The salt of human tears

In the UK, one of London's shopping centers in the free sale of salt came from real human tears. According to sellers, tears evaporated to produce a grain of salt. This unusual seasoning is divided by grades: tears of laughter, tears from onions from sneezing and even anger. However, the British journalists suggest that it is likely a publicity stunt: a small bottle of asking for a total of 30 pounds (370 USD). It was reported earlier that the specialists of the University of California, Irvine made a double discovery. Finding out why the protein contained in tears, has antibacterial properties, they have developed a technology that could make a breakthrough in the fight against cancer. The first who established the presence of proteins antiseptics in human tears, was the Nobel laureate Alexander Fleming. Back in 1922, he discovered that lysozymes have antibacterial properties. However, neither then nor later no one was able to answer the question of how lysozyme manages to destroy harmful bacteria. Before that, a team of scientists at Oxford University invented artificial tears. The researchers believe that their discovery will help millions of people suffering from various eye diseases. Artificial tears are for the people who quickly dries the mucous membrane of the eye due to the fact that the glands produce insufficient amount of tears. However, doctors do not rush to give the green light to artificial tears, because there is a risk of an allergic reaction. After all, the basis for artificial tears serve cow's milk, and many people have been allergic to dairy products.
