There are countless types of alcohol in the world, if not more than 10,000, but at least thousands.

But no matter what kind of wine, the main ingredient in it is alcohol.

In fact, there is no essential difference between medical alcohol and the alcohol that people drink, and the biggest difference is only one point, that is, concentration.

Only when the alcohol concentration is high enough can the purpose of sterilization be achieved when cleaning the wound.

In the previous battle of Yangquan, many wounded members of the detachment suffered serious crimes because of wound infection, and the lucky ones finally picked up a life, while the unlucky ones such as the martyr Ma Jintian died directly because of the wound infection.

This incident had a huge impact on Han Jinshan.

The death of martyr Ma Jintian was mainly due to the fact that there was no specific drug to control inflammation, but in the first time after the injury, the disinfection after wound debridement was not thorough, and there was also a lot of responsibility.

Of course, this is by no means the responsibility of the health team headed by Han Jinshan, and it is really limited by the conditions of the detachment's hospital.

At that time, the disinfection supplies carried by the hospital, not to mention the good things such as hydrogen peroxide, did not even have medical alcohol, and used the liquor bought by Wang Laogui, and the alcohol after distillation and condensation.

The alcohol concentration of ordinary liquor is generally about 30 degrees to 50 degrees, and the concentration of distilled alcohol is about 60 percent, which is much higher than the concentration of the liquor drunk, but it is still far from the concentration of medical alcohol.

It is not okay to have a low concentration of medical alcohol, but it is by no means as high as possible.

Generally speaking, the concentration of medical alcohol is about 75%, and the effect of wound debridement is the best!

"According to the method taught to me by Deng Gong, I have experimented, and the concentration of this alcohol should be either seventy-four or seventy-five!"

Han Jinshan said excitedly: "In the future, at least the problem of the medical alcohol used in the debridement of this wound will be solved, even if the soldiers are injured, at least at the first level, our hospital can better grasp it!" ”

"Great!"

Zhang Ran excitedly patted Han Jinshan's shoulder a few times as a reward!

He really didn't want to see people die!

If the soldiers died on the battlefield, Zhang Ran might be able to reluctantly accept it, but if the soldiers did not die on the battlefield where they fought bravely, but died in the hospital because of their injuries, that feeling would be too worrying.

Although it is inevitable that in the state of war, the soldiers will die of serious injuries and die in the hospital, but it is Zhang Ran's most sincere wish to sacrifice one less if he can sacrifice one less, and to save one more if he can do his best.

Although alcohol can't solve too many problems, at least it gives those wounded a little more hope to live, how can Zhang Ran not be excited?

He was so happy.

But obviously, Han Jinshan is happier than Zhang Ran!

Because he is the only medic in the detachment!

He is directly related to the life and death of the wounded!

Although even if the soldiers died in the hospital, as long as he did his best, it was not his responsibility at all, but for Han Jinshan, he couldn't help but think that it was all his own problem!

And with alcohol, the soldiers can be more sure of living, for him, that kind of satisfaction, even Zhang Ran, can not fully understand!

After asking some questions about alcohol purification and whether the output can be used, Zhang Ran said: "Dean Han, having you in charge of our detachment hospital is really a blessing for our detachment and a blessing for all the wounded...... On behalf of our wounded and our fellow villagers, thank you! ”

I mean this from the bottom of my heart.

Although Han Jinshan's medical skills are not the best, his medical ethics are absolutely high, his attitude is absolutely responsible, and he is the most suitable doctor for the detachment hospital!

"Captain, I should thank you!"

Han Jinshan looked at Zhang Ran emotionally and said: "My dream since I was a child is to be a good doctor, but unfortunately my family is too poor to have this opportunity at all......

Thinking of his own kung fu with this three-legged cat, after he came to the detachment, he was appointed by Zhang Ran as the military doctor of the detachment and the director of the detachment hospital, not to mention the important tasks, but also created conditions for himself to improve his medical skills in all aspects - not only invited famous doctors everywhere to teach his experience in medical skills, but also asked Miss Deng to tutor herself in literacy, help herself get medical books for herself to study, and get all kinds of things for herself to do experiments......

Now, his medical skills have made great progress, not only the general illness is easy to catch, but even the general surgery is not difficult for him, and he can often hear the villagers calling themselves miracle doctors!

Thinking of this, Han Jinshan's eyes turned red, and he felt that Zhang Ran was simply his reborn parent, and he couldn't wait to kneel down and thank him!

"Dean Han, what are you doing - work hard for the detachment, treat a few more wounded and sick, that is the best reward for me!"

Looking at Han Jinshan's grateful appearance to himself, Zhang Ran was very relieved, quite a kind of old master teaching students, and finally a student was the top student in high school, and then came back to thank him for his great gratitude, which was extraordinary.

