代谢
及其化合物可以通过吸入、口服和皮肤接触被吸收。它们在体内分布,尤其是肝脏。不溶的盐转化为可溶的硫化银蛋白盐,与RNA、DNA和蛋白质中的基或羧基团结合,或者被抗坏血酸儿茶酚胺还原成被氧化,可能会在组织中沉积,导致质沉着病。主要通过粪便排出体外。
Silver and its compounds can be absorbed via inhalation, orally and dermally. It distributes throughout the body, particularily to the liver. Insoluble silver salts are transformed into soluble silver sulfide albuminates, bind to amino or carboxyl groups in RNA, DNA, and proteins, or are reduced to metallic silver by ascorbic acid or catecholamines. Metallic silver is oxidized and may deposit in the tissues, causing arygria. Silver is eliminated primarily in the faeces. (L808)

  • 毒性总结
被氧化并可能在组织中沉积,导致质沉着病。银离子已知可以抑制谷胱甘肽过氧化物酶和Na+,K+-ATP酶的活性,分别干扰催化的巯基氧化还原反应和细胞内离子浓度。纳米颗粒被认为会干扰线粒体呼吸链,导致氧化应激、ATP合成减少和DNA损伤。
Metallic silver is oxidized and may deposit in the tissues, causing arygria. The silver ion is known to inhibit glutathione peroxidase and NA+,K+-ATPase activity, respectively disrupting selenium-catalyzed sulfhydryl oxidation-reduction reactions and intracellular ion concentrations. Silver nanoparticles are believed to disrupt the mitochondrial respiratory chain, causing oxidative stress, reduced ATP synthesis, and DNA damage. (L808, A243, A244, A245, A246)

  • 健康影响
本身对人类并不有毒,但大多数盐都有毒。在大剂量下,及其化合物可以被吸收进入循环系统,并在各种身体组织中沉积,导致质病,这种病症会导致皮肤、眼睛和粘膜呈现蓝灰色的色素沉着。质病是罕见的,尽管据目前所知,这种状况并不会对人的健康造成其他伤害,但它会毁容并且通常是永久性的。质病的轻微形式有时会被误认为是发绀。
Silver itself is not toxic to humans, but most silver salts are. In large doses, silver and compounds containing it can be absorbed into the circulatory system and become deposited in various body tissues, leading to argyria, which results in a blue-grayish pigmentation of the skin, eyes, and mucous membranes. Argyria is rare, and although, so far as known, this condition does not otherwise harm a person's health, it is disfiguring and usually permanent. Mild forms of argyria are sometimes mistaken for cyanosis. (L809)

  • 症状
长时间接触高平的可能会导致一种称为质病的状况,这是一种皮肤和其他身体组织的蓝灰色色素沉着。质病是一种永久性影响,但似乎对健康无害。空气中高的暴露已导致呼吸问题、肺和喉咙刺激以及胃痛。与皮肤的接触可能会导致一些人出现轻微的过敏反应,如皮疹、肿胀和炎症。(L808)
Exposure to high levels of silver for a long period of time may result in a condition called arygria, a blue-gray discoloration of the skin and other body tissues. Argyria is a permanent effect but does not appear to be harmful to health. Exposure to high levels of silver in the air has resulted in breathing problems, lung and throat irritation, and stomach pains. Skin contact with silver can cause mild allergic reactions such as rash, swelling, and inflammation in some people. (L808)

    The present invention relates to a silver/polydiguanide complex and derivatives thereof including silver and polydiguanide having at least two biguanide moieties, wherein the silver is stabilized in an oxidation state of an integer of 0 to 4, a mole ratio between the silver and the polydiguanide is 1: 1-4, an average particle diameter of the complex is micrometer or nanometer, and zeta potential of the complex is greater than or equal to zero, a preparation method thereof, and an antibacterial composition for burns or wounds treatment including the same as an active ingredient. A silver/polydiguanide complex according to the present invention is different from conventional silver/polydiguanide complexes in carbon, hydrogen, and nitrogen contents as well as in structure of silver and polydiguanide, and solubility, is a material that exhibits a very good antibacterial activity due to a much lower minimal inhibitory concentration (MIC) value by 10 to 100 folds or more compared to silver sulfadiazine which is a conventional therapeutic agent for burns, and may be usefully used as an antibacterial composition for burns or wounds treatment.
