  • Ziziphus jujuba Mill. (ZJM), a traditional folk medicine and functional food in South Korea and China, has been reported to having pharmacological activities against anti-cancer, anti-oxidative, and anti-obesity. However, the effect of ZJM related to myoblast differentiation has not been known. In this study, we investigated the effects and mechanism of ZJM on myogenic differentiation of C2C12 cells. ZJM promotes myogenic differentiation and elevates the formation of multinucleated myotube compared to the control group. ZJM significantly increased the mRNA and protein expression of MyHC1, myogenin and MyoD in dose- and time-dependent manner. Interestingly, ZJM significantly inhibited the mRNA and protein expression of protein degradation markers, atrogin-1 and MuRF-1, in dose- and time-dependent manner. Taken together, our data suggest that ZJM is a potential functional candidate for muscle growth and strength by promoting myogenic differentiation.

  • Thailand is becoming an aging society, this presenting as a serious problem situation especially regarding health. Chronic diseases found frequently in the elderly may be related to dietary intake and life style. Surin province has been reported as a risk area for liver fluke with a high incidence of cholangiocarcinma especially in the elderly. Therefore, this study aimed to determine the nutritional status and associated factors among elderly in Surin province, northeast of Thailand. A community-based cross-sectional study was conducted among 405 people aged 60 years and above, between September 2012 and July 2014. The participants were selected through a randomized systematic sampling method and completed a pre-designed questionnaire with general information, food recorded, weight, height, waist circumference, and behavior regarding to food consume related to liver fluke infection. The data were analyzed using descriptive statistics and Spearman's rank correlation coefficients. The majority of participants was female (63.5%), age between 60-70 years old (75.6%), with elementary school education (96.6%), living with their (78.9%), and having underlying diseases (38.3%). Carbohydrate (95.3%) was need to improve the consumption. The participants demonstrated under-nutrition (24.4%), over-nutrition (16.4%), and obesity (15.4%). Elderly had a waist circumference as the higher than normal level (34.0%). Gender, female, age 71-80 years old, elementary school and underlying diseases were significantly associated with poor nutritional status. The majority of them had a high knowledge (43.0%), moderate attitude (44.4%), and moderate practice (46.2%) regarding food consumption related to liver fluke infection. In conclusion, these findings data indicated that elderly age group often have an under- or over-nutritional status. Carbohydrate consumption needs to be improved. Some elderly show behavior regarding food consumption that is related to liver fluke infection hat needs to be improved, so that health education pertaining good nutrition is required.

  • 길경(桔梗, Platycodon grandiflorum)은 도라지의 뿌리로 항염증, 항알러지, 면역 반응, 당뇨, 고지혈증 및 항암 효과 등을 가지고 있는 것으로 알려져 있다. 하지만 길경의 항암 효과에 대한 연구는 미미하며, 길경이 유발하는 autophagy에 대한 연구는 되어 있지 않다. 본 연구에서는 HCT-116 대장암 세포주에서 길경 추출물이 autophagy와 apoptosis를 유발하면서 세포 성장을 억제하는지의 여부를 조사하였다. 길경 추출물은 농도 및 시간의존적으로 세포의 증식을 억제하였으며, 길경 추출물에 의해 나타나는 apoptosis는 caspase의 활성이 부분적으로 관여되어 있음을 알 수 있었다. 또한, 길경 추출물의 처리는 autophagy에 의해 나타나는 공포를 형성하면서 autophagy와 관련되어 있는 여러 단백질의 발현 조절 및 LC3 단백질의 축적이 동반되었다. 길경 추출물에 의해 유도되는 autophay와 apoptosis의 관계를 알아보기 위해서 3-MA나 bafilomycin A1을 처리하여 autophagy를 억제하였을 때 apoptosis가 유의적으로 증가됨을 알 수 있었다. 흥미롭게도 bafilomycin A1을 처리한 결과에서 길경 추출물에 의한 세포성장 억제가 뚜렷하게 회복되는 양상을 보였다. 따라서 본 연구의 결과는 HCT-116 세포에서 길경 추출물에 의해 유도된 autophagy는 세포 보호적인 작용이 아닌 autophagic cell death이며, 길경 추출물이 대장암 세포주에서 암세포의 사멸을 유도하는 효과적인 대안이 될 수 있음을 알 수 있었다.

