"Smack!"

The used chalk was thrown onto the podium by the middle-aged man and broken in two. Pen "Fun" Pavilion www.biquge.info

Glancing around at the stunned classmates below, the middle-aged man raised his chin, "I'll give you two minutes to think, and in two minutes I'm going to draw someone to answer the question, but if anyone doesn't answer correctly, you will lose, now, start thinking!" ”

There was silence.

The students below all grew up, their mouths widened, their eyes widened, and their faces were full of disbelief.

A few people who were still drowsy, were poked and poked by the classmates next to them, and after figuring out the situation, they looked at the white chalk words on the blackboard and were full of surprise.

No one went to flip through a book or check their mobile phone, because this question was simply impossible to look up!

Everyone was eerily silent, two minutes seemed so long at this moment, everyone looked at each other, the students in the adjacent seats raised their eyebrows at each other, everyone thought the same.

The chalk on the podium reads: "Which way is more likely to cause insulin secretion, glucose injection, or oral glucose?" In other words, which situation produces more insulin? ”

This question doesn't need to be checked at first glance, anyway, it's like that if you don't check it or not, it's really ...... It's so easy!

Isn't the answer just a glance at it? Where do you need two minutes to think about it?

If you insist on what knowledge points are involved in this question, in addition to the role of insulin, it is estimated that it is the difference between oral and injection.

In pharmacology, drugs are absorbed by the body in both oral and injectable ways.

Oral, as the name suggests, is to take the drug through the mouth, and most of the people who usually take medicine are in this form.

One of the advantages of oral administration is that it is convenient and fast, usually prepare a little tablet or capsule and other drugs at home, and take it with warm water when needed.

There is also a disadvantage of oral administration, which is the "first-pass effect." ”

The first-pass effect, also known as the first-pass effect, refers to the phenomenon that when some drugs pass through the gastrointestinal tract, they are metabolized for various reasons before they have time to be absorbed into the blood circulation, so that the amount of drugs entering the body is reduced.

If you want to avoid or alleviate the first-pass effect, you can use injection, subcutaneous and sublingual administration.

Injection, as the name suggests, is to directly inject the drug into the blood circulation of the whole body through intravenous injection, which can not only avoid the first-pass effect, but also make the drug dose of the whole body reach a peak instantly, without waiting for the drug to be released slowly like oral administration.

There is a small detail in daily life that many people do not notice, when we take medicine orally, we often take more medicine, what two or three tablets at a time, three times a day or something.

But when we go for infusions, if we pay special attention to the nurse dispensing fluids, we may find that most of the fluids we infuse are normal saline, and the really useful drugs are actually just a little bit of liquid in a glass bottle smaller than the little thumb.

This is related to the first-pass effect, because the first-pass effect produced by oral administration will reduce the efficacy of the drug and reduce the absorption of the drug, so a larger amount of the drug needs to be given.

The difference between oral administration and injection is only the presence or absence of the first-pass effect and the time to produce the effect.

If the glucose solution is injected into the body, the blood sugar will rise instantly, and the corresponding response mechanism will be stimulated immediately, which will promote the production of insulin by pancreatic islets to lower blood sugar;

If it is taken orally, the glucose swallowed into the stomach has to wait for it to be absorbed, and wait until the blood sugar rises slowly, and then the body responds to lower the blood sugar.

So, the moment the middle-aged man finished writing the question, oh no, maybe in the process of writing the question, many people already had an unthinking answer in their minds.

As for why he deliberately wanted to wait for himself and others for two minutes?

Everyone looked left and right, saw a few sleepy-eyed and dazed-eyed, and finally knew the reason - the teacher wanted them to wake up these students who were not listening well in class!

Suddenly, everyone invariably carefully instructed their companions who had just woken up from a big dream.

Soon, the students' guesses were verified.

The middle-aged man said that the time was up, and decisively began to ask, "Come, squad leader, you can talk about it." ”

Jiang Yuan got up, "Inject glucose and insulin secretion more." ”

"Okay." The middle-aged man nodded, "Sit down." ”

"In the first row, count the third student on the left, you can answer."

Some of the dazed boys stood up, and his companion was desperately hinting at the side, he scratched his head, "Injection? ”

"Okay." The middle-aged man nodded again, the expression on his face did not change, and he called out again.

"The yellow-clothed classmate in the middle of the fourth row, yes, it's you, you can answer."

……

Except for the first one to ask, who was the head of the class, Jiang Yuan, the rest were all students who were drowsy in class just now, or who lowered their heads to play with their mobile phones!

According to the order from left to right, from front to back, the middle-aged man is not left behind, his memory is terrifying, and his ability to hold grudges is also terrifying......

When the guess was verified, everyone subconsciously breathed a sigh of relief, and at the same time reminded the students around them who were "focused on" to be sure to say the correct answer.

The students have already seen at this time that the purpose of the teacher's bet with everyone is to knock on these people who don't listen carefully to class, as for the so-called gambling contract, what to leave class early, according to his virtue of holding grudges, it is estimated that it is just talking.

But another condition, if someone answers such a simple question incorrectly, he may really delay the class!

Although it is impossible to say that it will drag on indefinitely, even if it only drags on for half an hour, it is terrifying enough for the students who already think that his class is tormented!

This is a glorious and great mission, this is a decisive moment related to the collective destiny, and this is the common expectation and vision of all the people used!

At this moment, this collective is working together for the same goal as never before.

"The ninth row, the one on the far right in red, yes, you can answer it too."

As the middle-aged man called up his classmates one by one, everyone finally understood the reason why he suddenly went crazy - there were too many people deserting in class!

So much so that they are ashamed!

"Eleventh row, the boy on the far right, you get up."

finally called Yang Tian, for some reason, everyone felt that the middle-aged man's tone seemed to be much gloomy.

Bad, bad things!

Everyone couldn't help but focus on the eleventh row.

Yang Tian had already stood up.

Just now, the little fat man had already called him out of the study of the system space, and he knew the current situation.

"Answer that question."

The middle-aged man pointed to the chalk writing on the podium.

"Hmm." Yang Tian nodded, "Oral." ”

"Okay, sit down." The middle-aged man waved his hand, but the next moment, his eyes suddenly widened, "Wait a minute, what did you say?" ”

"I said." Yang Tian paused, "I think that oral administration of glucose will secrete more insulin." ”
