  • In recent, there are increasing reports about pharmacological activities of Crataegi Fructus which has been used for many centuries as medicinal and food sources in East Asia. However, its antifungal efficacy needs to be investigated. Thus, in the current study, we determined synergistic antifungal activity of the Crataegi Fructus extract (CFE) when combined with fluconazole (FLC) against disseminated candidiasis due to Candida albicans. This fungus is one of the most problematic fungal pathogens. Data resulting from a microdilution susceptibility test showed that CFE had a dose-dependent antifungal activity. When the extract was combined with FLC, the activity was synergistic. For example, the antifungal activity by the combination of CFE at $20{\mu}g/ml$ plus FLC at $0.1{\mu}g/ml$ was 4 times more effective than antifungal activity by FLC alone at the same concentration (P<0.05). In the murine model of disseminated candidiasis, the combination therapy potentiated resistance of mice, resulting in 80% of C. albicans-infected animals surviving the entire period of 40 days observation, whereas mice given CFE alone or FLC alone all died with 17 and 23 days, respectively, although they survived longer than the untreated control animals (P<0.05). The CFE's antifungal activity seemed to be related to the blockage of hyphal production of C. albicans yeast cells. In summary, CFE has a synergistic antifungal activity, which can be produced by combining CFE with FLC. Thus, our data strongly indicate that CFE may be a potential candidate as an antifungal agent for combination therapy.

  • SunBangHwalMyungEum (SBH) has the effects of subduing swelling, resolving masses and alleviating pain in traditional oriental medicine. Recent studies showed that SunBangHwalMyungEum produced anti-cancer, anti-metastasis and immuno-modulatory effects. However there is lack of studies regarding the effects of SBH on the immunological activities. The present study was conducted to evaluate the effect of SBH on the regulatory mechanism of cytokines and nitric oxide (NO) in Raw 264.7 cells. Methods : After the treatment of SBH, cell viability was measured by MTT assay, NO production was monitored by measuring the nitrite content in culture medium. Inducible nitric oxide synthase (iNOS) was determined by immunoblot analysis, and levels of cytokine were analyzed by sandwich immunoassays. Results : Results provided evidence that SBH inhibited the production of NO, iNOS, $interleukin-1{\beta}$ ($(IL-1{\beta})$), IL-6, and the activation of phospholylation of inhibitor ${\kappa}B{\alpha}$ in Raw 264.7 cells activated with lipopolysaccharide. Conclusions : These findings suggest that SBH can produce anti-inflammatory effect, which may play a role in adjunctive therapy in Gram-negative bacterial infections.

  • Generative and vegetative parts of the cactuses have had a long-lasting position in folk medicine and their effects could partly be confirmed in scientific experiments. Nowadays, the cactus, fruits, and cladodes are the focus of many studies because of their desirable properties. Therefore, the summarized reports of valuable properties of medicinal plants may be a good way to familiarize researches with a new source of drugs with lower side effects and higher efficacy. Opuntia dillenii, a well-known member of the Cactaceae family, is used as a medicinal plant in various countries and grows in the desert, semi-desert, tropical and sub-tropical areas. It shows diverse pharmacological activities such as: antioxidant, anti-inflammatory, anti-tumor, neuroprotective, hepatoprotective, hypotensive etc. OD fruit also possesses valuable constitutes for instance: betalains, ascorbic acid, total phenol, protein as well as essential elements which suggest the significant potential of this plant as a complementary therapy against several pathological conditions. This review describes experimental evidence about pharmacological and therapeutic potential of OD in order to give the basis of its application in the prevention and treatment of some chronic diseases. More studies on OD can help better understanding of its pharmacological mechanism of action to explain its traditional uses and to identify its potential new therapeutic applications.

  • Objectives : Hwangnyeonhaedok-tang (Huanglian Jiedu Tang; HHT) has been widely used for purging' 'fire' and lessening virulence of any pathogenic organism. However it has been rarely conducted to evaluate the immuno-biological activity. In this study, we evaluated anti-inflammatory effects of HHT in LPS-activated Raw264.7 cells. Methods : Cells were treated with $1\;{\mu}g/ml$ of LPS 1 h prior to the addition of HHT. Cell viability was measured by MTT assay. The production of NO was determined by reacting cultured medium with Griess reagent. PGE2 and proinflammatory cytokines were detected by ELISA. Expression of iNOS, COX-2, $I{\kappa}B{\alpha}$ and NF-${\kappa}B$ were analyzed by immunoblot analysis. Results : All three doses of HHT (0.03, 0.10 and 0.30 mg/ml) had no significant cytotoxicity during the entire experimental period. The levels of NO and PGE2 were dramatically augmented by LPS compared to control. However, HHT extract dose-dependently reduced these increases. Expression of iNOS and COX-2 protein were also decreased by treatment with HHT extract. Furthermore, HHT extract significantly reduced the nuclear translocation of NF-${\kappa}B$ which is critical in regulating inflammation through transcription of iNOS and COX-2. In addition, HHT extract reduced the elevated production of inflammatory cytokines including TNF-$\alpha$, IL-$1{\beta}$ and IL-6. Conclusions : The results in this study demonstrate that HHT extract exerts anti-inflammatory activities through the inhibition of NO, PGE2 and proinflammatory cytokines production via the suppression of NF-${\kappa}B$.

