Phlegm is transformed by the body fluid of the lungs. Its chemical properties are quite complex and contain a variety of substances.
Phlegm contains water, which is one of its main components. The proportion of water in phlegm is quite high, which makes the phlegm have a certain degree of moisture and fluidity, allowing it to move in the respiratory tract.
Furthermore, phlegm contains proteins. These proteins come from a variety of sources, some are secreted by the mucosa of the respiratory tract to protect the respiratory tract; some are released by immune cells or produced by damaged tissues during inflammatory reactions. Proteins give phlegm a certain viscosity, allowing it to adhere to foreign bodies.
Inorganic salts are also components of phlegm, such as sodium, potassium, calcium, and magnesium plasma. They play a role in maintaining the osmotic pressure of phlegm and electrolyte balance in the body. Although the content is relatively small, it is indispensable.
In addition, phlegm often contains white blood cells. When the respiratory tract is attacked by pathogens, white blood cells will go to the battlefield to defend against foreign enemies. Some white blood cells will be excreted with phlegm after battle, so white blood cells are common in phlegm.
At the same time, there may be pathogens in phlegm, such as bacteria, viruses, and fungi. These pathogens are the main culprits that cause respiratory diseases. They can be transmitted through phlegm, causing others to become infected.
There are also foreign bodies such as dust and pollen mixed in phlegm. During daily breathing, tiny particles from the outside world will enter the respiratory tract, and phlegm traps these foreign bodies by virtue of its viscosity to ensure the cleanliness of the respiratory tract.
In short, phlegm has multiple chemical properties, and its components are closely related to the health of the respiratory tract. Through the observation and analysis of phlegm, it can provide important clues for the diagnosis of diseases.

If you want to make dinitrophenol, there are various methods. It is described in "Tiangong Kaiwu", and it is described in Chinese today.
First, you can use phenol and nitrosulphur to make. First take an appropriate amount of phenol and put it in a corrosion-resistant device. The phenol, which is warm in nature and has a certain chemical activity, is the basis for making this medicine. Then add the agent of nitrosulphur by slow method, and the agent of nitrosulphur, which is strongly oxidized, will chemically change when it encounters phenol. Be careful when adding, because the two touch each other, the reaction will be intense, and it is easy to cause danger. Stir while adding, so that the two are even, in order to promote the complete reaction. During the reaction, you can see the smoke rising and the temperature rising sharply, which are all violent reactions. Wait for the reaction to slow down, let stand in a suitable temperature place, so that the product gradually formed.
Second, other methods can also be used. Phenol and nitrate are combined first, and the nitrate needs to be pre-treated to make its activity appropriate. Mix the two in a special kettle, the wall of the kettle needs to be thick and the heat conduction is good. To slow the fire and gradually heat up, the temperature should not rise sharply at the beginning to prevent the volatilization of phenol and the uncontrolled reaction. With the rise of temperature, the two gradually combine. Watch its change, adjust the temperature in time, or add additives to promote the reaction. Auxiliaries can change the rate of the reaction and the quality of the product. When the material in the kettle shows a specific color and state, it can be known that the reaction will be completed. The temperature is lowered by the cold method to obtain the crude product of dinitrophenol.
Crude products need to be refined and dissolved in water or other solvents to remove impurities. When dissolved, the temperature and the amount of solvent are controlled to make dinitrophenol completely soluble and the impurities insoluble. Then the slag is removed by filtration method, and then the solvent is gradually removed by steaming method to obtain pure dinitrophenol. In this way, a usable product can be obtained.
The method of preparing dinitrophenol, although each has its own differences, needs to be handled with caution, understand its chemical principles, and control the degree of its reaction, in order to obtain its good products and ensure safety.

