鸡卵抗体（lgY）理化特性的研究

本文研究了抗脊髓灰质炎病毒Ⅲ型鸡卵抗体的理化特性，实验证明ＩｇＹ的理化特性，实验证明ＩｇＹ在室温条件下能保持活性６个月，经巴氏消毒后抗体活性不丧失，并且具有很好的耐酸性，研究结果提示特异性ＩｇＹ可作为良好的婴幼儿食品添加剂。

La,Ce,Pr,Nd and Sm concentrations in Pu'er tea of Yunnan,China

The rare earth elements contents (La, Ce, Pr, Nd, Sm) in 150 Pu'er tea samples were analyzed by using inductively coupled plasma atomic emission spectroscopy (ICP-AES), to evaluate the safety of Pu'er tea. Among the investigated rare earth elements (REEs), Ce was the highest (35% of the total REEs content) whose concentrations were found to be in the range of 0.11–1.39 mg/kg, whereas that of Sm in the range 0.01–0.21 mg/kg, showing minimum levels (5.2%). La was the second highest element (28%) found in Pu'e...
