| !!shock!! السلام عليكم وجدت هذا المقال في مجلة SCIENTIFIC AMERICAN العلمية واحببت ان اشارككم بهذه المقتطفات منه والصور البيانيه حيث انه المقال طويل جدا واظن انه قراءته على شاشة الكمبيوتر ستكون مملة وصعبة Whatever the cause—a heart attack, .a car accident, a serious bacterial infection—the glassy-eyed catatonia of a person in shock often portends death. Every year in the U.S. alone, about 500,000 people go into sudden shock, and half die from it. For millions more, it is the final stage of terminal illness. Doctors know a good deal about what causes the condition: very low blood pressure that results in dangerously reduced delivery of blood to tissues. And they know that it kills when the lack of oxygen irreparably damages the brain and other vital organs. They also have a few tools for reversing shock before it goes too far, at least in some people. But all too often treatment is ineffective, especially when a runaway infection is the trigger. Because shock is so devastating, many investigators are aggressively trying to develop better treatments. Yet despite their initial promise, several seemingly helpful drug candidates have failed in recent years. To our great satisfaction, though, a chance discovery we made not long ago has led to a successful therapy. This agent does not cure the conditions that caused the shock, but it is already helping to treat thousands of shock victims. In addition, during the course of our research into this compound, we learned new information about the underlying mechanisms of shock. With luck, our insights and those of others may lead to further advances in treatment Overview/Treating Shock: *Finding better treatments has been exceptionally difficult, as several lines of research and possible drugs have hit dead ends. *Fortuitously, an existing drug is proving highly effective. Traditionally used to prevent bleeding in the esophagus, the hormone vasopressin has unexpectedly turned out to be powerful as a treatment for shock. تحياتي للجميع |
