Historical aspect of transfusion medicinetashagarwal
Transfusion medicine has evolved greatly over centuries from early attempts at blood transfusions in the 15th century that proved fatal, to modern safe practices. Some key developments include the first successful animal-animal transfusion in 1665, first human-human transfusion in 1818, discovery of blood groups in 1901 which aided compatibility testing, development of anticoagulants and storage techniques in the early 20th century, establishment of the first blood bank in 1936, and advances in screening and testing that have made transfusions much safer procedures over the past few decades.
Blood banking has evolved significantly over centuries. Early practices included drinking blood for health benefits. The first recorded transfusion was in 1492 but resulted in deaths. Successful animal-to-animal transfusions were performed in the 1600s. Landsteiner discovered the three main blood groups in 1900, greatly advancing safety. During World Wars I and II, innovations like citrate preservation and plastic bags established blood as a transfusion resource. Today, components like plasma and cryoprecipitate are extracted to treat specific conditions. National policies now regulate blood banking in India to ensure safety and availability.
The summary is as follows:
1. The first documented blood transfusion was performed in 1667 by Dr. Jean-Baptiste Denys, who transfused blood from a sheep into a 15-year-old boy.
2. Karl Landsteiner discovered the three main blood groups (A, B, and O) in 1900, laying the foundation for safe transfusion by matching donor and recipient blood.
3. The development of plastic blood bags and blood component separation in the 1950s allowed for longer storage and more targeted transfusion of specific blood products.

The document summarizes the history and discoveries of the lymphatic system from ancient times to the 17th century. It describes how Hippocrates first mentioned lymph nodes, while Herophilos incorrectly believed lymph vessels drained into the liver. Galen further described lacteals and lymph nodes through animal dissections. Later discoveries identified the thoracic duct and proved lacteals do not terminate in the liver. The 17th century saw acceptance of blood recirculation and naming of lymphatic vessels. Galen's ideas of blood production were eventually disproven.
The document discusses the anatomical framework that classifies humans as members of the animal kingdom and mammalian class. It provides an overview of human anatomy and evolutionary traits shared with other mammals. The history of human anatomy is explored, from early Egyptian and Greek understandings, through the influential work of Galen and Vesalius, to modern reference texts like Gray's Anatomy.
This document provides a historical perspective on tetralogy of Fallot, beginning in the 17th century with early descriptions of heart anatomy and circulation. It then outlines key figures from the 18th-19th centuries who further described abnormalities and malformations. In the 20th century, major advances included the first repair surgeries using cardiopulmonary bypass and controlled cross-circulation. Surgical techniques improved repair outcomes for tetralogy of Fallot. Associated genetic syndromes were also described. Echocardiography enhanced non-invasive diagnosis of congenital heart defects including tetralogy of Fallot.
Early Greek physicians like Hippocrates believed illness had physical causes and rejected superstitions, basing treatments on observations. Later, Galen and Da Vinci advanced anatomy through dissections of animals and humans, though Galen mistakenly assumed human and animal anatomy were identical. Andreas Vesalius was the first to accurately document human anatomy through dissecting criminals with papal permission. As medical schools opened, anatomists relied on executed criminals for cadavers due to beliefs that dissection prevented resurrection. William Harvey advanced circulation studies by dissecting family members. Some later anatomists resorted to grave robbing due to corpse shortages.

1) Galen discovered that the kidneys are the source of urine.
2) William Harvey discovered that blood circulates through organs including the kidneys, driven by heart contractions.
3) Marcello Malpighi discovered the fine structure of the kidney providing insight into its function using early microscopes.
4) Richard Bright was the first to describe clinical manifestations of kidney disease known as Bright's disease.
Kidney transplantation from myth to reality , ajman meeting 2013 mayAyman Seddik
This document discusses the history of organ transplantation from ancient myths to modern practice. It begins with stories from ancient civilizations featuring organs exchanged between humans and animals. Early experiments in the 1900s involved the first animal-to-animal and human kidney transplants. Major advances included defining brain death criteria, developing immunosuppressive drugs like cyclosporine, and establishing criteria for living and deceased donors. Today kidney transplantation has better long-term survival outcomes than dialysis and is an established treatment for end-stage renal disease.
