  • 인도산 울금 분말을 bifidobacteria와 lactobacilli를 포함한 프로바이오틱 유산균으로 발효한 시료들의 소염활성 정도를 세포 내 염증성 인자들의 발현양을 관찰함으로써 평가하였다. 그 중 L. johnsonii IDCC 9203으로 발효한 시료의 소염 활성이 가장 뛰어났다. 이를 바탕으로 울금 분말을 포함한 본배양 배지에서 L. johnsonii IDCC 9203으로 21시간 동안 배양 후 얻은 상등액으로 발효 울금 원료를 제조하였고, 제조된 발효 울금 원료에 대한 소염활성 효능을 테스트하기 위해 LPS로 활성화된 raw 264.7 세포주에 처리하고 COX-2와 iNOS의 발현양을 확인하였다. 그 결과 발효 울금 원료 250 ${\mu}g$/mL까지 농도 의존적으로 COX-2와 iNOS의 발현을 감소시켰으며, 그 저해 활성은 동일 농도의 비발효 울금 원료보다 강하였다. NC/Nga 아토피 피부염 동물모델과 PCA 동물모델에서 발효 울금 원료의 효능 확인 결과 대조군에 비해 아토피 피부염의 초기 증상 개선효과와 급작형 과민반응에 대한 예방효과가 뛰어남을 확인하였다. 발효 울금 원료의 유효성분 함량을 분석했을 때 커큐민의 함량은 비발효 울금 원료에 비해 2.5배 증가했으며, 수용성 커큐민의 함량 역시 증가하였다. 또한 비스디메톡시커큐민이나 디메톡시커큐민의 함량도 증가되었을 뿐 아니라 전체 커큐미노이드 중에서 이들 유도체의 비중이 높아짐을 확인하였다. 모든 결과들을 종합하면, 울금 분말을 L. johnsonii IDCC 9203을 이용하여 발효함으로써 유효성분인 커큐미노이드들의 성분비가 변화하고 수용성 커큐미노이드의 증가에 의한 생체 이용율 증가로 울금의 소염 및 항알레르기 활성이 증가된다. 본 연구를 통해 L. johnsonii IDCC 9203으로 발효한 울금 원료는 급성기 피부염에 대한 예방 및 치료 목적으로 사용 가능할 것으로 예상된다.

  • In the present study we investigated the peripheral function of capsaicin and KR-25018, a newly synthesized capsaicin derivative, which was demonstrated to have a potent analgesic activity through different mechanism from morphine and nonsteroidal antiinflammatory drugs. Capsaicin (10-8~10-5 M) and KR-25018 (10-8~10-5 M) produced concentration-dependent contractions of the isolated guinea pig bronchi. There were no significant differences in the maximum response and the EC50 values (EC50: 0.137$\pm$0.025 $\mu$M and 0.097$\pm$0.031 $\mu$M for capsaicin and KR-25018, respectively, P>0.05). Phosphoramidon (10 $\mu$M) and indomethacin (10 $\mu$M) had no significant effect on contractile response to the submaximal concentration range of capsaicin and KR-25018 (3$\times$10-9~3$\times$10-7 M). The response to KR-25018, like that to capsaicin, was significantly inhibited by ruthenium red with reduction in the maximum response, which is indicative of non-competitive antagonism. A further common feature of the responses to capsaicin and KR-25018 in the guinea pig bronchi was their sensitivity to capsazepine. Capsazepine caused a rightward parallel shift in concentration-response curves obtained by capsaicin and KR-25018. the pA2 values of capsazepine were 5.90 and 5.99 against capsaicin and KR-25018 response, respectively. In conclusion, KR-25018 and capsaicin exert their contractile effects in the isolated guinea pig bronchial muscle by common mechanisms, probably via the activation of a specific receptor.

  • We investigated whether an aqueous extract of Polygala tenuifolia root (PTAE) inhibits secretion of inflammatory cytokines from primary cultures of mouse astrocytes. PTAE dose-dependently inhibited the Tumor necrosis $factor-{\alpha}$ $(TNF-{\alpha})$ secretion by astrocytes stimulated with substance P (SP) and lipopolysaccharide (LPS). Interleukin-1 (IL-1) has been shown to elevate $TNF-{\alpha}$ secretion from LPS-stimulated astrocytes while having no effect on astrocytes in the absence of LPS. We therefore also investigated whether IL-1 mediated inhibition of $TNF-{\alpha}$ secretion from primary astrocytes by PTAE. Treatment of PTAE to astrocytes stimulated with both LPS and SP decreased IL-1 secretion to the level observed with LPS alone. Moreover, incubation of astrocytes with IL-1 antibody abolished the synergistic cooperative effect of LPS and SP. Reverse transcriptase-polymerase chain reaction analysis demonstrated the significantly reduced level of the $TNF-{\alpha}$ mRNA was expressed in astrocytes treated with PTAE. These results suggest that PTAE has an antiinflammatory activity on the central nervous system curing some pathological disease states.

