ABSTRACT
The expression of intercellular adhesion molecule-1 (ICAM-1) in the pathogenesis of heroin-induced acute lung injury (ALI) in rats was investigated. The model of ALI was established by intravenous injection of heroin into tail vein in rats. Thirty-six rats were randomly divided into heroin-treated groups (1 h, 2 h, 4 h, 6 h and 24 h) and normal control group. Changes in histopathologic morphology and biological markers of ALI were measured. The expression of ICAM-1 in lung tissue was detected by using immunohistochemistry and RT-PCR. The results showed that the W/D ratio and protein contents in BALF of the heroin-treated groups were significantly higher than that of the, control group (P<0.01). The histopathological changes in the lung tissue were more obvious in heroin-treated groups. The ICAM-1 protein and mRNA expression in the lung tissue of heroin-treated groups were significantly increased as compared with that of the control group (P<0.01), and correlated with the ALI parameters in a time-dependent manner. Increasing of ICAM-1 expression was involved in the formation of heroin-induced lung injury. Furthermore, the level of expression was positively correlated with the severity of lung injury.
