Of course, poor medical students cannot afford expensive experimental animals, so they use ordinary laboratory rats or rabbits. The problem is that the cost of scientific research for students is very low. No matter how poor they are, they will definitely consider the cost under the premise of meeting the experimental requirements. They can use rats instead of mice, but the fact that a mouse is a few yuan more expensive than a rat can be a big deal for poor researchers. Not to mention rabbits, which are much more expensive than mice.
Wei, a student who could probably afford a Hermès stethoscope, heard this and thought: This is not a big problem for me. I will ask my dad to give some money to the teacher to buy me more.
I think it's too simple. Mr. Wei, this trouble is not just the money for buying animals. You don't buy animals for direct use. Many experiments require animal models. Because clinical medical research is basically about studying diseases, animals must be given some kind of disease to simulate patients for easy research.
For example, when Xie Wanying and Geng were interning in the Department of Obstetrics and Gynecology, they had the opportunity to come into contact with some clinical research project documents. When the teachers were studying gestational diabetes, they had to establish a rat gestational diabetes model in the laboratory.
How do you get this model? You can either buy it from a model company, which is much more expensive than ordinary laboratory mice, and can cost thousands or even tens of thousands of yuan. No matter how rich you are, it is difficult to afford such a huge amount of money. Most of the time, researchers will try to model and raise sick mice themselves. First, buy rats that meet the experimental requirements of weight and age to raise them for two weeks to let them get familiar with the surrounding environment and diet to avoid external factors affecting the experimental process and results. Then, the male and female mice are inseminated, and after confirming pregnancy, they are divided into a control group and an experimental group. Physiological saline and streptozotocin are injected into the abdominal cavity of the two groups of pregnant female mice to induce diabetes in the female mice.
If there is just a slight deviation in the process that causes the product to fail and not meet the experimental plan you set, you will have to redo the entire process.
Is it just a matter of money? No. Money cannot buy experimental results. Some scientific research students and teachers are so angry that they feel like jumping off a building or jumping into a river because their results are not produced as planned.
Xie’s explanation to Wei is probably the most common answer to a laboratory problem.
Wei and Pan, who had never been involved in scientific research, were stunned. Dai Nanhui once again seriously questioned: Are Xie's parents really ordinary people?
...
...
"You said so, Yingying, the most important thing is--" Wei Shangquan asked.
Back to the question of whether this group of students, including Xie, were arrogant because of their talent. Now it seems that on the contrary, Xie is too knowledgeable about scientific research and respects every supervisor. She does not want to cause trouble for the supervisor and chooses carefully.
If you want to avoid detours and not waste your efforts, the early experimental design is the most important, and this requires guidance from yourself and a mentor who shares the same ideas. So what Sister Yu said at the beginning was the most correct.
It was so quiet around them that a few students looked up and realized that their seniors had been eavesdropping on their conversation, so they immediately lowered their voices.
Cheng Yuchen and Duan Sanbao exchanged glances: there was something wrong with their boss’s expression and eyes.
Before long, Xie Wanying could feel the far-sighted and sinister eyes of the fairy brother in front of her shooting a meaningful glance at her, which was enough to make her heart beat fast.
This student Xie is really surprising. He seems to have no experience in scientific research, but he knows a lot about it. What's going on? The most outrageous thing is that many people should have known about it before but didn't tell him. No wonder so many people are scrambling for it.
