补中益气汤(HET)可增强免疫功能、抗肿瘤、减轻抗癌药副作用。HET是一有效的生物反应调节剂。给正常小鼠口服HET能增强脾脏NK细胞活性,但对荷瘤所致脾脏NK细胞活性降低无改善作用。HET增强NK细胞活性可能是其抑制肿瘤生长的机制之一。T淋巴细胞表达的粘附分子不仅对细胞间相互作用是重要的,而 Buzhong Yiqi Decoction (HET) can enhance immune function, anti-tumor, and reduce the side effects of anti-cancer drugs. HET is a potent biological response modifier. Oral administration of HET to normal mice enhanced spleen NK cell activity, but did not improve spleen NK cell activity due to tumor-bearing tumors. HET enhances NK cell activity may be one of the mechanisms that inhibit tumor growth. Adhesion molecules expressed on T lymphocytes are not only important for cell-cell interactions, but
