[Infrastructure] Rose kissed Barcelona

When the people of Barcelona were preparing to celebrate the victory over the plague, Joey ordered several baskets of citrus and melons shipped from Valencia on the premise of confirming the safety of the supply.

This east coast fruit has a pleasing appearance. The yellow and fresh citrus has a plump skin, like a bunch of little suns, exuding a burst of fresh and slightly sour fragrance.The melon is small in size, with some light green lightning-like cracks on the milky white skin, and its fragrance is stronger and sweeter than that of citrus.

For fear of plague, people have not eaten fresh raw food for some time.All food is either boiled or stewed, including all vegetables and fruits.

So, with the warm wind blowing in the early autumn, the aroma of fresh fruits permeated the whole building. Everyone in the Fernandez House smelled the intoxicating aroma like an alcoholic who hadn’t drunk for a long time, and couldn’t control it at all. own hands.

When Joey found out about this, he quickly stopped everyone with green eyes: "Wait a minute, don't eat it up! These are materials for experiments, leave me a basket."

"How to do this experiment?" Mary, who had recovered, regained her vitality, and when she heard that there was another experiment after class suspension, her eyes lit up.

"First, there's the mold on the citrus and melons."

Everyone: "...My God!"

Is she serious?

It is shameful to waste food.

Of course Joey meant it.

She is working on the preparation of penicillin.

The idea came after a cholera outbreak.

When interacting with the hospital's experts, Joey quickly found himself ignoring an important fact—in this era, no one has ever seen antibiotics.

Although the treatment of cholera is not too difficult, to improve the treatment efficiency, on the one hand, a large amount of water loss needs to be replenished, and on the other hand, antibiotics are also needed to reduce inflammation.

Doctors listed her traditional remedies for cholera and other infections—bleeding, decoctions of white willow bark, or mercury or silver solutions.

The toxicity of mercury has been proved in the joint research done by Joey and the University of Barcelona, ​​so now the hospitals in Barcelona have banned the use of mercury for treatment.

I don't know what the ingredients are in the white willow bark, and there may be some practical basis for making medicinal soup.

But bloodletting and silver solution... Joey hurriedly spread the word to doctors that bloodletting would definitely only speed up death when patients lost a lot of penis.

As for silver?Silver is a heavy metal, and the silver solution will make the fresh and transparent raw pork turn white as if cooked, so please imagine the situation of cooking the meat in your stomach after drinking it.

"That really depends on God." A doctor sighed.

"Don't be too pessimistic, the human body's own immune system is very strong," Joey explained, "Of course, we also need to try other ideas."

She had done experiments on the preparation of penicillin in biology class.

In all fairness, the preparation process is not very complicated.However, the experiment at that time was only used for learning, and it was absolutely impossible to use it in practice.After entering large-scale industrial production, penicillin only costs a few cents, and no one can tell how many toxins produced by bacteria will be in homemade penicillin.

Now that this technology is really going to be used to save lives, Joey feels very complicated.

Medical research is about life, and worrying often leads to big problems.In view of the fact that the research needs a certain period, even if it is really successful, it may not be used to deal with the plague this time. Joy emphasized to the Department of Health that the focus of dealing with the plague is to stop the spread, and don't have too much hope for new research.

The failure rate of this experiment is quite high, and there may not be a few of the hundreds of culture media that can successfully cultivate the required Penicillium, not to mention the failure rate caused by limited sterile conditions, and screen out as much as possible. High-yielding strain.

Even experiments need to be done in batches.

Joey sorted out the experimental ideas and sent them to the biology schools and hospitals of several universities in Barcelona. He also began to try to restore the previous experimental procedures.

Vincent was also very interested in the experiment, but in view of his reputation of being careless and forgetful, Joey ruthlessly rejected his request, and only took Mary to start the experiment.

After the citrus and melons have successfully molded, scrape the blue-gray mold into the potato juice in a glass bottle and let it stand for a week.

During this week, the whole city is still in a state of emergency, but the atmosphere is changing little by little.

Cases are down.Many more recovered.

A week later, Joy remembered that it was time to filter the medium.

After filtering the very turbid culture solution at this time, add olive oil and stir to dissolve organic impurities, and then remove the grease after standing for stratification, leaving a solution that has removed a layer of impurities.

"That life-saving fungus is in it?" Mary asked curiously, staring at the clear solution.

"It's better to be here." Joey smiled, "Otherwise, I will torture it a few more times, scraping it off the melon again and again, so that it won't eat the melon well."

Mary couldn't help laughing too, the innocence of a child finally appeared in her pale blue eyes.

In fact, Joy was a little nervous—the more she got to this kind of time, the more she talked to relieve her nervousness.

Hope it works.

She rested for a moment, then added carbon powder to the solution until all the liquid in the large test tube was gone, sucked into the black powder pile.

"Ready?" Joey asked Mary.

"Yeah." Mary nodded.

In front of her is a standard set of distilled water preparation equipment. The round bottom flask has been heated for a while, and the clear and transparent distilled water falls down the long glass tube into the test tube that has been boiled and sterilized in advance.

It must be sterile cooling water, which is very important for the success of the experiment.

Holding his breath, Joey carefully took the distilled water handed over by Mary, washed the solidified toner a few times, then added vinegar for a few times, and finally washed it with seaweed juice for a few more times—this is really a job that tested patience .

