Abstract

The organelle specificity of the uranaffin reaction was determined by subjecting two human neoplasms (a pheochromocytoma and islet cell carcinoma) to four different experimental conditions. In Uranaffin Procedure (UP) I, fixed tissue was immersed in 0.9% sodium chloride (NaCl) before reacting with 4% uranyl acetate (pH 3.9) for 24 hours. In UP II, the tissue was prepared as in UP I with the exception that the tissue was immersed in uranyl acetate for 48 hours. In UP III, fixed tissue was prepared as in UP I with the exception that tissue was immersed in 0.1M cacodylate buffer (pH 7.2) instead of 0.9% NaCl. In UP IV, fixed tissue was prepared as in UP III with the exception that the tissue was immersed in uranyl acetate for 48 hours instead of 24 hours. When UPs I and II were utilized, only three cell organelles showed electron-dense reactivity: the nucleus, ribosomes, and cytoplasmic neurosecretory-like granules. In the nucleus, the nuclear chromatin, nucleolus, interchromatinic granules and perichromatinic granules were intensely stained. The reaction product in all of the uranaffin-positive organelles had a finely granular appearance. When fixed tissue was immersed in cacodylate buffer instead of isotonic saline, a non-specific reactivity was observed. The reaction product in some areas had a distinct crystalline appearance and filled some areas of the cytosol, the cisternae of the endoplasmic reticulum, the Golgi apparatus, the perinuclear cisternae, the nucleus, nucleolus, mitochondria, neurosecretory-like granules and larger lysosome-like bodies. There was a statistically significant (p < 0.05) increase in the number of uranaffin-positive granules/μ2 when both endocrine neoplasms were reacted with uranyl acetate for 48 hours instead of 24 hours. The increase in uranaffin-positive granules using UP II did not result in an increase in non-specificity of the staining reaction.
