Introduction Bismuth subgallate (BS) is a yellow and odorless powder that has hemostatic astringent properties. Some otorhinolaryngologists and dentists currently use this substance to enhance wound healing. Objective The objective of this study is to evaluate the effects of bismuth subgallate on wound healing, through the analysis of inflammatory process, collagen production, and angiogenesis....

A new technique for the staining of the corneal endothelium combines the actions of the vital stain trypan blue and the intercellular stain alizarin red S. The technique is an improvement over former staining methods, because it defines both viable and nonviable cells and thereby permits an investigator to accurately quantify endothelial cell damage.

The excellent adaptability of Callithrix jacchus to life in captivity presents advantages comparison other nonhuman primates that are used experimental models for biomedical research, which explains the increasing scientific interest investigating anatomical characteristics this species. Owing relative scarcity publications on descriptive morphology heart C. jacchus, aim study was quantify pres...

The color in the pigment of the stain is caused when molecules absorb light in the visible wavelength range (400-780 nm) [10]. The wavelengths that are not absorbed will be reflected instead and are visible to the human eye. For example, red wine stains are red because the molecules absorb every wavelength that is not in the red range, and the red wavelengths (500-600 nm) are then reflected to ...

Macrophages are responsible for removing the extravasated blood that forms a bruise. Aspects of this process, such as how long it takes erythrocytes to be phagocytosed and iron demonstrated using Perls stain, not established. This work sought assess possibility macrophages in cell culture address some unknowns processes resolution Human peripheral monocytes were obtained from buffy coats provid...

UTILITY: (1) Assess degree of fibrosis. H&E stain is not reliable for demonstration of fibrosis especially in early stages. Pericellular fibrosis around the central vein in steatohepatitis can be difficult to identify on the H&E stain. (2) Distinguish fibrosis from necrosis. In acute hepatitis, areas of confluent necrosis can be difficult to distinguish from fibrosis and can lead to an erroneou...

Clinical isolates of the opportunistic pathogen Mycobacterium avium complex (MAC) undergo a reversible switch between red and white colony morphotypes on agar plates containing the lipoprotein stain Congo red. Compared to their isogenic red counterparts, white morphotypic variants are more virulent and more resistant to multiple antibiotics. This report shows that the two-component regulatory s...
