Objective: The aim of this study was assessment of the relationship between airway space and facial morphology in Class III children with nasal obstruction. Methods: For this study, 100 Class III children (50 boys and 50 girls) were chosen. All subjects were refered to ENT, due to nasal obstruction. Airway space measurements and facial morphology measurements were measured on lateral cephalometric radiograph. Pearson correlation analysis was used to assess the relationship between airway space and facial morphology Results: Ramal height, SNA, SNB, PFH, FHR and facial plane angle were positively related to upper PAS, and sum of saddle angle, articular angle, and genial angle, SN-GoGn, Y-axis to SN and FMA negatively related to upper PAS. Genial angle, FMA were positively related to lower PAS, and articular angle, facial depth, PFH and FHR negatively related to lower PAS. PCBL, ramal height, Mn. body length, Mn. body length to ACBL, facial depth, facial length, PFH and AFH were positively related to tonsil size. Sum of saddle angle, articular angle, genial angle, facial length, AFH, FMA and LFH were positively related to tongue gap, and IMPA and overbite was negatively related to tongue gap. Upper PAS, related to size of adenoid tissue, was mainly related to posterior facial dimension following a vertical growth pattern of face and mandibular rotation. Lower PAS and tonsil size, related to anterior-posterior tongue base position, were significantly related to each other. Lower PAS was related to growth pattern of mandible, and tonsil size was related to size of mandible and horizontal growth pattern of face. Tongue gap was related to anterior facial dimension following a vertical growth pattern of face. Conclusion: Significant relationship exists between airway space and facial morphology.

In order to find out the basic information for salt tolerance in vice (Oryza sativa L.), effects of NaCl treatment on absorption of inorganic components and growth were investigated in 6 japonica and 5 tongil varieties and compared to the salt tolerance variety, Annapurna. The absorption of N and $\textrm{P}_2\textrm{O}_5$ was less repressed than that of $\textrm{K}_2\textrm{O}$, MgO, CaO, and $\textrm{Si}\textrm{O}_2$ which were a little affected by NaCl treatment. $\textrm{K}_2\textrm{O}$ was the most highly repressed component in the absorption of inorganic components, followed by MgO, CaO, total-N, $\textrm{P}_2\textrm{O}_5$ and $\textrm{Si}\textrm{O}_2$. $\textrm{Na}_2\textrm{O}$ content was increased about twenty times to the control at 30days after NaCl treatment, and tonsil varieties more than absorbed japonica ones. Dry weight of japonica varieties by NaCl treatment was less reduced than that of tonsil varieties, followed by Seomjinbyeo, Sinseonchalbyeo, Nakdongbyeo, Daechoungbyeo, Dongjinbyeo and Chuchoungbyeo in japonica group, and Milyang30, Gayeabyeo, Jangseongbyeo, Chilseongbyeo and Taebackbyeo in tonsil group. The relationship between dry weight reduction and Na/K ratio showed positively significant correlation in rice.

To investigate the etiology, pathogenicity and virological properties of NYJ-1-87 strain of Aujeszky's disease virus (ADV) that was isolated from the diseased piglet in Korea, the virus at $10^{6.0}TCID_{50}/0.1ml$ was inoculated intranasally and subcutaneously into 30 to 35 days-old piglets. Results obtained through the experiments were summarized as follows. 1. Ten of the infected piglets were clinically observed for 15 days. On the 2nd day post-inoculation(pi), the signs of pyrexia, anorexia and convulsion were noted. On the 4th to 7th days pi, nervous signs of incoordination and intermittent spasm were shown in the most of piglets, and one out of 5 piglets infected intranasally was died with severe nervous signs at the 7th day pi. The signs became relieved on the 8th day pi and all of remainder were completely recovered on the 13th to 14th days pi. 2. In hematological study, prominent decrease in the number of total leukocyte and lymphocyte was shown in the ADV-infected piglets on the 6th day pi. On the 8th day pi, the cell numbers were slightly increased and returned to normal level on the 10th day pi. 3. Viral excretion of the ADV-inoculated piglets was examined by swabbing of nasal and oral cavities, and rectal feces. During the periods of the 3rd to 11th days pi, the virus was excreted intermittently from nasal and oral cavities, and rectal feces. The nasal excretions were shown the highest virus concentration of $10^{5.2}TCID_{50}/0.1ml$ at the 5th day pi. 4. Recovery of the inoculated virus from various organs of the piglets that were died or experimentally slaughtered was attempted, and the virus was isolated from the tissues of brain and tonsil by the cultured cell-inoculation method. The highest recovery rate was noted in the tonsil. By indirect immunofluorescence antibody assay using ADV-monoclonal antibody, the viral antigens were detected in tissues of spleen and liver as well as brain and tonsil on the 7th to 9th days pi. The virus was not isolated from blood and the tissues of lung and kidney throughout the experiments. 5. Titers of virus neutralizing antibody in the piglets experimentally infected with ADV became increased after the 6th to 9th days pi in both of intranasal and subcutaneous inoculation showing the highest titers of 64 to 128 on the 29th day pi. When the antibody levels were measured by radial immunodiffusion enzyme assay, the reactive diameter was enlarged to be positive after the 4th to 6th days pi in both of intranasal and subcutaneous inoculation showing the largest diameter of 13 to 14mm on the 29th day pi.

