RESUMO
Objective: To interview the role of CGRP to hepatic microcirculation in acute liver injury induced by coneanavalin A(Con A). Methods: Sixty Kunming rats were divided into three groups randomly(n=20), acute liver injury was established by injection with 20 mg/kg Con A through the tail vein. A saline control group was established by injection with saline. In CGRP-administered group, CGRP was given to rats 30 min before Con A injected. Ten mice in each group were used to observe the average liver blood flow volume and concentration by laser-doppler flow-instrument, and the other ten rats were observed the hepatic microcirculation velocity in vivo by an inverted microscope. Liver damage was assessed by histological evaluation after the rat had been killed. Results: Compared to the injury group, the average liver blood flow volume and velocity were significantly increased in CGRP-administered group, meanwhile, the pathological injury was markedly alleviated, whereas the blood concentration was almost the same. Conclusion: CGRP can decrease the dysfunction of hepatic microcirculation by means of improving the tissue perfusion, and alleviate the pathological damage during acute liver injury.
RESUMO
OBJECTIVE:To summarize the effects of compound glycyrrhizin injection(GL)on hormone withdrawal syndrome(HWS)in SARS patients.METHODS:Using contrast design,the HWS of 134 cases of SARS who had received hormone theropy was retrospectively analysed.RESULTS:Administration of GL could descend the incidence rate of symptoms of HWS,of which the incidence rates of short breath and chest distress,the main symptoms of SARS patients,dropped from 24.5%and 22.6%to 3.6%(P≤0.01)and 7.1%(P≤0.05)and the incidence of asthenia,musculoarthragia and headache decreased from 13.2%,15.1%and 10.4%to 7.2%,14.3%and 0%respectively.The number of patients with elevated ALT reduced(P≤0.01).CONCLUSION:GL can decrease the incidence of HWS.
