  • Objectives : This study was to observe anticancer and related immunomodulatory effects of Kwibi-tang extracts (KBTe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Methods : Three different dosages of KBTe, 50, 100 and 200 mg/kg were orally administered once a day for 42 days from 11 days after tumor cell inoculation. Six groups, each of 8 mice per group were used in the present study. Changes in body weight, tumor volume and weight, lymphatic organs (spleen and popliteal lymph node), serum interferon (IFN)-${\gamma}$ levels, splenocytes NK cell activity and peritoneal macrophage activities, splenic tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-10 contents were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. The results were compared with a potent cytotoxic anticancer agent, 5-FU (5-Fluorouracil) 30 mg/kg, intraperitoneal treatment (3-day intervals for 42 days, the optimal effective treatment regimes already confirmed). Results & Conclusions : This study suggest that over 50 mg/kg of KBTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory effects. Although relatively lower anticancer effects were observed in KBTe 200 mg/kg treated mice as compared with 5-FU 30 mg/kg treated mice, no meaningful favorable immunomodulatory effects were observed after 5-FU treatment in the present study.

  • Identification of novel probiotic strains is of great interest in the field of functional foods. Specific strains of heat-killed bacteria have been reported to exert immunomodulatory effects. Herein, we investigated the immune-stimulatory function of heat-killed Lactobacillus plantarum KCTC 13314BP (LBP). Treatment with LBP significantly increased the production of $TNF-{\alpha}$ and IL-6 by macrophages. More importantly, LBP was able to enhance the phagocytic activity of macrophages against bacterial particles. Activation of p38, JNK, ERK, $NF-{\kappa}B$, and STAT3 was involved in the immunomodulatory function of LBP. LBP treatment significantly increased production of $TNF-{\alpha}$ by bone marrow-derived macrophages and splenocytes, further confirming the immunostimulatory effect of LBP in primary immune cells. Interestingly, the immunomodulatory effects of LBP were much stronger than those of Lactobacillus rhamnosus GG, a well-known probiotic strain. These results indicate that LBP can be a promising immune-enhancing functional food agent.

  • Bifidobacterium strains can provide several health benefits, such as antimicrobial and immunomodulatory effects. Some strains inhibit growth or cell adhesion of pathogenic bacteria, including multidrug-resistant bacteria, and their antibacterial activity can be intensified when combined with certain antibiotics. In addition, some strains of bifidobacteria reduce viral infectivity, leading to less epithelial damage of intestinal tissue, lowering the virus shedding titer, and controlling the release of antiviral substances. Furthermore, bifidobacteria can modulate the immune system by increasing immunoglobulins, and inducing or reducing pro- or anti-inflammatory cytokines, respectively. In particular, these anti-inflammatory effects are helpful in the treatment of patients who are already suffering from infection or inflammatory diseases. This review summarizes the antimicrobial effects and mechanisms, and immunomodulatory effects of Bifidobacterium strains, suggesting the potential of bifidobacteria as an alternative or complementary treatment option.

  • The object of this study was to observe anticancer and related immunomodulatory and anticachexic effects of Insamyangyoung-tang aqueous extracts (ISYYTe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Changes on the tumor volume and weights, lymphatic organ(spleen and popliteal lymph node), serum interferon (IFN)-${\gamma}$ levels, splenocytes and peritoneal macrophage activities (NK cell activity), splenic tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-10 contents, splenic T-lymphocyte subsets (CD3+, CD4+ and CD8+) and TNF-${\alpha}+$ cells were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. In addition, changes on the body weights, epididymal fat weights and serum IL-6 levels were also detected with the thicknesses of deposited cervical brown adipose tissue and their mean diameters to monitor the tumor-related anticachexic effects. The results obtained in this study suggest that over 50 mg/kg of ISYYTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory and anticachexic effects. However, detail mechanism studies should be conducted in future with the screening of the biological active compounds in this herb.

