ABSTRACT
With the electron microscope, changes in the epithelium and subepithelial tissue in Reinke's oedema are more clear. An intense widening of the intercellular spaces is observed, with the presence of a strongly electron dense substance. In some cells, especially in the cells of the stratum spinosum and in the endothelial cells of the capillary vessels, intracytoplasmic cystic formations are observed, which in some cases are located in nuclear invaginations. However, these cystic formations can give a false impression that they are intranuclear if an incorrect tissue section is made.

The salivary glands of 32 patients were studied with scintillography. Ten patients were normal controls, while the remaining 22 patients had various disease processes involving their salivary glands. Scintillography was performed by two methods: the standard technique utilizing intravenous isotope injection and selective scintillography. According to this latter method, the radioisotope used is administered only to the gland under investigation by selective catheterization. The present study includes the results of this work, the advantages and disadvantages of each technique employed, and the indications for further use of selective scintillography.
