  • Probiotic, prebiotic, and synbiotic substances as well as microorganisms were added to infant formula in an attempt to influence the intestinal microflora with an aim to stimulate the growth of lactic acid bacteria, especially bifidobacteria and lactobacilli. Over the last 10 years, new synbiotic infant formulas containing probiotics and prebiotics have been proposed in order to simulate the effect of breast-feeding on the intestinal microflora. Owing to their synergistic effect, the new synbiotics are expected to be more helpful than using probiotics and prebiotics individually. Maintenance of the viability of the probiotics during food processing and the passage through the gastrointestinal tract should be the most important consideration, since a sufficient number of bacteria ($10^8cfu/g$) should reach the intended location to have a positive effect on the host. Storage conditions and the processing technology used for the manufacture of products such as infant formula adversely affect the viability of the probiotics. When an appropriate and cost-effective microencapsulation methodology using the generally recognized as safe (GRAS) status and substances with high biological value are developed, the quality of infant formulas would improve. The effect of probiotics may be called a double-effect, where one is an immunomodulatory effect, induced by live probiotics that advantageously alter the gastrointestinal microflora, and the other comprises anti-inflammatory responses elicited by dead cells. At present, a new terminology is required to define the dead microorganisms or crude microbial fractions that positively affect health. The term "paraprobiotics" (or ghost probiotics) has been proposed to define dead microbial cells (not damaged or broken) or crude cell extracts (i.e., cell extracts with complex chemical composition) that are beneficial to humans and animals when a sufficient amount is orally or topically administered. The fecal microflora of bottle-fed infants is altered when the milk-based infant formula is supplemented with probiotics or prebiotics. Thus, by increasing the proportion of beneficial bacteria such as bifidobacteria and lactobacilli, prebiotics modify the fecal microbial composition and accordingly regulate the activity of the immune system. Therefore, considerable attention has been focused on the improvement of infant formula quality such that its beneficial effects are comparable to those of human milk, using prebiotics such as inulin and oligosaccharides and potential specific probiotics such as bifidobacteria, which selectively stimulate the proliferation of beneficial bacteria in the microflora and the indigenous intestinal metabolic activity of the microflora.

  • Houttuynia cordata THNUB (He; Uh-Sung-Cho) is a medicinal plant which has been widely used as a component of blood-building decoctions. This study was performed to investigate the immunomodulative effect of He in mice. In vitro experiment, the mice splenocytes proliferation and three kinds of cytokines (IL-1$\beta$, IL-6, TNF- $\alpha$) production by mice peritoneal macrophages cultured with six (methanol, hexane, chloroform, ethylacetate, butanol and water) fractions of He were used to indicate the immunomodulative effect. Ex vivo experiment, the different concentrations of He water extract was orally administrated every other day for two weeks. The production of cytokines IL-1$\beta$, IL-6, TNF- $\alpha$) secreted by activated macrophages and the mice splenocytes proliferation were used as an index for the immunocompetence. The supplementation of all six fractions of He enhanced the splenocytes proliferation at the level of 6.58$\pm$1.23∼47.82$\pm$5.48 compared to that of control in the range of 1∼50 $\mu\textrm{g}$/mL. IL-1$\beta$ production was significantly increased with the supplementation of chloroform and water extract of He. Higher level of IL-6 production was detected by the supplementation of ethylacetate, butanol and water extract. TNF - $\alpha$ production was enhanced by the supplementation of all six fractions of He. From the ex vivo study, the highest proliferation of splenocytes was seen from the mice orally administrated with the He water extract at the concentration of 500 mg/kg bw In case of cytokines production, IL-1$\beta$, IL-6, and TNF- $\alpha$ release by activated peritoneal macrophages were augmented by the oral administration of He water extract. These results indicated that He may enhance the immune function by regulating the splenocytes proliferation and cytokines production capacity in mice.

