Britain and the United States were at war with Nazi Germany. This new drug is very effective in controlling wound infections. By 1944, the supply of medicine was sufficient to treat all Allied soldiers who fought during the Second World War. In 1945, Fleming, Flory, and Chin were jointly awarded the Nobel Prize in Physiology or Medicine for "the discovery of penicillin and its clinical utility." Penicillin is an important antibiotic with high efficiency, low toxicity and wide clinical application. Its successful development has greatly enhanced the ability of human beings to resist bacterial infections, and led to the birth of the antibiotic family. Its emergence ushered in a new era in the treatment of diseases with antibiotics. Through decades of improvement, penicillin injections and oral penicillin have been able to treat pneumonia, tuberculosis, meningitis, endocarditis, diphtheria, anthrax and other diseases, respectively. After penicillin, antibiotics such as streptomycin, chloramphenicol, oxytetracycline, and tetracycline have been produced, enhancing the ability of humans to treat infectious diseases.

But at the same time, the resistance of some germs is gradually increasing. To solve this problem, researchers are currently developing more potent antibiotics, exploring how to prevent pathogens from acquiring resistance genes, and developing antimicrobial drugs from plants.

It can be said that because of the appearance of penicillin, the body's resistance has been greatly increased. At that time, penicillin was also known as the golden potion and was a country's strategic reserve substance, but even so, penicillin was not available to everyone.

Penicillin antibiotics have a small toxicity and are the antibiotics with the largest chemotherapy index. However, the common allergic reactions of penicillin antibiotics rank first among various drugs, with an incidence of up to 5%~10%, which is a skin reaction, showing rash, angioedema, and the most serious case is anaphylactic shock, which occurs within a few minutes after injection, and the symptoms are dyspnea, cyanosis, blood pressure drop, coma, limb rigidity, and finally convulsions, and death can be caused if the rescue is not timely.

Various routes of administration or the application of various preparations can cause anaphylactic shock, but the incidence of injectable drugs is the highest. The occurrence of allergic reactions is independent of the size of the drug dose. People who are highly allergic to this product can cause shock even in very small amounts. Injection into the body can cause epileptiform seizures. High-dose prolonged injections are toxic to the central nervous system (eg, causing convulsions, coma, etc.), and can be recovered by stopping the drug or reducing the dose.

Penicillin is generally used by injection and can be fully absorbed. The aqueous solution of soluble crystalline penicillin salts is absorbed quickly, and the blood concentration can reach the peak within 15~30 minutes, while the absorption of procaine penicillin and oil penicillin is slower. Penicillin is excreted in the body mainly by the kidneys. In those who are injected with water, the concentration of penicillin in the plasma drops by half within an hour. It is also easily absorbed by the skin and mucous membranes, and it is more likely to cause allergies than injections, so it is necessary to pay more attention to preventing allergic reactions to the route of administration. The incidence of allergies is greatly reduced by skin test, but it is often caused by excessive dosage of skin test, or the special sensitivity of the patient itself, and sometimes allergies can occur due to skin test, so it is mainly allergic reaction in clinical practice.

This is a very fatal allergy, which may not be felt in a large city hospital, because when injecting penicillin, you must have to do a test, whether you can inject it, and if you can't inject it, you will change to other drugs. But in rural areas, this condition is not available, and no matter what kind of illness it is, the average clinic doctor will use penicillin.

Some people are not allergic, but more people will have allergic reactions, so there has been a medical accident that hurts people.

At this time, the clinic must take the patient to the big hospital for a check-up, and after the examination, if there is no problem, then the matter can basically be over. After all, rural people will still be a little more simple, as long as they have no problems, they will not pursue other things at all. As for going to blackmail money and the like, it won't appear.

And the reason for the current thing in front of me is probably the same, but unlike others, the clinic that the child goes to may have some background, so when I want to take the child to a big hospital for examination, such a thing will appear.

"The children are so healthy, and they are still checking everywhere. I see, it's better to keep it at home, otherwise the more you check, the more things will happen! Zhang Cheng said with a little threat.

"This ......" Looking at Zhang Cheng's expression and the group of young people behind him who were eager to try, the child's father didn't know what to say!

"It's nothing, that, it's a hundred dollars, buy something for the kids. That's the end of the matter, if you go to trouble again, I'm easy to talk to, but my brothers aren't so talkative! Zhang Cheng said lightly.

