The main attention of health service in Russia is paid to prophylaxis. One of the most important tasks in the fight against different diseases is the early detection of the first signs of the disease. We pay much attention to the popularization of medical science among the population. We believe that one the main available methods of preventing the spread of diseases is health education. The press, cinema, radio and television are very helpful for this purpose. The basic medical unit in our country is the polyclinic. We have policlinics for the adult population and for children. Ambulant patients are seen at the policlinic by the district doctors. A patient who is ill at home is visited by his district doctor. The doctor works 6 hours a day. For the district doctor this is made up of 3 hours in consultation at the policlinic and 3 hours in visiting patients in their homes. The emergency ambulance service operates day and night and is free of charge. The ambulances are equipped by diagnostic, respiratory, anesthetic and electro-therapeutic apparatus, blood-transfusion and other equipment. There are several specialized hospitals in Russia for the treatment of particular diseases – infections, psychiatric diseases, cancer, ophthalmological diseases and others. Some words must be said about the Mother-and-Child Health Care Centre in Moscow. This centre concentrates effort not only on traditional problems of obstetrics and gynecology but also on research in normal physiology of the female organism. The main task of this centre is to ensure the birth of a healthy child. The centre developed new methods of disease prevention, diagnostics and treatment. Much attention in our country is paid to the scientific problems, concerning the prevention and treatment of cardiovascular, viral and oncological diseases, the problems of gerontology, medical genetics, immunology and the creation of artifical organs.
