Alvaro Osorio (Ozorio) de Almeida, Brazilian physiologist (Porto Alegre 06 November 1882 – Rio de Janeiro 06 May 1952) Brother of physiologist Miguel Osorio
de Almeida ACHIEVEMENTS
Created a phenolphthalein relative, the nephthol-β and developed a new treatment method for
ancylostomiasis employing it Invented ureterovenous anastomosis (1927) Established the oxygen tolerance range under pressure
in little mammals Demonstrated that radiations produce pathological changes in tissues through free radicals formation Recherches sur l’action toxique des hautes pressions d’oxygene. Comp. Rend. Mem. Soc. Biol. 115:1225-7, 1934 Developed a technique for central nervous system
destruction employing injection of hypertonic solutions of sodium chloride into
cisterna magna under pressure (1923) Created cineradiotherapy (1937) and other roentgen therapy
techniques Regarded as world pioneer on hyperbaric hyperoxia
related to leprosy and gaseous gangrene treatment (1937-8) Discovered that basal metabolism depends on usual metabolism
Discovered that basal metabolism of a person with
moderate physical activity decreases gradually when one moves from a temperate
climate to a tropical climate without change (his/her) life mode (it no occur
in active people) Suggested that
metabolic rate was proportional to the normal average metabolism, depending on
the individual lifestyle, the climate where one lives and the skin surface Developed a new method for determination of
calorimeters constants (1917) Developed a new technique for studying equilibrium
between water, organic salts and organic compounds in animals (1928) A new process for determination of projection velocity
of nervous influx by hearing (1924) Performed original studies on cellular oxidations With Gley studied endocrine organs of many Brazilian rodents and marsupial mammals (1923) Demonstrated the influence of cutaneous reflexes upon metabolism (1926) With O.B. de Couto e Silva & E. Roquette Pinto. Sobre um novo veneno sagitário dos índios Purus-Borós. Anais Acad. Bras. Ciencias (1926) Authored a number of studies about temperature and metabolism of weasel, armadillo and bat Developed a process for obtaining and storing solar
energy (1927) DID YOU KNOW? Famous French scientists like Gley, Lapicque, Pieron, Laugier, Hadamard, Langevin, Marie and Irine Curie beyond Albert Einstein visited his laboratory LINKS http://www.dichistoriasaude.coc.fiocruz.br/iah/pt/verbetes/almalvoz.htm (in Portuguese; bibliography) |
