Small in number, Vehicle Smoke Can Overcome Heart Disease

Smoke a motor vehicle is one of the largest contributors to air pollution in urban environments. Motor vehicle exhaust gas is also known to harm health because they contain hazardous chemicals. However, small amounts of hazardous chemicals that could help tackle heart disease.

The study found that the substance carbon monoxide and nitric oxide contained in motor vehicle fumes can widen blood vessels when inhaled in small quantities. Therefore, a scientist in the UK are making experiments to cure heart disease with toxic chemicals.

"The release of toxins into the heart of a small amount will help the body's ability to relax the arteries, making it wider, allowing more blood to pass through," said Prof. Ian Megson as reported by the Daily Mail, Friday (03/08/2012).

The treatment is expected to be beneficial to patients suffering heart attacks and strokes. Currently, experiments are being carried out by the chemists of St Andrews University in collaboration with a team led by prof Megson at the University of Highlands and Islands using pig heart.

Prof Megson use of toxic chemicals by the amount of 1 million times smaller than the amount spent on car exhaust fumes. Very small amount of this when sent to a particular region can have a healthy heart

"At this time the experiment is at a very early stage, but has great potential. There are many heart patients out there who could benefit from this treatment," said Megson prof.

The team of scientists from St Andrews will begin to create a material called 'metal-organic frameworks' for charged particles of carbon monoxide, nitric oxide and hydrogen sulfide. Within three months, the material will be handed over to Prof Megson and the team will try to figure out how to inject molecules into the heart and measure its impact.

Metal-organic frameworks are designed for gas discharged into the body immediately when touching body fluids. Once tested in pigs, the experiment will then be addressed in patients with heart disease who were treated with stenting methods, namely the insertion of the metal to widen a blocked artery.

"Carbon monoxide and nitric oxide found in car exhaust fumes are also found in the body in small amounts. However, gas is a substance that is very difficult to handle and thus require a long time to find a way to keep it," prof said Megson.
