  • The gastric endocrine cells of the Korean hedgehog, Erinaceus korean us were studied immunohistochemically. Seven kinds of endocrine cells-, gastrin-, somatostatin-, 5-HT-, glucagon-, BPP-, motiIin-and GIP-immunoreactive cells- were identified in this study. The chracteristic findings of the regional distribution and relative frequency of them were examined. Gastrin-immunoreactive cells were very numerously detected only in the pyloric region. Somatostatin-immunoreactive cells were more numerous in the pyloric region than in the cardiac and fundic regions. 5-HT-immunoreactive cells were more numerous in the cardiac and pyloric regions than in the tundic one. Glucagon-immunoreactive cells were found few or rarely in the fundic and pyloric regions. BPP-imunoreactive cells were numerously distributed in the pyloric region, moderately in the fundic region and few in the cardiac region. Motilin-immunoreactive cells were found rarely or few in the fundic and pyloric regions. GIP-immnuoreactive Cells were detected onIy in the pyloric region.

  • The regional distribution and relative frequencies of the gastro-entero-pancreatic endocrine cells were studied immunohistochemically in the GIT and pancreas of the Korean mole. Seven kinds of endocrine cells were identified in this study. Although 5-HT- and somatostatin-immunoreactive cells were seen throughout the GIT, they were most predominant in the pyloric gland region. Glucagon-immunoreactive cells were restricted on the large intestine. Bovine CG-immunoreactive cells were more frequent in the stomach than in the intestines which were not detected in the duodenum. Numerous Gas/CCK-immunoreactive cells were found in the pyloric gland region, but rarely in the jejunum and ileum. BPP-immunoreactive cells were observed to be rare in the stomach and ileum but were a few in number in the intestines. In the pancreas, four types, namely, glucagon-, somatostatin-, BPP- and insulin-immunoreactive cells were identified in the pancreatic islets and exocrine portion. These results suggest that although endocrine cells of the Korean mole is less abundant in the duodenum, the distribution pattern of its gastro-entero-pancreatic endocrine cells is similar to that reported for the Korean hedgehog.

  • The regional distribution and the relative frequencies of endocrine cells were studied in nine portions of the blue fox GI tract, and the distribution pattern and cell types of the pancreativc endocrine cells were also studied in the pancreas by immunohistochemical method. Six kinds of immunoreactive cells were identified in the GI tract, and four kinds of immunoreactive cells were also identified in the pancreas. Although numerous 5-HT- and somatostatin-immunoreactive cells were seen throughout the GI tract, somatostatin- immunoreactive cells were a few in the intestine. Very numerous Gas/CCK-immunoreactive cells were restricted generally in the pyloric region and duodenum. Numerous glucagon-immunoreactive cells were found in the stomach except the pyloric region, and generally a few in the intestine. Moderate number of BPP-immunoreactive cells were found in the stomach except the pyloric region, and a few in the large intestine. Numerous porcine CG-immunoreactive cells were restricted to the cardiac and fundic region. In the pancreas, four types of pancreatic endocrine cells- somatostatin-, glucagon-, BPP- and insulin-immunoreactive- were identified in the pancreatic islet and exocrine portion. These results suggest that the regional distribution, the relative frequencies and cell types of the GEP endocrine cells in the GI tract and pancreas varies considerably among the species.

  • Immune system provides defense integrity of body against external invaders. In order to accomplish the important defending role immune system is composed of many different components which are regenerated continuously during lifespan. The key components are professional killing cells such as macrophage, neutrophil, natural killer cell, and cytotoxic T cell and professional blocking molecule, antibody, which is produced by plasma cell, the terminal differentiated B cell. Immune response is orchestrated harmoniously by all these components mediated through antigen presenting cells such as dendritic cells. Immune responses can be divided into two ways: innate immune response and adaptive immune response depending on induction mechanism. Aging is a broad spectrum of physiological changes. Likewise other physiological changes, the immune components and responses are wane as aging is progressing. Immune responses become decline and dysregulating, which is called immunosenescense. Immune components of both innate and adaptive immune response are affected as aging progresses leading to increased vulnerability to infectious diseases. Numbers of immune cells and amounts of soluble immune factors were decreased in aged animal models and human and also functional and structural alterations in immune system were reduced and declined. Cellular intrinsic changes were discovered as well. Recent researches focusing on aging have been enormously growing. Many advanced tools were developed to bisect aging process in multi-directions including immune system area. This review will provide a broad overview of aging-associated changes of key components of immunity.

  • This present study demonstrates the immunological synergistic effects of herbal preparation (HemoHIM) and red ginseng powder granule in various immune cell models (bone marrow-derived macrophages, dendritic cells, and mouse splenocytes) from mice. Both herbal preparation and red ginseng extracts were treated to bone-marrow derived macrophages, dendritic cells, and mouse splenocytes, and there was no cytotoxicity at a dose below $200{\mu}g/mL$. Cell proliferation and cytokine [tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, and IL-12] production tested in bone marrow-derived macrophages and dendritic cells significantly increased upon combined treatment. Cell surface marker (CD 80/86, MHC class I/II)-mediated immune cell activation was highly elevated by combined treatment. For cytokine production in splenocytes, combined treatment significantly increased production of Th 1 type cytokines [IL-2 and interferon (IFN)-${\gamma}$] but not Th 2 type cytokines (IL-4 and IL-10). Therefore, combined treatment with HemoHIM and red ginseng extracts is an effective method to establish powerful immunological synergy in immune cells.

  • In order to determine the functional benefits of $Cordyceps$ $militaris$ in the immune system, we examined the immunomodulatory activities of $Cordyceps$ $militaris$ in an immunocompromised C57BL/6 mice model. Mice were injected intraperitoneally with an immunosuppressive drug, cyclophosphamide, and then administered orally with 3% hydroxypropylmethylcellulose or 30, 100, and 300 mg/kg of 50% ethanol extract of $Cordyceps$ $militaris$ (CM 30, CM 100, and CM 300, respectively) for 12 days. Mice treated with CM displayed significantly increased splenocyte proliferation and natural killer cell activity compared to immunosuppressed control mice (p<0.05). The spleen cells isolated from mice treated with CM also displayed increased production of Th1 cytokines, including IL-2, IL-12, IFN-${\gamma}$ and TNF-${\alpha}$, suggesting enhanced cellular immunity in response to CM. However, CM had no significant effect on the production of IL-4 and IL-10. These results indicate that $Cordyceps$ $militaris$ enhances immune function by promoting immune cell proliferation and Th1 cytokine production.

  • In this study, the effect of the polychaete antimicrobial peptide as feed additives on fish, olive flounder (Paralichythys olivaceus) and black rockfish (Sebastes schlegelii), immune activity was described. The antimicrobial peptide of the polychaete was induced by peptidoglycan from Micrococcus luteus. The fish were fed an experimental diet supplemented with 0%, 0.05%, 0.1%, 0.5% or 1% of immune induced the polychaete to a commercial diet. Haematological parameters, nonspecific immunes and stress were evaluated 2, 4, 6 and 8 weeks during fed. The resistance against bacteria, Edwardsiella tarda and Streptococcus iniae, were analysed on after 8 weeks. The haematological parameters were not significantly changed among tested groups. But the lysozyme activities were significantly high in the 0.1% and 0.5% supplement group of olive flounder and black rockfish, respectively. Additionally, cortisol in plasma was low in the 0.1% and 0.5% supplement group of olive flounder and black rockfish, respectively. And resistance of these supplement groups were significantly induced against bacterial injection.
