We evaluated the benign prostatic hyperplasia (BPH) with Yacon pill, the preparation composed of Smallanthus sonchifolius, Torilis japonica and Acorus gramineus. A total of 45 rats were divided into five groups. One group was used as a control and the other groups received subcutaneous injections of testosterone for 4 weeks to induce BPH. Yacon pill extract (200 or 400 mg/kg) was administered daily for 4 weeks to two groups by oral gavage concurrently with testosterone. The rats euthanized, the prostate and body weights were recorded, and tissues were subjected to hormone assay. In addition, we investigated proliferating cell nuclear antigen (PCNA) expression in the prostate using immunoblotting. Rats with BPH showed significantly increased prostate weights, increased dihydrotestosterone (DHT) levels in the serum and increased PCNA expression in the prostate; however, Yacon pill extracts treated rats showed significant reduction of prostate weights, DHT levels and PCNA expression compared with the BPH group. Conclusively, Yacon pill showed the possibility as ameliorable agents of BPH symptoms.

The purpose of this study was to investigate the effects of natural herb mixture containing Laminaria japonica Areschoung (LAM) on fine dust-induced bronchitis in mice. Laminaria japonica Areschoung is main content of LAM, which is including fucoidan. Fucoidan extracted from phaophyta is known to prevent bronchitis and to defend against bacteria and virus infection. In this study, we experienced the effect of LAM on bronchitis and investigated gene expressions (e.g ; IL-8, COX-2, MCP-1) and bio-markers (e.g ; IL-8, PGE2, MUC5AC) associated with bronchitis by using A549 cells. Also, we investigated whether LAM can suppress the bronchitis in fine dust-induced animal models. We injected fine dust (50 ㎕) twice as INT (Intra-Nasal-Trachea) method. Then LAM (200 mg/kg and 400 mg/kg) were oral administered for 14 days. We analyzed the number of immune cells, immunoglobulin E, bio-markers level associated with bronchitis. LAM significantly decreased bio-marker (IL-1β, IL-6, IL-8, TNF-α, Histamine, PGE2), immune cells (white blood cell, neutrophil, lymphocyte, monocyte), and immunoglobulin E, that are increased by fine dust. Taken together, this study suggest that LAM can be used as effective herbal extract for bronchitis.

The dried roots of Danshen (Salvia miltiorrhiza) and Sanchi (Panax notoginseng) have been widely used in traditional Chinese medicine for promoting blood circulation as well as various other bodily functions. Here we investigated the effects of a mixture of aqueous extracts of Danshen and Sanchi, named PASEL, on blood pressure and vascular contractility in rats. Orally administered PASEL (62.5 mg/kg and 250 mg/kg, for 5 weeks) lowered the blood pressure of spontaneous hypertensive rats (SHR) but this was not observed in normal Wistar-Kyoto rats (WKR). We then investigated the effects of PASEL on the arterial contraction of the small branches of cerebral arteries (CAs) and large conduit femoral arteries (FAs) in rats. PASEL did not affect high-K (KCI 60 mM)- or phenyleprine (PhE)-induced contracture of FAs. The myogenic response, a reactive arterial constriction in response to increased luminal pressure, of small CA was dose-dependently suppressed by PASEL in SHR as well as control rats. Interestingly, the KCI-induced contraction of small CAs was slowly reversed by PASEL, and this effect was more prominent in SHR than control WKR. PASEL did not inhibit angiotensin-converting enzyme (ACE) activity. These results demonstrated that the antihypertensive effect of PASEL might be primarily mediated by altering the arterial MR, not by direct inhibition of L-type $Ca^{2+}$ channels or by ACE inhibition.

