[Effects of late suturing and of various locations of skin wounds on wound healing in young and old rats]. 1976

The healing of six-day-old cutaneous wounds under different conditions had been evaluated in rats. Wounds situated along the direction of cutaneous splitting displayed a slightly better healing than the other ones. In the wounds of young rats proliferation of fibroblast occurred earlier, but the more pronounced exsudative component persisted for a longer period. Regeneration of the epidermis preceded healing in the corium in all cases. All the differences mentioned disappeared when the wound was sutured two hours after the lesion had been produced, under conditions simulating the surgical procedure. The wound edges remained free of any substantial reaction. The regenerated epidermis became easily disrupted and the wound opened widely even when the histological processing was very careful. The lesioned connective tissue of the corium remained covered with fibrin.

D008722 Methods A series of steps taken in order to conduct research. Techniques,Methodological Studies,Methodological Study,Procedures,Studies, Methodological,Study, Methodological,Method,Procedure,Technique
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
