代谢
氰化物可以通过口服、吸入和皮肤途径迅速吸收,并分布到全身。氰化物主要通过罗丹酶或3-巯基丙酸硫转移酶代谢成硫氰酸盐。氰化物代谢物通过尿液排出。银化合物也可以通过口服和皮肤吸收。它在血液中分布到全身,尤其是肝脏。不溶性的银盐转化为可溶性的银硫化蛋白酸盐,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。金属银被氧化后可能会沉积在组织中,导致皮肤发蓝(阿蕊吉亚)。银主要通过粪便排出体外。(L808, L96)
Cyanide is rapidly alsorbed through oral, inhalation, and dermal routes and distributed throughout the body. Cyanide is mainly metabolized into thiocyanate by either rhodanese or 3-mercaptopyruvate sulfur transferase. Cyanide metabolites are excreted in the urine. 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, L96)
