[Mechanism of injury of intestine, liver and lung in acute cholangitis of severe type model and the protective effect of huoxue qingjieling].
Lung capillary permeability was measured with 125I labelled bovine serum albumin, the progression of hepato-cellular injury was quantitatively assessed using atriphenyltetrazolium chloride assay, injury of small intestinal mucosa was determined by the changes of diamine oxidase (DAO) level, content of oxygen free radicals (OFR) was measured by electron spin resonance spectrometer and levels of phospholipase A2(PLA2) of intestine, hepatocellular viability were observed by bioassay methods respectively. The results showed that function of lung, liver and intestine was seriously injuried in ACST rats. These injuries demonstrated by increase of capillary permeability and decrease of hepatocellular viability as well as DAO in intestinal mucosa (P < 0.01) in comparing with control, while the levels of OFR and PLA2 in the above-mentioned 3 organs were elevated simultaneously (P < 0.01). As for the comparison of efficacy of different treatment, Huoxue Qingjieling was the best one, the bile duct decompression or ampicillin showed little benefit on injury protection even aggravated in some tissues, they displayed a close relationship with their influence on the OFR and PLA2. Besides, the levels of OFR or PLA2 in various tissues were different from each other, therefore, the serum levels of OFR or PLA2 can not reflect the real levels occurred in organ or tissue level.
