INVESTIGATION OF THE ULTRAFINE STRUCTURE OF THE KIDNEY BY MEANS OF SCANNING ELECTRON MICROSCOPE

I. THE GLOMERULUS

抄録

The fine structures of the renal glomerulus, Bowman's capsule and the transitional area from Bowman's capsule to the proximal tubule have been studied after preparing with critical point method by field emission type scanning electron microscope. The structures of both the normal glomerular capillary wall and the basement membrane with three layers have been particularly examined. From the fine structure of the transitional area from Bowman's capsule to the proximal tubule, it has been suggested that this area has something to do with the flow of glomerular filtrate.
