Chapter 381

Lao Liu said, "there is a well near the entrance of our Hutong. It's not in other people's home, and no one is in charge of it at ordinary times, so we've been drawing water from it these two days."

Shi Xiaorui said, "is there any water in this well? Show me. "

Old Liu hesitated to see her one eye, don't know what Shi Xiaorui wants to do. However, he was very cooperative. He walked slowly to a water tank with a bamboo cover on the side of the house, lifted the bamboo cover, scooped out some water from it and handed it to Shi Xiaorui.

Shi Xiaorui took over and asked first.

How to put it? There is a light, I don't know how to describe the taste, it must be different from the usual drinking water.

Then she carefully touched the water with her index finger, dipped a little water, and put it into her mouth to taste.

If you can, Shi Xiaorui certainly does not want to choose such a dangerous judgment method, but who knows that she will meet this situation today? There are no testing tools, so we can only use the most primitive method to test the poison.

The entrance of the water was a strange smell that could not be covered completely. Shi Xiaorui vomited it immediately after she was sure. Then she quickly took out the light salt water in her medicine box and rinsed it back and forth several times.

The heavy metal in this water should be vanadium.

This heavy metal sounds strange. It's not as famous as lead poisoning, mercury poisoning and thallium poisoning, but it can also damage people's heart and lung, cause serious damage, and cause high cholesterol.

However, the amount of accumulation in Lao Liu's body is not very large. It is estimated that the taste of the water is too big, so the water intake is relatively small. This is also unfortunate.

The more troublesome point of heavy metal poisoning is that this poison is different from other poisons, and basically will not be biodegradable, that is, it can not be eliminated or diluted by conventional means, but will continue to accumulate in the human body until it becomes more and more serious and directly kills.

However, Lao Liu discovered this early. He only ate it for two days at most, and I'm afraid it's only the minimum dosage required by the human body, so the treatment is still far from enough.

Shi Xiaorui thought about the treatment with a straight face. The remaining people in the yard didn't know what Shi Xiaorui wanted to do. When they saw her taste the water in the water tank, then spit it out and gargle, they knew that there must be a big problem with the water.

Niu Er was in a hurry at that time. He contacted Shi Xiaorui a little more and understood her character. Instead of talking about her words, he asked her, "doctor Shi, what's wrong with the water?"

Shi Xiaorui said: "the well water they called contains heavy metals. After eating this water for several days, they have had mild heavy metal poisoning."

I said so, but several people still don't know what it means.

Heavy metals in water?

It's pure water. There's no iron filings in it.

Shi Xiaorui doesn't know how to explain it to them. It's a simple knowledge of physics, but these people don't have the common sense of physics. After thinking about it, Shi Xiaorui can only simply say: "some metal bubbles in the water for a long time will disperse and mix in the water, so although this water can't be seen, it also contains this kind of metal. These invisible metals enter the human body, some of which are toxic, causing heavy metal poisoning. "

A few people still look like they don't know how to listen.

Shi Xiaorui had no choice but to say, "don't worry about heavy metals. The water is poisonous. Lao Liu drank the water for two days, so he was poisoned."

That's a lot easier to understand.

Niu Er quickly asked: "doctor Shi, is this easy to cure?"

Shi Xiaorui said: "to be able to cure is to work harder. Fortunately, it was discovered earlier. Don't go there to get water in the future. If you want me to say that, you'd better seal up the well completely, so that no one else can drink it by mistake. "

To tell you the truth, Lao Liu's family is so poor that they have to drink the water from that well. Other people, even other animals, may not drink the water with such a bad smell.

Lao Liu was also afraid. Who could have thought that the water he thought was just bad water would contain toxins?

But in this way, you have to buy water every day.

Lao Liu's eyes unconsciously looked at the bamboo baskets and straw sandals piled everywhere in the yard, and sighed silently.

Shi Xiaorui wants to treat this heavy metal vanadium poisoning. She also needs several rare medicinal materials. Her own medical library is not complete, so it is estimated that she will have to go to several large medical libraries to ask.

Put this aside first, Shi Xiaorui looked at Lao Liu's injured ankle and asked him, "when did you hurt your foot?"

Lao Liu looked at his lame leg. He had been used to it for so many years. He almost thought that he was born with such a disabled leg: "when he went to war, he fell to the ground and was trampled on by cavalry, and then he was like this."

Shi Xiaorui was also surprised. I'm afraid Lao Liu didn't mean trampled by a cavalry. He meant trampled by a cavalry on a horse. Only with the weight of a horse and a man and the weight of a suit of armor can a man's foot be trampled on a bone.

Shi Xiaorui said softly, "can you show me the injury?"

Lao Liu didn't feel like he had been stabbed in the pain. As soon as he reached out, he lifted his trouser legs up, revealing a strange twisted ankle.

Shi Xiaorui squatted down and came close to see his wound.

The wound was not smooth, and the skin was mixed with different shades of red. It was obvious that he had suffered a very serious injury.

Shi Xiaorui asked, "can I pinch it?"

Lao Liu said, "pinch it. In fact, in recent years, I can hardly feel the pain. "

But since it can move slowly, it means that the nerve is not completely necrotic, and the tendon of the foot is not broken at least, which is slightly better than the most serious situation predicted by Shi Xiaorui.

Shi Xiaorui just saw not enough, she also rolled up her sleeve, carefully touched the injured ankle inch by inch.

Niu Er can't stop looking at Lu Shao.

Lu Shao stands beside him, calmly looking at Shi Xiaorui's up and down movements, turning a blind eye to Niu Er's eyes.

Because he could see that Shi Xiaorui was simply treating patients. If she really took advantage of others, why should she touch her injured leg. What's more, it's not that he has too much self-confidence. In any aspect, objectively, he can leave Lao Liu behind, so what can he worry about?

In fact, Lu Shao misunderstood Niu Er.

Niu Erzheng is nervous. What does Shi Xiaorui want to do? Is he sure to cure Lao Liu's leg?!

Lao Liu's leg has been injured for so many years. He used to be a good soldier, but now he's become like this. Sometimes Niu Er doesn't dare to come to see him, for fear that he will not feel good when he sees the pity in his eyes.
