BOAS

BOAS, Ismar (Ismar Boas), a well-known physician in Berlin (born in 1858), who established diseases of the digestive organs as a separate and independent discipline and founded the first medical journal in Europe (1896) dedicated specifically to diseases of the digestive organs, metabolism, and dietetics. The works of B. himself are devoted to the physiology and >

pathology of digestion and dietetics. B., together with Ewald (his teacher), proposed the so-called "test breakfast" as a clinical method for determining the functional capacity of the stomach (in 1884) and, together with his student Oppler, discovered the bacilli of lactic acid fermentation. B. developed the question of hidden bleeding as a diagnostic sign of diseases of the stomach and intestines. Bu-^u -c»--v

as a physician, Boas wrote a textbook: "^Internal Diagnosis and Therapy of Diseases of the Stomach", which went through 9 editions; the textbook was translated into English, Italian, Spanish, and Russian. Through his scientific and pedagogical activities, Boas showed that a practical physician can and must participate in the development of scientific questions; Boas therefore sought to simplify all research methods to make them accessible to every physician at the bedside of the patient.
