  • L-theanine was examined for its effects on the generation of superoxide anion, lysozyme and anti-protease in the plasma of catfish (Silurus asotus) by a single intraperitoneal injection with five different concentrations (0, 3, 6, 9 and 12 mg/kg). When compared with the mock-injected group (0 mg/kg), both groups injected with 6 and 9 mg/kg were significantly enhanced in levels of superoxide anion in leukocytes, lysozyme and anti-protease in plasma. Based on the results, L-theanine is thought to function as an immunostimulant and/or immunomodulator on non-specific immune responses in catfish.

  • To investigated the effects of Kwibi-tang water extract (KBT) on the non-specific immune response in C57BL/6 mice stressed by immobilization, we evaluated the changes in the contents of serum histamine and corticosterone and the phagocytic activity of macrophages. The level of serum histamine and corticosterone was determined with spectrofluorometer. The cell viability was determined by a MTT assay method. The subpolpulation of lymphocytes was determined by a flow cytometry. The phagocytic activity was determined with luminometer. KBT decreased the serum level of histamine and corticosterone increased by immobilization stress. Also, KBT enhanced the phagocytic activity and decreased the level of nitric oxde in murine peritoneal macrophages decreased by immobilization stress. These results indicate that KBT may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of the non-specific immune response.

  • Nine dogs with history of lameness and anorexia were presented. On physical examination, all dogs had gait abnormality and six dogs had high body temperature. Their clinical signs were mostly episodic, and only non-specific symptoms were occasionally observed. Arthrocentesis was performed in all dogs, and immune-mediated polyarthritis (IMPA) was diagnosed. Definitive rheumatoid arthritis (RA) and systemic lupus erythematous (SLE) were diagnosed in one dogs, one each. Prednisolone (PDS) was chosen as the first-line therapy for all dogs, except for the one with RA. Most cases responded to PDS but some cases including those of SLE and RA were refractory to PDS. IMPA can be challenging to diagnose due to its vague symptom and is commonly implicated in 'fever of unknown origin'. Therefore, clinicians should consider IMPA as a differential diagnosis when the patient has fever with systemic, non-specific signs, such as anorexia and depression, but does not respond to antibiotics.

  • It has been reported that various anti-oxidant substances stimulate non-specific immune responses in fishes. In this study it was examined whether N-acetylcysteine (NAC), an anti-oxidant glutathione (GSH) precursor, can modulate non-specific immune parameters in 8 different fishes. NAC was intraperitoneally administered at 10 mg/kg to catfish (Silurus asotus), loach (Misgurnus mizolepis), common carp (Cyprinus carpio), crucian carp (Carassius carassius), eel (Anguilla japonica), snakehead (Channa argus), tilapia (Oreochromis niloticus) and mullet (Mugil cephalus). Forty-eight hours later, chemiluminescence (CL) response of head-kidney leukocytes and serum lysozyme activity were assessed. In all fishes except crusian carp and loach, CL responses were amplified by NAC. Lysozyme activity was increased by NAC in all fish species but not in tilapia. This result suggests that NAC stimulates non-specific immune responses in various species, and that such effects may have beneficial significance in aquaculture for practical utilization.

  • We examined the effects of Prunella vulgaris Labiatae (P. vulgaris L.) on specific and non-specific immune responses of Nile tilapia, Oreochromis niloticus. The optimal concentration without toxicity of P. vulgaris was determined to $30-40{\mu}g/ml$ in vitro and $120{\mu}g$/100 g of fish in vivo. P. vulgaris significantly elicited an antibody titer compared to FCA or ${\beta}$-glucan. ${\beta}$-glucan plus P. vulgaris group synergistically enhanced antibody production. No significant difference in antibody production was observed between P. vulgaris and P. vulgaris plus ${\beta}$-glucan group. A respiratory burst activity of head kidney (HK) leucocytes of tilapia administered with 300 or $500{\mu}g$ P. vulgaris was significantly (p < 0.05) enhanced compared with the PBS-injected control group and FCA-treated group. Maximum increase in the NBT reduction value was observed in $500{\mu}g$ P. vulgaris group but no significant difference was found between 300 and $500{\mu}g$ P. vulgaris group. The level of serum lysozyme activity was significantly (p < 0.05) higher in the 300 and $500{\mu}g$ P. vulgaris than $100{\mu}g$ P. vulgaris and FCA group. The phagocytic activities of HK leucocytes from tilapia administered with 300 and $500{\mu}g$ P. vulgaris were significantly (p < 0.05) higher than $100{\mu}g$ P. vulgaris and the control group. P. vulgaris was revealed with a good immunoadjuvant evoking the specific and non-specific immune responses of tilapia.

