研究了１９１例人体透明质酸（ＨＡ），发现胚胎组织中ＨＡ含量为（２０３８．３９±３３６．５１μｇ／Ｌ），新生儿血清ＨＡ值为７２０．８１±３８５．７６１１９／Ｌ，随着年龄增大血清ＨＡ逐渐下降，大约６月龄后血清ＨＡ较稳定地保持在４５．９２±３５．９２μｇ／Ｌ水平；肿瘤患者血清ＨＡ增高，中枢神经系统肿瘤脑脊液中ＨＡ显著增高。由于ＨＡ在新生儿中存在着胚胎现象，所以成年肿瘤患者血液或脑脊液中ＨＡ增高可能与“癌胚现象”有关。
191 cases of human hyaluronic acid (HA) were studied. The content of HA in embryonic tissues was (2038.39±336.51 μg/L), and the serum HA of newborns was 720.81±385.76119/L. Increased serum HA gradually decreased. Serum HA remained stable at 45.92±35.92μg/L after approximately 6 months of age; HA in serum of tumor patients increased, and HA in cerebrospinal fluid of central nervous system tumors increased significantly. Because of the embryonic phenomenon of HA in neonates, the increase of HA in the blood or cerebrospinal fluid of adult cancer patients may be related to the “carcinoembryonic phenomenon.”
