The purpose of this research was to investigate the effect of Kamidangkwieumja(KDEJ) water extract on the allergy reaction in mice. The results were obtained as follows: 1. The passive cutaneous anaphylaxis induced by egg albumin in fat was not affected. 2. The lethal anaphylaxis induced by platelet activating factor in mice. was inhibited. 3. The degranulation of peritoneal mast cells induced by compound 48/80 was not affected. 4. The acute hind paw edema was inhibited after 2hours later when it was induced by histamine. 5. The permeability of evans blue into peritoneal cavity induced by acetic acid was not affected. 6. Arthus reaction in mice was not affected. 7. The delayed type hypersensitivity induced by SRBC was inhibited. 8. The contact dermatitis induced by DNFB was not affected. 9. The hemagglutination titer induced by SRBC was inhibited. 10. The writhing syndrome induced by acetic acid was inhibited. 11. The population of heper T cells in mice thymus was enhanced. 12. The phagocytic activity of peritoneal macrophages was enhanced. 13. The production of nitric oxide from peritoneal macrophages was not affected. These results suggest that the anti-allergy effect of KDEJ is caused by steroidlike and enhanced immune action. The steroidlike action of KDEJ correspond with steroid-applying-method that frequently used in clinic, so it is used io treatment of psoriasis. The research on anti-allergy of KDEJ might has to be continued.

To elucidate pathologic change of skin in porcine exudative epidermitis, immunohistochemical and electron microscopical observations were carried out in the skin of the suckling pigs inoculated with Staphylococcus hyicus subsp hyicus which were isolated from natural case. In immunohistochemistry, ATPase-positive dendritic cells were more populated in epidermo-dermal junctional areas and perivascular area in dermis than in epidermal area as the disease was proceeded. These dendritic cells were identified as Langerhans cell by immunoperoxidase staining and these cells were populated granulomatous bodies. Electron microscopical study showed various retrogressive degeneration and vacuolation of epidermal cell organelles with retention of amorphorous exudates in intercellular space, and cellular seperation. Langerhans cells present in intercellular space of epidermis were populated in epidermo-dermal junctional areas, in dermis, and around granulomatous bodies. Langerhans cells contained decreased Birbeck granules in number but increased lysosome and ribosome. These cells were in contact with lymphocytes. This study was discussed relation between the various immunocytes and the formation of granulomatous bodies, and this inflammation was considered as delayed type hypersensitivity.

Leishmania tropica is one of the causative agents of leishmaniasis in humans. Routes of infection have been reported to be an important variable for some species of Leishmania parasites. The role of this variable is not clear for L. tropica infection. The aim of this study was to explore the effects of route of L. tropica infection on the disease outcome and immunologic parameters in BALB/c mice. Two routes were used; subcutaneous in the footpad and intradermal in the ear. Mice were challenged by Leishmani major, after establishment of the L. tropica infection, to evaluate the level of protective immunity. Immune responses were assayed at week 1 and week 4 after challenge. The subcutaneous route in the footpad in comparison to the intradermal route in the ear induced significantly more protective immunity against L. major challenge, including higher delayed-type hypersensitivity responses, more rapid lesion resolution, lower parasite loads, and lower levels of IL-10. Our data showed that the route of infection in BALB/c model of L. tropica infection is an important variable and should be considered in developing an appropriate experimental model for L. tropica infections.

Purpose: Chlorine gas is a common irritant that usually causes mild respiratory symptoms. One severe symptom, RADS (Reactive Airway Dysfunction Syndrome), is not well known to physicians. We analyzed the clinical features of chlorine gas exposure. Methods: We prospectively collected 25 cases of chlorine gas exposure near our emergency center on January 10th, 2007, and analyzed demographic data, event-to-ER interval, symptoms, and laboratory results based on medical records. Results: Only 2 patients out of 25 were admitted because of severe symptoms, the rest were discharged without complications. Sixty percent of them visited the ER within 12 h of exposure. The most common symptoms were chest discomfort (60%), headache (40%), nausea (40%), throat irritation (26%), and cough (32%). Two out of eight dyspnea cases showed abnormal pulmonary function, but only one case was diagnosed as RADS. Conclusion: Most symptoms after chlorine gas exposure can be treated conservatively. However, patients with chlorine exposure should be followed up long term for delayed complications.

