Objectives : Allergic disease has been well known as an IgE-dependent immunologic response. Recently, interest about the late inflammatory reaction has grown up as well as early allergic reaction characterized by IgE and mast cell. The purpose of this study was to find the anti-inflammatory effect of Gamiyunjo-tang(GMYJT) in allergic reaction. Methods : The experiment was performed using Raw 264.7 cells pretreated with GMYJT extracts. In this study, we observed the toxicity of cells by MTT analysis and measured the production of LPS-induced NO, $PGE_2$, IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ at a concentration of 50, 100, 200 and $400{\mu}g/ml$. Results : No toxicity of GMYJT (50, 100, 200, $400{\mu}g/ml$) on RAW 264.7 cells was found after 24 hours incubation. LPS-induced NO production was reduced after treatment with GMYJT (100, 200, $400{\mu}g/ml$)(P<0.05). $PGE_2$ was reduced after treatment with GMYJT (100, 200, $400{\mu}g/ml$)(P<0.05). IL-$1{\beta}$ did not decrease at any dose. IL-6 decreased at 200, $400{\mu}g/ml$(P<0.05). TNF-${\alpha}$ production decreased only at $400{\mu}g/ml$(P<0.05). Conclusions : These data suggest that GMYJT has anti-inflammatory effects in late allergic reaction.

Objectives: The purpose of this study is to investigate and analyze Korean domestic patents on aconiti ciliare radix and to identify the trend of aconitum tuber technology. Methods: To analyze the patent, a combinations of words such as "aconitum" or "korean aconite root" were used in search engine Kipris(www.kirpis.or.kr). The patents of aconiti ciliare radix were analyzed in three ways: year trend analysis, internatonal patent classification (IPC) code analysis related to content classification, and patent registration status analysis. Results: Among the patents found in the search results, 17 patents with significant contents were analyzed. Results showed that, first, patents were steadily registered until 2018, but recently there has been no new patent registration. Second, there were many patents related to efficacy verification and decoction method, and the number of IPC codes related to them was also high. Third, there are five patents maintaining the registration status, and they are patents related to the aconiti ciliare radix extraction method, toxicity removal, and combination method. Conclusions: In this study, the domestic patents of aconiti ciliare radix were analyzed. The analysis results of this study are expected to be exploited as basic data for the development of Korean medicine analgesics with fewer side effects by suppressing tuber toxicity and the creation of new medical technologies.

With tablets and powder, decoction has been a widely-used method of medicine formula. However, for these formulas have unique bitter tastes and flavors of herbal component materials as it is, the compliance of herbal medicine is severly decreased especially for female and younger patients. Consequently, expected treatment effects can't be acquired completely. If loathsome tastes and flavors of decoction were effectively reduced while pharmacological activity were kept intact, the compliance could be promoted Chong-Myung-Tang has been widely prescribed for student patients with memory This study shows that Chong-Myung-Tang+chocolate have no difference from Chong-Myung-Tang in terms of pharmacological activity. Sensory difference with net chocolate was also surved. In order to observe the difference of Chong-Myung-Tang+chocolate and Chong-Myung-Tang, memory impairment was induced by intraventricular injection of $A{\beta}_{25-35}$ peptides on mice and Chong-Myung-Tang and Chong-Myung-Tang+chocolate were administered orally for 14 days. In water maze task, improvement of learning ability during acquisition period and significant increase of memory score during retention period resulted from the treatment of Chong-Myung-Tang and Chong-Myung-Tang+chocolate with respect to the $A{\beta}-injected$ control animals. Furthermore, the $A{\beta}_{25-35}$ toxicity on the hippocampus was assessed with immunohistochemistry (Bax, TUNEL), and differences in antioxidant activity was observed through TBARS and DPPH test. We employed sensory tests using chocolate flavor, herb flavor, and bitter taste & hardness as standards to show sensory differences with net chocolate. In this study, it is demonstrated that Chong-Myung-Tang+chocolate do not disturb the pharmacological activity of Chong-Myung-Tang, and have no sensory difference with net chocolate. Chong-Myung-Tang+chocolate can be used to enhance the compliance remarkably and thought of as an effective, functional formula to maximize expected treatment.

