Experimental animals are like this, divided into disposable and non-disposable. Disposable is easy to understand. It is like taking an anatomy class in an anatomy room. The animal is caught and placed on the operating table for dissection and observation. After the dissection, the animal has no other use.
It will be treated humanely in a timely manner. Most experiments are non-disposable experimental animals. After performing some experimental operations on the experimental animals, they will be placed in cages and continued to be raised and observed. When the time comes, they will be dissected and observed to obtain the experimental results before humane treatment.
, provide data support for experimental papers.
Several students stood in front of the cage and observed the mice raised by Classmate Duan, and they all guessed what kind of experiment Duan was conducting.
"There doesn't seem to be anything unusual." Student Wei frowned and said.
Student Wei's observation skills are obviously impressionistic. He believes that it is normal for mice to be alive and move around.
"Why do you have eyes?" Pan Shihua couldn't help but talk about his careless roommate, "Didn't you see the sutures of the surgical incisions on their abdomen?"
"Abdominal surgery? Isn't it cardiac surgery? Isn't he a cardiac surgeon?" Wei asked curiously.
"Is it studying abdominal aortic aneurysm?" Dai Nanhui considered.
"Abdominal heterotopic heart transplantation."
The last words came from classmate Xie.
The other students looked at her, and then at Classmate Duan's expression: It seems right.
What is intra-abdominal heterotopic heart transplantation? We have talked about heterotopic heart transplantation before in heart transplantation, which is relative to orthotopic heart transplantation. Let me repeat briefly: the original heart of the recipient is not taken away
, install another heart elsewhere in the recipient's body. Heterotopic heart transplantation is preceded by the word "abdominal cavity" to indicate that the new heart installation site is located in the recipient's abdominal cavity.
In experimental animal models, in addition to the abdominal cavity, heterotopic heart transplantation can be performed in any location that the experimenter can think of. In addition, common heterotopic transplantation sites include the neck and rarely the groin area.
The abdominal cavity is the most common and is the origin of this heterotopic heart transplantation experiment. The experimenters first used rats as experimental animals. Later, they gradually developed into other experimental animals such as mice and rabbits. Now Duan is doing it in small children.
In the case of rats and rabbits, it seems that we have the confidence to conduct further experimental explorations with the expenditure of scientific research funds.
Experimental animal heart transplant experiments are done to serve human medicine. Human medical heart transplantation is allogeneic between the donor and recipient. Experimental animals are benchmarked the same, and allogeneic donors and recipients must be selected.
Seeing this, it is easy to understand what the main research of this experiment is. It can simply study the risks of this surgery, or it can also study the pathological changes of the recipient and donor heart after transplantation, mainly the occurrence of various postoperative complications.
Mechanisms and solutions.
"Isn't Mr. Cao not interested in heart transplantation? Are you doing research on heart transplantation with him?" Several students were a little confused when they learned Duan's answer. Duan studied under the immortal brother, but what he studied was not the immortal brother.
Isn't he a new traitor if he is interested? Maybe he should have been secretly working next door, Dr. Mu Yongxian, who was most interested in heart transplantation.
Duan Sanbao, who was questioned by others, opened her eyes wide: What?
"What they are doing is not a heart transplant experiment." Duan Sanbao, who was deeply incredulous, revealed the research secrets of another scientific research leader.
