Desensitization is based on the premise that the administration of the allergen will cause the body to produce antibodies that will cancel out the effects of the offending substance when the patient is again exposed to it.
Leo Conway, ., of Denver Colorado, treated his patients with pollen. Dr. Conway reported: "All patients who had taken the antigen [pollen] for three years remained free from all allergy symptoms, no matter where they lived and regardless of diet. Control has been achieved in 100 percent of my earlier cases and the field is ever-expanding.” Since oral feeding of pollen for this use was first perfected in his laboratory, astounding results were obtained. No ill consequences have resulted. Ninety-four percent of all his patients were completely free from allergy symptoms. Of the other six percent, not one followed directions, but even this small percentage were nonetheless partially relieved.
On many ranches, weaned calves go directly from the pasture to the sale barn, where they’re sold at auction, by the pound, to feedlots. The Blairs prefer to own their steers straight through to slaughter and to keep them on the ranch for a couple of months of “backgrounding” before sending them on the 500-mile trip to Poky Feeders. Think of backgrounding as prep school for feedlot life: the animals are confined in a pen, “bunk broken”—taught to eat from a trough—and gradually accustomed to eating a new, unnatural diet of grain. (Grazing cows encounter only tiny amounts of grain, in the form of grass seeds.)
Even though anabolic steroids do not cause the same high as other drugs, they can lead to addiction. Studies have shown that animals will self-administer steroids when they have the chance, just as they do with other addictive drugs. People may continue to abuse steroids despite physical problems, high costs to buy the drugs, and negative effects on their relationships. These behaviors reflect steroids' addictive potential. Research has further found that some steroid users turn to other drugs, such as opioids, to reduce sleep problems and irritability caused by steroids.
