In experimental study on pigs was designed to evaluate the changes of the vessel density of super thin skin flaps.By means of stratified sampling, isotropic uniform random section, the vessel density of the supor thin skin flap was obeerved under the MIAS-200 image analyzer. The results showed that the remarkable changes of vascular density were found to begin on the 5th day after operation and was first appeared in the distal port of the survived flap,then,it proceeded gradually from the distal proximally.
An experiment on the effect of phenytoin onthe healing of wounds of rabbits with the selfcontrol was otiserved from the followingparameters: the reduction of surface area ofwound, the time required for the healing ofwound, examination of the wound tissues bylight and electronic microscope , and the bacterialcounts of the wound. It was noted thatphenytoin was capable to increase the rate ofwound healing, reduce the time of woundhealing, enhance the growth of healthygranulation tissue, enh...
