aid the physician in the diagnosis, study and treatment of disease and in the promotion of health in general.
Medical Technology
Oldest preserved Egyptian compilation of medical texts
Ebers Papyrus
Contains chapters on contraception, pregnancy, eye and skin problems, surgery, burns and intestinal diseases and parasites
Ebers Papyrus
describes the treatment of hookworm disease and infection transmissible to human
Ebers Papyrus
first medical technologist
Vivian Herrick
medical technologist who traced the beginning of medical technology when intestinal parasite such as Taenia and Ascaris were first identified
Vivian Herrick
Father of Medicine
Hippocrates
Advocated the use of mind and senses as
diagnostic tools
Hippocrates
He described four humors or body fluids in the
human body
Hippocrates
oldest lab procedure
Urinalysis
poured urine on ground when it attracts insects = patient diagnosed with boils - large pimples
Greeks
What are the four humors?
A. blood
B. phlegm
C. yellow bile
D. black bile
based upon the observation of Blood as drawn in a glass container and left undisturbed for about an hour.
four humours
dark clot at the bottom
Black bile
Above the clot is a layer of RBC
Blood
Above is a whitish layer of WBC = now called the buffy coat)
Phlegm
The top layer is clear yellow serum
Yellow Bile
Made the first description of hematuria
Rufus of Ephesus
presence of blood in the urine. Due to inability of the kidneys to filter blood
hematuria
diagnosis by visual examination of urine. (water casting method-flask)
Uroscopy
symbol of medieval medicine
Urine flask
Detailed concepts of urine formation, urine sediments and urine characteristics in relation to diseases
Kitab al Baul (Body of Urine)
Formulated rules for the use of urine in patients’ diagnosis
Isaac Judeus
One of the founders of the origins of nephrology - study of the kidney
Isaac Judeus
Failure of physicians to examine patient’s urine was punishable by public beatings
Jerusalem Code of 1090
invented microscope (1590s)
Zaccharias Janssen and his father Hans
Believed that MT began from this period as supported by the fact that urinalysis was a fad.
Ruth Williams
Made the “scientific observation” that the urine of certain individuals attracted to ants - such urine have a sweetish taste. (diabetic)
Hindu Doctors
Believed that MT started when a prominent Italian doctor at the University of Bologna employed Alessandra Gillani to perform different task in the lab
Anne Fagelson (14th Century)
used in staining microorganisms (able to identify microorganisms according to their shape and size)
aniline dyes
First one to saw bacteria and classified them according to shapes. Described blood cells, muscle fibers, spermatozoa and protozoa
Anton van Leeuwenhoek (1632)
Father of Microbiology
Anton van Leeuwenhoek (1632)
Greatest of the early microscopists.
Blood of patients with plagues contained “worms”
Athanasius Kircher (1646)
contributions to embryology and anatomy made him known as the “Founding father of modern Anatomic Pathology”
Marcello Malpighi
Introduced the gravimetric analysis of urine by weighing a number of 24-hr urine specimens against water
Jean Baptiste van Helmont
Investigated and showed that blood transfusion from one animal to another is possible
Richard Lower (1631-1691)
Observed that proteins in the urine precipitated when boiled with acetic acid
Frederick Dekkers (1694)
the presence of protein in the urine (kidney disease)
proteinuria
Discovered that plasma could be separated from blood cells when blood clots
William Hewson (1739-1774)
could be precipitated from the plasma upon application of temperature higher than 50°C
Coagulable lymph
Coagulable lymph
fibrinogen
recognized as the Father of Microscopic Pathology
Rudolf Virchow (1847)
Founder of Archives (collection of records) of Pathology in Berlin

- Vaccine for a bacterium Bacillus anthracis
anthrax vaccine
One of the main founders of modern bacteriology
Heinrich Hermann Robert Koch
4 generalize principles linking specific microorganisms to specific diseases that remain today as the “gold standard” in medical microbiology
Koch’s postulate
