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

Chapter 156 Gretel's Animal Experiments (Second Change)

In the next half month, Gretel plunged into animal experiments in addition to routine lectures.He, Matthew, has a beak protective suit for each person.As for Bernard, he had no choice but to use bubble technique + gauze mask to help with some heavy lifting——

It is said that the barbarian's physique comes from +2?Or toughness +2?In short, Grete felt that Bernard could at most make Bernard sneeze if he could get rid of his illness...

All in all, the safety of the experimenters is reassuring for the time being.Gretel designed the process as carefully as possible, and with the help of Pastor Matthew, began to conduct animal experiments:
All healthy animals have one cage for each, pay attention to the orientation and air flow direction, and try to prevent the air between the cages from communicating with each other, so as to avoid cross-infection of experimental animals (Pastor Matthew kindly gave birth to vines and grass blades to weave cages, calling on the ground the earth rises to form the walls and divide the cage);

One-third of the experimental animals, put one bat in each cage, and observe whether the experimental animals live with the bats and whether they will be infected;
One-third of the experimental animals were treated in different ways: adding bat urine, bat feces, bat saliva, and dust from bats to the feed and drinking water, or using cotton swabs to pick up bat oral secretions, Rubbing the nasal cavity of experimental animals;
The remaining one-third, kept in normal cages, served as the control group.

Feed every day, observe animals every day, write records every day...

Gretel was really grateful to this Pastor Matthew.We can weave cages, build earthen walls, catch sheep, pigs, rabbits, and bats, and you can never make mistakes when adding food and water. Cleaning animal cages is not too dirty, and moving feed is not too hard.Without his help, I really couldn't do this animal experiment for a day:

Gretel tried to catch a rabbit once. He reached into the cage and touched it for 1 minute, but he couldn't catch it.In the end, the rabbit kicked on the back of the hand. If it wasn't for the quick withdrawal of the hand, I doubt that the fingers could break it.

Not to mention ferrets that are as fast as lightning, goats that can stand up to people, and black pigs that can weigh at least a hundred catties...

Gretel only glanced at it, and gave up the idea of ​​doing it himself.

Standing beside him, he instructed Pastor Matthew: "Grab this rabbit! Turn it upside down! Take the temperature! Insert the thermometer in! - Oh, don't interrupt, I only have one thermometer, don't let it chew it up! Mercury poisonous!"

"...Then where should it be inserted?"

Gretel stared into Pastor Matthew's eyes under the bird's beak mask, closed his lips tightly, and resolutely refused to speak.

And Pastor Matthew did not blindly work hard because of the teacher's entrustment.In fact, every time he does something, there are countless questions to ask:
"Why do you have to prepare so many kinds of animals?"

"Because I don't know which species bats can infect." Gretel looked at the cage with regret.So many kinds?I still think I am less prepared!

In theory, mice, rabbits, dogs, pigeons, and pigs, horses, and sheep known to be intermediate hosts must be prepared.If possible, there are also civet cats and pangolins—well, forget about the latter, to protect animals...

"Why feed them bats with... er, something different?"

"Because it is necessary to determine the route of transmission..." Fecal-oral transmission, droplet transmission, body fluid transmission, different routes require different defense methods.When it comes to disease defense, Gretel has a long history of sharing knowledge:
"For example, if you sneeze and get sick from inhaling it, you have to cover your mouth and nose like we do... If you eat dirty things in your mouth, you must wash your hands before meals..."

"Then why do we have to prepare more than twenty of each kind?"

"Because animal experimentation is a gamble on probability... oh, it's a gamble on possibility. Seeing that there are so many animals, if you get one point for each type of bat, there won't be many left."

What is twenty?

The little buddy next door in the field of pharmacy talked about the gossip. Whenever a new drug is tested, and the half-lethal dose is tested in the first phase of clinical trials, it will take dozens or hundreds of animals to start.Note that there are dozens or hundreds of mice, dozens or hundreds of pigeons, rhesus monkeys...

Oh, rhesus monkey Jingui, all other experimental animals are dead, and relatively harmless drugs are screened out, and then tested with rhesus monkeys.

Even when he was studying in his previous life, in order to let the students of clinical medicine experience and conduct a half-lethal dose experiment, he had to divide a class into 8 groups, with 6 to 8 mice in each group.After doing the math, it takes 48 of them to see whether it is good or bad.

Unlike him here, there are only two or three of each transmission route, each type of bat, and the same animal.This broken probability made him terrified.Whether it can make a result, it feels like a matter of pure character.

In other words, whether the early warning can be successfully issued, probably the luck of the Magic Parliament is at work?
Gretel answered without hesitation, and Pastor Matthew kept these unclear knowledge in mind one by one.Even if God knows what it can be used for, but if others are willing to share generously, it is worth his hard work to help.

"Why do you have to be half male and half male again? We have been looking for male pigs and rams for a long time..." Especially male pigs.Many young boars were killed and eaten, and the breeding pigs were not so easy to borrow, they were just a bag of tears.As a last resort, I went to the woods to catch a group of wild boars...

"Because of different diseases, the probability of getting sick may not be the same for male and female individuals...

Alas, poor... Gretel looked around the corral, and shed tears of sympathy for herself.According to the orthodox experimental design method, doubling the number of experimental animals may not be enough, but...

At this point, he could hardly support him anymore.

If you can afford it, there is no one to take care of it. There are people to take care of it, but there are not so many people. They grab the animals one by one to measure their body temperature...

Alas, it's no wonder that big companies make new drugs.When his status rises in the future, he must ask the Magic Council for a research group to help him raise experimental animals...

Gretel added another reason for himself to work hard to upgrade.Holding a notebook, Pastor Matthew measured the temperature of the animal, and he wrote down next to it:
"Hare No. 12, body temperature 39 o'clock...well, it's 39.2 o'clock, [-] degrees, normal food intake, normal spirit, normal bowel movements, no abnormal secretions from the eyes, nasal cavity, and oral cavity, good health...I tell you this Why do you need to measure the rabbit when it is normal?"

"Then it needs to be measured! — Besides, how can you guarantee that it is definitely normal?!"

"I can communicate with it! Any servant of the God of Nature can do it - no, you won't?!"

"Uh……"

Gretel, serious partiality, mixed in, Nordmark, except for healing, the other skills of the priest of the God of Nature, don't know anything...
