Chapter 511 Blood vessels disappeared?(2/2)
It's very popular. If you go there late, you won't be able to grab it, so you can only drink the most ordinary special alcohol Zhanlang milk.
It turns out that artificial blood vessels are too similar to natural blood vessels. After transplantation into mice, the mice's bodies accepted the material and regrown new tissue cells in the correct location.
It wasn't until my wife made a dissatisfied moan that she sat down on the sofa obediently.
"Polyurethane material has good elasticity and can resist thrombosis. It is not so rubbish, but it is not stable enough. It will degrade and calcify in the human body. If you dare to use it, you may die."
Existing artificial blood vessel manufacturers do not have a single business, but are large comprehensive medical enterprises that are used together with high-value consumables such as cardiac stents.
Before he finished speaking, he knew something was wrong. No matter what the mouse was, it was still an organic life form. With such a long artificial blood vessel, it would not be completely invisible.
However, when the intern showed up, he immediately became a little uneasy.
Wei Kang also likes the special food in the canteen very much, and gets his lunch there every day.
"Yeah." The smile on Wei Kang's face disappeared for a moment, and happiness continued to flow from the corners of his grinned mouth.
"Hey, I've been trying for so long and there's been no movement. I've long forgotten about it."
The medical student in charge was hurriedly found, a mouse was taken out, and it was killed by intravenous injection of high potassium.
On this day, Wei Kang got off work on time again and had just returned home.
"Since the implantation time in mice is still short, less than two weeks, it is not yet known whether the performance can be maintained stable in the body for a long time."
I counted them, there were six in total, and they were all fine. There was no problem at all, and I breathed a sigh of relief.
Therefore, Wei Kang deliberately renovated the basement and added a cold room for convenient food storage.
However, all this needed to be supported by facts. He quickly asked the medical students to take out the transplanted artificial blood vessels so that they could observe the internal structure and see if there were any changes.
A week ago, he asked the medical students of the project team to perform femoral artery artificial blood vessel transplantation on these mice.
"I didn't expect it to happen. I quickly went to the gynecology department for a check-up in the afternoon and it was officially confirmed."
Xue Shen sneered in his heart and dismissed the competing products from his friends: "When it comes to small-caliber artificial blood vessels, none of them can do it."
In addition, the farm has also sent a few ham pigs, and a few chickens every week.
This is because the time is too short and the artificial blood vessels have not been completely integrated with the tissue cells.
Sanqing Farm has also entered the harvest season.
When the transplant site was opened again, everyone was shocked by the scene that appeared in front of them.
"The preliminary conclusion is that the artificial blood vessel has good compatibility with the blood and tissue of mice, and has a self-healing ability similar to that of natural blood vessels, with good strength and no deformation."
"Commonly used polyester blood vessels can only be used for large-diameter blood vessel replacement surgeries and intravascular fistulas. Once used for small-caliber blood vessels, thrombosis will form within a short period of time after surgery."
"Could it be that it has grown together with the meat? There should be a difference. Why is it missing?"
Bang bang bang!
Everyone looked at the bloody artificial blood vessel on the experimental table and couldn't help but applaud.
He touched the transplanted femoral artery and found only a thick layer of muscle. When he pressed hard, the mouse immediately let out a squeaking scream.
It has become a real living blood vessel, it is strange that it can be touched.
It can be seen that the outside of the artificial blood vessel has been covered by new cells and tissues, wrapped layer by layer, and inseparable.
Jian Lian Yun was nestled in his arms, with a motherly smile on her face, talking about the day's experience.
The other is an artificial blood vessel fistula. A thicker artificial blood vessel is implanted in the arm to connect the artery and vein to facilitate hemodialysis. This is a life path for patients with renal failure.
My mind was in a mess, and thoughts kept flashing through me like a revolving lantern, and I couldn't control it at all.
"I have a child, parents, do you hear me?"
"The old Wei family has a daughter-in-law."
"What should I name my child?"
