In 1931, the Wisconsin research team proved the mammal nutrition must the third kind of element is the zinc; in 1961 Ananda S, Prasad and so on reported that "Iranian village sickness", has the short, the reproductive organ maldevelopment, to lack the iron liver splenomegaly, low-spirited, to be addicted to rests and so on sickness, the zinc treatment has the good effect; Various countries also one after another have the zinc denutrition the report which confirmed after the experiment, and discovered that the zinc medicinal preparation treats enteropathy extremity dermatitis to have the special effect.

锌为人体必需的微量元素之一，其作用巨大，正引起社会各界的日益重视，被近代医学界、营养学界喻为人体的"生命之花"、"智慧元素"。1931年，威斯康星研究小组证明哺乳动物营养所必需的第三种元素是锌；1961年Ananda S，Prasad等报告"伊朗乡村病"，有身材矮小、生殖器官发育不良、缺铁性肝脾肿大、精神不振、嗜睡等症，锌治疗有良效；各国也陆续有锌营养缺乏经实验证实的报道，并发现锌剂治疗肠病性肢端皮炎有特效。20世纪70年代末以后，我国各地有大量关于锌缺乏病的报道，以小儿为多见。

After about two Years an odd Circumstance presented it self which put the old Thought of making some Attempt for my Liberty, again in my Head: My Patron lying at Home longer than usual, without fitting out his Ship, which, as I heard, was for want of Money; he used constantly, once or twice a Week, sometimes oftner, if the Weather was fair, to take the Ship's Pinnace, and go Out into the Road a-fishing; and as he always took me and a young Maresco with him to row the Boat, we made him very merry, and I prov'd very dexterous in catching Fish; insomuch that sometimes he would send me with a Moor, one of his Kinsmen, and the Youth the Maresco, as they call'd him, to catch a Dish of Fish for him.

大约两年之后，出现了一个特殊的情况，这使我重新升起了争取自由的希望。这一次，我主人在家里呆的时间比以往长。据说是因为手头缺钱，他没有为自己的船配备出航所必需的设备。在这段时间里，他经常坐一只舢舨去港口外的开放锚地捕鱼；每星期至少一、两次，天气好的话，去的次数更多一些。那只舢舨是他大船上的一只小艇。每次出港捕鱼，他总让我和一个摩尔小孩替他摇船。我们两个小年轻颇能得他的欢心，而我捕鱼也确实有一手，因此，有时他就只叫我与他的一个摩尔族亲戚和那个摩尔小孩一起去替他打点鱼来吃；那个摩尔小孩名叫马列司科。

In dicotyledonous and nongraminaceous plants, NAS synthesizes nicotianamine which is responsible for iron storage and transportation, and the expression of NAS gene is not induced by iron deficiency.

在双子叶和非禾本科单子叶植物中，烟酰胺的主要功能是铁离子的储藏和运输，NAS基因的表达不受缺铁胁迫诱导。
