Methods: In this experiment, the anti-inflammatory effects of ethanol extracts from Forsythia viridissima Lindley's fructus and Lonicera japonica Thunberg's flos were evaluated by checking the following substances of LPS-activated Raw264.7 cell: Prostaglandin E₂ (PGE₂), Nitric oxide (NO), Cyclooxygenase-2 (COX-2), inducible Nitric oxide synthase (iNOS), Interlukine-1β (IL-1β), Interlukine-6 (IL-6), Tumor necrosis factor-α (TNF-α), mitogen-activated protein kinase (MAPK), Inhibitor of kappa B-α (IκBα), Nuclear factor kappa B (NF-κB). And additionally measured reactive oxygen species (ROS) and free radicals to check the antioxidant effect of ethanol extracts from Forsythia viridissima Lindley's fructus and Lonicera japonica Thunberg's flos which affect inflammatory responses. Results: As a result of measuring anti-inflammatory efficacy, PGE2, NO, IL-1β, IL-6, TNF-α production amounts were reduced in the ethanol extracts from Forsythia viridissima Lindley's fructus and Lonicera japonica Thunberg's flos groups compared with the control group, and decreased the amount of COX-2 mRNA, iNOS mRNA gene expression. Expression of MAPK (ERK, JNK, p38) pathway was decreased. Expression of IκBα was increased and NF-κB was decreased. It is demonstrated that ethanol extracts from Forsythia viridissima Lindley's fructus and Lonicera japonica Thunberg's flos, by reducing NF-κB, regulate the expression of the inflammatory genes and reduce the inflammatory mediators. Ethanol extracts from Forsythia viridissima Lindley's fructus and Lonicera japonica Thunberg's flos also decreased ROS production and free radicals, which shown to have antioxidant efficacy and influence anti-inflammatory effects. Conclusions: These data suggest that ethanol extracts from Forsythia viridissima Lindley's fructus and Lonicera japonica Thunberg's flos can be used to treat various inflammatory diseases.

The present study was undertaken to estimate the antibacterial effect of a combination of C. rhizoma, L. Flos, and P japonica (1:1:1) extracts (CLP1000) and a combination of the herbal extract mixture and dioctahedral smectite (CLPS1000) against murine salmonellosis. At the concentration of CLP1000 and CLPS1000 0.5 mg/ml, the antibacterial effect was not showed on Salmonella typhimurium (S. typhimurium). On the other hand, the antibacterial effect against S. typhimurium was observed at the concentration of CLP1000 and CLPS1000 1.0 mg/ml. Oral administration of Smectite, CLPl000, and CLPS1000 at the dose of 10 mg/ml showed a therapeutic effect for S. typhimurium infected BALB/c mice. The mortality of Smectite, CLP1000 and CLPS1000-treated mice was 90%, 90%, and 70% at 12 days, respectively, while that of untreated mice was 100% at 9 days after a lethal dose of S. typhimurium infection. The results of our study strongly indicate that CLPS1000 has potential as an effective of salmonellosis.

Objectives : Lonicerae japonicae Flos(LJF) has been reported to exhibit anti-oxidant, anti-inflammatory, anti-viral, anti-rheumatoid properties. However, it is still largely unknown whether LJF inhibits the ultraviolet(UV)B-induced oxidative damage in human HaCaT keratinocytes. Therefore in this paper, we investigated the anti-oxidative capacity and protective effect of LJF against UVB-induced oxidative demage in human HaCaT keratinocytes. Methods : To evaluate the anti-oxidative activity of LJF extracts, we measured total phenolic contents, total flavonoid contents, antioxidant capacity, and superoxide scavenging activity. To give an oxidative stress to HaCaT cells, UVB was irradiated with $200mJ/cm^2$ to HaCaT cells. To detect the protective effect of LJF against UVB, we measured cell viability, DNA fragmentation and reactive oxygen species (ROS) production. In addition, we performed high-performance liquid chromatography (HPLC) analysis to find a major component of LJF. Results : LJF contained phenolic and flavonoid contents, and showed the anti-oxidant and superoxide scavenging activity. The UVB-induced oxidative conditions led to the cell death, DNA fragmentation and reactive oxygen species (ROS) production. However, pretreatment with LJF reduced oxidative conditions, including inhibition of cell death, DNA fragmentation and ROS production. In addition, we found out chlorogenic acid as major component of LJF. Conclusions : These results could suggest that LJF contained anti-oxidative contents and exhibited protective effects against UVB on human HaCaT keratinocytes. And the effective compound of LJF which could show protective activities against UVB is chlorogenic acid. Thus, LJF and chlorogenic acid would be useful for the development of drug or cosmetics treating skin troubles.

