Animal experimental study of the healing time of seawater immersion wound

Objective To study effect of seawater immersion on the healing time of wound in rabbits.Methods The wound models on skin of rabbits were made and randomly divided into two groups,control group and experimental group,8 rabbits for each group.The rabbits in experimental group had been immersed into seawater for 20 minute after wounded,while those in control group had not.The growths of wound granulation in both groups were observed,and wound areas were recorded by photos and ruler measurement.Results The mean healing time of wounds in control group Was 12～13 d,that of experimental group 16～19 d.The emerging time of granulation in control group was earlier than that in experimental group.Conclusions These findings suggest that wound healing Can be delayed after seawater immersion.
