[Healing patterns of wounds inflicted by a carbon dioxide laser].

The problems concerning the wound healing by first intention and by second intention are discussed, on the instance of the wounds caused by a carbon dioxide laser. The authors claim that the cell system responsible for the resorption of necrotic tissues in the absence of purulent processes, i.e. absence of polynuclear leukocytes, is the system of mono- and multinuclear macrophages. The phase of leukocytic lysis of the necrotic tissues may be lacking during healing.