This document discusses the history and types of stem cells and their applications in regenerative medicine. It defines stem cells as unspecialized cells that can differentiate into other cell types and self-renew. It describes the different types of stem cells based on their potency, from totipotent stem cells found in early embryos to unipotent adult stem cells. The document outlines milestones in the development of organ and cell transplantation, from early blood transfusions to modern bone marrow transplantation. It discusses the potential of stem cells to treat diseases and conditions like Parkinson's, Alzheimer's, spinal cord injury, and diabetes.
The document discusses the history of understanding of blood circulation in various medical traditions. It provides a table listing important figures from Egypt, Greece, Rome and the medieval era who contributed insights into circulation. While many proposed pulmonary and hepatic circulation, William Harvey in 1628 was the first to fully explain the complete systemic circulation. Ayurvedic texts like Charak Samhita and Sushrut Samhita contain descriptions of rasavah srotas and circulation of nutrients through the body but were not included in the table.
The history of resuscitation has evolved over thousands of years as techniques were developed to address airway, breathing, and circulation issues in attempts to reverse sudden death. Early civilizations used techniques like inversion, chest pounding, and smoke inhalation. The 1700s saw the establishment of early resuscitation societies in Europe that standardized approaches including warming, positioning, and manual ventilation. Major advances included the development of tracheostomy tubes, laryngoscopy, mouth-to-mouth breathing, external chest compressions, and defibrillation. By the 1960s cardiopulmonary resuscitation was standardized through the American Heart Association guidelines, combining techniques into the ABC approach still used today. Intensive care units also emerged in
Dr. Harvey Cushing was a pioneering American neurosurgeon who made many important discoveries, including describing Cushing disease and the Cushing reflex. He had a distinguished career as a surgeon, researcher, author, and teacher, making major contributions to the fields of neurology and neurosurgery.
This document provides a history of discoveries related to DNA from 1859 to 1950. Some of the key events and discoveries discussed include:
- In 1859, Charles Darwin published On the Origin of Species, introducing the theory of evolution by natural selection.
- In 1866, Gregor Mendel discovered the basic principles of genetics by studying inherited traits in pea plants and coined the terms "dominant" and "recessive".
- In 1869, Friedrich Miescher isolated a substance he called "nuclein" from white blood cells, which we now know as deoxyribonucleic acid (DNA).
- In 1900, Mendel's work was rediscovered and his theories gained acceptance, laying the
Kidney transplantation from myth to reality , ajman meeting 2013 mayAyman Seddik
This document discusses the history of organ transplantation from ancient myths to modern practices. It covers early experimental transplant attempts in the 1900s-1950s using animal organs that failed due to rejection. The first successful kidney transplant was performed in 1954 between identical twins. Cyclosporine revolutionized transplantation in the 1980s by reducing rejection rates and allowing non-renal organ transplants. Now transplantation offers superior long-term survival compared to dialysis and over 800,000 transplants have been performed worldwide with records of 45 years for kidney grafts.
High School World History Lecture dealing with the Scientific Revolution during the Age of Enlightenment. Galileo, Newton, Bacon, Descartes, Jenner etc.
The history of anatomy extends from early examinations of sacrificial victims in ancient Egypt to modern scientific analyses. Over time, understanding of organ and body structure functions has continually developed. In ancient Egypt and Greece, early anatomists like Alcmaeon began the first scientific dissections and discoveries about structures like the brain, heart, and blood vessels. Galen's 2nd century AD dissections of apes and pigs informed his influential works on anatomy, though some theories like blood flow were later found to be incorrect. Anatomical study declined in the Middle Ages but resumed with innovations like Vesalius' cadaver dissections in the 16th century and Harvey's discovery of blood circulation. Modern anatomy applies new technologies to further understand structure
Prometheus was punished by Zeus for stealing fire and giving it to humans. He was chained to a rock and each day an eagle would eat his regenerating liver as punishment. The liver's vascular anatomy was extensively studied in the 17th century and its lobes were defined in the late 19th century. Successful elective liver resections were first performed in the late 19th century using principles of hemostasis and regeneration established in the prior decades. The concept of inflow control was a major advancement, described by James Pringle in the early 20th century. While mortality rates were initially high, techniques improved and the first cancer resection was performed in 1949. The liver was described as a "hostile" organ due to its
Today marks the death of the Austrian zoologist Konrad Lorenz in 1903. He was the founder of modern ethnology (the study of animal behaviour by means of comparative zoological methods). He was known affectionately by his pupils as the "father of the grey geese" which he studied. His ideas revealed how behavioural patterns may be traced to an evolutionary past, and he was also known for his work on the roots of aggression. He shared the 1973 Nobel Prize for Physiology and Medicine, for developing a unified, evolutionary theory of animal and human behaviour.
