  • Immune-mediated hemolytic anemia(IMHA) is one of the most common causes of anemia in small animals and immune-mediate thrombocytopenia(IMT) is also an immune mediated disease that affects small animals. The initial treatment for IMHA and IMT is medical suppression of the immune system with glucocorticoids and other immunosuppressive drugs. However, even with appropriate treatments, some animals are not responsive to the treatment and may need further immunosuppressive therapies or some alternative medicines. An eight-year-old spayed female Siamese cat with IMHA and an eight-year-old castrated male King Charles Spaniel dog with IMT were referred to the traditional medical service of the veterinary medical center. Both animals were unresponsive to steroids or other immunosuppressive treatments. Gui-Pi-Tang, one of the traditional herbal medicines, was administered to the animals. After 1-month of Gui-Pi-Tang administration, the packed cell volume(PCV) of the cat and platelets count of the dog had showed remarkable improvement. After four months of follow up in the cat, and 18 months of follow up in the dog, the improved PCV and platelet counts of the animals were maintained normally. Therefore, Gui-Pi-Tang might be considered as an alternative treatment in small animals with immune-mediated blood disorders.

  • Germanium-fortified yeast (GY) is a organic germanium-fortified yeast with potent immune modulating activities including anti-inflammatory effect. Through cell line studies, we observed that GY can modulate the diverse immune activity but little evidence was provided on the mechanism of GY in modulating immune activities in other higher animals. In this study, we investigated the effect of GY on modulation of immune function in mice. GY was administered in normal mice or tumor-bearing mice and then effect of GY on modulation of host immune system was analyzed by using ex vivo isolated macrophages, B cells, NK cells. Admistration of GY in mice induced macrophage activation thereby increased effector function of macrophage such as increased phagocytosis, chemotaxis, adherence, $O_2-release$, NO, $TNF-{\alpha}$ production. In addition, GY administration Increased B lymphocyte activation and plaque forming cells. Furthermore, GY administration increased NK-cell mediated cytotoxicity. Furthermore, GY administration suppressed progression of tumor in mice by increasing $TNF-{\alpha}$ production and effector function of NK cells. Our results showed that GY has a potent immunostimulatory function in vivo mice model. Proper modulation and administration of GY in human could be helpful to maintaining immunological homeostasis by modulating host immune system.

  • Vitamin D is a fat-soluble vitamin helps to retain calcium and phosphorus but also has shown to affect immune regulation and homeostasis. In humans, vitamin D3 and vitamin D2 and their metabolite has intensively studied in both innate and adaptive immune system that they are important to regulate overwhelmed inflammation. The vitamin D receptor is a nuclear hormone receptor which regulate various downstream target gene expressions as a transcription factor related to metabolism, immune regulation, etc. Vitamin D deficiency is a high-risk factor for inflammatory diseases like autoimmune disease and allergy. In addition, reduced vitamin D seem to correlate with susceptibility to the virus infection such as HIV and COVID-19. In this review, we will summarize up-to-date vitamin D's role in various immune cells, immune regulatory functions during autoimmune, allergic, and infectious diseases. We will also discuss about vitamin D supplement effects in human trial studies for COVID-19.

  • Probiotics, specifically Lacticaseibacillus rhamnosus, have garnered attention for their potential health benefits. This study focuses on evaluating the probiotic properties of candidate probiotics L. rhamnosus IDCC 3201 (3201) using the Caenorhabditis elegans surrogate animal model, a well-established in vivo system for studying host-bacteria interactions. The adhesive ability to the host's gastrointestinal tract is a crucial criterion for selecting potential probiotic bacteria. Our findings demonstrated that 3201 exhibits significantly higher adhesive capabilities compared with Escherichia coli OP50 (OP50), a standard laboratory food source for C. elegans and is comparable with the widely recognized probiotic L. rhamnosus GG (LGG). In lifespan assay, 3201 significantly increased the longevity of C. elegans compared with OP50. In addition, preconditioning with 3201 enhanced C. elegans immune response against four different foodborne pathogenic bacteria. To uncover the molecular basis of these effects, transcriptome analysis elucidated that 3201 modulates specific gene expression related to the innate immune response in C. elegans. C-type lectin-related genes and lysozyme-related genes, crucial components of the immune system, showed significant upregulation after feeding 3201 compared with OP50. These results suggested that preconditioning with 3201 may enhance the immune response against pathogens. Metabolome analysis revealed increased levels of fumaric acid and succinic acid, metabolites of the citric acid cycle, in C. elegans fed with 3201 compared with OP50. Furthermore, there was an increase in the levels of lactic acid, a well-known antimicrobial compound. This rise in lactic acid levels may have contributed to the robust defense mechanisms against pathogens. In conclusion, this study demonstrated the probiotic properties of the candidate probiotic L. rhamnosus IDCC 3201 by using multi-omics analysis.

  • Pattern recognition receptors are known to participate in the activation of Prophenoloxidase system. In this study, a 1,3-${\beta}$-D-glucan recognition protein was detected for the first time in Antheraea pernyi larvae (Ap-${\beta}GRP$). Ap-${\beta}GRP$ was purified to 99.9% homogeneity from the hemolymph using traditional chromatographic methods. Ap-${\beta}GRP$ specifically bind 1,3-${\beta}$-D-glucan and yeast, but not E. coli or M. luteus. The 1,3-${\beta}$-D-glucan dependent phenoloxidase (PO) activity of the hemolymph inhibited by anti-Ap-${\beta}GRP$ antibody could be recovered by addition of purified Ap-${\beta}GRP$. These results demonstrate that Ap-${\beta}GRP$ acts as a biosensor of 1,3-${\beta}$-Dglucan to trigger the Prophenoloxidase system. A trace mount of 1,3-${\beta}$-D-glucan or Ap-${\beta}GRP$ alone was unable to trigger the proPO system, but they both did. Ap-${\beta}GRP$ was specifically degraded following the activation of proPO with 1,3-${\beta}$-Dglucan. These results indicate the variation in the amount of Ap-${\beta}GRP$ after specific immune challenge in A. pernyi hemolymph is an important regulation mechanism to immune response.