  • Hepatocellular carcinoma (HCC) has been one of the most fatal malignant tumors worldwide and its associated morbidity and mortality remain of significant concern. Based on in-depth reviews of serological diagnosis of HCC, in addition to AFP, there are other biomarkers: Lens culinaris agglutinin-reactive AFP (AFP-L3), descarboxyprothrombin (DCP), tyrosine kinase with Ig and eprdermal growth factor (EGF) homology domains 2 (TIE2)-espressing monocytes (TEMs), glypican-3 (GPC3), Golgi protein 73 (GP73), interleukin-6 (IL-6), and squamous cell carcinoma antigen (SCCA) have been proposed as biomarkers for the early detection of HCC. The diagnosis of HCC is primarily based on noninvasive standard imaging methods, such as ultrasound (US), dynamic multiphasic multidetector-row CT (MDCT) and magnetic resonance imaging (MRI). Some experts advocate gadolinium diethyl-enetriamine pentaacetic acid (Gd-EOB-DTPA) MRI and contrast-enhanced US as the promising imaging madalities of choice. With regard to recent advancements in tissue markers, many cuting-edge technologies using genome-wide DNA microarrays, qRT-PCR, and proteomic and inmunostaining studies have been implemented in an attempt to identify markers for early diagnosis of HCC. Only less than half of HCC patients at initial diagnosis are at an early stage treatable with curative options: local ablation, surgical resection, or liver transplant. Transarterial chemoembolization (TACE) is considered the standard of care with palliation for intermediate stage HCC. Recent innovative procedures using drug-eluting-beads and radioembolization using Yttrium-90 may exhibit beneficial effects in HCC treatment. During the past few years, several molecular targeted agents have been evaluated in clinical trials in advanced HCC. Sorafenib is currently the only approved systemic treatment for HCC. It has been approved for the therapy of asymptomatic HCC patients with well-preserved liver function who are not candidates for potentially curative treatments, such as surgical resection or liver transplantation. In the USA, Europe and particularly Japan, hepatitis C virus (HCV) related HCC accounts for most liver cancer, as compared with Asia-Pacific regions, where hepatitis B virus (HBV) may play a more important role in HCC development. HBV vaccination, while a vaccine is not yet available against HCV, has been recognized as a best primary prevention method for HBV-related HCC, although in patients already infected with HBV or HCV, secondary prevention with antiviral therapy is still a reasonable strategy. In addition to HBV and HCV, attention should be paid to other relevant HCC risk factors, including nonalcoholic fatty liver disease due to obesity and diabetes, heavy alcohol consumption, and prolonged aflatoxin exposure. Interestingly, coffee and vitamin K2 have been proven to provide protective effects against HCC. Regarding tertiary prevention of HCC recurrence after surgical resection, addition of antiviral treatment has proven to be a rational strategy.

  • During the past 10 years, concern for community people's health has increased together with the changes. Public health policies and studies for community people's health, however, have influenced those in childmaternal health care to want more general coverage and studies of health and wellness. Particularly, the study of community people's health in the extent an island area is almost rare as that personal and the material benefits in this area are lacking of community people's work is large, and the basic elements of living, such as diet and elimination, are irregular due to the schedule of the tide. Thus, there are many potential health problems. In this regard, the study attempted to understand the health problems of island community people and to provide a basis for developing health promotion and health education programs. In collecting data for the study, face to face interviews were made through a structured questionnaire from October 1 to December 30, 1996. Collected data were analyzed with the SAS statistics program, descriptive statistics, t-test and ANOVA. Subjects' health status was examined by classifying into such categories as their health perception, complaints of health problem, related lifestyle, psychosocial health staus, the result of examination is as follows; 1. For subjects' health perception, 26.9% of the subject answered not sick, but not so healthy'; 30.9% thought they were healthy, while 22.9% answered that they were not healthy. 2. For the health problem complaints many complained of pains in their muscles and skeletal system, especially knee joint pain. Women's health problems related with breast and the reproductive system included 52.3% of cases doing breast self examination, while 56.55% received the cervical cancer screening test. In men's health problems, 44.2% of subjects answered that they have moderate to severe BPH(Benign Prostatic Hypertrophy) symptom. 3. There were statistically a significant difference in the degree of physical health according to marital status(p=0.0028), occupation(p=0.0442), income(p=0.0357). 4. For stress status, 17.2% was to need the intervention, 50.2% was to need observation. 5. The mean score of self-esteem was 27.7 showing a relatively high score. 6. For the rate of smoking, 37.7% used to smoke, while 28% used to take alcohol. 7. The rate of substance abuse was 45.9% of subjects. 8. Most of subjects' health behaviors included most of the acupuncture (52%). 9. The rate of subjects receiving comprehensive medical testing was 34.36% while 34.78% did after care managing behavior. 10. For the obesity grade, 53% is normal weight, low-weight 32.8%, obesity 33%. 11. For nutrition status, 78.7% illy balanced to need intervention of nutritional education. 12. For 78.7% of subjects, muscle strength and 40.7% of stretching were not good enough to need health education on physical exercises.

