  1. NADPH-diaphorase histochemistry was performed on cyrostat sections, and NOS1 immunohistochemistry on cryostat or paraffin sections depending on the antibody used (see Material and Methods). The numbers indicated in the table represent the number of positive tumours over the total number of tumours studied.