  • Inflammation is the complex biological response of injured tissues to harmful stimuli. A cascade of biochemical events propagates and matures the inflammatory response, involving the local vascular system, the immune system, and various cells within the injured tissue. The immune system is often involved with inflammatory disorders, demonstrated in both allergic reactions and some myopathies, with many immune system disorders resulting in abnormal inflammation. An Arbitrary Waveform Generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms for the treatment of patients. The patients with gastritis and arthritis have been known to have a relatively favorable prognosis with AWG treatment. Accordingly, we examined the effects of AWG treatment in gastritis and arthritis animal model. The compound 48/80 was used to induce animal gastritis model. The tissue malone dialdehyde (MDA) and serum histamine levels, and the activity of superoxide dismutase (SOD) in stomach tissue were measured. The tissue MDA and serum histamine levels in AWG treated groups exhibited the decreased tendency compared with control group, whereas the tissue SOD activity was slightly increased. The Freund's complete adjuvant was used to induce animal arthritis model as well. The paw edema volume and the width of ankle joint were determined. The AWG treatment significantly decreased the paw edema volume after 5th day of treatment. Although further studies should be performed to confirm the effects of AWG treatment, present study suggest that AWG treatment might be used as a complementary treatment for the gastritis or arthritis treatment.

  • The purpose of this study was to investigate the influences of immune function and respiratory system on aerobic exercise of 75 %HRmax intensity in an exposed acute hypobaric hypoxic environment. The subjects were 20 male college students, 10 of which were soccer players (19.6${\pm}$0.8 yr, BMI 22.3${\pm}$1.0, V02max 56.5${\pm}$4.8 mljkgjmin) and 10 general students (22.2${\pm}$2.3 yr, BMI 22.7${\pm}$2.1, $VO_{2max}$ 50.5${\pm}$6.6 ml/kg/min). Items of measurement after exercise on level and high altitude were $O_{2}$, $CO_{2}$, ventilation (VE), respiratory frequency, respiratory quotient, RBC, MCV, MCH, MCHC, Hb, Hct, reticulocyte, WBC, neutrophil, lymphocyte, monocyte, basophil, and immunoglobulin (IgA, IgD, IgG, IgM). As the result of the verifying hypothesis, these results may suggest three new findings: first, to produce hypoxic ventilatory depression not only at level land but also at 3,000 m high altitude during 30 minute aerobics exercise of 75 %HRmax intensity, second to be more excellent for soccer players in adaptation and sensibility on response of respiratory system at high altitude, and third, to change each other by regular exercise habits or altitude in the monocyte.

  • Objectives : The purpose of this study is to compare atopic dermatitis and food allergy of Korean Medicine with those of western medicine. Methods : We examined the relationship between atopic dermatitis and food allergy mainly in digestive system abnormalities through literature review. Results : Food allergy is classified into categories such as diarrhea, abdominal pain and cough caused by retention of undigested food(食積) and pimples(癮疹) in Korean medicine. The side effects caused by specific immune reactions occur repeatedly due to exposure to specific food allergen or retention of undigested food. Atopic dermatitis and food allergy are often coexisting and deeply related. Digestive system abnormalities can result not only in indigestion but also in immune function abnormalities. Food allergies are known to cause atopic dermatitis and the influx of food antigens exacerbates atopic dermatitis. This corresponds to atopic dermatitis due to abnormal digestive system(脾胃) accompanied by fever(熱), wind(風), and weakness(虛) with focusing on dampness(濕). A typical example of the relationship between atopic dermatitis and food allergy in Korean medicine is Tae-yeul (胎熱). Tae-yeul refers to atopic dermatitis caused by a sensitization to reaction to the dietary antigens of the mother through the placenta during the fetal life with a unusual genetic disposition. Conclusions : We compared korean medicine with western medicine for atopic dermatitis and food allergy. Atopic dermatitis caused by abnormal immune function due to ingestion of food antigen corresponds to dermatitis due to retention of undigested food(食積), digestive system(脾胃臟) problems in korean medicine.

  • It is a recent observation that about 80 per cent of the body's immune system is localized in the gastrointestinal tract. This explains to a large extent why eating right is important for the modulation the immune response and prevention of disease. I addition it is increasingly recognized that the body has an important digestive system also in the lower gastrointestinal tract where numerous important substances are released by microbial enzymes and absorbed. Among these substances are short chain fatty acids, amino acids, various carbohydrates, polyamines, growth factors, coagulation factors, and many thousands of antioxidants, not only traditional vitamins but numerous flavonoids, carotenoids and similar plant- and vegetable produced antioxidants. Also consumption of health-promoting bacteria (probiotics) and vegetable fibres (prebiotics) from numerous sources are known to have strong health-promoting influence. It has been calculated that the intestine harbours about 300 000 genes, which is much more than the calculated about 60000 for the rest of the human body, indicating a till today totally unexpected metabolic activity in this part of the GI tract. There are seemingly several times more active enzymes in the intestine than in the rest of the body, ready to release hundred thousand or more of substances important for our health and well-being. In addition do the microbial cells produce signal molecules similar to cytokines but called bacteriokines and nitric oxide, with provide modulatory effects both on the mucosal cells, the mucosa-associated lymphoid system (MALT) and the rest of the immune system. Identification of various fermentation products, and often referred to as synbiotics, studies of their role in maintaining health and well-being should be a priority issue during the years to come.
