The aim of the present study was to investigate the effect of single nucleotide polymorphisms in the major histocompatibility complex (MHC) class II gene on resistance to Newcastle disease virus and body weight of the Thai indigenous chicken, Leung Hang Khao (Gallus gallus domesticus). Blood samples were collected for single nucleotide polymorphism analysis from 485 chickens. Polymerase chain reaction sequencing was used to classify single nucleotide polymorphisms of class II MHC. Body weights were measured at the ages of 3, 4, 5, and 7 months. Titres of Newcastle disease virus at 2 weeks to 7 months were determined and the correlation between body weight and titre was analysed. The association between single nucleotide polymorphisms and body weight and titre were analysed by a generalized linear model. Seven single nucleotide polymorphisms were identified: C125T, A126T, C209G, C242T, A243T, C244T, and A254T. Significant correlations between log titre and body weight were found at 2 and 4 weeks. Associations between single nucleotide polymorphisms and titre were found for C209G and A254T, and between all single nucleotide polymorphisms (except A243T) and body weight. The results showed that class II MHC is associated with both titre of Newcastle disease virus and body weight in Leung Hang Khao chickens. This is of concern because improved growth traits are the main goal of breeding selection. Moreover, the results suggested that MHC has a pleiotropic effect on the titre and growth performance. This mechanism should be investigated in a future study.

Ulcerative colitis (UC), chronic inflammatory bowel disease, is characterized by severe inflammation in the colon. Tea is one of the most popular beverages consumed worldwide. Pu-erh tea, a unique Chinese tea produced by microbial activities, possesses a broad range of health-promoting effects, including anti-aging, anti-Alzheimer's disease, antioxidation and anti-obesity. However, the inhibitory effect of Pu-erh tea on intestinal inflammation and the underlying mechanism remain unclear. The present study was designed to evaluate the regulatory effect of Pu-erh tea extract (PTE) on dextran sulfate sodium (DSS)-induced colitis clinical signs by analyzing the weight loss and colon length in mice. The inhibitory effects of PTE on inflammatory mediators, such as interleukin (IL)-6 and tumor necrosis factor (TNF)-α, and the activation of nuclear factor-κB (NF-κB) were also determined in DSS-treated colitis tissue. We observed that PTE treatment significantly inhibited the DSS-induced clinical symptoms of weight loss, decrease,in colon length, and colon tissue damage in mice. Moreover, PTE attenuated the DSS-induced levels of IL-6 and TNF-α in colon tissue. We also demonstrated the anti-inflammatory mechanism of PTE by suppressing the activation of NF-κB in DSS-treated colon tissues. Collectively, the findings provide experimental evidence that PTE may be effective in preventing and treatment of intestinal inflammatory disorders, including UC.

This study investigated a mechanism of naming a disease, as examining how obesity attain a status of disease. WHO(World Health Organization) warned 'The obesity is definitely a disease to need medical treatment' in 1996 and 1997. However, before then, obesity was classified as unusual or nonstandard body status but it was not categorized as a disease. In order to examine a mechanism how obesity attain the status of disease, this study examined the historical process of construction to obesity in discourse of disease and ontological reality of pathological epidemiological to obesity. As a result of this research, it was found that the medical community manipulated BMI(Body Mass Index) and deliberately narrowed the range of person's normal weight, and institutionalized sizism. Especially, it was found that as the medical community associated the body state of obesity with high blood pressure, diabetes, and etc that causes burden of medical expenses to patients, that was fatphobia. And it tried to from a medical control mechanism to assign obesity to an independent status of a disease. Based on this examination, this study found an entailment: the noninfectious disease such as obesity attains the status of disease not because of the pathologic reason but because of cultural or socio-economical reason which han nothing to do with any medical source.

The prevalence of childhood obesity is increasing worldwide at an alarming rate. While obesity is known to increase a variety of cardiovascular and metabolic diseases, it also acts as a risk factor for the development and progression of chronic kidney disease (CKD). During childhood and adolescence, severe obesity is associated with an increased prevalence and incidence of the early stages of kidney disease. Importantly, children born to obese mothers are also at increased risk of developing obesity and CKD later in life. The potential mechanisms underlying the association between obesity and CKD include hemodynamic factors, metabolic effects, and lipid nephrotoxicity. Weight reduction via increased physical activity, caloric restriction, treatment with angiotensin-converting enzyme inhibitors, and judicious bariatric surgery can be used to control obesity and obesity-related kidney disease. Preventive strategies to halt the obesity epidemic in the healthcare community are needed to reduce the widespread deleterious consequences of obesity including CKD development and progression.

Ulcerative colitis (UC) is an inflammatory bowel disease and a chronic gastrointestinal disorder. Rubi Fructus (RF), the fruit of Rubus coreanus Miquel, is known to exert several pharmacological effects including anti-oxidative, anti-obesity and anti-inflammatory properties. However, the improving effect and mechanism of RF on intestinal inflammation is not been fully understood. The purpose of this study was to investigate the regulatory effect of RF on dextran sulfate sodium (DSS)-induced colitis in mice. We evaluated the effects of RF on DSS-induced clinical signs by analyzing weight loss and colon length. The inhibitory effects of RF on inflammatory mediators such as prostaglandin E₂ (PGE₂), cyclooxygenase (COX)-2, as well as the activation of nuclear factor-κB (NF-κB), were determined in colitis tissue. Our data indicated that mice treated with DSS showed clinical symptoms of colitis, including weight loss, colon length decrease and diarrhea. However, we observed that RF treatment significantly improved these clinical symptoms of weight loss, colon length decrease and diarrhea induced by DSS. RF inhibited the enhanced levels of COX-2 and PGE₂ caused by DSS. We also showed that the anti-inflammatory mechanism of RF by suppressing the activation of NF-kB in DSS-treated colon tissues. Collectively, the findings of this study indicate the prospect of developing new drugs from RF for UC treatment.

