Chapter 242: Frog Heart Experiment in Tro Experiment
At this time, in the dust, a banana without skin flew over and smashed on Donkey Kong's head, falling into mashed bananas. Pen? Interesting? Pavilion wWw. biquge。 info
I burst out laughing.
Donkey Kong was too big for a banana to do him any harm, and he probably heard me laugh and turned his head to look at me. That blank look with a mashed banana on his head made me happy again.
However, I couldn't laugh for more than three seconds, and out of nowhere, a rooster sprang out of nowhere, and ran quickly in front of my eyes, leaving a cloud of chicken feathers and choking me to tears.
Lang Lang Qiankun, no one can laugh at others for a lifetime. Be a man and a demon must be low-key, maybe the next person to be ridiculed is himself.
I sighed helplessly and turned out of the paradise.
The skull was making breakfast, and that skillful movement was really pleasing to the eye. Of course, I wouldn't eat his breakfast. Since my husband left, I have not had the so-called three meals a day, at most I have an occasional glass of yogurt and a fruit.
Without the company of my husband, the food will always have less flavor, so it is better not to eat it.
"My lord, fruit salad, do you want to eat it?"
"Don't."
I shook my head.
Packed my things and went to class. Today there is a functional laboratory class, doing a perfusion experiment of isolated frog hearts, and I am quite interested. After the theory class, everyone put on their white coats and went to the laboratory.
The grouping of the laboratory class is divided by student number, and the group of six people is divided. There were 35 people in the class, and I happened to be number 35.
"Sister, I'm number 36, and we're in a group. Don't worry, sister, I've already previewed this experiment, and I won't hold you back. Ziyue said to me with a grin.
Twelve or thirteen-year-old Ziyue is about 1.7 meters tall, a head taller than me. Probably due to his relatively thin skin, the loose white coat looks a little fat on him.
But this did not affect his temperament in the slightest, but instead made him look like a brother next door who needed to be taken care of.
He is young and exquisite-looking, like a beautiful boy who came out of the comics, and no one can bear to blame him when they see him. Because of this, his classmates took good care of him. Even those classmates who initially thought he was "going through the back door" and "child's play" would not blatantly target him.
Now I look at him with a comfortable look, and I think he has adapted well to this week.
"Hmm." I responded to Ziyue lightly, lowered my head to play with my phone, waited for the teacher to come in, and occasionally listened to other students gossiping about today's experiment.
"Porridge, today I want to do an experiment on the heart of a frog in vitro. I'm a little excited about what's going on, haha. ”
"Have you read the book, first of all, I have to use something to destroy the bullfrog's spinal cord, I think I may be a little overwhelmed."
"The one next to the pool could not be today's test subject, right? It's kind of scary, it doesn't spew venom, does it? ”
"I'll go, it's really, it's disgusting......"
Hearing this, I also glanced at the basin by the pool. There were more than a dozen bullfrogs inside, all black and swarthy, with skin like a layer of blisters, and the pouches next to their gills bulged one after another, occasionally spurting out a little mucus.
The thought of holding it later gave me a chill.
At this time, the teacher also came in and explained some theoretical knowledge to us, and he began to show us how to destroy the spinal cord of a bullfrog.
I saw him put on gloves, grab a bullfrog in his left hand, and hold a stubby wire in his right hand.
"Attention students, when you destroy the spinal cord of the bullfrog later, you must find the right position. See? Hold it in this way, press its head down with your index finger, and something hard will stick out. Hold your hand against the wire like this, at this angle...... Which student would like to be the first to come up and try it? ”
The young teacher raised an eyebrow, as if he was happy to see us looking at each other and not daring to step forward.
With the encouragement of the teacher, a bold male classmate stepped forward to give it a try. When he grabbed the bullfrog, he gasped, and he didn't know what the bullfrog was feeling.
He tried to insert the stubby wire into the bullfrog's back, spinning the wire vigorously, but he still couldn't insert the wire, and a hideous expression began to appear on his face. Finally, the teacher corrected his movements, and he successfully inserted the wire into it, breaking the bullfrog's spinal cord.
At this time, the bullfrog's limbs are paralyzed, indicating that its spinal cord has been destroyed.
Then it's time for us to do our own experiments.
None of us in my group were reluctant to smash the bullfrog's spinal cord, so I put on my gloves and touched one of the bullfrogs.
Cold, slippery, cold-blooded animal, that's my first feeling.
"Sister, I'll come."
Ziyue couldn't help but take a bullfrog from the basin, he learned the teacher's movements, easily inserted the wire into the bullfrog's spinal cord, and after fiddling left and right, he saw that the bullfrog's limbs were paralyzed, so the first step of the experiment was considered successful.
Everyone else in the group was clapping, but I noticed that the moment Ziyue picked up the bullfrog, her temperament suddenly changed.
Indifference, slaughter, disregard for nothing.
It reminded me of the Ziyue I had seen that night.
"Sister, you, aren't you happy? Did Ziyue do something wrong? I shouldn't have ......"
"There's no upset and you haven't done anything wrong. I just remembered some old things, nothing. And then we started ......"
I didn't want to dwell on this issue anymore, so I moved on to the next step of the experiment.
I sensed Ziyue's frustration, but I didn't know what to say. He's been trying to "please" me for the past few days, but my mood hasn't changed because of this.
I was concentrating on the experiment, and I had no distractions.
I cut open the skin of the bullfrog, exposed its heart, ligated the nearby arteries and veins, and finally succeeded in isolating the frog's heart, fixing it to an iron bench and inserting a catheter.
At this point, I was relieved.
"Qin Yiren, you, you are so powerful!"
"yes, you see that the other groups have failed several times, and you succeeded in the first one, how did you do that?"
"Look, that heart is still beating!"
"It's amazing!"
……
The people in the group were very excited and chattered around me.
I wanted to finish the experiment in one go, but based on past experience, if I did it alone, the others wouldn't be happy. So let them do the rest of the experiments.
With the concerted efforts of several people, the experiment was a success.
There were two girls in the same group who took the experimental results to the other groups to "show off", and they were boasting about their "strength" in and out of their words. I just sat and watched them perform, waiting for the end of the lesson.
