Honey extraction abrading the surface of the wax with moving chains or bristles or hot knives. This, while messy, makes the process easier than doing this task manually. Some beekeepers will also harvest (before uncapping the honey) the propolis, a resinous material bees gather to glue the frames together; propolis is used for its medicinal properties. Once uncapped, the frames are then placed in a honey extractor, which spins them so that most of the honey is removed by centrifugal force. Care must be taken to ensure that all frames are loaded correctly, as the comb is angled slightly upwards to prevent
Fibrin glue and plasminogen. This glue can be used for repairing dura tears, bronchial fistulas and for achieving hemostasis after spleen and liver trauma. It is also employed in "no sutures" corneal transplantation, pterygium excision with amniotic membrane or conjunctival autograft, and in ocular trauma for corneal or conjunctival defects. It can also be used for skin graft donor site wounds to reduce postoperative pain. Fibrin glue Fibrin glue (also called fibrin sealant) is a surgical formulation used to create a fibrin clot for hemostasis or wound healing. It is made up of fibrinogen (lyophilised pooled human concentrate) and thrombin (bovine, which
