Gu Li would return to the hall every night, and the first thing she did after returning was to see the patient after the operation.

His wound was recovering well, and Gu Li watched him get better day by day, feeling more and more relieved.

Three days later, in the evening, Gu Li and Mei Zhiyan left the observation institute and went to the laboratory again.

Without a microscope, she couldn't identify the species that caused the disease, but if it was a gram, then penicillin must have killed it.

Before the lid of the petri dish was lifted, both of them were in a state of uneasiness.

"Come on." Gu Li took a deep breath and said to Mei.

"Hmm." Mei Zhiyan replied softly.

There was only one petri dish in front of him, and because the penicillin prepared before had been proven to be effective, there was no need to set up a control experiment.

Mei Zhiyan also took a deep breath, and then reached out and lifted the lid of the petri dish.

The eyes of the two looked inside in unison.

"This—" Mei couldn't tell if the experiment had succeeded or failed.

Gu Li didn't immediately draw a conclusion, but picked up the petri dish and observed it carefully.

The strains inside appear grayish-white and are certainly not staphylococcus. Gu Li carefully observed it for a while with the bright light, and then sent the petri dish to Mei Zhiyan: "Look at it, is the color of the edge lighter." ”

Mei Zhiyan took it from her hand and looked at it carefully.

"It seems to be."

"So our experiment was successful?" Mei Zhiyan raised her eyes to look at her.

Gu Li pursed her lips, thought for a moment, and replied: "The results of the test are not clear, and it is difficult to say now." ”

There is indeed a bit of change in the petri dish, but it is too vague to declare the experiment successful in this way, it would be too unrigorous.

"Can this medicine be used on epidemic patients?" Mei Zhiyan asked again.

"Why don't you try?" Gu Li proposed.

Mei Zhiyan seemed a little worried and did not reply.

Gu Li said again: "This medicine has been tried and can prove safe." If it is applied to a patient with an epidemic, it will not cause any harm if it is not symptomatic. ”

If it's symptomatic, that's a great thing.

Hearing her say this, Mei Zhiyan nodded.

Anyway, there is no special medicine now, so try this, it is not impossible.

When Gu Li left, she brought penicillin with her, planning to try it on the patient's body tomorrow.

She first informed Mei Zhangyuan of this matter, and Mei Zhangyuan did not object.

Gu Li chose a patient with more critical symptoms, even though she knew that this medicine would not have any bad effects, but before taking the medicine, she still notified the patient's family and informed them of the possible risks.

The patient's family trusted her and did not question it.

After taking the medicine, Gu Li has been staying by the patient's side, observing and recording the changes in his condition from time to time.

For the first two hours, the patient's body did not change much, and he remained the same as before, fever, coma, and sometimes vomiting. But by the third hour, the patient's body temperature began to drop slowly, and the person still did not wake up, but the symptoms of vomiting had been relieved a lot.

Gu Li saw hope, and suddenly felt ecstatic in her heart.

If the disease is relieved, it means that penicillin has a therapeutic effect on this epidemic.

She still didn't relax for a moment, and continued to observe.

Four hours later, Gu Li gave the patient another dose of penicillin.

After nightfall, she did not leave, still staying by the patient's side.

The next morning, when Mei Zhangyuan came to inquire, Gu Li excitedly said to him: "It has an effect!" ”

Obviously she didn't sleep all night, and she was nervous all the time, but she didn't feel tired at all, but she was still excited and energetic.

Mei Zhangyuan heard her say that it had an effect, and he was immediately excited.

"Can it be used on all patients?" His voice, trembling with excitement, asked.

Gu Li nodded with great certainty: "Yes." ”

But after a pause, she suddenly added, "However, some people are allergic to penicillin, so you have to do a test before using it." ”

Although not many people are allergic to penicillin, if an allergic reaction occurs, it can have serious consequences. Therefore, to be on the safe side, it is better to try before taking the drug.

"How?" Mei Zhangyuan asked again.

"Let's try it on your skin first, if you have allergies, it will have a reaction."

Because the previous two patients belonged to the kind of patients who couldn't do without penicillin, she didn't do the test before taking the drug.

"Well, you'll be solely responsible for that." Mei Zhangyuan entrusted the use of the new medicine to Gu Li.

Gu Li nodded solemnly: "I will definitely live up to the trust." ”

"Okay, okay", Mei Zhangyuan said several times in a row, and said, "I will tell everyone the good news, so that their hearts can settle down." ”

"Hmm." Gu Li responded.

When she and Mei Zhiyan were preparing penicillin, they just tested whether penicillin had an inhibitory effect on the pathogenic bacteria of the epidemic, but they didn't expect it to be really effective, which was really unexpected.

The first patient to be treated with penicillin gradually stabilized. It was also from this day that penicillin began to be widely used in epidemic patients.

Outside the observation center, everyone rushed to tell each other, passing the good news to each other. The epidemic, which took hundreds of lives and put everyone in Changning City at risk, finally had a way to restrain it.

Gu Li also breathed a sigh of relief, with penicillin, she no longer had to watch so many people lose their lives every day.

Thinking of the helpless and sad scene, Gu Lijue's heart was bitter and sore, and two lines of tears couldn't help rolling down.

"I'll see, you go drink the medicine." Mei Zhiyan walked over at some point and said next to her.

Gu Li hurriedly wiped her tears and responded with a smile: "Okay." ”

She walked out of the observation hall and went to the medicine distribution to fill a bowl of medicine. This is a medicine to enhance her physique, she will drink it every day, and as a healer, she must have a strong body. Only when you are healthy can you help more patients.

Gu Li picked up the medicine bowl and was about to drink the medicine, when she suddenly heard someone calling her behind her.

"Doctor Gu, I feel a little dizzy and want to vomit again, come and take a look at me."

Gu Li did not refuse, put down the medicine bowl, and walked over.

This patient had also used penicillin, and Gu Li was afraid that something would happen to him, so he went over immediately.

After some inspection, it was found that there was nothing wrong with him.

"It's okay, just rest assured. You may be too nervous to feel uncomfortable. Gu Li comforted him.