  • Substance P can stimulate secretion of tumor necrosis $factor-\;{\alpha}\;(TNF-\;{\alpha}\;)$ from astrocytes stimulated with lipopolysaccharide (LPS). Here I report that Chilbogeum can modulate cytokines secretion from primary cultures of rat astrocytes. Chilbogeum $(10\;{\mu}g/ml)$ significantly inhibited the $TNF-\;{\alpha}$ secretion by astrocytes stimulated with LPS and Substance P. Interleukin-1 (IL-1) has been shown to elevate $TNF-\;{\alpha}$ secretion from LPS-stimulated astrocytes while having no effect on astrocytes in the absence of LPS. Treatment of Chilbogeum $(10,\;100\;{\mu}g/ml)$ to astrocytes stimulated with both LPS and Substance P decreased IL-1 secretion significantly. The secretion of $TNF-\;{\alpha}$ by LPS and Substance P in astrocytes was progressively inhibited with increasing amount of IL-1 neutralizing antibody. Upon stimulation from various agents, these cells adopt a reactive phenotype, a morphological hallmark in Alzheimer's disease (AD) pathology, during which they themselves may produce still more inflammatory cytokines. Chilbogeum $(10,\;100\;{\mu}g/ml)$ significantly inhibited the $TNF-\;{\alpha}$ secretion by CCF-STTG1 astrocytoma cells stimulated with $A\;{\beta}$ and IL-1. These results suggest that Chilbogeum may inhibit $TNF-\;{\alpha}$ secretion by inhibiting IL-1 secretion and that Chilbogeum has an antiinflammatory activity in AD brain.

  • Astrocytes are glial cells that play a major role in the inflammation observed in Alzheimer's disease (AD). Upon stimulation from various agents, these cells adopt a reactive phenotype, a morphological hallmark in AD pathology, during which they themselves may produce still more inflammatory cytokines. Substance P (SP) can stimulate secretion of tumor necrosis $factor-\;{\alpha}$ $(TNF-\;{\alpha})$ from astrocytes stimulated with lipopolysaccharide (LPS). Here I report that Sunghyangjungkisan- ga- pogokyoung(Sgp) can modulate cytokines secretion from primary cultures of rat astrocytes. Sgp $(10\;to\;1000\;{\mu}g/ml)$ significantly inhibited the $TNF-\;{\alpha}$ secretion by astrocytes stimulated with LPS and SP. Interleukin-1 (IL-1) has been shown to elevate $TNF-\;{\alpha}$ secretion from LPS-stimulated astrocytes while having no effect on astrocytes in the absence of LPS. Treatment of Sgp $(10\;to\;1000\;{\mu}g/ml)$ to astrocytes stimulated with both LPS and SP decreased IL-1 secretion significantly. The secretion of $TNF-\;{\alpha}$ by LPS and SP in astrocytes was progressively inhibited with increasing amount of IL-1 neutralizing antibody. Neurodegenerative processes in AD are thought to be driven in part by the deposition of ${\beta}\;-amyloid\;(A\;{\beta})$, a 39- to 43-amino acid peptide product resulting from an alternative cleavage of amyloid precursor protein. Sgp $(10\;to\;1000\;{\mu}g/ml)$ significantly inhibited the $TNF-\;{\alpha}$ secretion by astrocytes stimulated with $A-{\beta}-$and IL-1. These results suggest that Sgp may inhibit $TNF-\;{\alpha}$ secretion by inhibiting IL-1 secretion and that Sgp has an antiinflammatory activity in AD brain

