<I>The biodistribution of nanometer-sized colloidal particles (nanocolloids, Solco-Basle Ltd.) was examined in six rabbits with turpentineinduced abscesses in the masculature of their hind legs.</I><BR><I>A </I><SUP>99m</SUP>Tc <I>labelled colloids with a mean particle size less than 100nm were administered to each rabbit intravenously. The biodistribution of the tracer was studied with a gamma camera 1, 3, and 24 hours after injection. Prominent uptakes were demonstrated in the liver, spleen, bone marrow, kidneys, and urinary bladder. On the other hand, the abscess and surrounding inflammatory edema was depicted as unclearly margined faint hot spot.</I><BR><I>Subsequently, the rabbits were sacrificed and activity per gram tissues were counted with a well-type gamma counter. Although the results were almost in agreement with a gamma camera study, it was noticed the activity counts in the abscess was significantly higher than that of control muscle.</I>
