  • Objectives : Berberine, a main alkaloid component of Coptidis rhizoma, has an antimicrobial and anti-tumor activities and antiinflammatory effect. In the present study, we investigated effect of berberine on the production of inflammatory mediators such as nitric oxide(NO), prostaglandin E2(PGE2), TNF-${\alpha}$ and IL-1${\beta}$ in LPS-stimulated BV2 microglial cells, Methods : BV2 cells were pre-treated with berberine and then stimulated with LPS. The cytotoxicity of berberine was determined by MTT assay. The NO production was measured by Griess assay. The mRNA expression and protein levels of inducible nirtic oxide synthase(iNOS) were determined by RT-PCR and Western blot. The production of PGE2 and cytokines was measured by ELISA. Results : Berberine inhibited the production of NO, PGE2 and pro inflammatory cytokines, TNF-${\alpha}$ and IL-1${\beta}$ in a dose dependent manner in LPS-stimulated BV2 cells. In addition, berebrine greatly suppressed the mRNA expression and protein levels of iNOS and inflammatory cytokines induced by LPS stimulation. These results indicate that the post-transcriptional regulatory mechanism of iNOS and/or inflammatory cytokine gene expression by berberine is involved in its anti-inflammatory effects, respectively. Conclusion : The present study suggests that berberine can be useful as a potential anti-inflammatory agent for treatment of various neurodegenerative diseases such as Alsheimer's disease, Parkinson's disease and stroke.

  • The flavonoids are a very large and important group of polyphenolic natural products, which are united by their derivatization from the heterocycle, flavone. They are distributed in higher plants and occur widely in the fruits and vegetables that make up the human diet. They exhibit a wide range of biological properties, including antitumor, antiinflammatory, hepatoprotective, antimicrobial, insecticidal and estrogenic activities. They are also major components of many plant drugs and it is possible that they contribute to the curative properties. For the purpose of developing anticancer agent of natural origin, we have evaluated forty four kinds of naturally occurring flavonoids for the inhibitory activity upon the proliferation of cultured human tumor cells such as A549 (non small cell lung), SK-OV-3 (ovary), SK-MEL-2 (melanoma), XF498 (central nerve system) and HCT-15 (colon) in vitro.

  • Background: The purpose of this study was to investigate whether Sibseonsan (SSS) is an effective antiinflammatory, anti-wrinkling, and whitening agent. Methods: To determine whether SSS had an anti-inflammatory effect, a murine macrophage cell line was used (RAW 264.7) and production of DPPH, NO, TNF-α, and PGE2 were measured. To ascertain potential anti-wrinkle effects of SSS in these cells, collagenase and elastase production were measured. To verify whether SSS had a whitening effect, tyrosinase activity and DOPA staining were performed using a melanoma cell line (B16/F10). Results: There was no significant reduction in survival of SSS-treated RAW 264.7 cells, up to 400 ㎍/mL. Free radical scavenging (23.96 ± 1.85%) was observed in RAW 264.7 cells treated with SSS at a concentration of 400 ㎍/mL. The SSS treatment group (400 ㎍/mL) significantly inhibited NO production compared with the LPS stimulated treatment group. The SSS treatment of macrophage cells appeared to reduce production of TNF-α in a concentration dependent manner. There was a significant reduction in the concentration of PGE2 by about 25% in the SSS treatment (400 ㎍/mL) group (p = 0.05). Compared with the control, the production of collagenase and elastase in B16/F10 cells treated with SSS (400 ㎍/mL) was greater by 26.37% and 45.71%, respectively. The SSS treatment (400 ㎍/mL) group showed a significant reduction by about 17% in tyrosinase production in B16/F10 cells. The SSS treatment group showed little change in DOPA staining. Conclusion: SSS extract may be useful for the treatment and prevention of inflammatory diseases and may have anti-wrinkle and whitening effects. These results may support the use of SSS in clinical practice.

  • It has been documented that SPA0355 exerts antiinflammatory effects via the inhibition of nuclear factor-kappaB activation. In present study, we investigated the inhibitory effects of SPA0355 on periodontitis in an animal model. Periodontitis was induced by ligation of the cervix of the 1st molar in the left mandible in rats. After ligature, the rats were randomly divided into four groups and topically applied with SPA0355 (0.5, 1, and 2%) or the vehicle alone once daily for 10 days. Body weight and food intake were measured daily throughout the experimental period. At day 10 post-ligature, the infiltration of inflammatory cells and distance of the cementoenamel junction (CEJ) to the alveolar bone crest (ABC) in the distal area of ligatured tooth were estimated histopathologically. No changes in body weight or food intake were found between the control and SPA0355 groups. The degree of inflammation was decreased in all three SPA0355 application groups. A decrease CEJ-ABC distance was observed in the 0.5% and 1% SPA0355 groups. These results indicate that SPA0355 inhibits the infiltration of inflammatory cells and alveolar bone resorption and suggests its potential as a therapeutic agent for periodontitis.

  • Purpose: The purpose of this study was not only to evaluate the relative mRNA expression of interleukin-$1{\beta}$(IL-$1{\beta}$), cyclooxygenase2 (COX-2) and prostaglandin E2 (PGE2) by RT-PCR analysis but to observe pattern of edema by light microscopic and electron microscope after topical apply of hyaluronic acid in inflammation-guided mouse. Material and methods: Mice of this study were devided into 4 groups: Control group (no inflammation guided), Positive control (inflammation guided + vaselin apply), Protopic group (inflammation guided + protopic apply), Hyaluronic group (inflammation guided + hyaluronic acid apply). Results: Hyaluronic group showed less expressions of IL-$1{\beta}$, COX-2, PGE2 than those of positive control & protopic group. Hyaluronic group revealed a decreased inflammation than positive control & protopic group in Light Microscope. Hyaluronic group appeared decreased edema of ear compare to positive control & protopic group in Elecron Microscope. Conclusion: It was considered that hyaluronic acid has an antiinflammatory effect for intercepting the gene expression of cytokines related to inflammation.