There is a question today, the efficacy of the two medicines, the occurrence of the three diseases, in what field is it applied?
The two medicines of the husband, one can cure wind disease, and the other can solve tuberculosis. Wind disease, mostly occurs between the limbs and meridians, people walk, sit and lie down, all depend on the smooth flow of meridians and qi and blood. If it is invaded by evil wind, the meridians are blocked, or the limbs are painful, or the flexion and extension are unfavorable. This medicine can dredge the wind and clear the collaterals, so that the qi and blood can resume, so it is widely used in the fields of orthopedics and traumatology, acupuncture and massage. When healers treat, they often use this medicine to assist patients to make the meridians smooth and relieve pain.
As for antituberculosis drugs, tuberculosis patients are mostly due to weakness of righteousness and erosion of tuberculosis insects, which are often found in the lungs, kidneys and other viscera. Pulmonary tuberculosis coughs and hemoptysis, hot flashes and night sweats; kidney tuberculosis is sore at the waist and knees, and the body is thin. This drug can replenish righteousness and anti-tuberculosis insects, and is very useful in the treatment of lung and kidney diseases in the internal medicine of traditional Chinese medicine. Doctors treat patients according to their symptoms, distinguish and treat them according to their syndromes, and reasonably combine this drug to help patients restore viscera function, enhance physical fitness, and control tuberculosis insects.
Three diseases, one is cold disease, the other is heat disease, and the third is wet disease. Cold diseases are mostly caused by exogenous cold evil or yang deficiency and internal cold, and are common in winter or people with plain yang deficiency. Cold coagulation of blood vessels, cold pain in the limbs, abdominal pain and diarrhea and other symptoms occur. This is common in the fields of internal medicine and gynecology of traditional Chinese medicine, such as women's uterine cold infertility, men's cold hernia abdominal pain, can be caused by cold diseases. When treating, when the method of warming the yang and dissipating the cold, the drugs used may be related to the medicine for treating cold diseases.
Hot diseases, or exogenous warm evil, or internal viscera heat accumulation. Common hot topic, irritability, thirst and other diseases, in pediatrics, infectious diseases, etc. Children's pure yang body, prone to heat disease; exogenous warm evil, can also cause hot topic does not retreat. At this time, when the medicine to clear heat and laxative fire to treat it, so that the heat evil clear, all symptoms self-solution.
wet disease, often due to humid climate, wading in water and rain or spleen deficiency caused by dampness. Wet evil is heavy turbid and viscous, left in the skin meridians, the body is heavy and sleepy, joint pain; trapped in the spleen and stomach, bloating, loose stools, loss of appetite. In the field of spleen and stomach diseases, dermatology and other fields, wet disease is quite common. Medicine for treating wet disease, or strengthening the spleen and dampness, or aromatic moisture, to remove dampness evil, restore viscera function.
To sum up, the two drugs and three diseases have their applications in many fields such as osteopathy, internal medicine, gynecology, pediatrics, infectious diseases, spleen and stomach diseases, dermatology, etc. Doctors should distinguish diseases and use them rationally to achieve the purpose of treating diseases and saving people.

At this time, the karma of those who are not in the city has a rather promising future. Looking at the present moment, people's feelings are often trapped in various things, or they are tired because of the rush of livelihood, or they are heartbroken because of the cold world. The karma of those who are not in the city can just be used for catharsis.
And the world is gradually increasing in the pursuit of emotions. In the past, perseverance was the most important thing, but now they know the need to express their feelings. The karma of those who are not in the city can lead people to tears and relieve their worries, like the melting of snow in spring, and the accumulation of depression in the human heart. Therefore, in the way of adjusting emotions, this karma is at the right time.
Furthermore, in the market, although the style of entertainment is complex, it can touch the heart and reach the soul. The karma of the snotty person moves people with emotion, making people feel in tears, and relieved in sadness, which is unique. Or play the clutch between the world, or talk about the vicissitudes of the world, when you hear it, you will feel emotional, tears will flow, and the burden in your heart will go away.
As for business, the cost of this business is not huge, but the audience is quite wide. Everyone has feelings, and the emotions will be snotty. No matter whether you are rich or poor, you need it. If you are good at management, you will use exquisite methods to attract people to flow, make people convinced, and you will make profits.
Although there are small disadvantages in the industry, such as people or people who are ashamed to be runny, if over time, the concept will gradually change, and people will know the benefits of catharsis, this industry will be greatly prosperous in the city. Therefore, the industry of the runny person has a bright future. If the sun rises, its road is bright, and if it is operated with wisdom, it will be able to occupy a place in the city and become a grand event.

The journey of the spittoon, pay attention to the general things. The first and most important material is to be selected, and the material is not necessary. It is suitable for solid, durable, and anti-corrosion materials, such as ceramics and gold. Ceramic spittoons are dense to the ground, smooth on the surface, not easy to hide dirt, and resistant to acid and rot; gold spittoons have high spittoons and are not easy to break. However, all materials must be of high quality in order to be durable.
Furthermore, the shape of the spittoon should not be ignored. The shape of the spittoon is easy to use, usually in the form of a barrel or a tube, with narrow upper and lower edges, so that it is not only conducive to sputum spitting, but also can keep it firmly placed, not easy to overturn. And its depth needs to be appropriate, which is easy to cause sputum to spit out, and deep and inconvenient to clean. In addition, the surface of the spittoon should be smooth to prevent the user from accidentally breaking it.
The workmanship is also difficult. If it is a ceramic spittoon, the manufacturing process is not easy to control, so as to ensure the integrity of the ceramics, cracks, trachoma and other defects. The processing of the gold spittoon, the welding is firm and flat, and the grinding process is necessary to make the surface glossy and burr.
The consideration of cleaning is also indispensable. The spittoon is used to hold sputum, which is easy to breed bacteria, so its parts are easy to clean, and it should have certain antibacterial properties. Antibacterial drugs can be added to the material, or antibacterial treatments can be performed on the surface to reduce the growth of bacteria.
The most, the color of the spittoon is also studied. It is suitable for daily necessities, but it is also suitable to have both beauty and generosity.
