All Zhang Ran's knowledge of penicillin comes from the Internet.

In addition to the introduction of penicillin on Du Niang's entry, there are more interesting anecdotes about penicillin, which are not helpful at all for the detachment to prepare penicillin.

Moreover, even the things about penicillin on Du Niang's entry, he almost forgot it, and only remembered that the fundamental reason why the development of penicillin was so tortuous was that it was not easy to extract penicillin strains, and it was even more difficult to cultivate.

For a long period of time, the culture of penicillin bacteria per unit was only 10,000 or 20,000 units, and for wound treatment, the dosage of a single dose was 6 or 700,000 units, so it was impossible to achieve mass production.

The breakthrough came from the discovery of a large number of penicillin plaque from the melon shell by a scientist, and the successful use of corn flour to prepare a nutrient solution suitable for cultivating penicillin, which made a generation of antibacterial miracle drugs really enter the clinical stage, and as an irreplaceable antibacterial drug since its discovery, it has saved countless lives.

These are all that Zhang Ran still remembers about penicillin, and all that Zhang Ran told Han Jinshan.

Han Jinshan's secret penicillin laboratory was set up in the hospital.

Because of the requirements of the hospital for the environment, of course, it is impossible to set up in the village, after all, there are not only chicken farms but also rabbit farms in the village, and there are many kinds of germs.

The hospital is located in the east of the village, it is the best building in the whole base area, it is more luxurious than the team headquarters of the detachment, all the blue brick houses, and the roof is also equipped with a wooden attic, which can be insulated in winter and in summer, and the hospital also has those health team members who take care of them meticulously......

Now, as long as the soldiers of the detachment are not fatally injured and go to the hospital, they are all in a mess, and they feel that they are going to enjoy themselves.

Zhang Ran and Han Jinshan craned their necks through the village in the cold wind and headed towards the hospital.

Black smoke is rising from the coking plant and copper smelter, and villagers who have returned from transporting coal from Dongjiang County are constantly passing by the village with their backs and so on, heading in the direction of the coking plant, steaming hot all over their bodies, like steamed buns that have just come out of the cage.

The existence of these makes the cold winter season in this bleak base full of vitality.

"Captain Zhang is good, Dean Han is good ......"

Seeing Zhang Ran and Han Jinshan, the villagers who came in with coal on their backs or left with empty backs greeted each other happily, although there were still beads of sweat on their foreheads.

At this time in previous years, most of them were confined to the cat winter at home, but now, although they are busy all day and night in this cold winter, at the end of the day, they are tired of backache.

But even so, they all have happy smiles on their faces, which comes out of their hearts, not pretending!

Because in previous years, although they were not as tired as they are now, the feeling of sitting and eating the sky, the feeling of staying up hungry, was extremely tormenting!

Now it's different!

Although tired, but to help the detachment to work to transport coal and build roads, that is all work, when the crops need to be fertilized, you can use these points to exchange for the precious fertilizer, so that the field can produce more food!

Not to mention, the detachment is still in charge of a meal!

It's not the kind of gruel that coaxes the belly, but dry rice, and chicken soup to drink the next day, which is better than what you eat at home!

So, helping the detachment work, the big guy is happy in his heart!

It's not just because of the change of labor for fertilizer and not just the ability to eat a good meal for nothing, but more importantly, because of the hope that the days will get better and better!

And all of this was brought to them by Zhang Ran.

So when they saw Zhang Ran and greeted Zhang Ran, their tone was extremely intimate.

"It's all good, it's all good, it's hard work!"

Zhang Ran smiled kindly, greeted the busy villagers, and then followed Han Jinshan into the hospital laboratory.

A fireplace was built outside the laboratory, and coke was burned inside, and the hot gas generated was used to warm the laboratory, artificially creating an environment suitable for the growth of fungi.

As soon as the door was opened, there was a hot air in my face, like a warm spring.

Suddenly, an electric light came on.

The cultivation of fungi requires not only temperature, but also a certain amount of light, and now that it is winter, it is impossible to take the petri dish outside.

It just so happened that the experiment with the grinding wheel had to be suspended due to glue problems, so the motorcycle engine was temporarily lent here for the purpose of using it as a motor to increase the light of the penicillin bacteria cultivated in the laboratory for two hours a day.

The wattage of the bulb was not high, and the brightness was slightly insufficient, but after all, everything in the laboratory appeared in Zhang Ran's eyes.

The local law is on the horse, and it is definitely worthy of its name.

It's all home!

Even the petri dishes were cut apart from glass bottles and placed on wooden shelves one by one.

There was a strange smell in the air, and Zhang Ran sniffled and came to one of the petri dishes with a slight turquoise color, and the strange smell emanated from this petri dish......

"Captain, you said this, is it penicillin?" Han Jinshan asked uncertainly.

