Researchers in the United States have developed the first wirelessly controlled

Researchers in the United States have developed thefirst wirelessly controlled device that can supply a drug directly into thebody. A small chip is implanted (植入) under theskin. It contains the medicine, which it releases at preset times. Thedevelopers say the device could improve the lives of millions of people whotake medicine for long-term illnesses. A company called Microchips begandeveloping the device about fifteen years ago. Last month, the company releasedthe results of its first successful tests in humans. The tests took placein Denmark with seven women with osteoporosis（骨质疏松症）.

Osteoporosis causes bones to become weak and breakeasily. The disorder is common among older people especially women. Manypatients have to give themselves daily injection（注射）ofmedicine. One type of treatment requires injections for two years. The patientsstop taking the medicine because of the pain and stress of the injections. As aresult, only twenty-five percent of the patients will go through the entiretwenty-four months of treatment.

The microchip is a few centimeters long. It has smallsections and each section holds a single dose（单次剂量）ofmedicine. The device has to be programmed with the times to release the drug.Doctors will be able to reprogram the device from a computer or even a cellphone.

For osteoporosis, the physician will program thedevice, and the device has the ability to release a dose at a given time, everysingle day. For other diseases, where the physician may want to change thedosing schedule, they will have the ability to wirelessly reprogram that dosingschedule.

The seven women in the study were ages of sixty-fiveto seventy. The researchers say the implants were just as effective as dailyinjections. And they say the medicine amounts were more exact than patientsoften give themselves.
