At that time, Britain and the United States were fighting Nazi Germany. This new drug was very effective in controlling wound infections. By 1944, the supply of drugs was enough to treat all Allied soldiers who participated in the war during World War II. In 1945, Fleming, Flory and Chann won the Nobel Prize in Physiology or Medicine for "discovering penicillin and its clinical utility." Penicillin is an important antibiotic with high efficiency, low toxicity, and wide clinical application. Its development

Success has greatly enhanced human ability to resist bacterial infection and led to the birth of an antibiotic family. Its emergence has opened a new era of using antibiotics to treat diseases. 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, oleracillin, tetracycline, etc. have been continuously produced, enhancing human ability to treat infectious diseases.

But at the same time, the drug resistance of some bacteria is gradually increasing. In order to solve this problem, researchers are currently developing antibiotics with stronger efficacy, exploring how to prevent bacteria from obtaining resistance genes, and using plants as raw materials to develop antibacterial drugs.

It can be said that the emergence of penicillin greatly increased the body's resistance. At that time, penicillin was also known as a golden potion and was a country's strategic reserve substance, but even so, penicillin was not something that anyone could use.

The toxicity of penicillin antibiotics is very small and is the antibiotic with the largest chemotherapy index. However, the common allergic reactions of penicillin antibiotics rank first among various drugs, with a maximum incidence rate of up to 5% to 10%. They are skin reactions, manifestations of rashes, angioedema, and the most serious ones are allergic shock. They usually occur within a few minutes after injection. The symptoms are dyspnea, cyanosis, decreased blood pressure, coma, ankylosing limbs, and finally convulsions. Unrescue in time can cause death.

Various routes of administration or the use of various preparations can cause allergic shock, but the incidence of injection drugs is the highest. The occurrence of allergic reactions has nothing to do with the size of the drug. Those with high allergic reactions can also cause shock even if they are extremely slight. Injection into the body can cause epilepsy-like seizures. Large doses and long-term injections are toxic to the central nervous system (such as causing convulsions, coma, etc.). Stop the drug or lower the dose can be restored.

Penicillin is generally used to use injection, which can be fully absorbed. The aqueous solution of soluble crystalline penicillin salts is absorbed quickly, and the blood concentration can reach its peak within 15 to 30 minutes, while the absorption of procaine penicillin and oil penicillin is slower. Penicillin is mainly excreted in the body through the kidneys. Injection of water agents, the concentration of penicillin in the plasma is reduced by half within one hour. The skin, mucous membranes, etc. is also easy to absorb, and it is more likely to cause allergies than injections. Therefore, the administration route should be paid more attention to preventing allergic reactions. The use of skin tests greatly reduces the incidence of allergic, but it is often too large due to inaccurate amounts of skin tests, or the patient's own special sensitivity. Sometimes allergic reactions may occur during skin tests, so it is mainly clinically allergic reactions.

This is a very fatal allergy. In large urban hospitals, it may not be felt that it is necessary to do a test when injecting penicillin. Can it be injected? If it cannot be injected, it will be replaced with other drugs. However, in rural areas, there is no such condition. No matter what the disease is, doctors in general clinics will use penicillin.

Some people are not allergic, but more people have allergic reactions, so there are also medical accidents that hurt people.

Generally, at this time, the clinic must take the patients to a large hospital for examination. After the examination, it feels that there is no problem, so the matter can basically be over. After all, rural people will still be more simple. As long as they have no problems, they will not pursue other things at all. As for extorting money, it will not happen.

The reason for the things in front of you now is probably the same. The difference from others is that the clinic where the child goes to may have some background, so this happens when he wants to take his child to a large hospital for examination.

"The children are so healthy, so why are they checking everywhere? I think it's better to keep them at home, otherwise the more they 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 he should say!

"Nothing is this, that's it. It's one hundred yuan. Buy something for the child. It's over. If you go to cause trouble again, I'll be easy to talk to, and my brothers will not be so easy to talk to!" Zhang Cheng said lightly.

He didn't care at all about the rural people in front of him. Although he grew up in the countryside, he felt that he was nothing like the mud legs in front of him. He dared to do what he wanted to do. He dared to fight and fight, so he had everything he has now.

