Fig. 4 — Immunohistochemical distribution of inducible nitric oxide synthase (iNOS) 24h following an infusion of LPS. Control submandibular glands (a) showed little expression of iNOS whilst 24h following an infusion of LPS (b) iNOS was widely distributed in acini (arrow) and inflammatory cells (arrow-heads). Such increased iNOS expression was observed in 3 LPS treated glands that were examined. Magnification x125.
