Total hemolytic complement activity (CH50) was compared in sera from normal and tumor-bearing hamsters. CH50 ranged from 160-216 in normal animals and from 82 to 152 in tumor-bearing animals. Preliminary screening assays indicated that of 9 complement components assayed, only C2 and C4 showed differences in titer in both normal and tumor-bearer sera. In an expanded study, examination of sera from 12 normal and 14 tumor-bearing hamsters showed that the mean C4 and C2 levels were approximately 88 and 70% below those seen in normal sera, respectively.
比较了正常仓鼠和荷瘤仓鼠血清中的总溶血补体活性（CH50）。正常动物的CH50范围为160 - 216，荷瘤动物的CH50范围为82至152。初步筛选试验表明，在所检测的9种补体成分中，只有C2和C4在正常血清和荷瘤血清中的滴度存在差异。在一项扩展研究中，对12只正常仓鼠和14只荷瘤仓鼠的血清进行检测，结果显示，C4和C2的平均水平分别比正常血清中的水平低约88%和70%。
