对荷W256大鼠，生兴克癌冲剂20、10、5 g / kg三组的平均瘤重明显低于对照组(P.01，P.05)，生兴克癌冲剂20、10 g / kg组的平均肿瘤抑制率均大于32 %；⑵与空白对照组相比，生兴克癌冲剂20、10 g/ kg能显著地延长移植小鼠白血病P388小鼠的存活天数(P.01)，生兴克癌冲剂20、10 g/ kg对荷白血病P388小鼠生命延长率均在50%以上；⑶与S180荷瘤组相比，生兴克癌冲剂对荷瘤鼠的免疫器官重量、胸腺指数和脾指数有一定的提高趋势，其中生兴克癌冲剂5 g / kg组对荷瘤小鼠的胸腺指数有一定的提高作用(P.05)；⑷与S180荷瘤组相比，生兴克癌冲剂20、10 g /kg组可提高由荷瘤引起的小鼠血清半数溶血素值的降低(P.01)，表明其可提高荷瘤小鼠体液免疫功能；⑸与对照组相比，生兴克癌冲剂20 g /kg组可提高荷S180肉瘤小鼠的免疫吞噬系数α值(P.01)，表明其可提高荷瘤小鼠细胞免疫功能。

The dose enhancement effects and decreasing effects caused by material inhomogeneity were studied quantitatively with a parameter named Dose Perturbation Factor, which was the ratio of the dose at a point in the heterogeneous phantom to the dose of the same spatial location point in the homogeneous phantom. It was showed that the degrees of the dose enhancement or decreasing depended on the energy of radiation, field sizes of the beamlets and compositions of the media. The dose perturbation for high energy X rays is greater than that for low energy X rays. At the same energy condition, the dose perturbation decreased when the field size increased. And the relationship between them was not linear.

模拟结果表明：在小射野情况下，异质组织界面处出现了较大的剂量跃变，剂量扰动效应的强弱程度取决于射线的能量、射野的大小和模体介质的不同等多种因素，高能X射线条件下的剂量扰动效应大于低能X射线条件下的剂量扰动；在入射X射线能量相同的条件下，剂量扰动效应随射野尺寸的减小而增强，并呈现一种非线性关系。
