La cardiología nació con la ciencia médica moderna / Cardiology was born with the modern medical science

La ciencia médica moderna nació en la época posrenacentista y comenzó a afianzarse a mediados del siglo XVII por obra de físicos, fisiólogos y biólogos, quienes eran discípulos directos o indirectos de Galileo. El descubrimiento de la circulación sanguínea por Harvey se considera actualmente como el único adelanto en fisiología de principios del siglo XVII, comparable a los avances contemporáneos de las ciencias físicas. La historia de esta hazaña podría escribirse fácilmente desde el punto de vista del avance progresivo del conocimiento. Se ha afirmado con toda justicia que el descubrimiento de la circulación de la sangre es la primera explicación adecuada de un proceso orgánico y el punto de partida del camino hacia la fisiología experimental. Puede aseverarse, por lo tanto, que la ciencia médica moderna no surgió de manera subitánea y global, sino que se estructuró gradualmente desde mediados del siglo XVII, por la senda seguida por William Harvey, a la luz del pensamiento de Galileo.

Modern medical science was born in the post-Renaissance age and began to consolidate towards the middle of the XVII century thanks to physicists, physiologists and biologists, most of whom were direct or indirect pupils of Galileo. The discovery of blood circulation by Harvey is now considered the only progress in physiology at the beginning of the XVII century, comparable to the current advances seen in physical sciences. The history of this exploit could be written from view point of the progressive advance in knowledge. In his experiments, Harvey referred to the authentic not imaginary experiments, and put forward irrefutable quantitative arguments. We can therefore claim that his discovery of blood circulation was the first proper explanation of an organic process and the starting point leading to experimental physiology. So it seems justified to assert that modern medical science did not all rise suddenly, but was gradually structured starting from the middle of the XVII century following the path traced by William Harvey in light of Galileo's thought.

Evaluation of the Automated Blood Bank Systems Galileo NEO and QWALYS-3 for ABO-RhD Typing and Antibody Screening / 대한수혈학회지

BACKGROUND: An automation system for ABO-RhD typing and antibody screening has been developed and its use is increasing. We compared the results of ABO-RhD typing and antibody screening tests using the manual (ABO-RhD typing) or semiautomated (antibody screening) method and with the automation instruments Galileo NEO (Immucor Gamma, Norcoss, USA) and QWALYS-3 (DIAGAST, Loos Cedex, France). METHODS: A total of 332 blood samples were tested for ABO-RhD typing in comparison with routine manual tests, and 236 samples for antibody screening in comparison with DS-Screening II (Bio-Rad Laboratories, 1785 Cressier FR, Switzerland). We evaluated the performance of Galileo NEO and QWALYS-3 in terms of concordance, carryover, and sensitivity test for ABO-RhD typing and antibody screening. RESULTS: The concordance rates of ABO-RhD typing results between the manual methods and the two instruments were 99.4% for Galileo NEO and 99.1% for QWALYS-3, respectively. On antibody screening tests, a concordance rate of 97.9% was observed between the semiautomated method and Galileo NEO or QWALYS-3, because of discordance in five specimens. The carryover was not observed for ABO-RhD typing and antibody screening. The overall sensitivity of the two automation instruments appears to be parallel with that of DS-Screening II except for anti-E. CONCLUSION: The Galileo NEO and QWALYS-3 system showed good performance, it can be used with confidence for routine pre-transfusion testing in the blood bank.

