Injuries of operations were caused to carotid arteries of Watanabe heritable hyperlipidemic (WHHL) rabbit and a morphological study of the course of repair was made. Japanese white rabbit (JWR) were treated exactly same as WHHL, and their course of repair was compared and examined as control. One week after operation, both WHHL rabbit and JWR showed edematous thickening of a intima, increase in grade of thickening which was continued until two of three months after operation was observed, however gradually decrease thereafter. In case of WHHL rabbit, thickened intima at suture portion was formed by smooth muscle cells migrated from media. Foamy cells were not observed here.
