Sixty-three cases with stomach cancer were randomized into 2 groups and observed

the results showed that the count of T lymphocytes in chemotherapy combined with Shenmai injection (SMI) group increased

while in the control group it decreased

the difference being quite significant (P<0.05). The results also showed that the count of OKT1 cells and the OKT4/OKT8 ratio decreased after chemotherapy

but in SMI group both parameters increased in advance

which were higher in the 4th week after chemotherapy than that before chemotherapy. However in the meantime

the count of OKT1 cells and OKT4/OKT8 ratio of control group were still in low level. After chemotherapy the serum interleukin-2 receptor (sIL-2R) level also decreased (P<0.05)

while activities of natural killer cell (NK) and lymphokine activated killer cell (LAK) level increased (P<0.05) in SMI group. But in the control group

although the sIL-2R level had no change

both NK and Lak level decreased significantly (P<0.05). In addition

the difference of IgA

IgM

IgG levels was not significant between these two groups. These results suggested that SMI might improve human immunologic function to facilitate the chemotherapy of patients with stomach cancer.
