was conducted on 24 elderly women divided into two groups: 12 subjects in an exercise group and 12 subjects in a control group. Resistance exercise was performed for 50 minutes a day, three times a week, for the duration of 12 weeks, and body composition, physical strength, blood lipids, and insulin were measured before and after the subjects completed the program. For the statistical analysis, the mean and standard deviation (M±SD) of each variable were calculated using SPSS version 20, and a paired t-test and two-way repeated ANOVA were conducted to test for the differences before and after the resistance exercise. All significant levels were set to α=.05 as a result of the experiment. Results : Changes in body composition after the 12-week resistance exercise program did not show any significant difference based on the comparison between the groups, but when noting the values for body fat percentage and body in the control group before and after, a significant difference was shown in fat mass (p<.05). As for changes in physical fitness, significant differences appeared in flexibility, muscle strength, and stenotic force (p<.01) when the groups were compared. Regarding pre- and post-values within each group concerning flexibility within the exercise group, significant differences were shown in gender (p<.001), muscle strength (p<.05), (p<.01), muscle earth strength, equilibrium (p<.01), stenosis force, and cardiopulmonary earth force (p<.001). Also, comparisons between populations in changes in blood lipids the values before and after in each group, significant differences in glucose (p<.05) and insulin (p<.05) were shown in the exercise group. When comparing the values before and after in each population, a significant difference was shown in the control group (p<.05). Conclusion : When all the results were integrated, the 12-week resistance exercise program was found to enhance physical strength (flexibility, muscle strength, and coordination) and improve the blood sugar levels of elderly women. In particular, resistance exercise is believed to lower the prevalence of obesity, type 2 diabetes mellitus, and metabolic diseases by having a positive effect on insulin. Further studies are suggested to verify the effect on body composition and blood lipids by setting up a variety of exercise treatment methods (including subjects, exercise periods, exercise plans, and exercise intensity focuses).

  • 목 적 : 소아기의 비만은 성인기의 비만여부와 상관없이 대사증후군과 심근경색증의 유병률을 높이는 것으로 알려져 있으며 또한, 직접적인 원인으로 작용할 수 있다고 보고되었다. 그리고, hs-CRP은 장래의 심근경색을 예측할 수 있는 인자이며 특히 비만시에 유의하게 증가되는 것으로 보여 성인에서는 임상적으로 유용하게 쓰이기 시작하였으나, 소아에서의 연구는 미흡한 실정이다. 저자는 소아 비만에서의 hs-CRP의 증가에 대해 조사하고자 하였다. 방 법 : 14세의 소년들을 28명의 비만아군(BMI $29.61{\pm}3.29kg/m^2$)과 93명의 대조군(BMI $18.99{\pm}2.21kg/m^2$)으로 선정하여 연구를 시행하였다. 혈중 CRP 농도는 the high sensitive latex turbidimetric immunoassay를 사용하여 측정하였으며 급성 감염의 영향을 배제하기 위해 측정값이 0.3 mg/dL 미만인 경우만을 실험대상으로 채택하였다. 비만아군과 대조군에 대해서 각각의 hs-CRP의 분포를 알아보았으며 hs-CRP와 BMI, 혈압, 혈중 지질 농도의 연관성에 대해 분석하였다. 결 과 : hs-CRP 농도는 비만아군이 대조군에 비해 통계학적으로 유의하게 높은 측정값을 보였다($0.104{\pm}0.075$ vs. $0.054{\pm}0.005mg/dL$). 비만아군은 대조군에 비해 BMI, 수축기혈압, 이완기혈압, apolipoprotein B, 죽종형성지수와 triglyceride에서 높은 결과치를 나타내었다. 단순회귀분석상에서 hs-CRP는 BMI, 이완기혈압, apolipoprotein E, 죽종형성지수, TG와 통계학적으로 유의한 연관성을 나타내었으나, 다중회귀분석상에서는 BMI와 apolipoprotein E만이 강력한 연관성을 보여주었다. 결 론 : 비만아군은 대조군에 비해 혈중 hs-CRP가 높게 나타났으며 더불어 혈압의 상승과 지질대사이상을 동반하는 경향이 증가함을 보여주었다. 그리고, hs-CRP는 BMI와 apolipoprotein E와 강력한 연관성을 나타내었다. 이 결과들은 비만과 관련된 대사증후군이 소아시기에 이미 시작될 수 있음을 시사하는 것으로 볼 수 있다.

