It has been-reported that rabbit serum exhibit an inhibitory action on avian infectious bronchitis virus in embryonating chicken embryo. In this thesis, the biological, serological, physical and chemical properties of normal rabbit serum on the effect of the virus propagation were studied. Throughout the studies, the following experimental results 'were obtained and summarized here. 1. An inhibitory action of rabbit serum on avian infectious bronchitis vrius is due to the normal serum constituents. 2. The nature of the neutralization between normal rabbit serum and the virus is similar to that of the specific antiserum and the virus. 3. Rabbit serum, heat inactivated at $56^{\circ}C$, for 30 minutes, showed its average $log_{10}El,D_{50}Nl$ of 3.7. 4. The inhibitory compound present in the normal rabbit serum is inactivated by means of 5 per cent trypsin, 0.01 M potassium periodate, and absorbed to zymosan. 5. The inhibitory compound was not affected by 0.05 M trichloroacetic acid and 0.005M $KH_2PO_4$. 6. The higher the temperature of heat inactivation of rabbit serum caused the lesser the neutralizing effect on the virus. Heating the serum at $66^{\circ}C$, for 30 minutes brought about a complete loss of the neutralizing index of the serum. 7. No ions, as a cofactor, was incorporated to the inhibitory action of rabbit serum on the virus. 8. The inhibitory compound amays be found in a fraction of serum globulin.

Nature of graft transmissibility of pear abnormal leaf spot disease was examined by various grafting methods in the greenhouse and field. When the diseased and symptomless twigs were collected in winter and grafted in the next spring to the seed-originated healthy root stock, the abnormal leaf spot was developed only in the case of the diseased twigs. Double grafting on a seed-originated healthy root stock, where the diseased and the symptomless twigs were used as 1st and 2nd scions, respectively, developed abnormal leaf spot lesions without exception on the 2nd scions. Tongue-graft with the diseased and the symptomless trees also incited abnormal leaf spots on the both trees. Abnormal leaf spots of were also developed on HN-39, an indicator pear tree, used as a 2nd scion in a double graft test, where the diseased twig and a seed-originated healthy tree were used as the 1st scion and the root stock, respectively. When the diseased twig was top-grafted to the healthy root stock, lesion development of abnormal spot was limited to the grafted twig itself in the 1st year, but expanded to the main branches in the 2nd year, and spread over the whole tree in the 3rd year. This result indicates that the causal agent of abnormal leaf spot disease is transmitted by graft.

In order to investigate the biological properties, pathogenicity and immune responses in artficially infected SPF chickens with Avian infectious bronchitis virus that was isolated from chickens showing IB like signs in southern region of Chung buk. Results obtained throuth the experiments are summarized as follows. 1. From 15 IB suspected cases, two strains of IB virus were isolated, one each from the tracheas and lungs. 2. Infectious bronchitis specific embryo lesions were observed after four serial passages of the isolates in chicken embryos. 3. The field isolates and M-41 strain of IB virus interfered with the replication of Newcastle disease virus in chicken embryos. 4. When specific pathogen free chickens, two week old, were inoculated with the IB virus isolates, clinical respiratory signs as dyspnea, coughing were observed. Airsacculitis was observed by necropsy. 5. AGP antibody positive rates of inoculated SPF chickens were highest on day 14 and lowest on day 36, while HI antibody responses were detected on day 14 in all Groups, the reinoculated Group was shown highest titers. 6.

Infectious mononucleosis(IM) Is an acute self-limiting lymphoproliferative disorder associated with infection by the Epstein-Barr Virus(EBV), with the characteristic triad of fever, sore throat, and cervical or generalized lymphadenopathy. And also there are atypical lymphocytes in the peripheral blood. Cytological findings of IM lymphadenitis are characterized by a florid immunoblastic and atypical lymphoid cell proliferation. However, the small number of cases were studied by fineneedle aspiration cytology(FNAC) even though there was a complexity of lymph node pathology. It is important to recognize the reactive pattern of IM that would initiate EBV study and to avoid unnecessary biopsy We studied findings of lymph node FNAC from 4 patients with EBV infection confirmed by EBV-specific serologic studios. All of the cases were positive for viral capsid antigen(VCA) and one case was positive for anti-EBV nuclear antigen(EBNA). Cytologically, all of the cases exhibited high cellularity and atypia with great numbers of large immunoblastic lymphocytes.

Based on the current importing and exporing regulations for disease control of embryo transfer, some important microorganisms and their control possibilities are reviewed. The results reviewed were sumrnarized as follows: 1. Regulations regarding to the import of embryos vary between importing and exporting countries, but exporting countries examine the donor and embryos for the heaith certification by the requirements of importing countries. 2. Organisms that infect the gametes are 5 kinds of viruses and the diseases caused by them could not be controlled or eradicated using embryo transfer. 3. Organisms that do not infect the gametes are 4 kinds of viruses and the causal organisms are potential candidates for control or eradication by embryo transfer. 4. Organisms that penetrate the zona pellucida and infect the embryo are 6 kinds of viruses including bovine viral diarrhea virus. 5. Organisms that cannot penetrate the zona pellucida or do not infect the embryo are 15 kinds of viruses and the removal from their contaminations are recommended by proper washing procedure and antisera treatment. Bovine and porcine parvovirus, porcine pseudorabies virus and vesicular stomatitis virus are included in these organisms. 6. Bovine embryos that artificially exposed to various pathogenic organisms such as bovine herpes virus, IBR virus, bluetongue virus, bovine viral diarrhea virus and Brucella abortus in vitro are discussed about their infection by several treatments.

Acute infectious mononucleosis, caused by Epstein-Barr virus(EBV), is a self limited lymphoproliferative illness that is common in adolescents and young adults. It shows many complications in multiple organ systems, but the hepatobiliary and the respiratory complication is uncommon. We report a case with thickened gallbladder wall and pneumonia as complications of acute infectious mononucleosis in a child. Also the related literature were reviewed. A 4 year old boy presented with a history of high fever, cough, and abdominal distension for 20days. Physical Examination revealed audible crackles in whole lung field and gross hepatomegaly. Chest X-ray showed pneumonia and liver function tests were abnormal. Ultrasonography and computed tomography revealed a thickened gallbladder wall and hepatosplenomegaly. The diagnosis of primary Epstein-Barr viral infection was eventually made by specific serologic tests. The patients's fever subsided 6 weeks later and pneumonia was recovered around this time. Liver function tests returned near normal 2 months later and ultrasonography of gallbladder was normal at this time.
