Chemists from the University of Catania (Italy) discovered that Vlad Dracula may have suffered from a rare disease that caused him to burst into bloody tears. The research was published in the journal Analytical chemistry.
Scientists have conducted a chemical analysis of three letters written by Dracula (Vlad III) during his voivodeship in Wallachia, a historic region of southern Romania, from 1448 to 1476. They applied a layer of ethylene-vinyl acetate, a polymer that holds protein molecules and parts of them (peptides), to AD Paper. Next, the scientists removed the deposited layer and, using the mass spectrometry method, studied the composition of the compounds that passed through the paper to it.
They found about 500 peptides, 100 of which are of human origin. A letter from 1475 identified three peptides found in retinal proteins and tears. Their analysis showed that Dracula may have suffered from hemolacris, a condition in which blood is found in his tears. It can be due to an eye injury or bacterial conjunctivitis, which is an infection of the lining of the eye.
Molecules that could indicate ciliopathy were also found in Dracula. This genetic disorder causes hair-like organelles in cells known as cilia to malfunction. Symptoms of ciliopathy depend on the type and can be related to the nervous system, retina, polycystic kidney disease, etc. may contain defects. Scientists have also found that Dracula may be suffering from a respiratory infection.
Scientists hypothesized that it was Vlad Dracula who left the peptides they discovered. But it cannot be denied that other people can touch the documents.
