Microspectrophotometry of Cell Nuclei Stained with the Feulgen Reaction
1. DNA contents of the individual parenchymal nuclei of rat livers during postnatal growth were estimated by microspectrophotometric apparatus, and different ploidy classes of nuclei were classified by their DNA contents. With the same material the total number of parenchymal nuclei in the liver was counted microscopically. 2. If the DNA content of nuclei encountered most frequently in several ...
متن کاملThe Use of OsO4 Fixative for Feulgen-Stained Preparations
OsO(4) has many advantages over Carnoy's fixative mixture for the Feulgen nuclear staining in the protozoan Tokophrya infusionum. While Carnoy's fluid used prior to the Feulgen reaction produces shrinkage of the macronucleus and coarse clumping of its chromatin bodies, OsO(4) preserves faithfully the size and shape of the macronucleus and its chromatin material. This finding seems to be of spec...
متن کاملDevelopment of a stained cell nuclei counting system
This paper presents a novel cell counting system which exploits the Fast Radial Symmetry Transformation (FRST) algorithm [1]. The driving force behind our system is a research on neurogenesis in the intact nervous system of Manduca Sexta or the Tobacco Hornworm, which was being studied to assess the impact of age, food and environment on neurogenesis. The varying thickness of the intact nervous...
متن کاملFEULGEN NUCLEAL REACTION I. QUANTITATIVE EXTRACTION OF FUCHSIN FROM FEULGEN-STAINED NUCL*OPROTEII~ BY TOSISUKE HIRAOKA, D.Sc
Recent advances in cytochemistry have revealed that two types of nucleic acids play important roles in the cell (for references, 1 and 2). Whereas these two types of nucleic acids, deoxypentose nucleic acid (DNA) and pentose nucleic acid (PNA), have similar ultraviolet absorption properties, they are distinguished from each other by certain color reactions based on their constituent sugars. Amo...
