super medical system

Chapter 74 The Blue Mouse (Part [-])
In the laboratory, an unspeakable smell spread in the air.

This is the unique smell of rodents such as mice. The system has mentioned it, but it has not simulated it. I don't know if it is because there is no such function, or because the mice provided by the system always appear alone.

It is said that girls are a very magical species, Yang Tian confirmed this again today——

While covering his nose and frowning, he said it stinks, and at the same time he leaned over to watch and shouted how cute it was.

I really don't understand their brain circuit...

Yang Tian didn't go up to watch, but dragged the little fat man to the back of the classroom.

They were originally sitting in the front row, but the girl Xie Xin also rushed to the front row!

Yang Tian deliberately wanted to ignore her, but even with his back to Xie Xin, his body would react naturally, his hairs stood on end, and there were just two seats left in the back row, and he decisively pulled the little fat man back.

The boys and girls in their lab are also in odd numbers, and the single one happens to be Xie Xin, and her partner is a thin and thin boy, Yang Tian feels that they look pretty good together...

"Class has started, students return to their seats."

At the beginning of the class, the teacher picked up the white mouse to teach, and Yang Tiancai discovered that the school provided a different mouse than the one in the system!
The white mouse in the teacher's hand still has white fur, but the exposed skin of the limbs, including the long tail, is blue!

The skin of normal mice is flesh-colored, which is the usual pink and tender color, but the mice prepared by the school today have been specially treated.

Today's experiment is a companion experiment in cell biology to observe the process of macrophages in mice phagocytizing foreign chicken red blood cells.

Phagocytes are a type of white blood cells derived from blood monocytes, histiocytes, and Kupffer cells.

Its main function is immunity. It contains a variety of lysosomes, phagocytic vesicles and a large number of mitochondria, which can phagocytose larger pathogens, foreign bodies, and fragments of necrotic tissue.

Under normal circumstances, the content of phagocytic cells is extremely rare, and only when there is invasion of foreign enemies, chronic inflammation in the body, or the late stage of acute inflammation will they appear in large numbers.

In order for the students to observe the process of phagocytes engulfing foreign bodies smoothly, the experiment teacher needs to inject sterile thiolacetic acid broth into the peritoneal cavity of each mouse three days in advance to promote the massive proliferation of phagocytes.

In order to ensure the effect of the broth, a special substance - "Brilliant Blue G" is injected at the same time.

Brilliant Blue G can temporarily turn the skin of mice into bright blue, and because the broth was injected at the same time, the mice turned blue, which means they can be used for experiments.

The teacher in charge of Yang Tian's laboratory was obviously absent-minded, explained the experimental steps in a hurry, waved his hand to let the students start by themselves, and sat on the podium in a daze.

This time it was to catch mice, which was even more exciting than last time, and the students were even more chaotic, surrounded in front of the cage, not knowing where to start.

Let’s say they are afraid of mice. Girls may be afraid, but what are men afraid of?

But Teacher Ren just said that this mouse can bite people!

In the past, when doing experiments, the school would also be equipped with gloves, not the kind of thin plastic gloves, but the super thick version, which the mice could not bite through.

However, due to the inconvenient operation with that kind of gloves, coupled with financial problems, it has become the case that gloves are not provided now.

If you grab it with bare hands, if you accidentally get bitten, not to mention the pain, you have to get a rabies vaccine, and you have to toss for a month, who will do it!

Everyone was timid and afraid to stretch out their hands, Yang Tian dragged the little fat man to squeeze in front of the cage.

"Yang Tian, ​​will you catch it? I, I..."

"Okay, what are big men afraid of? I'll catch it, and you can just watch it."

Yang Tian was speechless for a while, and it was still easy to partner with Han Bing. At this time, even if Han Bing couldn't catch mice, he should have brought the slides, coverslips, forceps, scissors, syringes and so on. up.

Really, why don't you regroup if you have nothing to do...

