Objective : Phyllostachyos Folium (PF) has been used to treat patients with febrile disease consuming the body fluids marked by fever with restlessness, thirst etc. In the theory of herbology, PF can clear away heat and promote the production of the body fluids, relieve restlessness. Recently PF is known to have anti-bacterial, anti-oxidantic effects. Methods : The present study was carried out to investigate the effects of PF on solid tumor in mice in terms of immune-potentiating and direct cytotoxic action of PF in vitro and vivo study. The present author investigated thymocyte and splenocyte proliferation to confirm immune-potentiating activity of PF and also investigated tumor/body weight ratio and survival rates in tumor bearing mice. Result : In this study, administration of PF decreased tumor/body weight ratio significantly, and prolonged survival duration compared to non-treated control. In addition, treatment with PF suppressed proliferation rate of Sarcoma 180 (S-180) cells significantly, and elevated proliferation rates of thymocytes isolated from normal mice. These results were co-related with in vivo study. Conclusion : In conclusion, these results suggest that PF is useful to treat patient with solid tumor, because PF has direct toxic action for tumor cell and immune -potentiating action for T cells. Further study will need to elucidate exact mechanisms related in anti-cancer action of PF.

본 연구에서는 phenol이 암 예방에 어떻게 영향을 미치는가를 규명하고자 시도하였으며 phenol이 TBARS에 미치는 영향, TBRAS와 암과의 상관관계 규명에 촛점을 맞추었다. 식이 phenol이 조직산화와 종양 발생(tumor onset)에 미치는 영향을 측정하기 위하여 영양적으로 우수한 amino acid-based diet와 transgenic mouse model을 이용한 protocol을 사용하였다. Mice는 human lymphotropic virus(type-1) transactivator(texl) gene을 carry하며 동시에 종양이 외불 나타난다. 25마리의 transgenic mice를 대조군, 2, 4, 8 mmol catechin/kg diet 군 및 wine soled 군으로 구분하였으며, 대조군은 catechin과 wine solid를 전혀 주지 않았으며, wine solid 군은 redwine 750 ml/kg을 주었다. Mice는 매일 관찰하여 맨 처음 종양이 발현하는 날짜를 기록하였다. Catechin과 wine solid를 섭취한 mice에서 종양이 발현하는 시기가 대조군보다 유의적으로 낮았으며 더욱이 4 mmol catechin diet 군과 8 mmol catechin diet 군에서는 실험기간동안 각각 1마리에서 종양이 발견되지 않았다. Catechin과 wine solid를 섭취한 mice의 뇌조직과 비장의 TBARS 수준은 대조군 mice의 동일한 조직과 비교하였을 때 유의적으로 낮았다. 또한 조직의 TBARS 수준은 종양 발생과 유의적으로 상관관계가 있었다. 본 연구의 결과는 phenol의 종류에 상관없이 식이 phenol에 조직의 항산화(산화억제)를 통해 암 예방(cancer prevention)에 영향을 미친다는 것을 제시해준다.

Anti-tumor activity of Euphorbia hirta (50 mg/kg and 100 mg/kg) has been evaluated against Ehrlich's ascites carcinoma (EAC) in Swiss albino mice. Intraperitoneal (i.p) administration of Euphorbia hirta was effective in reducing solid tumor mass development induced by EAC cells. It exhibited significant anti-tumor activity in mice, when used at the dose of 100 mg/kg/day i.p., for 14days. The administration of Euphorbia hirta (100 mg/kg/day i.p.) resulted in an increase (P<0.001) of the life span (59.9%) of ascites tumor bearing mice as compared to the control group. After 14 days, on developed tumor masses, Euphorbia hirta administration brought about significant reduction in tumor volume and it reverse the changes in the hematological parameters, responding to tumor inoculation. The results are indicative of the anti-tumor activity of Euphorbia hirta against EAC induced tumor in a dose dependent manner.

Platycodon radix is a dried root of Platycodon grandiflorum (P. grandiflorum) A. DC, a perennial grown on the hills and fields in Korea and Japan, or cultivated in various districts. Recently, P. grandiflorum (Changkil) has been successfully cultivated for more than 20 years and generally has been employed as folk remedy for adult diseases such as hyperlipidemia, hypertension and diabetes. We investigated various biological activities of the extracts from Changkil. When treated in vitro with B16-F1 mouse melanoma cell lines, it showed 100% laminin-binding inhibitory activities at the concentration over 0.125mg/ml. In in vivo test it showed 61.5% reduction of the solid tumor weight transplanted in mice and exhibited anticancer activity of 128% ILS against Sarcoma-180 ascites. It also increased the ratio of positive cells of natural killer cells in lymphocytic composition against Sarcoma-18O ascites and solid tumor transplanted in ICR mice when tests were carried out by FACScan method.
