[Influence of the depth of retained denatured dermis on the survival rate of grafted skin in burn swine with deep partial-thickness burn].

Objective: To explore the influence of the thickness of retained denatured dermis on the survival rate of grafted skin in swine with deep partial-thickness burn.

Methods: Four deep partial-thickness wounds were reproduced respectively on both sides of spine in 7 Chinese domestic pigs. The wounds of 6 pigs were divided into 0.
