Schisandra Inhibit Bleomycin-Induced Idiopathic Pulmonary Fibrosis in Rats via Suppressing M2 Macrophage Polarization

Table 1

The results of alveolitis and fibrosis severity classification at different time points.

Groups	Alveolitis (Day 7)					Fibrosis (Day 28)
		(0)	(+)	(++)	(+++)		(0)	(+)	(++)	(+++)
Sham	8	7	1	0	0	8	7	1	0	0
Model	8^#	0	1	1	6	8^#	0	0	2	6
Schisandra	8^#	0	1	3	4	8^#	0	3	3	2
Dex	8^#	0	3	4	1	8^#	0	2	4	2

Note: on the stage of alveolitis (Day 7), “(0)” indicates no obvious alveolar rupture and fusion; “(+)” indicates mild alveolar rupture and fusion; “(++)” indicates moderate alveolar rupture and fusion; “(+++)” indicates severe alveolar rupture and fusion; on the stage of alveolitis (Day 28), “(0)” indicates no obvious fibrous tissue hyperplasia; “(+)” indicates mild fibrous tissue hyperplasia; “(++)” indicates moderate fibrous tissue hyperplasia; “(+++)” indicates severe fibrous tissue hyperplasia. ^# vs. sham; vs. model.
