Macroscopic findings of adhesions after thoracotomy

		Control group	Experimental group
No. of animals examined		5	5
Adhesion score
	Between the chest wall and lungs (1/2/3/4)	3 (2/0/1/0)	2 (0/1/1/0)
	Pulmonary interlobular adhesions (1/2/3/4)	5 (0/1/3/1)	2 (0/2/0/0)
Median adhesion score		2.5	0.0

Adhesion scores: the degree of bluntness or sharpness of the dissection process (0, no need to dissect; 1, film-like adhesion, can be dissected easily; 2, mild adhesion, can be dissected; 3, moderate adhesion, difficult to dissect; 4: strong adhesion, impossible to dissect).
