Abstract:
Objective To investigate the effects of hyperbaric Oxygen (HBO)exposure on Caspase-3 and Bcl-2 mRNA ex-pressions in both internal carotid artery (ICA)and basal artery (BA)in rabbits.Methods Twenty-four healthy adult New Zealand rabbits were randomly divided into 2 groups:HBO group and the control group,with each group consisted of 12 animals.The rab-bits in the HBO group were exposed to HBO at 2.2 ATA for 60 minutes each day for 3 successive days.The rabbits in the control group were normally fed without any treatment.Real-time PCR was used to detect Caspase-3 and Bcl-2 mRNA expressions in both ICA and BA in 2 groups.Results HBO significantly decreased the Caspase-3 mRNA expression [(0.038 ±0.006 )vs .(1.000 ± 0.225)]and increased the Bcl-2 mRNA expression [(1.877 ±0.1 69)vs .(1.000 ±0.364)].In ICA,HBO similarly decreased the Caspase-3 mRNA expression [(0.41 9±0.091)vs .(1.000 ±0.1 75)]and increased the Bcl-2 mRNA expression [(1.269 ±0.270) vs .(1.000±0.1 1 7)]in BA.All the differences mentioned above were of statistical significance (P <0.01).Conclusion HBO ex-erts an inhibition effect on apoptosis in cerebral vascular endothelial cells.The mechanism may be related to inhibiting the expres-sion of Caspase-3 mRNA and promoting the expression of Bcl-2 mRNA.
