Renal tumours were induced in dietary-primed rats by injection of dimethylnitrosamine. Control and tumour tissue was excised at varying periods and maintained in short-term organ culture in the presence of 3H- or 14C-fucose. The plasma membranes were then isolated, and the isotopic profiles of normal kidney and renal tumour membrane proteins were established, using polyacrylamide-gel electrophoresis in dodecyl sulphate. Several fucose-containing glycoproteins of the plasma membranes were found to alter upon neoplastic transformation: 4 increased and 3 decreased. The probable identity of 2 of these proteins is indicated: alpha-foetoprotein is one of the glycoproteins which increased, whereas neutral endopeptidase decreased in the tumour membranes. Fluorescein-labelled lectin binding by the kidney tissue was also found to alter upon transformation. The most marked changes were an increase in sialic acid (neuraminidase-sensitive) and galactosamine (Ricinus communis agglutinin Type I) in the nuclei of some neoplastic cells and some hyperplastic-tubule cells.

Plasma protein extravasation in the upper airways of anesthetized guinea pigs was measured with the FITC (Fluorescein isothiocyanate)-dextran technique. The effect of selective tachykinin (NK1 and NK2) receptor agonists and antagonists, capsaicin or antigen was studied. The tachykinin NK1 receptor agonist, [Sar9]substance P sulfone, induced an increase in FITC-dextran extravasation which was blocked by the nasal application (30-100 nmol/kg) of the tachykinin NK1 receptor antagonist FK888, but not by 1 micromol/kg of the tachykinin NK2 receptor antagonist, MEN10,627. The tachykinin NK2 receptor agonist, [betaAla8]neurokinin A-(4-10), had no effect on dye leakage. FK888 (30 nmol/kg intranasal) abolished the increase in the tracer recovery induced both by antigen and capsaicin. Conversely, the intranasal administration of MEN10,627 (0.1-1.0 micromol/kg) significantly reduced capsaicin-induced and only marginally inhibited antigen-induced increase in plasma protein extravasation. Pretreatment with the neutral endopeptidase inhibitor, phosphoramidon, increased the effect of all inflammatory agents. These findings show that the plasma extravasation of the upper airways induced by exogenous or endogenous tachykinins is primarily mediated by tachykinin NK1 receptors. This inflammatory response could be controlled by locally applied tachykinin NK1 receptor antagonist.
