Lacy Alexander, associate professor of kinesiology, Penn State, and colleagues have launched a series of studies to examine the role of hydrogen sulfide in preventing and reducing hypertension.
The research, led by Alexander, examined young, healthy people who did not have high blood pressure."We had to start with what happens in healthy subjects before we can turn our attention to what happens with
disease," Alexander said.
"We want to develop treatments to help treat and/or prevent cardiovascular disease by capitalising on this hydrogen sulfide pathway," Alexander said.

"The solutions were directly administered to a very small area of skin about the size of a dime using a technique called microdialysis," Alexander said.
"This technique allows us to give tiny quantities of these solutions directly to the skin where they can interact with the vessels directly. It is a very powerful technique because the solutions do not affect the entire body, and we can essentially perform many different experiments at the same time in one forearm," Alexander said.
However, further investigation is needed, researchers said. "Our future plans include working with hypertensive individuals and also examining the effects of a treatment that gives back a small amount of hydrogen sulfide while treating high blood pressure," Alexander said.
