Abstract
Monocytes (MC), lymphocytes (LC) and Kupffer cells (KC) were isolated respectively from blood and surgical liver samples of patients suffering from hepatocellular carcinoma (HCC). 13 patients were given BCG, mixed bacterium vaccine (MBV) and human white blood cell interferon (IFN), the other 3 patients were not treated with any biological immune stimulants (BIS) and served as controls. The cytostatic and cytotoxic effects of MC and KC on human hepatoma SMMC-7721 (TC) were assayedin vitro and the numbers of T total (Tt), T helper (Th) and T suppressor (Ts) cells were counted using CD monoclonal antibody immunofluorescence. The results were as follows: (1) On the 7th day after the first administration of BIS, the cytostatic and cytotoxic effects of MC on TC showed obvious increase over pre-administration. The activity of BIS was 1–5 times as high as that in the controls. (2) After 3 administrations, the cytostatic effect of MC on TC increased to the normal level (84%), while the controls remained as before (45%). (3) On the 7th day after first administration, cytostatic and cytotoxic effects of KC on TC were 0.5 and 1 times higher respectively than those of the controls. (4) The numbers of Tt and Th of patients given BIS increased continuously; on the contrary Ts decreased in number. These results indicate that combined use of BCG, MBV and IFN can actively enhance the immune anti-hepatoma function of patients suffering from HCC.
