14. The clinical value of urinary cytology: 12 years of experience with 615 patients.
AIMS--To analyse the diagnostic value of cytological examination compared with histological findings in a large series of patients (n = 615) with tumours of the urinary tract epithelium. METHODS--Cytological examinations (n = 785) after bladder washing and exfoliative cytology were retrospectively compared and correlated with histological findings. In additi

19. Keratin profiles of normal and malignant oral mucosa using exfoliative cytology.
AIMS--To assess keratin profiles from smears of malignant and contralateral normal oral mucosa as part of the development of a screening procedure for oral cancer based on exfoliative cytology. METHODS--Smears were taken from oral cancers (confirmed by biopsy) and from the contralateral site of 20 patients. Using a panel of antikeratin antibodies, the kerati

20. Possible use of phosphohexose isomerase as a preliminary to exfoliative cytology in screening for cervical carcinoma
The activities of phosphohexose isomerase and 6-phosphogluconate dehydrogenase have been studied in the vaginal fluid of women from the gynaecological departments. Women from these departments gave a very high false positive rate, though no cases of carcinoma in situ were not detected by estimating phosphohexose isomerase levels. It gave considerably better

21. Effect of radiotherapy on oral mucosa assessed by quantitative exfoliative cytology.
The effect of radiotherapy on normal buccal mucosa was investigated using the quantitative techniques of cytomorphology (measurement of nuclear and cytoplasmic area) and DNA cytophotometry. These techniques were applied to smears obtained before, during, and after irradiation. Nuclear area and cytoplasmic area increased and DNA values were abnormal in most c

22. A monoclonal antibody against basal cells of human epidermis. Potential use in the diagnosis of cervical neoplasia.
A murine monoclonal antibody was generated against human skin cells obtained from psoriatic plaques. The antibody, called VM-2, recognizes an epitope expressed on the basal cell layer of human skin and other epithelia. VM-2 also binds to cultured cells from a variety of human carcinomas including HeLa cervical carcinoma, A-431 vulvar carcinoma, A-549 lung al

23. Practical problems of diagnosing trichomoniasis in women.
Analysis of eight groups of data collected at varying intervals during a period of seven years showed fluctuations in the sensitivity of tests to diagnose trichomoniasis in women. The best results were obtained from fresh, correctly prepared Diamond's medium, Feinberg-Whittington's medium, and modified Squires and McFadzean's medium (which showed 82% to 94%

24. Aspiration biopsy of thoracic lesions
We have performed percutaneous needle aspiration biopsy of intrathoracic lesions under fluoroscopic control on 50 patients. Lesions as small as 1 to 1·5 cm. in diameter were aspirated. Thirty of the 36 cases of malignant neoplasm were diagnosed by this method. Of the 14 non-neoplastic cases, granuloma was diagnosed in two, and in eight of the remaining 12 t
