Lab mice, speaking nicely, are generally mild in temperament, and unpleasantly speaking, they are dumb in the group. I do n’t know if it ’s because of inbreeding.

Recently, Zheng Tan often hears about this from papa's genetics course ppt, so when he saw that caged mouse, Zheng sighed that this was really the same as what papa Jiao said. Fear was seen in the eyes of several mice, and they might even think that the breeder had arrived and were busy begging for food.

Dao Jiao grabbed a little mouse from the cage and placed it on the table, sighing to Zheng: "Look at it, don't let it run around."

叹 Zheng sighed and looked at the little mouse who didn't know he was about to face doom, and raised a paw to hold down the little mouse's tail. The mouse that was held down by the tail didn't struggle too much, but showed a posture to crawl forward.

Look, this is the difference between wild and domestic, if the mice outside are held down by their tails, they will either desperately break free or take a bite in turn.

Dao Jiao put the cage with the remaining four mice in an empty cardboard box so that they could not see what was happening outside.

"I don't know how your cats catch mice, or **** them. I'm just telling you about the methods we usually use."

He said that Dao Jiao took the little mouse from Zheng Tan's claw.

"Let me tell you, in domestic laboratories, the basic method is to kill the neck. This is also the least painful method of killing mice. If the method is sharp, it will not feel pain at all, and it is also in line with foreigners. Speaking of animal welfare ... "

叹 Zheng Tan squatted and watched quietly. He knew that Dao Jiao had entered the teaching state again. Sometimes, at home, after Dao Jiao was preparing to teach PPT, he would try to talk first, and the listener was Zheng Tan. Therefore, Zheng Tan knew that Dao Jiao had spoken the words "I'll tell you" and he knew that he was back in teaching.

"Killing the neck by severing it means that the cervical spine is dislocated and the spinal cord is disconnected from the brain stem. One hand holds the mouse's neck with a tool or directly, grasps its tail with the other hand, and pulls hard with both hands , That's fine. This is one of the methods, and the other method is also often used by you. You can also try it and watch ... "

As Dao Jiao spoke, he grasped the mouse's tail with his left hand, and moved the thumb and index finger of his right hand to the mouse's neck down.

Then there is no more.

叹 Zheng Tan looked at the motionless mouse on the desktop, then looked at Dao Jiao with the expression "I am optimistic about you", and twitched his ears.

看 "Look, the operation is actually very simple, even if you haven't caught a mouse before, it doesn't matter, it's just a matter of practice. I have seen your speed when you hit A Huang, and there must be no problem in catching up with the mouse."

A Huang in Dao Jiao ’s mouth is a yellow tiger cat, and one of the **** friends that Zheng Tan knew after becoming a cat. Unlike the "Sheriff", A Huang always does something weird, many When Zheng Tan looked at it, he wanted to go and smoke it, but Ahuang didn't show up recently. I don't know why.

Dao Jiao caught another little mouse and asked Zheng Tan to try it himself.

Zheng Zheng slayed the first one three times before letting the poor mouse completely die.

When slaying the second mouse, Zheng Tan exerted too much force, but at least the mouse died before he felt the pain. Zheng Tan was also more fortunate that she had become a cat instead of a mouse. The next step in the food chain pyramid was to face a **** of a hell.

"Dislocation of the cervical spine is easy. The mouse's cervical spine is very fragile. You are mainly unskilled," Dad Jiao said with a voice beside him. "Do not hesitate to take a shot. It is best to succeed once, otherwise the mouse will be very painful However, note that the spinal cord and brain spinal cord are broken, rather than pulling the head directly. This requires controlling the degree of force. Both the cervical spine and the head cannot be pulled off. Some of the students I brought before had problems with force. It directly caused the pressure inside the mouse's eyeball to be too high, and the eyeball even broke. "

Zheng Zhengtan: "..."

Nima is so scary!

Zheng Zheng sighed and looked at Dao Jiao's calm face when he said these words, and suddenly felt that Dao Jiao's eyes seemed to be cold.

