More asthma research yields hopeful new controls
For quite some time it has been known that calcium plays a major role in muscle contraction. A number of calcium-altering medicines are used to help heart problems and hypertension by relaxing the smooth muscle found in the heart and arteries. Now there may be an application to asthma.

A recent British study examined the use of a…
