Taking dozens of blood from Gro’s wound and dropping them in clean silver plates, Richard looked up and said to the nobles: “Next, I’m going to take a drop of blood from each of you to come to Hege Luo’s blood is mixed. This is because there is very little blood in Gro’s body, so you must find someone who can give him blood and inject some blood into his body to restore him to health and save him. So each of you This test is required."

　　 Blood transfusion?

　　Not only not bleeding? Transfusion?

　　 is indeed a heresy, really a wizard's spell!

　　 But this time it is time to show loyalty.

"Every one of us can give blood to the prince!" In the crowd, I don't know who said such a sentence, and then caused the agreement of many people, "Wizard, if you can save Prince Gro, you can use our blood. "

　　 Richard shook his head and said: "Not everyone can do it, only qualified personnel."

　　 "Why?" Someone in the crowd asked.

"The reason is simple." Richard pours out a breath. "Blood and blood are not exactly the same. Generally speaking, blood is not a pure red liquid, it contains many other substances. If some substances are different, blood will produce ...Well, it’s toxic, so blood can’t be lost casually."

　　 This is explained by Richard as much as possible with a group of people who can understand it. After all, the other group of people is not the maid, craftsman or soldier in the former palace.

　　In the royal palace, Li Cha said that no matter how complicated, maids, craftsmen, and soldiers will also try hard to understand, and they can cultivate some vague scientific thinking, and then select some excellent people from them to cultivate and use.

　　 So if you are in the palace, facing some ordinary soldiers and craftsmen, Richard will say more details, some blood components, explain plasma, blood cells and the like, and see the reaction of the other party.

　　When faced with the maid, it will explain more, and will say some reactions of specific antigens (agglutins) on the surface of red blood cells. For example, the classification of ABO blood type, such as what kind of agglutination type A blood, what kind of lectin is in the serum, the input of the blood type will not cause agglutination, will not cause blood vessel blockage and hemolysis and so on. Even if the maid doesn't understand, it doesn't matter, remember that there is always nothing wrong.

　　 But now, in the face of a group of strange nobles, obviously there is no value to cultivate and use, so Richard is too lazy to explain the scientific knowledge in it, and just use some of the most plain words to explain.

　　 But even so, everyone was stunned, surprised by what Richard said, and then gave birth to a lot of doubts.

　　 "Is the blood poisonous?"

　　 "How can blood be poisonous?"

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

　　 "Blood..."

　　 This is a disadvantage that has not been explained in detail, because without the support of a complete system, even if there is a place beyond the ordinary people's cognition, it will immediately cause more doubt and curiosity. In this case, if you directly narrate a complete set of theory, no matter whether the other party understands, but it can definitely let the other party shut up.

But until now, Richard doesn’t want to waste much time to remedy anything. He directly said: "You don’t need to understand why the blood is poisonous, you just need to know that I did it for a reason. If you don’t want Gro to die, just Follow my words, of course, if you want him to die, just say nothing."

　　 "Amount......"

　　Everyone looked at each other, not calm, and finally stepped forward to start the blood test.

　　 Suddenly Richard thought of something and asked, "Oh, by the way, who is Gro's close relative in your crowd? All immediate relatives within three generations count, such as siblings, cousins, etc."

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

　　 was watched by a short aristocrat who tried to maintain his apparent calmness and looked at Richard: "I am, what's wrong?"

　　 "Then you don't need to test blood anymore." Richard said, and he was very sure, "You are ruled out."

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

　　 "Are you sure I want to explain?"

　　 "Well, this..." The other party thought for a while and thought that Richard had really explained it, and couldn't understand it. Finally, he shook his head and said, "Forget it."

　　 Richard said, "You are very smart."

　　 "Amount."

　　 In fact, Richard really explained, and the other party did not understand. Because it involves biological knowledge, it is more complicated than blood type.

　　Because of the misleading of many film and television works on modern earth, many people think that when someone needs a blood transfusion, they can use the blood of the same type of their close relatives, preferably their immediate family members.

　　 Only in this way can we show the love of father and mother and the filial piety of son and son. More importantly, in this way, the old news of love may have been discovered many years ago, and then the dog blood bridge section where his son is not a pro son and the nurse is a pro daughter.

　　 But in reality, people who dare to blood transfusion in close relatives 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 if transfusion of untreated fresh blood between immediate relatives may cause graft-versus-host disease (GVHD). Once it occurs, the mortality rate is as high as 99.9%, and basically no rescue is needed.

　　 This is because the blood is usually mixed with donor lymphocytes. Under normal circumstances, when the patient is transfused, the immune organ will recognize and eliminate lymphocytes in the foreign blood that are different from themselves~www.readwn.com~ But if it is blood of a close relative, it cannot be recognized because of the similarity of genes, and the default is harmless , A pseudo-acquired acquired immunodeficiency syndrome (AIDS, or AIDS).

　　This leads to the fact that foreign lymphocytes can survive and proliferate in the patient's body, and then attack various tissues and organs of the patient, causing the patient to have fever, rash, diarrhea, lymphadenopathy, hemolytic anemia, etc., and eventually die.

　　 For this, Richard did not want to bet on luck, test how lucky Gro is. I don't want to get everything done, but in the end it was messed up by a graft-versus-host disease caused by a blood transfusion by a close relative. It might as well not be done from the beginning.

　　 Breathed lightly, Richard looked at the silver plate.

At this time, the nobles had finished the blood test separately, and the results were not very good. Gro’s blood should be a relatively rare AB blood type. According to the statistics of modern earth, the ratio of this blood type only occupies 7%, so the people present There is only one match.

　　 But it is not the worst. After all, in addition to the ABO blood group, there are more complicated blood group systems, such as the Rh blood group system, Hh/Mumbai blood group system, sub-Mumbai blood group system, P blood group system, Yidabao blood group system, etc.

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

　　If this is really the case, Richard can only be considered bad luck.

　　 Fortunately, Gro hasn't been unlucky to such an extent, there is still a rescue.

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