In the laboratory, an indescribable smell permeated the air. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

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

It is said that the girls are a very magical species, and Yang Tian once again confirmed this today.

While covering his nose and frowning and saying that it stinks, he also leaned in to watch and shout that it was so cute.

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

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

They were originally sitting in the front row, but Xie Xin, the girl, actually came directly to the front row!

Yang Tian wanted to ignore her, but even if he turned his back to Xie Xin, his body would naturally react, his hair stood up, and he simply left two positions in the back row, and decisively pulled the little fat man backwards.

The boys and girls in their laboratory are also singular, and the one who came out of the single happened to be Xie Xin, and the one who partnered with her was a thin little boy, Yang Tian felt that they looked very compatible......

"It's time for class, students are back in their seats."

At the beginning of class, the teacher picked up the mice to teach, and Yang Tiancai found that the mice provided by the school were different from those in the system!

The mouse in the teacher's hand is still white, but the bare skin of the limbs, including the long tail, is blue!

The normal skin of mice is flesh-colored, which is the common pink and pink 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 by which macrophages in mice engulf foreign chicken red blood cells.

Phagocytes are a type of white blood cell derived from blood mononuclear cells, histiocytes, and Kupff cells.

Its main function is immunity, containing a variety of lysosomes and swallowing vesicles and a large number of mitochondria, which can engulf large pathogens, foreign bodies, and fragments of necrotic tissue.

Under normal circumstances, the content of phagocytes is extremely scarce, and only occurs in large quantities when there is invasion of foreign enemies, chronic inflammation in the body, or later stage of acute inflammation.

In order for the students to smoothly observe the process of phagocytic cells engulfing foreign bodies, the laboratory teacher needed to inject sterile thioglycolic acid broth into the abdominal cavity of each mouse three days in advance to promote the proliferation of phagocytic cells.

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

Brilliant Blue G can temporarily turn the skin of the mouse bright blue, and since the broth is injected at the same time, the mouse turns blue, which means that it can be used for experiments.

The teacher in charge of Yang Tian's laboratory was obviously a little absent-minded, hurriedly explained the experimental steps, waved his hand and let the students start by themselves, and sat on the podium and began to be 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, and they didn't know where to start in front of the cage.

Say that they are afraid of mice, girls may be afraid, what are men afraid of?

But the teacher just said that this rat can bite!

In the past, when doing experiments, the school would also be equipped with gloves, not the thin plastic gloves, but the super thickened version, and the mice could not bite through it.

However, due to the inconvenience of wearing such gloves and the financial problems, gloves are not provided as they are now.

If you catch this with your bare hands, if you are accidentally bitten, not to mention the pain, you have to go to the rabies vaccine, and you have to toss for a month, who will do it!

Everyone cowered and didn't dare to stretch out their hands, and Yang Tian pulled the little fat man to squeeze in front of the cage.

"Yang Tian, will you arrest it? I, I ......"

"Okay, what are you afraid of a big man, I'll catch it, and you can watch from the side."

Yang Tian was speechless for a while, it was still easy to partner with Han Bing, at this time, even if Han Bing didn't catch mice, he should have already brought over the slides, coverslips, pliers, scissors, syringes, etc.

Really, why regroup......

Pushing aside the crowd, Yang Tian squeezed to the front, scooped up the little fat man with one hand, opened the cage with one hand, probed inside, easily grabbed the tail of a mouse and lifted it up, and closed the cage again.

"Wow!"

"That's amazing!"

"This is easy to catch, the eyes are fast!"

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 while the mouse scratched in the air.

"The mouse can be caught with both hands and one hand, with both hands, lifting the tail like I did, putting the mouse on the cage or other rough surface, and gently pulling it back."

Yang Tian explained and demonstrated, and everyone exclaimed again.

"Mice are crawling forward!"

"Look at his paws!"

"That's straight! The teacher didn't say anything like this! ”

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 forefinger, you see." ”

In order to prevent the mouse from turning his head and biting, Yang Tian grabbed more skin, and the fur on the mouse's neck arched an arc, which looked like a scarf from the front.

"It's amazing!"

"That's not it!"

"Your movements are so skillful, how can I look better than the teacher?"

Yang Tian put the mouse down again, picked up his tail, and pulled the little fat man, "You want to try?" ”

"I'm coming!"

A hearty female voice sounded, Yang Tian instantly exploded, and as soon as his hand was released, the tail of the mouse was taken over by a slender hand.

Put it on the cage, pinch it with his left hand, and then wrap the tail around the little finger of his left hand and clamp it on the inside of his palm, Xie Xin's movements are even more skilled than Yang Tian!

The sense of resistance from the bottom of his heart prompted Yang Tian to quickly grab a mouse from the cage with his tail, and just like that, he grabbed the little fat man and squeezed it out, and the classmates exclaimed while quickly avoiding the side, no one wanted to be bitten by the mouse.

He just wanted to stay away from Xie Xin, this goosebump was about to fall to the ground......

"What!"

Xie Xin in the crowd pouted, and just wanted to chase out, but was stopped by overlapping classmates.

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

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

Open the needle, suck up 2ml of the chicken's red blood cell solution, grab the mouse, inject it intraperitoneally, rub the belly, and throw it into the inverted beaker.

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

After fifteen minutes of waiting, Yang Tian quickly extracted normal saline, injected it, rubbed his stomach, and then neatly implemented the "cervical dislocation method".

"Click!"

With a soft sound, the mouse was declared dead.

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

Yang Tian's manual was fast, the little fat man was dizzying and dumbfounded, and when he reacted, Yang Tian had even adjusted the microscope, and found the best field of view in three clicks and observed the target cells.

"That's it?" The little fat man has his mouth half open, and the other students are still arguing about how to inject the needle and how not to puncture the internal organs! The fastest Xie Xin has just killed the mouse!

"Okay, the experiment is done, you just draw according to this cell, I'll go out and catch my breath......"

Yang Tian turned his head and left, although now he and Xie Xin were far away from each other in the front row and the other in the back row, but why did he always feel like he couldn't breathe?

Slipping out of the back door with his chest covered, Yang Tian walked in the direction of the toilet, and there was a scream from the first laboratory on the left hand side of the cold left-

"Ahhh

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