Leeches, commonly known as leeches, can be found almost everywhere in wild rivers. It's an animal that can make most women feel creepy, and even men feel extremely disgusted when they get stuck to it.

But it's a good thing for doctors and patients with cardiovascular or cerebrovascular diseases or cancer. Huaxia discovered the miraculous use of leeches very early, and leech therapy was once popular abroad.

In recent years, some pharmaceutical companies have made oral leech powder by concocting leeches at different temperatures, which has been widely used.

With the development of biotechnology, hirudin, the most valuable substance in leeches, has been successfully extracted and mass-produced on a small scale, but it is still in short supply. Although scientists have also begun to produce hirudin peptide protein for artificial synthesis of hirudin peptide protein as a template, the efficacy is still not comparable to that of naturally extracted hirudin.

There are more than 100 species of leeches in the wild in China, but only three or four are determined to be medicinal. There are quite a lot of leeches in the rivers of Lingnan Province, and in terms of species, they almost cover more than 100 kinds of leeches found in Huaxia.

He didn't know the scientific name of this kind of leech, but the master once told him that he was called an ant leech. As the name suggests, leeches are the size of ants, but they can parasitize certain fish and other animals, and their habits vary greatly from ants to ants.

Leeches are sensitive to the smell of animal wounds or lesions, and can quickly track the animal host according to the smell in the water, and pass through the blood vessels of the animal to reach the wound or lesion. For wounds, hirudin secreted by leeches can quickly and effectively repair wounds, eliminate clotting and blood clots.

Leeches do not have high oxygen requirements, and leeches have a greater advantage over other large leeches in terms of oxygen consumption due to their small size. They can maintain their vitality in the body through the oxygen carried by the host's blood, and in the absence of sufficient oxygen, they can turn into a sac and go into a dormant state, floating in the host's blood all the time.

Pharmacologically, ant leeches are not much different from other leeches, but almost no one knows about their use. An ant leech can't do anything, and the leech emperor must be found, because only the leech emperor can reproduce offspring like the queen ant. Leeches are originally hermaphroditic and allogeneic fertilization, which means that a leech is both female and male, but if you want to reproduce offspring, you must pass another leech to achieve it.

The leech emperor is similar to the queen ant in this regard, as long as it is fertilized once, it can produce for life, and under the right conditions, it can produce a large number of leeches, and the development of leeches under such conditions is also quite amazing.

It just so happened that when the cycad was a child, he saw the master use this thing to heal a patient, and put an ant-sized leech emperor near the wound, and it didn't take long for this thing to burrow into the human body, which scared him a lot. Later, I learned that this is also a kind of leech treatment.

However, it is not easy to find the Ant Leech Emperor, not only because of their small size, but also because there are few such creatures in nature, and the number of reproduction times is usually quite small. Especially in the current river pollution, the water contains all kinds of toxic substances, not to mention ant leeches, even the large leeches that were common in the past are difficult to find.

The cycads left the hospital and ran straight to the nearest farmer's market, where they needed some tools to catch leeches. In fact, there are special tools for catching leeches, but this thing is just some niche supplies, and cycads don't know where to get them for a while.

Fortunately, it is not difficult to make some simple tools, and the most common way is to find a container to hold pig blood and put it in the water, if there are leeches nearby, they will naturally follow the smell of pig blood into the container. As for the container, it is much simpler, from bottles to tiles, from dried loofah tendons to bamboo tubes, as long as it can be filled with pig's blood or glued to pig's blood, it can become a container.

It's just that it takes luck to catch the Leech Emperor. Cycad bought a hundred dried loofah tendons as containers at once, hoping to win by quantity. Then I bought a plate of pig's blood, and then took a taxi and ran non-stop to the wetland park in the Lotus River Basin.

There are not many rivers and lakes in Baocheng, but only the Lotus River is relatively well protected at present. The river originates from the spring of Lianhua Mountain, and the area along the river from south to north is in the remote countryside or mountainous area of Baocheng, and there are even several small-scale nature reserves, including the wetland park. At present, the Lianhua River Basin is the only natural area in Baocheng that can maintain an intact ecosystem, and the chance of finding leeches here is naturally greater than in other places.

After getting off the taxi near the wetland park, Su Tie realized that it was too far, and it cost two hundred and forty yuan to come out of the city, so he asked Su Guanting to help arrange a car. Fortunately, the 20,000 yuan I received from the beauty salon is still on my body, so I won't be shy in my pocket.

In the eyes of many people, the interior of the wetland park is actually quite a dirty place. Except for many people playing and taking pictures on the periphery, the central area is almost inaccessible.

In particular, the black mud from the decay of various leaves emits a foul smell, which makes people feel very uncomfortable, let alone people with a sensitive sense of smell like cycads.

