99mTc-unithiol complex, a new radiopharmaceutical for kidney scintigraphy. IV. Autoradiographic localisation of its cellular distribution in the kidney.
The distribution of 99mTc-Unithiol complex was studied by macro-autoradiography in rats and in rabbit kidneys, and the presence of activity in the renal cortex was easily demonstrated. Using micro-autoradiography, the accumulation of activity in various parts of the nephron was observed to concentrate in the cells of the proximal and distal tubuli to a larger extent than in the glomeruli.
