He didn't want to be like Kang Ting, who could survive on such a dangerous battlefield in the Golden Immortal Temple, more than 600 people died and more than 400 guys who didn't have red circles under their eyes, returned to the base area, and the moment he saw Lu Yan, he remembered that he could come back alive this time, and when he didn't know if he could be so lucky next time, he was a few steps away from Lu Yan and cried......

Therefore, Zhang Ran now hopes for a person.

He came to this era alone, and if he died in battle, he would be alone!

Maybe Long Xin and Deng Ying will cry for themselves, but they should soon forget, after all, life has to go on, and they still have to live......

But if I have more involvement with them, then this life will be bound together......

If they die, they will never be able to let go!

Zhang Ran didn't want to see that.

Han Jinshan was very haggard.

Not only was his hair greasy and his eyes sunken, but even his face, under the extremely dim light of the generator's power supply, was pale and could not see the slightest blood, like a dead man......

Zhang Ran patted Han Jinshan's shoulder, he could understand the other party's mood.

After all, Han Jinshan is a doctor!

He desperately tried his best to save the wounded, but those wounded were constantly dying, that feeling, like a person who wants to hold on to the most precious things and not let anyone steal them, but can only watch those precious things leak through his fingers bit by bit......

That kind of powerlessness and despair, Zhang Ran, who had just come out of the ward, felt the same way!

"Ninety percent of the wounded who died were due to uncontrollable wound infections......

Han Jinshan sniffed and stared at a spinning centrifuge made by Xu Kunjun himself, and in the test tube on the centrifuge, there was liquid slowly separating with rotation......

Obviously, those test tubes should be penicillin bacteria that have been recently cultured.

"If the effect of penicillin is really as strong as you said, captain, as long as there is penicillin, Wang Wenping and more than forty of them, I can save at least half of them!" When Han Jinshan said this, he didn't raise his head.

Zhang Ran patted Han Jinshan's shoulder again, not knowing what to say.

Because he knows that things will never be as simple as Han Jinshan ideals.

Although now, the laboratory for secret penicillin experiments is much more complete than when it was first decided to start a laboratory.

Not only microscopes, beakers, measuring tools, test tubes, and even simple centrifuges for separating penicillin have been made......

In addition to the increase in experimental equipment, after the accumulation of these days, Han Jinshan's understanding of penicillin has also improved too much, and it is not at all like Zhang Ran's original search for intestines and stomach scraping to recall some knowledge about penicillin that he once swept on the Internet, and he doesn't even know what penicillin bacteria look like......

But even if you make so much progress, what's the use?

Not to mention whether the penicillin isolated from this rudimentary experimental equipment is pure enough to meet medical standards, what if it is achieved?

So many wounded people need penicillin, and with these rudimentary equipment, how much penicillin can be produced?

How much can penicillin be prepared in a day and night with such rudimentary experimental equipment? Can there be a million units?

And for each casualty to control inflammation, the amount of penicillin needed to be used every time is at least 500,000 or 600,000 units to have a significant effect......

One wounded person needs so much at one time, let alone so many wounded!

The production yield per unit of penicillin is not up to standard, which is the fundamental reason why penicillin was discovered more than ten years ago, but it has not been able to be used in clinical practice for a long time!

Even the well-capitalized laboratories of the European and American powers will not be able to solve the problem for a while, and it is not easy to solve it easily by relying on themselves and Han Jinshan......

Of course, it is impossible for Zhang Ran to tell Han Jinshan!

In this way, it will deal a devastating blow to Han Jinshan's enthusiasm......

And from the very beginning, Zhang Ran had a clear understanding of the difficulty of preparing penicillin for the detachment, so he would not say it!

What's more, although I know that with the equipment and research level of the detachment, it is extremely difficult to prepare penicillin that has not been prepared by the European and American powers so far, but compared with those laboratories, it is not completely without advantages!

Because Zhang Ran has followed the knowledge about penicillin in his memory, coupled with Han Jinshan's uninterrupted adjustment for most of the past half a year, he has formulated a relatively suitable culture medium for cultivating penicillin bacteria!

Although it is certainly not up to the level of mass production of penicillin, it is obviously far above the international advanced level compared with the research on penicillin at this stage in history!

This is also the fundamental reason why Zhang Ran knew that it would be difficult to make penicillin happen, but he still made up his mind to do it!

He didn't ask the laboratory to make penicillin an industry, but as long as he could prepare a certain amount of penicillin and save a few wounded who were already hopeless, he was already very satisfied!

