  • IgY (egg yolk immunoglobulin) against Helicobacter pylori was produced by immunizing hen with some Helicobacter pylori antigens. H. pylori whole cell, whole cell lysates, partially purified urease and p54 protein, which showed high antigenicity in mice, were used as immunogens. Four hens were immunized with these immunogens three times. IgY was purified from immunized egg yolk with polyethylene glycol (M.W. 8000) and its anti-H. pylori titer was determined by enzyme linked immunosorbent assay (ELISA). The anti-H. pylori titer reached peak at 8 weeks and was maintained over 20 weeks. H. pylori cells were agglutinated with these purified IgY and the specificity of these purified IgY was detected with immunoblotting.

  • The flagella antigenic variation of nine Bacillus thuringiensis serovar kurstaki temperature-sensitive mutants grown at the permissive temperature (3$0^{\circ}C$) was detected by a serological agglutination between H-antigen and antiserum. The flagella antigens were injected to rabbits to prepared their antisera, and then their homologous and heterologous titers of the antisera were measured. The homologous titers were ranged from 1:6,400 to 1:12,800, but the heterologous titers were very low. The H-antigen of the wild type strain was not agglutinated to 4 heterologous antisera, ts-U23 not to 7, ts-U3l not 5, ts-U32 not to 4, ts-U33 not to 7, ts-U7l not to 4, ts-U73 not to 6, ts-U74 not to 6, ts-U91 not to 4 and ts-U603 not to 4 antisera.

  • A two-year-old male peacock (Pavo cristatus) showed acute watery green diarrhea, followed by neurological signs including torticollis and muscular tremor. By the hemagglutination inhibition test for detecting the antibody against the Newcastle disease virus (NDV), the peacock serum inhibited the agglutination of chicken red blood cells. Grossly distinctive hemorrhagic lesions were found in the mucosa of proventiculus and intestine and lung. The spleen revealed multiple variable sized necrotic foci. Histologically, the mucosa of gastrointestinal track had hemorrhagic lesions and some of them underwent ulceration. The spleen exhibited multiple variable sized necrotic foci in which fibrin exudation was marked. Central nervous system had mild non-suppulative menin-goencephalitis consisting of vasculitis, perivascular hemorrhage, gliosis and meningitis. The cells particularly in the cerebellum were degenerative to necrotic. Some of these nerve cells revealed characteristic peripheral chromatolysis. From the present serological and pathological findings, it is suggested that NDV causing death of peacock was velogenic viscerotropic strain. This is the first report of the occurrence of velogenic viscerotropic NDV in an adult peacock in Korea.

  • Two 4-day-old Thoroughbred foals with acute clinical signs of depression, elevated pulse and respiratory rates, anemia, and jaundice were referred to the equine hospital of Korea Racing Authority. The foals were seemingly normal at birth, but showed clinical signs such as abnormal behavior, jaundice and anemia suddenly after ingestion of the mare's colostrum, followed by death at 4 days after birth. According to the results of the hematology, serum chemistry analysis, jaundice foal agglutination test, and blood groups test, the foals were diagnosed as neonatal isoerythrolysis (NI) caused by the mare's antibodies. These results suggested that the pregnant mares have a potential for NI.

  • Throughout the studies the following experimental results were obtained and so are summarized here. 1) What caused tussah silkworms terrible disease broken ous all over the Korea in 1965, was examined to be “Inclusion body of virus” through microscope. 2) The examined inclusion bodies are easily stained as purple by seller's staining. 3) The proper speed of centrifugation for the purification of inclusion bodies is 1,000 r. p. m for 10 minutes. 4) It is possible, cleanly resulted, to attempt the “Rapid Agglatination Test & Complement Fixation test” with autigen of inclusion bodies. 5) The Anti-polyhedra rabbit serum from antigen of the dilution of 2${\times}$10$\^$6//l$m\ell$ polyhedra made the Ropid Agglutination test possible even with dilution of 1/8 infected pupa blood(antigen).

  • This study was performed to investigate effects of low fat diet and saturated fat supplementation on the function of the immune system. Forty male BALB/c mice average-weighing 15g were divided into two dietary groups: 0.7% safflower oil group and 4.3% beef tallow & 0.7% safflower oil group. Results are as follows; 1) Food intake, body weight, organ weight, agglutination test, differential white cell count and histological examination of spleen were not different in two dietary groups during the experimental period. 2) Delayed-type hypersensitive test of the mice fed 4.3% beef tallow & 0.7% safflower oil was significantly higher than that of the mice fed 0.7% safflower oil ($\alpha$=0.05). 3) Plaque forming cell was significantly reduced at 10th week compared to 7th week in both groups($\alpha$=0.05). Although there was no significant difference between two groups. 0.7% safflower oil groups showed slightly higher plaque forming cell than 4.3% beef tallow & 0.7% safflower oil group.

  • A total of 4,800 chicken sera from Broiler, Layer, and Local chicken were tested to detect the presence of Mycoplasma gallisepticum (Mg) antibody by Rapid Serum Plate and Tube Agglutination Test. Positive cases recorded in this study were 945 (27%) in Broiler, and 436 (36.7%) in layer chicken sera and no. M. gallisepticum antibody could be seen in the local chicken sera. It is evident from the present findings that Mycoplasma gallisepticum infection has been prevailing in this country in improve breeds of chickens.

  • Two kinds of new lectins, CATL-I and CATL-II, were partially purified from the intestine of Chlorostoma argyrostoma turbunatum by physical saline extraction, salt fractionation, ion exchange chromatography and gel filtration. CATL-I and CATL-II were purified 39.4 and 15.8 fold with a yield of 8.8 and 7.4%, respectively. On polyacrylamide gel electrophoresis, CATL-I demonstrated one major and one minor bands. This lectin agglutinated human and other animal erythrocytes nonspecifically and also agglutinated murine splenic lymphocytes. Carbohydrate specificity of the lectins was determined by inhibition of the agglutinability by methyl-${\alpha}-_D$-galactopyranoside and $_L-rhamnose$ at a final concentration of 6 mM. The lectins contained relatively high amounts of acidic amino acids, but the contents of sulfur containing amino acids were very low or was not estimated. Immunochemical studies were carried out to identify some properties of marine animal lectins.

  • A new lectin was purified from Bombyx mori (BML) by physiological saline extraction, ammonium sulfate precipitants, anion exchange column chromatography on DEAE Sephadex A-50 and gel filtration column chromatography on Sephadex G-200. BML agglutinated trypsinized and glutaraldehyde-fixed erythrocytes, and was observed the most high activity with rabbit, chicken erythrocytes and rat splenic lymphocytes. Agglutinability was markedly affected at highly acidic pH, but was relatively stable with high temperature. The effect of metal ions was observed and BML was affected by bivalaent cations, especially depending on $Ca^{2+}$, $Fe^{2+}$, $Mn^{2+}$, whereas, inhibited by $Mg^{2+}$. Agglutination was strongly inhibited by heparin and glucuronic acid. BML was proved to be a glycoprotein which contains 17.16% of sugars. By mass spectrometry analysis, we found 2 bands that were considered as lectin subunits.
