Abstract
The distribution of203Hg-neohydrin has been studied by means of injection into the tail vein of rats. We know that the chief distributed organ of203Hg-neohydrin is the kidney and on the autoradiogram the blackend dots there are predominantly into the convoluted tubuli.
When ten microcuries of203Hg-neohydrin were injected into the vein of the normal adults also and patients with nephritis or liver diseases disappearance of203Hg-neohydrin from blood stream was proved as follows: in the normal adult it gets to half within one hour and in the patient with nephritis or liver diseases the disappearance of203 Hg-neohydrin to half takes longer. The rate of prolongation was parallel with severity of illness but independent probably of grade of oedema or hypoproteinemia.
We think that the renal scan is a kind of the most useful research techniques for evidence of the damage of renal parenchyma and moreover, the renal scan with the pyelography is the most advantageous method with regard to differential diagnosis of the upper abdominal tumors, and this technique gives no pain to the patients too.
