Objectives : This study was designed to investigate the effects of Taraxaci Herba (TH) on cell death in breast cancer cells. Methods : In this experiment, the effects of TH on proliferation rates, cell morphology and growth pattern, intracellular reactive oxygen species (ROS) production. In addition, the effects on nuclear condensation, fragmentation and formation of acidic vesicular organelles (AVO) in MCF-7 cells were also investigated. Finally, autophagy related with protein was observed by using western blot method. Results : TH inhibited proliferation of MCF-7 cells, TH elevated intracellular ROS levels significantly. Treatment with TH did not affect nuclear morphologies such as condensation or fragmentation. On the other hand, TH treatment effectively induced AVO. Finally, one of autophagy related with protein, Microtubule-associated proteins 1A/1B light chain 3A (MAP1LC3A, LC3) level was elevated by treatment with TH. Conclusions : These data indicate that TH is able to be used for patient with breast cancer and mechanisms are involved in autophagy through ROS generation.

Objectives : Jigal-san (JGS, 止渴散) has been used in East Asia including Korea, Japan and China for the treatment of breast inflammatory disorders and severe thirst. JGS originated from Euimunpalbeob (醫門八法; Yimenbafa) composed of Lonicerae Flos and Taraxaci Herba. According to previous studies Lonicerae Flos and Taraxaci Herba have an anti-inflammatory effect, respectively. But, there is no studies regarding on the effects of JGS in the immunological activities. The present study evaluated the anti-inflammatory effects of JGS in vitro and in vivo. Methods : Cell viability was evaluated by MTT assay, and NO was evaluated by content of the nitrite content in culture medium. TNF-α, IL-1β and IL-6 were quantified by ELISA. The protein expression of NF-κB, MAPKs, and iNOS were assessed by western blot analysis. Furthermore, the effects of JGS on acute inflammation were observed in rat paw edema model. Results : The JGS ameliorates the LPS-activated changes in the protein expression of NF-κB, p-JNK, and iNOS, as well as the production of NO and pro-inflammatory cytokines. In rat paw edema study, administration of 0.3 and 1.0 g/kg of JGS for 4 consecutive days inhibited the carrageenan (CA)-induced increases of edema and iNOS expression. Conclusions : These results demonstrate that JGS has anti-inflammatory effect in LPS-stimulated RAW 264.7 cells through decreasing the production of inflammatory mediators, via suppression of the NF-κB and MAPK pathways (JNK, not p-38 and ERK). In addition, the results of the CA-induced paw edema indicate that JGS ameliorates an inflammatory edema. Therefore, the present study could provide scientific evidence for the anti-inflammatory effect of JGS as well as the underlying mechanisms.

Objectives : This study was carried out to investigate anti-oxidative effects of Taraxaci Herba (TH) and protective effects on Human HaCaT keratinocyte. Methods : Anti-oxidative effects were measured by estimating the amount of total phenolics and flavonoids. In addition, DPPH free radical scavenging activities were estimated. Protective effects of TH on HaCaT keratinocytes against oxidative stress induced by hydrogen peroxide were also measured. Results : In our results, treatment with TH did not show cytotoxicity on HaCaT keratinocyte beneath the concentration of 200 $\mu$g/ml. 42.64$\pm$1.90 $\mu$g/ml of total phenolics and 28.09$\pm$1.84 $\mu$g/ml of flavonoids was detected from TH ethanol extract. In addition, DPPH free radical scavenging activities of TH were elevated in dose-dependent manner. In addition, The value of half maximal inhibitory concentration (IC$_{50}$) was 165.5 $\mu$g/ml. Finally, TH showed protective effect against cell death of HaCaT cell induced by hydrogen peroxide significantly. Conclusions : In conclusion, these results suggest that TH may have anti-oxidantic action in human skin and also suggest the possibility as cosmetic material.

GD68 is newly developed herb complex prescription. The constituent herbs of GD68 were Massa Medicata Fermentata, Atractylodis Rhizoma Alba, Poria, Zingiberis Siccatum Rhizoma, Crataegi Fructus, Saccarum Granorum, Agastachis Herba, Taraxaci Herba, Perillae Herba, Scutellariae Radix, Astragali Radix, Ginseng Radix, Houttuyniae Herba and Halloysitum Rubrum. The aim of this study was to examine feed value of GD68 in duck. The weight gain of ducks fed with supplemental GD68 high compared to those of the control. The feed intake and mortality of ducks fed with supplemental GD68 low compared to those of the control. The moisture, crude lipid and calorie content of the ducks fed GD68 were decreased, but the crude protein content of the ducks fed GD68 was increased. And we investigated the effect of GD68 on the production of cytokines in human T-cell line, MOLT-4 cells. GD68 plus concanavalin A (Con A) increased the interferon-$\gamma$ and interleukin-2 production compared with Con A alone. These results indicate that the supplemental GD68 may improve the production, meat quality and immunity of ducks.

Glutamate-induced oxidative injury contributes to neuronal degeneration in many central nervous system (CNS) diseases, such as epilepsy and ischemia. Inducible heme oxygenase (HO)-1 acts against oxidants that are thought to play a role in the pathogenesis of these diseases. In the present study, we investigated the neuroprotective effects of the standard extracts of Taraxacum officinale Weber, one of the original plants of Taraxaci Herba, on glutamate-induced oxidative injury in mouse hippocampal HT22 cells. The standard EtOH extract of the aerial parts of T. officinale (NNMBS270) showed significant cytoprotective effects on glutamate-induced neurotoxicity and induced the expression of heme oxygenase (HO)-1 in the mouse hippocampal HT22 cells, while the roots' extract (NNMBS271) did not show neuroprotective effect. These results suggest that the extract of the aerial parts of T. officinale could be an effective candidate for the treatment of ROS-related neurological diseases.
