"Good" CHOLESTEROL CAN TRANSFOM THE "evil" BECAUSE OF NERVOUS AIR POLLUTION

Exposure to pollution is not only bad for the lungs. A new study reveals smoke inhalation vehicle pollution can change the "good" cholesterol ( lipoprotein / high-density HDL) appear to be "evil." These changes contribute to the clogging of the arteries , which increases the risk of heart disease.

The research team of scientists from the University of California, Los Angeles (UCLA ) and other institutions found inhaling smoke pollution may alter the structure of HDL in the body. In addition, these activities also activate other components that cause oxidative damage to cells and tissues premature triggering inflammation and hardening of the arteries .

The study, published in the journal Arteriosclerosis , Thrombosis and Vascular Biology conducted a study on mice. The first group of rats exposed to smoke a few hours a day for two weeks. The first group of rats for a week then placed in the cage with the air that has been filtered. The second group with the same treatment, but not placed in cages with filtered air. While the third group received only exposure to filtered air for two weeks. The mice that received exposure to fumes suffered oxidative damage in the blood and the heart . Even the damage can not be repaired after giving exposure to clean air is performed on the first group.

Lead author of the study Dr . Jesus Araujo, professor of medicine and director of environmental cardiology at the David Geffen School of Medicine at UCLA , said the study shows the pollution of the air can increase the HDL dysfunction and activation of the oxidative internally. Therefore , obstruction of vessels that got so bad that trigger heart disease and stroke.

The particulate emissions from vehicle fumes chemicals found wrapped sensitive to free radicals. These particles are known to cause oxidation.

Author of the study and researcher in the division of cardiology at the Geffen School of Medicine at UCLA recommends that people limit exposure to air pollution to reduce the negative impacts.
