|---|---|---|---|
| 설명 | 일산화탄소의 흡입에 의하여 산화헤모글로빈이 카르복시헤모글로빈으로 변화함으로써 일어나는 중독. 중추신경계장애를 일으키고 죽음에 이르기고 한다. 일산화탄소는 탄소를 함유한 유기물이 불완전연소할 때 발생한다. 따라서 제철, 도시가스 제조, 가정에서 발생하며 자동차 배기가스에도 포함되어 있고 가정에서 연료의 연소에 의해서도 생긴다. 일산화탄소를 흡입하면 폐에서 혈액속의 혈색소와 결합하여 일산화탄소헤모글로빈을 형성하고, 이 때문에 혈액의 산소운반능력이 상실되어 내부적인 질식상태에 빠지게 된다. 일산화탄소와 헤모글로빈과의 친화성은 극히 강하여 산소보다 250배의 세기로 결합한다. 사람에 따라 일산화탄소에 대한 감수성이 다르지만, 공기 속에 0.001%만 들어있어도 중독을 일으킨다. 또 0.06%에서는 1시간만 흡입하면 두통을 일으키고 2시간이면 실신한다. 또 0.1%을 경우는 1시간 이내에 실신하고 4시간이면 사망한다. 중독 증세는 조직의 무산소증에 의한 것으로서, 급성중독은 급격히 사망하는 수도 있지만, 대개는 처음에 두통-현기증-귀울림-구역-구토 등이 있고, 사지의 운동이 불가능하게 되며, 다소의 의식이 남아 있어도 그대로 죽음에 이르게 된다. 타각적으로는 얼굴에 홍조를 띠고 전신에 무늬 모양의 발적이 나타나며, 호흡이 가늘고 불규칙하게 된다. 코를 골고 체온이 내려가고 전신의 근육 이온 등이 보이며, 호흡곤란의 증세가 보이지 않는 중에 호흡이 정지하게 된다. |

| health food | A non-medical term defined by the lay public as a food that has little or no preservatives, which has not undergone major processing, enrichment or refinement and which may be grown without pesticides. Health foods have been attributed with the ability to prevent the development of diseases, slow the aging process, and prolong life. (12 Dec 1998) |

| food | 1. What is fed upon; that which goes to support life by being received within, and assimilated by, the organism of an animal or a plant; nutriment; aliment; especially, what is eaten by animals for nourishment. In a physiological sense, true aliment is to be distinguished as that portion of the food which is capable of being digested and absorbed into the blood, thus furnishing nourishment, in distinction from the indigestible matter which passes out through the alimentary canal as faeces. Foods are divided into two main groups: nitrogenous, or proteid, foods, i.e, those which contain nitrogen, and nonnitrogenous, i.e, those which do not contain nitrogen. The latter group embraces the fats and carbohydrates, which collectively are sometimes termed heat producers or respiratory foods, since by oxidation in the body they especially subserve the production of heat. The proteids, on the other hand, are known as plastic foods or tissue formers, since no tissue can be formed without them. These latter terms, however, are misleading, since proteid foods may also give rise to heat both directly and indirectly, and the fats and carbohydrates are useful in other ways than in producing heat. 2. Anything that instructs the intellect, excites the feelings, or molds habits of character; that which nourishes. "This may prove food to my displeasure." (Shak) "In this moment there is life and food For future years." (Wordsworth) Food is often used adjectively or in self-explaining compounds, as in food fish or food-fish, food supply. <zoology> Food vacuole, one of the spaces in the interior of a protozoan in which food is contained, during digestion.
