小编摘要:大蒜对人体有很多好处,但是对心脏的好处是怎样的呢?一起来看看!

导读:研究表明,大蒜可以保护心脏,葱头含有一种能够预防心脏组织受损的物质,因此能预防心脏病的发作。这种物质叫做三硫化二烯丙基,能释放出硫化氢,而小剂量的硫化氢对心脏是有益的。通常情况下,硫化氢是一种不稳定且易挥发的气体。治疗只能通过注射进行,非常地不便。然而现在有了蒜油,问题就迎刃而解了。

Garlic may provide protection against heart damage as well as vampires, research suggests.

The pungent bulb contains an ingredient that has the power to prevent the destruction of heart tissue which can lead to heart attacks.

Scientists tested the compound, diallyl trisulfide, on mice at risk of heart damage from blocked coronary arteries.

Treatment just before blood flow was restored reduced the amount of heart tissue damaged by almost two-thirds.

Diallyl trisulfide releases hydrogen sulphide, which has previously been shown to protect heart tissue in low concentrations.

Researchers at Emory University School of Medicine in the United States have turned to diallyl trisulfide, a garlic oil component, as a way to deliver the benefits of hydrogen sulphide to the heart.

Normally the unstable and volatile gas is difficult to deliver as a therapy because it needs to be injected. Now, thanks to garlic oil, it can be administered orally.

Doctors could use diallyl trisulfide in many of the situations where researchers have proposed using hydrogen sulphide.

David Lefer, professor of surgery at Emory University School of Medicine, said: 'We are now performing studies with orally active drugs that release hydrogen sulphide. 

'This could avoid the need to inject sulphide-delivery drugs outside of an emergency situation.'

Researchers blocked the coronary arteries of mice for 45 minutes, simulating a heart attack, and gave them diallyl sulphide just before blood flow was restored.

The compound reduced the proportion of damaged heart tissue in the area at risk by 61 per cent, compared with untreated animals.

The findings were presented today at the American Heart Association's Scientific Sessions meeting in Orlando, Florida.

Further research reported by the team suggests diallyl trisulfide could also reduce heart enlargement caused by heart failure.
