CHARACTERISTICS OF EPIDERMIS IN LOW ELECTRIC RESISTANCE SKIN POINTS / 解剖学报

ABSTRACT

Using morphometry and impregnation technique of lanthanum nitrate,acomparative investigation on the epidermis structure of high and low electricresistance skin points was carried out in mice and rabbits at both light and electronmicroscope level,with special emphasis on the structure of gap junctions in epidermis.It was observed that the frequency of gap junctions in low resistance points wassignificantly higher,and their diameter was larger than that in high resistancepoints,while no difference was found in other structure parameters examinedbetween the two types of skin points.It is assumed that the gap junctions may bethe structure basis for the difference in skin electric resistance.