Zheng Tan remembered the topics they had talked to when they had a nightclub with a group of wine and meat friends. At that time, one person said, "In fact, the most powerful killers are not those who look fierce on the outside, not those who wear a big knife tattoo and wear a nose ring posture. The people who are full are not those who use their swords all day to make themselves look terrific, but those who look nothing abnormal but can easily reap their lives in the next moment but still do not change their face. "

So some senior experimenters are similar to the killer temperament in some ways.

的 The experimenter who entered the experimental state is really horrible!

叹 Zheng Tan thought for a while, maybe Associate Professor Jiao was the only person in the world who taught his cat **** mice with the short neck method?

Zheng Tan obviously felt a lot better when he killed the third and fourth, at least making these two mice have a decent way of death compared to the previous two.

With five mice, Dao Jiao killed one for demonstration, and the other four were killed by Zheng Tan.

I cleaned up the five dead mice, and Dao Jiao turned to go to the back room again. He couldn't hold out a bigger cage, but there were still five white rats, but they were much bigger.

"This is a rat. The lab rat is an albino variant of the brown house rat. It still uses the same method as before, but it needs to be more vigorous. It is still a little bit. Find the essentials, control the strength, and hit it. I need to do it. Demonstrate? "

Zheng Zheng shook his head.

"Good boy."

Zheng Zhengtan: "..."

As Dao Jiao said, the rats were a little harder and a little bit more, but after five rats tried, Zheng Tan was also proficient.

"Do you still need to practice?" Dao Jiao asked.

Zheng Tan shook his head.

"Very good, let's stop here to kill rats, I'll tell you ..."

Zheng Zheng snarled his ears: "..." is here again.

Although the rats have been killed, it is clear that Dao Jiao's teaching status has not yet completely exited.

"In our laboratory, in addition to the cervical dislocation method commonly used to kill rats and mice, there are also methods such as decapitation, bloodletting, percussion, anesthesia, and gas poisoning. A needle is enough, hey ... I ’ll take a zoology and anatomy class to dissect a bullfrog next week, and I ’ll take one back to show you. Oh, and you should pay special attention to killing cats and dogs in the laboratory. Most of them are executed by air embolism. "After a pause, Dao Jiao looked at Zheng Tan and said," Do you understand this? "

叹 Zheng Tan shook his head, his muscles were a bit stiff, and the hair on his back and tail was still exploding. He always felt that the surrounding temperature was very low.

"In popular terms, this method is to inject air into the vein."

Zheng Zheng slammed a shock. I understand this ~ www.novelbuddy.com ~ Even if he doesn't have good knowledge in this aspect, he knows what happens when he blows air into the vein.

"Air enters the blood circulation to the lungs and blocks the pulmonary arteries, causing severe shock or death. For example, when you swim from deep water to a diving site, the pressure changes cause the lungs to swell, which in turn causes the lungs to over-expand. It ’s very dangerous not to exclude the excess gas or to have time to exclude it at all, which is why some passengers in the Titanic have fallen into the water. ”

Dao Jiao said that suddenly thinking of saying Titanic to a cat is useless, so he turned to the subject and made a summary. "So, you must pay attention to yourself and stay away from dangerous objects and pay attention to self-rescue."

After practicing the technique of killing rats, tonight's goal was achieved, Zheng Tan also had a spectrum in his heart. Although it is helpless to catch mice, but now that it is a cat, probably only cats that catch mice can be recognized. Even Ahuang's two goods can be caught. Zheng Tan believes he must be OK.

When Zheng returned to the courtyard of his family, Zheng Tan saw a familiar car with a military vehicle parked on the open side.

In this case, the fat guy also returned after finishing his relatives.

While Dad Jiao went to the parking shed to park, Zheng Tan jumped to the balcony on the first floor and looked inside.

袋 A bag of instant noodles was placed on the desk by the window, and a slight fat tabby cat was squatting on the instant noodles.
