In 147 autoradiographically examined prostate biopsy cylinders 5.4% squamous metaplasia and 6.0% transitional metaplasia were diagnosed. The average labeling index of squamous metaplasia was 4.3% and corresponded with values from non-keratinizing squamous epithelium in other locations. The labeling index of the transitional cell metaplasia was, in contrary,(More)
The lamina propria of the human tympanic membrane consists mainly of collagen fibres, but vessels and nerves can also be found as solitary elastic fibres. The pathologic alterations of the collagen fibres were examined by 47 biopsies of the tympanic membrane.

The serum of 102 pigeon breeders was examined for circulating IgG antibodies against antigens localized in pigeon intestine by the indirect immunofluorescent technique. 15 symptomatic breeders with a positive response to inhalation challenge had antibodies against mucosa tissue. The majority of asymptomatic breeders demonstrated either a fluorescence of(More)