  • 생쥐의 난자는 특별한 첨가물이나 난구세포 없이 체외 배양해도 성숙율이 높은 반면 돼지 난자의 체외성숙율은 매우 낮다. 본 연구는 이러한 차이의 원인을 연구하기 위하여 생쥐와 돼지 난자의 에너지 생성에 관여하는 유전자인 malate dehydrogenase(Mor2)의 기능을 RNAi를 이용하여 비교 분석하였다. 생쥐와 돼지 각각의 Mor2 double-stranded RNA(dsRNA)를 제작하고, 생쥐는 난구세포를 제거한 미성숙(GV) 난자의 세포질에 mMor2 dsRNA를 미세 주입한 후 16시간 동안 배양하였고, 돼지는 난구세포를 제거하거나(DO) 혹은 그대로인 상태(COCs)로 pMor2 dsRNA를 미세 주입한 후 48시간 동안 배양하였다. 사용한 배양액은 M199에 10%의 porcine follicular fluid, pyruvate, p-FSH, EGF, cystein, estradiol-$17{\beta}$ 등이 첨가된 배양액을 사용하였고, 배양 후 난자의 형태학적 변화를 관찰하고, Mor2 mRNA양의 변화를 RT-PCR로 확인하여 RNAi 결과, 염기서열 특이적으로 Mor2 발현이 억제됨을 확인하였다. 돼지 난자의 pMor2 RNAi 결과, DO 난자에서는 약 58%의 난자가 MI에서 성숙이 억제되었으나, COCs에선 84.4%가 MII로 성숙하는 것을 볼 수 있었다. 이는 돼지의 난구세포가 난자 성숙에 매우 중요하며, 특히 malate 공급에 관여할 것임을 시사한다. 선행 연구 Mor2 RNAi 결과, 생쥐는 GV에서, 본 연구에서 돼지는 MI에서 성숙이 정지되었기 때문에 이러한 차이가 배양액의 차이인지 다시 mMor2 RNAi 후 생쥐 난자를 M199 배양액에 16시간 동안 배양한 후 성숙율을 관찰하였더니 MII로의 성숙율은 62%로 대조군과 비교하여 큰 차이가 없었다(non-injected: 76.8%, buffer-injected: 73.3%). 이는 mMor2 RNAi 결과가 배양액의 조성에 의해 극복될 수 있음을 보여준 결과다. 생쥐와 돼지에서 서로 다른 대사과정을 갖고 있음은 바로 이 두 종에서의 체외성숙율 차이의 원인이 될 수 있을 것이며, 앞으로 두 종에서의 난자와 난구세포간의 상호작용 및 대사 경로 등에 관한 심도 깊은 비교 분석 연구를 통하여 돼지의 체외성숙율을 증가시킬 수 있는 배양 시스템의 개발이 가능할 것으로 기대된다.

  • Background: In cancer cells, autophagy is generally induced as a pro-survival mechanism in response to treatment-associated genotoxic and metabolic stress. Thus, concurrent autophagy inhibition can be expected to have a synergistic effect with chemotherapy on cancer cell death. Monensin, a polyether antibiotic, is known as an autophagy inhibitor, which interferes with the fusion of autophagosome and lysosome. There have been a few reports of its effect in combination with anticancer drugs. We performed this study to investigate whether erlotinib, an epidermal growth factor receptor inhibitor, or rapamycin, an mammalian target of rapamycin (mTOR) inhibitor, is effective in combination therapy with monensin in non-small cell lung cancer cells. Methods: NCI-H1299 cells were treated with rapamycin or erlotinib, with or without monensin pretreatment, and then subjected to growth inhibition assay, apoptosis analysis by flow cytometry, and cell cycle analysis on the basis of the DNA contents histogram. Finally, a Western blot analysis was done to examine the changes of proteins related to apoptosis and cell cycle control. Results: Monensin synergistically increases growth inhibition and apoptosis induced by rapamycin or erlotinib. The number of cells in the sub-$G_1$ phase increases noticeably after the combination treatment. Increase of proapoptotic proteins, including bax, cleaved caspase 3, and cleaved poly(ADP-ribose) polymerase, and decrease of anti-apoptotic proteins, bcl-2 and bcl-xL, are augmented by the combination treatment with monensin. The promoters of cell cycle progression, notch3 and skp2, decrease and p21, a cyclin-dependent kinase inhibitor, accumulates within the cell during this process. Conclusion: Our findings suggest that concurrent autophagy inhibition could have a role in lung cancer treatment.

