متن کاملThe Role of the Iron Stain in Assessing Intracranial Hemorrhage
The timing of the breakdown of red blood cells and organization of hemorrhage has significance in the catabolism of heme and the processing of iron, but also has a practical application in terms of assigning, or attempting to assign, a time course with respect to traumatic events (e.g. contusions and hemorrhages). Attempts to date contusions, however, have generally been unsuccessful by macrosc...
متن کاملIron as a Stain for Nucleic Acids in Electron Microscopy
An electron stain that would react with nucleic acids would obviously be a valuable addition to the techniques available for the electron microscopic investigation of cell structure. Information available from light microscopy (1-3) indicates that iron has a marked affinity for acidic residues as well as an excellent capacity for the penetration of biological materials. As a heavy metal, it was...
متن کاملA Comparison of Acquired Port-wine Stain with Congenital Port-wine Stain Using an Image Analyzer.
BACKGROUND Recent reports have proposed that there were no differences between acquired port-wine stain (APWS) and congenital port-wine stain (CPWS) except the onset of disease. Pulsed dye laser (PDL) therapy is regarded as the treatment of choice in PWS. Although in some articles, APWS might have shown a better response to PDL than CPWS, this is still controversial. It has been assumed however...
متن کاملExperiments on the action of mordants
Unmordanted haematein in aqueous solution varies in colour from yellowish orange at pH 3 to bluish magenta at pH 9. In the presence of aluminium sulphate, the colour of solutions of haematein at any particular pH depends on the number of aluminium atoms to each molecule of haematein. At pH 4-6 the colour varies from yellowish orange through dull red to rose as the number of aluminium atoms to e...