Finally came to the last step, facing a lot of petri dishes - all petri dishes were divided into two groups AB, group A kept sterile, and group B was injected with Staphylococcus aureus colonies cultured in the previous week for use Test the antibacterial effect of the culture medium.

The bacteria Staphylococcus is easy to find, just pick it up from everyone.

After transplanting strains in dozens of Petri dishes.Still have to wait another week or so.

During this week, the mood in the whole city was almost visible to the naked eye.

If someone can go to the streets freely, they will find that the citizens no longer close the doors and windows as they encountered the plague several times before this century, but open the doors to ventilate, and sprinkle lime and disinfectant on the empty corridors and room floors. With the products of these sciences, they can escape their bad luck.

The city hall arranged for special personnel to clean and disinfect the streets, and all the cisterns were opened for investigation.Architects and engineers worked day and night to design new water and sewer systems, and the whole city was due for a major overhaul.

In the crematorium, all belongings of the cholera victims were burned.The flying gray-black dust flew into the sky, and in the eyes of the people wrapped in face scarves, it looked like the hasty footprints of death.

When the week finally passed, the good news finally spread throughout Barcelona with the newspapers.

It wasn't until night fell that day that Joey returned home from the outside, feeling so tired that he was about to fall apart.

No way, statistics work is always so exhausting.

But she knew the importance of the work she had just done—humility is a virtue, but in this day and age, for a certain group of people, it means a lot to be seen.

This will allow them to take the first step.

With the first step, there will be the second step, the third step, and unrestricted running.

Wait until tomorrow morning, people will see their contribution.

Joey yawned in satisfaction and came to the laboratory again.

There were several rows of densely packed petri dishes, and she looked over one by one, feeling like a poor gardener, anxiously checking how many seedlings she had planted and how many had survived.

When she finally saw the zone of inhibition in several Group B petri dishes, she let out a long breath.

Ah, how lovely are these few petri dishes with slate-gray fuzzy colonies.

It is conceivable that it will become the darling of all mankind.

After Joey washed hastily in relief, he fell asleep.

Finally passed.She needs to get a good night's sleep.

In the early morning of the next day, there were exclamations one after another in various hospitals in the city.

"Oh my god!"

Beren looked at the bunch of bluebells that had been forced into her hand in surprise, her fair cheeks blushed suddenly, "Is this for me?"

"Thank you for your care." The handsome young man said with a smile.

She knew him—the two were nurse and patient.

"Also, I see that you seem to be very interested in law. In fact, I am studying law at university. If you don't think I'm presumptuous, maybe I can help you."

Belen's voice was so nervous that it lowered down, meowing like a cat: "No, no, it's not presumptuous at all... You are so kind, sir."

"Don't call me sir," the young man shook his head resignedly, "I'm not a few years older than you."

"Call me Adrian, my dear lady."

Not only Belem, many girls received flowers this morning.

Many of them also meticulously tied their long hair into headscarves, shuttling among hospitals of all sizes.However, there were no more patients—the plague was over.

The harbor city, which had been silent for several weeks, resumed operation with the morning sun.

The whistling siren sounded from the port, the rumbling train whizzed past on the track, and the sound of trams and horseshoes once again interweaved into the most pleasing sonata on the street.

For the people of this city, that means life.

It was also with the morning newspaper of this day that people suddenly discovered that the girls who had taken care of them or passed them by in the hospital were not professional nurses.

But when you think about it, it's almost obvious—previously, most nurses were men.

As their names appeared in the newspapers, people were even more surprised to find that half of them came from poor families and half from rich or even prominent families.

The families of many of them fled Barcelona in the first place.

But they didn't go.

Perhaps because they had stronger confidence in Miss Fernandez than others, they stayed and made indelible contributions in this disaster.

No matter what the reason is, when the plague is in the past, their courage and love also changed history together with this battle that is enough to be recorded in the annals of history.

For the first time, they became the glory of the family.

This is also the first time that people have realized very clearly that when girls trapped at home come out of the house, they are not only people who fought for their rights with fierce means before, but also brave and protective forces for society.

Beren put his face close to the bunch of fresh and delicate bluebells in his hand, and took a deep breath.

Very light, very light fresh fragrance, like the first ray of morning light in early summer.

She suddenly felt that her eyes were a little moist.

"Thank you, Joey," she said softly.

Joey woke up suddenly from his sleep, panting with some palpitations.

Perhaps it was because she was too tired, her dreams were full of strange lights, and her sleep was restless.

It was sunny morning light outside the window, and the street was noisy and lively.

...But, isn't this a little too lively?

Joey was dazed on the bed for a while, then yawned again, then walked to the window and opened the curtains a little.

All drowsiness suddenly disappeared.

Looking down from upstairs, you can see that the entrance of Fernandez House has become a sea of ​​flowers.

It's early autumn, and the sea of ​​flowers is full of cornflowers, alyssums and sunflowers, as well as many roses and roses.The morning sun falls on these fresh flowers, and the rich fragrance of flowers is still refreshing even up to the fourth floor.

A sea of ​​colorful flowers surrounds the main entrance of Casa Fernandez.People who don't know think that some kind of celebration is being held here.

Joey rubbed his eyes in disbelief, suspecting that he was dreaming.

"……Oh my god."

The author has something to say: Joey: Okay, so shy (*///▽///*)

Joey: Wait, the flowers in front of the door are piled up...why do you always feel that something is not right?

Thanks to Lei, the little angel of water beauty, and thanks to the lemon essence bubble water and the nutrient solution of the sea breeze~
