1. Objective This study was aimed to screen the potential antitumor activity of one kinds of Korean medicinal herb extracts against cancer cell lines and to evaluate the growth inhibition effect of L-1210 and S-180 cancer cell lines. 2. Methods It confirmed Anemarrhena asphodeloides extracts to screen the potential antitumor activity. Then, it was extracted with 4 kinds of solvents ; hexane, ethyl acetate, butanol and $H_2O$, and the Growth inhibition effect of these extracts were determined against cancer cell and normal cell. The results were as follows : The IC50(50% inhibitory concentration) values of Anemarrhena asphodeloides extracts were shown to be $253{\mu}g/ml$ against L-1210 cell lines. The IC50 values of ethyl acetate extracts were shown to be $915{\mu}g/ml$ against L-1210 cell lines. The IC50 values of butanol extracts were shown to be $52.3{\mu}g/ml$, $485{\mu}g/ml$ against L-1210, S-180 cell lines, respectively. The butanol extracts were more selectively effective than other extracts to cancer cell lines. 3.

Multidrug resistance(MDR) phenotype is frequently observed in animal and human cancer cell lines selected for in vitro resistance to a single chemotherapeutic agent. It is characterized by the diminished drug accumulation and is related to the drug efflux mechanism in resistant cells. In the present study, adriamycin resistant cells(L1210-$AdR_6$ : $10^{-6}M$ adriamycin, $-AdR_5$ : $10^{-5}M$) and vincristine resistant cells (L1210-$VcR_7$ : $10^{-7}M$ vincristine, $-VcR_6$ : $10^{-6}M$) were produced from mouse lymphoblastic leukemia cell line L1210. Growth profiles of survived cells were observed for 5 days with MTT(thiazolyl blue) assay and resistance was compared with $IC_{50}$(drug concentration of 50% survival reduction in absorbance). Resistant cells proliferated more slowly than sensitive cell. Doubling times were 29.7hr in L1210, 68.7hr in L1210-$AdR_5$ and 58.2hr in $-VcR_6$. MDRs expressed as resistance factor were as follows, L1210-$AdR_5$ was 76.4 times for vincristine, L1210-$VcR_6$ was 96.4 times for adriamycin. The cell membrane proteins with three different M.W. were recognized to be related resistance, 220, 158, and 88 kd in L1210-$AdR_5$, 158, 140 and 88 kd in L1210-$VcR_6$ by SDS-PAG electrophoresis. Cell surface membrane proteins were identified by radio-iodination and autoradiogram, their molecular weights were 158, 72.8, and 42.4 Kd in L1210-$VcR_6$.

The effect of gradient eluted fractions from Et$_2$O extracts of Polyporus umbellatus screlotium was investigated on the viability of leukemia cell lines, K-562, L-1210, HL-60 and U-937 cells. Among those fractions, fraction 2 showed mild cytotoxic effect on L-1210 and HL-60 cells. Fraction 3 showed cytotoxic effect on 4 cell lines, and cytotoxic effect was the most potent on L-1210. The hallmark of apoptosis, DNA fragmentation, also appeared by fraction 3 on L-1210 after 48 hr treatment. Furthermore, this fraction was shown to be able to induce cell death on L-1210 cells by the inhibition of DNA synthesis in [$^3$H]thymidine incorporation test. From these results, P. umbellatus involves a potent chemical component that inhibits the viability of leukemia cell lines, L-1210. Further studies about the components of fraction 3 to function as a apoptosis inducer are necessary.

The present investigation was undertaken to examine the anticancer activity of the methanol extract from Houttuynia cordata on ICR mouse with induced abdominal cancer and L1210 cancer cells. When the methanol extract of Houttuynia cordata (10∼200 $\mu\textrm{g}$/$m\ell$) was administered orally to ICR mouse with abdominal cancer, 47.8% of the best life prolonging effect was obtained. In case of cytotoxicity study (inhibition of cell proliferation) of Houttuynia cordata extract against L1210 cells, $IC_{50}$/ was found to be 62.8 $\mu\textrm{g}$/$m\ell$. In contrast to such considerable toxicity against cancer cell line, the toxicity demonstrated by the identical extract against normal lymphocytes was very meagre as shown to be < 5% compared with 86.5% in case of L1210 cells at the same condition. To get an insight into the reaction mechanism undelying the anticancer activity, $O_2$ion quantity and antioxidant enzyme activities such as superoxide dismiutase (SOD) and glutathione peroxidase (GPx) of L1210 cells in the presence of Houttuynia cordata extract were measured. The increased values of SOD and GPx enzyme activities in addition to the augmented generation of $O_2$ ion in L1210 cells implied that the reactive oxygen species induding $O_2$ion which were presumably induced by Houttuynia cordata extract might have participated in the process of L1210 cells cytotoxicity.
