The late Greco-Roman and Byzantine contribution towards the evolution of laboratory examinations of bodily excrement. Part 2: sputum, vomit, blood, sweat, autopsies.

摘要

Although the establishment of medical laboratory institutions was a continuous process that matured only after the 16th century, several attempts had already been made to attain a diagnosis by investigating bodily excrement. In the first part of our work, published in a previous issue of this journal, we presented data on urine, sperm, menses and stools. In this paper we present data on sputum, vomit, blood, sweat, and autopsies, thus completing the list of human materials used for laboratory examinations. All the data used are extracted from codices of Late Antiquity and Byzantium and translated by us. We did not study medical texts from the other great ancestors of Western medicine, namely Arabic and Jewish writings. From the texts cited, it is apparent that the lack of technological means was no obstacle for the doctor to create an examinational in the excrement with the pathophysiological mechanism that induced them, solely with the use of the senses. This not only applies to the examination of urine, as is commonly assumed, but also to many other excrements of the upper and lower orifices of the body, as well as the human body as a whole.
