A metabolic study was conducted with four ruminally-cannulated lactating goats (Saanen, 29 weeks lactation, 65${\pm}$5 kg) in a 4${\times}$4 Latin square design with 4 dietary treatments. The goats were fed a basal mixed diet consisting of 80% concentrate and 20% chopped rye grass hay (DM basis, CON). The goats were also fed the CON diet supplemented with soybean oil at a 5% level of the concentrate (SO), the SO diet supplemented with 0.5% of sodium bicarbonate (SO-B) or the SO-B diet supplemented with 30 ppm monensin (SO-BM). The goats were housed in individual pen and the study was conducted for 8 weeks. An increased molar proportion of propionate (C3) was observed at 1 h (p<0.003) and 6 h (p<0.029) post-feeding from all the supplemented diets. Calculated methane emission was markedly decreased prior to morning feeding (p<0.01), and at 1 h (p<0.05) and 6 h post-feeding (p<0.05) in goats fed the supplemented diets. All the supplements increased (p<0.0001) cis9, trans11-CLA content in rumen fluid. Concentrations of both cis9, trans11-CLA (p<0.0001) and trans10, cis12-CLA (p<0.026) were also increased in the milk fat of lactating goats fed the supplemented diets. The SO-B and SO-BM diets further increased CLA content in goat milk compared to the SO diet. All supplements increased unsaturated (UFA, p<0.002), monounsaturated (MUFA, p<0.002) and polyunsaturated fatty acids (p<0.014) and reduced SFA to UFA ratio (p<0.023). The concentration of MUFA was even greater (p<0.002) for SO-BM than for the SO-B diet. In conclusion, feeding soybean oil (5% of concentrate) to lactating goats was a useful way to improve milk fat and to improve fatty acid profile in the milk by increasing potentially healthy fatty acids such as CLA. Supplementation of sodium bicarbonate or sodium bicarbonate with monensin to the soybean oil-based diet increased CLA content further in goat milk. Supplementation of soybean oil may be an effective method to reduce methane emission in lactating goats.

Objectives : Obesity is a chronic metabolic disease caused by disorder of energy balance and lipid metabolism. This study was conducted by histopathology and histomorphometry to investigate the anti-obesity effects of mixed water extract of Plantaginis Semen & Poria (CJB) on liver, epididymal fat pads and pancreas zymogen granules in obese rats induced with high fat diet. Method : Male Sprague-Dawley rats to be divided four groups were fed into four different treatments: normal (NOR) diet, high-fat (HF) diet, HF diet+CJB (100 mg/kg and 300 mg/kg, P.O.) for 8 weeks. The weekly body weights were measured in four experimental groups, respectively. Also histopathological and histomorphometrical changes of liver, epididymal fat pads and pancreas zymogen granules were observed in normal control and obese rats, respectively. Results : Adminstration of CJB significantly reduced body weights compared to those of HF group for experimental period. After 8 weeks, liver weights in the CJB groups were lower than those of HF group. In addition, HF diet related steatohepatitis, adipocyte hypertrophy, exocrine disturbances (decreases of pancreatic zymogen granules) were also dose-dependently inhibited by treatment of test material, CJB 100 and CJB 300 as compared with HF group, respectively. Conclusion : Based on the results, it is considered that CJB will be showed hepatoprotective and anti-obese effects, may be directly and/or indirectly mediated by pancreatic zymogen granules because they dose-dependently inhibited steatohepatitis, hypertrophy of adipocytes and decreases of pancreatic zymogen granules induced by HF diet supply, respectively.

The hypothalamus is a crucial organ for the maintenance of appropriate body fat storage. Neurons in the hypothalamic arcuate nucleus (ARH) detect energy shortage or surplus via the circulating concentrations of metabolic hormones and nutrients, and then coordinate energy intake and expenditure to maintain energy homeostasis. Malfunction or loss of hypothalamic ARH neurons results in obesity. Accumulated evidence suggests that hypothalamic inflammation is a key pathological mechanism that links chronic overconsumption of a high-fat diet (HFD) with the development of obesity and related metabolic complications. Interestingly, overnutrition-induced hypothalamic inflammation occurs specifically in the ARH, where microglia initiate an inflammatory response by releasing proinflammatory cytokines and chemokines in response to excessive fatty acid flux. Upon more prolonged HFD consumption, astrocytes and perivascular macrophages become involved and sustain hypothalamic inflammation. ARH neurons are victims of hypothalamic inflammation, but they may actively participate in hypothalamic inflammation by sending quiescence or stress signals to surrounding glia. In this mini-review, we describe the current state of knowledge regarding the contributions of neurons and glia, and their interactions, to HFD-induced hypothalamic inflammation.

