本文通过体外实验(37℃)探讨了Ca~(2+)对胆红素沉淀的影响,结果表明:Ca~(2+)能明显促进胆红素和粘蛋白沉淀(P<0.01),但对胆汁胆酸的含量影响不大,同时一定浓度的Ca~(2+)能提高胆汁沉淀物中眼红素的含量.本文还比较了胆汁沉淀物与培植牛黄的超微结构及组织化学性质,发现二者基本一致. In this paper, the effect of Ca~(2+) on bilirubin precipitation was investigated in vitro (37°C). The results showed that Ca~(2+) can significantly promote the precipitation of bilirubin and mucin (P<0.01). The effect of bile cholic acid content is not significant, while a certain concentration of Ca 2+ can increase the content of ocular erythrocyte in the bile sediment. This article also compared the ultrastructure and histochemical properties of bile sediment and cultured bovine. Found that the two are basically the same.
