Paperback. Condition: New. Print on Demand. This book explores the distinctive reactions of connective tissue cells to vital dyes, using new methods to analyze the relationship between chemical constitution and biological effect in these numerous compounds. The author argues that the selective histo-pathological reaction whereby trypan blue and its dye relatives mark out certain cells and tissues, leaving others unaffected, is a phenomenon of elective storage. The phenomenon has affinities with the well-known phenomenon of phagocytosis, not only because the cells which stain most intensely are phagocytes, but also because both with large particles and with dye molecules we have an ingestion and storage of foreign material on the part of the cell. The author presents evidence that this remarkable reaction can serve as an utterly reliable criterion of cell species and of cell relationships, providing unique advantages in the analysis of the relation of chemical constitution to biological effect in these numerous compounds, and above all, an opportunity to track out in this way the underlying nature of the vital-staining reaction.
