Of course, poor medical students will definitely not afford expensive experimental animals, but they use ordinary experimental mice or domestic rabbits. The problem is that it is very small to do scientific research for students. How poor is it? The cost must be considered when meeting the experimental requirements. Rats can be used instead of mice, just because a mouse is a few more expensive than a rat, which can be slimly considered by poor scientific researchers. Not to mention domestic rabbits, it is much more expensive than mice.

When Wei, who may be able to afford Hermes stethoscope, heard this, he thought: This problem is not too big for me. Then I will ask my dad to pay some money to the teacher to help me buy more.

It's simple to think about it. Wei. This trouble is not just about the money you buy animals. You don't use it directly. Many experiments require animal models. Because you do clinical medical research and basic research on diseases, animals can use them to simulate a certain disease into a patient and facilitate research.

For example, during an internship in the obstetrics and gynecology department, Xie Wanying and Duan were fortunate to come into contact with some clinical research project documents. When teachers were studying gestational diabetes, they wanted to establish a rat gestational diabetes model in the laboratory.

How do you get this model? Either you buy it from the relevant model company. It is much more expensive than ordinary experimental mice. One can be thousands or tens of thousands of yuan. No matter how rich you have, it is difficult to afford such huge sums. Most of the time, researchers will try to model and raise sick mice by themselves. First, raise rats that meet the weight and age requirements of the experiment for two weeks, so that they can be familiar with the surrounding environment and diet to avoid external factors affecting the experimental process and results. Then, the male and female mice are mated. After pregnancy is confirmed, they are divided into control group and experimental group. The two groups of pregnant female mice are respectively injected with normal saline and streptozotocin into the abdominal cavity to induce diabetes of female mice.

As long as there is a little deviation between you, it will fail to meet the experimental ideas you set up, you can only rework them all.

Is it a problem of single money at this time? No. If you have money, you can't buy the experimental results. Some scientific research students and teachers are so irritable that they are under pressure to jump off a building and jump into the river because the results are not made as planned.

After explaining this to Wei, Student Xie can be considered the most common laboratory question answer.

Wei, who had not yet been in contact with scientific research, was stunned. Dai Nanhui once again questioned seriously: Are Xie’s parents really ordinary people?

"You say that, Yingying, the most important thing is-" Wei Shangquan asked.

Looking back, someone just questioned that their classmates, including her, Xie, are proud. Now it seems that on the contrary, Xie respects every tutor because he understands scientific research too much and respects every tutor. He does not want to cause trouble to his tutor, so he should make careful choices.

It is not in vain to avoid detours. Early experimental design is the most important thing, and this requires you to provide guidance with a tutor who has the same ideas. Therefore, Senior Sister Yu's words were the most correct at the beginning.

The surroundings were too quiet. Several students looked up and realized that their seniors had been eavesdropping on them at some point, and immediately put away their voices.

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

Not long after, Xie Wanying could feel the mysterious eyes of the fairy brother in front of her who had a profound look, and her heart was about to be beating.

This student Xie was really surprised. A person who seemed to have never been exposed to scientific research actually knows scientific research well. What's going on? The most outrageous thing is that many people probably knew about it before they told him. Don't blame a bunch of people for snatching it up.
