Topic: Group za Damu

Wadau naomba msaada wenu,kwenye ma group ya Damu kuna group la o- (O negative) huyu anaweza akamuongezea mtu mwenye damu group gani?
Nasumbuka sana na swali hili tafadhali anayejua naomba anijulishe pamoja na ma group mengine.

Blood Groups, Blood Typing and Blood Transfusions


Have you played the new version of the popular Blood Typing Game?


The discovery of blood groups

Experiments with blood transfusions, the transfer of blood or blood components into a person's blood stream, have been carried out for hundreds of years. Many patients have died and it was not until 1901, when the Austrian Karl Landsteiner discovered human blood groups, that blood transfusions became safer.
Mixing blood from two individuals can lead to blood clumping or agglutination. The clumped red cells can crack and cause toxic reactions. This can have fatal consequences. Karl Landsteiner discovered that blood clumping was an immunological reaction which occurs when the receiver of a blood transfusion has antibodies against the donor blood cells.

Karl Landsteiner's work made it possible to determine blood groups and thus paved the way for blood transfusions to be carried out safely. For this discovery he was awarded the Nobel Prize in Physiology or Medicine in 1930.

What is blood made up of?

An adult human has about 4–6 liters of blood circulating in the body. Among other things, blood transports oxygen to various parts of the body.
Blood consists of several types of cells floating around in a fluid called plasma.

The red blood cells contain hemoglobin, a protein that binds oxygen. Red blood cells transport oxygen to, and remove carbon dioxide from, the body tissues.

The white blood cells fight infection.

The platelets help the blood to clot, if you get a wound for example.

The plasma contains salts and various kinds of proteins.


What are the different blood groups?

The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.
There are more than 20 genetically determined blood group systems known today, but the AB0 and Rh systems are the most important ones used for blood transfusions. Not all blood groups are compatible with each other. Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals.
Nobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 blood group (in 1901) and Rh blood group (in 1937).

AB0 blood grouping system

According to the AB0 blood group system there are four different kinds of blood groups: A, B, AB or 0 (null).

	Blood group A If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma.
	Blood group B If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma.
	Blood group AB If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma.
	Blood group 0 If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.

Rh factor blood grouping system

Many people also have a so called Rh factor on the red blood cell's surface. This is also an antigen and those who have it are called Rh⁺. Those who haven't are called Rh^-. A person with Rh^- blood does not have Rh antibodies naturally in the blood plasma (as one can have A or B antibodies, for instance). But a person with Rh^-blood can develop Rh antibodies in the blood plasma if he or she receives blood from a person with Rh⁺ blood, whose Rh antigens can trigger the production of Rh antibodies. A person with Rh⁺ blood can receive blood from a person with Rh^- blood without any problems.


Blood group notation

According to above blood grouping systems, you can belong to either of following 8 blood groups:

A Rh+	B Rh+	AB Rh+	0 Rh+
A Rh-	B Rh-	AB Rh-	0 Rh-

Do you know which blood group you belong to?

Blood typing – how do you find out to which blood group someone belongs?


1.
You mix the blood with three different reagents including either of the three different antibodies, A, B or Rh antibodies.
2.
Then you take a look at what has happened. In which mixtures has agglutination occurred? The agglutination indicates that the blood has reacted with a certain antibody and therefore is not compatible with blood containing that kind of antibody. If the blood does not agglutinate, it indicates that the blood does not have the antigens binding the special antibody in the reagent.

3.
If you know which antigens are in the person's blood, it's easy to figure out which blood group he or she belongs to!

A person with A+ blood receives B+ blood. The B antibodies (yellow) in the A+ blood attack the foreign red blood cells by binding to them. The B antibodies in the A+ blood bind the antigens in the B+ blood and agglutination occurs. This is dangerous because the agglutinated red blood cells break after a while and their contents leak out and become toxic.

What happens when blood clumps or agglutinates?

For a blood transfusion to be successful, AB0 and Rh blood groups must be compatible between the donor blood and the patient blood. If they are not, the red blood cells from the donated blood will clump or agglutinate. The agglutinated red cells can clog blood vessels and stop the circulation of the blood to various parts of the body. The agglutinated red blood cells also crack and its contents leak out in the body. The red blood cells contain hemoglobin which becomes toxic when outside the cell. This can have fatal consequences for the patient.

The A antigen and the A antibodies can bind to each other in the same way that the B antigens can bind to the B antibodies. This is what would happen if, for instance, a B blood person receives blood from an A blood person. The red blood cells will be linked together, like bunches of grapes, by the antibodies. As mentioned earlier, this clumping could lead to death.
Blood transfusions – who can receive blood from whom?

Of course you can always give A blood to persons with blood group A, B blood to a person with blood group B and so on. But in some cases you can receive blood with another type of blood group, or donate blood to a person with another kind of blood group.

The transfusion will work if a person who is going to receive blood has a blood group that doesn't have any antibodies against the donor blood's antigens. But if a person who is going to receive blood has antibodies matching the donor blood's antigens, the red blood cells in thedonated blood will clump.

People with blood group 0 Rh - are called "universal donors" and people with blood group AB Rh+ are called "universal receivers." Rh+ blood can never be given to someone with Rh - blood, but the other way around works. For example, 0 Rh+ blood can not be given to someone with the blood type AB Rh -.

Blood Group	Antigens	Antibodies	Can give blood to	Can receive blood from
AB Rh+	A, B and Rh	None	AB Rh+	AB Rh+ AB Rh - A Rh+ A Rh - B Rh+ B Rh - 0 Rh+ 0 Rh -

According to a Japanese institute that does research on blood types, there are certain personality traits that seem to match up with certain blood types. How do you rate?

TYPE O	You want to be a leader, and when you see something you want, you keep striving until you achieve your goal. You are a trend-setter, loyal, passionate, and self-confident. Your weaknesses include vanity and jealously and a tendency to be too competitive.
TYPE A	You like harmony, peace and organization. You work well with others, and are sensitive, patient and affectionate. Among your weaknesses are stubbornness and an inability to relax.
TYPE B	You're a rugged individualist, who's straightforward and likes to do things your own way. Creative and flexible, you adapt easily to any situation. But your insistence on being independent can sometimes go too far and become a weakness.
TYPE AB	Cool and controlled, you're generally well liked and always put people at ease. You're a natural entertainer who's tactful and fair. But you're standoffish, blunt, and have difficulty making decisions.

Rh -. Mara nyingi sana mwenye O Rh- anaweza kuwekewa Rh+ blood akaishi kwani mwili utajifunza kuanza kutengeneza Rh+.

pia kuna tabia nyingine ya O Rh ambayo ni mama mwenye rh- akitokea kupata ujauzito wa mtoto mwenye rh+ basi mtoto huyu atazaliwa kwani mwili wa mama utajitengenezea uwezekano wa kuztengeneza rh+. Lakin sas mama huyu hataweza tena kupata mtoto mwenye rh- hivyo kila akipata ujauzito mimba huaribika baada ya muda.