Historical article -hirudo medicinalis--ancient origins of, and trends in the...Younis I Munshi
This document summarizes the history of using medicinal leeches (Hirudo medicinalis) for medical purposes. It discusses how leech use dates back to ancient Egypt and was also used in ancient China, India, Greece, and Rome. Leech use became widespread in Europe between 1825-1850, but then fell out of favor. Recently leeches have seen a resurgence being used in microsurgery to aid in tissue transfers and replantation. The document outlines key people and periods in the history of leech use from ancient times to the present day.
Charles Drew was a medical researcher born in 1904 who improved blood transfusion processes. He found that using blood plasma alone instead of whole blood for transfusions increased how long blood could be stored and lowered costs. Drew also founded the American Red Cross and helped advance blood banking through his research.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

Blood Transfusion Science
2. MYTHS MYSTICS AND RITUALS
• In the bible: leviticus 17:11
The life of the flesh is in the blood
The circa 100BC (Chinese
Neiching)
The blood contains the soul
3. MYSTICS RITUALS AND MYTHS
BLOOD LETTING
The Romans
Drank gladiators blood to cure epilepsy
Taurobolium (blood bath for spiritual restoration) the pit or
fossa sanguinis
Egyptians
Blood baths for recuperation
American Indians
Blood Letting as a source of self-punishment
4. MYTHS MYSTICS AND RITUALS
Myths
The legend of Medea and Aeson taken from Ovid’s
Metamorphoses and quoted in Bulfinch’s Mythology
Jason asked medea to take afew years of his life
and add to his father’s (Aeson) But what does
Medea do?
Pope innocent VIII of 1492 and the Three
10year old boys
5. Ancient beliefs
Early Greeks held that blood was formed in the heart,
flowed through veins and consumed by the body
Arteries were only transporters of air
Erasistratos (circa 270 BC) believed that the heart was
a pump! That was way beyond his time…….!
Galen advised that the drinking of Dog’s blood cured
epilepsy!
Egyyptians believed it to be a cure for elephantiasis!
The Vikings reportedly drank whale and seal blood as
cure for scurvy and epilepsy!
6. Blood Circulation
Errors that masked the discovery of circulation
Arteries contained only air and no blood
The septum between the heart chambers was perforated
Veins carried blood away from the heart
Sushtra in the 6th century BCE showed knowledge of circulation
Aristotle in 350 BCE described the heart as the central organ of
the heart
Herophilos and Erasitratus showed that when cut during life
they bleed.
Ibu Al Nafis accurately described pulmonary blood circulation in
1242
7. Discovery of the blood circulation
Galen (131-201AD) discovered the blood also flowed
in the arteries
And we still believed that the arteries and veins were
dead ends for the next 1400years!
Well until 1628 when Harvey discovers the
circulation!
8. Blood Cells
Jan Swammerdam (1658) described the red blood
cells, Anton Van Leewenhoek (1674) also did.
Max Shultze described the platelets while in
addition, Giulio Bizzozero showed blood clumps at
site.
Paul Ehrlich formulated blood cell staining dyes
(Nobel prize!)
1959 Max Perutz demonstrated the structure of Hb
9. Circulatory system
Galen also Identified arterial and venous blood
Ibn al-Nafis, Michael Servetus and Realdo Colombo all
showed that blood circulated via both arteries and veinns
William Harvey described the venous valves and
their functions
Marcello malpighi discovered the capillary system
Gaspare Aselli discovered the lymphatic circulation
10.