Evaluation of an Automated Solid-phase Cell Adherence Assay in the Galileo System (Immucor) for Routine Pretransfusion Tests / 대한수혈학회지

BACKGROUND: In spite of a trend of automation for conducting most clinical laboratory tests, many blood banks are still dependent on manual tests. The aim of this study was to evaluate a full automation system called the Galileo (Immucor, USA) for conducting pretransfusion tests. METHODS: From August to October in 2009, a total of 3,002 cases of ABO-RhD typing and 1698 cases of antibody screening were compared between using manual tests and the Galileo system at Seoul National University Hospital, Seoul, Korea. For the manual tests, we used the slide method for ABO-RhD typing and the anti-human immunoglobulin treated microplate method for antibody screening. The Galileo system used the microplate method for ABO-RhD typing and the solid-phase red cell adherence (SPRCA) method for antibody screening. We calculated the overall concordance rate and the false positive or negative rates regarding the manual method as a standard test and the Galileo system as a comparative test. RESULTS: When comparing 3,002 cases of ABO-RhD typing, 52 cases (1.7%) were retested. A discrepancy between the two tests remained in 17 cases (0.6%) after repetition, which led to a concordance rate of 99.4% (2,985/3,002). On the comparison of 1,698 cases of antibody screening, 54 cases (3.2%) were retested. A discrepancy between the two tests remained for 30 cases (1.8%) and the concordance rate was 98.2% (1,615/1,698). Among the 20 false negative cases (1.2%), nine were thought to be cold antibodies with no cases of confirmed warm antibody. CONCLUSION: The automated Galileo system and the preexisting manual tests showed very good concordance for ABO-RhD typing and antibody screening. The Galileo system can be used with confidence for routine pretransfusion tests.

William Harvey y los inicios de la ciencia médica moderna / William Harvey and the beginnings of modern medical science

El Renacimiento no hizo más que preparar el terreno para el surgir de la ciencia médica moderna. Ésta nació, de hecho, en la época posrenacentista y comenzó a afianzarse a mediados del siglo XVII por obra de físicos, fisiólogos y biólogos, que eran discípulos directos o indirectos de Galileo. El descubrimiento de la circulación de la sangre por Harvey se considera hoy día como el único adelanto en fisiología de principios del siglo XVII, comparable a los avances contemporáneos de las ciencias físicas. La historia de esta hazaña podría escribirse fácilmente desde el punto de vista del avance progresivo del conocimiento. En sus investigaciones, Harvey se refería a experimentos auténticos, no imaginados. y aducía irrefutables argumentos cuantitativos. Se ha afirmado con justicia que su descubrimiento de la circulación sanguínea fue la primera explicación adecuada de un proceso orgánico y el punto de partida del camino hacia la fisiología experimental. Sin embargo, la segunda monografía del sabio de Folkestone acerca de la generación de los animales, publicada en 1651, mientras que en algunos pasajes da la impresión de corresponder al razonamiento científico moderno, muestra en otros pasajes aseveraciones confusas, vagas y caprichosas, rescoldo de la era precientífica de la que el autor no había salido por completo. Puede aseverarse, por tanto, que la ciencia médica moderna no surgió de manera subitánea y global, sino que se estructuró gradualmente desde mediados del siglo XVII siguiendo la senda trazada por William Harvey a la luz del pensamiento de Galileo.

Modern medical science was born in the post Renaissance age and began to consolidate towards the middle of the XVII century thanks to physicists, physiologists, and biologists, most of whom were direct or indirect pupils, of Galilei. The discovery of blood circulation by Harvey is now considered the only progress in physiology at the beginning of the XVII century, comparable to the current advances seen in physical sciences. The history of this achievement could be written from the view point of the progressive advance in knowledge. In his experiments, Harvey referred to the authentic, not the imaginary experiments, and put forward irrefutable quantitative arguments. We can therefore claim that his discovery of blood circulation was the first proper explanation of an organic process and the starting point leading to experimental physiology. Nevertheless, the second monograph of the english researcher, dealing with the generation of animals, published in 1651, has some passages that correspond to modern scientific reasoning yet in others he includes confused, vague and capricious assertions compatible with the prescientific era that the author was not able to escape completely. In conclusion, it seems justified to assert that modern medical science did not all rise suddenly, but was gradually structured starting from the middle of the XVII century following the path traced by William Harvey in light of Galilei's thought.