This study investigated the anti-inflammatory activities and cell viability of Amelanchier asiatica (A. asiatica) 70% ethanol extracts against RAW 264.7 cells induced by lipopolysaccharide (LPS). Cell toxicity test on macrophage cells (RAW 264.7) was performed by 3-[4,5-dimethyl-thiazol-2-yl]-2, 5-diphenyl-tetrazoliumbromide (MTT) assay and results showed 96% cell viability at $1,000{\mu}g/mL$ concentration. Anti-inflammatory activity was examined via the inhibitory tests on the production of LPS induced NO in RAW 264.7 cells by Griess assay. The result showed that the extract inhibited NO production in concentration dependent manner. The iNOS and COX-2 protein expression inhibitory effects were confirmed by western blot and by reverse transcription-polymerase chain reaction (RT-PCR). From the former they were decreased by 84.3%, 56.2% at $500{\mu}g/mL$ concentration, respectively, and from the latter decreased by 89.8%, 84.9% at $500{\mu}g/mL$, respectively. In conclusion, this study showed the anti-inflammatory effects of A. asiatica extracts. Thus, this could be applied to an anti-inflammatory agent.

Background: In recent years, adjuvants have received increasing attention owing to the development of purified subunit and synthetic vaccines which are poor immunogens and require additional adjuvants to evoke an immune response. Therefore, immunologic adjuvants have been developed and tested. Plant polysaccharides have been recognized as effective biological response modifiers with low toxicity. Methods and Results: In this study, the polysaccharide from the aboveground part of Astragalus membranaceus Bunge containing immunomodulating arabino-3,6-galactan was evaluated for its hemolytic activity and adjuvant potential in the specific cellular and humoral immune responses to ovalbumin. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge was co-immunized with the purified Vi capsular polysaccharide of Salmonella typhi vaccine in mice. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge did not induce any hemolytic activity or side effects at doses up to $500{\mu}g/m{\ell}$. The concanavalin A-, lipopolysaccharide-, and ovalbumin-induced splenocyte proliferation and serum ovalbumin-specific IgG, IgG1 and IgG2b antibody titers in immunized mice were significantly enhanced by AMA. Pharmacological data revealed that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge increased antigen-specific antibody levels in immunized mice. The polysaccharide from the aboveground part of Astragalus membranaceus Bunge-adjuvanted purified Vi capsular polysaccharide of Salmonella typhi vaccine improved the proliferation of splenocytes and macrophages as well as stimulated cytokine production. Conclusions: These results suggest that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge-adjuvanted vaccines enhanced humoral and cellular immunity and that the polysaccharide from the aboveground part of Astragalus membranaceus Bunge is a safe and efficacious adjuvant candidate suitable for use in prophylactic and therapeutic vaccines.

We studied the effects of the extract of aerial parts of hydroponically cultured ginseng (HGE) on alcohol-induced liver damage (AILD) in mice. AILD was induced by the oral administration of ethanol (EtOH) (25%; 5 g/kg body weight) for seven days in the study as well as EtOH-only groups. However, HGE (4 and 12 mg/kg) was orally administered (once daily for ten consecutive days) only to the study group, three days prior to the EtOH treatment. The HGE-treated group showed significantly lower levels of alanine aminotransferase and aspartate aminotransferase than the EtOH-only group. In addition, HGE administration decreased the level of serum lactate dehydrogenase, a known marker of liver damage. The effect of HGE on AILD was found to be dose dependent, and the consecutive administration of HGE showed no side effects in mice. Our study indicates that HGE treatment can potentially reduce oxidative stress and toxicity in the liver of alcohol-treated mice and that HGE can be a useful therapeutic agent for alcohol-induced hepatotoxicity. Additionally, a simple and efficient high-performance liquid chromatography-ultraviolet detection method was developed for determining the contents of four major ginsenosides in HGE. The aerial parts of hydroponically cultured ginseng were extracted using 70% fermented ethanol, and the contents of ginsenosides F5, F3, F1, and F2 in HGE were found to be 2.5, 4.4, 1.4, and 23.3 mg/g, respectively.

Objectives : Butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) were well known as anti-oxidant, but they were limited to use because of toxicity. So, many studies are being done to develope natural anti-oxidant. Total phenolic and flavonoid contents along with total antioxidant capacity of the ethanolic extract of Plantaginis Herba (PH) were evaluated to explore the reliable and potential sources of novel natural antioxidants. Methods : Total polyphenol contents and total flavonoid contents in PH ethanol extract were determined by colorimetric method. And DPPH(1.1-diphenyl-2-picrylhydrazyl), ABTS(2'-azino-bis (3-ethylbenzothiazoline-6-Surfonicacid)) free radical scavenging capacity and reducing power inhibition activities of PH ethanol extract were measured at 100, 500, 1000, $5000{\mu}g/m{\ell}$ concentrations by spectrometric assay. Results : The total polyphenol contents and total flavonoid contents of the extract were 161.99 mg/g, 144.05 mg/g, respectively. Also, DPPH, ABTS free radical scavenging capacity and reducing power of PH ethanol extract in treated concentrations (100, 500, 1000, $5000{\mu}g/m{\ell}$) increased dose dependently. In particular, DPPH free radical scavenging capacity of PH ethanol extract from $500{\mu}g/m{\ell}$ was significantly increased compared to positive control (BHA). ABTS free radical scavenging capacity of PH ethanol extract from $1000{\mu}g/m{\ell}$ was significantly higher than BHA. Also, reducing power showed that PH ethanol extract from $500{\mu}g/m{\ell}$ was significantly increased compared to BHA. Conclusions : These results suggest that PH ethanol extract has effects to scavenge free radicals, thus PH has potential and applicable benefits for development of materials and products to have anti-oxidation functions.

