Many viewers have completely lost control of their emotions.

In their lives, they have only ever been so close to cats and dogs.

Who would hang a snake around their neck for nothing, let alone a highly venomous snake? This snake is still very bad-tempered.

The new viewers at Station B felt that the anchor must be crazy, and fell into two emotions: confusion and shock.

Liu Wei looked at the barrage and smiled, "Brothers, don't get too excited. It's actually very gentle. I feel like I'm wearing a ribbon around it. I can feel the coolness on my neck. It's very comfortable under the current temperature. Why don't you try it? try?"

"roll!"

"roll!"

"Try a hammer!"

"I haven't found a wife yet!"

The audience looked disgusted.

Everyone knows that Liu Wei is joking, not to mention that there is no distribution of Western Cobra in China. A normal person will definitely not imitate Liu Wei and try such a fatal behavior.

"Hahaha, just kidding, I need to remind non-professionals not to imitate!" Liu Wei said with a smile, "The most important reason why I want to control its head is to show everyone its venom. , take a look at the reasons why this cobra boss ranks among the top ten deadliest snakes in the world!"

After speaking, Liu Wei took out a professional poison cup from his backpack.

Adjust live footage.

Focus!

Ensure that the audience can clearly see the moment when the western cobra bites.

The left hand holds the poison cup.

The right hand pressed a little harder on the head of the western cobra, and its upper and lower jaws staggered a little.

Just when Liu Wei brought its head to the mouth of the poison cup, it bit through the film and shook its head vigorously.

Liu Wei was tightly restrained.

Venom flows out of the transparent cup wall.

Western cobras don't excrete much venom at one time.

Liu Wei's palms could feel the intensity of its struggle, and it was indeed very uncomfortable.

"OK!"

Liu Wei used a little strength to remove the snake's head from the mouth of the cup.

Then he took out the smart snake controller provided by the system from his backpack and placed the Western Cobra on the snake controller, so that he would not have to worry about being attacked by the snake while educating the audience about venom.

Liu Wei shook the poison cup towards the sun and said with a satisfied smile, "Brothers, did you see it? We have obtained its venom.

Next it's my turn to prove it!

There should be a lot of venomous snake mysteries in the live broadcast room. If you have read relevant information about the world's venomous snake rankings, you will find a problem. There are differences in the top ten rankings of Western Cobras.

Some data show that the rankings are relatively high, some are relatively low, and some are exactly tenth! "

“I’ve seen some popular science about snakes, and it seems to be ranked tenth!”

"The Baidu Encyclopedia I looked at seems to be number eight!"

"I've seen one ranked sixth. It's too far forward. It doesn't feel reliable!"

As Liu Wei expected, the answers given by snake fans in the live broadcast room were inconsistent.

He popularized science: "When talking about the toxicity of venomous snake venom, let's first recall a common standard, the LD50 value, which is the half lethal dose.

I have mentioned this standard before and did not give you a detailed introduction to the measurement method of LD50 value. I will add it today.

We must be aware of the common sense that the venom of the same snake will vary due to many factors such as environment, gender, age, food intake, etc. Just like the venom in the poison cup in my hand, in such a harsh environment, the venom will The protein will be destroyed quickly, and the venom is not easy to store outdoors.

From this, we can deduce that LD50 will have different test results.

We all know that the common experimental subject is the white rat, and the default subject for toxicity experiments is the white rat.

There are four common injection modes, namely meridian injection, intraperitoneal gaze, intramuscular injection and subcutaneous injection. When comparing the toxicity of all venomous snakes, the comparison can only be made under the same injection mode. The currently recognized injection mode in the industry is subcutaneous injection because The closest thing to a real bite, a venomous snake's fangs bite through the muscle layer, releasing venom.

When I say it this way, you should be able to understand it! "

"OK! No problem!"

"Who are you looking down on? After all, you graduated from high school!"

"I can barely understand it!"

"Awei, just tell me!"

"Okay!" Liu Wei nodded, "After subcutaneous injection, the LD50 value obtained showed that the LD50 of Western Cobra was 0.473 mg/kg, ranking exactly tenth.

Therefore, the snake science videos you see on Station B are relatively professional, and I personally prefer the mainstream views in the industry. "

The audience unanimously responded with approval.

They believe in Liu Wei's professionalism.

Mainly the live science popularization, face-to-face contact with the Western Cobra, is several times better than the video and PPT science popularization, which reflects Liu Wei's professionalism.

Liu Wei looked back at the Western cobra wrapped around the snake control device. He lost his temper and gradually calmed down.

He turned around and said: "After talking about the rankings, let's talk about the harm caused by the venom of the western cobra to the human body. Everyone, listen carefully, maybe it can be used in times of crisis.

When the western cobra launches an attack, it has a habit of not expelling its venom all at once. It should be said that many venomous snakes in the subfamily Cobra subfamily will hold back and wait and see what happens.

When it bites the body, only half the amount of venom is injected into the body, which means the other half may be its saliva or bacteria in the mouth. "

"Hahaha, saliva, I'm laughing so hard!"

"I'm not afraid of saliva, I have it too!"

"Come on, cobra, let's spit at each other!"

"The anchor's description was so funny, it made me laugh to death!"

"The effect of the show, the effect of the show!" Liu Wei smiled and then said seriously, "So the power of the wound is lighter than that of many other venomous snake bites.

But everyone must not take it lightly, pay attention to it and receive treatment as soon as possible.

As we have said, venomous snakes in the family Cobraidae are basically venomous snakes with front groove teeth. The amount of poison they excrete is smaller than that of venomous snakes. The toxins in their venom are mainly neurotoxins. The same is true for the venom of Western Cobra venom, which also contains a certain amount of cardiotoxins.

But the most terrifying thing about its venom is that the venom injected into the body will cause symptoms of coagulation loss.

Coagulation function refers to the ability to change blood from a flowing state to a gel state that cannot flow. In essence, it is the function of converting soluble fibrinogen in plasma into insoluble fibrin.

This is also the main reason why the Western Cobra is classified as a deadly venomous snake. Once the victim develops abnormal coagulation function, the mortality rate is very high.

In addition, after being bitten by a western cobra, abdominal pain, breathing difficulties, dysphagia, spasm, eyelid ptosis, hemolytic reaction, myocardial tightness, etc. may occur.

These are common symptoms after being bitten by a cobra. Remember, you must treat it in time! "

“Understand, understand!”

"Remember it, remember it!"

"In short, just call 120!"
