Abstract:
Objective To explore the relation of c jun antisense gene transfection and cardiomyocyte apoptosis following hypoxia and burn serum treatment Methods Burn serum was collected from Wistar rats with 30% total body surface area(TBSA) Ⅲ degree burn Rats inhaling mixed gas containing 1% O 2 was used as hypoxia model The c jun antisense gene recombinant was constructed by genetic recombination technique Cardiomyocytes from neonatal Wistar rats were cultured in vitro with hypoxia and burn serum treatment c jun antisense gene recombinant was transfected into the cultured cardiomyocytes Cardiomyocytes were stained with TUNEL for the examination of cardiomyocyte apoptosis at 12, 24 and 48 h after hypoxia and burn serum treatment In addition, the number of apoptotic cardiomyocytes was counted The results were processed statistically Results In the group with only the addition of burn serum and hypoxia(non transfected group), the numbers of apoptotic cardiomyocytes(mean per high power visual field) were 7 1?0 842, 28 4?1 635 and 13 2?1 525, respectively But after transfection of c jun antisense gene recombinant, numbers of apoptotic cardiomyocytes were 4 1?0 716,12 3?1 455 and 8 5?1 341, respectively There was a significant difference between the transfected group and the non transfected group( P