The purpose of this research was to investigate the effects of Kwakhyangjeonggisan (KJS) on the anti-allergic action. In the present study, we examined the effect of KJS on type I and type IV allergic reaction. KJS inhibited the systemic anaphylaxis induced by compound 48/80 and platelet activating factor (PAF), and inhibited the passive cutaneous anaphylaxis (PCA) induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin (HSA) in vivo. In addition, KJS dose-dependently inhibited the release of histamine from peritoneal mast cells in rat. Also, KJS inhibited the delayed type hypersensitivity (DTH) induced by SRBC and the contact dermatitis induced by dinitrofluorobenzene (DNFB). KJS inhibited the proliferation of splenocytes, the subpopulation of B220+ cells and CD4+CD8-(Th) cells in splenocytes and the production of γ-interferon in serum and splenocytes. These findings suggest that KJS prevented the type I allergy by the inhibition of histamine release from mast cells and the type IV allergy by the inhibition of γ-interferon production and B lymphocytes subpopulation. These results indicate that KJS may be useful for the prevention and treatment of type I and type IV allergy related disease.

Amelogenesis Imperfecta (AI) is a genetic disorder which retards the development of enamel and it can be classified into three types: hypoplastic, hypomaturation, hypocalcified type. This can occur both in deciduous and permanent dentition. A 8 year 8 month old patient with a chief complaints of delayed eruption on upper anteriors, calculus deposit on lower anteriors and anterior openbite visited the clinic. Anteriors had thin layer of enamel and were very narrow. Especially lower anteriors had rough surface and were in bad shape. Teeth were very hypersensitive to thermal changes. Upper and lower first molars showed severe attrition on the occlusal surface. Radiographs also verified hypoplastic enamel in the whole dentition including the teeth in the tooth bud. The patient was diagnosed as hypoplastic AI, and is being treated at the pediathc and prosthodontic department of the Kyunghee dental university hospital. To improve the function, esthetics, hypersensitivity of the AI patients, restorations on the posteriors and the anteriors with oral hygiene instruction are necessary, Constant follow-up check is needed until full growth and after full growth, cooperative care with the other department is needed.

This study was designed to investigate the antitumor effect and immunological activities of chitosan extracted from Solenocera prominetis toward on mire bearing sarcoma-180. The growth inhibition ratio of the chitosan toward sarcoma-180 showed at the highest level of 63.84% when chitosan were administrated at the concentration of 40mg/kg. The direct cytotoxic effect of chitosan was not observed in the mice bearing sar-roma-180 in vitro. In the effect of immunological activities, dose-dependent responses indicated by the increase of leucocyte, peritoneal exudate cell than that of control group when chitosan administered to the mice in the concentation of 30mg/kg and 40mg/kg. Also dose-dependent responses showed also by the increase of immunoorgans weights such as body weight, liver, spleen or thymus in the same concentration of 30mg/kg and 40mg/kg. Food pad swelling having the relationship with arthus reaction of antibody-mediated hypersensitivity and delayed type hypersensitivity was recovered the almost normal level. In the efforts of macrophge on phagocytes, there were not substantial differences in phagorytic and corrected phagocytic index. In the number of plaque forming cell(PFC), PFC on the 10$^{7}$ spleen cells were increased the levels of 18.88% and 31.83% when chitosan were adminstersd at the concentration of 30mg/kg and 40mg/kg.

