RESEARCH into the way vitamins help some people stay healthy will take

a major step forward today.

A Sweetheart Appeal aims to raise more than #55,000 to buy specialist

equipment to let scientists explore why some people can absorb

sufficient vitamin C and E from their diet while others do not.

The equipment will enable heart and lung specialists at St Thomas's

Hospital in London to measure minute quantities of the vitamins in

tissue.

Specialists in the Rayne Institute at the hospital hope to identify

the way in which the vitamins exert beneficial effects, especially in

critically ill babies.

They were among the first to recognise the potential for using

vitamins C and E to fight lung disease. They are now studying how

vitamins get to the cells of the heart and lungs and why a shortage can

cause tissue damage.

Professor David Hearse, director of St Thomas's hospital heart

research unit, said: ''We have found there is great scope for boosting

the body's natural reserves of vitamins C and E and, by doing this, we

can help reduce the heart and lung injury using naturally-occurring

materials.''

His colleague Dr Frank J. Kelly said: ''In order to continue our fight

against heart and lung disease, especially in premature babies and

people with cystic fibrosis, we must continue with this vital

research.''

Vitamin C can be found in fruits such as oranges, apples, and

grapefruits and vitamin E is found in tomatoes, broccoli, and cabbage.
