Current studies have been reported that fruits such as berries may contain both antioxidant and antitumor polyphenols that may be important in this regard. We investigated the immunostimulatory effect of fermented blueberry (Vaccinium corymbosum L.) on cyclophosphamide-induced immunosuppression in animal model. Rats were administered blueberry yeast fermented powder (BYFP) at doses 30, 100, and 300 mg/kg for 4 weeks after cyclophosphamide (Cy) treatment, respectively. The immunomodulatory effect of BYFP were measured both in vitro and in vivo, and the changes of blood components were also analyzed. We found that BYFP recovered immunosuppression-mediated decreased liver, spleen, and thymus weights as well as up regulation of white blood cell, lymphocyte, and neutrophil in blood. Moreover, BYFP up-regulated IL-2, TNF-${\alpha}$, and IFN-${\gamma}$ pro-inflammatory cytokine production compared to immune suppressed control group, respectively. According to histological studies, BYFP regenerated significantly on Cy-mediated injured spleen at the high doses (BYFP 300) comparison with Cy-treated groups (immunosuppression). Collectively, these findings suggest that BYFP may have the potential as a dietary immunostimulatory agent.

㈜한국바이오솔루션에서 제공받은 쌀겨발효 추출물(Fermented Rice-Bran, FRB)과 현재 시판 중에 있는 제품의 주원료로 사용되고 있는 미배아대두발효 추출물(Fermented Rice-Soybean, FRS)을 대조군으로 in vitro상에서의 이 화학적 특성과 생리활성 및 항산화작용에 대하여 검토하였다. 이화학적 특성으로 총 폴리페놀 화합물과 flavonoid 함량을 측정하였고, 생리활성 및 항산화작용은 DPPH 자유라디칼 소거활성, Fe/Cu 환원력, 간장 microsome을 이용한 지질 과산화 억제활성, linoleic acid 산화 실험계를 이용하여 측정하였다. 쌀겨발효 추출물의 총 폴리페놀과 flavonoids 함량은 각각 19.92 mg/g과 11.56 mg/g으로 미배아대두발효 추출물보다 높은 수치를 보였다. 쌀겨발효 추출물은 DPPH free radical 소거 활성능에서도 69.8%로 상당히 높은 소거율을 나타내었으며 환원력 또한, 처리농도 증가와 함께 높아지는 경향을 보였다. 간장 microsome을 이용한 지질 과산화 억제활성, linoleic acid 산화 실험계를 통한 지질과산화 억제활성을 확인한 결과, 쌀겨발효 추출물이 미배아대두발효 추출물보다 우수함을 확인하였다. 따라서, 본 연구는 건강식품소재 개발을 위해 쌀겨발효 추출물의 생리활성물질과 항산화 활성을 검토하는 기초 자료로 활용될 수 있을 것이라 사료된다.

홍삼(Red Ginseng; RG)은 인삼보다 더 높은 생체 흡수율과 다양한 약리효과를 갖는 특이한 진세노사이드(Rg2, Rg3)를 함유하고 있다. 따라서 오랫동안 많은 사람들의 건강을 위해 이용되어 왔다. 또한 발효는 유효한 생리활성을 갖는 저분자의 물질들을 생성하기 때문에 많은 연구자들이 생물학적 활성에 대해 오랫동안 연구해오고 있다. 본 연구에서는 홍삼을 붉은덕다리버섯 균사체로 7일 동안 발효하였다. HPLC 분석 결과 진세노사이드 Rg1, Re 및 Rb2가 각각 0.24, 0.25, 0.16 mg/g에서 0.12, 0.1, 0.03 mg/g으로 함량 감소를 확인하였고, 홍삼 붉은덕다리 균사체배양액(Fermented Red Ginseng; FRG)의 항염, 세포 이동, 항산화, 콜라겐 타입 I 합성과 MMP-1 억제효능에 대한 생물학적 효능을 확인하였다. 그 결과, FRG는 RG보다 항염 및 cell migration 촉진효과가 더 우수하였다. FRG는 LPS로 유도된 RAW 264.7 대식세포의 NO 생성을 억제하였으며, iNOS와 IL-6의 발현을 mRNA 수준에서 억제하였다. 이 결과로 FRG는 새로운 항염소재로서 제안이 가능하다고 사료된다.

The growth inhibitory effect of wheat grain, fermented wheat grain products, red pepper powder and kochujang was examined in AGS human gastric adenocarcinoma cells. The kochujang samples were prepared by mixing red pepper powder and each fermented wheat grain products, such as first fermented wheat grain (FFWG), second fermented wheat grain (SFWG) and final fermented wheat grain (FiFWG). The methanol extract of FiFWG showed the highest growth inhibitory effects. In order to investigate the effects of fermented wheat grain products at each stage of fermentation on anticancer activity, the kochujang prepared with red pepper powder and each of FFWG, SFWG and FiFWG were fermented until reaching pH 5.1. The kochujang adjusted to pH 5.1 by fermentation increased the growth inhibitory effect; however, the kochujang prepared with FiFWG showed the highest effect. Increased fermentation time increased the growth inhibitory effect of kochujang when prepared with FiFWG. These results suggested that the anticancer effect of the kochujang on the gastric cancer cells was affected by the fermentation periods of the wheat grains. The well-fermented end products of the wheat grains seem to be one of the major components that showed anticancer activity of kochujang.

