Purpose : Kawasaki disease(KD) is a multisystemic inflammatory vasculitis of unknown etiology. Many complications other than cardiovascular involvement have been recognized in KD. However, there have been few reports published concerning involvement of the lungs in this disease. The purpose of this study was to examine the relationship between serum TNF-${\alpha}$, the degree of coronary artery dilatation and chest X-ray(CXR) findings. In addition, we have investigated serum anti-Mycoplasma antibody(AMA) titers in patients with KD who have abnormal CXR findings. Methods : Eighty four patients with KD were included in this study(group I; 41 patients with normal CXR fndings, group II; 43 patients with abnormal CXR findings). Serum levels of TNF-${\alpha}$ and AMA titer were measured. Results : We reviewed the CXR findings and clinical courses of 84 patients with Kawasaki disease and found abnormal CXR findings in 43 patients(51.2 percent). Peribronchial cuffing was the most frequent abnormality(22.4 percent). In the group with abnormal CXR findings(group II), a statistical difference was not noted in age, sex, duration of fever, hemoglobin, WBC, platelet, ESR, and CRP levels and incidence of coronary arterial lesions as compared with the group having normal CXR findings(group I). No difference was noted in serum TNF-${\alpha}$ level between group I and group II. 2 patients(12.5 percent) of 16 KD patients with abnormal CXR findings have positive AMA titer(above 1 : 320). Conclusion : Most of the abnormal CXR findings in KD patients were peribronchial cuffing. The abnormal CXR findings in KD patients did not mean severe inflammations. It is difficult to consider that CXR abnormalities are related to coronary arterial lesions. In addition, further study on the relationship between Mycoplasma infection and Kawasaki disease is needed.
This experiment was carried out to investigate the combination feeding of β-glucan and multi-species probiotics on growth performance, various lipid concentrations of serum, antibody production and cecal microbial profiles in broiler chicks. A total of six hundred 1-d-old male broiler chicks were divided into five groups, placed into four pens per group(30 birds per pen) and fed one of five non-medicated experimental diets(T1, 0.15% multi-species probiotics; T2, 0.1% β-glucan+0.15% multi-species probiotics; T3, 0.3% multi-species probiotics; T4, 0.1% β-glucan+0.3% probiotics or devoid them as control) for 5 wk. There was no significant difference in feed intake among the groups. The average weight gains and FCR in groups fed diet containing 0.3% probiotics were significantly improved(p<0.05) than control in finisher period(22-35d). The concentration of serum cholesterol ester in groups fed 0.3% probiotics were significantly lowered(p<0.05) as compared to that of the control. Relative weights of liver, spleen, bursa of Fabricius, breast and leg were not influenced by the dietary treatments. The average ND or IB antibody titers in groups fed diets containing β-glucan and probiotics were tended to be increased, but not significantly. The number of cecal lactic acid bacteria was significantly increased(p<0.05) by the dietary β- glucan and probiotics. These results indicated that dietary β-glucan and probiotics exerted a growth- promoting and immune-enhancing effects on broiler chicks. In addition, yeast derived β-glucan, and multi-species probiotics modulated the profiles of cecal microflora, reflecting potential alternative substances to replace antibiotics for feeding broiler.
During the period from 1956 to 1959, a serological survey was conducted in au effort to assessing the incidence of brucellosis in various domestic animals in Korea. The following results were obtained. 1. Seventy-six dairy cattle which were imported in the year of 1956 had 9 positive reactors (11.84%). Of 1127 goats imported in 1956 and 1958, eleven(0.98%) were reactor animals. 2. In 1956, of 108 dairy cattle tested 10(9.25%) were reactors. In 1937 and 1958, a total of 155 dairy cattle examined hid ten (6.45%) positive reactors. In 1959, of 127 dairy cattle examined two were reactor animals. 3. In 1958 and 1959, 432 goats in some districts in Korea were subject to test for brucellosis and the test revealed five (1.15%) reactors. In 1958, 683 swine serum samples were examined and eleven (1.04%) were positive. In 1959, 1133 Korean cattle were tested and seven samples (0.64%) showed positive reactions. 4. In the month of July in 1939, 580 beef cattle in Cheju National Ranch and Branch were examined and 111 (19.13%) were found to be reactors. In October of the same year, 157 cattle, consisting of reactor and suspicious cattle groups, were tested, of which 71 samples reacted positive and 47 remained suspicious. 5. In December of the year of 1958, there occurred. an outbreak of brucellosis in a swine herd in the Sachon Branch Experimental Station. Seven serological tests on 438 swine serum samples were conducted, of which 122 (27.87%) were found positive. 6. Dairy cattle No. 33 and No. 35 which had been imported in 1956 and detected as highly positive, were examined for a prolonged period to follow the variation of antibody titers. A marked drop in antibody titer was seen two months after the initial test while the re-increase in titer was observer our months after the first examination.
