Institute of Burn Research, Southwest Hospital, Third Millitary Medical University, Chongqing.

30% third degree burn model of Wistar rat was used in this experiment. The animals were divided randomly into three groups (normal control, burn, and platelet-activating factor antagonist treatment). After poured E. coli which labelled with acridine orange into intestine, the rats were killed at 6, 12, 24, and 48 hrs postburn, the bacteria in mesentery lymph node (MLN), liver and pulmonary organisms were cultured and counted, also observed by fluorescent microscopy directly. The results showed that, in PAF antagonist (WEB2170) treatment group, the quantity of bacteria in MLN, liver and lung were decreased significantly (P < 0.001). The labelled bacteria in MLN, liver and lung of burn group were 100%, 80.0%, and 50.0% respectively compared with 40.0%, 30.0%, and 20.0% in treatment group. It is suggested that WEB 2170 could protect the intestine from bacteria translocation after burn injury.

D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random
D002056	Burns	Injuries to tissues caused by contact with heat, steam, chemicals (BURNS, CHEMICAL), electricity (BURNS, ELECTRIC), or the like.	Burn
D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