The mud legs in front of him would not resist no matter how threatened him. This was a feeling that made him enjoy it very much, making him seem to have become a big shot at all. He could do whatever he wanted to face everyone in front of him, and the other party could only choose to swallow his anger. This was the thing he enjoyed the most.

"Of course, our brothers finally came here once, and we couldn't get anything without gains. For this hundred yuan, we brothers took it to have tea. I don't think you would mind!"

It’s not that Zhang Chengda didn’t want to extort a few dollars before leaving, but as more and more people gathered around him, he was also worried that something would happen. Although rural people are easy to bully, they are not allowed to bully them at will, especially when there are more and more people.

Unlike urban people, the more people, the less likely it is to happen. Because they all have their own selfish intentions and are worried that if they take action, they will be treated as scapegoats and be framed by others, but they will fall into silence, so they end up silent.

But the countryside is different. Everyone belongs to the same village. They look down and see each other without looking up. Many people even have certain relatives. It is okay to say a few words to threaten them, but if they do it too much, they will cause public anger.

After all, they are all rural people, and they may encounter things that the other party can encounter. So this can easily arouse the other party’s anger. After all, he is not the person in charge of this village. If he is the village chief, he naturally doesn’t care about these people, but he is not.

So stopping when he is ready is what he wants to do. Anyway, the matter has been dealt with now. If it continues, maybe someone will stand out, and he is not afraid of someone standing out. After all, he is not only one person, but if someone stands out, then things will not end well.

Looking at the child's father who dared not speak out in front of him, Zhang Cheng said directly: "It seems that you have made up for it. You are cognitive, brothers, let's go!"

When he waved his hand and was about to take a group of people away, a cold voice suddenly came.

"What a great power, I ran to the other party's house and shouted that the other party could not live. Your Excellency is so great power!"

As the source of the sound looked, two figures, one big and one small, appeared in front of everyone. The big figure was burly and had an ordinary appearance, but she had a pair of glasses, and she felt a little kind.

The small figure, dressed in suitable clothes and handsome face, made him so out of place with the entire rural environment, like a graceful young man walking in the painting. Seeing this figure, everyone felt that he was lit up, such a beautiful young man.

Especially the little girl with a pale face, when she looked at the boy, she had a hint of spirit on her face. She struggled to walk down from the woman's arms, stumbled to the boy's side, and opened her hands to let the boy hug: "Brother Zero, hug..."

And the two of them were not others, so naturally they came over Wu Ling and Chen Changqing at the beginning. These things were indeed just small things. If they were in other places, they would not want to care about them at all. After all, there are too many unfair things in the world.

Almost every moment, every minute, every second, such unfair things happen. If you really have to worry about it, even if Wu Ling can transform into a million, he will not be able to do it. Besides, both of them are not so passionate people, and seeing such things in other places, you really may not be able to care about it.

But here is different. This is Chen Huifang's hometown, and his parents and relatives are here. Although the village is not too small and there are hundreds of people, the relationship between each person is not too bad, especially the little girl's house is not far from her grandmother's house, and she will occasionally take her to visit her. It can be said that they are not considered outsiders.

What's more, this matter is due to the little girl. Although Wu Ling hates being with naughty kids, the little girl is so close to him every time she sees him, so he naturally won't ignore it. Now that he has the ability, he should still take care of these things if he changes to them.

I have to say that Chen Changqing is still very capable, at least he understands the human heart, so Wu Ling's heart was just a slight move, and he had already seen Wu Ling's thoughts, so he stood up.

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

"Oh, there are really people who are not afraid of death, and come out!" Although it was a joke, Zhang Cheng's expression was even more fierce. He felt that the matter was over, but he didn't expect that someone who is not afraid of death came out. Isn't this slap him in the face?

"Who is not afraid of death? But I think I should not be afraid of you!" Although Wu Ling has to take care of the matter, Chen Changqing naturally would not think that it would be better to let Wu Ling come forward.

After all, no matter what, these are just very small things. If he can't handle these things, can he stay by his side as a waste? So, Chen Changqing stood up. (To be continued.)
