Tiny amounts of Manuka act honey, apparently as a natural antibiotic, reports scientists from the University of Newcastle in the journal "Frontiers". Using the honey could, for example, infections after operations stop.
The researchers have tested how a combination of the honey is effective in surgical mesh implants. Such networks are used to support approximately in the surgery of inguinal hernias the tissue. At the same time an increased risk of infection, but because it can form on the surface of the network of a bacterial Biofilm.
For the study, the scientists have made such a mesh implant, in which eight layers of Manuka honey with eight layers of a polymer &ndash alternate; each layer only a fraction of a millimeter thick. Electrostatic charges provide a slow release of the honey, allowing the growth of bacteria in the laboratory for up to three weeks was inhibited, including that of pathogens, such as MRSA, staph, and Escherichia coli. In various soft tissue cells, the compatibility of the networks was tested.
Honey the growth of bacteria can stop
Dr. Piergiorgio Gentile, a biomedical engineer at Newcastle University, explains: "The mesh is implanted in the body, to ensure stability, while the inner tissue to heal. Unfortunately, it also provides the perfect surface on which bacteria can grow." By the of honey is set from the network freely, is to be inhibited, the growth of the bacteria and the infection stopped.
Honey was in the ancient – Thousands of years before the discovery of bacteria – for the treatment of infected wounds. It is believed that honey is bacteria-killing properties, because it contains Compounds that the hydrogen peroxide release. Manuka honey, however, in a new Zealand study in 1991, the only type of honey, the abtötete even after the removal of hydrogen peroxide is still bacteria. This is due to the ingredient Methylglyoxal, which has anti-microbial properties.
