A method of abrasive biopsy of the peripheral bronchial tree is described. Forty-nine patients with peripheral pulmonary lesions have been investigated, and at bronchoscopy brush biopsies have been ...performed. In 13 cases a firm diagnosis of bronchial carcinoma was made and in nine patients atypical cells were reported. Two of the latter were found on further investigation to have had no carcinoma and one showed squamous metaplasia only on surgical biopsy. In nine patients a false negative result was obtained. These results suggest that the routine use of brush biopsy during bronchoscopy performed in the investigation of peripheral pulmonary lesions helps to increase the accuracy of diagnosis.
Haemagglutination inhibition tests are easy to perform and easy to read. The results are reproducible and are not subject to the vagaries of supply and temperament inherent in tests using living ...creatures. In a series of tests with Prepuerin done in parallel with the Hogben test the former has shown a higher sensitivity. There have been three false positive results with Prepuerin tests in the series but it was not established on general grounds that pregnancy was not in fact present.
