This book was released on 2003 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food intake is supposed to be controlled, to a certain extent, by metabolic factors including glycogen metabolism in the liver. Glutamine and dihydroxyacetone are substances known to increase hepatic glycogenesis. In obese individuals, macronutrient composition of the diet has little effect on the magnitude of weight loss over the short term unless nutrient composition affects caloric intake. Recent weight loss studies have shown the effectiveness of high protein diets in the obese but the complete physiological mechanism behind the success of these diets is still somewhat vague. The present study was designed to investigate the acute effect of different high protein diets, with or without glutamine and dihydroxyacetone, on hepatic glycogen synthesis and food intake of normal Sprague-Dawley rats. Thirty-two male Sprague-Dawley rats were randomly divided into five groups. Groups were divided according to diet (C: control, HPLF: high protein low fat, HPLF+GDHA: high protein low fat supplemented with glutamine and dihydroxyacetone, HPHF: high protein high fat, HPHF+GDHA: high protein high fat supplemented with glutamine and dihydroxyacetone). Rats were ad lib fed the appropriate diet for 3 days. On the last day, they were fasted overnight, tube fed the following morning with 1.25g their respective diets, injected i.p. with 3mCi of 3H20 and sacrificed one hour later. Plasma and tissue samples were collected. Results showed a significant decrease in food intake and weight gain in HPHF+GDHA group. Postprandial plasma insulin level was also the lowest in the HPHF+GDHA group. Postprandial hepatic glycogen synthesis was higher in GDHA supplemented diets when compared to the unsupplemented high protein diets. In conclusion, high protein, high fat diet supplemented with glutamine and dihydroxyacetone resulted in a decrease in weight gain and food intake possible due to diarrhea. This was associated with an increase in postprandial glycogen synthesis.

This book was released on 2004 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The therapeutic use of glucocorticoids is associated with weight gain and may pl ay an important role in the initiation of obesity, an effect which is undesirabl e and even detrimental. Studies have shown that glucocorticoids increase the dep osition of glycogen in the liver, but it is not known whether this is caused by a decrease in breakdown and /or an increase in synthesis. The present experiment was designed to study the effect of a high pro tein-high fat diet versus a high protein-low fat diet on in vivo postprandial he patic glycogen synthesis of rats taking glucocorticoids. Thirty nine six-week ol d male Sprague-Dawley rats were randomly divided into five groups: C, control; H P-LF, high protein-low fat; HP-HF+G, high protein high fat with prednisolone; HP -HF, high protein-high fat; HP-HF+G, high protein-high fat prednisolone. Pellets containing 0.25mg of prednisolone each (60-day release) were implanted subcutan eously. The rats were then maintained on their respective diets for 6 weeks, and then fasted overnight. On the day of the experiment, each rat was given 1.25g o f its respective diet by gavage, immediately injected i.p. with 4mCi of H2O, sac rificed one hour later. Blood, liver and fat were taken for analysis. Results showed the plasma glucose concentrations of rats maintained on HP-LF diets were higher than those maintained on HP-HF diets and this was not a ffected by the presence of glucocorticoids. Glycogen content (mg/g liver) was si milar among all groups. Hepatic glycogen synthesis was higher in rats maintained on HP-LF diets compared with those on HP-HF diets and was not substantially aff ected by the presence of glucocorticoids. The percentage of glycogen synthesis v ia pyruvate (indirect pathway) was also higher in rats maintained on the low fat diets compared with those on high fat diets; glucocorticoids did not seem to pl ay a role in this case either. Under high protein conditions, hepatic glycogen synthesis as well as i ts synthesis via pyruvate was increased in the LF groups, and this was not alter ed by prednisolone. Therefore, dietary manipulation seems to be the main determi nant of glycogen metabolism, an effect which does not seem to be overridden by t he presence of glucocorticoids.

Download or read book Cooperation of Liver Cells in Health and Disease written by Z. Kmiec and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is only during the last decade that the functions of sinusoidal endothelial cells, Kupffer cells, hepatic stellate cells, pit cells and other intrahepatic lymphocytes have been better understood. The development of methods for isolation and co-culturing various types of liver cells has established that they communicate and cooperate via secretion of various intercellular mediators. This monograph summarizes multiple data that suggest the important role of cellular cross-talk for the functions of both normal and diseased liver. Special features of the book include concise presentation of the majority of detailed data in 19 tables. Original schemes allow for the clear illustration of complicated intercellular relationships. This is the first ever presentation of the newly emerging field of liver biology, which is important for hepatic function in health and disease and opens new avenues for therapeutic interventions.

This book was released on 1999-10-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.
