  • The purpose of this research was to investigate the effects of supercritical fluid extract of Kamichungbieum (SFE) on immune reaction. SFE did not affect the subpopulation of murine splenocytes and increased the production of interleukin-2 in serum. Also, SFE inhibited the influx of Ca/sup 2+/ into mast cells and the release of histamine from mast cells. Furthermore, SFE decreased the phagocytic activity of murine macrophages, These results indicate that SFE may be useful for the treatment of allergy related disease via inhibition of histamine release from mast cells and decrease of phagocytic activity of murine macrophages.

  • Effects of Allolobophora caliginosatrapezoides (Ac) polysaccharide fractions on the inflammation and hypersensitivity were studied in vivo. It showed that Ac polysaccharide fractions have the significant inhibitory activities of inflammation and hypersensitivity; They inhibited significantly the carrageenin-induced paw edema and acetic acid-induced writhing syndrome. They also inhibited significantly the Arthus reaction and delayed hypersensitivity in the sheep red blood cell-sensitized mice in accordance with the inhibition of haemaglutinin titer, haemolysin titer, plaque-forming cells and rosette-forming cells. They also improved markedly the oxazolone-induced dermatitis in rats dose-dependently. As the above results, it exhibited that Ac polysaccharide fraction inhibited not only humoral immune response, but also cell-mediated immune response. It seemed that methanol and ether extracts have also another physiological active agents.

  • Antibiotics are known to be able to cause hypersensitivity reactions through various mechanisms. We present a case of drug-induced immune thrombocytopenia (DITP) and anaphylactic shock occurring simultaneously in a dog after the administration of two classes of antibiotics, namely trimethoprim-sulfamethoxazole (TMP-SMX) and amoxicillin-clavulanate (AMC). The patient recovered completely from DITP on discontinuation of TMP-SMX and the anaphylactic shock caused by AMC was treated with intensive care. DITP is a rare adverse drug reaction (ADR), and anaphylactic shock is a life-threatening ADR. This is the first case report of a dog manifesting two types of hypersensitivity reactions caused by two antibiotics.

  • Food allergy is defined as an immunologically-mediated adverse reaction to food.The food allergy as a clinical entity has been recognized for many years, although there is yet no general consensus as to the incidence of this syndrome. One difficulty in studying food allergies has been the lock of a reasonable animal model in which reactions could be induced by orally administrating foods. It has been generally accepted that the initial target for an immediate reaction to food is the mast cells, within the gastronitestinal mucosa, and such cells are sensitize in vivo by food-specific immunoglobulin(Ig) E. Degranulation of these cells facilitates the entry of an antigenic epitope into the lymphatic system and blood stream, thereby causing further degranulation of the mast cells and basophils throughout the boy. Accordingly, the author attempted to develop an animal model that is indicative of evaluating IgE-mediated immediate hypersensitivity. It is also necessary to evaluate the effects of nutritional envioronments on dietary protein-dependent allergy and the regulatory mechanisms of dietary fats on IgE-mediated immune response. In this review, animal models to evaluate a food ingredient, effects of dietary fats and curcuminoids, milk whey protein hydrolysates on allergic reaction, and effect of dietary fat in splenic immune cells are presented.

  • Objective : To investigate immune enhancing effects of Boummyunyuck-dan (BMD) Methods : In this study I investigated the effect of BMD on cell proliferation and viability. In addition, I investigated production of cytokines (IL-2, IL-4 and $IFN-{\gamma}$), NO, and $TNF-{\alpha}$ in human T-cell leukemia, MOLT-4 cells. The cells were cultured for 24h in the presence or absence of BMD. Result : BMD increased the cell viability by 15% (P<0.05) and enhanced IL-2, IL-4 and $IFN-{\gamma}$ production compared with media control in a dose-dependent manner (P<0.01) at 24h. BMD also increased mRNA and protein expression levels of $IFN-{\gamma}$ in MOLT-4 cells. In addition, I also assessed the effects of BMD on production of NO and $TNF-{\alpha}$ from the peritoneal macrophages because NO and $TNF-{\alpha}$ as a potent macrophage-derived immune reaction regulatory molecule has received increasing attention. However, BMD had no effect on NO and $TNF-{\alpha}$ production in the cells. Conclusion : These data indicate that BMD has some immune-enhancing effect, and that its action may be due to the proliferation and cytokine production of T cells.

  • Gekko has been used for several diseases including cancer in Oriental medicine and fork herbalogy. Nevertheless, its origin as herbal medicine and its efficacy and mechanism as anti-tumor drug have not yet been thoroughly reported in Korea. This study aimed to investigate anti-tumor effect of Gekko through selected articles from cqvip database in China. In vitro and In vivo, Gekko could obviously inhibit tumor growth, induce tumor cells apoptosis, reduce micro-vessel density in tumor tissue through down regulating VEGF & bFGF protein expression, promote cytotoxicity of lymphocyte. Gekko could improve survival rate, relive clinical symptoms, improve quality of life, and relieve anti-tumor treatment reaction, suggesting that Gekko might be a effective anti-tumor drug.

