The expression of Bcl-2mRNA and P53mRNA in hippocampus after 16Hz, 130dB infrasound treatment In 1 day group, Bcl-2mRNA and P53mRNA were expressed lightly in CA1-CA3 areas in hippocampus and dentate gyrus. Blood vessels dilated lightly. In 7d group, Bcl-2mRNA and P53mRNA were more expressed in areas mentioned above. Dilation of capillaries and small vessels was more obvious. Bcl-2mRNA and P53mRNA were strong positive in endothelial cells of vessels. In 14d group, Bcl-2mRNA and P53mRNA expression was obviously increased in pyramidal cells of hippocampus and granular cells of dentate gyrus, showing deep blue staining. a The endothelial cells in some vessels were also strong positive for Bcl-2mRNA and P53mRNA. Dilation of capillaries and small vessels was lessened. In 21d group, Bcl-2mRNA and P53mRNA expression was decreased in pyramidal cells. In 28d group, little change about the expression and distribution of Bcl-2mRNA and P53mRNA was observed. Lots of Bcl-2mRNA and P53mRNA were scattered in cortex of temporal lobe around hippocampus and callosal gyrus area. Dilation of capillaries and small vessels was lessened obviously. The expression of Bcl-2mRNA and P53mRNA in hippocampus after 16Hz, 90dB infrasound treatment.