This study was undertaken to assess the susceptibility of pigmented and nonpigmented strains of Serratia marcescens to antibiotics and human sera, and the effect of culture filtrates from pigmented and nonpigmented of Serratia marcescens on humoral and cellular immune responses in mice to thymus-dependent and indepependent antigens. Humoral immune response was measured by hemagglutinin (HA) and hemolysin (HE) to sheep red blood cell (SRBC), and Arthus or antibody response to polyvinylpyrrolidone (PVP). The cellular immune response was measured by delayed-type hypersensitivity (DTH) determined by footpad swelling reactin to SRBC. The resistance of pigmented strains of Serratia marcescens to the bactericidal action of heat inactivated human serum was insignificantly greater than that of nonpigmented strains. However, the pigmented strains were significantly more resistant to the bactericidal action of heat-untreated human serum than that of nonpigmented strains. The clinical isolates of Serratia marcestens was also tested for their resistance to several antibiotics. There was no difference between the pigmented and non-pigmented strains in the resistance to carbenicillin. However, nonpigmented strains were more resistant to gentamicin, kanamycin and tobramycin than the pigmented strains. The intraperitoneal administration of culture filtrates from the pigmented or nonpigmented strains into mice caused enhancemented of antibody response to SRBC or PVP, and of DTH to SRBC. Besides, their enhancement of immune responses was more prominent when culture filtrate from the pigmented strains was administered.

Effects of varied dietary energy densities on immune response and performance of Muzzafarnagari lambs were ascertained in a 180-d study. Animals (n = 24), in three groups, were fed diets providing 100% (100E), 80% (80E) or 70% (70E) of their metabolizable energy requirement. Mean nutrient digestibilities varied significantly among treatments. Nitrogen intake was lower (p<0.01) in the 70E. Nitrogen retention, was reduced (p<0.001) in 80E and 70E vs 100E. The average daily gain (p<0.001) was $47.01{\pm}4.23$, $13.54{\pm}1.72$ and $-16.67{\pm}8.24$ g for 100E, 80E and 70E, respectively. Hemoglobin concentration, haematocrit, total and differential leukocyte counts were lower (p<0.001) for 80E and 70E than for 100E with a similar trend (p<0.05) for serum glucose and total protein. Serum cortisol was reduced (p<0.001) with decreased energy availability. Antibody titre to Brucella abortus S19 showed an initial reduction in 80E and 70E vs 100E. Delayed-type hypersensitivity response was lower (p<0.001) in 80E and 70E vs 100E, accompanying a lower (p<0.001) nitric oxide production by the peripheral lymphocytes. It is concluded that the reduced dietary energy density significantly affects the growth performance and immune response of lambs.

Lipopolysaccharide binding protein (LBP) and CD14 protein play important roles in the defense against infection of Gram-negative bacteria. In the present study, tissue distribution and polymorphism of porcine LBP and CD14 genes were analyzed. Real-time PCR results showed that the porcine LBP gene was especially highly expressed in liver, while CD14 gene was highly expressed in liver and spleen tissues. A 1,732 bp cDNA fragment of porcine LBP gene and a 1,682 bp genomic DNA fragment of CD14 gene were isolated. Polymorphisms were identified in these two fragments and showed that there were 14 potential SNPs in the porcine LBP gene and 3 potential SNPs in the porcine CD14 gene. Three SNPs, 292G/A (Gly/Ser), 1168G/A (Ala/Thr) of the LBP gene and -61G/A of the CD14 gene, were genotyped using restriction fragment length polymorphism (RFLP) method. Association analyses indicated that polymorphism of the 292G/A locus was significantly associated with porcine immune traits hematocrit (HCT), IgG and delayed-type hypersensitivity (DTH) (p<0.01), and the 1168G/A locus was significantly associated with HCT and mean corpuscular volume (MCV) traits (p<0.05). No significant association was found between the -61G/A locus and immune traits of the pig. Our data indicated that the LBP gene was significantly associated with immune traits of pig. Also, we identified some SNPs which may be useful markers for disease-resistant breeding of pigs.