  • The mutagenicity of pranoprofen, a new antiinflammatory agent primarily used in Japan, was evaluated by employing several different methods such as the Ames test, micronucleus test, and the sister chromatid exchange test. For the Ames test, various doses of pranoprofen (5 and 1 mg, 100, 10, and 1 ${\mu}$g per plate) were applied, with or without the mammalian liver S-9 fraction, to the S. typhimurium LT2. For the micronucleus test, 24 hours after administering the various doses of pranoprofen (200, 100, and 50 mg/kg) to male mice by aral intubation, the femura of each group were isolated and the bone marrow samples were prepared. The micronucleated red cells and the ratio of the polychromatic versus the normochroomatic cells were counted. For the sister chromatid exchange test, the maximal non-cytotoxic concentrations (10 to 0.1 mM pranoprofen) were applied to the culture media of the Chinese Hamster Ovary (CHO) cells for 24 hrs. The numbers of revertant colonies did not increase with the increasing doses of pranoprofen when teseted with various strains of S. typhimurium. In the micronucleus test employing mice, the pranoprofen was identkfied to be a non-clastogen and a non-spindle poison. In the sister chromatid exchange test employing the cultured CHO cells, the pranoprofen did not increase the incidences of chromosomal abnormality. Based on these results, pranoprofen was found to have no mutagenic activity.

  • The effect of alcoholic extracts of Costus specious (Family: Zingiberaceae) was evaluated in experimental models of pain and inflammation. Oral administration of 100, 200 and 300 mg/kg of C. specious extracts were used for the above study. Crude extracts of C. specious (300 mg/kg dose) showed maximum time needed for the response against thermal stimuli ($7.242\;{\pm}\;0.532\;s$) which is comparable to diclofenac sodium ($8.471\;{\pm}\;0.25\;s$) in the hot plate test. The MPH (Maximum Possible Analgesia) has been found to be 14.285 for 300 mg/kg dose of the crude extract while the MPH for diclofenac was 15.857 after 60 min of administration in the hot tail-flick method. The crude extract at 300 and 200 mg/kg doses showed significant reduction in acetic acid induced writhings in mice with a maximum effect of 59.661% reduction at 300 mg/kg dose which is comparable to standard diclofenac sodium (73.4%). Alcoholic extract of C. specious showed significant inhibition in serotonin and egg albumin induced hind paw oedema in rats at 100, 200 and 300 mg/kg of the crude extracts respectively (Serotonin induced edema 44.22; 53.75; 58.51%; egg albumin induced edema - 41.317; 53.892; 59.880% inhibition after 4 h respectively). The antiinflammatory effects showed by the extract were comparable to that of standard indomethacin 5 mg/kg (Serotonin induced edema 77.56%; egg albumin induced edema 77.844% inhibition after 4 h). These results suggest that the extract possesses both the anti-inflammatory and analgesic activity on mice and rat model.

  • 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.

  • Substantial evidence has accumulated that Alzheimer's disease is associated with a local inflammatory reaction in senile plaques which may be immunemediated, and includes extensive Brain Neuroglial invasion, lymphocytic infiltration, cytokine deposition. Tumor necrosis factor a (TNF-a) is a cytokine which plays an important immunoenhancing role in the local acute and chronic inflammatory response in response to a variety of stimuli. The neuropeptide, substance P, can stimulate secretion of TNF-a from Brain Neuroglial cells. Neuroglia have substance P receptors in the central nervous system. WQ investigated whether RADIX ASPARAGI inhibits secretion of TNF-a from primary cultures of Brain Neuroglial cells containing both astrocyte (∼90%) and microglia (∼10%). RADIX ASPARAGI dose-dependently inhibited the TNF-a secretion induced by substance P plus lipopolysaccharide (LPS). In cultures enriched for micoglia (>95% pure). LPS stimulated the secretion of TNF-a but substance P caused no enhancement. Because there was no synergism between substance P and LPS in the microglial cultures it is resonable to substance P madiated enhancement of TNF-a secretion. IL-1 is a modulator of TNF-a secretion in the immune system. Also IL-1 has been shown to elevate TNF- a secretion from LPS-stimulated Brain Neuroglial cells while having no effect on Brain Neuroglial cells in the absence of LPS. We therfore investigated whether IL-1 mediates the RADIX ASPARAGI inhibition of TNF-a secretion form primary Brain Neuroglial cells. Treatment of RADIX ASPARAGI to mixed cultures stimulated with both substance P and LPS decreased TNF-a secretion to the level observed with LPS alone. These results indicate that RADIX ASPARAGI possess strong antiinflammatory activity in the cental nervous system by inhibition of inflammatory cytokines secretion from Brain Neuroglial cells.
