The aim of this study was to investigate the effects of several herbal prescriptions in patients with allergy or atopic disease, such as atopic dermatitis, asthma and allergy rhinitis and others, on the blood immunological parameters and to verify the safety of long-term use of herbal medicine. Eighty one patients with allergy or atopy disease who taken herbal medicine at least for 2 months were compared with patients who taken same medicine with no allergy & atopy disease (n=14) and normal healthy subjects (n=22). According to the comparison of immunological parameters change, the data showed that herbal medicine decreased IgE (P=0.003), Eosinophil ratio (P<0.001) and count (P<0.001) of White Blood Cell (WBC) and did not affect to the liver cell enzymes in blood. This results indicated that herbal medicine decreased immune hypersensitivity and improved chronic inflammation related to blood immunological parameters of allergy or atopy diseases. In addition, herbal medicine seemed to be safe to the liver function for long-term use.

In the view of oriental medicine, the liver is the general of the army in its function of protecting against the enemy. So this concept is very closely associated to the immunological function. Its relations with immunological function are as follows. 1. The liver produces most of the proteins and converts them with hepatocytes, composes 80% in total reticuloendothelial system with Kuffer cells & endothelial cells and has typical structure of sinusoidal vessels closely related with the blood system. 2. The liver plays an important role in innate immunity with Kuffer cells as well as with the molecules that the liver produces, related to complementary systems. 3. In the embryonic period, the liver is associated with immune associated cell growth and their maturation. After birth, it is associated with removing old red blood cells and with systematically modulating immune system through hormone metabolism. 4. The liver controls the autoimmune disease resulting from immune complex by removing molecules like immune complex. 5. In the processing of blood 19A from the digestive system, the liver has an important role in protecting the body from unnecessary immune responses. 6. In the oriental medical view, liver plays a major role in the immune function by storing blood and dispersing stagnated hepatoqi with the help of the kidneys and spleen.

Background: Although neuropathic pain is a severe and common pain, its pathophysiology has not been elucidated yet. Studies in recent years have focused on the immune system's role in the pathogenesis of neuropathic pain. The aim of this study was to investigate the role of immunological mechanisms in neuropathic pain and the effect of pregabalin by measuring immunological marker levels in peripheral blood before and after pregabalin treatment in postherpetic neuralgia (PHN) patients with neuropathic pain. Methods: Forty patients diagnosed with PHN were included in the study. CD4, T follicular cells (Tfh: CD4⁺CXCR5⁺PD1⁺), Th17 (CD4⁺CCR6⁺ and CD4⁺IL17A⁺), regulatory T cells (Treg: CD4⁺ CD25⁺foxp3⁺), Th1 (CD4⁺ CXCR3⁺ and CD4⁺ IFN-γ⁺) and Th2 (CD4⁺ IL-4⁺) cell ratios were measured in peripheral blood samples before treatment and after 3 months of treatment. Results: When immunological marker and inflammation parameter levels were compared before and after treatment, the helper T cell ratio (CD3⁺, CD4⁺) was 30.28 ± 12.27% before treatment and 34.93 ± 11.70% after treatment, so there was a statistically significant increase (P = 0.028). Th17 was 4.75 ± 5.02% before treatment and 5.80 ± 3.13% after treatment, and there was a statistically significant increase (P = 0.036). Conclusions: Immunological mechanisms play an essential role in the pathogenesis of neuropathic pain, immunologically based treatment approach will be the critical point of treatment.

In order to develop new bioactive functions ginseng extract, it was studies whether the ginseng extracts on the induction of immunological tolerance In mice. Oral immunologic tolerance was induced by the secondary exposure of egg albumin + alum following gastrointestinal exposure nth egg albumin In mice, and the effect on anti EA antibody in blood, 7 cell subset in spleen were Investigated. The results obtained were as follows. EA group and EA + GE group was capable of conferring tolerance, contained a profound for 5 weeks experimental but saline group restricted to induce tolerance. GE group did not show the activity of tolerance by the first immunogens exposure, but induced the tolerance by the secondary exposure. And also spleen T cells, CD 8+ and CD 4+ were decreased. These results suggested that ginseng may affect the induction of immunological tolerance, which may be associated proliferative response of CD 4+ and CD 8+ in splenocyte.