  • Egg yolk is widely used to extract lecithin, which is utilized in the food and cosmetics industry. After lecithin is removed, the rest of egg yolk is generated as a by-product. Thus, it is necessary to properly utilize it. In this study, egg yolk protein extracts were produced using ethanol (EYE-E) and water (EYE-W). Their antioxidant and immunomodulatory effects were then evaluated. Antioxidant activities of EYE-E and EYE-W were determined using cellular antioxidant capacity (CAC) assay and comet assay. EYE-E and EYE-W showed significant (p<0.05) scavenging effects on intracellular reactive oxygen species (ROS) in a dose dependent manner. At a concentration of 50 ㎍/mL, EYE-W showed higher (p<0.05) antioxidant activity than EYE-E. EYE-E and EYE-W also exhibited protective effects against DNA damage caused by oxidative stress. After treatment with EYE-E and EYE-W, DNA damage level of 48.7% due to oxidative stress was decreased to 36.2% and 31.8% levels, respectively. In addition, EYE-E and EYE-W showed immunomodulatory effects by regulating Th1 cytokines (TNF-α and IL-2) and Th2 cytokines (IL-10 and IL-4) in Balb/c mouse splenocytes. These data suggest that EYE-E and EYE-W could be used as functional food ingredients with excellent antioxidant and immunomodulatory activities in the food industry.

Methods : Three different dosages of ISYYTe, 50, 100 and 200 mg/kg were orally administered once a day for 42 days from 11 days after tumor cell inoculation. Six groups, which are intact control, tumor bearing control, 5-fluorouracil (FU) 30 mg/kg, ISYYTe 50 mg/kg, ISYYTe 100 mg/kg, ISYYTe 200 mg/kg, each of 8 mice per group were used in the present study. Changes on the body weight, tumor volume and weight, lymphatic organ (spleen and popliteal lymph node), serum interferon (IFN)-${\gamma}$ levels, splenocytes NK cell activity and peritoneal macrophage activities, splenic tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-10 contents were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. Results : As results of ISYYTe 50, 100 and 200 mg/kg treatment, decreases in the tumor volumes and weights were detected. At histopathological observations, decreases of tumor cell volumes in tumor masses were dose-dependently decreased mediated by increases of apoptosis among tumor cells by treatment of all three different dosages of ISYYTe. As results of tumor cell inoculation, marked decreases of spleen and popliteal lymph node weights, serum IFN-${\gamma}$, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents and splenocytes were observed with histopathological atrophic changes of spleen and popliteal lymph nodes. Conclusions : Over 50 mg/kg of ISYYTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory effects. Although relatively lower anticancer effects were observed in ISYYTe 200 mg/kg treated mice as compared with 5-FU 30 mg/kg treated mice, there are no meaningful favorable immunomodulatory effects were observed after 5-FU treatment in the present study.

  • This study examined the immunomodulatory effects of milk fermented with based on the synbiotic interaction between Cudrania tricuspidata leaf extract (CT) and Lactobacillus gasseri 505. Raw 264.7 macrophages were treated with milk (Control), milk supplemented with 0.2% CT (CT-milk), or CT-milk fermented with L. gasseri 505 (FCT). FCT-treated cells showed higher NO production than the other groups. ELISA revealed that FCT produced the highest enhancement of the production of pro-inflammatory cytokines such as $TNF-{\alpha}$, $IFN-{\gamma}$, $IL-1{\beta}$, IL-6, IL-2, IL-12, and IL-10. Furthermore, FCT also increased the gene expression of pro-inflammatory mediators such as iNOS and COX-2 in a concentration-dependent manner. Collectively, these results indicate that the synbiotic interaction between CT and L. gasseri 505 might enhance their immunomodulatory effects of fermented milk.

  • Objective : Sparassis crispa has been recognized for its therapeutic value since the late 20th century because of its high β-glucan content. Since then, researches have been conducted on the pharmacological effects but most of these are individual studies on the effects of β-glucan from S. crispa and the comprehensive reviews are lacking. The purpose of this study was to review the compounds composition and pharmacological effects of S. crispa. Methods : This review analyzes the papers about chemical and nutritional composition and pharmacological effects of S. crispa. The data in this review is based on selected papers after reviewing all studies containing the keyword "sparassis crispa" for PubMed, NDSL, and J-Stage published before February 2019. Results : S. crispa is composed of protein, lipids, and carbohydrates. Most of the compounds are carbohydrates and the highest content is β-glucan. More than 40% of the dried fruiting body of S. crispa is composed of β-glucan. In addition, it contains polyphenols, flavonoids, terpenoids and phthalide-based compounds. Broad spectrum of its pharmacological actions have been established which include immunomodulatory, anticancer, antiinflammatory, antioxidant, hypoglycemic, antiobesic and neuroprotective effects. Conclusion : The most studied fields have been shown to have immunomodulatory and anticancer effects by inhibiting the proliferation of cancer cells and angiogenesis and increasing hematopoitic responses. Unique structure and characteristic of high molecular weight β-glucan are considered to have high immunomodulatory effects of S. crispa. And low molecular fractions or phthalides of S. crispa also have antioxidant, immunomodulatory and anticancer effects.