  • The biological activities on human immune and cancer cell lines of the four kinds of Korean mistletoes (Korean Viscum album, var. coloratum, : Korean Viscum sp. in Quercus acutissima Carr., Korean Viscum sp. in Castanea crenata, Korean Viscum sp. in Betula platyphylla, and Korean Viscum sp. in Salix koreensis) extracts were investigated. The extracts were preparated with ethanol, and fractionated with n-butanol, ethyl acetate, chloroform, hexane, and second distilled water. Cytotoxic potencies of the fractions on human normal lung cell line (HEL 299) showed under 28% in the concentration of 0.5 mg/ml. Growth inhibition effect of the Korean mistletoe extracts on the several human cancer cell lines depends on the concentration of the extracts, and extracting solvent. The hexane, chloroform, and ethyl acetate fractions indicated a strong anticancer activity, but not in aqueous and butanol fractions. Some mistletoe fractions have a different characteristic on the cancer cell lines. Stimulation on the growth of human immuno cell lines(B cell : Raji, T cell: Jurkat) of the extracts were confirmed in the ethyl acetate, chloroform, hexane fractions, but not in aqueous system.

  • This study was conducted to examine the effect of Hwangto, Illite, and any other disease resistant materials as dietary supplements on the growth performance and immunity for growing period with 30 Hanwoo male calves weaned 75days in age. Feeding trial was conducted with 6 treatments(five heads/treatment), which were T1(Control), T2(Control + 2% Hwangto), T3(Control + 2% Illite), T4(Control + 0.04% Oligosacharides), T5(Control + 2% Charcoal powder) and T6(Control + 0.1% Chromium picolinate) for 120 days from three to seven months in age. The results obtained are summarized as follows; During the experimental period, average daily gains were 0.82 to 0.92kg, and were high in the order of T3, T6, T4, T5, T2 and T1. Especially the growth rate of calves for growing period was higher in Illite, chromium-picolinate and oligo- sacharides feeding groups than in any other groups. Average daily intakes and intake ratio to body weight of concentrates for 120days were 3.91 to 4.15kg(average 4.03kg) and 3.10 to 3.31% (average 3.21%), respectively. TDN intakes per kilogram gains were 3.20 to 3.57kg(average 3.35kg) and were smaller in the order of T5, T3, T6, T4, T2 and T1, respectively. Density of IgG in serum of calves measured by the IgG SDID Kit was 10.2 to 11.6mg/$m\ell$, and especially increase rate of IgG for experimental period was high in T3 and T5 by 6.9 and 2.8%, respectively. But incidence of disease was not found to be different by treatments. According to the above results it may be concluded that Illite is a sort of clay minerals increased the growth rate, feed efficiency and immunity of early weaned calves for growing period, but was not in unprocessed Hwangto.

  • The present study was designed to explore an immunostimulating activity of crude extracts of Macrolepiota procera, and a combination therapy of cisplatin and Macrolepiota procera extracts which can potentiate the anti-cancer activity of cisplatin. For these, water extraction of Macrolepiota procera were performed at $4^{\circ}C$(MPE-4) and $100^{\circ}C$(MPE-100). In experimental metastasis of colon26-M3.1 cells, prophylactic intravenous administration of MPE ($80-2,000{\mu}g$/mouse) inhibited tumor metastasis compared with tumor control. Peritoneal macrophages stimulated with MPE produced IL-12 as well as induced tumoricidal activity. In an analysis of NK-cell activity, i.v. administration of MPE ($200{\mu}g$/mouse) significantly augmented NK cytotoxicity to YAC-1 tumor cells. The combination treatments of cisplatin ($20{\mu}g$) and MPE ($100{\mu}g$) exhibited prolongation of lifespan in colon26-M3.1 tumor bearing mouse. These results suggested that MPE stimulate immune system non-specifically and application as adjuvant in cancer treatment.

  • Mubigangjang-Ju (MGJ) is a traditional wine, fermented extract of Cynanchum wilfordii, Angelicae gigantis and Epimedium koreanum etc. In the present study, we comparatively investigated the immune-enhancing effect of fermented extract (MGJ) and water extract (WE). Forced swimming test (FST) was performed as a model of activity test in mice and measured blood urea nitrogen (BUN), aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactic dehydrogenase (LDH), glucose (Glc) and total protein (TP) in the serum. Each extracts were orally administered into mice, 10 ㎖/kg, once per day for 7 days using a feeding atraumatic needle. After 3 days, on FST, the immobility time was decreased in the MGJ-fed group (133.7±18.6 s) in comparison with the saline-fed group (155.8±16.6 s). After 7 days, the immobility time was significantly decreased in the MGJ-fed group (105.3±12.7 s) in comparison with the saline-fed group (171.3±8.1 s). In addition, the content of AST was significantly decreased and the contents of BUN, ALT and LDH in the blood serum was also decreased. Whereas, the content of Glc tend to increase and TP level was not changed. However, WE had no effect on all experiments. The present results suggest that fermented extract was more effective than water extract and it may be useful for the immune-enhancing agent.

