Toxic Gas May Help Transplants

It would seem that scientists say they have developed a safe method of administering the toxic gas carbon monoxide (CO) in a way that could help organ transplant patients. Even though too much of the gas is deadly, minute doses help widen blood vessels and cut inflammation. This, in turn, could boost the survival chances of donor organs. The Sheffield University scientists have devised a way to release targeted small doses of CO using carrier molecules. They say lab tests have been promising and hope to start human trials by 2010.
