Epimedii Herba is an important traditional herb medicine widely used as a tonic. However, the mechanism of action of this drug on the immune system is not well studied. This study was performed to elucidate the effects of the aqueous extract of Epimedii Herba on the production of antibodies in mice. Antibodies in serum were detected in male ICR mice treated with the aqueous extract of Eplmedii Herba (AEEH) at a dosage of 40, 120, and 360mg/kg orally for 2 weeks. Effects of oral administration of AEEH on antibody forming responses were measured by enzyme linked immunosorbent assay (ELISA) of immunoglobulin (Ig) levels in serum. The results were as follows; 1. Epimedii Herba slightly decreased body weight gain. 2. Epimedii Herba significantly increased the relative spleen weight. 3. Epimedii Herba significantly increased total serum IgG levels. 4. Epimedii Herba significantly enhanced total serum IgG1 levels. 5. Epimedii Herba significantly increased total serum IgG2a levels. 6. Epimedii Herba markedly increased total serum IgM levels. These findings demonstrate that Epimedii Herba significantly enhances the production of antibodies at therapeutic concentrations, and suggest that administration of Epimedii Herba may prevent the host from immunologic diseases.

The pistil of nelumbo nucifera (PNN) is used in the treatment of nocturnal pollution, hematemesis, epistaxis, metrorrhagia and diarrhoea in traditional medicine. The present study was examined to evaluate the effects of PNN on the production of pro-inflammatory mediators in vitro. After the treatment of PNN, cell viability was measured by MTT assay, nitric oxide (NO) production was monitored by measuring the nitrite content in culture medium. The protein bands were determined by immunoblot analysis and levels of cytokines were analyzed by sandwich immunoassays. In the MTT assay, the doses of PNN extract (0.03, 0.10 mg/ml) had no significant cytotoxicity. The increases of NO production and inducible nitric oxide synthase expression were detected in lipopolysaccharide(LPS)-activated Raw 264.7 cells compared with control, in contrast, these increases were significantly attenuated by pre-treatment with PNN. In cytokine assay, the massive pro-inflammatory cytokines such as tumour necrosis factor-$\alpha$, interleukin (IL)-$1{\beta}$ and IL-6 were induced in LPS-activated Raw 264.7 cells, but pre-treatment of Raw 264.7 cells with PNN caused inhibition (TNF-$\alpha$=14.17%, IL-$1{\beta}$=107.43%, IL-6=46.27%) the production of cytokines by LPS. In addition, PNN reduced prostaglandin E2 productions in a dose-dependent manner (0.03mg/ml=37.52%, 0.10 mg/ml=83.77%) as a consequence of the inhibition of cyclooxygenase-2 expression. Taken together, our data indicates that PNN can regulate the inflammatory response in macrophage cells activated by Gram-negative infection.

Objectives : Polygoni Multiflori Ramulus has been widely used as a traditional medicinal herb for the treatment of insomnia, limb pain and itch. The extract of Polygoni Multiflori Ramulus (PMRE) is known to have a modulatory effect of many inflammatory responses. This study was performed to investigate the hepatoprotective effect of PMRE against arachidonic acid (AA) + iron-induced oxidative stress on HepG2 cell and carbon tetrachloride ($CCl_4$)-induced liver injury on mice. Methods : The effects of PMRE on cell viability was assessed by MTT assay. And flow cytometric analysis was performed to estimate the effects on mitochondrial function. To investigate its underlying mechanism, apoptosis-related proteins were analysed by using immunoblot analysis. In addition, ICR mouse were administrated (po) with the PMRE (30, 100 mg/kg) for 3 days and then, injected (ip) with $CCl_4$ (0.5 ml/kg body weight) to induce acute liver damage. The level of pro-caspase-3 was measured. Results : Treatment of PMRE increased relative cell viability, prevented a cleavage of poly (ADP ribose) polymerase and pro-caspase-3, and also reduced mitochondrial membrane permeability against AA + iron-induced oxidative stress. In addition, PMRE treatment decreased liver injury induced by $CCl_4$, as evidenced by increases in pro-caspase-3 level. Conclusions : These results demonstrate that PMRE has an ability to anti-oxidant and hepatoprotective effect against AA + iron-induced oxidative stress and $CCl_4$-induced liver injury.

Petiolus Nelumbinis, branches of lotus leaf or lotus flower is a traditional oriental herbal medicine widely used for treating a superheat or disorder of qi flow. Although there are many clinical results and literature study, it has been rarely conducted to evaluate the immuno-biological activity. The present study was conducted to examine the anti-inflammatory effects of PNM (Petiolus Nelumbinis MeOH extract) in vitro. To determine cytotoxic concentration of PNM, the cells were treated with PNM for 24 h after LPS addition, and the cell viability was tested by MTT assay. Both of dosages (30 and 100 ${\mu}g/ml$) of PNM had no cytotoxicity. In these concentrations, PNM significantly reduced the elevated levels of NO and $PGE_2$ by LPS. These inhibitory effects of PNM were due to the reduced expressions of iNOS and COX-2 protein. TNF-$\alpha$, IL-1$\beta$ and IL-6 are frequently encountered pro-inflammatory cytokines, and LPS plays a key role in inducing to the massive production of these cytokines. Thus, we next determined the levels of these cytokines. Although PNM had no significant inhibitory effect on the production of TNF-$\alpha$, the elevated levels of IL-1$\beta$ and IL-6 by LPS were dose-dependently reduced in PNM-treated groups. These results demonstrate that PNM has anti-inflammatory effects by inhibiting the production of proinflammatory cytokines, NO and $PGE_2$ in LPS-activated macrophage. Moreover, the reduction of NO and $PGE_2$ levels was due to the inhibition of iNOS and COX-2 protein expression by PNM.
