含汞矿物药是指以汞及其化合物为主要成分的一类矿物药,主要有朱砂、银朱、红粉、轻粉、白降丹等,其以HgS、HgO、Hg_2Cl_2、HgCl_2等汞化物形式存在。它们的毒性与其溶解度有关,硫化汞类溶解度较小,因此毒性较小常可内服。氧化汞类、氯化汞类溶解度较大,毒性亦较大,一般仅作外用。一、汞类矿物药的药理作用汞离子(Hg~(2+))可以沉淀蛋白质,可与机体局部组织中的蛋白质生成变性蛋白盐沉淀,因而不同程度地产生收敛硬化作用。反
Mercury-containing mineral medicines refer to a group of mineral medicines containing mercury and its compounds as the main components, mainly including cinnabar, silver jujube, red powder, light powder, and white dropdan, etc., which are in the form of HgS, HgO, Hg 2 Cl 2 , HgCl 2 and other amalgams. exist. Their toxicity is related to their solubility. Mercury sulphide has less solubility, so the toxicity is less often can be taken orally. Mercuric oxides and mercuric chlorides have relatively high solubility and toxicity and are generally used only for external use. First, the pharmacological effects of mercury mineral drugs Hg 2+ (Hg 2+ ) can precipitate proteins that can precipitate with protein-generated denatured protein salts in the body tissues, thus resulting in a convergence hardening effect to varying degrees. anti-
