Radioautography of Histologic Sections of Human Testicular Tissue

Abstract

Two techniques suitable for qualitative radioautographic analysis of histologic sections of human testicular tissue are described. In one, deparaffinized wet slides are coated with photographic emulsion resulting in significant improvement in preservation of histologic quality of the tissue section. In the second procedure stained and processed slides are coated with a thin layer of H.S.R. prior to coating with photographic emulsion. This procedure allows excellent preservation of the stained tissue section and also enables visualization of the reactive cell and its radioautographic image at two different focal planes. The techniques can be applied with equal advantage to histologic preparations of other tissues.
