牛胸腺激素成份5是一种部分纯化的胸腺提出物。临床研究已用于第Ⅰ、Ⅱ期的免疫缺乏的癌症患者。从细胞免疫功能系数上已观察到某些改善情况:与用羊红细胞的玫瑰花瓣形成试验中所测定的情况相同,主要是末梢血中“T”——淋巴细胞显著增加。胸腺素治疗前在体外实验中显示,胸腺素诱导性玫瑰花瓣形成细胞增加,这种情况一般都予示这些患者经胸腺素治疗后,在体内实验时其血行中的“T”细胞也增加。作者指出,虽然在某些患者已显示出临床上的改善,但从这些简易的研究中推断其临床改善就是、或
Bovine Thymus Composition 5 is a partially purified thymic extract. Clinical studies have been applied to immunocompromised cancer patients in stages I and II. Some improvement has been observed from the cellular immune function coefficient: the same as in the assay of rose petal formation in sheep erythrocytes, mainly the peripheral blood “T” - a significant increase in lymphocytes. Prior to thymosin treatment, in vitro experiments showed that thymosin-induced rose petal-forming cells increased, which generally indicates that these patients were treated with thymosin and the number of “T” cells in the blood was increased during the in vivo experiments. The authors point out that although clinical improvement has been shown in some patients, the clinical improvement inferred from these simple studies is, or
