【摘要】 <正> 天然牛黄(natural ox gallstone)为牛的胆结石,由于产量极少,供求困难,国内于1956年参照天然牛黄的主要成分制成人工牛黄(artificial ox gallstone),作为天然牛黄的代用品。从1974年以来,很多省区如吉林、广东、内蒙古等都先后进行了人工培育牛黄的试验,并试验成功培育牛黄(cultured ox gallstone)。其方法是用手术在牛胆囊内植入异物为核,促使胆汁成分的沉积与结石的形成,经过一段时间后,将异物取出,上面的沉积物即为培育牛黄。本文目的是探讨天然牛黄与培育牛黄的结构特征。更多还原

【Abstract】 Four samples of natural ox gallstone and seven samples of cultured ox gallstone were observed and compared by scanning electron microscopy. The four natural. ox gallstones showed a special porous strueture. Through analysis of the content of bilirubin (BR), cholic acid (CA), deoxycholic acid (DA) and cholesterol (CS) present in these ox-gallstones, the similarity of the cultured ox-gallstone to the natural ones was found to be proportional to the content of bilirubin and inversely proportional to the content of cholic acid and deoxycholic acid. this relation can be expressed by the bilirubin ratio BR/(CA+DA).更多还原