  • Microorganism residing in the gut has been known to have important roles in the animal body. Microbes and host microenvironment are highly related with host's health including energy metabolism and immune system. Moreover, it reported that gut microbiome is correlated with diseases like obesity in human and dogs. There have been many studies to identify and characterize microbes and their genes in human body. However, there was little information of microbiome in companion animals. Here, we investigated microbiota communities in feaces from twenty - four Beagles (aged 2 years old) and analyzed the taxonomy profile using metagenomics to study the difference among gut microbiome based on body condition score (BCS). gDNA was isolated from feaces, sequenced and clustered. Taxonomy profiling was performed based on the NCBI database. BCS was evaluated once a week according to the description provided by World Small Animal Veterinary Association. Firmicutes phylum was the most abundant followed by Bacteroidetes, Fusobacteria, Proteobacteria and Actinobacteria. That main microbiota in gut were differently distributed based on the BCS. Fusobacteria has been known to be associated with colon cancer in human. Interestingly, Fusobacteria was in the third level from the top in healthy dog's gut microbiome. In addition, Fusobacteria was especially higher in overweight dogs which had 6 scales of BCS. Species Fusobacterium perfoetens was also more abundant when dogs were in BCS 6. It implied that F. perfoetens would be positively related with overweight in dogs. These finding would contribute to further studies of gut microbiome and their functions to improve dog's diets and health condition.

  • Objectives: Being overweight or obese is central to metabolic syndrome, and these characteristics constitute dominant risk factors for chronic diseases. Although behavioral factors, including eating habits and sedentary lifestyles, are considered to be determinants of obesity, the specific childhood factors that contribute to this condition have not been clearly defined. Methods: The subjects consisted of 261 children aged 7- 9 years who were recruited from an elementary school during October 2003. Information was obtained from their parents using a questionnaire focused on eating behaviors and lifestyle factors, additional data were also collected via anthropometric measurements and biochemical examinations, including blood tests. Results: A total of 48 (18.4%) of the 261 children were overweight, and 34 (70.8%) had at least one other component of metabolic syndrome. Eating behaviors emerged as significant lifestyle-related risk factors for being overweight or obese. Those who engaged in overeating more than twice per week had three times the risk of being overweight (odds ratio [OR], 3.10, 95% confidence interval [CI], 1.39 to 6.92), and those who ate rapidly had three times the risk of being overweight (OR, 3.28; 95% CI, 1.68 to 6.41). Those who had fewer family meals (fewer than 2?3/month) had a nine times higher risk of being overweight than those who had family meals more frequently (at least 1/day) (OR, 9.51; 95% CI, 1.21 to 74.82). Conclusions: This study showed that being overweight or obese during preadolescence is associated with a higher risk of metabolic syndrome and is related to unhealthy eating behaviors. Thus, weight-control strategies and healthy eating behaviors should be developed early in life to reduce the risk for metabolic syndrome.

