Administration of insulin 1 i.u./100 g of body weight to hypothermic rats causes a fall of glucose and lactate levels in the serum and a rise in myocardial glycogen level in relation to the group of control rats kept at room temperature and to the group of rats subjected only to hypothermia. Beta-adrenergic blockade (propranolol 0.6-1 mg/kg) caused no changes in the levels of carbohydrate metabolites in the serum of hypothermic rats but raised the myocardial glycogen level by 42% in relation to the animals subjected only to hypothermia. Simultaneous administration of both these agents during hypothermia produces a fall of the serum levels of glucose and pyruvate with a rise in the level of lactate, and raises the glycogen level in the myocardium (by about 161%) and in the skeletal muscle (by 54%) in relation to the rats subjected to hypothermia alone. Insulin and/or propranolol fail to prevent glycogen reserve exhaustion in the liver of hypothermic rats which could be due to activation of non-blocked alpha-adrenergic receptors or to the action of yet another glycogenolytic agent, e.g. glucagon, during hypothermia. 相似文献

Abstract Listeria monocytogenes produces chemiluminescence in brain heart infusion broth at 37°C in the presence of carbonate ions and acetaldehyde. This phenomenon can be enhanced by the use of luminol rather than acetaldehyde. Furthermore, there is direct relationship between the extent of growth and the level of luminescence which culminates at the end of the exponential growth. This property was used to study the susceptibility of this bacterium to two antiseptics, cetrimonium bromide and chlorhexidine, and to two antibiotics, ampicillin and chloramphenicol. Inhibition of chemiluminescence was proportional to the antimicrobial agents' concentrations and was complete at their minimal inhibitory concentrations. 相似文献