This experiment was conducted to investigate the effects of dietary enzyme mixture fortified with ${\beta}-glucanase$ on the growth performance, serum components and meat quality of broiler chicks. 31,800 Ross 208 male broiler chicks were randomly allotted into 2 groups, the control and 0.3% enzyme diet with ${\beta}-glucanase$ supplementation groups. Control group chicks were fed the control (corn-soybean meal based) diet and the treatment group chicks were fed the 0.3% enzyme mixture supplemented with ${\beta}-glucanase$. The growth performance, serum components and meat qualities such as pH, color, water holding capacity, cooking loss, and shearing force of meats were investigated. The results showed that the growth performance of chicks fed the 0.3% enzyme mixture diet were improved compared to that of the control group, as much as 5% in growth rate, 19% in average weight, 6.8% in performance index, and 5.5% in feed efficiency. Although, there were no significant differences in the muscle color degrees ($L^*a^*b^*$) and shearing force between the control group and experimental group, the water holding capacity and cooking loss of the experimental group were significantly higher than those of control group (p<0.05). The antibody titers in serum against the antigens of Newcastle disease and Infectious Bursal disease were higher in the experimental group than in the control group. Altogether, these suggest that the broiler diet containing 0.3% enzyme mixture fortified with ${\beta}-glucanase$ activity can improve the growth performance, immune reaction, and meat quality of broiler chicks.
Objective: The aim of this study was to investigate the reversibility and safety of KISS1 metastasis suppressor (KISS1) gene vaccine in immunocastration. Methods: Six eight-week old ram lambs were randomly divided into vaccinated and control groups. The vaccine (1 mg/ram lamb) was injected at weeks 0, 3, and 6 of the study. Blood samples were collected from the jugular vein before primary immunization and at weeks 2, 4, 6, 10, 14, 22, and 30 after primary immunization. All ram lambs were slaughtered at 38 weeks of age, and samples were collected. Results: The specific anti-KISS1 antibody titers in vaccinated animals were significantly higher and the serum testosterone level was significantly lower than those in the control groups from week 4 to 14 after primary immunization (p<0.05). No significant difference was observed at weeks 22 and 30 after the primary immunization. Similar results were also found for scrotal circumference, testicular weight, length, breadth, and spermatogenesis in seminiferous tubules in week 30 after primary immunization. KS (KISS1-hepatitis B surface antigen S) fusion fragment of KISS1 gene vaccine was not detected in host cell genomic DNA of 9 tissues of the vaccinated ram lambs by polymerase chain reaction. Conclusion: The effects of KISS1 gene vaccine in immunocastration were reversible and no integration events were recorded.
Mastoparan V1 was used as adjuvant of formalin-inactivated Salmonella Gallinarum whole cells vaccine against fowl typhoid in a chicken model. The 75 brown nick chickens were equally divided into 5 groups, and all chickens of each group were immunized at 6 weeks of age (0 WPPI; weeks prime post immunization), and at 9 weeks of age (3 WPPI) (except group B). Group A chickens were intramuscularly (IM) inoculated with 500 uL of sterile phosphate-buffered saline (PBS), and group B chickens were subcutaneously immunized with 0.2 ml containing 5×107 viable vaccine strain/bird. The chickens in groups C~E were IM inoculated with approximately 3×109 cells/0.5 mL of formalin-inactivated the S. Gallinarum whole cells, approximately 3×109 cells/0.5 mL of formalin-inactivated the S. Gallinarum whole cells with mastoparan V1 as adjuvant, and 0.5 mL of PBS, respectively. S. Gallinarum outer membrane proteins-specific serum IgG titers were considerably higher in groups B~D than in groups A and E. However, the levels of IFN-γ in groups B and D only than in groups A and E were significantly higher. Following oral challenge with virulent wild-type S. Gallinarum, no chicken in groups A (no challenge group) and B was dead, and only 30% of chickens in group D was dead. However, 70% of chickens in group C and all chickens in group E were dead after oral challenge. The results of this study demonstrated that IM immunization with approximately 3×109 of the formalin-inactivated S. Gallinarum whole cells containing mastoparan V1 induced robust antibody and cell-mediated immune responses in chickens. The whole cells also conferred protection against infection with wild-type S. Gallinarum.