  • A literature study on oncological immune therapy was done, and the results were as follows. 1. Oncological immune therapy is classified as specific non specific therapy or active inactive therapy, and in tumor immune response, cellular immunity operates mainly, so activity of T lymphocytes and macrophages are closely related with growth, progress, metastasis and prospect of tumor. Recently, Immune therapies of gene which use cytokines and HLA-B7 are carrying out. 2. In oriental medicine, development of disease is closely related to up and down of healthy qi, so healthy qi operates as a immune factor and resistance factor. 3. On the base of theory "Increasing healthy qi reduces mass(養正則積自除)", strengthening body resistance is emphasized in cancer therapy. Also strengthening body resistance activates cellular immune response and promote killing tumor facility of T-cell. 4. In clinical view, using immune therapy after operation, radiation, and chemotheraphy is more effective than immune therapy itself, so it is expected that east-west cooperation will be effective in cancer therapy. 5. The study of oncological immunity is progressed on emphasizing T-cell and it is related to oriental medical theory "strengthening healthy qi to eliminate pathogen(扶定祛邪)" and advanced study is expected in future.

  • Juvenile black sea bream, Acanthopagrus schlegelii, were exposed to waterborne zinc (Zn) at concentrations of 0, 200, and $400{\mu}g/L$, at temperatures of 18 or $26^{\circ}C$ for 4 weeks. Superoxide dismutase (SOD) activities in the liver and gill of A. schlegelii significantly increased following exposure to waterborne Zn. Significant reduction in glutathione S-transferase (GST) activity in the liver and gill was observed following exposure to waterborne Zn. Glutathione (GSH) concentrations in the liver and gill also significantly decreased following exposure to waterborne Zn. Phagocytosis and lysozyme in the plasma and kidney were significantly increased following exposure to waterborne Zn. High water temperature increased alterations in the antioxidant and immune responses. The results of the present study suggest that waterborne Zn induced significant alterations in oxidative stress, increased immune responses and high temperature that trigger Zn toxicity.

  • Two feeding trials were conducted to determine the effects of dietary supplementation with Hizikia fusiformis or Ecklonia cava on the non-specific immune responses of parrot fish Oplegnathus fasciatus. Fish were fed experimental diets to which H. fusiformis or E. cava powder were added to final concentrations of 0, 2, 4 and 6%, respectively. After feeding for two weeks, phagocytic activity was significantly higher in fish fed diets containing H. fusiformis, but not E. cava, than in fish fed the basal diet. Lysozyme activity was significantly increased in the fish fed diets containing 6% H. fusiformis and E. cava. Myeloperoxidase activity was also significantly higher in fish fed diets containing 2 and 4% H. fusiformis, as compared to the basal diet, but not in those fish fed E. cava. These two studies indicate that dietary supplementation with H. fusiformis or E. cava could enhance the innate immune responses of parrot fish during their growth stage.

  • The present study examined the effects of dietary supplementation with nucleotide (inosine monophosphate product, IMP) on the growth performance, feed utilization, and non-specific immune responses of juvenile tilapia Oreochromis niloticus. Triplicate groups of tilapia (initial body weight, $7.4{\pm}0.04$ g) were fed experimental diets containing 0%, 0.05%, 0.1%, and 0.2% IMP. Fish were fed six times a day until apparent satiation for 13 weeks. At the end of the feeding trial, final body weight and food utilization of fish fed 0.1% IMP were significantly higher than those of fish fed the control diet. Results of hematological parameters were not affected by dietary IMP. However, blood protein level was significantly higher in the 0.05% treatment, as compared to that of the control and 0.2% IMP diets. Myeloperoxidase activity was higher in fish fed 0.1% IMP than in fish fed the control and 0.2% IMP diets. These results suggest that dietary supplementation with IMP can enhance the growth performance, feed utilization, and innate immune response of juvenile tilapia. The optimal IMP supplementation level appears to be 0.1% in practical feed formulations for tilapia.

  • Clinical and preclinical in vivo immune cell imaging approaches have been used to study immune cell proliferation, apoptosis and interaction at the microscopic (intra-vital imaging) and macroscopic (whole-body imaging) level by use of ex vivo or in vivo labeling method. A series of imaging techniques ranging from non-radiation based techniques such as optical imaging, MRI, and ultrasound to radiation based CT/nuclear imaging can be used for in vivo immune cell tracking. These imaging modalities highlight the intrinsic behavior of different immune cell populations in physiological context. Fluorescent, radioactive or paramagnetic probes can be used in direct labeling protocols to monitor the specific cell population. Reporter genes can also be used for genetic, indirect labeling protocols to track the fate of a given cell subpopulation in vivo. In this review, we summarized several methods dealing with dendritic cell, macrophage, and T lymphocyte specifically labeled for different macroscopic whole-body imaging techniques both for the study of their physiological function and in the context of immunotherapy to exploit imaging-derived information and immune-based treatments.
