ABSTRACT

AIM:

To explore the relationship between apoptosis in the lung tissues and lung ischemia/reperfusion injury,and to observe the effects of human thioredoxin (hTrx) on apoptosis in lung ischemia/reperfusion injury.

METHODS:

The single lung in situ ischemia/reperfusion animal model was used. Eighty four Wistar rats were randomly divided into control group (control),groups of ischemia for 1 h and reperfusion for different times (IR1h,IR3h,IR5h),and groups of IR + human thioredoxin treatment (IR1h + hTrx,IR3h + hTrx and IR5h + hTrx). Transmission electron microscope (TEM),terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and immunocytochemistry techniques were used to observe apoptosis,apoptosis signal-regulating kinase 1 (ASK1) and expression of Bcl-2 and Bax in various phases of lung ischemia/reperfusion.

RESULTS:

Cell apoptosis in lung tissues was significantly high,ASK1,Bcl -2 and Bax protein were upregulated in lung tissues of lung ischemia/reperfusion injury as compared to control (all P
