Background: The flowers of Inula japonica (Inulae Flos) have long been used in traditional medicine for the treatment of inflammatory diseases. In the present study, we investigated the anti-inflammatory properties of Inulae Flos Extract (IFE). Methods: The anti-inflammatory effects of IFE against nitric oxide (NO), $PGE_2$, TNF-${\alpha}$, and IL-6 release, as well as NF-${\kappa}B$ and MAP kinase activation were evaluated in RAW 264.7 cells. Results: IFE inhibited the production of NO and the expression of inducible nitric oxide synthase (iNOS) in LPS-stimulated RAW264.7 cells. In addition, IFE reduced the release of pro-inflammatory cytokines, such as TNF-${\alpha}$ and IL-6. Furthermore, IFE inhibited the NF-${\kappa}B$ activation induced by LPS, which was associated with the abrogation of $I{\kappa}B-{\alpha}$ degradation and subsequent decreases in nuclear p65 and p50 levels. Moreover, the phosphorylation of ERK, JNK, and p38 MAP kinases in LPS-stimulated RAW 264.7 cells was suppressed by IFE in a dose-dependent manner. Conclusion: These results suggest that the anti-inflammation activities of IFE might be attributed to the inhibition of NO, iNOS and cytokine expression through the down-regulation of NF-${\kappa}B$ activation via suppression of $I{\kappa}B{\alpha}$ and MAP kinase phosphorylation in macrophages.

Objectives : This experiment was designed to assess the single oral toxicity of Ethanol Extract Inulae Flos (IF) ethanol extracts. IF is one of the important herbs to remove phlegmy which is the viscous turbid pathological product that can accumulate in the body, causing a variety of diseases. Nevertheless, there has been a lack of research on the pharmacology toxicity of IF. Methods : In this study, IF was orally administered to 5 weeks ICR mice as an oral dose of 2,000 or 3,000 or 5,000 mg/kg. The condition of the mice was observed for 14 days and their weights were measured every two days. Results : None of the mice died for 14 days. The abnormal clinical symptoms and anatomical signs of toxicity were not found in any treatment groups. The gain of net body weight was observed. There was also no significant difference in the organ weight. The serum biochemistry and hematological analysis showed a decrease in BUN, red blood cells, white blood cells and platelets although within the normal ranges. Conclusions : These results suggest that the 50% lethal dose of IF is more than 5,000 mg/kg. This could be thought that IF is a safe drug without acute toxicity and side effects. However, IF showed some weight loss and change in blood test, so it will need to be careful when using it for high doses.

Background: Lung cancer, the most common malignant disease worldwide, is the predominant cause of cancer deaths, particularly amongst men. Therefore, various researchers have focused on the growth inhibitory effects of medicinal plants used in traditional Korean medicine. This study aimed to investigate the growth inhibitory effects of ethanol extracts of Rubiae radix, Inulae flos, Nelumbinis receptaculum, Astilbe radix, and Lagerstroemia flos on NCI-H1229 cells. Method and Results: The viability of NCI-H1229 cells was evaluated in vitro using an MTS assay. Treatment with the ethanol extracts of the selected medicinal plants at $500{\mu}g/m{\ell}$ reduced NCI-H1229 cell viability and increased apoptotic cell death and caspase-3 activation. In addition, treatment with ethanol extracts of Inulae flos and Astilbe radix increases DNA fragmentation, as measured by the TUNEL assay. Conclusions: These results indicated that ethanol extracts of Rubiae radix, Inulae flos, Nelumbinis receptaculum, Astilbe radix, and Lagerstroemia flos exhibited growth inhibitory effects, inducing apoptotic cell death, DNA fragmentation and caspase-3 activation in NCI-H1229 cells. Therefore, these medicinal plant extracts may be used in the development of natural medicines to inhibit the growth of lung cancers. However, further study is needed to determine the active ingredients of the ethanol extracts from medicinal plants that are reposible for the inhibitory effect on lung cancer cell grwoth.

