US researchers are suggesting that the gas responsible for stinking up a room may actually help control blood pressure.
Researchers at Johns Hopkins University, in Maryland, found in a mice study that the gas called hydrogen sulphide is produced by an enzyme in blood vessels. This gas relaxes them and lowers blood pressure. In the study, researchers engineered the mice to be deficient in the enzyme called as CSE.
They found that mice deficient in this enzyme had 20% higher blood pressure readings as compared to normal mice.
"Now we know hydrogen sulphide's role in regulating blood pressure, it may be possible to design drug therapies that enhance its formation as an alternative to the current methods of treatment for hypertension," said researcher Dr Solomon Snyder.
The details of the study appear in the journal Science.