Amorphous silica particles, whose applications are increasing in many biomedical fields, are known to be less toxic than crystalline silica. In this study, the inflammatory effects of amorphous silica nanoparticles were investigated using 30-nm amorphous silica nanoparticles and human peripheral blood mononuclear cells (PBMCs) or purified monocytes. As a result, production of IL-$1{\beta}$ and IL-8 were increased. In addition, the mitochondrial reactive oxygen species (ROS) was detected, which may lead to mitochondrial membrane disruption. Most importantly, inflammasome formation was observed. Therefore, these results provide immunological information about amorphous silica nanoparticles and suggest that amorphous silica nanoparticles can evoke innate immune reactions in human monocytes through production of IL-$1{\beta}$ and IL-8.

Brazilin was examined for its effects on the induction of immunological tolerance. Brazilin was administered to C57BL/6 female mice for 2 consecutive days before the immunization with high dose SRBC (109 cells) which can produce immunological tolerance. Delayed type hypersensitivity, IgM plaque forming cells, ConA induced IL-2 production and mitogen- or antigen-induced proliferation of lymphocytes were measured as evaluation parameters. Administration of brazilin prior to immunization could keep the DTH and IL-2 production almost optimaly immunized levels. Brazilin also inhibited the elevation of non-specific suppressor cell activity. ConA induced proliferation of splenocytes in high dose SRBC immunized mice was significantly decreased by pretreatment of brazilin. And this might be one of the reason for augmentation of DTH by brazilin. However, IgM plaque forming cells were not affected by the treatment of brazilin. These results indicate that brazilin prevents the induction of mmunological tolerance caused by high dose SRBC by suppressing the elevation of suppressor cell activity and by inhibiting the decrease in IL-2 production in C57BL/6 female mice.

Atopic dermatitis is an allergic inflammatory skin disease caused by aberrant and overreactive immune responses including overactivation of $T_H2$ immune responses, high levels of IgE as well as proinflammatory cytokines and chemokines. We examined whether BHOSB, a traditional herbal medicine, has modulatory effects on various immunological factors related to pathogenesis of atopic dermatitis in ONCB treated NC/Nga mice. Oral administration of BHOSB at the concentration of 10.8 mg/mouse/day significantly inhibited the production of IgE compared with control, and the levels of IgG2a and IgG2b, but not IgG1, were also significantly reduced. Production of IL-6 and TNF-a was greatly decreased. The results from flowcytometry of peripheral blood mononuclear cells indicated that the percentages of C03+C069+ cells and C04+ were significantly decreased by BHOSB. Theses results suggested that BHOSB has suppressive effects on aberrant and overreactive immunological activities in ONCB-induced dermatitis mice of NC/Nga.

The cord blood serves as a vehicle for the transportation of oxygen and nutrients to the fetus. In the past, the human cord blood has generally been discarded after birth. However, numerous studies have described the regenerative ability of the cord blood cells in various incurable diseases. The umbilical cord blood (UCB)-derived stem cells are obtained through non-invasive methods that are not harmful to both the mother and the fetus. Furthermore, the cord blood stem cells are more immature than the adult stem cells and expand readily in vitro. The mesenchymal stem cells (MSCs) have the capacity to differentiate in vitro into various mesodermal (bone, cartilage, tendon, muscle, and adipose), endodermal (hepatocyte), and ectodermal (neurons) tissues. This review describes the immunological properties of the human UCB-MSCs to assess their potential usefulness in the allogeneic transplantation for the regenerative medicine.