Depressive disorder is a very common disease, clinical manifestations vary, and the mechanism is not clear. Therefore, a pharmacotherapy is very important to achieve sufficient therapeutic effect, but the choice of drug is not easy due to the occurrence of side effects of treatment and confusion with clinical features. It is easy to overlook the side effects of weight gain with antidepressants compared with antipsychotics, but they are frequently observed in clinical settings. The first-generation antidepressants have higher weight gains than selective serotonin reuptake inhibitors. Serotonin norepinephrine reuptake inhibitors are observed to have less weight gain, and dopamine norepinephrine reuptake inhibitors have weight loss effect due to decreased appetite. Mirtazapine, an atypical antidepressant, has a strong histamine H1 blockade, and gains weight gain from short-term use. The effects of desvenlafaxine, vortioxetine, and agomelatin on weight, which have recently been increasing in use, have not been largely identified. For better compliance, studies on weight gain due to the use of antidepressants are needed.

Objectives : Crohn's disease is a severe chronic inflammation that is treated mainly by immunosuppression, which often has serious side effects. There is need to develop new therapeutic methods or drugs that have few side effects in order to treat this disease. Acupuncture with Moxi-tar at Cheonchu (ST25) has anti-inflammatory properties, but the mechanism of its anti-inflammatory actions is unclear. We investigated the protective effects and speculated the mechanisms of acupuncture with Moxi-tar at ST25 on trinitrobenzene sulfonic acid (TNBS) induced colitis in mice which is a well known Crohn's disease animal model. Methods : 5 % TNBS was treated at day 1 and day 7 into rectum of mice. To investigate therapeutic effects of acupuncture with Moxi-tar at ST25, acupuncture was carried out on day 3, and day 6. For the data analysis, we observed macroscopic and microscopic findings of the colon. Weight and width of the colon, degree of damage, changes of body weight, and myeloperoxygenase (MPO) activity were checked. For analysing protein expression, we carried out immunohistochemical staining and Western blot. For analysing mRNA expression, RT-PCR was carried out. Results : TNBS induced damages on the colon of mice, while acupuncture of Moxi-tar at ST25 suppressed TNBS mediated damages similar to those on the colons of mice in the control (not treated with TNBS) group. The average body weight of TNBS treated mice (77.4%) was decreased compared with that of the control mice (105%), and acupuncture with Moxi-tar at ST25 suppressed the loss of body weight caused by TNBS (from 77.4% to 95.3%). TNBS induced infiltration of immune cells in all layers of the colon while acupuncture with Moxi-tar at ST25 suppressed infiltration of immune cells caused by TNBS. Furthermore, acupunctured with Moxi-tar at ST25 suppressed macro-, micro- colonic damages caused by TNBS. Acupunctured with Moxi-tar at ST25 dramatically improved the clinical and histopathological symptoms such as the increase in weight of the distal colon and the MPO activity in TNBS-induced colitis. Acupuncture with Moxi-tar at ST25 down-regulated the nuclear transcription factor kappa B ($NF-{\kappa}B$) activity and suppressed tumor necrosis factor-a (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-1${\beta}$), and intracellular adhesion molecule-1 (ICAM-1) expressions caused by TNBS. Conclusions : Acupuncture with Moxi-tar at ST25 helps recovery from the TNBS-induced colonic damage by down-regulation of $NF-{\kappa}B$ activity and suppressing of TNF-${\alpha}$, IL-1${\beta}$, and ICAM-1 expressions. This may be an important method for the treatment of Crohn's disease.

Since Barker found associations between low birth weight and several chronic diseases later in life, the hypothesis of fetal origins of adult disease (aka, Barker Hypothesis) and epigenetics have been emerging as a new paradigm for geneenvironment interaction of chronic disease. Epigenetics is the study of heritable changes in gene silencing that occur without any change in DNA sequence. Gene expression can be regulated by several epigenetic mechanisms, including DNA methylation and histone modifications, which may be associated with chronic conditions, such as cancers, cardiovascular disease, and type-2 diabetes. One carbon metabolism which involves the transfer of a methyl group catalyzed by DNA methyltransferase is an important mechanism by which DNA methylation occurs in promoter regions and/or repetitive elements of the genome. Environmental factors may induce epigenetic modification through production of reactive oxygen species, alteration of methyltransferase activity, and/or interference with methyl donors. In this review, we introduce recent studies of epigenetic modification and environmental factors, such as heavy metals, environmental hormones, air pollution, diet and psychosocial stress. We also discuss epigenetic perspectives of early life environmental exposure and late life disease occurrence.

The most common cause of blindness is cataract. The possible causes, radiation, sugar, drugs, trauma, nutrition, congenital, secondary to eye disease etc. Generally, the opacification of the lens are the result fa oxidation of the lens fibers. The basis for lens transparency is the structural integrity of lens fibers. Opacities were occur if there is a significant amount of high molecular weight protein aggregates. If Ca ions combined with lens ${\alpha}$-crystallin proteins, the lens fibers were aggregated by high molecular weight proteins and the lens were opacified. If Ca ions detached from lens ${\alpha}$-crystallin proteins, the lens fibers were aggregated by low molecular weight proteins and the lens were re-cleared. We need to find out the variety of factors can initiated the process of age-related cataract. And to understanding the mechanism how the various kind, of diabetic cataracts occur.