11. The circulation system
The discovery caused scientists to experiment with
vascular infusions!
In 1642 George von Wahrendorff injected wine
1656 Christopher Wren and Robert Boyle injected
opium and other drugs
Richard Lower then took it a further step…….
12. First animal Transfusion
Lower transfused dogs by inserting a quail in the
carotid artery of one dog and the jugular vein of the
other.
He reports that the transfused dog would jump off
the table as if nothing had happened!
KSPCA!!!!
13. Human transfusions
Pope Giovanni Cibo between 1490 and 1492 three
young boys either were transfused or the pope drank
their blood
In 1615 Andreas Libavius imagined and wrote about
blood transfusions but never performed any.
In 1628 harveys work on the transfusion practice
were published.
14. Human Transfusion
Presently these inevitably turned to Man and on
23rd November 1667
Lower and Edmund king performed this on Mr.
Arthur Coga using sheep blood! Using sheep
blood!!! For 20 shillings!!!!
Oh! But 6 months earlier Jean-Baptiste Dennis had
done the same after studying Lower’s experiments
for a month!!!
So the 1st animal to Human transfusion was on June
15th 1667!!
15. Why Animal blood
In those days. Moods were associated with blood!
Melancholy, Envy, Sadness, Calmness, Rowdiness!!
• And therefore animal blood did not have these impurities!!
• Sheep blood transfused to a 15yr old boy
• The boy had been bled 20times! Hence profound anaemia.
When transfused there were no adverse effects!!
16. The tussle
The French and the Britons tussled over who
performed the 1st human transfusion!
Dennis’s letter of successful transfusion was re-
serialized by the British publisher!
17. The fourth patient
Mr. Anthony du Mauroy! A maniac who beat his wife
incessantly!
The first transfusion had no effect and a second one 2
days latter!
Classic transfusion reaction results
After 2 months du Mauroy again became maniacal and
the wife requested another transfusion therapy
Madame du Mauroy insisted until Dennis agreed
Before the transfusion was done du Mauroy died!!
18. Malpractice
Some Paris physicians were unhappy with the
transfusions
A malpractice suit
Madame du Mauroy the extortionist!!
The Charge of arsenic poisoning
The Verdict!!
19. The Verdict
A blow to further transfusion research; judgment
handed down at the Chatelet in Paris on April 17,
1668, The court stipulated “that for the future no
Transfusion should be made upon any Human Body
but by the approbation of the Physicians of the
Parisian Faculty.
Research went into decline, and within 10 years it
was prohibited in both France and England.
In 1679 the Pope also joined in advocating a ban
Blood at the time was considered only for restoration
of mental health, or for youth and vigor to the ages
20. 150 years later
James Blundell (1790-1877) an obstetrician stated
that lives that would otherwise be saved by
transfusion were being lost!
Blundell introduced transfusion by the syringe and
stated that only human blood for Humans!
Out of 10 transfusions 5 were successful while in five
the patients died.
Most were on the throes of death
21. Human to Human Transfusion
The first 1818 with the aid of dr. Henry Crine Noyes
Dr. Blundell also devised implements used for
transfusion including
The impeller
The gravitator
23. Early transfusions
Blundell confined his cases to 1st class cases only
Challenges like coagulation were prevalent
The amount of blood given was not measurable
Defibrinated blood was used to circumvent the
problem of coagulation
It was difficult to detect reactions as these cases were
terminal
24. Dr John Henry Leacock showed that blood was safer
when transfused only within Species not across.
It was the works of Dr. Henry that inspired Blundell
to continue with transfusion in extreme cases of
Haemorrhage
25. Due to the frustration occasioned by the failure of
blood transfusions, physicians resorted to bizarre
practices.
These included
Transfusion of
Cow milk
Goat
And Human Milk.
26. Further medical catastrophe was averted by the
discovery of saline as replacement for plasma.
