Pulmonary vein walls of dogs were composed of 3 layers: the tunica intima, tunica media and tunica adventitia.

Hybridization of cDNA probe and gene chip was carried out, gene chip was scanned with Scan Array3000, and results were analyzed with ImaGene 3. 0. Result: 1 Toluidine blue staining of semithin section showed: compared with control group, the boundary of tunica intima, tunica media and tunica adventitia was not distinct, tunica intima and internal elastic membrane was thickened and multilaminar.

Results①The tunica intima and tunica media of the BVs were thin, the tunica adventitia was thick. No complete layer of smooth muscle was found in the tunica intima, the SMC with single elliptical or rod-shape nuclear, fusiform in shape and different in length, ran longitudinally and distributed unequally in the wall of BVs, intercrossed with each other, endothenial cell wasn't covered fully sometimes.