In this study, antioxidant and anti-inflammatory of fermented Houttuynia cordata Thunb and scoria mixture extract were investigated in vitro. Radical-scavenging activities of the ethanol extracts were examined by using ${\alpha},{\alpha}$-diphenyl-${\beta}$-picrylhydrazyl (DPPH) and 2,2-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid (ABTS)) radicals assay. Consequently, we confirmed that fermented Houttuynia cordata Thunb and scoria mixture extract dependent removed DPPH and ABTS radical. Also, to confirm anti-inflammatory activity of ethanol extract, we treated fermented Houttuynia cordata Thunb and scoria mixture extract on BV-2 cell with LPS. The result showed that fermented Houttuynia cordata Thunb and scoria mixture extract concentration-dependent inhibited NO production. Therefore, fermented Houttuynia cordata Thunb and scoria mixture extract showed inhibition radical oxygen activities and inflammatory and have available for a pharmacological composition on neuritis-protection and treatment.

This study was undertaken to investigate the influence of multi-probiotics, fermented ginseng byproducts and fermented sulfone as an alternative to probiotics on performance, intestinal microflora and immunity of broiler. A five weeks trial was conducted with one day old Ross${\times}$Ross broilers (n=340), divided into five groups which further divided into 4 replicates with 17 birds in each replicate. Birds were assigned to 5 dietary treatments as control, antibiotic avilamycin (AB), multi-probiotics (MP), fermented sulfone (FS) and fermented ginseng byproducts (FGB). Growth parameters were recorded on weekly basis while rest of the parameters viz. blood and faeces were collected at the end of the experiment. Growth parameters were not affected statistically by dietary treatments. However, numerically, higher body weight, splenocytes proliferation and lower total cholesterol and LDL values were found in MP treatment (P>0.05). Salmonella spp. count ($P{\leq}0.001$) and E. coli (P<0.001) concentrations in the ileum were found lowest in AB treatment while FS group showed lowest level of yeast (P<0.10) and Lactobacillus spp. ($P{\leq}0.001$). Fecal ammonia and $CO_2$ emission was significantly decreased in FGB than other dietary treatments (P<0.05). It was concluded that multi-probiotics would be valuable feed additives to improve the growth performance, Lactobacillus proliferation and immunity of broiler chicks.

Fermented Chlorella vulgaris CBT$^{(R)}$ was evaluated for its effects on egg production, egg quality, liver lipids and intestinal microflora in laying hens. One hundred and eight Hy-line Brown layers (n = 108), 80 wk of age, were fed a basal diet supplemented with CBT$^{(R)}$ at the level of 0, 1,000 or 2,000 mg/kg, respectively for 42 d. Egg production was measured daily and egg quality was measured every two weeks. Five eggs from each replicate were collected randomly to determine egg quality. Egg production increased linearly with increasing levels of CBT$^{(R)}$ supplementation (p<0.05), although there was no significant effect of treatment on feed intake. Egg yolk color (p<0.001) and Haugh unit (p<0.01) improved linearly with increasing dietary CBT$^{(R)}$. Hepatic triacylglycerol level was linearly decreased with increasing dietary CBT$^{(R)}$ (p<0.05). The supplemental CBT$^{(R)}$ resulted in linear (p<0.001) and quadratic (p<0.01) response in population of cecal lactic acid bacteria. In conclusion, fermented Chlorella vulgaris supplemented to laying hen diets improved egg production, egg yolk color, Haugh unit and positively affected the contents of hepatic triacylglycerol and the profiles of cecal microflora.

본 연구에서는 탈지대두 grits(DSG)와 B. subtilis NUC1균주로 발효시킨 탈지대두 발효물(FD)을 제조한 다음 열풍건조한 시료를 물 추출하여 이들 DSG 물추출물(DW)과 발효된 DSG 물추출물(FDW)의 항혈전 활성과 콜레스테롤 저하 효과를 알아보았다. 그 결과, FDW는 DW보다 항혈전 활성 및 혈소판의 응고 억제 효과가 더 우수하였으며, 유의적으로 높은 HMG-CoA reductase 저해활성을 가졌다. 그러나 DW와 FDW 처리군 둘다 HepG2 세포를 이용한 콜레스테롤 생합성 억제능을 보였고, 대조군에 비해 세포 내의 콜레스테롤 함량을 유의적으로 감소시켰다. 그리고 콜레스테롤 흡착능에서는 FDW만 약 90% 정도의 높은 흡착능을 보였고, DW는 콜레스테롤 흡착능을 보이지 않았다. 따라서 발효된 DSG는 원료인 DSG 보다 항혈전 및 콜레스테롤 개선 효과가 더 우수한 것으로 생각되었다.

In the present study, the anti-cancer effects of ginseng fermented with Phellinus linteus (GFPL) extract were examined through in vitro and in vivo assays. GFPL was produced by co-cultivating ginseng and Phellinus linteus together. Ginsenoside Rg3, Rh1 and Rh2 are important mediators of anti-angiogenesis and their levels in GFPL were enriched 24, 19 and 16 times, respectively, more than that of ginseng itself through the fermentation. GFPL exhibited distinct anti-cancer effects, including growth inhibition of the human lung carcinoma cell line A549, and promotion of immune activation by stimulating nitric oxide (NO) production in Raw 264.7 cells. Further evidence supporting anti-cancer effects of GFPL was its significant prolongment of the survival of B16F10 cancer cell-implanted mice. These results suggest that the GFPL may be a candidate for cancer prevention and treatment through immune activation and anti-angiogenic effects by enriching Rg3, Rh1 and Rh2.