  • Objectives: Peroxynitrite ($ONOO^-$), superoxide anion radical (${\cdot}{O_2}^-$ and nitric oxide (NO) are cytotoxic because they can oxidize several cellular components such as proteins, lipids and DNA. They have been implicated in the aging processes, and age-related diseases such as Alzheimer's disease, rheumatoid arthritis, cancer, diabetes, obesity and atherosclerosis. The aim of this study was to investigate the $ONOO^-$, NO, ${\cdot}{O_2}^-$ scavenging and NF-${\kappa}B$ related anti-inflammatory activities of Sotosaja-hwan in ob/ob mice. Methods: Mice were grouped and treated for 5 weeks as follows. Both the normal lean (C57/BL6J black mice) and control obese (ob/ob mice) groups have received standard chow. The experimental groups were fed with a diet of chow supplemented with 30 and 90 mg Sotosaja-hwan per 1 kg of body weight for 14 days. For this study, the fluorescent probes, namely 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), 4,5-diaminofluorescein (DAF-2) and dihydrorhodamine 123 (DHR 123) were used. Western blotting was performed using anti-phospho-$I{\kappa}B$-${\alpha}$, anti-IKK-${\alpha}$, anti-NF-${\kappa}B$ (p50, p65), anti-COX-2, anti-iNOS, anti-YCAM-1 and anti-MMP-9 antibodies, respectively. Results: Sotosaja-hwan inhibited the generation of $ONOO^-$, NO and ${\cdot}{O_2}^-$ in the lipopolysaccharide (LPS)-treated mouse kidney postmitochondrial fraction in vitro. The generation of $ONOO^-$, NO, ${\cdot}{O_2}^-$ and PGE2 were inhibited in the Sotosaja-hwan-administered ob/ob mice groups. The GSH/GSSG ratio was decreased in the ob/ob mice, whereas the ratio was improved in the Sotosaja-hwan-administered groups. Sotosaja-hwan inhibited the protein expression levels of phospho-$I{\kappa}B$-${\alpha}$, IKK-${\alpha}$, NF-${\kappa}B$ (p50, p65), COX-2, iNOS, YCAM-1 and MMP-9 genes. Conclusions: These results suggest that Sotosaja-hwan is an effective $ONOO^-$, ${\cdot}{O_2}^-$ and NO scavenger and has NF-kB related anti-inflammatory activity in ob/ob mice. Therefore, Sotosaja-hwan might be a potential therapeutic drug against the inflammation process and inflammation-related diseases.

  • 규칙적인 운동은 혈압을 낮춰주고 체중조절과 스트레스 해소에도 도움을 주기 때문에 협심증이나 심근경색과 같은 관상동맥질환을 예방하는데 효과가 있다. 동맥경화증을 촉진시키는 위험인자로는 고혈압, 고지혈증, 당뇨병, 비만, 지나친 흡연, 운동부족 등을 들 수 있으며, 동맥경화의 진행은 어려서부터 시작되어 연령의 증가와 어불어심해진다. 특히, 여자보다 남자에게서 더 심하다. 동맥경화증 위험인자가 있는 사람의 경우 식습관과 생활양식, 그리고 운동처방으로 동맥경화성 질환을 예방하는 것이 중요하다. 식이섬유는 체내에서 소화관의 운동을 촉진하여 장관내 체류기간을 단축시키며 콜레스테롤의 흡수를 저해하여 비만, 고지혈증, 동맥경화 및 대장암 등을 예방할 수 있다. 각종 채소류와 해조류는 불포화지방산이 다량으로 함유된 식품으로서 장내에서 콜레스테롤 흡수를 방해하는 역할을 한다. 또한 식물성 기름에 함유되어 있는 필수지방산과 불포화지방은 콜레스테롤의 대사를 촉진하는 반면 흡수를 방해하며, 과일류에는 수용성 식물섬유인 팩틴이 함유되어 있어 체내의 콜레스테롤치를 떨어뜨린다. 콜레스테롤 및 포화지방산이 적고 불포화지방산이 많은 음식을 섭취하도록 하며 식이요법만으로도 콜레스테롤치를 10~15% 감소시킬 수 있다. 운동과 식이를 병행하여 운동을 지속적으로 장기간 할 때 효과가 매우 크다. 운동은 유산소성 운동으로서 운동강도는 HRmax의 60~80$\%$ $Vo_2$ max 50~70$\%$), 운동시간은 15~60분/day, 운동빈도는 3-6회/week가 바람직하다. 특히 심한 고혈압의 경우에는 환자의 상태에 따른 운동처방의 배려가 있어야 되며, 의사와 상의하여 전문적인 처방이 필요하다. 확인되었다.H, ENO1, ADH1 promoter 순으로 나타났지만, 초기 포도당 농도가 높을 때나 에탄을 생산이 심각한 유가식 배양에서는 ENO1 promoter가 inulinase의 구성적 발현ㆍ생산에 더 적합할 것으로 사료된다.라서 체중조절을 위해서는 식이제한 보다는 자유로운 식이 섭취의 방법을 통해 더 많은 운동기간을 가지고 운동을 한다면 체중조절은 물론 근육 대사를 원활히 하여 건강한 생활을 할 수 있으리라 기대한다.공정에서 매우 효과적으로 이용될 수 있을 것으로 판단된다.게 기여하리라고 전망된다.
