Minister of Health of the USSR G. A. Miterev in 1946 should have felt quite confident: for 7 years of work in a leading position
he had accumulated considerable experience as a health care organiser, the actions of the People's Commissariat of Health headed by
him during the Great Patriotic War were extremely successful, the post-war development of Soviet health care was going on confidently.
However, at the end of the year he was suddenly deprived of his post for attempted scientific cooperation with recent allies in the war —
the Americans: academician-secretary of the Academy of Medical Sciences of the USSR V. V. Parin during a business trip transferred to the
Soviet Union. During a business trip, Parin gave them samples of the anti-cancer drug ‘KR’ (krutsina) developed by N. G. Klyueva and
G. I. Roskin and the manuscript of a book on cancer biotherapy. The scientists were accused of anti-patriotic and anti-state actions, and
the minister was branded as an apolitical swindler. In June 1947, a trial of honour was held against N. G. Klyueva and G. I. Roskin, and in
August of the same year — against G. A. Miterev. All charges brought against them during these trials were dropped at a meeting of the
Presidium of the CPSU Central Committee in October 1959.