Not to mention, with Han Jinshan's continuous research, the understanding of penicillin is also increasing, and Zhang Ran believes that in the case of quantitative changes causing qualitative changes, a virtuous circle will eventually be achieved......

After all, it's only been thirty-nine years!

And historically, penicillin was invented by the Yankees and used in clinical practice, which is already three years later!

And even if it is invented, more penicillin will be used in the Yankees' own team, and even if a small amount of penicillin flows into the Chinese theater, the value will be in gold, and ordinary soldiers will not be able to use it at all!

Therefore, no matter how much penicillin the detachment can produce in the end, as long as it is produced, it will be a huge blessing for all the Chinese soldiers who shed their blood for this war!

"This batch of penicillin, at most two days, can be purified!"

While Zhang Ran was thinking about this, Han Jinshan was already staring at Zhang Ran nervously and said, "Although the quantity is pitiful, the concentration of penicillin bacteria per unit is not up to standard, and I dare not guarantee that it is pure enough...... But I still want to use it directly as a human test! ”

"Are you crazy?"

Zhang Ran's scalp immediately tingled when he heard this-this matter, it's not a joke!

Any drug is manufactured, it needs to be rigorously tested to determine that there are no side effects, determine the dosage, and finally act in the clinic!

According to what Han Jinshan said, as soon as it is purified, it will directly act on the clinic, which is simply disregarding human life!

Zhang Ran found that this guy is really getting more and more like a lamb doctor!

But Han Jinshan obviously didn't think that he was careless about human life, and stared at Zhang Ran with burning eyes and asked: "Several people in the ward area of the seriously injured, such as Wang Wenping and Wang Company Commander, can't wait for us to continue the test - Wang Wenping's belly, because of the suppuration, is so rotten that there is no place to put a needle in it...... Can you imagine the belly rotting like tofu, with the sutures passing through it and slipping off the rotten flesh in a few moments? ”

"Don't talk about it!"

Zhang Ran's scalp tingled and said, "You can do whatever you want......

Anyway, it's all dead horses as live horse doctors, even if it's really a matter of carelessness, it doesn't make much difference......

Of course, Zhang Ran still did his best to explain to Han Jinshan what he knew about the use of penicillin......

Although penicillin is an antibacterial miracle drug, it acts on wound inflammation and so on, and the effect is extraordinary.

However, because of the medicinal properties, not every patient with inflammation is suitable for use, because if the body is unwell, the use of penicillin will not only fail to control inflammation, but also cure the disease and save people, but will cause allergies and make the patient die faster......

"Before using penicillin, be sure to do a skin test!"

Zhang Ran said, seeing that Han Jinshan was puzzled and explained carefully: "First take a small dose of penicillin for skin experiments, observe the reaction, and make sure that if there is no redness, swelling, rash and other violent reactions at the medication site, then increase the injection dose - you must come step by step, don't think about eating a fat man!" ”

These are not things that ordinary people can know at all.

After all, for this era, penicillin is a completely new thing - Zhang Ran said this, obviously suspected of an unpredictable prophet.

But Han Jinshan didn't react more because of this, but after glancing at Zhang Ran, he nodded and said that if penicillin was isolated on time, he would definitely do what Zhang Ran had explained, and he was willing to ask Zhang Ran to come to the scene at that time!

"Don't call me anymore......"

Zhang Ran hurriedly waved his hand, he really didn't want to see Wang Wenping grabbing his hand and begging for death in pain.

It was enough to experience that scene once—and if it could, he wouldn't even want to experience it once.

Not to mention that now Han Jinshan is simply desperate and directly experiments on living people......

Zhang Ran was sure that if there were really anyone among Wang Wenping's wounded who survived because of penicillin at this stage, it would not be because penicillin was directly successful or anything else......

It was purely that the wounded man was protected by the gods and Buddhas, and the ancestral grave at home was smoking!

After explaining what he could, Zhang Ran left the hospital and went to the back mountain.

Houshan is now busy, and all workshops are already running at full capacity!

In this battle, the sacrifice of the detachment was extremely heavy, but all kinds of captures, it was also extremely rich!

The devils are extremely strong, not only in terms of combat skills and tactics and the quality of individual soldiers, but also in the fact that when they are dying, as long as they have a breath left, they will try their best to destroy their weapons, and they would rather break them than cheap the enemy......

In the battle of the detachment, after all kinds of battles, there were countless devils annihilated, so there were many guns destroyed by the devils before they died.

Now, the guns are piled up in several caves, and the blacksmith's workshop has been turned into a legendary repair shop, all busy repairing all kinds of damaged guns.
