- 在大量病因學(xué)研究基礎上，我國學(xué)者提出“中草藥腎病”的命名欠妥，應稱(chēng)之為馬兜鈴酸腎病(Aristolochic Acid Nephropathy，AAN)。Based on a great deal of etiological research, scholars in our country alleged it should be named by "Aristolochic Acid Nephropathy"(AAN) rather than CHN.

- 加工過(guò)程中除了超濾對氨基態(tài)氮(AAN)幾乎沒(méi)有影響外，其它單元操作都可降低果汁中AAN的含量，特別是吸附、濃縮和后巴氏殺菌對其均有明顯的影響。Ultrafiltration (UF) has hardly effect on AAN, however, other unit operations can reduce the content of ANN especially in concentration, adsorption and second pasteurization.
