ABO blood group
ABO blood group: The major human blood
group system. The ABO type of a person depends upon the presence or
absence of two genes, A and B. These genes determine the
configuration of the red blood cell surface.
A person can be A, B, AB, or O. If a person has two A genes, their
red blood cells are type A. If a person has two B genes, their red
cells are type B. If the person has one A and one B gene, their red
cells are type AB. If the person has neither the A nor B gene, they
are type O. The situation with antibodies in blood plasma is
the opposite of the red cell antigen types. Someone with type A red
cells has anti-B antibodies (directed against type B red cells) in
their blood. Someone with type B red cells has anti-A antibodies in
plasma. Someone who is type O has both anti-A and anti-B antibodies
in plasma. And someone who is type AB has neither anti-A nor anti-B
antibodies in plasma. It is most important to determine the
ABO status of
both donor and recipient in transplants and transfusions. ABO
incompatability in such procedures can be a disaster. The
recorded blood transfusion may have taken place in 1492 when Pope
Innocent VIII, laying in a coma, was given the blood of 3 young men.
Blood typing and crossmatching was not done. The pope died, as did
the 3 donors.
In 1901 a Viennese pathologist named Karl Landsteiner (1868-1943)
published an aricle entitled "On Agglutination Phenomena of Normal
Human Blood," in which he observed that, when blood was transfused
from one human to another, the body often clumped the transfused
blood cells and rejected the transfusion, sometimes going in shock.
In 1909 Landsteiner classified red blood cells into types A, B, AB
and O and showed that the body rejects transfusions of a different
blood type. After moving to the Rockefeller Institute in New York,
Landsteiner received the Nobel Prize in 1930 for his pioneering
research in immunology and blood grouping.
ABO hemolytic disease of the newborn
erythroblastosis fetalis resulting from maternal-fetal incompatibility with respect to an antigen of the ABO blood group; the fetus possesses A or B antigen (or both), that is lacking in the mother, and the mother produces immune antibody, that causes hemolysis of fetal erythrocytes.
Electromagnetic unit of resistance equal to 10−9 ohm.
In a direction away from the mouth; opposite of orad.
The expulsion of an embryo or fetus before it is viable.
The removal of the products of conception prematurely.
To arrest a disease in its earliest stages.
To arrest any action or process before its normal completion.
See Also: miscarry
a loss of the systolic beat in the radial pulse through weakness of the ventricular contraction.
An agent that produces abortion.
Alternate names: aborticide, abortient, abortigenic, abortive3
Abortion: In medicine, an abortion is the
premature exit of the products of
conception (the fetus, fetal membranes, and placenta) from the
uterus. It is the loss of a pregnancy and does not refer to why that
pregancy was lost. A spontaneous abortion is the same as
a miscarriage. The miscarriage of 3 or more consecutive
pregnancies is termed habitual abortion.
the number of induced abortions per 1000 pregnancies that resulted in a live birth, stillbirth, or induced termination.
the number of terminations ×1000 ÷ the female population ages of between 15 and 44 years.
Abortion, habitual: The miscarriage of 3 or more
consecutive pregnancies. Recurrent abortion can be identically defined as 3 or more
miscarriages (spontaneous abortions) with no intervening pregnancies. Habitual or
recurrent abortion is a form of infertility.
Abortion, multiple: Couples who have had 2 or more
miscarriages (spontaneous abortions) have about a 5% chance that one member of the couple
is carrying a chromsome translocation responsible for the miscarriages.
Abortion, recurrent: See Abortion, habitual.
One who performs an abortion.
Not reaching completion; said of an attack of a disease subsiding before it has fully developed or completed its course.
Alternate names: rudimentary
transduction in which the genetic fragment from the donor bacterium is not integrated in the genome of the recipient bacterium, and, when the latter divides, is transmitted to only one of the daughter cells.
Any product (or all products) of an abortion.
Abbreviation for androgen binding protein.
Abbreviation for allergic bronchopulmonary aspergillosis.
Congenital absence of arms and head.
Alternate names: acephalobrachia
To wear away by mechanical action.
To scrape away part or all of the surface layer from a part.
earlier appreciation of abnormal pulmonary auscultatory signs over the distal clavicle than at the apex, suggesting apical tuberculosis.
diminished percussive resonance over the pulmonary apex in advancing tuberculosis.
