Histochemical aspects of nucleoproteidic metabolism of human embryos. A histofluoroscopic study.

The Author, after stressing the importance of proteic syntheses in the vital processes of each cell and the role played by nucleic acids in such metabolic processes, underlines the importance of histochemical studies on nucleoproteidic metabolic in the embryo, and briefly illustrates the most important features of the fluorescent method. The Author further relates the results of his personal research conducted by means of microfluoroscopy after acridine orange chromization on histological sections of human embryos. The results are documented by the enclosed photographs, and their significance is briefly discussed.
