Figure 7. Pathological evaluations and scoring of rat lung tissues.

Figure 7

I. Rat lung tissue under a light microscope. A. Rat lung tissue had a relatively complete structure in the normal control group. B. Rat lung tissue in rats with LPS-induced injury. C. Rat lung tissue in P1 group. D. Rat lung tissue in MP12 group. Edema: black arrow; congestion: white arrow; inflammatory cell infiltration: gray arrow. II. Pathological scoring for lung tissue:(the scores of control group is zero) ▴compared with the LPS group: P<0.01; ▵ compared with the P1 group: P<0.01;★compared with the P1 group: P<0.05.