Korean red ginseng (Panax ginseng Meyer) is a well-known traditional medicine, with numerous biological functions in the body. Portulaca oleracea (P. ole) belongs to the Portulacaceae family and has bioactive potential as a traditional medicine. This study aimed to determine the anti-inflammatory effects of Korean red ginseng extract (RGE) and P. ole extract on lipopolysaccharide (LPS)-treated RAW 264.7 cells. The combination of RGE (50 ㎍/mL) and P. ole (6.25 ㎍/mL) extracts significantly suppressed LPS-induced nitric oxide synthesis. The expression of proinflammatory mediators, including inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), and proinflammatory cytokines, including interleukin-1β, interleukin-6, and tumor necrosis factor-α, were markedly decreased by the combined treatment with RGE (50 ㎍/mL) and P. ole (6.25 ㎍/mL). Moreover, iNOS and COX-2 protein expression levels were also significantly reduced in the combined treatment compared to the LPS-stimulated group. In addition, the nuclear translocation of phosphorylated nuclear factor kappa-B was suppressed by the treatment with RGE and P. ole. Moreover, the mitogen-activated protein kinase pathway was also partially inhibited by the combination treatment with RGE and P. ole. Our results demonstrate that the treatment mixture with RGE and P. ole could be used as functional food and therapeutic herbal medicine in various inflammatory diseases.

A high performance liquid chromatographic (HPLC) method for the simultaneous determination of hesperidin and glycyrrhizin was established for the quality control of traditional herbal medicinal preparation, Pyungwi-san (PWS). Separation and quantification were successfully achieved with a Waters XTerra RP18 column ($5{\mu}m$, 4.6 mm I.D. ${\times}$ 150 mm) by gradient elution of a mixture of acetonitrile and water containing 0.03% phosphoric acid (pH 2.03) at a flow rate of 1.0 ml/min. The diode-array UV/vis detector (DAD) was used for the detection and the wavelength for quantification was set at 230 nm. The presence of hesperidin and glycyrrhizin in this extract was ascertained by retention time, spiking with each authentic standard and UV spectrum. All four compounds showed good linearity $(r^2>0.995)$ in a relatively wide concentration ranges. The R.S.D. for intra-day and inter-day precision was less than 7.0% and the limits of detection (LOD) were less than 60 ng. The mean recovery of each compound was 99.0-105.6% with R.S.D. values less than 4.0%. This method was successfully applied to the determination of contents of hesperidin and glycyrrhizin in three commercial products of PWS. These results suggest that the developed HPLC method is simple, effective and could be readily utilized as a quality control method for commercial PWS products.

Schisandra chinensis (SC) and Lycium chinense (LC) were widely distributed in Asia and the fruit has been used traditionally for medicinal herbs. The processing method was solid-state fermentation using Aspergillus oryzae for 48 h after stir-frying treatment at $220^{\circ}C$ for 12 min. In this study, in vitro the anti-inflammatory effect and in vivo hangover reduction were compared to unprocessed SC and LC water extract. Anti-inflammatory effects have been evaluated in pro-inflammatory mediators which were secreted by lipopolysaccharide (LPS)-induced RAW 264.7 macrophages. Nitric oxide (NO) was determined using Griess reaction. Proinflammatory cytokines such as tumor necrosis factor $(TNF)-{\alpha}$ and interleukin $(IL)-1{\beta}$ were measured by enzyme-linked immunosorbent assays (ELISA). Alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities were compared to processed SC or LC and mixtures thereof (1:1). In vivo study was compared to hangover relief in alcohol-fed mice. After administering a mixture of SC and LC (300 mg/kg) water extract (1:1), mice were fed 3 g/kg of ethanol. Serum was collected at 1, 3, and 5 h intervals to analyze ethanol and acetaldehyde levels using a colorimetric assay kit. The processed SC and LC water extracts compared to raw materials significantly inhibited LPS-induced NO and inflammatory cytokine production in RAW 264.7 cells. The results of the hangover mouse model are also consistent with anti-inflammatory effects. These results suggest that processed SC and LC extracts may be functional materials for the treatment of inflammation and hangover.

