In his spare time he learned German, you would later English and French. He began studying medicine at the Universidad Central de Venezuela between September of that year and 1898. Did not complete the second year, despite its high ratings, but the learning that took in that short period of training, the lessons he received from his coach Dr. Santos Aníbal Dominici, the Pasteur Institute in Caracas, where he became familiar with the bacteriology and microbiology technique have been outside at the Department of Internal Medicine, also directed by Dr. Dominici in the Hospital Vargas, and performance that had the coach of the chairs of Dr. José Gregorio Hernández, between August 1899 and April 1903, on techniques of parasitology microscopic staining of microbes the development of culture media, and inoculation of pathogens in laboratory animals, prepared him to be named, on 18 February 1902, chief of the Laboratory of Histology and Bacteriology of Vargas Hospital, developing a short but fruitful research work.
suggestion of Dr. Hernandez, one of the first ideas was to study the structure and physiology of the nervous system. His contribution to the history of medicine consisted of detailed and systematic analysis, based on the analysis of cases of hookworm infection as a cause of severe anemia in rural areas. The investigations found the parasite Necator americanus and their eggs; findings extremely useful in establishing the treatment of anemia. In late 1904, on a trip to the plains succeeded in establishing the cause of "Derrengadera" or "stupid fever" of the horses to find single-celled organisms or Trypanosomes in the blood of animals affected.

A Rangel was denied a scholarship to study tropical medicine in Europe.

An unfortunate end that gave birth two months later to play "Shadows" of Sallust González Corners. Dr. Enrique Tejera
