Ignition can occur in various ways. "Snorting," or sniffing the white powder, ensures absorption of the drug into the bloodstream through the mucous membranes. But it also constricts the myriad little blood vessels in these membranes, reduces the blood supply and dries up the nose. With repeated coke use, ulcers form, cartilage is exposed and the nasal septum can be perforated, requiring repairs by plastic surgery. (Savvy users rinse their noses with water after sniffing to wash away the irritants.) To avoid the impurities of street coke and obtain a greater jolt, more users are resorting to freebasing. After dissolving...
...experiences, but after thorough physicals, including blood tests and electrocardiograms, doctors could find nothing wrong with his heart and attributed the pains to a mild gall bladder attack or chest muscle strain. This time, though, Weiner was given a new diagnostic test. Doctors injected a radioactive substance into his bloodstream, then took pictures of his heart with a special camera that detects radioactivity. The pictures revealed that his heart was not getting an adequate supply of blood, and further tests showed that the coronary arteries were blocked in several places. Weiner underwent bypass surgery, which eased his discomfort...
Nuclear Scanning. Using this technique, doctors can examine the heart's pumping performance and check for evidence of obstruction in the coronary arteries. Radioactive isotopes with affinities for certain tissues are injected into the bloodstream. A special imaging device, called a scintillation camera, picks up the gamma rays emitted by the isotopes, and a computer translates the information into pictures. For example, by using thallium 201, an isotope that lodges in healthy heart muscle, doctors can tell if tissue has died as a result of a heart attack and whether blood is flowing freely through the coronary arteries...
Normally sperm are conveyed toward the outside of the body through ducts, the vasa deferentia. In a vasectomy, the ducts are cut, but sperm continue to be manufactured. With the exit passage blocked, the sperm break down and leak into surrounding tissue and possibly into the bloodstream, where they are recognized as "foreign" and attacked by antibodies. Alexander and Clarkson postulate that the resultant sperm-antibody complexes injure the artery walls and accelerate formation of atherosclerotic plaques...
...legendary. It will kick its master when it is annoyed, and spit cud at curious bystanders. Despite its vile temper, the camel is prized for its ability to withstand searing desert temperatures with a bagful of survival tricks. Among them are its unusual abilities to retain water in the bloodstream (with the help of high concentrations of a special kind of albumin), sweat so little that its skin almost always feels dry, and keep out heat with a coat of thick...
