Although water is an essential component of the human body and is involved in many physiological processes, the effect of a steady and sufficient water intake on blood components has not well elucidated. Therefore, we investigated the changes in hematological parameters, high-sensitivity C-reactive protein (hs-CRP), and immunoglobulin G (IgG) after water intake in 13 healthy adults. They were divided into two groups: The control group (N=4), which consumed water ad libitum, and the experimental group (N=9), which consumed 2 L of water per day. Two weeks later, blood cell counts, hematocrit, and hemoglobin content had increased in the experimental group, although not significantly (p>0.05); however, there was a significant increase in the mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) (p<0.05; and p<0.01, respectively), and a significant decrease in the mean platelet volume (MPV) (p<0.05). Of the immunologic parameters, a non-significant decrease in the concentration of hs-CRP, an indicator of cardiovascular disease risk, was observed (p>0.05). However, there was a dramatic and significant increase in the concentration of IgG (p<0.05). In conclusion, a steady and sufficient water intake may contribute to alleviate anemia by increasing hemoglobin. Additionally, it may decrease the risk of cardiovascular disease by decreasing platelet activation and concentration of hs-CRP. Furthermore, a steady intake of water may improve immune function by increasing the concentration of the components of humoral immunity.

Background: Polysaccharides are the most important functional constituent in Astragalus membranaceus. The purpose of the present study was to evaluate the effect of polysaccharides isolated from the aboveground parts of A. membranaceus (AMA) and polysaccharides isolated from the roots of A. membranaceus (AMR) immune function by modulated cytotoxic T cell and Th1- and Th2-related cytokines kinetics. Methods and Results: Sprague-Dawley rats were randomly divided into exhaustive exercise case groups and non-exercise case, AMA and AMR samples were administered orally for 30 days (500 mg/kg/day and 10 mg/kg/day, respectively) and were compared to those rats in the groups fed commercial sports drink (SPD) and vehicle. Both exhaustive exercise groups and non-exercise groups had a lower ratio of $CD4^+$ and $CD8^+$ cells in the spleens of the rat fed AMA and AMR compared to those in the rats fed SPD and vehicle group. These results suggested that AMA and AMR promote an increase in the proportion of cytotoxic T cells. The IL-4-producing T lymphocytes decreased significantly in the AMR (10 mg/kg/day) group compared to SPD and vehicle, whereas the AMA group increased the IL-4 concentration more than the SPD and vehicle in exhaustive exercise group. However, the populations of IFN-${\gamma}$-producing T lymphocytes of AMR and AMA increased. AMA decreased the concentration of IFN-${\gamma}$ to inhibit the Th1 response and thereby increased the concentration of IL-4 to induce a Th2 response that was related to humoral immunity in the non-exercise group. Conclusions: These results showed that, in addition to Th1/Th2 regulation, AMR and AMA played an important immuno-modulatory role after exhaustive exercise-induced Th1/Th2 lymphocyte imbalance, which might be correlated with cytokine producing immunoregulatory cells.

We have investigated the immunomodulatory activity of water extracts of Acanthopanax divaricatus var. alveofructus in male ICR mice. Mice were administrated with fermented milk containing freeze-dried extract 3 mg/Kg (A), 9 mg/kg (B), 27 mg/Kg (C) per body weight with A. divaricatus var. alveofructus (loots : leaves : stem) : Codonopsis lanceolata = (5 : 2 : 1.5) : 1.5 for 7 and 10 weeks, respectively. Body weight, relative organ weight, cellularity of lymphoid organs, plaque- forming cell (PFC) assay, agglutination (AGG) test and lymphoproliferation were examined in various groups of animals. Any significant differences of body weight gain were not recorded in the tested ICR mice. There was significant different (p<0.05) in the spleen index in B group of 10 weeks and C group of 7 weeks fed mouse. The thymus gain weight was increased during administration of the extract, but there was no significant increase on other organs gain. Humoral immunity as measured by PFC showed more decreased PFC level in 10 weeks than in 7 weeks. In the HT, A. divaricatus var. albeofructus extract also showed a significant increase (p<0.05) in C group of 10 weeks. Administration of extracts from A. divaricatus var. albeofructus increased significantly in the production of IgG antibodies on the mice immunized with SRBC in B group of 7 and 10 weeks (p<0.05).

