Selaginella Tamariscina is widely used in the traditional oriental herbal medicine for its anti-inflammatory, anti-cancer effects. The effects of aqueous extracts of Selaginella Tamariscina (ST) on the cell viability and induction of apoptotic cell death were investigated in A549, Raw 264.7, C6-glioma. Jurkat and HL-60 cells. The cell viability after treating with extract of Selaginella Tamariscina was quantified by MTT assay method. The results showed that ST decreased the cell viability in HL-60 and Jurkat cells not in A549, Raw 264.7 and C6-glioma cells. And we also observed the chromatin condensation and DNA fragmentation in HL-60 and Jurkat cells. The enzyme activity of caspase-3, tightly regulated by an apoptosis activating complex, were markedly increased in HL-60 cells treated with the ST by dose-dependent manner. In conclusion, our results suggest that the extract of Selaginella Tamariscina may induce the selective apoptotic cell death in HL-60 and Jurkat cells via activation of caspase-3.

In our previous studies, we reported that Selaginella Tamariscina(ST) induced apoptotic cell death in HL-60 cells selectively. The cell viability after treatment with extract of ST was quantified by MTT assay and trypan bleu exclusion method. The results showed that application with ST in HL-60 induced 40% cell death at the concentration of 400 ㎍/ml. The cancericidic effect of Selaginella Tamariscina was mediated by apoptosis. Thus, HL-60 cells exposed to Selaginella Tamariscina displayed the DNA fragmentation ladder and nucleus chromatin condensation characteristic for apoptosis. The enzyme activity of caspase-3 and actived caspase-3 protein were markedly increased in HL-60 cells treated with the extract of Selaginella Tamariscina. In addition, the extract of Selaginella Tamariscina induced cleavage of PARP, a known substrate for caspase-3. The expression of Bcl-2, anti-apoptotic protein, was decreased by treatment of the aqueous extract of Selaginella Tamariscina in a dose-dependent manner. And the expression of pro-apoptotic Bax protein was increased. In conclusion, our results suggest that the extract of Selaginella Tamariscina may induce the apoptotic death of HL-60 cells via activation of caspase-3, cleavage of PARP protein, depletion of cellular ATP levels and Bcl-2 degradation.

Artocarpus heterophyllus has been used as traditional medicine. This plant is one of the sources of flavonoid. Flavonoid compounds possessed a wide range of biological properties including anticancer. This study was performed to investigate the cytotoxic effect of flavonoids from A. heterophyllus on H460 and MCF-7 cell lines. The interaction of flavonoids and cisplatin against tested cancer cells was also evaluated. MTT assay was used to determine the cytotoxic effect of flavonoid. Isobologram analysis was selected to evaluate the synergistic effect between flavonoid and cisplatin, their interaction was then confirmed using AO/PI staining method. Amongst of flavonoid compounds, artocarpin exhibited strong cytotoxic effect on both MCF-7 and H460 cell lines with IC₅₀ values of 12.53 ㎍/mL (28.73 μM) and 9.77 ㎍/mL (22.40 μM), respectively. This compound enhanced anticancer activity of cisplatin against H460 and MCF-7. The combination produced a synergistic effect on H460 and MCF-7 cell lines with a combination index (CI) values of 0.2 and 0.18, respectively. The AO/PI stained demonstrated that the combination of artocarpin and cisplatin caused morphological changes that indicated apoptosis. Moreover, artocarpanone also significantly increased cytotoxic effect of cisplatin compared to its single concentration with CI below than 1. This result suggested the potency of flavonoid named artocarpin to enhance the anticancer activity of cisplatin on H460 and MCF-7 cell lines.

Aims: To study the effectiveness of human recombinant endostatin injection (Endostar(R)) combined with cisplatin doublets in treating advanced non-small cell lung cancer (NSCLC), and to evaluate outcome by CT perfusion imaging. Methods: From April 2011 to September 2014, 76 patients with advanced NSCLC who were treated with platinum-based doublets were divided into group A (36 patients) and group B (40 patients). Endostar(R) 15mg/day was administered 4 days before chemotherapy and combined with chemotherapy from day 5 in group A, and combined with chemotherapy from the first day in Group B. Endostar(R) in the two groups was injected intravenously for 14 days. Results: Treatment effectiveness in the two groups differed with statistical significance (p<0.05). Effectiveness evaluated by CT perfusion imaging, BF, BV, MTT and PS also demonstrated significant differences (all p<0.05). Adverse reactions in the two groups did not significantly vary (p> 0.05). Conclusions: The response rate with Endostar(R) administered 4 days before chemotherapy and combined with chemotherapy from day 5 in group A was better than Endostar(R) combined with chemotherapy from the first day, and CT perfusion imaging could be a reasonable method for evaluation of patient outcomes.