Pushing aside the crowd, Yang Tian squeezed to the front, grabbed the little fat man with one hand, opened the cage with the other hand, poked inside, easily grabbed a mouse by its tail and lifted it up, and then Close the cage.

"Wow!"

"Amazing!"

"It's easy to catch, quick eyes and quick hands!"

All the girls let out a burst of exclamation, and many men's eyes widened, eager to try, but they were afraid of being bitten.

"Fatty, look."

Yang Tian raised his tail, and the mouse scratched in the air.

"Mice can be captured using two-handed and one-handed methods. Two-handed methods, like me, lift the tail, put the mouse on a cage or other rough surface, and gently pull it back."

Yang Tian demonstrated while explaining, and everyone exclaimed again.

"The mouse is crawling forward!"

"Look at his claws!"

"It will be straightened like this! The teacher didn't mention it will be like this just now!"

Yang Tian stretched out his left hand, "At this time, you should quickly pinch the skin on the back of the mouse's neck with your left thumb and index finger, look."

After practicing thousands of times in the system, Yang Tian pinched the mouse with ease. In order to prevent the mouse from turning its head and biting, Yang Tian scratched a lot of skin, and the fur on the mouse's neck arched an arc. From the front, it looks like wearing a scarf.

"so amazing!"

"It's almost over!"

"Your movements are so skillful, why do I look better than the teacher?"

Yang Tian put the mouse down again, picked up the tail, and tugged at the little fat man, "Come and try?"

"I come!"

A hearty female voice sounded, and Yang Tian frowned instantly. As soon as he let go, the mouse's tail was picked up by a slender hand.

Put it on the cage, pinch it with your left hand, and wrap the tail around the little finger of your left hand and the inner side of your palm. Xie Xin's movements are even more skillful than Yang Tian's!
The sense of resistance from the bottom of his heart prompted Yang Tian to quickly grab a mouse out of the cage by its tail, and just like that, he grabbed the little fat man and squeezed out. Avoid by the side, no one wants to be bitten by a mouse.

He just wanted to stay away from Xie Xin, the goosebumps were about to fall all over the ground...

"what the hell!"

Xie Xin in the crowd pouted, and was about to chase after him, but was stopped by piles of classmates.

"Well, can you catch one for us...just grab it out of the cage."

Xie Xin was stopped in the crowd to catch the mice out of the cage, while Yang Tian led the little fat man to quickly collect all the experimental equipment.

Open the needle, absorb 2ml of chicken red blood cell solution, catch the mouse, inject it intraperitoneally, rub the belly, and throw it into the large upside-down beaker. Yang Tian didn't bother to explain to the little fat man, and the action was done in one go.

His only thought now is to finish the experiment as soon as possible, leave the laboratory as soon as possible, and stay away from the "allergen" Xie Xin...

After waiting for 15 minutes, Yang Tian quickly drew out normal saline, injected it, rubbed his stomach, and then performed the "cervical dislocation method" neatly.

"Crack!"

With a bang, the mouse was declared dead.

The next step is to take fluid from the peritoneal cavity, make a smear, and observe it under a microscope.

Yang Tian's hand movements were fast, and the little fat man was dazzled and stunned. When he reacted, Yang Tian even adjusted the microscope, and found the best field of view to observe the target cells in two or three clicks.

"That's it?" The little fat man half opened his mouth, and the other students are still arguing about how to give the needle and how to inject without puncturing the internal organs!The fastest one, Xie Xin, just killed the mouse!
"Okay, the experiment is finished, you can just draw it according to this cell, I'll go out to catch my breath..."

Yang Tian turned his head and left, although now he and Xie Xin were far apart in the front row and the other in the back row, why did he always feel flustered like he couldn't breathe?
Clutching his chest and slipping out of the back door, Yang Tian walked towards the toilet, and suddenly there was a scream from the first laboratory on the left——

"Ahhh!"

Yang Tian turned his head, two balls of white and blue things were running happily on the ground, the target was in his own direction.

　New year, new weather, happy new year!The first release of three consecutive updates, and there are still manuscripts left, it depends on everyone's hard work!
