Alterations of intermedin and its receptor system in oleic acid-induced acute lung injury of rats / 北京大学学报(医学版)

ABSTRACT

Objective:To investigate the changes of pulmonary IMD and its receptor system - calcitonin receptor-like receptor (CL) and receptor activity modifying proteins (RAMPs) mRNA in acute lung injury(ALI) induced by oleic acid of rats. Methods: Contents of IMD in plasma and lung homogenates were measured by radioimmunoassay(RIA). The lung mRNA of IMD, CL and RAMPs was determined by semi-quantitative RT-PCR. Results: Compared with control group, in ALI group, the contents of IMD_ 1-53 in plasma and lung homogenates were decreased by 20.8% and 74.5% (all P
