| 摘 要： | in order to elucidate the different resultsobtained in cancer patients with similar condition andsymptoms treated by the same medicinal herbs,an in-vestigation of the utensils used for making decoctionswas carried out.it was found that the decoction madeby mcans of glassware,enamel and earthenware potshad the best effect of Inhibiting the colony formationof human gastric carcinoma cells,the next were thedecoctions made by means of unrefined iron pots,stainless steel pots and copper pots,and the worstwas that made with aluminium pots.It was alsofound that there was no difference between the watercontained in those utensils and normal saline in theinfluence on the colony formation of human gastriccarcinoma cells.Therefore,it is believed that the dif-ference in effect of the decoctions made by means ofdifferent kinds of utensils is not due to the tracedissolution of the utensil materials,but is most likelydue to the occurence of some chemical reactions whilemaking the decoction.That the decoctions made bymeans of different utensils had different peak valuesin the absorption spectrum also supports this pro-position.