Background: Inula japonica Thunb. is a plant belonging to the family compositae. Inulae flos (flower of I. britannica var. chinensis Regal.) is the dried flower of I. japonica Thunb. and contains various flavonoids (patulitrin, nepitrin and kaempferol), which have been utilized in traditional oriental medicine to treat nausea, phlegm, and coughs. However, ethanol extract of I. britannica (IJE) has not been previously studied for its use in cancer treatment, and its effects on oxidative stress, or inflammation. Thus, the present study investigated the anti-oxidant, anti-inflammatory, and anti-colorectal cancer effects of IJE using RAW264.7 and HCT-116 cells, which are human colorectal cancer cell line. Methods and Results: IJE contained flavonoids ($80.95{\pm}5.3mg/g$) and polyphenols ($310.53{\pm}10.6mg/g$). Moreover, it reduced lipopolysaccharide (LPS)-induced nitric oxide (NO) production and $H_2O_2$-induced oxidative stress by decreasing reactive oxygen species (ROS) levels. Additionally, the $500{\mu}g/m{\ell}$ IJE treatment increased caspase-3 activity and apoptotic cell death in HCT-116 cells. Conclusions: These results demonstrate that the anti-cancer effect of IJE against human colorectal cancer cells involves caspase-3 activation and apoptotic cell death. IJE also inhibited LPS-induced NO production, and $H_2O_2$-induced oxidative stress in RAW264.7 cells. However, further studies are required to explore how IJE treatment regulates signal transduction in NO and ROS production.

The aim of this study was to determine whether britanin, isolated from the flowers of Inula japonica (Inulae Flos), modulates the generation of allergic inflammatory mediators in activated mast cells. To understand the biological activity of britanin, the authors investigated its effects on the generation of prostaglandin $D_2$ ($PGD_2$), leukotriene $C_4$ ($LTC_4$), and degranulation in IgE/Ag-induced bone marrow-derived mast cells (BMMCs). Britanin dose dependently inhibited degranulation and the generations of $PGD_2$ and $LTC_4$ in BMMCs. Biochemical analyses of IgE/Ag-mediated signaling pathways demonstrated that britanin suppressed the phosphorylation of Syk kinase and multiple downstream signaling processes, including phospholipase $C{\gamma}1$ ($PLC{\gamma}1$)-mediated calcium influx, the activation of mitogen-activated protein kinases (MAPKs; extracellular signal-regulated kinase 1/2, c-Jun $NH_2$-terminal kinase and p38), and the nuclear factor-${\kappa}B$ ($NF-{\kappa}B$) pathway. Taken together, the findings of this study suggest britanin suppresses degranulation and eicosanoid generation by inhibiting the Syk-dependent pathway and britanin might be useful for the treatment of allergic inflammatory diseases.

Objectives : This study aimed to investigate the anti-ulcer effect of an standardized herbal extracts mixture of Inulae Flos and Paeoniae Radix (HT074) on acidified ethanol induced gastric injury and its potential mechanisms. Methods : Antioxidant activities of HT074 and its constituents were measured by DPPH (2,2-Diphenyl-1-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging capacity. After the oral administration of HT074 at doses of 100, 300 mg/kg twice per day for 14 days, Gastric lesions were induced by oral administration of acidified ethanol in Sprague Dawley rats. Oxidative stress markers, such as super oxide dismutase (SOD) activity, concentrations of catalase (CAT) and glutathione (GSH) were measured in gastric mucosal tissues. Additionally, the expression of human mucin gene, Mucin 5AC (MUC5AC) mRNA in gastric mucosal tissues was measured. Results : HT074 showed dose dependent radical scavenging activities against DPPH and ABTS radicals. Oral administration of HT074 300 mg/kg for 14 consecutive days significantly decreased gastric lesions and histological damages induced by HCl/EtOH in rats. HT074 treatment significantly increased the activity of SOD (300 mg/kg) and concentration of GSH (100 and 300 mg/kg), however catalase concentration was not significantly increased. MUC5AC mRNA expression was significantly increased by HT074 100, 300 mg/kg treatment. Conclusions : HT074 protects the gastric mucosa from oxidative stress caused by acidified ethanol by increasing the activity of SOD, concentration of GSH and mucin biosynthesis. These findings suggest that HT074 could be an effective candidate for prevention and treatment of gastritis and gastric ulcer.
