Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.
Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.
The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful, it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.
Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine is stopping coughs.
The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they need only slightly higher levels of capsaicin to cause a cough compared with the placebo.
The researchers said that theobromine worked by keeping down a nerve activity (神经活动), which causes coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.

I was waiting for a phone call from my agent. He had left a message the night before, telling me that my show was to be cancelled. I called him several times, but each time his secretary told me that he was in a meeting and that he would call me later. So I waited and waited, but there was still no call. Three hours passing by, I became more and more impatient. I was certain that my agent didn’t care about my work, and he didn’t care about me. I was overcome with that thought. I started to shout at the phone, “Let me wait, will you? Who do you think you are?”
At that time I didn’t realize my wife was looking on. Without showing her surprise, she rushed in, seized the phone, tore off the wires, and shouted at the phone, “Yeah! Who do you think you are? Bad telephone! Bad telephone!” And she swept it into the wastebasket.
I stood watching her, speechless. What on earth...?
She stepped to the doorway and shouted at the rest of the house, “Now hear this! All objects in this room-- if you do anything to upset my husband , out you go!”
Then she turned to me, kissed me, and said calmly, “Honey, you just have to learn how to take control.” With that, she left the room.
After watching a crazy woman rushing in and out, shouting at everything in sight, I noticed that something in my mood(情绪)had changed. I was laughing. How could I have trouble with that phone? Her antics helped me realize I had been driven crazy by small things. Twenty minutes later my agent did call. I was able to listen to him and talk to him calmly.

My brother and I were alone at home because my parents had gone for a meeting and they had left me in charge. I was doing my homework while my younger brother was watching TV. Suddenly the doorbell rang. My younger brother rushed to the door thinking that our parents had come home, he unlocked the door and opened it.
Outside stood a tall man wearing a black raincoat and black rubber boots. He said he was a salesman and asked politely if out mother or father was at home.
Without thinking, my brother said:” No.” He asked if we would like to buy some comic books which he was selling. I quickly explained that we were not supposed to buy anything without our parent’s permission.
Then, as I was about to close the door, he forced his way into our house. He took out a knife and forced me to tie up my brother’s hands with some rope which he took out form his pocket. I tied up his hands but tied it in a special way so my brother could untie himself. The man then tied my hands up and locked both of us in the kitchen.
Soon, the went upstairs to search the bedroom for valuables. I managed to teach my brother to untie the rope on the his hands. He then untied me. I rushed to the telephone to call the police, but the line was dead. The doors were all locked from the outside and I did not have the keys to unlock them. Luckily, the robber forgot to lock the kitchen window. My brother managed to get out of the house through the window and I told him to go to the police station nearby and call for help.