  • Objectives: Kyungok-go (KOG) is a traditional multi-herbal medicine commonly used for enforcing weakened immunity for long time. Recently, there are several reports that KOG has anti-inflammatory and immuno-stimulatory activities in many experimental models. However, the protective effects of KOG on neuronal inflammation are still undiscovered. Thus, we investigated the neuro-protective activity of KOG on lipopolysaccharide (LPS)-stimulated mouse microglia cells. To find out KOG's anti-neuroinflammatory effects on microglial cells, we examined the production of nitrite using griess assay, and mRNA expressions of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 and interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α using real time RT-PCR. In addition, to examine the regulating mechanisms of KOG, we investigated the protein expression of mitogen-activated protein kinases (MAPKs) and Iκ-Bα by western blot. KOG inhibited the elevation of nitrite, iNOS and COX-2 on LPS-stimulated BV2 cells. Also, KOG significantly inhibited the pro-inflammatory cytokines such as IL-1β, IL-6, and TNF-α on LPS-stimulated BV2 microglial cells. Moreover, KOG inhibited the activation of c-Jun N-terminal kinase (JNK), P38 and degradation of Iκ-Bα but not the activation of extracellular signal regulated kinase (ERK) on LPS-stimulated BV2 microglial cells. These results showed KOG has the anti-inflammatory effects through the inhibition on nitrite, iNOS, COX-2, IL-1β, IL-6, and TNF-α via the deactivation of JNK, p38 and nuclear factor (NF)-κB on LPS-stimulated BV2 microglial cells. Thereby, KOG could offer the new and promising treatment for neurodegenerative disease related to neuroinflammation.

  • This study aimed to evaluate the utilization of low fish meal (LFM) diet and black soldier fly (BSF) Hermetia illucens meal supplementation in LFM diet as a fish meal (FM) replacer or functional additive for juvenile olive flounder Paralichthys olivaceus. Three LFM diets were prepared to contain 30, 25, and 20% FM, respectively (designated as F30, F25, and F20). Three BSF diets were prepared by adding 2.0, 2.5, and 3.0% BSF in the LFM diets, respectively (designated as F30B2.0, F25B2.5, and F20B3.0). A total of 540 fish (initial mean body weight: 22.3±0.01g) were randomly distributed into 18 tanks (240 L) in triplicate groups and fed the experimental diets twice daily for 12 weeks. Results showed that there were no significant differences in the growth performance, feed utilization and survival among all the groups. Lysozyme activity significantly increased in F30B2.0 and F25B2.5 groups compared to their respective LFM groups. Total immunoglobulin was significantly higher in F30 group than in F20 group. Anti-protease and myeloperoxidase activities were significantly higher in F30B2.0 group than in F20 group. Innate immunity gradually decreased with decreasing FM level in all the groups. BSF supplementation significantly improved immunity compared to their respective LFM diets. Therefore, BSF could be used as an immuno-stimulant supplement in LFM diets for P. olivaceus.

  • 본 연구는 고로쇠 및 우산고로쇠 수액의 나노입자화를 통한 유용생리활성 증진에 관한 것이다. 먼저 나노입자 수액의 형태 및 크기 확인을 위하여 EF-TEM을 이용한 결과 유상이 주머니처럼 수액을 포집한 리포좀 형태를 띄고 있으며 약 200 nm 크기의 구형으로 형성된 것을 확인할 수 있었으며, 나노입자의 크기와 균일성 및 크기별 분포 측정을 위해 DLS를 이용한 결과 수십 nm에서 수천 nm의 크기를 보였고 그중 약 70%가 100~300 nm의 크기로 형성된 것을 확인하였다. 다음으로 나노입자의 세포독성 실험을 실시하였다. 일반 고로쇠 및 우산고로쇠 수액과 비교하여 큰 차이를 보이지 않았다. 이를 통해 나노입자화를 통한 세포독성의 위험은 없다고 판단하여, 인간 면역세포인 B 세포와 T 세포의 생육증진 실험을 하였다. 5일째 되는 날 가장 많은 세포의 수를 확인할 수 있었고 고로쇠 수액 보다는 우산고로쇠 수액의 면역세포 생육증진효과가 좋았다. 또한 일반 수액보다는 나노입자수액의 생육증진 효과가 크게 나타났다. Cytokine 분비량 및 NK 세포 활성의 경우에서도 위의 실험과 비슷한 결과를 얻을 수 있었다. 면역활성을 확인한 결과를 바탕으로 정상세포 독성 및 항암실험을 하였다. 인간 정상 폐세포인 HEL299에 대한 세포독성 실험 결과 수액 및 나노입자 수액 두 시료 전부 19%이하의 세포독성을 보임으로써 레시틴으로 포집한 수액의 정상세포에서의 안전성을 확인할 수 있었다. AGS, A549, Hep3B에 대한 암세포 생육억제실험결과 3가지 암세포에서 모두 수액에 비해 나노입자수액의 활성이 약 20% 증가 된 것을 확인할 수 있었다. 본 연구에서 수행한 일반 수액 및 나노입자 수액의 연구를 통하여 나노입자 수액의 기능성 소재로서의 활용성을 확인할 수 있었으며, 이를 바탕으로 더욱 다양한 생리활성 연구 및 유용생리활성 물질의 추출에 관한 연구가 이루어져야 할 것으로 생각된다.