To aim of this was to observe emodin-mediated cytotoxicity and its influence on Rad51 and ERCC1 expressionin non-small cell lung cancer (NSCLC). NSCLC cells were cultured in vitro with emodin at various concentrations (0, 25, 50, 75 and $100\;{\mu}mol/L$) for 48h and the proliferation inhibition rate was determined by the MTT method. Then, NSCLC were treated with emodin (SK-MES-1 $40\;{\mu}mol/L$, A549 $70\;{\mu}mol/L$) or $20\;{\mu}mol/L$ U0126 (an ERK inhibitor) for 48 h, or with various concentrations of emodin for 48 h and the protein and mRNA expressions of ERCC1 and Rad51 were determined by RT-PCR and Western blot assay, respectively. Emodin exerted a suppressive effect on the proliferation of NSCLC in a concentration dependent manner. Protein and mRNA expression of ERCC1 and Rad51 was also significantly decreased with the dose. Vacuolar degeneration was observed in A549 and SK-MES-1 cell lines after emodin treatment by transmission electron microscopy. Emodin may thus inhibited cell proliferation in NSCLC cells by downregulation ERCC1 and Rad51.

Purpose: This study was conducted to investigate the effects of Hominis Placenta (紫河車) on the growth of human uterine myoma cells and cell apoptosis. Methods: Human uterine leiomyoma cells were cultured and treated with Hominis Placenta extract for 48 hours. Cell proliferation and activity was analyzed by MTT assay. We analyzed the cell cycle of human uterine myoma cells treated Hominis Placenta extract by FACS. Expression of proteins related to cell apoptosis (Bax, Bcl-2), cyclin-D1 and VEGF were evaluated by Western blotting method. Results: The human uterine myoma cells treated by Hominis Placenta extract didn't proliferate below the concentration of $10mg/m{\ell}$. And there was no remarkable difference on cell cycle analysis below the concentration of $10mg/m{\ell}$. The expression of Bax was decreased and the expression of Bcl-2 was increased after the treatment of Hominis Placenta extract. But the expressions of cyclin-D1 and VEGF were increased after the treatment of Hominis Placenta extract. Conclusion: This study suggests that Hominis Placenta induce uterine myoma cell apoptosis and have effect on the myoma cell proliferation in the concentraion below $10mg/m{\ell}$.

Objective : In this study, the ethanol extract from flowers of Lespedeza bicolor was investigated for their dermal bioactive properties related to cosmeceuticals such as depigmentation and radical scavenging effect. Results : The ethanol extract from flowers of Lespedeza bicolor showed considerable radical scavenging activity ($SC_{50}:\;10\;{\mu}g/ml$) and inhibited the production of nitric oxide (NO) in Raw 264.7 macrophages activated with the endotoxin lipopolysaccharide (LPS). Although the proliferation of B16/F10 cells was slightly decreased by the ethanol extract from flowers of Lespedeza bicolor at the concentration of $100\;{\mu}g/ml$, it did not appear necrosis. The ethanol extract from flowers of Lespedeza bicolor down-regulated melanin formation effectively. Methods : The free radical scavenging activity of Lespedeza bicolor was assayed in cell free systems using a stable free radical, 1,l-diphenyl-2-picrylhydrazyl (DPPH). Nitrite accumulated in culture medium was measured as an indicator of NO production using a Griess reaction. Cell viability was measured by MTT assay and melanin content was assessed using the method of Hosei with some modifications. Conclusions : These results suggest that the ethanol extract from flowers of Lespedeza bicolor is a potent depigmetation agent and it may be a candidate for antioxidant and anti-inflammatory agent.

Objectives : This experimental study was performed to investigate the effects of Yeouigeumhwang-san(YUGHS) on anti-inflammation and anti-Propionibacterium acnes. Methods : The cytotoxicity of YUGHS about viability of Raw 264.7 cell was tested by using a colorimetric tetrazolium assay(MTT assay). To investigate the anti-inflammatory effets of YUGHS on LPS-induced macrophage Raw 264.7 cell, we used ELISA kit and Western blots. Inhibitory effects of YUGHS on Propionibactrium acnes were investigated by using paper disk diffusion method. Results : 1. YUGHS has no cytotoxicity under 50 ${\mu}g/ml$ concentration but over 50 ${\mu}g/ml$ has a little cytotoxicity in Raw 264.7 cell. 2. Concentration of 100 ${\mu}g/ml$ YUGHS inhibited the production of NO in the Raw 264.7 cell stimulated with LPS. 3. All concentrations of YUGHS did not inhibit the production of $TNF-{\alpha}$ in the Raw 264.7 cell stimulated with LPS. 4. All concentrations of YUGHS significantly inhibited the production of $PGE_2$ in the Raw 264.7 cell stimulated with LPS. 5. YUGHS did not inhibit the expression of COX-2 but concentration of 50 ${\mu}g/ml$ YUGHS inhibited iNOS expression in the Raw 264.7 cell stimulated with LPS. 6. YUGHS has the effect of blocking $NF-{\kappa}B$ into nucleus in LPS-induced macrophage Raw 264.7 cell 7. YUGHS did not have the inhibitory effect of Propionibactrium acnes. Conclusions : These results indicate that Yeouigeumhwang-san has anti-inflammatory effets. If further study is performed, the use of Yeouigeumhwang-san will be valuable and benificial in the therapy of acnes.
