99mTechnetium-unithiol complex, a new pharmaceutical for kidney scintigraphy.
The investigations were carried out with a newly synthesised, original 99mTc-Unithiol complex (Unithiol-2,3-dimercaptopropansulphonate). It accumulates in the kidneys and enables their scintigraphic examination at 90--180 minutes after the administration. The study was performed on rats, rabbits and dogs. 99mTc-Unithiol complex accumulation in rat kidneys was 34,9%, 44,5% and 67,8% of dose after 1, 2 and 3 h respectively. Good reability of the scintigraphic picture of the kidneys in rabbits and dogs confirms the accumulative capability of the complex in these organs. It was found by means of ascending paper chromatography that the purity of the 99mTc-Unithiol complex exceeded 90%.