We have previously shown that crude water extract of Euonymus alatus (EA) had strong prophylactic effect against chemically induced-and tumor cell implanted-cancer, and that the mechanisms responsible for its antitumor effects were due to nonspecific enhancement of the NK cell activities and the cell mediated immunity. However, it was unknown that any components of crude extract did work so, since it consisted of several components. In this paper, we fractionated the crude watar EA-extract into several fraction such as hexane-, ethylether-, ethyl acetate-, n-butanol- and water soluble-fraction, and screened the immune regulating activities of each fraction by the evaluation of lymphokine production and activated lymphocyte proliferation. As a result of the component fraction of EA-extract, it was found that n-butanol fraction was a potent immunostimulator, and the remained water soluble fraction also contained some stimulator, But, other fraction did not showed any remarkable effect. It is therefore suggested that EA-glycosides in n-butanol fraction may be new one of the potent biological response modifiers. The present study was also undertaken in an efforts to investigate the effects of elm-bark(EB, Ulmus clavidiana var japonica), which has been used for curing ulcer and inflammation as a folk medicine without any kind of experimental evidence to support this, on the cellular- and humoral-immune responses, lymphocyte function and NK cell activities in mice. Regardless of time and duration of EB-treatment, Arthus reaction and antibody response to SRBC were not modified by EB, but delayed hypersensitivity to SRBC was significantly enhanced only when EB was treated prior to SRBC-sensitization. EB slightly inhibited the proliferation responses of splenocytes to PHA-stimulation, but it significantly augmented the responses of these cells to S aureus Cowan 1 and Con A-activation, and these effects were manifested only when EB was added at culture initiation. EB did not influence Ig secretion of spleen cells but it significantly augmented the Con A-induced 1L 2 and MIF production of splenocytes. NK cell activities of splenocytes were markedly riled when effector cells were pretreated with EB and this augmentation was dine to the increase of binding affinity of effector cells to target cells and the target cell lytic activities of effector cells. These results led to the conclusion that EB triggers increase of cellular immune responses, such as delayed hypersensitivitiy, lymphokine production and NK cell activities. Also these results suggested that EB contains potent immune stimulants, which may provide the rational basis for their therapeutic use as one of the new biological response modifiers.

The immunoenhancing effect of CLA isomers (CLA mixture, 10t-12c CLA, 9c-11c CLA, 9c-11c CLA, and 9t-11t CLA) on phagocytic activity of porcine peripheral blood leukocytes was examined. The phagocytic activities of peripheral blood mononuclear cells (PBMC) and polymorphonuclear cells (PMN) were analyzed by a flow cytometry system. The direct treatments of CLA isomers have no effect on phagocytosis of PMN as well as PBMC composed of approximately 10% monocytes and 90% lymphocytes. However, the phagocytic activities of PMN and monocyterich fraction from PBMC were remarkably enhanced by culture supernatant from PBMC treated with CLA mixture, 10t-12c CLA and 9c-11t CLA but not 9c-11c CLA and 9t-11t CLA. The phagocytic activity of PBMC was not enhanced by culture supernatant from PBMC treated with all CLA isomers. These results indicated that CLA isomers such as CLA mixture, l0t -12c CLA and 9c-11t CLA have an enhancing effect on phagocytosis of PMN and monocytes, which may be mediated through active humoral substances produced by CLA-stimulated PBMC. This study suggested that CLA stimulates PBMC to elaborate soluble factor(s), which may be an important mechanism for the enhancement of phagocytosis in non-specific immunity.

The concept of innate immunity in insects which refers to the first line of host defense constitutes the humoral and cellular components which are involved in recognition and actively participate in the elimination of the intruding foreign micro- or macro-organisms. Several recent studies suggest that juvenile hormone (JH) modulates the cellular immune reactions in response to pathogen. In this study, pyriproxyfen (a JH agonist as an insect growth regulator) was tested in its any inhibitory effect on the immune reactions of the beet armyworm, Spodoptera exigua. To this end, five different hemocyte morphotypes of final instar S. exigua were identified by phase contrast microscopy. Plasmatocytes and granular cells, which constitute about 90% of the total hemocyte count, were prominently distinguished based on their basophilic/acidophilic nature using Giemsa stain. The role of pyriproxyfen on the functional ability of hemocytes was analyzed using FITC-labeled Providencia vermicola for the phagocytic potential of the hemocytes. Both granular cells and plasmatocytes exhibited phagocytosis behavior. Pyriproxyfen significantly inhibited the phagocytosis of both cell types, proposing its novel action as an immunosuppressant.
