Chapter 524: We Are Not the Race that Understands Blood Best. Wuwu

Does oxygenated arterial blood taste good?

That's good.

Amid Viscount Sebesh's gushing surprise, Grete packed up the test tubes and smiled slightly:

"So, is this little trick enough to convince your Lord Marquis to participate in research and development?"

"It's definitely not enough!" Viscount Sebesh raised half a beaker of blood to the tip of his nose, sniffed it carefully, and then rubbed it carefully with the tip of his tongue:

"The processed blood does taste better, but it still can't be compared with fresh arterial blood! It's sour and has a bad smell~~~"

Oh, that's definitely different. What the venous blood carries are waste products from human body metabolism, carbon dioxide, excess electrolytes, and various other things. Arterial blood carries oxygen and nutrients.

Therefore, the extracorporeal circulation device needs to use a semipermeable membrane or something to allow oxygen to enter, carbon dioxide to come out, and to filter out uric acid and other things. If you ask me to do it now, I can’t do it~~~

Gretel was calm and collected. Uric acid, carbon dioxide, electrolytes, and various ions are all dissolved in the plasma. If we can’t make a semipermeable membrane, we can just separate it and that’s it!

"If you think it tastes bad, I have another way. Do you want to try it?"

"want!"

"Okay, go to the hospital!"

There are centrifuges in the hospital. The blood with added anticoagulant magic was put on the centrifuge and it buzzed. One end of the blood cells and the other plasma were perfectly separated.

Grete did not distinguish between stem cells, lymphocytes, white blood cells, platelets, etc. He released all the blood cells and added potassium chloride and calcium chloride in proportion to Ringer's solution, which is physiological saline, according to the specific volume. ——It fell in with a crash.

Stir evenly and centrifuge once to wash away the remaining plasma. Then, add Ringer's solution according to the standard hematocrit.

Anyway, during clinical blood transfusion, Ringer's solution is used to mix blood cells, huh. Then, oxygen was pumped inside to turn the color into bright red.

"Come on, have a taste -"

Viscount Sebesh took it dubiously. Hold it in your hand, shake it gently, and observe the color depth and clarity of the cup of blood, whether there is any hanging cup, whether there are bubbles...

"It always feels weird to drink blood from a beaker. Could you give me a goblet next time?"

no. Grete rolled his eyes at him. I see you appreciating wine with wine, and I think it’s weird too!

Viscount Sebesh shook enough blood, held it in front of him, and took a deep sniff. Open your nose and try your best to introduce the gas molecules above the beaker:

"Tasteless?"

He frowned, sniffed it again in disbelief, sniffed it again, felt heartbroken, and simply took a big sip. Then, turning to Grete, he expressed his sorrow:

"Mage Nordmark, you are so wasteful! Why is there no flavor at all? It's bland - just like, just like -"

"Alcohol?"

Grete helped him make up a word. Viscount Sebesh looked at him blankly, and Gretel turned around and poured a few milliliters of alcohol and handed it to him for a taste. Mr. Viscount drank it all in one gulp and nodded vigorously:

"That's right! That's it! It's still the same thing, but it has no taste! How did you do it! You ruined all the good taste!"

That's for sure. Grete spread his hands.

It's like distilling alcohol from wine. Those complex aromatic substances-components that make up the flavor, such as esters and fusel oils, are all left in place. Take a sip, it's like drinking a sip of burning water, taste? what is that?

As for the ingredients that vampires think are flavor, Grete estimates that most of them are thyroxine, adrenaline, androgens, estrogen, etc., which are also dissolved in the plasma.

The blood cells are separated, washed, and all plasma is removed. Then, mix it with Ringer's solution in proportion...

Sorry, it must be bland, it has no flavor at all. This is not as good as high-purity vodka, at least it's still strong.

But you can still drink it. Viscount Sebesh took a small sip and finished the glass of blood with great care, frowning:

"It's still drinkable. Well, it can't be compared to fresh human blood, but it's still pretty good. You don't know, sometimes when you go out without a blood slave, and you can't find a good hunting target, the blood you suck will That stinks..."

Grete: ...Thank you, I don’t want to hear it, I don’t want to know at all. Can you please not tell me your one hundred and eighty thoughts about hunting and sucking blood?

Obviously not. Viscount Sebesh muttered and babbled, took a sip of blood and said a few words. After finally finishing drinking, he suddenly let out a long sigh and squatted on the ground like a potato.

Gretel: "...What's going on?"

"I have never thought about these practices... Why they are done like this, I don't understand..." Viscount Sebesh held his head and whined:

"We are not the race that understands blood best..."

...What is there to be proud of in this false name?

Gretel didn't understand at all. However, this does not prevent him from taking advantage of the situation:

"So do you want to participate in my research? - If you do, the research is done, and you are still the race that understands blood best! I will add you as the first author!"

"good!"

Potatoes sprout, shoot, and grow taller. Viscount Sebesh jumped up again and geared up:

"Where do we start?"

Start by verifying your blood type. In other words, start by verifying that vampires also have blood types. Gretel is still somewhat confident about this: the vampires, although they are undead creatures, were once humans. Since we are human beings, then maybe, maybe, maybe, we also have blood types?

What's more, they still have rejection reactions. This is also a kind of validation, isn't it?

Viscount Sebesh frowned and stretched out his right hand. He muttered and kept saying:

"It's a shame, it's a shame, why do I have to let you draw my blood... If I had known I was going to do this today, I would have brought a descendant over and let you draw his blood... Hiss! Be gentle!"

"I'm already light enough..." Gretel had no expression on his face, pressing left and right, right and left on the inside of his right elbow. It’s not like I want to use force. Why is your brachial vein so deflated? It’s hard to press it!

Fortunately, he never lost his skills. Emergency first aid, opening intravenous access, etc., you have to do it when you are in a hurry, you can't always wait for the nurses to do it. After pressing for a while, I finally found the right spot and inserted a needle into the vein.

Then.

Then.

Grete looked at the syringe, at the liquid gurgling out of the syringe, and then at Viscount Sebesh. Your blood is wrong!

Why is the color of the liquid extracted from the blood vessels so pale!

I have treated patients whose hemoglobin dropped to 30g/l, but they were not that low! Are you sending me a drop of blood mixed with 5 ml of normal saline?

Under his doubtful and accusatory gaze, Viscount Sebesh turned his head with a pale face:

"What are you looking at me doing? - The true blood of the Vampire Clan is not so easy to obtain! Give me some time!"
