Zhou Heng's cheeks trembled, and he held back the heart that kicked the person out, and grabbed Xiao Liuzi's arm.

"The concentration of the agent is to extract five-grid penicillin, then push it out, and then extract five-grid saline. This is the concentration of the test liquid. Then inject the test liquid into the skin around the cunguanqinqi to form a papule the size of a rice grain that cannot be covered and scratched, and it will be observed after a quarter of an hour."

After saying that, Zhou Heng let out a long sigh. He couldn't calculate how to express it if he diluted 800,000 units into 50 units. Everyone was confused about this. Zhou Heng made a rough calculation. His ratio was only a little higher, but it was simple and easy to calculate. Now he can only be so unified.

After changing to a sterile needle, Zhou Heng raised it and gestured.

"Whoever is interested in you can try each other. This is not difficult. It is just that when injecting, you must form papules in the skin, otherwise there will be no point in observing it."

Ma Lingshan and Liu Xiu'er raised their hands. They took the syringe and quickly started to try and tried each other. Zhou Heng looked at Ma Lingshan's arm and said to Liu Xiu'er.

"Xiu'er did a good job, but don't wipe it when you see bleeding. It's better to be superficial next time."

Liu Xiu'er pursed her lips and smiled secretly, feeling very happy. Zhou Heng looked at Liu Xiu'er's arm and quickly raised the candlestick.

"Everyone comes to see, Xiu'er has allergic pimples. You guys come to see, this is very typical."

With this sentence, several heads came to their eyes, and somebody's hair was pulled and burned, and the smell of burnt suddenly filled the room.

I saw that the test-sensitive papules on the inner side of Liu Xiu'er's arm were a little red, and a red thread extended from the pinhole to the opposite side, which was very obvious.

Liu Xiu'er's face was so happy that she was suddenly nervous. She was actually allergic to new drugs. What should I do? Isn't that saying

"Second brother, then I can't use new drugs in the future?"

Zhou Heng smiled at Liu Xiu'er and said, "Don't be depressed, this is just the first batch of test products. If it can be refined twice, the efficacy and allergicity of the medicine will be lower. After Achang slowly explores it, the new medicine will continue to improve."

Liu Xiu'er then breathed a sigh of relief and looked at everyone and reminded him:

"It's already time, so hurry up and eat and study."

Ma Lingshan and the others nodded quickly, "Yes, don't delay your business, go for a meal, but you have to ask patients to test the new medicine, and the price can be higher."

Everyone went downstairs and came to the cafeteria. Wangcai had already arranged all the dishes and prepared all kinds of food. When he saw someone coming, he called everyone in for dinner.

While eating, Achang asked Zhou Heng some questions. Not to mention that they were all key points in pharmaceuticals, but Zhou Heng could only help him. At this moment, a slapman ran over in a hurry.

Seeing a few people having a meal, I stopped and hesitated on my face.

Zhou Heng looked up at him. The boy seemed to be following Qu Ziping to arrange patients in front of him, and was responsible for cleaning and keeping the door closed sooner or later.

"What's wrong, just say something."

The boy hurriedly held his fists and said, "Boss, a few people came in front of him and said that they came from Jiyang County and the car broke down on the way, so he arrived at this moment. One of the old men said that he had come to Huichuntang a few days ago and asked Dr. Ma that he was asking for his son's leg injury and fracture and whether the severe swelling could be cured."

Ma Lingshan quickly threw down the steamed bun in his hand, wiped his mouth and stood up.

"Is that the highly infected patient here? But it's been so many days since this, and people are still alive."

As he said that, he moved towards the door. Zhou Heng put down his food, stood up, turned around and reminded him.

"You eat slowly first, Ma Lingshan and I will go and see. If surgery is needed, it will be too late for you to finish it."

After hearing what Zhou Heng said, everyone also accelerated their meals. Zhou Heng took Ma Lingshan to the clinic with the servant.

