对１３１头牛采用三种不同植黄方法，研究影响牛黄形成、增产的有关因素及牛黄形成机制。三种植黄方法牛胆汁中的胆汁酸、胆汁钙、胆红素、ＰＨ值均降低。牛胆囊内植黄期间胆汁粘蛋白、总蛋白含量升高（Ｐ＜０．０１），胆汁粘度增大（Ｐ＜０．０５）；在牛腹腔模拟胆囊内（以下简称ＡＧ）和牛双胆囊（以下简称ＤＧ）内植黄期间胆汁粘蛋白、总蛋白含量降低，粘度变小。３种不同植黄方法牛胆囊内胆汁充盈度、胆汁郁滞量和胆道内压力不同，牛黄产量差异显著。牛黄形成过程为胆道内胆汁郁滞，胆道内细菌感染和β—Ｇ的作用，游离胆红素（ＵＣＢ）与Ｃａ￣（２＋）结合后，在粘多糖作用下形成胆红素钙粘多糖高分子多聚物复合体。
Three different yellow planting methods were applied to 131 cows to study the factors that affect the formation and yield of bezoar and the mechanism of bezoar formation. The bile acid, bile calcium, bilirubin, and pH in the bile of the three planting methods were all reduced. The content of bile mucin and total protein increased during the gallbladder gallbladder (P<0.01), and the bile viscosity increased (P<0.05). The intraperitoneal gallbladder (AG) and bovine double gallbladder were simulated in bovine abdominal cavity. In the following referred to as DG), the contents of bile mucin and total protein were reduced and the viscosity was decreased during the yellow planting. Three kinds of different methods of yellow planting gallbladder gallbladder filling degree, the amount of biliary stagnation and biliary pressure is different, the yield of bovine difference is significant. The bezoar formation process is biliary biliary stagnation, biliary bacterial infection and β-G, and the combination of free bilirubin (UCB) and Ca ̄(2+) forms bilirubin cadmium polysaccharide under the action of mucopolysaccharides.