I feel that I am the Bole who is good at discovering Maxima, a talent that others can't recognize, and I just have a sharp eye and a look at it.

As for when Han Jinshan came, he didn't look down on this guy at all, and appointing Han Jinshan as the military doctor of the detachment was completely a choice he was forced to make because he couldn't find a better candidate, Zhang Ran had long forgotten about it!

Where does Han Jinshan know this?

This guy is patting his chest fiercely, saying that he must do his best and die, otherwise, he will not be able to repay Zhang Ran's kindness and cultivation!

"Yes, yes!"

Hearing Han Jinshan's repeated assurances, Zhang Ran was comforted, and praised and encouraged again, and then said in a low voice: "What happened to the penicillin matter?" ”

This incident was the task that Zhang Ran secretly arranged for Han Jinshan after Ma Jintian was infected and died last time.

Penicillin, an antibacterial drug, is so important for a team in the war years!

Although Zhang Ran's understanding of penicillin is limited to the fact that the plaque can be collected from the cyan plaque on the shell of the orange peel melon, and then cultivated with a nutrient solution, and then isolated and extracted this fur, this does not prevent him from letting Han Jinshan tackle key problems in this direction.

As for the equipment that does not have all kinds of related experiments, such as the most basic microscope to observe the activities of fungi, there are no problems at all, for Zhang Ran, there is no problem at all.

Anyway, it's not him Zhang Ran who does the experiment himself!

These difficulties, he is very single, let Han Jinshan find a way to overcome them first, and slowly find a way on his own side.

This is not to say that Zhang Ran is irresponsible, but this is not something that can be done at all!

Even those big Yankee companies and big laboratories have been more than ten years since the discovery of the effect of penicillin in the past two years, and they have spent so many dollars to make penicillin mass-produced.

His idea is simple, that is, try to do it!

If you get it out, that's a great thing, and if you can't get it out, it's not a loss, after all, you can't lose anything!

But even so, in terms of confidentiality, Zhang Ran really did it according to the fact that penicillin may be successfully developed at any time!

In the entire detachment, except for himself and Han Jinshan, no third person knew!

No way, once penicillin is really made, the value is too great!

If the detachment really relied on the Bodhisattva to bless the Buddha and merciful it, and accidentally got penicillin out, once the news reached the ears of the little devil, it would really be a good thing to turn into a funeral!

Zhang Ran suspected that the little devil estimated that he would be able to immediately mobilize more than a dozen divisions to deal with his small Jindong detachment, and he didn't bother to play with the chairman on the frontal battlefield!

If it spreads further, it is estimated that the European and American powers will be able to come over and fight World War II on the territory around this Jindong detachment!

Such a serious consequence is something that Zhang Ran never wants to see.

"I can't say ...... either"

Hearing Zhang Ran's question, Han Jinshan said with a distressed face: "Anyway, the plaque and everything are collected according to the method you said by Captain Zhang, and the nutrient solution is also prepared according to the method you said by the captain......

As for the rest, Han Jinshan can only catch blind.

I can't help it, I don't understand it at all!

Although he has been making rapid progress in medical skills these days, this cultivation of penicillin has almost nothing to do with medical skills!

It's all about microbes!

In the current era, people's understanding of microorganisms has just begun, and only a very small number of people have some half-understood knowledge.

Not to mention any decent experimental equipment, not even a microscope for observation, everything can only be done by eye......

What can you see with just a pair of eyes?

Zhang Ran knew this, looked at Han Jinshan's sad appearance and sighed: "Dean Han, it's really hard for you......"

Zhang Ran's understanding made Han Jinshan extremely moved, and he said: "Otherwise, captain, you come with me to take a look-you know a lot, maybe you can see what the way is!" ”

“……”

Zhang Ran was speechless, because he didn't understand this thing!

Knowing something from the Internet, and the distance between understanding it, even if it is not as far away as a few galaxies, it is estimated that it is not too close!

Not to mention that he only sees with his eyes now, he can't see anything at all, even with a microscope and other things, Zhang Ran is sure that he still can't see anything - he doesn't even know how to distinguish penicillin bacteria from other fungi.

But at this time, Zhang Ran can't be cowardly!

If he, the person who proposed the plan, was cowardly, then Han Jinshan, who was blindly touching an elephant according to his guidance, couldn't he be even more cowardly?

Therefore, in the face of Han Jinshan's earnest invitation, Zhang Ran could only bite his heart with his teeth, nodded stubbornly, and said in his heart that he would go and have a look, and he would not die!

Besides, even if I didn't see anything, I was embarrassed, and it is estimated that with Han Jinshan's consciousness, I would not laugh at myself.

Moreover, have you been laughed at less these days?

Thinking about it like this, Zhang Ran was relieved, straightened his chest and belly, and let Han Jinshan lead the way, just like the big leader of the inspection work, and went to the laboratory.