  • Polygalae Radix (PR) from Polygala tenuifolia. (Polygalaceae) is traditionally used in China and Korea, since this herb has a sedative, antiinflammatory, and antibacterial agent. To extend pharmacological actions of PR in the CNS on the basis of its CNS inhibitory effect, the present study examined whether PR has the neuroprotective action against kainic acid (KA) -induced cell death in primarily cultured rat cerebellar granule neurons. PR, over a concentration range of 0.05 to $5{\mu}g/ml$ inhibited KA $(500\;{\mu}M)$-induced neuronal cell death, which was measured by a trypan blue exclusion test and a 3-[4,5-dimethylthiazol-2-y1]-2,5-diphenyl-tetrazolium bromide (MTT) assay. PR $(0.5{\mu}g/ml)$ inhibited glutamate release into medium induced by KA $(500\;{\mu}M)$, which was measured by HPLC. Pretreatment of PR $(0.5{\mu}g/ml)$ inhibited KA $(500\;{\mu}M)$-induced elevation of cytosolic calcium concentration $([Ca^{2+}]_c)$ which was measured by a fluorescent dye, Fura 2-AM, and generation of reactive oxygen species (ROS). These results suggest that PR prevents KA-induced neuronal cell damage in vitro.

  • To develop a novel transdermal delivery system of loxoprofen (LP), a potent antiinflammatory and analgesic agent, the effects of various vehicles and penetration enhancers on the skin permeation of LP from solution formulations were investigated. The permeation rate of LP through excised guinea pig skin was measured using a side-by-side permeation system at $32^{\circ}C$. The solubilities of LP in various vehicles were determined by the equilibrium solubility method, and partition coefficients $(P_c)$ were determined. The solubility of LP increased in the rank order of water & isopropyl myristate (IPM) & glyceryl dicaprylate/dicaprate & propylene glycol dicaprylate/caprate & propylene glycol laurate (PGL) & polyethylene glycol 400 & diethylene glycol monoethyl ether (DGME) & ethanol. n-Octanol-water $P_c$ value was 15.5. Among pure vehicles tested, IPM and PGL showed highest fluxes of $89.9{\pm}5.0$ and $45.4{\pm}0.3\;{\mu}g/cm^2/hr$ from saturated solutions, respectively. However, it was not possible to demonstrate any correlation between the solubility of LP and its permeation rate, indicating the change in the barrier property of the skin and/or carrier mechanisms by vehicles tested. The addition of DGME to IPM or PGL markedly increased the solubility of LP, but the permeation rate did not decrease when the concentration of DGME in the cosolvent was increased upto 40%. The addition of linoleic acid (3%) in the cosolvent slightly increased the permeation rate, but others such as lauroyl sarcosine, fatty alcohols and fatty acids tested did not show enhancing effect. In conclusion, the DGME-IPM or DGME-PGL cosolvent system proved to be a good vehicle to enhance the skin permeation of LP.

  • Objectives: The root of Lithospermum erythrorhizon Sieb. et Zucc. (Lithospermi Radix, LR) is a kind of heat clearing and blood cooling medicinal herbs. It can clear away heat and cool the blood, reduce toxins and disperse maculae. LR has long been used as efficacious therapy for inflammation, burns, frostbite and skin diseases such as eczema and psoriasis. Methods: In the present study, we investigate anti-allergic and anti-inflammatory effects of LR by using the 1-fluoro-2, 4- dinitrofluorobenzene (DNFB)-induced contact dermatitis mouse model. Results: Topical application of 10 mg/mL of LR effectively inhibited skin lesions induced by repeated paintings with DNFB. Topical application of LR also inhibited hyperplasia, edema, spongiosis and infiltrations of mononuclear cells. In addition, production levels of total immunoglobulin and IgG1 in serum were decreased by using LR in vivo. Conclusions: These data suggest that LR acts as an antiinflammatory agent, improving skin lesions in CD mice.

  • 혈관 증식 질환에서 세포주기 활성화와 진행은 중요한 치료 목적으로 사용된다. Luteolin는 glycosylated 형태로 샐러리, 후추, 들깨 잎 그리고 카밀레 차에 존재하며 항돌연변이, 항종양, 항산화 그리고 항염증을 나타낸다. 본 연구에서는 흰쥐 동맥으로부터 분리한 혈관평활근세포를 배양하여 소태아혈청으로 유도된 증식에서 luteolin 효과에 대해 조사했다. Luteolin이 5% 소태아혈청으로 유도된 흰쥐의 혈관평활근세포 증식과 DNA 합성을 5, 20 그리고 $50{\mu}M$에서 억제했다. 혈관평활근세포 증식을 각각 29.6, 50.8 그리고 83.1% 억제했고 DNA 합성은 각각 25.8, 57.6 그리고 81.0% 억제했다. 게다가, 유세포분석 결과 소태아혈청으로 유도된 혈관평활근세포의 세포주기는 luteolin에 의해 차단되었다. 이러한 결과는 세포독성에 의해서도 나타날 수 있기 때문에 WST-1 분석으로 세포독성을 확인한 결과 세포독성 없이 세포주기를 차단하는 효과임을 확인했다. 이상의 결과들은 luteolin이 혈관스텐트와 동맥경화의 치료를 위한 의미있는 항증식 물질임을 보여준다.