The nuclear phosphoprotein p53 is expressed in all normal cells and appears to function in cell cycle regulation. Abnormally high levels of the protein are found in many different types of cancer. In human cancer overexpression of p53 is associated with point mutations within highly conserved regions of p53 gene. These altered genes encode stable p53 proteins that can detected by standard immunocytochemical techniques unable to detect rapidly degraded wild-type protein. Using of a monoclonal antibody to p53 antigen, immunocytochemical analysis of 29 squamous cell carcinomas of tongue(n= 19) and tonsil(n= 10) was performed. Non-tumor nuclei showed all negative reactivity. Positive reactivity was found in 4/29(13.8%)of SCCs of tongue and tonsil. In sizes of primary tumor, the cases over 4cm showed more positive reactivity than the cases under 4cm(p < 0.05). There was no stastical correlation between the reactivity and histopathologic grades, the primary sites of tumor or the presence of cervical metastasis.

Foreign holies in the upper aerodigestive tract are an important cause of morbity and mortality in older adults and children under 3 years of age. Fish and chicken bones are the usual foreign bodies lodged in the hypopharynx, and most of them lodge In the lower pole of a tonsil, at the base of the tongue, at the lateral wall of the pharynx, or in a vallecula. Recently, the authors experienced a case of aspiration pneumonia caused by chronic local inflammatory reaction of the posterior wall of the hypopharynx originated from a special foreign body.

Thirty-day-old piglets were intranasally or subcutaneously inoculated with 2ml of Aujeszky's disease virus, NYJ-1 strain, at the titer of $10^{6.75}$ $TCID_{50}/0.1ml$, that was isolated from the diseased piglets in Korea, and histopathological studies were performed to elucidate the pathognomonic characters of the isolate. Results obtained through the experiments were as follows: 1. Major clinical signs on the 2nd and 3rd days post inoculation (p.i.) were fever, anorexia and dyspnea. On the 6th and 7th days p.i., nervous signs, severe dyspnea and salivation were observed in the group of intranasal inoculation, and one out of 3 piglets in this group died on the 7th day p.i.. General signs were more severe in the group of intranasal inoculation than the group of subcntaneous injection. Between the 8th and l0th days p.i., the signs subsided and the piglets were completely recovered from the illness. 2. Hematologically, most of the inoculated pigs showed a mild lymphocytopenia on the 5th and 6th days p.i.. 3. By necropsy, swelling and hemorrhagic lesions were observed in tonsil, central nervous system and lung. No specific changes were grossly found in other parenchymatous organs. 4. In histopathological study, degeneration and necrosis of nervous cells, non-suppurative meningoencephalitis, diffuse or focal gliosis, perivascular cutting and degeneration of ganglion cells were observed in central nervous system, and swelling and hemorrhagic changes were shown in the tissues of liver, lung and lymph nodes. 5. By indirect immunofluorescence antibody assay using ADV-monoclonal antibody, specific ADV antigens were detected in the tissues of tonsil, brain and spleen of the succumbed piglet. However, in the experimentally slaughtered piglets, the specific reactions were noted only in the tonsils.

Multiplex PCR and immunohistochemistry were used to detect and differentiate between porcine circovirus (PCV) type-I and the PCV associated with postweaning multisystemic wasting syndrome (PMWS). Unique DNA product to PCV type-II was confirmed the some organs including lymph nodes, tonsil and spleen from eight pigs in Jeju by multiplex PCR. In this study, the samples were tested by a multiplex PCR assay to determine the type of PCV in each case; all cases were PCV type-II positive. PCV type-II was identified not only in typical PMWS cases, but also in field cases submitted with various clinical histories, some of which were not suggestive of PMWS. Immunohistochemically PCV type-II antigen was detected in macrophage-like cells in the tonsil, liver, lymph nodes and spleen, while some hepatocytes and renal tubular epithelial cells were also positive to the virus. This study suggested that PCV type-II is one of the causative agents of PMWS as well as the major type of PCV in the affected pigs in Jeju.
