Garlic may protect the heart after heart surgery

10.09.2002


Raw garlic consumption may help limit the damage done to the heart after surgery because if its natural antioxidant properties, according to a new study published in BMC Pharmacology.



After a heart attack it is important to restore the flow of blood to the heart so that damage to the heart muscle can be minimised. However, the return of blood flow can paradoxically cause further damage, so called “ischemic-reperfusion injury, due to the release of free radicals. Free radicals cause oxidative stress to the heart cells, resulting in reduced cardiac function and irreversible tissue injury. This can be potentially fatal to patients undergoing heart surgery to remove clots or repair heart defects.

Antioxidants, which can “mop up” free radicals before they do any harm, have been shown to reduce the severity of damage to the heart. However, the therapeutic use of antioxidants is limited by their toxicity. In light of several recent studies showing that garlic can limit the depletion of natural heart antioxidants, a research team from India designed a study to investigate whether garlic could protect against oxidative stress in rats.


The team found that regular consumption of raw garlic prevented oxidative stress and the resulting tissue damage. Rats that were given a consistent diet of garlic were found to have much higher levels of antioxidants and lower levels of the chemicals that accompany oxidative stress. The damage to their hearts following ischemic-reperfusion injury was also significantly lower. Further studies in humans are needed, but the authors conclude that garlic has important potential to save the lives of patients undergoing heart surgery.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
