Suzumebachi - Sting


The stinger of the Asian giant hornet is about 6 mm (¼ in) in length, and injects an especially potent venom that contains, like many bee and wasp venoms, a cytolytic peptide (specifically, a mastoparan) that can damage tissue by stimulating phospholipase action, in addition to its own intrinsic phospholipase. Masato Ono, an entomologist at Tamagawa University near Tokyo, described the sensation as feeling "like a hot nail being driven into my leg".

An allergic human stung by the giant hornet may die from an allergic reaction to the venom, but the venom contains a neurotoxin called mandaratoxin (MDTX), a single-chain polypeptide with a molecular weight of approximately 20,000 u, which can be lethal even to people who are not allergic if the dose is sufficient. Each year in Japan, the human death toll caused by Asian giant hornet stings is around 30-40.

Famous quotes containing the word sting:

    Marriage has, for its share, usefulness, justice, honour, and constancy; a stale but more durable pleasure. Love is grounded on pleasure alone, and it is indeed more gratifying to the senses, keener and more acute; a pleasure stirred and kept alive by difficulties. There must be a sting and a smart in it. It ceases to be love if it has no shafts and no fire.
    Michel de Montaigne (1533–1592)

    I always put these pert jackanapeses out of countenance by looking extremely grave when they expect that I should laugh at their pleasantries; and by saying Well, and so?—as if they had not done, and that the sting were still to come. This disconcerts them, as they have no resources in themselves, and have but one set of jokes to live upon.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    All this stuff you heard about America not wanting to fight, wanting to stay out of the war, is a lot of horse dung. Americans, traditionally, love to fight. All real Americans love the sting of battle.... Americans play to win all the time. I wouldn’t give a hoot in hell for a man who lost and laughed. That’s why Americans have never lost—and will never lose—a war, because the very thought of losing is hateful to Americans.
    Francis Ford Coppola (b. 1939)