  • To evaluate whether active components produced by solid fermentation of Phellinus baumii and Ephedra sinica have potential in ameliorating allergic symptoms in mice, we tested anti-allergic activities in a dinitrofluorobenzene (DNFB)-induced allergic mouse model. DNFB-induced allergic symptoms werereduced to about 50% of control levels by active components produced by solid fermentation of Phellinus baumii and Ephedra sinica, as evaluated by measuring the width of epidermal swelling. H&E staining also revealed that these active components markedly reduced allergic symptoms in the epidermis of the ear. The results indicate that active components produced by solid fermentation of Phellinus baumii and Ephedra sinica have the potential to ameliorateallergic symptoms, and may be useful biomaterial(s) in the neutraceutical or cosmeceutical industry.

  • Electroacupuncture(EA) is known to affect various autonomic functions such as blood pressure regulation, immune modulation and the improvement of disorders concerning autonomic functions. The aim of the present study was to establish whether EA has an immune-enhancing effect. ICR mice weighing 20 to 25g were divided into four groups: Group I(n=6), blank; Group II(n=6), control; Group III(Zusanli, n=6), low frequency-EA(10Hz of electrical stimulation), and Group IV(Zusanli, n=6), high frequency-EA (100Hz of electrical stimulation). For this study, we investigated expressions of spleen heat shock protein (HSP)70, HSP90 and secretions of cytokines. A Forced Swimming Test(FST) was performed as a model of activity test in mice. After three days of the FST, 10Hz EA($114.8{\pm}7.27s$) and 100Hz EA($147.5{\pm}1.29s$) immobility time significantly decreased compared with the control group($157.2{\pm}1.48s$). After seven days, 10Hz EA($124{\pm}1s$) and 100Hz EA($141{\pm}4.24s$) also significantly decreased immobility time compared with the control group($168{\pm}7.93s$). 10Hz EA and 100Hz EA increased the expression of HSP70 but did not change that of HSP90. 100Hz EA increased secretions of IL-6 and IL-12 compared with the control group however, 10Hz EA failed to change those of IL-6 and IL-12. The present results suggest that EA may be useful for down-regulated immune diseases.

  • Purpose : This study was designed to examine the blood glucose control and increase immunity effects of ${\beta}-glucan$ added cooked barley noodle in streptozotocin-induced diabetes mice with a high-fat diet. Method : Forty-eight male ICR mice (6-week-old) were fed AIN-93 diet for 4 weeks. Mice were divided into six groups: normal, diabetic, cooked barley noodle, ${\beta}-glucan$ (5 %) control and two experimental groups (${\beta}-glucan$ 2.5 % and 5 %, cooked barley noodle contained diet with ${\beta}-glucan$ 2.5 % and 5 % w/w). Diabetes mellitus was induced by intraperitoneal injection of streptozotocin (150 mg/kg). Result : Blood glucose level was significantly decreased in groups consuming cooked barley noodles, but no significant difference was exhibited in diabetic and ${\beta}-glucan$ control group. These results were in accordance with the result of oral glucose tolerance test. Blood interfereon $(IFN)-{\gamma}$ was measured in order to identify increase immunity effect of ${\beta}-glucan$ in diabetic mice. Inhibited $IFN-{\gamma}$ concentration was recovered in cooked barley noodle and ${\beta}-glucan$ control group. Moreover, $IFN-{\gamma}$ concentration was dramatically elevated in ${\beta}-glucan$ contained cooked barley noodle groups in a dose dependent manner. Streptozotocin induced AST and ALT activities were decreased in ${\beta}-glucan$ contained cooked barley noodle groups with a strong lipid lowering effect. Conclusion : Although addition of ${\beta}-glucan$n did not give any significant synergistic effect on cooked barley noodle in blood glucose regulation, suppressed $IFN-{\gamma}$ production by STZ was dramatically enhanced by ${\beta}-glucan$ supplementation in a dose dependent manner. Liver function and blood lipid profile were also in accordance with the increase immunity effect of ${\beta}-glucan$. Consequently, ${\beta}-glucan$ added cooked barley noodle can be consumed as good diets for patients with chronic diseases with reduced immunity.
