Histological studies on staining characteristic differences in arterial elastic fibers

Electron dense staining affinities of mouse oxytalan and elastic fibers.

The staining affinity of electron dense stains to mouse palatal elastic fibers and periodontal oxytalan fibers was assessed and compared. Tissues were stained routinely with uranyl acetate and lead citrate or with elastic tissue stains including: (1) silver tetraphenylporphine sulfonate, (2) tannic acid technique, and (3) a high iron diamine sequence. Staining results were assessed with an elec...

Histological staining techniques

The first stainings were tried by A VAN LEEUWENHOEK (apparently in the years 1714-1719) and by R VIEUSSENS (about 1684) studying their objects with alcoholic saffron dyes (LEWIS FT, 1942). At last, genuine histological work began much later when T HARTIG, C WEIGERT, J GERLACH, P EHRLICH and H GIERKE started in the second half of the 19 century with their systematic studies of natural and synthe...

Studies on Vital Staining

When large amounts of brilliant vital red are injected into the blood stream of dogs, the dye is gradually removed from circulation, and most of it is deposited in numerous phagocytic cells which are scattered throughout various organs and tissues. The dye occurs largely in the form of tiny red granules crowded together in the cytoplasm of these cells. If Niagara sky blue, a closely related dye...

Elastic Fibers in Flows

Significance of the histological and ultrastructural features of elastic fibers in diagnosis of bronchioloalveolar carcinoma.

OBJECTIVES The accurate identification of bronchioloalveolar carcinoma (BAC) from adenocarcinoma (AC) and other types of lung cancer is important from clinical perspectives; especially, when BAC is histologically-mixed with AC. We hypothesized that the elastic fibers (EF) pattern could be used as a differential marker to identify BAC from other lung cancers. The aim was to characterize the EF p...