He didn't care at all about the rural people in front of him. Although he also grew up in the countryside, he felt that he was no different from these mud legs in front of him, and he dared to do what he wanted to do. Dare to fight, that's why we have everything now.

And the mud-legged people in front of him, no matter how he threatened, the other party would not resist. This is a feeling that he enjoys very much, making himself seem to have become a big man all of a sudden, in front of everyone in front of him, he can do whatever he wants, and the other party can only choose to swallow his anger, which is what he enjoys the most.

"Of course, our brothers finally came here once, and they can't do without gain, this hundred yuan, a few of our brothers will take it to drink tea, I don't think you mind!"

It's not that Zhang Chengzhi doesn't want to just ask for a few dollars before leaving, but as the people around him gather more and more, he is also worried that something will happen. Although rural people are easy to bully, they are not something that can be bullied casually, especially when there are more and more people.

Unlike city people, the more people there are, the less likely it is that anything will happen. Because they all have their own selfishness, they are worried that if they make a move, they will be used as a scapegoat and framed, but they will fall into it, so they finally fell silent.

But the countryside is different, everyone is a village, look down and don't look up, and even many people have a certain kinship, just say a few words and threaten it, but if you really go too far, it will provoke public anger.

After all, they are all rural people, and what the other party can encounter, they may also encounter. So this is easy to provoke the anger of the other party, after all, he is not the person in charge of this village, if he is the village head, he naturally doesn't care about these people, but he is not.

So accepting it when he sees it is good, is what he has to do, anyway, now that the matter has been dealt with. If it continues, maybe someone will come out, and he is not afraid of someone coming out, after all, he is not the only one, but if someone comes out, then the matter will not end well.

Looking at the child's father who dared to be angry in front of him, Zhang Cheng said directly: "It seems that you have acquiesced." Count you as acquaintances, brothers, let's go! ”

With a wave of his hand, he was about to lead a group of people away, when a cold voice suddenly came.

"It's so majestic, run to the other party's house and shout so that the other party has no way to live, Your Excellency is so majestic!"

Looking at the source of the voice, two figures, one large and one small, appeared in front of everyone. The big figure is burly, and although his face is ordinary, he wears a pair of glasses and has a sense of kindness.

And the small figure, a suitable costume, and a handsome face make him so incompatible with the entire rural environment, just like a beautiful young man walking in the painting. Seeing this figure, everyone felt that the front of them was bright, what a beautiful boy.

Especially the little girl with a little pale face, when she looked at the teenager, her face also had a little more look. Struggling to get out of the woman's arms, he stumbled to the young man's side, and opened his hand to let the young man hug: "Brother Zero, hug ......"

And the two are no one else, naturally Wu Ling and Chen Changqing, who came over at the beginning. These things are indeed just small things, if they were somewhere else, the two of them didn't want to care about it at all, after all, there are too many unfair things in the world.

Almost every moment, every moment, every minute, every second, such injustices happen. If you really want to take care of it, Wu Ling can't do it even if he can turn into a million. Besides, neither of them is such a hot-blooded person, and when they see this kind of thing in other places, they really don't necessarily care.

But this is different, this is Chen Huifang's hometown, and her parents and relatives are here. Although the village is not too small, there are hundreds of people, but the relationship between everyone is not too bad, especially the little girl's home is not far from her grandmother's house, and occasionally she will take them to visit the door, so to speak, they are not outsiders.

What's more, this matter is still because of the little girl. Although Wu Ling hates being with bear children, the little girl is so close every time she sees him, so he naturally won't ignore it. Now that we have the strength, we should still manage these things.

I have to say that Chen Changqing is still very capable, at least he understands people's hearts, so Wu Ling's heart only moved slightly, and he had already seen Wu Ling's thoughts, so he spoke up.

When Wu Ling picked up the little girl, Zhang Cheng also turned around.

"Yo, there are really people who are not afraid of death coming out!" Although it was a joking expression, Zhang Cheng's expression was even more fierce. He felt that the matter was over, but he didn't expect another person who was not afraid of death to come out, didn't this slap him in the face!

"Who is afraid of death, but I think I should not be afraid of you!" Although Wu Ling has to take care of the matter, at this time, Chen Changqing naturally does not feel that it is better to let Wu Ling come forward.

After all, these are just tiny, tiny things, anyway. If he can't handle these things, then stay by his side as a waste? Therefore, Chen Changqing stood up. (To be continued.) )
