[Experimental study on the skin by laser-assisted anastomosis]

Incisions in 35 rats were performed on the back bilaterally. Both incisions were sutured by hand with threads at equal interval. One of the incisions immediately welded by laser after suture, the others as follow. When 24 hours after suture, the stitches of the laser welded incisions were removed. The maximal strength force and histology of the bilateral incisions were measured and examined respectively at 1, 3, 7 and 14 days after the operation. The results showed: there was obviously significant differences of the strength force within 3 days between the two incisions. There was slightly inflammatory reactions, no scar and ideal healing in laser welded incisions.
