During the Second World War, while being evacuated as part of the medical institute in Chkalov (Orenburg), D.O. Alpern performed significant research on the wound process, shock and trophic ulcers, which had not only theoretical but also practical significance for martial law surgery and therapy, and which are still relevant today.
The main scientific works of the professor are devoted to the pathophysiology of the nervous system, neurohumoral regulation, the pathochemistry of inflammation and the pathogenesis of allergic reactions. The scientist established the trophic influence of the nervous system on the permeability of blood vessels and tissues, the role of mediators in the disruption of the reflex activity of the nervous system, in the pathogenesis of inflammation and trophic ulcers (1928).
D.O. Alpern studied the role of chemical factors and nervous excitation in the pathogenesis of a number of diseases, established the desensitizing and anti-inflammatory effect of pituitary extracts (1935), as well as the role of adenine nucleotides in the pathogenesis of inflammation (1951). He proposed the medical drug mesophysin.
D.O. Alpern devoted a large cycle of research to the problem of inflammation. "Among the old and new problems of pathology, the problem of inflammation always remains relevant," wrote Danylo Alpern.
He was not only a great scientist, but also a talented teacher and a brilliant lecturer. His lectures for students and speeches at scientific forums left an indelible impression.
D.O. Alpern made a huge contribution to the formation of pathophysiology as an academic discipline. He conducted systematic work to improve the pathophysiology course program, and he was the first to create methodological instructions for a workshop for students. A great deal of work was done to equip the department with equipment.
D.O. Alpern was an active participant in Union and republican congresses and conferences, international congresses and symposia.
At the XV International Congress of Physiologists, the scientist presented new clinical and experimental data on vegetative asymmetries of the autonomic nervous system based on many years of work on the regulation of metabolism.
D.O. Alpern's scientific and pedagogical activities were combined with extensive social work. He was a member of the Academic Council of the Ministry of Health of the USSR and Head of the Kharkiv Branch of the Scientific Society of Pathophysiologists, an honorary member of the International Antirheumatic Society, and a member of editorial boards of various medical journals.
The professor was deeply devoted to science, and he devoted his entire life to it.
