Journal Article
Radiograms with direct enlargement of the image were performed by means of X-ray apparatus "PEIC" designed by the firm "Svetlana", Leningrad. The status of the hand bones was studied in persons with ...posttraumatic bone regeneration, as well as angioarchitectonics of organs in experimental animals. In radiograms with direct enlargement some details characterising the process of ageing in the hand bones are observed more distinctly than in routine radiograms. The investigators succeeded in obtaining age changes in the structure of spongy substance and of cortical layer of phalanxes. The apparatus "PEIC" presents new possibilities for vital investigation of bone ostructures in experimental and clinical work, as well as to examine preparations of organs and their histological sections.
