Ultrastructural changes of the rat renal glomeruli in the early phase of renovascular hypertension. | Electron microscopic studies were carried out on rat kidneys during the early phase of "two-kidney" Goldblatt hypertension. Pathologic ultrastructural changes (confluence of foot processes of the podocytes, formation of intercellular juctions between them, etc.) and an enhanced permeability to ferritin were found in th... | 532,716 | [
