Valiashko at the beginning of 1920’s and 1950’s. Despite some tension in the relationships between professor and the new Government, which appeared due to the evictions of a number of intelligentsia supporters outside the Republic at the beginning of 1920’s, the Bolsheviks has promptly realized that the loss of the scientific figure of such a value could cause huge damage to the best practices in the field of organic chemistry, as well as to the pharmaceutical education. Later on, M.Vailashko was given quite comfortable conditions for his research and development activity, which took its place at the faculty of Pharmaceutical Chemistry and Pharmacognosy within the walls of the Kharkiv Pharmaceutical University. The beginning of 1950’s was marked by a new increased controversy in the life of the honorary scientist with the Government.
