Diagnostic role of intravenous urography in acute and chronic renal failure

High-dose intravenous urography (IVU) was performed 62 times in 59 patients with acute (ARF) and chronic (CRF) renal failure. The major diagnostic categories were chronic glomerulonephritis, malignant hypertension, acute tubular necrosis (ATN), and acute glomerulonephritis. The cause of the renal failure, whether CRF or ARF, oliguric or nonoliguric, could not be reliably determined by either the evolving pattern or density of nephrogram, or the size of the kidneys. Although a persistent dense nephrogram favored the diagnosis of ATN, the major correlate was a decreasing density of nephrogram as the serum creatinine level increased (P less than 0.005).     

Indium111 antimyosin for the detection of leiomyosarcoma and rhabdomyosarcoma

¹¹¹In-antimyosin monoclonal antibody complex passes through damaged myocardial cell membranes and binds to the intracellular myosin. Normal myocardial and other muscle cells show no uptake.Rhabdomyosarcoma and Leiomyosarcoma cells also contain intracellular myosin.and the cell membrane permeability is greater than normal. Significant uptake of ¹¹¹In-antimyosin was observed in patient with Leiomyosarcoma and Rhabdomyosarcoma suggesting that the reagent has a potential for the in vivo detection of these tumour types. Tumour to background ratios of 10:1 were measured in one case and in view of the fact that the site of accumulation is intracellular, antimyosin may have a potential as a carrier for therapeutic agents.
