    Of course, the average poor medical student cannot afford expensive experimental animals, so they use ordinary laboratory mice or rabbits.  The problem is, the cost for students to do scientific research is very small.  No matter how poor you are, you must consider the cost under the premise of meeting the experimental requirements. Rats can be used instead of mice. Just because a mouse costs a few dollars more than a rat, the poor researchers will be forced to worry about it.  Not to mention domestic rabbits, which are much more expensive than mice.

    When classmate Wei, who may be able to afford a Herm¨¨s stethoscope, heard this, he thought: This is not a big problem for me. I will ask my dad to give the teacher some money to buy more for me.

    Think it¡¯s simple.  Classmate Wei.  The problem goes beyond just paying for the animals.  The animals you buy are not used directly. Many experiments require animal models.  Because when you do clinical medical research, you basically study diseases. Animals must be brought with certain diseases to simulate patients to facilitate research.

    For example, when they were interning in the Department of Obstetrics and Gynecology, Xie Wanying and Duan were fortunate enough 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.

    Where did this model come from?  Either buy them from relevant model companies. They are much more expensive than ordinary laboratory rats, and can cost several thousand or more each.  No matter how rich you are, it's hard to afford such a huge sum of money.  Most of the time, researchers will try their own modeling to raise sick mice.  First, buy rats that meet the experimental requirements for weight and age and raise them 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 the pregnancy was confirmed, they were divided into a control group and an experimental group. Normal saline and streptozotocin were injected into the abdominal cavity of the two groups of pregnant female mice to induce diabetes in the female mice.

    As long as there is a slight deviation among you that leads to disqualification and does not meet the experimental assumptions you set, you can only redo it completely.

    Is it just a matter of money at this time?  no.  Money cannot buy experimental results.  Some scientific research students and teachers were so irritable that they felt pressure to jump off buildings and rivers because their results were not produced as planned.

    Xie Xie explained to the most common laboratory questions to explain to Mr. Wei.

    Classmate Wei and classmate Pan, who had never been exposed to scientific research, were stunned for a while.  Dai Nanhui once again seriously questioned: Are the parents of this classmate Xie really ordinary people?

    "You said so, Yingying, the most important thing is-" Wei Shangquan asked.

    Looking back, someone just questioned the fact that her classmates, including her classmate Xie, were proud of their talents.  Now it seems that on the contrary, Mr. Xie respects every tutor because he knows too much about scientific research. He does not want to cause trouble to the tutor and must choose carefully.

    If you want to avoid detours and not waste your efforts, the early experimental design is the most important. This requires guidance from yourself and a mentor who has the same ideas.  So what Senior Sister Yu said at the beginning was the most correct.

    The surroundings were too quiet. Several students looked up and were surprised to realize that their seniors had eavesdropped on them at some point. They immediately stopped talking.

    Cheng Yuchen and Duan Sanbao looked at each other: their boss¡¯s expressions and eyes looked wrong.

    Not long after, Xie Wanying could feel the foresighted and dark eyes of the fairy brother in front of her sending a meaningful glance, which made her heart skip a beat.

    ¡°This student Xie is really surprising. A person who seems to have never been exposed to 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 before but didn't tell him.  No wonder a bunch of people grabbed it.  (Remember the website address: www.hlnovel.com
