RESUMEN
Lipoxins, metabolites of arachidonic acid , are a strong“braking signal” towards inflammatory reac-tion.Due to their anti-inflammatory and pro-resolving properties , lipoxins have emerged to be the central targets in the re-search on inflammation .The present article reviews the research advances of synthesis , biological effects and the protective role of lipoxins in the diseases of liver , pancreas , stomach and colorectum , thus providing a novel approach for the treat-ment of digestive diseases .
RESUMEN
OBJECTIVE:To determinate the plasma concentration of ropivacaine in rabbits by HPLC,and study the secu?rity of ropivacaine in rabbits.METHODS:Nine rabbits were injected with ropivacaine drop by drop with a speed of1mg/(kg?min)until the rabbits died.RESULTS:The mean plasma concentration of ropivacaine in rabbits was224.54?107.45mg/L when the rabbits died.CONCLUSION:Ropivacaine has high security in rabbits.
