This article dissusses the biological function of the glutamine in exercise, the influence of exercise on glutamine level, the effect of the glutamine in immune system, put forwards the relationship between exerise and glutamine metabolism.
Objective: The aim of this study was to examine the effect of total parenteral nutrition (TPN) on the glutamine metabolism of the tissues in rats. Methods: The concentration of glutamine was determined by high performance liquid chromatography (HPLC). Results: The results showed that TPN induced marked reduction of glutamine concentration in tissues and blood ( P <0.05 or P <0.01).
Aim Since the absence of glutamine(GLN)has an adverse effect on the structure and function of the small intestine, this study was designed to investigate the expression of the two main genes of glutamine metabolism, glutaminase(GLNase) and glutamine synthetase(GS),in the intestinal mucose after induction of acute noecrotizing pancreatitis(ANP) without or with growth hormone (GH) treatment in rats.
Although the final result of ammoniainhibition of nitrogenase activity in phototro-phic bacteria is now fairly well understood,there is very little information about theevents leading to the modification of the ironprotein. The aim of this paper was to learnmore about the factors that influence the ironprotein modification system. Nitrogenase activity in Rhodobacter spha-eroides strain 601 was subjected to a rapidswitch-off in response to exogenous ammonia(Fig. 1). However, the inhibition caused byammonia w...
Objective: The aim of this study was to examine the effect of total parenteral nutrition (TPN) on the glutamine metabolism of the tissues in rats. Methods: The concentration of glutamine was determined by high performance liquid chromatography (HPLC). Results: The results showed that TPN induced marked reduction of glutamine concentration in tissues and blood ( P <0.05 or P <0.01). Prolonged TPN leads to further reduction ( P <0.01). The TPN solution enrinched with glutami...
AIM: Ammonia(NH4Cl) on glutamine metabolism in cultured astrocytes of three - days - old Wistar rats were investigated in vitro. METHODS: Cultares were treated by NH4Cl with different concentration for various time periods.RESULTS: There was an obvious increase in glutamine synthetase activity and glutamine content in astrocytes under hyperammonemia. These increases were related to both ammonia concentration and time of administration . But little increase was found after ammonia in...
