Abstract
BACKGROUND: Historical review on the early development of organotherapy for diabetes [pancreatic extracts (PE)] and its relationship with the social and political circumstances. AREAS OF UNCERTAINTY: The diagnosis of diabetes relied only in the presence of glycosuria and cardinal symptoms. Blood glucose determinations were not regularly available, requiring large volumes for sampling. Micromethods for glycemia were developed just in the last years of the investigated period. Hypoglycemia remains undiscovered. Isolation and purification of PE were difficult tasks due to the unknown chemical structure of the antidiabetic hormone.

Bliss); Diabetes, Its Medical and Cultural History (D. von Engelhardt); Brown-Séquard (M. J. Aminoff); Diabetes: The Biography (R. Tattersall); The Endocrine Organs (E. Schäfer); The Internal Secretions (E. Gley); Health, race and German politics between national unification and Nazism, 1870-1945 (P. Weindling). THERAPEUTIC ADVANCES: Demonstration that diabetes is a pancreatic disease. The outstanding progress of medical physiology led to the birth of endocrinology and the key concepts of homeostasis. Experimental scientists designed new procedures for complete pancreatectomy and elaboration of PE containing the antidiabetic principle. Organotherapy achieved complete success in the treatment of myxedema and partial success in the treatment of experimental and clinical diabetes. CONCLUSIONS: The organotherapy of diabetes was an obliged step to facilitate the identification of the antidiabetic hormone. Organotherapy of diabetes was a paradigm for the integration of basic and applied knowledge about hormone action and development of endocrine pharmacology.
