Magus Tech Chapter 62: Blood matching

Taking more than a dozen drops of blood from Gero's wound and dripping them into clean silver plates, Li Cha looked up at the nobles and said, "Next, I will take a drop of blood from each of you. Come and mix with Gero's blood. This is because there is very little blood in Gero's body now, so it is necessary to find someone who can give him a blood transfusion and inject some blood into his body to restore him to health and save him. So Each of you will take this test."

Blood transfusion?

Not only no bloodletting? Need a blood transfusion?

It really is a heresy, it really is a wizard's spell!

But this time is the time to show loyalty.

"Each of us can transfuse the prince's blood!" In the crowd, someone said this, and then many people agreed, "Wizard, if you can save Prince Gero, you can use our blood." Available."

Li Cha shook his head and said, "Not everyone can do it, only those who meet the requirements."

"Why?" someone in the crowd asked.

"The reason is very simple." Li Cha poured out a breath, "Blood and blood are not exactly the same. Generally speaking, blood is not a pure red liquid, and there are many other substances in it. If some substances are different, Blood can produce... well, toxicity, so blood can't be transfused casually."

This is Li Cha trying to explain in words that a group of people can understand. After all, the other group of people are not maids, craftsmen, and soldiers in the palace.

In the palace, no matter how complicated what Li Cha said, the maids, craftsmen, and soldiers will try to understand it hard. They can cultivate some vague scientific thinking, and then select some outstanding people from it to train and use.

So if it is in the palace, facing some ordinary soldiers and craftsmen, Li Cha will explain in detail, some blood components, explain plasma, blood cells and so on, and see the other party's reaction.

When facing the maid, he will explain more, and will say some reactions to specific antigens (agglutinogens) on the surface of red blood cells. For example, the division of ABO blood types, such as which agglutinin is in type A blood, which agglutinin is in the serum, which blood will not agglutinate, and will not cause vascular obstruction and hemolysis, etc. Even if the maid doesn't understand, it doesn't matter, there is nothing wrong with remembering first.

But now, in the face of a group of unfamiliar nobles, it is obviously not worth cultivating and using, so Li Cha is too lazy to explain the scientific knowledge in it, and it is enough to explain it in the most simple words.

But even so, everyone was still stunned, surprised at what Richard said, and then a lot of doubts arose.

"Is blood poisonous?"

"How can blood be poisonous?"

"Isn't blood blood, why are there other things?"

"Blood..."

This is a disadvantage of not explaining in detail, because without the support of a complete system, even if there is a place beyond the cognition of ordinary people, it will immediately arouse more doubts and curiosity. In this case, if you directly narrate a complete set of theories, no matter whether the other party understands it or not, it will definitely make the other party shut up.

But until now, Li Cha didn't want to waste any more time to remedy anything, and said directly: "You don't need to figure out why blood is poisonous, you just need to know that there is a reason for me to do this. If you don't want Gro to die Just do as I say, of course, if you want him to die, just pretend I didn’t say anything.”

"Amount..."

Everyone looked at each other, they couldn't calm down anymore, they finally stepped forward and started the blood test.

Suddenly, Li Cha thought of something, and asked aloud: "By the way, who among you is a close relative of Ge Luo? The immediate and collateral relatives within three generations are counted, such as brothers, sisters, cousins, etc."

During the second of silence, everyone looked at a person in the crowd.

The one who was watched by everyone was a short nobleman, trying to maintain his superficial composure, he looked at Richard and said, "I am, what's the matter?"

"Then you don't need to test your blood." Richard said, paused and said with certainty, "You have been ruled out."

"Ah, why... why?" The other party obviously didn't understand why, as a distant cousin, he became a special existence.

"Are you sure you want me to explain?"

"Uh, this..." The other party thought for a while, felt that Li Cha had really explained it, but couldn't understand it, and finally shook his head and said, "Forget it."

Li Cha said: "You are very smart."

"Amount."

Actually, Li Cha really explained it, and the other party really couldn't understand it. Because biological knowledge is involved, it is more complicated than blood type.

Due to the misleading of many film and television works on the modern earth, many people think that when someone is sick and needs a blood transfusion, they can use blood of the same type from close relatives, preferably direct relatives, children, grandchildren, and parents.

Only in this way can we show the love of father and mother, and the filial piety of sons and grandsons. What's more, in this way, one might discover the old news of the love many years ago, and then produce such gossip stories that one's own son is not his own son, and the nurse is his own daughter.

But in fact, those who dare to transfuse close relatives under real circumstances can only be said to admire their courage and pity their IQ.

Modern earth medicine has proved that blood transfusion between relatives is extremely dangerous, especially the transfusion of untreated fresh blood between immediate relatives may cause graft-versus-host disease (GVHD). Once it happens, the mortality rate is as high as 99.9%, and basically no rescue is needed.

This is because the blood is usually mixed with lymphocytes from the donor. Under normal circumstances, when a patient receives a blood transfusion, the immune organs will promptly recognize and eliminate the lymphocytes in the foreign blood that are different from their own~IndoMTL.com~ But if it is the blood of close relatives, it cannot be recognized because of the similarity in genes, and it is harmless by default. A pseudo-acquired immunodeficiency syndrome (AIDS, AIDS).

As a result, foreign lymphocytes can survive in the patient's body, proliferate in large numbers, and then attack various tissues and organs of the patient, causing the patient to have fever, rash, diarrhea, enlarged lymph glands, hemolytic anemia, etc., and eventually die.

Regarding this, Li Cha didn't want to gamble on his luck, so he tested how lucky Gro was. Rather than trying to get everything right and then end up **** it up with GVHD from a blood transfusion in a close relative, it's better not to do it in the first place.

Exhaling lightly, Li Cha looked at the silver plate.

At this time, the nobles had already finished the blood test separately, and the results were not very good. Gero's blood should be the relatively rare AB blood type. According to the statistics of modern Earth, this blood type only accounts for 7%, so Only one of those present matched.

But it is not the worst. After all, besides ABO blood type, there are more complex blood type systems, such as Rh blood type system, Hh/Bombay blood type system, sub-Mumbai blood type system, P blood type system, Midianbao blood type system, etc. .

The relatively rare Ph blood type is called panda blood, and the prevalence rate of Rh-negative AB blood type is only 0.034%. And even more rare, the prevalence of p-type blood in the P blood group system (P1, P2, Pk1, Pk2, and p) is less than 0.001%, that is, one in 100,000.

If this is the case, Li Cha can only be considered unlucky for Ge Luo.

Fortunately, Gero has not been so unlucky, and there is still hope.

Then, the next step is to start preparing for blood transfusion.
