There are some stories about the inventors of the telegraph. Samuel F. B. Morse, an American painter, was deeply inspired by a young doctor named Charles Jackson who showed an electromagnet on a ship in 1832. Morse then decided to turn his studio into an electromagnetic laboratory to study electromagnetism. He faced many difficulties and even spent all his money on experiments, but he still continued with the help of friends and by painting to earn a living. He had a unique research idea. He thought that the sudden cut - off of current to produce electric sparks could be signals, and the absence of electric sparks and the length of time without them could also be signals. These three types of signals could be combined to represent numbers or letters. Finally, in 1835, he developed the first sample of the telegraph in the United States. And in 1838, he invented the unique Morse code composed of "dots" and "dashes". Charles Wheatstone, a 19th - century British physicist, also made contributions to the invention of the telegraph. He and Cook (W.F.Cooke) invented the five - needle telegraph in 1837. Before them, there were also other inventors' attempts. For example, in 1833, the German scientists Gauss and Weber developed an electromagnetic telegraph and used a deflecting magnetic needle to transmit information. They also had their own "secret code" for transmission. However, their invention was not widely used due to some practical problems. And in 1835, the Russian scientist Schilling also invented a practical telegraph machine. Read more exciting novels for free

Does gastric reflex have anything to do with the respiratory tract? Is it serious? How to treat it?

There was a close relationship between gastric reflex and respiratory tract. Stomach-esophagus Reflux Disease can cause a variety of respiratory symptoms and diseases. In terms of chronic cough, gastroesophagus was considered to be one of the most common causes of chronic cough. About one-third of chronic cough was caused by gastroesophagus. Reflux of gastric contents or microaspiration into the trachea may be the main mechanism, and many patients do not have typical symptoms of gastric esophagus. As for bronchial asthma, the asthma caused by gastroesophagus reflex is called gastroesophagus reflex associated asthma. Adult-onset asthma, asthma without intrinsic factors, asthma with poor effect of bronchiodilators and hormones, nighttime asthma, or asthma related to lying down may have gastroesophagus reflex associated asthma. About one-third of gastroesophagus reflex associated asthma does not have typical reflex symptoms. Stomach esophagus is also related to chronic sore throat, which is one of the important reasons why chronic sore throat is difficult to cure. Its main symptoms are clear throat, cough, sore throat, hoarseness, foreign body sensation in the throat, etc. In addition, it was also related to aspiration and hospital acquired pneumonias, lung interstitial inflammation, apneic syndrome, and so on. The main treatment principle for respiratory complications of gastric-esophagus reflex was to suppress gastric acid secretion. Standard doses of various proton-pump-inhibition agents could quickly relieve the symptoms of gastric-esophagus reflex. For patients with severe cough and expectoration symptoms, cough medicine such as Feilike mixture can be used for symptom treatment. Do not lie down after meals, avoid stimulating food, quit smoking, and stop drinking. For the treatment of the primary cause of cough and expectoration, commonly used drugs are proton-pump inhibition drugs such as omeprazol, rabepraol, etc., which can reduce the production of gastric acid and reduce the phenomenon of acid repulsion; gastric prokinetic drugs such as domperidone, mosapride, etc., can accelerate the secretion of the digestive tract and reduce the time that gastric acid stays in the digestive tract; If there is a respiratory infection, antibiotics such as amoxicilin can be used. For patients with a history of respiratory symptoms related to the symptoms of gastroesophagus reflex disease, 20 milligrams of Omeprazol was administered twice a day as a rule. All the above medicines should be used under the guidance of a doctor. Self-medication should be avoided. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
