Figure 2

Histology and alkaline phosphatase activity histochemistry of nasal mucosa. Routine staining of nasal mucosa with Haematoxilin and Eosin (left column) and histochemical staining of AP activity using Vector Red substrate (central column) showed strong AP activity in the mucus at the luminal surface and in the basal cell layers of the epithelium (yellow arrow); as well as in serous glands (green arrow). Levamisole, a non-specific AP inhibitor, abolished the histochemical staining of these cells (right column). Image captures at x10, x20 and x40 magnifications are shown with appropriate scale bars.