Chemoprevention refers to the use of non-toxic chemical agents to prevent the neoplastic development by inhibiting, delaying, or reversing a multi-stage carcinogenesis. The primary goal of chemoprevention research is to identify or produce effective agents and strategies for clinical trials for applications to normal or high risk human populations. A large number of compounds have been tested for their possible chemopreventive activities, and it is of interest to note that many of them are naturally occurring substances. Thus, a variety of plant and vegetable constituents, particularly those included in our daily diet, have been found to possess substantial protective properties against experimental carcinogenesis. These substances, collectively known as dietary phytochemicals, exert their chemopreventive effects by influencing specific step(s) of multi-stage carcinogenesis: some inhibit metabolic activation or enhance detoxification of carcinogens, others interfere with covalent interactions between ultimate eloctrophilic carcinogens and the target cell DNA and still others may exert anti-promoting or anti-progressing effects. Mechanism-based interventions by use of safe dietary phytochemicals may provide one of the most practical and promising cancer chemopreventive strategies.

In the present highly changing era, every dimension from Technology to Education, Environment to Sanitation and from Agriculture to our Food basket is getting changed. Our experiences say that the most affected ethnic group from this rapidly changing pattern of our food intake, lifestyle are our adolescent. This is also a fact that our adolescent passes their 2/3 of time of a day in their schools. In this regard our school system needs to formulate their comprehensive approach to Health for our adolescents. On other hand Ayurveda, the ancient Indian system of Medicine had expressed views on a concept of Holistic Health thousand years ago. This research article is an attempt of borrowing this valuable concept from Ayurveda and suggesting to introduce them into our comprehensive school health programme such as concept of wellness, quality of life, Holistic Health and measures related to diet and lifestyle for preservation, promotion of health and prevention of disorders etc. This manuscript also evaluates the existing approaches of school health programmes towards current scenario. Now a day's our food habits, dietary intake and the life style are not at the level of satisfactory condition this lead to early onset of metabolic chronic disorder especially in our adolescents because on the basis of age-immunity relationship they are easily targeted. The chronic metabolic disorders results into overweight, obesity, anxiety, mental trauma, distress, over- fatigued, incapable for physical work, getting tired soon. This article provides a space to rethink and reformulate our school health programmes in light of our ancient tradition of medicine.

Probiotics have been known to reduce high-fat diet (HFD)-induced metabolic diseases, such as obesity, insulin resistance, and type 2 diabetes. We recently observed that Lactobacillus acidophilus NS1 (LNS1), distinctly suppresses increase of blood glucose levels and insulin resistance in HFD-fed mice. In the present study, we demonstrated that oral administration of LNS1 with HFD feeding to mice significantly reduces hepatic expression of phosphoenolpyruvate carboxykinase (PEPCK), a key enzyme in gluconeogenesis which is highly increased by HFD feeding. This suppressive effect of LNS1 on hepatic expression of PEPCK was further confirmed in HepG2 cells by treatment of LNS1 conditioned media (LNS1-CM). LNS1-CM strongly and specifically inhibited $HNF4{\alpha}-induced$ PEPCK promoter activity in HepG2 cells without change of $HNF4{\alpha}$ mRNA levels. Together, these data demonstrate that LNS1 suppresses PEPCK expression in the liver by regulating $HNF4{\alpha}$ transcriptional activity, implicating its role as a preventive or therapeutic approach for metabolic diseases.

1. The obesity is the aggregation of symptoms accompanied with the metabolic disorder and the increase of fatty layer accumulation by the enlargement or increase of fatty cells, which is the condition that has 20% overweight than the standard. 2. The final metabolic of fat depends on the defensive energy. The shape of fatty layer is changed by the point where is the defensive energy is replenish or not. So Goin, Bein and Yuckin is made a discriminated and there is different between Besudaeso and Herlgidaso. 3. In case of liver overacting spleen by seven emotions, we can use reinforcing the spleen and don't use depressing energy. 4. Damp, weakness of Qi(氣), weakness of spleen came from seven emotion, and social stress can occur obesity. Obesity is reason of C.V.A, dizziness, dementia, schizophrenia, etc. 5. The obesity which can occurs various adult diseases came from eating disorder and various stresses at the standpoint of western medical. This is cured by diet, kinesiatrics, operation, pharmacotherapy, etc.

Purpose: We retrospectively investigated individuals who hadbeen identified by neonatal screening as potential galactosemia patients to determine the etiology of galactosemia. Methods: One hundred fifty-three patients referred to Korea Genetics Research Center due to high galactose level detected by neonatal screening test between February 2005 and May 2013 were examined. Galactose and galactose-1-phosphate levels were measured by using a fluoro metric microplate reader. Lactose free diet was initiated immediately after confirmed by urine Clinitest. If reducing sugar was negative, we employed abdominal sonogram and echocardiogram to check for possible porto-systemic shunt. Results: Fifteen patients were diagnosed with galactosemia. One patient had galactokinase (GALK) deficiency; four had UDP galactose-4-epimerase (GALE) deficiency; two had citrin deficiency; and four had porto-systemic shunt. Two had unknown causes of galactosemia. Conclusion: In addition to genetic defects of GALT, GALK and GALE, citrin deficiency or porto-systemic shunt could also cause galactosemia. It is crucial to carry out differential diagnosis to determine the cause of galactosemia.
