Broccoli Seeds May Prevent Skin Cancer

Vegetables Broccoli is indeed a lot of benefits, in addition to good to eat broccoli can also help skin cells counteract the dangers of ultraviolet radiation. According to U.S. researchers extract of fresh broccoli cabbage seeds, to reduce the red color of the skin and damaged more than a third compared with untreated skin. They conducted experiments on mice, it turns vegetable broccoli extract proven to help skin cells against damage by light.
"This is a first demonstration that human skin cell can be protected directly against a known carcinogen (causes cancer) in humans," said Dr. Paul Talalay of Johns Hopkins University, which the results of study appears in the Proceedings of the National Academy of Sciences.
"This is not a sunscreen,". However, the extract helped fortify skin cells against UV radiation.
Unlike sunscreens, which provide a physical barrier against UV rays by absorbing, blocking or insulate the light, the extract helped boost the production of protective enzymes that prevent ultraviolet damage from UV, Talalay said.
He was and is still studying which is a substances sulforaphane in broccoli sprout extract - for more than 15 years. This research has been shown to prevent tumor development in a number of animals that were given an object causes of cancer. Talalay and his friends have tried it on six people, testing the extract with different doses in some skin pieces, and then exposed to a short pulse of UV radiation sufficient to cause the sun to varying degrees.
They compared the redness which exposed skin with the unaffected. "Redness is a size series of processes that happen in skin which damaged, including DNA damage," Talalay said. At the highest doses, the extract reduced redness and swelling by an average of 37 percent. The impact was long-lasting, Talalay said. "Two days after we stopped, was still an effect," he said. Impacts which happen in volunteers have a wide variation, ranging from 8 percent to 78 percent protection, cause is genetic differences.
"What we've proved is important because it happen in humans," continued Talalay. "How should this be applied to humans - that need More work."

This extract could be useful as an instrument protection against ultraviolet radiation, particularly in people whose immune system is lost with most of them most at risk for skin cancer, such as patients undergoing transplantation (transplant), Talalay said. But this is no substitute for a sunscreen.
"This is not to protect the radiation a penetrate into skin cells." he said.
Skin cancer is the most common cancer in the United States, affects more than 1 million Americans each year, according to the National Cancer Institute. Skin cancer also kills more than 10,000 people each year, representing about 4 percent of our deaths caused by cancer.
