Anatomy now has a step to transfer from qualitative science to quantitative science. The methods of anatomical investigation employ optical instruments. Anatomy initially described qualitative features of the structure of the body, but now it turns to transfer to new fields measuring the number, size, length, area and volume of not only, structure but also the histochemical components of the structure with quantitative analysis. In order to quantify histochemical reactions in various organs…

The Utility Value of High Voltage Electron Microscopy for X-Ray Microanalysis
TLDR
It was concluded that X-ray microanalysis using semi-thin sections by high voltage electron microscopy is of great utility for quantifying trace elements in biological specimens.
Electron microscopic radioautographic study on protein synthesis in amitotic hepatocytes of the aging mouse
TLDR
Grain counts revealed that synthesized proteins were more abundant in bin nucleate cells than in mononucleate cells at the respective aging stages, and it was demonstrated that only a few hepatocytes showing amitotic nuclear divisions were found labeled with the precursor demonstrating protein synthesis.
Electron microscopic radioautographic study on nucleic acid synthesis in amitotic hepatocytes of the aging mouse
TLDR
Grain counts revealed that RNA was synthesized significantly more in binucleate cells than in monon nucleate cells at the respective aging stages, and it was clarified that the amitotic cells did not synthesize such macromolecules as mononucleate hepatocytes did.

Cell Senescence as Observed by Electron Microscopic Radioautography
TLDR
The term “cell senescence” initially means how the cells change when they get old due to their aging, but now it also means how all the cells of an animal or a plant change in vivo due to the aging of the individual animal or plant.

TLDR
The incorporations and syntheses of various precursors for macromolecules such as DNA, RNA, proteins, glucides, lipids and others in various kinds of cells of various organs in the gastrointestinal tract such as the mouth, esophagus, stomach and intestines are reviewed.

TLDR
The technicians who produce radioautographs are named radioautographers, while those who study RAGology are scientists and should be called radioautographologists, all the results obtained from such applications should be systematized as a new field of science in the future.
