    Notizen: There arc 2410 primary epithelial salivary gland tumours in the files of the British Salivary Gland Tumour Panel. Of these tumours, 336 (14%) involved the minor (oropharyngeal) salivary glands, and these were studied m the present investigation Individual tumours were diagnosed according to the W H O Classification The percentage of malignant or potentially malignant tumours (46%) was much higher than in major glands (18%), and in some of the less common intraoral sites all the tumours were malignant. The principal sites were the palate (54%), lips (21%) and buccal mucosa (11%), and, in these sites, pleomorphic adenoma was the most common tumour Monomorphic adenomas accounted for 6% of palatal tumours, hut 30% of lip salivary gland tumours. The most common malignant tumour was the adenoid cystic carcinoma The results arc compared with several other large surveys and with tumours of major salivary glands.

    Notizen: Summary The lectin Vicia villosa (VV) has been used for the separation of human and murine contrasuppressor T cells. These cells were characterized in cryostat sections of human palatine tonsils by double staining with VV lectin and monoclonal antibodies to macrophages, lymphocytes and their subsets using a fluorescein-rhodamine technique. VV lectin had an affinity for the CD8+ subset of lymphocytes and for a subset of macrophages within the germinal centre. The number and distribution of VV lectin binding cells was studied in paraffin sections of formalin fixed tonsils by the avidin-biotin-peroxidase technique. Positive cells in the germinal centres, mantle, interfollicular zones and fibrous connective tissue septa were quantified using an image analyser. These were found in greatest density in the interfollicular zone, correlating with the known distribution of T cells in human palatine tonsils. The binding of VV lectin to a subset of macrophages appears not to have previously been described nor have VV lectin binding CD8+ lymphocytes been demonstrated in sections of human tissues.