But it is also the smell of nature, every leaf, every dead animal, has found its final home here, and finally the dust returns to the dust, and then becomes the nutrients of other creatures and obtains a special new life.

According to the leech's ability to avoid light and like adsorption, the cycad found several dark corners where aquatic plants were abundant, and then stuffed almost congealed pig blood into dried loofah tendons and put them into the murky water.

The water inside the wetland park is so slow that it is not visible to the naked eye, and the cycads do not have to worry about pig blood being washed away.

A hundred dried loofah tendons stuffed with pig blood were put into the water, and the cycad took a long breath, and when he looked at his mobile phone, he found that it was already more than four o'clock in the afternoon, and he could only wait for now. It is estimated that a lot of leeches will be harvested tomorrow morning, because the cycads have already seen with their sense of smell and even with the naked eye that there are many leeches hidden in the grass nearby. But the need for the Ant Leech Emperor is too rare, I hope to see these things tomorrow.

At this time, Su Guanting actually called, and Su Tie chuckled in his heart, and suddenly had a bad premonition.

"Wang Nan gave me the treatment of Jianyì abandonment. Uncle Shen's old wound in the skull not only failed to stop the bleeding, but also appeared two new bleeding points, and he told us to prepare for the worst, it may be in the next few days......," Su Guanting said with a choked voice on the phone.

I have already estimated this. Although Wang Nan's "construction yì give up treatment" does not conform to the professional norms of doctors, it is no wonder that he made this construction, but I don't know on what occasion he made such a construction. In terms of traditional treatment options, Shen Weizhong has reached this point where it can no longer be maintained.

But for a while, Su Tie didn't know how to comfort her, as long as he could find the Leech Emperor, Shen Weizhong could be considered hopeful. But whether he can find the Leech Emperor, he doesn't dare to pack a ticket. He had to say, "Don't worry, Dr. Wang, they may have done their best, and they can last as long as they can." ”

"I feel really uncomfortable to let Uncle Shen live like this for the sake of our conscience. I don't know if Uncle Shen is conscious, if he is, I believe that he is definitely worse than dead now. At this time, I even thought that he could leave sooner so that he would not suffer such pain. My dad was already on the plane to Baocheng, and it is estimated that the family is also preparing for the last step. Su Guanting finally couldn't help it and cried on the phone.

This made Cycad wonder if what he had done was correct. Even if they found the Ant Leech Emperor, it would give Su Guanting and them a hope, but what if it didn't work?

It was a sad feeling to go from hope to despair. Unlike Su Guanting, their family has a deep relationship with Shen Weizhong, let alone Shen Weizhong lying on the hospital bed. I can't understand their feelings, but I just think about them from the perspective of helping people as an outsider.

Su Tie's heart suddenly panicked, he really hated his nose, why did he let himself know so many messy things.

"Miss Su," Su Tie said into the phone, "I feel sad too." Since Dr. Wang and they have all given up, to say something offensive, it is better to be a dead horse and a live horse doctor, you let me try. Give me a little time, just two days, and there will be news as soon as tomorrow morning. I'm sure Dr. Wang will be able to keep Mr. Shen alive for two days. Once I have found the medicine for the treatment, please help me convince the hospital and even your home. ”

Su Guanting paused for a moment and said, "I can do it." In addition, the medicines you want me to find, except for the bezoar, have been prepared. The bezoar has actually been found, but it will take a little time to get to Baocheng. ”

Ending the call with Su Guanting, Su Tie looked at the surrounding Yiqiē, and his heart was confused. Looking back on what I have encountered, it is actually nothing more than my own troubles.

Why did she follow that woman more than four years ago to tell her that she needed to do everything she could to check her arteries and blood vessels, and finally provoked a rape case for herself, ruining her good future.

Why did you provoke Wang Xiaohua a few days ago? Fortunately, he escaped without danger, but he lost his job and provoked Li Qingwei.

Why be a hero in the bank? Let yourself eat a bullet for no reason.

Why save Serenity in the orchard lair of the thugs? He had to be admitted to the hospital and came into contact with Shen Weizhong's condition.

Even if he came into contact with Shen Weizhong, it was because he wanted to help save him because he had a lot of things, so he let himself stay in this broken place to catch leeches, and he was still nervous in his heart.

Cycad laughed self-deprecatingly, as if everything he did was not good fruit for him. But if you think about it carefully, it doesn't seem to be true, at least there is one more sister, although I haven't seen her yet, but it feels as refreshing as eating ice cream in the hot summer.

Thinking of his sister, Su Tie's heart began to get excited again, and after this matter is over, he will ask Li Ping if there is any news over there.

"What are you doing here? Didn't you know that tourists are not allowed to come here? ”
