　　Los Angeles cabinet-maker Edward Stewart may be a modern Dr Frankenstein. In 1959, he claims, he restored a dead friend to life with a simple technique. He opened the dead man’s chest,
rubbed his heart with a “secret, life-giving” plant juice, then stimulated the heartbeat with 110 volts (伏) of electricity. The friend, says Stewart, has been living in Hawaii ever since.
　　Stewart also claims his revivification (复活) technique works on the small animals he suffocates (窒息) in jars in his garage. It takes three hours to revive a dead mouse, he reports, and five hours for a small dog. “Sometimes,” he adds, “I buy those little chicken hearts in the supermarket, and I make them beat again using my plant juice before I cook them for dinner.”
　　According to Stewart, he discovered the plant juice one day while cutting hedges (树篱) around his former home in Hawaii. Juice from one of the plants splattered onto his wrist, he says, and he suddenly noticed the skin begin to twitch. Nevertheless, he adds, he can’t reveal the name of the plant. “When the juice is zapped with electricity,” he says, “it gives off a deadly gas.”
To promote his idea, Stewart has spent the past decade sending his papers to the University of California, the Army, and a number of government agencies. One scientist who evaluated the concept was Lynn Eldridge, of the Jerry Lewis Neuromuscular Research Center, in Los Angles. She says Stewart may not be joking. “The extracts (提炼物) from plants like belladonna are used to supply nutrients to human organs, which must be kept alive while traveling to a transplant (移植). So Stewart might cut the heart out of a mouse and keep it alive with plant juice. But this effect is short lived, and the organ must be placed into a healthy body or it dies. It is impossible to place a live organ in a dead body and expect it to revive every other organ in that body. I think Stewart has observed a basic scientific phenomenon, but his explanation is crazy.”
　　Stewart recently discovered he had a cancerous growth. Though he admits he could leave instructions for someone to revive him should he die, he still goes for radiation treatment.
　　“If something went wrong with the plant juice,” he says, “I wouldn’t be around to perfect it and give it mankind. Besides”, he claims, “government investigators are watching my garage. They’ve told me not to experiment on humans, which is a real shame.”
