Effects of kinins on glucose metabolism in vivo.
Current concepts of the physiological importance of the kinin/prostaglandin system view these tissue factors as part of a defense system, which protects tissues from potentially noxious factors, such as hypoxia or destructive inflammatory reactions. This kinin-triggered defense reaction includes an improvement in cellular energy metabolism. The latter is brought about in peripheral tissues by an increased availability of glucose for anaerobic and aerobic glycolysis, whereas in liver tissue, energy-consuming reactions such as gluconeogenesis are attenuated. There is evidence that such favorable effects can also be produced in man when kinins are administered systemically. Prostaglandins are most likely the second messengers of kinin-induced metabolic effects. Thus, it may be advantageous to increase the availability of kinins either by exogenous infusion or by inhibiting endogenous degradation during postoperative stress or in diseases such as diabetes mellitus, in which glucose metabolism is severely disturbed.