Zhang Ran sniffled and looked at the blue-green thing floating on the petri dish, and said with an uncertain expression: "Why do I think it's rancid?" When you collected the plaque, did you not clean it? ”

"All the collection is the blue-green plaque you said captain, I bleached the impurities with water!"

Although Han Jinshan was not sure if there was a problem with him, his tone had already explained that all his things were done in strict accordance with Zhang Ran's explanation!

After letting go, the two could only scratch their ears and cheeks.

After a while, Zhang Ran said: "Why don't we use stupid methods?" Looking for some dogs to try? ”

“……”

Han Jinshan said depressedly: "The villagers don't give me dogs anymore, they say that giving the dog to me is more evil than directly killing and eating meat, and it hurts the heavens and ......."

"What are these words? You are conducting medical experiments, saving the lives of our brave soldiers, and benefiting the common people—how can you say that it hurts the heavens and reason! ”

Zhang Ran was annoyed, but since Han Jinshan couldn't get it, he estimated that it would be useless for him to go out to find the villagers to ask for a dog.

It's hard for the villagers to refuse themselves, but the villagers will say no.

Yes, don't give it, Zhang Ran has something to say.

But people say no, even if Zhang Ran shakes the official authority of the only detachment leader in the base area, it is useless!

"You use dogs for experiments, I guess only the folks around our old base area know, right?"

Zhang Ran thought for a while: "Let's not look for a dog in the area of the old base - I asked Secretary Wang and Director Lu to look for it in a farther place, but I don't believe that I can't find it!" ”

"Uh-huh-hmm......"

Hearing this, Han Jinshan showed a crazy smile like a lamb doctor and said, "As long as there is a dog, I can try it in a stupid way - as long as the penicillin you said by the captain really works, then I can try it sooner or later!" ”

I just don't know how many dogs have to die......

Zhang Ran silently said what Han Jinshan had not finished speaking, and at the same time mourned in his heart for those dogs who were about to be murdered, and at the same time he was glad that people in this era were not full of food, and they did not care too much about the life and death of canine creatures.

Otherwise, with this behavior of himself and Han Jinshan, Zhang Ran is sure that the two of them will definitely be sprayed by dog lovers to the point that they can't take care of themselves, even if the windows at home are made of titanium alloy, they can't bear it!

Although he didn't have to worry about being troubled by the Holy Mother, in order to save Han Jinshan from taking some detours in the process of cruel experiments, Zhang Ran still put forward some suggestions on the experiment.

For example, no matter whether the blue-green substance in the petri dish is plaque containing penicillin bacteria, or really spoiled mold, it cannot be simply and rudely wiped directly on the wound, and must be separated and purified before use.

Of course, Zhang Ran couldn't say why he should separate and purify the method, so he could only let Han Jinshan explore it himself.

This kind of work inspection that does not understand anything, and cannot even pretend to understand it, is destined to not last long.

After communicating with Han Jinshan about all the extremely limited things he knew, Zhang Ran instructed Han Jinshan with a solemn expression: "Come on, I believe you will be able to get penicillin out!" ”

Han Jinshan nodded with a heavy responsibility on his shoulders, saying that he would do his best and hope to live up to his mission!

"Han Jinshan, this comrade is good!"

came out of the hospital and found that Zhang Ran, who was not ridiculed by Han Jinshan for the first time because he didn't understand it very well, was happy, and silently remembered Han Jinshan in his heart - he was sure that if it was Deng Fang, he would be teased by the other party and he wouldn't even be in the mood to eat dinner!

"Brother Ran......"

The crisp voice came, and the annoying Deng Fang did not appear, but Deng Fang's likable daughter appeared in front of Zhang Ran.

"Teacher Deng, didn't you have class today?" Zhang Ran asked with a smile.

"It's winter vacation now!"

Deng Yingdao, then looked at Zhang Ran's hand and said, "Brother Ran, your hand is cracked......

Zhang Ran's hands were ugly.

Not only because of the cold weather, but also because he recently experimented with grinding wheels, experimental primers and the like, and it was difficult to think of not cracking.

"It's okay, I'm used to it!"

Zhang Ran smiled, and before he could react, Deng Ying stuffed a pair of woolen gloves into his hand, and said with a red face: "It will be better to wear this......

After speaking, he didn't wait for Zhang Ran to speak, turned around and ran away, like a deer.

"Warm brand gloves, it's just comfortable!"

Mei Zizi put on her gloves, and Zhang Ran suddenly felt warm up and down.

Just returned to the house and didn't sit down, Deng Yi came over to find Zhang Ran, and saw the gloves on Zhang Ran's hand at a glance!

His eyes were turning red rapidly, his teeth were clenching, and his hands were twitching and stretching with extreme force......

Zhang Ran only felt a chill rushing from the tail vertebrae to the top of his head, because Deng Fang's current appearance was definitely very similar to those good people in zombie movies, and suddenly they began to transform into corpses......

Next, it's going crazy and eating people!
