The title of this essay is: "I and tuberculosis". During the winter vacation, my cousin coughed for a month in a row, and the medicine was not good, so my aunt and uncle took my cousin to the hospital for a checkup. After a few days, the test results came out, and it was found that my cousin had "primary tuberculosis", so everyone was very anxious. What is "primary tuberculosis"? I'll tell you more about it.
Primary tuberculosis is the result of the first invasion of tubercle bacilli into the human body, which reaches the lungs through the respiratory tract and becomes infected. It is especially common in childhood, as 90% of first-time tuberculosis infections are in the lungs, so primary tuberculosis is usually referred to as primary pulmonary tuberculosis. The lungs are characterized by a primary syndrome consisting of a primary lesion, lymphangitis and enlarged hilar lymph nodes.
How's that for scary? But my cousin's family didn't stay away and didn't care and didn't ask about her physical and mental condition. Voila!
Auntie can pain cousin a moment to cousin wipes hands, a moment to cousin feed, a moment to cousin tell jokes ...... look at me all comfortable, in fact, auntie did this, is for what purpose? No, it is in order to let cousin no psychological pressure, peace of mind with the doctor's treatment, as soon as possible well.
Through the doctor's careful observation in the past few days, he found that the early stage of tuberculosis foci on the tip of the lung, why? There are 3 reasons, the mechanism is not completely clear, it is generally believed that the lung tissue in the tip of the lung is less active, once the tuberculosis bacteria enter, it is easy to stay and cause lesions. The blood flow in the lung apices is low, and the alveoli contain relatively more oxygen, which is favorable for the reproduction of tuberculosis bacteria. The reasons for the small activity and low blood flow in the lung apices are: (1) when breathing calmly, the expansion range of 3:1 on the lungs is small; (2) the blood flow of the organs, due to the relationship of gravity, are less than the lower part of the upper part of the lungs; (3) the pulmonary artery of the lung apices has a narrow and long branching, so that the amount of blood arriving at the apices of the lungs is less, and oxygen is not easy to be absorbed, and thus the alveolar oxygen content is more. In addition, the tip of the lungs of the lymphatic circulation is slow, so that the tuberculosis bacteria are not easy to light Lymphatic channels into the lymph nodes are swallowed, may also be the tip of the lungs susceptible to tuberculosis of a reason.
Through the doctor's description, we further learned that the tuberculin test has two benefits: (1) it can help diagnose tuberculosis; (2) it can introduce the target of BCG vaccination. We also learned that there are five principles that should be mastered in the chemotherapy of tuberculosis: (1) early treatment; (2) rational use of drugs; (3) combination of drugs; (4) adequate dosage; (5) sufficient course of treatment.
Through my description, students should remember oh!
The students who have the heart can try to do a little publicity, our slogan is: "There is love to have health." After a series of treatment in the middle, cousin also finally out of the sea of suffering !
The yellow willow tree spreads its soft branches and dances a crazy dance.
The happy swallows sang and swept through the treetops. Ah!
What a springtime scene!
Oh!
What is the good news?
What is the good news? It's that spring has come, and it's that my cousin has been cured, and that's what people often call "double happiness"!