Host plants of the Henosepilachna vigintioctomaculata are known as Solanaceae plants such as potato, tomato, eggplant and Lycium chinense. Henosepilachna vigintioctomaculata (Motschulsky) cause continuous damage from early June to mid-August in leaves of L. chinense under environmental-friendly management in Cheongyang, Chungnam. The developmental period of egg and larva of H. vigintioctomaculata were investigated. H. vigintioctomaculata were reared on L. chinense at several temperatures, for example, 15, 20, 25 and $30^{\circ}C$ in the laboratory. In addition, the control effect of 5 eco-friendly agricultural materials were examined. As results, hatching rate is the highest to 91% at $25^{\circ}C$. Egg periods were 10.8, 7.7, 5.1 and 3.7 days at each tested temperature, respectively. And the total developmental periods from egg to adult were 42.7, 26.3, 18.4 and 19.4 days at each tested temperature, respectively. Otherwise, their eclosion rates from pupa to adult were showed 58%, 77%, 85%, 65% at each tested temperature, respectively. As a result of the control effect, both adults and larvae of H. vigintioctomaculata were shown a high mortality to mixture with extract of Sophora flavescens, Chenopodium ambrosioides and Melia azedarach. Additional, larvae is shown high mortality to extract of Azadirachta indica and Cymbopogon nardus. Thus H. vigintioctomaculata might be controled by using plant extract of eco-friendly agricultural materials in due season.

During a screening program to search the anticolitic herbal medicines, 80% ethanol extract of the rhizome of Anemarrhena asphodeloides (AA) was found to potently inhibit the expression of proinflammatory cytokines TNF-${\alpha}$ and IL-1${\beta}$, as well as the activation of NF-${\kappa}B$ in LPS-stimulated colonic macrophages, followed by that of the rhizome of C. chinensis (CC). AA also potently inhibited TNBS-induced colitic markers, shortening of the colon and increase of macroscopic score, myeloperoxidase activity, TNF-${\alpha}$, IL-1${\beta}$, and IL-6, in mice. The synergistic effect of CC against the anticolitic effect of AA was investigated. CC synergistically inhibited the anticolitic effect of AA. AC-mix (AA+CC, 1:1) potently inhibited them. AC-mix also inhibited the activation of NF-${\kappa}B$, as well as the expression of TNF-${\alpha}$, IL-1${\beta}$, IL-6, iNOS and COX-2. The effects of AC-mix against oxazolone-induced colitis were investigated in mice. AC-mix also potently inhibited oxazolone-induced inflammatory markers, colon shortening, macroscopic score, myeloperoxidase activity, NF-${\kappa}B$ activation and proinflammatory cytokines. Overall, the anti-colitic effect of AC-mix was superior to that of mesalazine. Based on these findings, AC-mix may improve colitis by inhibiting NF-${\kappa}B$ activation.

Rapidly progressive interstitial renal fibrosis has recently been reported in young women who have been on a slimming regimen including chinese herbs. Aristolochic acid, suspected as the causal factor of this renal disease, is a well known carcinogen. It has been known that Madouling (Aristolochiae fructus) contains aristolochic acid. The objective of this study was to investigate the effects of Madouling, Madouling-tang, which are the extract mixture from 10 different chinese herbs including Madouling, and aristolochic acid on reproductive and developmental toxicity. Female rats were administered orally with the extracts of Madouling, madouling-tang, and aristolochic acid from 14 days before mating to day 17 of gestation. Madouling (8mg/kg) decreased fertility in the 8mg/kg group, but Madouling-tang and aristolochic acids did not. Significant decrease of mean fetal body weights were observed in the 16mg/kg group of aristolochic acids. External, visceral and skeletal malformation of fetuses were not observed with treatment. Histopathological examination showed the discrete damage of kidney in the 8mg/kg group of Madouling and 16mg/kg groups of aristolochic acid. In whole embryo culture, Madouling and Madouling-tang caused the retardation of growth and development of embryo in the dose of 1 $\mu$g/ml and 0.02 $\mu\textrm{g}$/kg, respectively while aristolochic acids showed the similar effect in the dose of 300 $\mu\textrm{g}$/kg. These results indicate that Madouling, up to 0.05mg/kg (prescription dose to human) has no adverse effects on the fertility, reproduction and development of Sprague-Dawley rats.
