代谢
银及其化合物可以通过吸入被吸收,而银化合物也可以通过口服和皮肤接触被吸收。银在血液中分布到全身,尤其是肝脏。不溶的银盐转化为可溶的硫化银蛋白盐,与RNA、DNA和蛋白质中的氨基或羧基团结合,或者被抗坏血酸或多巴胺还原成金属银。金属银被氧化,可能会沉积在组织中,导致银质沉着病。银主要通过粪便排出体外。
Silver and its compounds can be absorbed via inhalation, while silver compounds can also be absorbed orally and dermally. It distributes throughout the body in the blood, 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)
