Clinical Endocrinology in the Islamic Civilization in Iran

Endocrinology is the study of cell-to-cell connection by messenger molecules traversing an extracellular space. It has drawn on the labor of researchers from various branches of science. During the past fifty years, physiology, biochemistry, immunology and molecular biology, especially, have had the greatest impact. However, the development of our understanding of the endocrine system closely parallels the evolution of clinical sciences from prehistoric times to the present. The torch of medicine was in the hands of Muslims in the historical period from ancient Athens to the Renaissance. Iranian medical scientists during the glorious Islamic civilization had a great progress in medicine. Their excellent clinical observations and physical examinations influenced the fields of internal medicine including clinical endocrinology.
