() The venom flows out of the viper's venom glands and collects along the walls of the cup to the bottom of the cup.

Liu Wei: "The detoxification amount of adult mountain vipers ranges from 150mg to 250mg, and the detoxification amount of this mountain viper in my hand is okay, around 210mg, it seems to be gone!"

Liu Wei pressed the head of the viper a little harder, and the viper began to retract its fangs, and the venom flowing on the wall of the cup decreased significantly.

The mountain viper was taken out of the cup, and the next experiment was a little dangerous, Liu Wei had to catch the auxiliary equipment and take out the intelligent snake control device provided by the system to control the mountain viper.

"Brothers, I need to be very careful in the next experiment, so I will put the viper aside for the time being, and everyone will focus on me!"

Liu Wei opened the nylon film on the poison cup, the skin tissue on his hand was intact, there was no wound, there was no need to worry about the venom entering the bloodstream through the wound, Liu Wei was also very careful to avoid his hand touching the venom remaining on the film.

"Look!"

He pulled the dagger from his waist and slid it lightly over his fingers.

"Damn, what are you going to do?"

"Do you want to test the poison?"

"Ah Wei, don't do anything stupid!"

"Streamer, you're crazy!"

Liu Wei smiled slightly, and dripped the blood from his fingers into the poison cup, in order to ensure that the effect was more obvious, Liu Wei also squeezed a few drops into the poison cup.

"Brothers, I am very careful with my movements now, there is some mountain viper venom left on the edge of the poison cup, I can't let the wound touch the venom, otherwise the venom will enter my bloodstream and cause harm to my body.

Well, that's pretty much enough!"

Liu Wei quickly picked up his fingers, sipped them with his mouth, then tore them off and pasted them on, and put on a white laboratory glove, which was left to him by Dennis at that time, to avoid contact with venom.

Liu Wei took the poison cup to focus on the lens, and shook it slightly, causing the venom of the mountain viper to merge with the blood dripping at the bottom of the cup.

Gradually, a chemical reaction was created.

The bottom of the cup forms a thicker red mixture.

Then it slowly condensed, like a piece of bloodstone.

What the audience sees in the camera at this time is that another small stone is shaking at the bottom of the poison cup.

"Damn, what's the situation?"

"It's amazing!"

"The knowledge points are coming, take out the notebook and memorize it!"

"I'm a little confused, what the hell is it, why does blood clot?"

Liu Wei smiled at the live broadcast with the coagulated blood: "Doesn't it feel incredible?" While I shook the cup, my heart was also timed, and the whole coagulation process was very fast, only six or seven seconds.

It's like magic.

Next, let me give you a good science about why human blood meets the venom of the mountain viper and causes blood clotting?

The venom of the mountain viper contains thrombin-like and thrombokinase-like enzymes, and the human coagulation mechanism includes endogenous and exogenous two categories, both of which eventually have a common pathway, that is, prothrombin is converted into thrombin under the action of prothrombin complex, and thrombin converts fibrinogen into fibrin monomers, thus exerting hemostatic function.

Thrombokinase in the venom of the mountain viper can promote platelet aggregation while activating endogenous pathways, while thrombin-like can directly increase the number of fibrin monomers and thus accelerate the coagulation response.

This simple experiment I did today is known in the West as 'diluting the mountain viper toxin time'.

At present, the mature procoagulant preparations used in clinical practice, such as batricotin and lizhi blood, are extracted from the venom secreted by the pit viper, which belongs to the same genus of blood vipers as the viper!

Got it, brothers!"

“??????”

"Anchor, can you speak human words?"

"I didn't understand a word!"

"Wait, is this Nima a popular science wildlife live broadcast or a popular science medicine live broadcast!"

"If I have no culture, I can only deduct a wave of 66666!"

Eternal Single sent Super Rocket × 1, "Well, what the anchor said makes sense!"

The reckless man sent the plane × 7, "The anchor is awesome and it's over!"

Liu Wei Judging from the barrage played by the audience, he didn't find anyone who understood, and it is estimated that the collective is in a state of confusion.

He smiled awkwardly and asked in a different way, "Brother who thinks it's amazing 1!"

“1111111”

The barrage of hundreds of thousands of people was collectively unanimous.

Liu Wei shook his head, thinking, it would be more appropriate to be direct.

"Alright, after this interesting experiment, let's move on to the topic of mountain viper venom!"

After Liu Wei'an finished processing the experimental equipment and picked up the smart snake controller, the mountain viper got a moment of rest, recovered his physical strength well, and began to wrap the snake controller hard.

It slowly realized that the harder it worked, the tighter the snake controller became, and after a few attempts, it relaxed its body and obediently wrapped its body lightly around the long pole of the snake controller.

"By the way, if you are obedient, you will suffer less!" , Liu Wei smiled and said, "Brothers, you may not understand the blood clotting mechanism you just talked about, let me tell you something that you can understand."

LD50 value, I shouldn't need to popularize science anymore, right?"

"Half lethal!"

"I'm already familiar with it!"

"If you don't know this, it's really not worth watching Awei's live broadcast, every time you encounter a poisonous snake, you will mention it!"

Liu Wei nodded with satisfaction, and made an OK gesture, "The mountain viper performed very well in the experiment of measuring half of the lethal amount, the LD50 of intravenous injection of mice was 0.08-0.31 μg/g, the intraperitoneal injection of LD50 was 0.40 μg/kg, and the subcutaneous injection was LD4.75/kg, which is a detailed data given by an expert, according to which it can be simply calculated that if you want to kill a person, only 40 to 70 mg is enough."

We just mentioned that the one-time detoxification amount of adult mountain viper is between 150mg and 250mg, that is, once bitten by an adult mountain viper is not treated in time, it will basically die.

The amount of poison excreted by a young snake can also achieve a lethal effect, so the inhabitants of India will consider it to be the culprit.

It is precisely because of the great harm it causes to the Indian people that India has also developed the antivenom of the mountain viper venom, which can effectively treat the poisoning phenomenon after being bitten by it. ”

"I suddenly feel that I am so perverted, I like to watch poisonous snakes very much, but I am very scared!"

"Laughing and crying, I'm like this too, I feel so exciting when I watch the live broadcast, and I have nightmares when I sleep at night!"

"Crooked day, I thought I was like this alone, hahahaha!"

"I'm fine, after all, I live in the city and haven't encountered a snake!"

"Yo, that's what you said, brother, is it a big city? Is the county still a metropolis?"

"The barrage has started to fight each other again!"

Liu Wei hurriedly persuaded, "Brothers, watch the live broadcast picture and have fun, whoever comes to the live broadcast room has the right to speak, don't care too much about a little thing, you usually scare me like that, I don't lack arms or legs, right? Be rational and happy to watch the live broadcast."

I just told you about the toxicity of the mountain viper, and there is another point that must be mentioned, that is, the toxin in the venom of the mountain viper, the venom of the mountain viper is a typical mixed toxin, and it has been found that there are as many as five toxins in the venom of the mountain viper!"
