Huangqi Shengmai Yin Protects against Radiation-Induced Cardiac Fibrosis Injury by Regulating the TGF-β1/Smads and MMPs

Table 2

The average optical density of fibrotic factors in the HSY intervention group.

	Con	25 Gy	HDG
TGF-β1	0.192±0.023	0.371±0.018^##	0.261±0.036
Col1	0.291±0.009	0.371±0.005^##	0.316±0.012
Col3	0.419±0.025	0.514±0.024^##	0.445±0.006

The average optical density from immunohistochemistry sectioning was calculated which indicated preliminarily the effect of HSY on fibrotic factors expression level. ^##p<0.01 versus Con; p<0.01 versus 25 Gy.
