Chapter 1617
Melgen and the Elfins were all stunned when they heard Zhang Zian's words.
"Blood transfusion? You mean to transfuse blood to this cat?" Melgen subconsciously confirmed.
Zhang Zian nodded."That's right."
Fina's eyes lit up. It had never wanted to owe anyone a favor, but this time, it owed a huge favor because of its own carelessness. Although the blood transfusion could not fully repay it, it could at least make it feel better.
Therefore, it was the first to jump out and say,""Blood transfusion, is it? Use bengong's blood!"
"Scared? Blood ... Blood transfusion?" Snowy Lionet was so scared that it shrank its body, as if it was afraid of being caught and its blood drawn."Blood transfusion, does it hurt?"
Melgen continued to ask,"you mean ... We need to transfuse the blood of the other three cats to this injured blue cat?"
The other three cats were fina, snowy Lionet, and Galaxy.
However, Zhang Zian shook his head. He denied both Fina's request and melgen's inquiry."No, not their blood."
Snowy Lionet heaved a sigh of relief."You scared me to death ..."
Melgen and the other Elfins were stunned because there were only four cats here. If they did not use the blood of the other three cats, where would they find blood to transfuse to the blue cat?
Zhang Zian's gaze fell on famous, who was at the door. He walked over, squatted down, and patted its body."Famous, can I borrow some of your blood for Vladimir?"
"Ah?"
"Gah?"
"Squeak?"
"Meowmeowmeowmeowmeowmeowmeow?"
Melgen's eyes almost popped out of their sockets when she heard that. The Elfins 'jaws almost fell to the ground. They could not believe what they had just heard.
"Kaka! You idiot, I can understand your feelings, but are you so anxious that you've lost your mind?" Richard poked his head out of the hood and shouted.
Snowy Lionet: "it's over! It's over! This stinky man is out of his mind!"
Famous was also confused. It had always thought that it couldn't help."Uh ... I don't care, but can my blood lose to Vladimir?"
Melgen rushed over and grabbed Zhang Zian's arm,"Hey! Are you crazy? Although I don't know much about pets, I don't think a dog's blood should be given to a cat. It will definitely cause a serious rejection reaction. Not only will we not be able to save its life, but it will even ..."
This was a blood transfusion between different species. In her opinion, even if humans and monkeys could exchange blood with each other, it was impossible for cats and dogs to do so. After all, they were not even distant relatives.
"Yes, I can!"
Zhang Zian gave a serious and positive answer.
"Cats have blood types too. Most of them are type A, a few are Type B, and a few are type AB. Like humans, you can't mix different blood types." He looked at Vladimir and then glanced at the other cats."But I don't know what blood type it has, and I don't know what blood type they have. No matter which one of them I draw blood from and transfer it to Vladimir, it's a gamble."
In addition to this worry, he was also not sure if ancient cats like fina and snowy Lionet had different blood types from modern cats.
"But, even if it's a gamble, there's at least a 50% chance of winning. Didn't you say that most of them are type A?" Melgen still did not understand, and neither did the Elfins."But if we use dog's blood, won't we not even have a 1% chance of winning?"
Zhang Zian took out the syringe from the first aid kit, which he had found in the bathroom cabinet of the house.
"You don't understand. A dog's blood can be transfused to a cat, and you don't have to worry about the blood type." He explained as he prepared for the blood transfusion, or melgen might refuse to help.
"Since 1962, more than 60 cats have survived through the transfusion of dog blood, and four Related Papers have been published. The general principle is that the immune system of the serval cat will not immediately reject the first transfusion of dog blood cells. It will take about a week for the rejection to occur." He said.
"Ah?" Melgen was dumbfounded.
"The point is, the half-life of dog blood cells in a cat's body is only four days! Do you understand? Before the cat has a rejection reaction, the dog blood cells have all died naturally, and four days is enough to survive the critical period of urgent need for blood transfusion!"
As a good student with good character and academic performance, melgen finally understood that it was taking advantage of a time difference. The cat's immune system was relatively slow to react to dog's blood cells. By the time it reacted, the dog's blood cells that were transfused into the body would have died naturally. Therefore, there would not be a violent rejection reaction. It was much better than randomly transfusing cat blood and trying one's luck in the situation of unknown blood type.
"It's amazing ... Cats and dogs actually have such a relationship ..." She muttered,""There must be a reason why God arranged cats and dogs as human's closest animal friends ..."
"Then can we do the opposite? "Transfusing cat blood to a dog ..." She asked curiously.
"No," Zhang Zian said,"it's impossible to do it the other way around. After all, this is only an emergency plan, because a cat can only accept dog blood once in its life. If it's a second time, even if the blood comes from the same dog and is transfused to the same cat, the cat who is transfused will have serious rejection reactions."
The cat's immune system might have a slow reaction the first time, but it was not stupid. It would firmly remember the characteristics of dog blood cells and mark them as invading foreign objects. If dog blood entered the body the second time, it would immediately launch an immune attack and expel the dog blood as a foreign object. Not only would it not Save the cat's life, but it would also lead to the cat's death.
He was not very clear about the situation in North America and Europe, but basically all pet hospitals in China did not have a regular cat blood bank. Not to mention China, even the neighboring country, Japan, which was much richer and treated pets better than China, did not have a cat blood bank. When blood was needed, they could only temporarily draw blood from healthy cats in the hospital.
What if there were no healthy cats in the hospital at that time, or the cat was too old, too young, and too weak to draw blood? The only thing he could do was to tell the public and ask enthusiastic people to bring their cats here to donate blood.
What if it was in a remote place, no one nearby voluntarily brought cats to donate blood, or the situation was urgent and no cats were willing to donate blood?
If there was a dog nearby, as long as it was a healthy adult dog, it could be used as a blood donor in an emergency. Moreover, dogs were usually larger than cats, so the impact of blood donation was small.
However, there were very few people who knew about this. Occasionally, some people might have heard about it as strange news, but they did not understand the principle behind it. Even most veterinarians in China did not know about it. Fortunately, he knew a professional veterinarian who was a top student.
Zhang Zian handed melgen a syringe."If you understand, get ready to start. Listen to my command."
"Alright!"
Melgen took the syringe in excitement. Her heart was filled with a sacred sense of duty.
Famous squatted next to the coffee table and placed one of its front paws on the table."Come on!"
