¡¾ÌâÄ¿¡¿Researchers are finding new ways to save snakebite victims.Experts discussed the latest findings during a recent conference.

Scientists in Australia have shown that a chemical called nitric oxide could increase the chances of surviving a poisonous snakebite.The scientists injected rats with a deadly amount of snake venom.Then they rubbed an ointment(Èí¸à)containing nitric oxide on the skin around the injection site.The study found that the rats lived about one-third longer than if nitric oxide had not been used.But the treatment had to be started very quickly.

Dirk van Helden led the research.He says the nitric oxide ointment also showed promise in humans.The study appeared earlier this year in the journal Nature Medicine.Scientists say the findings could help save many lives.A recent study found that poisonous snakes cause as many as ninety-four thousand deaths worldwide each year.But Ulrich Kuch of the Biodiversity and Climate Research Center in Frankfurt,Germany,says that number appears to be low.

Mr Kuch says many deaths could be prohibited if snakebite victims are treated correctly,but they often go to traditional healers or do not seek any help at all.He said,¡°Sometimes it¡¯s because there is no treatment available¡ªno antivenom(¿¹É߶¾ÑªÇå),which is the specific(ÌØÊâµÄ)drug to treat snakebites¡ªor health care staff do not know how to treat snakebites,and sometimes its because transportation to get to a health facility is not available or too expensive.

Here is no single antivenom that can be used to treat all snakebites.The antivenom must be specific to the kind of snake that bit the person.In some countries the treatment is costly,while in others there is no such treatment.

¡¾ÌâÄ¿¡¿An old friend from California called from the airport to tell me that he had arrived. I was not able to leave the office, but I had made plans for his arrival. After explaining where my new house was, I told him that I had left the key under the doormat (Ãŵæ). Since I knew it would be pretty late before I could get home, I suggested that he make himself at home and help himself to anything that was in the refrigerator.

Two hours later my friend phoned me from the house. At the moment, he said, he was listening to some of my records after having had a delicious meal. Now, he said, he was drinking a glass of orange juice. When I asked him if he had had any difficulty finding the house, he answered that the only problem was that he had not been able to find the key under the doormat, but luckily, the living room window by the apple tree had been left open and he had climbed in through the window. I listened to all this in great surprise. There is no apple tree outside my window, but there is one by the living room window of my next door neighbor's house!

¡¾ÌâÄ¿¡¿My grandma whom we all called Nanny was a solid, first-generation, Italian immigrant. She came to this country with her family on a tiny ship during World War I when she was only 8 years old. During the trip she survived stormy seas£¬little food, and an attack by a German U-boat. After getting here£¬her large family worked hard to build a new life in America. They never had much money but were rich in love.

One day, when I was about 5 or 6 years old, my parents and brothers went on a trip. It was just me and Nanny in the house for the weekend. Nanny seemed so happy to be taking care of me all by herself. She made me a special breakfast that first morning. However, all I could do was to complain about how the food was not how Mom always made it. Nanny quietly put down the plate and went into the living room. I followed a minute later and saw that she had tears in her eyes. It was the first time I had ever seen my strong and proud grandmother cry and I was the one who had caused it.

I walked over to Nanny, climbed on her lap, and for the first time in my short life I did something else too. I apologized without being told to and asked Nanny to forgive me. She smiled, rubbed my head, and told me I was a good boy even though I didn't feel like one then.

That memory just like my Nanny's love will stay in my heart forever. It is a sign of both strength and wisdom. Asking for forgiveness helps us to learn, to grow, and to love.
