This composition is about 800 words in Grade Three. The topic is "Tuberculosis and Me". Everyone is welcome to contribute enthusiastically. During the winter vacation, my cousin coughed for a month and the medicine was not good, so my aunt took her cousin to the hospital for examination. A few days later, the test results came out and found that my cousin had "primary tuberculosis", and everyone was very anxious. What is primary pulmonary tuberculosis? Next, let me tell you more about it.

Primary pulmonary tuberculosis is the first time that Mycobacterium tuberculosis invades the human body and reaches the lungs through the respiratory tract to form an infection. Especially in childhood, because the infection rate of the first tuberculosis is 90% in the lungs, primary tuberculosis is usually called primary tuberculosis. Pulmonary lesions are characterized by primary syndrome consisting of primary lesions, lymphangitis and hilar lymphadenopathy.

How's it going? Isn't it terrible? But my cousin's family didn't stay away from and care about her physical and mental condition. Look!

Aunt can hurt her cousin to wipe her hands for a while, feed her cousin for a while, and tell her jokes for a while ... it's very comfortable to see me. In fact, what is the purpose of aunt doing this? No, it's to make my cousin feel free from psychological pressure, cooperate with the doctor's treatment with peace of mind and get better as soon as possible.

Through the careful observation of doctors these days, it was found that the early focus of tuberculosis was at the apex of lung. Why? There are three reasons, and the mechanism is not completely clear. It is generally believed that there is little activity in the lung tissue at the apex of the lung, and once tuberculosis enters, it is easy to stay and cause lesions. There is less blood flow at the apex of lung and relatively more oxygen in alveoli, which is beneficial to the reproduction of tuberculosis. The reasons for the low apical activity and blood flow are: (1) When breathing quietly, the expansion range of the lung is small at 3: 1; (2) Due to gravity, the blood flow in the upper part of the organ is less than that in the lower part; (3) The pulmonary artery branch at the apex of the lung is narrow and long, so the amount of blood reaching the apex of the lung is less, and it is difficult to absorb oxygen, so the alveoli contain more oxygen. In addition, the lymphatic circulation in the lung apex is slow, and it is difficult for mycobacterium tuberculosis to enter the lymph nodes and be swallowed, which may also be a reason why the lung apex is prone to tuberculosis.

Through the doctor's description, we further understand that tuberculin experiment has two advantages: (1) can help diagnose tuberculosis; (2) You can introduce the target of BCG vaccination. We also know that there are five principles to be mastered in tuberculosis chemotherapy: (1) early treatment; (2) rational drug use; (3) combined medication; (4) Adequate dosage; (5) the course of treatment should be enough.

Through my description, students should remember!

Interested students can try to do some publicity. Our slogan is: "Only love can make you healthy." After a series of treatments, my cousin finally got out of her misery!

Willow spread its soft branches and danced wildly.

Happy swallows are singing and skimming over the treetops. Ah!

What a beautiful spring scene!

Oh!

What's the good news? Spring has come, and my cousin has been cured. This is what people often say, "double happiness at the door"!
