Amphotericin B两性霉素B
amphoteric (adj.)
of a chemical compound, "capable of reacting either as an acid or as a base," 1832, from Greek amphoteros "each or both of two," a variant of amphō "both" that replaced the earlier word. It is identical with Latin ambo and ultimately from the source of amphi- (q.v.). Other languages have the word without the nasal (Old Church Slavonic oba, Lithuanian abu) and Germanic has it without the initial vowel (Gothic bai). De Vaan writes, "There is no overall explanation for the forms, but connection with [amphi] seems clear."
一种化合物的缩写,“能够作为酸或碱发生反应”,1832 年,源自希腊语amphoteros “每个或两个”,是amphō “两者”的变体,取代了之前的单词。它与拉丁语ambo相同,最终源自amphi- (qv)。其他语言有没有鼻音的单词(古教会斯拉夫语oba 、立陶宛语abu ),日耳曼语有没有声母元音的单词(哥特语bai )。德万写道:“对于这些形式没有全面的解释,但与 [amphi] 的联系似乎很清楚。”
amphi-
before a vowel amph-, word-forming element meaning "on both sides, of both kinds; on all sides, all around," from Greek amphi (prep., adv.) "round about, on both sides of, all around; about, regarding," which is cognate with Latin ambi-, both from PIE root *ambhi- "around."
在元音amph-之前,构词元素,意思是“在两侧,两种;在所有方面,四周”,来自希腊语amphi (prep.,adv.)“围绕,在两侧,四周;在周围;在两侧;在周围;在周围;在周围;在所有方面。” about、about”,与拉丁语ambi-同源,均来自 PIE 词根*ambi- “around”。
iatrogenic 医源性的
"由医生引起的",1920年,来自 iatro- + -genic。
iatro- 这个词缀的意思是“医生; 医学; 治疗”,源自希腊语 iatros “治疗师,医生”
-iatric
源自希腊语 iatrikos 的拉丁化形式,意为“治愈”,源自 iatros “医生,治疗者”(与 iatreun “医疗”, iasthai “治愈,治疗”相关); 其起源不确定,可能源自 iaomai “治愈”,与 iaino “热,温暖,欢呼”相关,可能源自一个意为“使活跃,使有生气”的词根。
弓形虫toxoplasmosis
"弓形虫病"是由常见原生动物真核生物 Toxoplasma gondii(存在于猫粪便、污染食物等中)感染引起的疾病。该词于1951年出现,由 -osis 和 toxoplasma(1913年)组成,1909年在法语中创造,源自希腊语 toxon “弓,弧形”,指该生物的新月形状(参见 toxic),加上 plasma(参见 plasma)。
附:有关toxic
1660年代,源自法语 toxique,直接源自晚期拉丁语 toxicus “中毒的”,源自拉丁语 toxicum “毒药”,源自希腊语 toxikon (pharmakon) “(箭用)毒药”,源自 toxikon,中性形式为 toxikos “与箭或射箭有关的”,因此与弓有关,源自 toxon “弓”,可能源自斯基泰人的一个词,该词也被借入拉丁语为 taxus “红豆杉”。沃特金斯(Watkins)认为伊朗语 taxša- “弓”可能是一个来源,源自 PIE *tekw- “奔跑,逃跑”。作为名词的用法始于1890年。有毒废物在医学上指“毒素”,在1955年指“化学或放射性废物”。
1660s, "of or pertaining to poisons, poisonous," from French toxique and directly from Late Latin toxicus "poisoned," from Latin toxicum "poison," from Greek toxikon (pharmakon) "(poison) for use on arrows," from toxikon, neuter of toxikos "pertaining to arrows or archery," and thus to a bow, from toxon "bow," which has been regarded as a loan-word from Scythian.
Watkins suggests a possible source in Iranian taxša- "bow" (from PIE *tekw- "to run, flee"). Beekes, pointing to the early attestation of the Greek word, suggests a Pre-Greek origin.
As a noun from 1890. Related: Toxical. Compare intoxicate. Toxic waste is by 1888 in medicine, "toxin;" by 1955 as "chemical or radioactive waste."