An old man kept wiping his sleeves, his whole face covered in sweat. When he walked closer, Zhou Heng discovered that the four of them were carrying a fat man with the door panel.

The man's legs were like steamed buns on his face, his facial features were twisted, his face was sallow and his eyes were closed, especially his legs, one of his legs had his pants cut off his pants, and a wound kept flowing out of yellow and white liquid, and the wounds were covered with yellow pus.

Zhou Heng was stunned. It was the first time he had seen a patient with such severe infection when he traveled here.

Even when the plague was treated, the toes of the dying old man did not reach this level. If the infection of this level is not controlled in time, he will only be amputated.

The old man looked at Zhou Heng and Ma Lingshan with a look of hope, and distinguished it with the candlelight, and knelt down to Ma Lingshan with a plop.

"Doctor, please save my son. The house is built to marry him. Who would have thought that the beam of the house would slip and smash him? We went to more than a dozen clinics in Jiyang County and treated them. After some treatment, it was even worse. We wanted to go to Jinan Prefecture, but I heard that there was a Huichuntang in Qingping County who was the best at treating such injuries. So I came here."

Ma Lingshan looked at Zhou Heng, and at this time he felt unsure. Such serious bone injuries and infections would be gone if he accidentally had no life. If someone died in the clinic, there would be no one to come to the door. Obviously, the clinics before were also thinking this way.

"I remember you, five days ago, you asked me if the wound of a bone injury can be treated if it swells. Didn't I tell you that you should seek medical treatment immediately, why did it take so long to come?"

The old man raised his sleeves and his face was filled with tears, and he turned around to look at the person on the wooden board.

"I think too, but after I got home, my brother found a doctor and was treating my son. He said that he had bone resection and reduced the swelling. He had to take a few days to see if the swelling could be reduced. The money had been spent. We thought we should try it. After a few days, the person had already doubled his swelling, so we didn't dare to delay and came to Qingping County directly. Who knew that he had entered the city and the car was broken. There was no way we carried the people into the city."

Ma Lingshan turned his head to look at Zhou Heng. Such a patient was really too serious. He was unsure and asked in a low voice:

"Master, will we treat this patient?"

Zhou Heng looked up at Ma Lingshan. Zhou Heng was worried about him. It was understandable that Zhou Quan was a good thing as a doctor. He also considered Huichuntang's reputation. If this person could not be cured, he would directly smash his signature.

Zhou Heng's eyes fell on the old man, and he helped the old man sit down, and then said slowly:

"Old man, people can cure it, but we have to make some things clear. Your son has been delayed for too long. Our doctor has also reminded you before that we must first control the infection of his wound. Only by controlling the infection can we see the location of the fracture and whether the treatment is reasonable. If the bone assembly is misaligned, it is necessary to re-engage the bone, which will increase the patient's pain. Of course, if the infection is not controlled well, the leg cannot be saved. At that time, we will focus on saving our lives. The leg needs to be cut off. Have you figured it out?"

The old man shook his hand, looked at Zhou Heng helplessly, sat on the ground, and cried even more sadly.

"It's all my father's greed. If I didn't feel sorry for those few taels of silver, it wouldn't delay your illness. What should I do? What should I do?"

Ma Lingshan was a little anxious. It was already a great thing for Master to agree to the treatment. He was so moved that he hurried forward and squatted beside the old man.

"I didn't say I couldn't treat it, I just explained the possible situation to you clearly. Don't really change the condition and have to need amputation. You don't agree with each other. You were delayed in time, but now you still have to delay?"

When the old man stopped tears when he heard this, he climbed to the wooden board and patted the man on the cheek.

"Son, you wake up, how do we choose?"

The man on the wooden board woke up leisurely, opened his eyes effortlessly, looked at Zhou Heng, and Gaba said with difficulty:

"I treat it, and I treat it even after cutting my legs. The doctor saves me and writes it. This is my own choice."

The old man got up, wiped his tears, and approached the man.
