Sections of rat kidney stained with Masson’s Trichrome.

Abstract

<p>Low power sections of normal rat kidney (A) and rat fed a lithium diet for six months (B), in which collecting duct tubules show cyst-like dilatations. The lithium treated rats show glomerulosclerosis (C, arrow), collecting duct dilations # (C, D), and epithelial linings either greatly attenuated (D, arrow) or with enlarged cells, often appearing multinucleate (E, arrow). The cortex has areas of focal fibrosis(F). Scale bar, A, B, 200 microns; C-F, 50 microns.</p
