Zhang Sijiu could only advise in the end: "Even if there is no problem with the meat in the future, if there is a wound on the hand, try not to touch it." Many parasite eggs are invisible to the naked eye. ”

The skin is the natural barrier.

Once this barrier is crossed, many things can kill humans.

"Wash your hands more often on weekdays and try not to rub your eyes." When he said this, Zhang Sijiu thought of not only parasites, but also viruses.

I've never heard of a virus that can be transmitted directly through skin-to-skin contact.

But the mucous membranes do not have such good protective ability.

Therefore, the respiratory tract, oral cavity, and eyes need to be protected and try not to contact pollution sources.

The woman nodded again and again, and said fearfully: "With this time, I will never dare to forget!" If there is a problem with that meat in the future, let alone dozens of catties, I won't dare to eat hundreds of catties! ”

She even thought, fortunately, it's herself, what if it's her own man or her son and daughter?

Zhang Sijiu told the woman a few more words to let her have a good rest, and then went to find the woman's husband.

When the man heard Zhang Sijiu explain the reason, he couldn't help but scold: "This stupid woman! ”

But after scolding, his face was more sad, and he sighed: "It's also that I don't have the ability, and my family is too poor, so it's like this-"

Zhang Sijiu doesn't make an evaluation, but it can be seen that the relationship between the couple must be good.

She only told the man to quickly call the rest of the family to come and check and take insecticides, and then go to work on other things.

It happened that the next day there was Zhang Sijiu's class.

Zhang Sijiu talked about parasites - what if there are no specimens? It's simple, go to the vegetable market and buy the chickens and ducks that are old but not fat enough, maybe there will be worms.

Not to mention, there was a group of them that directly opened a surprise.

The chicken's intestines were full of bugs.

Lumps, wriggling, like thin noodles—

A big man scared the eunuch out of his voice, and then knocked over the chair, making a huge movement.

Zhang Sijiu was startled by the sudden scream and collision. When she saw the situation on the dissecting table, she smiled and congratulated the other party: "Yes, yes, you are very lucky, the first chicken was such a big surprise." ”

Everyone's already numb scalp was suddenly made even more numb: what kind of surprise is this?

However, the first one scared them enough.

But as more and more people came out with "surprises", they all became numb in the end.

How can I say it, Sadako is terrible, but I can watch it enough times, and I can see how much of my eyebrows are beautiful?

When everyone reached this point, Zhang Sijiu told them about this case.

In the end, Zhang Sijiu concluded: "This woman, in fact, is lucky, this insect is just under the skin. But think about it, what if it was somewhere else? ”

Originally, everyone only thought that this incident was just enough to make people's scalps tingle, but it was not life-threatening.

But when they heard Zhang Sijiu's words at this time, everyone was taken aback as soon as they diverged their thoughts.

Someone said: "If it's in the head, isn't it a headache?" And there's no way to get it out—"

"If it's in the heart......," someone shuddered, "if you can't say it, it will cause sudden death." ”

"Forget about the liver and lungs, so these two places won't die immediately."

"And what if it's in the eye?"

Everyone brushed and imagined the picture of "a worm writhing and crawling out of its eye sockets", and then brushed a shiver, and then angrily spoke: "Can you stop saying such terrible words!" ”

Zhang Sijiu waited for everyone to diverge almost completely, and then he opened his mouth to correct: "If it is in the brain, it is just a brain pain?" Impossible. This causes edema of brain tissue, changes in brain pressure, and then seizures. If a blood vessel is drilled, it is a cerebral hemorrhage. ”

"In the same way, if it is in various parts of the body, even if it does not look so dangerous, it may cause heavy bleeding due to the rupture of blood vessels."

"Even if you stay in one place all the time, if the number reaches a certain level, it's not just as simple as causing people to lose weight, I told you about bloodsucking insects, right? It can cause a lot of illnesses. In the end, people still have to die. ”

"But none of these are the scariest of them, you know what the scariest is? It is that you have become infected, and your feces, blood, and eggs may be carried. But you don't know, you unknowingly, you spread it to your family, and then spread it to ten, ten to hundred—"

There was silence in the classroom.

Zhang Sijiu sighed: "But when you go to the hospital, the doctor can't find out what kind of disease you have, and he can't even prescribe a useful medicine, so you can only live in pain and wait quietly for death to come." ”

The faces of these students all showed solemn expressions.

Zhang Sijiu looked around and expressed his satisfaction, so he also said seriously: "I often think that this is the reason why we, as doctors, must study tirelessly. Because there are so many diseases in the world, many of them cannot be expressed even in the pulse. At this time, the only thing that can help us make a diagnosis is our own experience and knowledge. ”

"That's why I'm here to teach you."

"If I cherish myself and refuse to preach, then in the end, it will be difficult for all doctors in the world to go further - no matter how hard a person learns, summarizes, and comprehends, he can only reach a certain height. But what if we are willing to share our experience and methods with each other? Or, this knowledge can be learned everywhere, isn't it, when you start studying medicine, you have already seen a lot, and when you make a diagnosis, you should consider more possibilities? ”

"Students, I hope that you will not be stingy in teaching what you have learned to others in the future."

Zhang Sijiu put away the textbook: "Okay, let's stop here today, after class, remember to burn all the parasites, and wash your hands with pancreas a few more times after you go back, and then do something else." ”

She is gone, but these students are all thoughtful.

Zhang Sijiu's words can not be described as deafening.

They had to think deeper, and then they were shocked, and then they gave birth to their own determination, and more thinking about the future.

This is exactly what Zhang Sijiu wants.

It doesn't make sense to demand it only by behavior.

Only thoughts.

If there is a change in thinking, then all actions will change.

She was willing to be the light of fire, even if the impact was small, it would have a faint effect.

Zhang Sijiu walked out of the classroom with brisk steps. The people who stayed in this classroom pondered slowly.

Well, what to eat today? Anyway, as long as it's not noodles, it's fine!

Well, forget about chicken and pork. It's also easy to relate.

Well, go vegetarian or still. Cabbage and tofu are safe!

That's all for today. Cut chili peppers last night, spicy to hand, I didn't dare to touch the keyboard in the morning, as soon as I typed, I felt like my fingers were burning, and it was good in the afternoon. Woo woo, cut peppers later, remember to wear gloves!