A systematic study was conducted to identify and isolate a serologically pertinent antigen with high specific activity and low cross reactivity from Cysticercus parenchymal antigen. Differential centrifugation of the homogenate yield three particulate and one soluble fractions ; the $480{\times}G$ pellets($CyL_2$), the $7650{\times}G$ pellet($CyL_3$), the $100000{\times}G$ pellet($CyL_4$), and $100000{\times}G$ supernatant($CyL_6$). We compared antigenicity of these antigens to that or cystic fluid antigens($CyF_1$), saline extract of cystic wall($CyL_1$), and n-butanol treated $GyL_4$ antigen ($CyL_6$) based on SDS-PAGE and immunoblot techniques. The data obtained were as follows : 1) The ratio of O.D. value of ELISA against cysticercosis positive pool sera to that of negative pool sera was highest when using $CyF_1$ as antigen. However the ratio was relatively low in case of $CyL_{3.4}$ and $CyL_5$. 2) We have noted in previous paper that most strong antigenic activities are present in 63Kd band with low cross reactivities. An effective serologic reagent must contain components that are recognized by most infected sera. 63Kd band met this criteria and could be considered as a reliable band for the diagnosis of cysticercosis. As far as 63Kd band concern, $CyL_5$ showed most strong activities without disturbance of cross reaction by EITB in spite of low applicability to microplate ELISA. 3) $CyL_5$ could detect the serum antibody of cysticercosis even in very low titers, around cut-off values of microplate ELISA, by immunoblot. It also could detect the cross reactivities of Echinococcus species, which showed high absorbance value in micro plate ELISA and some sparganosis cases. Further purification of this antigen will be able to represents a antigen that can be used in the diagnosis of cysticercosis.
The role of passive cell-mediated transfer of immunity against primary amoebic meningoen- cephalitis(PAME) in mice was studied. Waegleria fowleri, ITMAP 359, were cultured in CGVS medium. The ICR mice used were six week-old males of average weight of 15 g. Immunization was done by three intraperitoneal injections of $1{\times}10^6$ N. fowleri trophozoites at the interval of one week. Splenocytes were obtained from normal and immune mice spleens, and Ix107 cells were administered intraperitoneally into mice 3 days before challenge infection. Mice were infected intranasally with $7{\times}10^4$ N. fowleri trophozoites in a $3{\;}{\mu}l$ suspension under secobarbiturate anesthesia. Transplants of normal or immune splenocytes seem to alter the pattern of the PAME level- opment. The splenocytcs transferred from immune mice reduced the mortality rate in the JV. fowleri infected mice, as compared with the mice transferred with the same number of normal splenocytes or without splenocyte, The blastogenic response of the splenocytes to both lipopoly- saccharide and concanavalin A was elevated on duty 7 after infection the mice transinoculated with immune splenocytes. The serum antibody titers in the mice transferred with immune spleno- cytes were increased gradually from day 7 up to day 20 after infections by mean of ELISA. It is suggested that the transfer of splenocytes from immuniged mice conferred immunity against N. fowleri infection.
This study was performed to evaluate the prophylactic effects of trimethoprim- sulfamethoxazole (TMP-SMZ) In mice experimentally infected with virulent RH strain and avirulent Beverley strain of T dognii. The mice infected with $1{\times}10^5$ tachyzoltes were used In the measurement of mean survival days, and the mice infected with 10 cysts were used In the tltratlons of specific antibodies and enumeration of brawn cysts. Mean survival days of mice were significantly increased In mice treated with TMP-SMZ as compared with splramycln-treated and untreated control group. Mean survival days and survival rates of mice were Increased according to the Increment of dosages, and TMP-SMZ protected 100% of mice after fifteen daily dose of 24 mg/mouse or more admlnlsted orally. Toxoplasma-specific serum IgG and IgM antibody titers were slgnlflcantly lower in mice treated with TMP-SMZ than those of splramycln-treated and untreated control group. Toxoplosma cysts were not found In mice treated with TMP-SMZ at a dose of 24 mg/mouse or more per day but the group of splramycin treatment and untreated controls were found in the brain from 20 days after Infection. The present results revealed that TMP-SMZ can be used as a prophylactic agent against murine toxoplasmosls after Intraperitoneally challenges with the virulent or avlrulent strain of T. gondii.
Purpose : There have been some reports on the prevalence of positive antineutrophil cytoplasmic antibody(ANCA) in Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP), but the results were conflicting. We performed this study to evaluate the clinical significance of ANCA(c-ANCA and p-ANCA) in Korean children with HSP. Methods : The medical records of 30 patients(13 boys and 17 girls) aged 6.0$\pm$1.9(5-12) years with a clinical diagnosis of HSP based on the EULAR/PReS criteria were reviewed retrospectively. From the years 2007 to 2008, the sera from children with acute HSP were tested for antineutrophil cytoplasmic antibodies(ANCA). The target antigens of these autoantibodies are proteinase 3(c-ANCA) or myeloperoxidase(p-ANCA). Results : Palpable purpura was seen in all 30 patients(100%), abdominal pain in 20(67%), arthralgia in 17(57%), and renal involvement in 11(37%). Laboratory findings showed leukocytosis in 4 patients(13%), thrombocytosis 18 in(60%), and elevated erythrocyte sedimentation rate in 18(60%). Anti-streptolysin O titers were elevated in 7% of the patients and no patient showed elevation of serum IgA level. The sera from 29 patients were negative for c-ANCA and p-ANCA by indirect immunofluorescence, but only one patient had weakly positive results, which became negative at follow-up. Conclusions : We conclude that c-ANCA or p-ANCA is not an important serologic marker in children with HSP, because it was neither diagnostically nor immunologically specific in children with HSP. These results suggest that ANCA are not involved in the pathogenesis of HSP in children.
