It's not that hard to open a hospital in another world, right?

Chapter 1285 Research Reopened, Blood Replenishment Magic is Too Difficult!

No matter how much the elves screamed and wailed, they still could only hold the information that Gretel gave them, and gnawed to death with difficulty and pain.

Half of the time gnaws at the data, and the other half of the time, I have to endure the torture of the laboratory:

"Aseptic operation! Aseptic operation! Don't pick up things that fall on the ground!"

Snapped!The transparent hemostatic forceps flew over and accurately struck the errant's radial styloid process, making a whine.

"Who told you to put the lid down!"

Snapped!
The transparent hemostat was elusive, and the elf who made the mistake was at least at the level of a seven or eighth-level fighter, so he just didn't dodge it.

"With a gloved hand, don't touch the reverse side of another glove! Take off your glove, go out and wash your hands, and put your glove back on!"

Snapped!
The elves sighed, and so did Gretel.If it wasn't a last resort, he really didn't want to train these elves.God knows how difficult it is to engrave the aseptic operation standards into the bones, and make no mistakes at all——

It is common for medical students who have just entered the internship, even if they have been trained for several years, to be scolded and thrown out of the operating room;

It is also common for senior and mature doctors to make mistakes when putting on and taking off protective clothing, face shields and masks without special training, leading to self-infection;
As for ordinary people, the so-called wearing masks, disinfecting people, and leaking land can basically only reduce the probability of being recruited.If you want to say that you are 100% sure that you will not be recruited, basically, cough...

It can only be said that it is fate to be recruited, and it is also fate not to be recruited.

Of course, taking good protection in front of the epidemic can reduce the chance of getting sick. Even if you are accidentally caught, the least amount of virus inhaled will take longer to replicate and cause the disease, which can also give the body enough time to react and synthesize antibodies.

With more antibodies, the human body will suffer less damage, the symptoms will be lighter, and people will feel better...

It's like Gretel now.If one more assistant is trained, one more assistant will help him do these low-end tasks, such as collecting umbilical cord blood for rabbits.As for aseptic operation errors, the umbilical cord blood taken out cannot be used?
Anyway, dozens of rabbits are going to give birth in the first batch, and the female rabbits will give birth to 7 to 8 babies. Add up, there are hundreds of umbilical cord blood.

If you still can't practice, there will be a second batch, a third batch, and a fourth batch of rabbits...about every three days, a batch of rabbits will be produced, and the cycle will be once a month.

After so many rabbits have practiced, even the stupid and careless elves can reach the state of "no one else, but they are familiar with each other".

And with so many assistants, Gretel can focus on more valuable places.For example, directly inject the rabbit body with umbilical cord blood, and then try directed mutagenesis;
For example, throw a spell on the umbilical cord blood in an in vitro test tube to try targeted mutagenesis;

For example, try to extract stem cells from umbilical cord blood;
For example, try to use the magic configuration he designed to brush each of the unknown cells that have been separated by multiple centrifuges to see if they can be directional induced to differentiate into blood cells;

For example, for stem cells to differentiate into blood cells, they still need some environment, such as plasma.Gretel has to find ways to create a working environment for them, and use his imagination to match seven or eight dozens of versions...

buzz buzz buzz buzz buzz...

The centrifuge spins furiously.Gretel had a thick record book in his hand, with a pen curled up on the root of the oak stick, and he kept recording:
"In vitro experiment No. 2 plan, adding 72% of rabbit serum to the culture medium... Directed mutagenesis model No. [-]... [-] hours later, the suspension was drawn, and a smear was made for observation... A large number of bacteria appeared in the suspension, and the experiment failed..."

"Test tube No. [-]... smear microscope inspection, no living cells found... repeat three times, confirm that all cells are dead, the experiment failed..."

"Test tube number three..."

"Proposal No. 2, 0.5% of hare serum, 0.5% penicillin, [-]% streptomycin...directed mutagenesis spell model No. [-]..."

"Plan No. 2, 0.5% hare serum, 0.5% penicillin, [-]% streptomycin, release anticoagulant magic... Directed mutagenesis spell model No. [-]..."

"Ah ah ah ah..."

Gretel hugged his head and screamed.Can't make results, what is the problem?
Is there a problem with the spell model, or is there a problem with the extraction of hematopoietic stem cells, or the living environment of hematopoietic stem cells is not suitable?

Misfits are almost inevitable.Cells are very delicate things, and they are extraordinarily delicate when cultured in vitro.

Gretel didn't even need to do in-depth research. Using his shallow knowledge of physiology and biochemistry to think about it, he knew that there should be enough oxygen in the culture medium, and of course, the proportion of carbon dioxide should also be appropriate;

Suppressing bacteria is necessary, but if you add too much penicillin and streptomycin, problems will also occur;
In order to produce red blood cells, additional iron is necessary, which requires transferrin-then the question arises, how to extract, isolate, or make, human transferrin, or rabbit transferrin, add In the culture medium?

Ah, by the way, it seems that insulin needs to be added to supply enough sugar to the hematopoietic stem cells... So how should insulin be added?

In vitro experiments are not easy to do, and in vivo experiments are not easy to do either.Not only is it difficult to do, but you also have to slap the table with the elves under their eyes of surprise, fear, and contempt:
"Learn to draw blood!—I'll give you one day, everyone, to learn to draw blood from rabbits!"

"Learn how to use a syringe correctly! Learn to identify blood vessels! Learn to draw blood from a rabbit's veins correctly and safely! Each rabbit should draw blood no less than 15ml and no more than 20ml!"

"Learning smears, microscopy, and counting blood cells!"

"Learn blood cell counting magic!"

The elves wailed.For the servants of nature, it is still acceptable to take cord blood from rabbits. After all, the umbilical cord is useless anyway after the birth of a baby rabbit, and wasting cord blood is also a waste;

However, grabbing rabbits one by one, immobilizing them, controlling them with spells, and drawing blood from them...

Every whine, every struggle of the body in the hands, the warm breath blowing on the arms, the wet eyes looked at him pleadingly...

The stronger the elf's healing skills, the deeper the connection with nature, and the more sensitive the animal's emotions are; every bit of fear and pain of the experimental animals seems to be directly cut into their hearts.

"No...can you stop torturing them..."

"The experiment on the rabbit is to find a way to replenish the blood of the soldiers who have lost too much blood! The faster you do it, the more accurate, the faster the research progress, the less the rabbit will suffer!"

Gretel suppressed their resistance without hesitation:

"Enhancing the recovery ability of soldiers is to enhance the combat effectiveness of soldiers! If the soldiers can't stand it, the plants and animals that suffer, and the nature that suffers, will be hundreds of times and thousands of times more than the dozens in the laboratory!"