  • This study was conducted to evaluate the effect of inclusion of propolis extraction residue in the feed of broilers from 1 to 21 d of age on phagocytic activity of macrophages, cutaneous basophil hypersensitivity response to phytohemagglutinin, antibody production against Newcastle disease, lymphoid organ weight and hematological profile and to determine the optimal level of inclusion. 120 chicks, reared in metabolism cages until 21 days of age, were distributed in a completely randomized design, with five treatments (0%, 1%, 2%, 3%, and 4% of propolis residue) and six replications. The relative weight of thymus and monocyte percentage were affected by propolis residue, with a quadratic response (p<0.05) and lowest values estimated at 2.38% and 2.49%, respectively. Changes in relative weight of cloacal bursa and spleen, percentage of lymphocyte, heterophil, basophil, eosinophil, and heterophil:lymphocyte ratio, antibody production against Newcastle disease, phagocytic activity of macrophages and the average number of phagocytosed erythrocytes were not observed. The nitric oxide production with regard to positive control (macrophages+erythrocytes) decreased linearly (p<0.05) with increased doses of propolis residue. The remaining variables of nitric oxide production (negative control - macrophages, and difference between the controls) were not affected by propolis residue. The cutaneous basophil hypersensitivity response to phytohemagglutinin as determined by the increase in interdigital skin thickness exhibited a quadratic response (p<0.05), which predicted a lower reaction response at a dose of 2.60% of propolis residue and highest reaction response after 43.05 hours of phytohemagglutinin injection. The inclusion of 1% to 4% of propolis extraction residue in broiler diets from 1 to 21 days of age was not able to improve the immune parameters, despite the modest changes in the relative weight in thymus, blood monocyte percentage, nitric oxide concentration, and interdigital reaction to phytohemagglutinin.

  • Objective: Defensins are a large family of antimicrobial peptides and components of the innate immune system that invoke an immediate immune response against harmful pathogens. Defensins are classified into alpha-, beta-, and theta-defensins. Avian species only possess beta-defensins (AvBDs), and approximately 14 AvBDs (AvBD1-AvBD14) have been identified in chickens to date. Although substantial information is available on the conservation and phylogenetics, limited information is available on the expression and regulation of AvBD8 in chicken immune tissues and cells. Methods: We examined AvBD8 protein expression in immune tissues of White Leghorn chickens (WL) by immunohistochemistry and quantitative reverse transcription-polymerase chain reaction (RT-qPCR). In addition, we examined AvBD8 expression in chicken T-, B-, macrophage-, and fibroblast-cell lines and its regulation in these cells after lipopolysaccharide (LPS) treatment by immunocytochemistry and RT-qPCR. Results: Our results showed that chicken AvBD8 protein was strongly expressed in the WL intestine and in macrophages. AvBD8 gene expression was highly upregulated in macrophages treated with different LPS concentrations compared with that in T- and B-cell lines in a time-independent manner. Moreover, chicken AvBD8 strongly interacted with other AvBDs and with other antimicrobial peptides as determined by bioinformatics. Conclusion: Our study provides the expression and regulation of chicken AvBD8 protein in immune tissues and cells, which play crucial role in the innate immunity.

  • Several populations of lymphocytes possess receptors for autonomic neurotransmitter, which make lymphocytes susceptible to autonomic stimulation. This study was to evaluate the functional alternation of effector cells of the immune system. Female Balb/C mice, 15-20 g, were injected with MA subcutaneously under various conditions. Mixed lymphocyte reaction (MLR) showed certain T cell subsets were affected by MA. The level of interleukin-2 (IL-2) production was inhibited due to a defect in expression of the IL-2 receptor. In mice injected with 20 mg MA/kg, 1 day before assay, phagocytosis of peritoneal macrophages showed $14.07\pm3%$, which was similar degree to 5 mg MA/kg treatment for 4 consecutive days. Phagocytosis was almost recovered to that of control after 4 day in 20 mg/kg injected mice. Maximum inhibition of plaque forming cell (PFC) occurred when MA was given early, indicating the inductive time point of antibody production was affected. The cortisol level increased in the MA treated group (0.05, 0.20, and $0.08{\mu}g$/dl for control, low, and high dose-MA treated mice, respectively). Based on these results, MA has general suppression effects on the immune systems by functional alteration of effector cells. Considering the increment of serum cortisol levels, MA partially impacts the neuroendocrine system to lead to failure of immune response.
