소적보중환(消積保中丸)의 항종양효과(抗腫瘍效果)에 대한 실험적(實驗的) 연구(硏究)

The sprig of Sojekbojungwhan(消積保中丸) has been used for curing as a traditional medicine without any experimental evidence to support the rational basis for their clinical use. This experiment was carried out to evaluate the possible therapeutic or antitumoral effects of Sojekbojungwhan extract against cancer, and to study some mechanisms responsible for its effect. The cytotoxic and antitumor effects were evaluated on human cell lines(A549, hep3B, Caki-1, Sarcoma 180) after esposure to Sojekbojungwhan extract using in ILS, colony forming efficiency and SRB assay which were regarded as a valuable method for cytotoxic and antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows. 1. As a result of exposure to Sojekbojungwhan extract, the proliferation of A549, hep3B, Caki-1, good correlations were shown from the results of SRB assay and those of clogenetic assay. 2. The oral administration of Sojekbojungwhan extact showed significant effects of increase of MST(mean survival time) and ILS(increased life span) depending on the increasing concentration. 3. Against squamous cell carcinoma induced by MCA, Sojekbojungwhan decreased not only the frequency of tumor production but also the number and weight of tumors per tumor bearing mice(TBM). Sojekbojungwhan also significantly suppressed the development of 3LL cell-implanted tumors by frequency and their size, and some developed tumors were regressed by the continuous treatment of Sojekbojungwhan extract into TBM. 4. Sojekbojungwhan extract also increased NK cell activities. According to the above results, it could be suggested that Sojekbojungwhan extract has some antitumor effects.
