Abstract:

OBJECTIVE: To study the inhibitory effect of Ganoderma lucidum, the extract of chloroform, the extract of ethyl acetate and the remains after two-time extraction on BEL-7402 and MGC-803 cells and their protective effects on HL-7702 cells pre-and post-exposed to cisplatin (DDP) and various doses of 60Co gamma irradiation.

METHOD: The antitumor activity and protective effects on damaged HL-7702 cells induced by radiotherapy and chemotherapy of ganoderma lucidum were determined by MTT technique.

RESULT: The anticancer activity of the extract of chloroform Ganoderma lucidum was the best: at the concentration of 0.125 mg x mL(-1), the inhibitory rate was over 50%. To the HL-7702 cells damaged by DDP, four kinds of extracts didn't exert restoring effect, but the pretreatment with the extract of chloroform reduced the damaged degree significantly. To the 60Co gamma irradiated HL-7702 cells, only the extract of chloroform exerted restoring effect to some extent when exposed to middle or high dose of irradiation. The pre-administration of four kinds of extracts reduced the damaged degree by radiation.

CONCLUSION: The extract of chloroform exerts notable antitumor effects on cancer cells and protective effects on damaged normal cells induced by radiotherapy and chemotherapy.
