THE EFFECTS OF COMPOUND ANTI-TUMOR GRANULES ON GROWTH INHIBITION AND EXPRESSION OF p53 AND PCNA IN MICE BEARING SARCOMA 180 / 解放军医学杂志

ABSTRACT

To study the anti tumor effect of "Compound" granules on mice bearing sarcoma 180 and its possible mechanism, We observed the effect of "Compound" granules on tumor weight and expression of p53 and PCNA in mice bearing sarcoma 180 by means of immunohisto chemistry. After treatment with "Compound" anti tumor granules, anti tumor granules (Ⅰ,Ⅱ,Ⅲ) and CTX, the results showed that "Compound" granules and the other four drugs could inhibit sarcoma 180 growth to various extent, and the rates of inhibition were 20 31%, 6 56%, 15 0%, 19 06% and 30 3%, respectively. Meanwhile,we found the expression of p53 and PCNA in mice bearing sarcoma 180 was affected in various groups.It suggested that compound anti tumor granules had antitumor effect and its possible mechanism might be associated with inhibition the expression of mutate p53 and PCNA.