Saline was viewed as a substitute for blood
transfusion
This volume replacement diverted attention from
blood transfusion for sometime until interest was
rekindled at the turn of the 20th century
27. The 20th century
In 1901 Karl Landsteiner discovered the three blood
groups and named them A, B and C.
Landsteiner noticed that sera from some individuals
agglutinated red cells of others.
In 1902 Decarstello and Sturli found a fourth blood
group! These early scientists also contributed to
forensic science by designing a method for blood
typing using dried blood
28. Jan Jansky and Dr. Moss also found these blood groups
independently in Czechoslovakia and the United States.
It was not until 1907 when the impact of the
discoveries was felt
Dr. Richard Weil started systematic pre-transfusion
grouping in 1907 in New York.
Jansky and Moss gave roman numerals to Identify the
groups this confused and complicated the discoveries
and were to be abandoned in 1927 after the American
society of Immunologists adopted Landsteiner’s
method of nomenclature.
Indeed the blood group C of Landsteiner was renamed
O
29. Although Ludvig Hektoen and Reuben Ottenberg
exhaustively advocated for crossmatch and showed
the absolute value in transfusion, even now some
professionals still doubt the value of crossmatching.
Dr. Felix Bernstein in 1924 proved the theory of
blood group inheritance conclusively.
Felix’s pattern was however manipulated in
Germany in world war I & II and as a tool of
segregation in the US
30. Other contributions
The transfer of blood from one individual to another
proved oft difficult. Due to clotting of blood
Direct anastomosis was possible by the discovery of
Carrel (end to end vascular anastomosis with triple
threaded suture material.
Crile introduced a metal tube to facilitate suture
insertion
Bernheim introduced a two piece cannular
Yet in all these there was still danger of Collapse of the
donor and death
31. For the first time in Ottenberg’s transfusions, it was
possible to Identify transfusion reactions.
He also showed the Universality of blood group O
donors
32. Further discoveries
Between 1927 and 1947 M, N and P systems were
described.
In 1939 Levine and Stetson showed that blood group O
transfused to a blood group O patient resulted in a still
birth when the child was the fathers blood group.
Landsteiner and Weiner showed that an anti-body
harvested from a rabbit sensitized with Rhesus monkey
blood agglutinated 85% of human red cells and not 15%.
These results correlated with those of Levine and Stetson
The Rh system was discovered thus
33. The use of nomenclature has evolved to date from
Landsteiner to The International Society of Blood
Transfusion system in Current use.
Notable discoveries also included the introduction of Rh
Immune Globulin.
The antiglobulin test was discovered by Carlo Moreschi
in 1908, rediscovered by Dr Robin Coombs, Rob Race
and Arthur Mourant in 1945
34. Anticoagulants blood Banking and component
therapy
Citrates were in use at 5% concentrations which were
toxic to Humans.
Notable contributions from Dr. Weil, Dr. Lewisohn,
Rous & Turner, Loutit & Mollison all were involved
in the design of anticoagulants that proved
successful in the world war two.
35. The first transfusion service was organized by the
republican army during the Spanish civil war of 1936-
1939
About 9000litres in citrate-dextrose anticoagulant was
collected
Fantus, developed the concept of a blood bank at the
same time in Chicago.
A regional concept of Blood banking was already in
existence in Britain at the beginning of the 2nd world war
In America The American Red cross Organized the
largest National program for blood banking
36. At this time the needles used were all steel, the blood
bottles were made of glass and were washable,
sterilized and reusable.
Plasma fractionation was also developed at this time
The dawn of a golden age of patient care with specific
products was upon us!!
But woe unto us! The HIV virus hit us like a bomb!
37. Transfusion in the current
During the golden age of transfusion, nearly all
procedures were done with blood transfusion
The discovery of disease in donated blood dealt a
huge blow to this.
HIV, HCV, HBV, Syphilis among others have cast a
huge shadow on blood transfusion.
The availability of blood has also been a major
constraint in transfusion
38. Today
The public today is aware of blood safety and will
demand zero risk for transfusion
This has led to increased surveillance of blood and
diseases, Hemovigilance and a marked increase in
the tools of detection of disease.
DNA testing and other sophisticated methods have
also been used.
