Chapter 2535 【2535】Don't Have a Deep Meaning

Of course, ordinary poor medical students absolutely cannot afford expensive experimental animals, and they use ordinary experimental mice or rabbits. The problem is that the cost of doing scientific research for students is very small. No matter how poor it is, the cost must be considered under the premise of meeting the experimental requirements. Rats can be used instead of mice, just because a mouse is more expensive than a rat, so poor researchers can care about it. Not to mention domestic rabbits, they are much more expensive than mice.

Maybe Wei, who can afford the Hermès stethoscope, heard this and thought: This problem is not too big for me. Then I will ask my dad to send some money to the teacher to help me buy more.

Think simple. Classmate Wei. This trouble is not limited to money to buy animals. The animals you buy are not used directly, and many experiments require animal models. Because the basic research you do in clinical medical research is disease, animals have to be simulated as patients with a certain disease to facilitate research.

For example, during the internship in the Department of Obstetrics and Gynecology, Xie Wanying and Geng were fortunate to have access to some clinical research project documents. When the teachers were studying gestational diabetes, they had to establish rat models of gestational diabetes in the laboratory.

How did this model come about? Either buy it from a relevant model company, which is much more expensive than ordinary experimental mice, and one can cost tens of thousands. No matter how rich you are, it's hard to afford such a huge sum of money. Most of the time, researchers will try to model and raise sick mice by themselves. Firstly, the purchased rats whose body weight and age meet the experimental requirements were raised for two weeks to familiarize them with the surrounding environment and diet to prevent external factors from affecting the experimental process and results. Then the male and female mice were mated, and after pregnancy was confirmed, they were divided into control group and experimental group, and the pregnant female mice of the two groups were injected with normal saline and streptozotocin into the abdominal cavity to induce diabetes in the female mice.

As long as there is a slight deviation in the middle, which makes it unqualified and does not meet the experimental assumptions you set up, you can only redo it completely.

Is it just a question of money at this time? no. Money cannot buy experimental results. Some scientific research students and teachers are so irritable that they have the pressure to jump off the building because the results are not produced within the planned time.

After classmate Xie explained to classmate Wei in this way, it can be regarded as the most common answer to laboratory questions.

Wei's classmate Pan, who had never been in contact with scientific research, was taken aback when he heard this. Dai Nanhui once again seriously questioned: Are the parents of classmate Xie really ordinary people?

"You put it this way, Yingying, the most important thing is—" Wei Shangquan asked.

Looking back, some people questioned their classmates, including her classmate Xie, for their arrogance. Now it seems that on the contrary, Mr. Xie respects every tutor because he knows scientific research too well, and chooses carefully if he doesn't want to cause trouble for the tutor.

It is not in vain to avoid detours. The preliminary experimental design is the most important. This requires guidance from yourself and a mentor who finds the same thinking. So what Senior Sister Yu said at the beginning is the most correct.

It was too quiet around, and several students looked up and realized that the seniors were eavesdropping on them at some point, so they immediately silenced their voices.

Cheng Yuchen and Duan Sanbao looked at each other: the boss's expression and eyes were not quite right.

It didn't take long for Xie Wanying to feel a deep and meaningful glance from the godly elder brother's dark-bellied and beautiful eyes in front of her, which made her heart skip a beat.

This classmate Xie is really surprising. A person who seems to have no contact with scientific research actually knows a lot about scientific research. What's going on? The most outrageous thing is that many people should have known about it and didn't tell him. No wonder a bunch of people grabbed it.

Thank you for your support! ! ! good night dears~