  • Objective: The Fusarium mycotoxins of deoxynivalenol (DON) and zerolenone (ZEN) cause health hazards for both humans and farm animals. Therefore, the main intention of this study was to reveal DON and ZEN effects on the mRNA expression of pro-inflammatory cytokines and other immune related genes in the liver of piglets. Methods: In the present study, 15 six-week-old piglets were randomly assigned to the following three different dietary treatments for 4 weeks: control diet, diet containing 8 mg DON/kg feed, and diet containing 0.8 mg ZEN/kg feed. After 4 weeks, liver samples were collected and sequenced using RNA-Seq to investigate the effects of the mycotoxins on genes and gene networks associated with the immune systems of the piglets. Results: Our analysis identified a total of 249 differentially expressed genes (DEGs), which included 99 upregulated and 150 downregulated genes in both the DON and ZEN dietary treatment groups. After biological pathway analysis, the DEGs were determined to be significantly enriched in gene ontology terms associated with many biological pathways, including immune response and cellular and metabolic processes. Consistent with inflammatory stimulation due to the mycotoxin-contaminated diet, the following Kyoto encyclopedia of genes and genomes pathways, which were related to disease and immune responses, were found to be enriched in the DEGs: allograft rejection pathway, cell adhesion molecules, graft-versus-host disease, autoimmune thyroid disease (AITD), type I diabetes mellitus, human T-cell leukemia lymphoma virus infection, and viral carcinogenesis. Genome-wide expression analysis revealed that DON and ZEN treatments downregulated the expression of the majority of the DEGs that were associated with inflammatory cytokines (interleukin 10 receptor, beta, chemokine [C-X-C motif] ligand 9), proliferation (insulin-like growth factor 1, major facilitator superfamily domain containing 2A, insulin-like growth factor binding protein 2, lipase G, and salt inducible kinase 1), and other immune response networks (paired immunoglobulin-like type 2 receptor beta, Src-like-adaptor-1 [SLA1], SLA3, SLA5, SLA7, claudin 4, nicotinamide N-methyltransferase, thyrotropin-releasing hormone degrading enzyme, ubiquitin D, histone $H_2B$ type 1, and serum amyloid A). Conclusion: In summary, our results demonstrated that high concentrations DON and ZEN disrupt immune-related processes in the liver.

  • Objectives : AMP-activated protein kinase (AMPK) is a key metabolic regulator that reduces lipogenesis. AMPK is mainly activated via phosphorylation of liver kinase B (LKB) 1 under energy stress. Here, we highlighted the anti-obesity effect and underlying mechanism of Coix lacryma-jobi var. mayuen Stapf sprout water extract (CSW) sprout extract in connection with the LKB1/AMPK signaling pathway. Methods : C57BL/6 mice (20~25 g) fed HFD to induce obesity and at the same time administered CSW 100 mg/kg (CSWL; (CSWL; CSW low concentration) or CSW 200 mg/kg (CSWH; CSW high concentration) or Garcinia extract (Garcinia) 200 mg/kg orally for 6 weeks. Body weight and food intake were measured at the same time each day. After 6 weeks of CSW administration, liver tissue and serum were obtained through an autopsy. After the end of the experiment, biochemical analysis (triglycerides (TG), total cholesterol (TC), HDL-cholesterol, and LDL-cholesterol) was performed on the serum. And then, protein levels related to TG and TC synthesis were measured through western blot analysis in liver tissue. Results : As a result, serum TG, TC, and LDL-cholesterol levels were significantly increased in the control group and significantly decreased in the CSW administration group. On the other hand, the HDL-cholesterol level was increased in the CSW-administered group. And as a result of Western blot analysis, CSW significantly increased the phosphorylation of LKB1 & AMPK, and remarkably decreased the expression of factors related to TG and TC synthesis. Conclusions : Our findings suggest that CSW influences the TG and TC synthesis to positively affect HFD-induced obesity in C57BL/6 mice.

  • 목적: 뮤코지방증 유형 II와 III은 리소좀 효소인N-acetylglucosaminyl-1-phosphotransferase (UDP-N-acetylglucosamine, GlcNAc-phospho-transferase)의 결손에 의해 초래되며, 상염색체 열성으로 유전되는 질환이다. ${\alpha}/{\beta}/{\gamma}$ subunit로 구성되는 이 효소의 결핍으로 인해 리소좀으로 운반되는 수십 종류의 효소들에 mannose-6-phosphate(M6P)를 부착하는 과정에 장애가 생겨 분해되지 않은 물질이 축적되어 질병이 초래된다. 이 질환에 있어서 산전 진단과 유전 상담을 위해서는 상기 효소의 해당 유전자가 밝혀져 있어야 하나, 현재 이 효소의 ${\gamma}$ subunit를 암호화하는 유전자가 GNPTAG에 해당된다고 밝혀져 있을 뿐 ${\alpha}/{\beta}$ subunit을 암호화하는 GNPTA에 해당하는 유전자는 밝혀져 있지 않고 돌연변이 역시 보고된 적이 없다. 본 연구는 리소좀 효소의 인산화에 관여하는 N-acetylglucosamine-1-phospho-transferase의 결함이 있는 환자의 섬유아세포를 이용하여 리소좀 연관 신규 유전자를 찾아내고, 그 유전자를 대상으로 돌연변이를 규명하고자 하였다. 방법: 이를 위해 5명의 환자와5명의 연령, 성별이 일치하는 정상아의 섬유아세포를 계대 배양하여 이 세포를 이용하여 수행한 subtractive hybridization을 통해 신규 유전자를 탐색하고, 신규 유전자를 대상으로 돌연변이 분석을 수행하였다. 결과: 연구 결과 환자에서 발현이 증가된 유전자 73개와 발현이 감소된 유전자 50개를 밝혀냈다. 분석된 유전자 중에서 MGC4170이환자에서는 발현되지 않으나 정상인에서는 발현됨을 발견하였고, 이 유전자가 아직 밝혀지지 않은 GNPTA로 확인되어 환자를 대상으로 돌연변이 분석을 시행하였다.분석 결과 기존에 돌연변이가 보고되었던 GNPTAG에는 돌연변이가 없었으나, MGC4170에는 7개의 돌연변이가 발견되었다. 본 연구는 GlcNAc-phosphotransferase의 ${\alpha}/{\beta}$ subunit에 해당되는 MGC4170의 최초 돌연변이 보고이다. 결론: 본 연구를 통해 뮤코지방증 II형과 III형에서 발현되는 유전자 군을 파악할 수 있었으며, 동시에 MGC4170 돌연변이를 규명함으로써 이 질환의 병리 기전 연구와 산전 진단에 기여하고자 한다.

