Scientist's expected invention produces the instrument that can measure pain
Pain is a kind of human most basic feelings, very difficult to be defined. Say, pain is that the organism damages a kind of unpleasant response of emerging to the tissue on the encyclopaedia. If the E.T. sees this definition, certain to be confused, can't find this out " L Unpleasant " R Feels that what it should be one kind on earth.
Usually think, pain is a kind of self-protection mechanism of the human body. One feels pain, must be where to the question happen. A kind of human parasite is called " L The nematode of dragon of Medina " (GuineaWorm) ,Have utilized the keenlying feel of people very cleverly. Will prick the skin when the female worm is ripe, and punish and secrete one kind on the wound strongly to tingle, stimulate nerve of people, keenlying feel like let people produce, fire, can't help, soak, stop the pain in ink wound. The female worm will squirt a large number of worm's ovums at once once meeting water, if someone will be infected after drinking this kind of water, the nematode of dragon of Medina spreads in the crowd like this.
This kind of insect only lays eggs once every year generally, other time hide under the host's skin. Not in order to be felt pain, it will secrete a opium material, the paralysis person's nerve. The the intersection of insect and president reach more than 1 meters long after the one year, can great majority feel its existence people that is infect, it is obvious how terrible this kind of opium material is.
Medina why nematode want, it hides one to be long in year in human body dragon? In fact it is waiting for the appropriate spread chance . Medina dragon nematode most terrible infectious disease, area of Africa, once, and rainfall of Africa so as to annual for cycle usually, the area of many rain will usually have one dry season every year, the arid area will usually have a rainy season every year. The water level among the pond can just reach the appropriate position at this time only, neither too much nor too little, just meet the need that the nematode of dragon of Medina propagates.
The statistics show, whole world have 350 Wan Medina the intersection of dragon and persons who were injured of nematode still 1986, and this figure was 3128 last year, and all centre in Africa . According to the optimistic estimation, this kind of disease will be the second kind of infectious disease which the mankind eliminates following variola, because it is very simple to prevent its method that is infected, so long as the person infected resists and aches, it is all right not to soak the wound in water.
Then, how on earth to ache the wound which nematode of dragon of Medina breaks by the teeth? Say, have been just like pitched by a blazing needle according to the person who has been ever gripped. Then, is it possible to invent a kind of instrument out and measure the intensity of pain out?