Objective : The object of this study was to observe the effects of Lonicerae Flos (LF) aqueous extracts on lipopolysaccharide (LPS)-induced rat acute lung injury. Method : Five different dosages of LF extracts were orally administered once a day for 28 days before LPS treatments, and then all rats were sacrificed after 5 hour-treatment of LPS. Eight groups of 16 rats each were used in the present study. The following parameters caused by LPS treatment were observed ; body weights, lung weights, pulmonary transcapillary albumin transit, arterial gas parameters (pH, $PaO_2$ and $PaCO_2$) bronchoalveolar lavage fluid (BALF) protein lactate dehydrogenase (LDH), and proinflammatory cytokines tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$) contents, total cell numbers, neutrophil and alveolar macrophage ratios, lung malondialdehyde (MDA), myeloperoxidase (MPO), proinflammatory cytokines TNF-${\alpha}$ and IL-$1{\beta}$ contents. In addition, the histopathologic changes were observed in the lung in terms of luminal surface of alveolus, thickness of alveolar septum, number of polymorphonuclear neutrophils. Result : As results of LPS-injection, dramatical increases in lung weights, pulmonary transcapillary albumin transit increases, increases in $PaCO_2$, decreases in pH of arterial blood and $PaO_2$, increases of BALF protein, LDH, TNF-${\alpha}$ and IL-$1{\beta}$ contents, total cells, neutrophil and alveolar macrophage ratios, TNF-${\alpha}$ and IL-$1{\beta}$ contents increases were detected with decreases in LSA and increases of alveolar septum and PMNs numbers, respectively as compared with intact control. These are means that acute lung injuries (resembling acute respiratory distress syndrome) are induced by treatment of LPS mediated by inflammatory responses, oxidative stress and related lipid peroxidation in the present study. However, these LPS-induced acute lung injuries were inhibited by 28 days continuous pretreatment of 250 and 500mg/kg of LF extracts. Because of lower three dosages of LF treated groups, 31.25 and 62.5 and 125mg/kg did not showed any favorable effects as compared with LPS control, the effective dosages of LF in LPS-induced acute lung injuries in the present study, is considered as about 125mg/kg. The effects of 250mg/kg of LF extracts showed almost similar effects with ${\alpha}$-lipoic acid 60mg/kg in preventing LPS-induced acute lung injuries. Conclusion : It seems that LF play a role in protecting the acute respiratory distress syndrome caused by LPS.

Objectives : Osteoporosis is a systemic skeletal disease that decreases bone density and increases the risk of fractures. Bisphosphonates and SERMs are mainly used to treat osteoporosis, but, long-term use increases the risk of side effects such as jaw bone necrosis and breast cancer. Therefore, it is necessary to develop a therapeutic agent for a natural product with few side effects. Water extract of Lonicerae Japonicae Flos (wLF) was mainly found to have anti-cancer and anti-inflammatory effects. However, the effect of wLF on osteoporosis has not been elucidated. Therefore, this experiment investigated the effect of wLF on osteoclasts, osteoblasts and osteoporosis models. Methods : In order to study the effect of wLF on osteoporosis, the OVX-induced rat model was used for in vivo study. After 8 weeks, we measured body weight, uterine weight, liver weight, femur weight, bone density, trabecular area and tibia ash weight. To determine the effect of wLF on osteoclast differentiation, we measured the number of TRAP-positive cells and TRAP activity. To examine the effect of wLF on the expression of osteoblast-related genes, we measured the mRNA expression of alkaline phosphatase (ALP, Alpl) and osteocalcin (OCN, Bglap2). Results : In vivo experiment, wLF inhibited the reduction of femur weight, trabecular area, bone density and tibia ash weight. In vitro experiment, wLF had no significant effect on osteoclast differentiation. However, wLF increased the mRNA expression of Alpl and Bglap2 in MC3T3-E1 cell. Conclusions : This result suggested that wLF may be used for the treatment and prevention of postmenopausal osteoporosis.