  • L-Carnitine is an antioxidant for the transport of fatty acids in mitochondria and breakdown of lipids for metabolic energy. Some studies have suggested that carnitine improves sperm motility in mammals. The objective of this study was to investigate the effect of L-carnitine on the characteristics in fresh semen of miniature pigs. The collected fresh semen was stored in modena B medium with L-carnitine (0, 1.0, 2.0, and 4.0 mg/ml) for 10 days at $18^{\circ}C$. The semen quality of viability, acrosome reaction and mitochondria integrity was analyzed on 0, 3, 7, and 10 day of semen storage. The percentages of live and dying sperm were not different among treatment groups with different concentrations of L-carnitine during the storage period. In acrosome reaction analysis, when the sperm stored for 7 day, the percentages of live sperm with acrosome reaction were significantly (p<0.05) lower in 1 ($9.0{\pm}0.9%$), 2 ($7.6{\pm}0.2%$) or 4 mg/ml ($7.9{\pm}0.8%$) L-carnitine-treated groups than the control group (0 mg/ml L-carnitine) ($11.12{\pm}0.2%$). However, there were no difference in percentages of live sperm with acrosome reaction for 3 and 10 days of storage with each concentrations of L-carnitine. When sperm was stored for 3 and 10 days, the percentages of live sperm with mitochondria integrity were significantly higher in 2 mg/ml of L-carnitine-treated group than control group (p<0.05). In conclusion, the L-carnitine has a positive effect on acrosome reaction and mitochondria integrity in liquid state of fresh semen in miniature pigs.

  • It has been reported that CLA decreases fat deposition in vivo and in vitro experiments. Among CLA isomers, c9t11 and t10c12 have been shown to exert active biological activities. For example, t10c12 reduces body weight and increases lean body mass, whereas, c9t11 has little effect on body fattness. However, the underlying molecular mechanism for the anti-obesity action of CLA isomers are not well understood. The purpose of this study was to examine the effects of t10c12 and c9t11 on lipid accumulation, cell proliferation, cell death and the expression levels of Ucp genes which are proposed as targets for anti-obesity in 3T3-L1 preadipocytes. Isomers of CLA at 50$\mu$M were added into preadipocyte differentiation medium for 3, 6 and 9days. Control cells received only the vehicle in the differentiation medium. Cytochemical analyses for lipid accumulation, cell proliferation and apotosis were carried out to compare lipidogenesis and cellular activity. RT-PCR analysis of GAPDH, Ucp 2,3 and 4 were also performed to find any modulatory effects of CLA isomers on the metabolic genes. Lipid accumulation indicated by Oil Red-O staining was inhibited in CLA isomers as compared to the control. T10c12 isomer showed less lipidogenesis than c9t11 did. A decrease occurred in CLA isomers as shown by BrdU incorporation. Apotosis has occured at higher level in t10c12 when compared to that of t9c11. Ucp 2, 3 and 4 genes were also upregulated in CLA isomers. T10c12 showed higher level of Ucp gene expressions than the c9t11 did. The biological activities of CLA isomers were also found to be different during differentiation of 3T3-L1 preadipocytes, suggesting that different isomers may be active in certain stage of lipidogenesis. The results indicate that both c9t11 and t10c12 CLA isomers decrease lipidogenesis, inhibit cell proliferation, increase cell death and upregulate in Ucp gene expressions during 3T3-L1 preadipocyte differentiation. T10c12 isomer was more effective than c9t11 in overall anti-obesity activity.
