Gubergrits before approbation. Iryna Ivanivna spent almost the whole day with N. B. Gubergrits, a young physician who had just graduated from a medical university, since it was her first time meeting her. The two of them sat until late at the department of faculty therapy of the Kyiv Medical Institute, where Iryna Ivanivna worked at the time. Her remarks were undoubtedly well‑grounded.
