Sudan IV Staining Method

Silver tetraphenylporphine sulfonate (Ag-TPPS) was synthesized in this laboratory and used as an electron dense stain for elastic tissue (Fig 1). The procedures for the synthesis of tetraphenylporphine sulfonate and the staining method for mature elastic tissue have been described previously.The fine structure of developing elastic tissue was observed in fetal and new born rat aorta using tetraphenylporphine sulfonate, phosphotungstic acid, uranyl acetate and lead citrate. The newly forming elastica consisted of two morphologically distinct components. These were a central amorphous and a peripheral fibrous. The ratio of the central amorphous and the peripheral fibrillar portion changed in favor of the former with increasing age.It was also observed that the staining properties of the two components were entirely different. The peripheral fibrous component stained with uranyl acetate and/or lead citrate while the central amorphous portion demonstrated no affinity for these stains. On the other hand, the central amorphous portion of developing elastic fibers stained vigorously with silver tetraphenylporphine sulfonate, while the fibrillar part did not (compare figs 2, 3, 4). Based upon the above observations it is proposed that developing elastica consists of two components that are morphologically and chemically different.

Diagnostic Histopathology

Identification of cellular phenotype by cell surface antigens in conjunction with ultrastructural analysis of cellular morphology can be a useful tool in the study of biologic processes as well as in diagnostic histopathology. In this abstract, we describe a simple pre-embedding, protein A-gold staining method which is designed for cell suspensions combining the handling convenience of slide-mounted cell monolayers and the ability to evaluate specimen staining specificity prior to EM embedding.

Previously, the author repeatedly confirmed the higher 5’-nucleotidase (5’-Nase) and lower alkaline phoaphatase (ALPase) activities in the wall of lymphatic capillaries reacted with the lead-based method relative to those of blood capillaries. The ALPase, on the other hand, is markedly higher in blood capillaries than in lymphatics. On the basis of these enzyme characteristics, the author has developed a 5’-Nase— ALPase double staining method to differentiate small lymphatics from blood capillaries at the level of the light microcsopy. Furthermore, we applied it to histochemical observation of the lead-containing reaction products of 5’-Nase in lymphatics on the same or adjacent cryostat sections using backscattered electron imaging (BEI) in scanning electron microscope (SEM). This paper presents a new applicability of 5’-Nase histochemistry by BEI-SEM to demonstrate the distribution of lymphatic capillaries in tissue blocks.