The purpose of this study is to verify the anti-inflammatory effectiveness of Cheongyeoungkeumyeum(CYK) including seven herbal medicines of that major effectiveness is to clear heat, to relieve fire toxicity and to clear damp-heat. To evaluate anti-inflammatory effectiveness of CYK, we measured the production of reactive oxygen species(ROS), nitric oxide(NO) cyclooxygenase-2(COX-2) and in TNF-${\alpha}$ LPS-activated Raw 264.7 cells. Cell viability was determined by MTT assay. The concentrations of ROS and relative level of NO were measured with DPPH assay and Griess reagent, respectively. COX-2 and TNF-${\alpha}$ were detected by enzyme immuno assay(EIA) and enzyme-linked immunosorbent assay(ELISA). As a result, we found that CYK suppressed LPS-induced ROS and NO production in a dose-dependent manner. Also CYK significantly inhibited LPS-induced COX-2 activity and the release of TNF-${\alpha}$. These results indicate that the CYK may have an anti-inflammatory agent for the treatment of various inflammatory disease.

Objective : Five most generally adopting basic oriental prescriptions (yookmijihwangtang, ojeoksan, sipjeondaebotang, samultang, bojoongikgitang) samples were collected from 10 oriental hospitals nationwide and the transferring ratio to aqueous phase (TRAP) were calculated. Method : The samples are grounded evenly and the decocted at $120^{\circ}C$ for 12 min on hot plate and then filtered. The concentrations of As, Cd, Co, Cr and Pb in before and after decoction were measure by ICP/MS and the TRAPs were calculated. Results : The concentrations of As, Cr and Pb in the ground samples before decoction were all below criteria level, and TRAP values were also very low (<10%). For Cd, although some ground samples before decoction showed relatively high concentration level compare to the criteria level, because of their low TRAP (~3%), the actual concentrations in the decoction were quite low compare the criteria level. The Co's concentrations in the ground samples before decoction were all relatively low level. However, the TRAP of Co was astonishingly high value of around 40% average. Conclusion : The toxic heavy metal concentrations in the decoction were very low compare to the criteria level. The TRAPs are less than <10% except Co. The toxic heavy metals in the prescriptions are mainly remained in the residue and the only very small fraction may transferred to the decoctions. Therefore the toxicity of the oriental herbal medicine about the toxic heavy metal may be overstressed. The Co's TRAP turned out to be quite high value (40% average). Since the criteria level wes not established yet, the safety of decoctions according to Co was not fully confirmed.

The neuroprotective effects of herbal ethanol extracts from Gynostemma pentaphyllum (GP-EX) in 6-hydroxydopamine (6-OHDA)-lesioned rat model of Parkinson's disease treated with L-DOPA were investigated. Rats were prepared for the Parkinson's disease model by 6-OHDA-lesioning for 14 days. The rats were then treated with L-DOPA (10 and 20 mg/kg) with or without the oral administration of GP-EX (30 mg/kg, daily) for 28 days. L-DOPA (20 mg/kg) treatment for 28 days enhanced dopaminergic neuronal cell death in 6-OHDA-lesioned rat groups, but L-DOPA (10 mg/kg) did not. However, the oral administration of GP-EX (30 mg/kg) for 28 days ameliorated the enhanced neurotoxic effects induced by chronic L-DOPA treatment in 6-OHDA-lesioned rat groups by increasing tyrosine hydroxylase (TH)-immunohistochemical staining and the number of TH-immunopositive cells surviving in the substantia nigra. In addition, GP-EX administration (30 mg/kg) for 28 days recovered the levels of dopamine and norepinephrine of the striatum in 6-OHDA-lesioned rat groups, which were markedly reduced by L-DOPA treatment (20 mg/kg). GP-EX (30 mg/kg) did not produce any signs of toxicity, such as weight loss, diarrhea, or vomiting in rats during the 28-day treatment period. These results suggest that GP-EX has protective functions against chronic L-DOPA-induced neurotoxic reactions in dopaminergic neurons in the 6-OHDA-lesioned rat model of Parkinson's disease. Therefore, GP-EX may be beneficial in the prevention of adverse symptoms in parkisonian patients.
