Case 1 was showed severe caughing and nasal discharge, who was one of 5-month-old 18 male sheep taking inspection for MCF experiment. Pathological examination of case 1 was conducted. Macroscopic observations were the foamy sticky fluids in nasal and tracheal cavity, the grey spots with 2-4 mm diameter on the surface of lung. Histopathological observations were severe eosinophil and other round cell infiltration in general organs including lung, trachea, small intestine, large intestine, liver. Also, in the lung, there were parasite-cutting lesions in some alveolar spaces and bronchioles. Following these observations, case 1 was diagnosed as ovine lungworm infection.

Purpose: The aim of this study was to evaluate the skeletal and dentoalveolar dimensional changes following surgically-assisted rapid maxillary expansion (SARME). Patients & methods: Thirteen adults who had been treated by SARME for transverse maxillary deficiency from May 2000 to December 2003 were evaluated. The SARME procedure was the subtotal Le Fort I osteotomy combined with pterygomaxillary separation and anterior midpalatal osteotomy. Dental study casts and posteroanterior cephalometric radiographs were taken before operation, after removal of expansion device, and follow up period. Nasal cavity width, skeletal and dentoalveolar parameters were measured pre- and post-operatively. Results: 1. Mean nasal cavity width was increased 12%$(0{\sim}21%)$ of total expansion after retention. 2. Mean maxillary interdental width was increased 70%$(47{\sim}99%)$, 95%$(84{\sim}115%)$, and 77%$(57{\sim}94%)$ of total expansion in the canine, the first premolar, and the first molar region, respectively after retention. 3. Mean maxillary alveolar bone width was increased 66%$(42{\sim}84%)$, 74%$(42{\sim}94%)$, and 57%$(31{\sim}78%)$ of total expansion in the canine, the first premolar, and the first molar region, respectively after retention. 4. Mean palatal vault depth was decreased 1.3 mm ($0.5{\sim}2.0$ mm) after retention. 5. Mean interdental and alveolar bone width of the mandibular canine and intermolar width of mandible were slight increased as maxilla was expanded after retention. 6. There were statistical differences between preoperative and postoperative values of nasal cavity, all maxillary interdental and interalveolar widths, palatal vault depth, mandibular interdental and interalveolar width of canine(paired t-test, p<0.05). 7. The maxillary interdental and alveolar bone width were decreased approximately 25% of total expansion by relapse at follow up period. Conclusion: In conclusion, most amounts of maxillary interdental expansions were acquired with the expansion of the maxilla by SARME. For preventing the relapse, approximately 25% of the overexpansion was needed.

Maxillectomy is performed to remove the tumor in the palate, maxillary sinus, buccal mucosa or nasal cavity. The resection range depends on the size and the extent of the tumor and it affects speech production or cause nasal regurgitation during feeding. Obturator can occlude an opening such as an oro-nasal fistula and protect the defect area. Successful reconstrucion of the patient's oral cavity who have gone over the maxillectomy is a difficult task. The condition and number of teeth, the remaining support area, and the extent of the defect area have a great influence on manufacturing the obturator. If these factors are disadvantageous, the prognosis of the prosthesis is uncertain. The final obturator must have a sufficient retention in the patient's oral cavity and must not irritate the surrounding tissue and support area where the resection was performed.In this case, a 55 year old female went through the maxillectomy and the only 3 teeth remained. And the retention of the maxillary prosthesis seems to be poor. So that, we fabricated the closed hollow obturator which has reduced weight compared to the conventional obturator. Consequently the closed hollow obturator can give better sealing and the adaptation.

Isolation and identification of Mycoplasma were performed to clarify Mycoplasma infection of mice fed by conventional feeding at two ($K_1$, $K_2$) institutes in Korea. The twenty mice to be tested were randomly sampled from each of 10 breeding colonies in respective institute. Identification of the Mycoplasma strains isolated from the nasal cavity, lung and synovia of mice was made according to the morphology of colonies, biological and biochemical properties with special reference to M. pulmonis, M. arthrotodis and M. neurolyticum. In addition, growth inhibition test was performed using hyperimmune rabbit antisera to the strain PG-22 of M. pulmonis, the strain PG-6 of M, arthritidis and the strain PG-28 of M. neurolyticum and also differentiation of isolates from L-form bacteria was dont by Dieses staining and culture method with passage of the isolates on liquid media eliminated antibacterial drug. On the other hand, a total of 13 strains out of the 44 isolated M. pulmonis from mice was investigated for their susceptibility against 16 antibiotics in vitro. The antibiotic sensitivity test was made using $3{\times}10^4$ organisms/0.3ml on each plate(90mm diameter) with antibiotic mono-or tri-disk. The results obtained are summarized as follows: 1. Out of 20 mice from 10 breeding colonies in Kl institute, mycoplasma-like strains from the nasal cavity of 16 mice(80%) and from the lung of 8 mice(40%) were isolated, while out of 20 mice in K2 institute, M-like strains were isolated from the nasal cavity of 14 mice(70%) and from the lung of 6 mice(30%). However, no mycoplasma-like organisms were isolated from the synovia of the 40 mice examined. All the 44 strains isolated were identified as the organisms of M. pulmonis. 2. Out of the 16 antibiotics tested, penicillin, oleandomycin and bacitracin showed no activity against all the 13 M. pulmonis strains. On the contrary, lincomycin, clindamycin, chloramphenicol, tetracycline, minocycline, kanamycin, gentamycin and tobramycin showed high activity with three different antibiotic concentration of tridisk, but amikasin and spiramycin showed intermediate activity. Other antibiotics such as polymyxin B and colistin showed low activity, while erythromycin showed lower activity than others.

Inclusion complexes of ketoconazole(KT) with ${\alpha}^_$, ${\beta}^_$cyclodextrin(CD) and $dimethy1-{\beta}-cyclodextrin$ (CD) and $dimethy1-{\beta}-cyclodextrin(DM{\beta}CD)$ as nasal absorption enhancer were prepared in 1: 2 molar ratios by freeze-drying and solvent evaporation methods. In order to compare with the intrinsic absorptivity of KT in the jejunum(J) and the nasal cavity(N), the in situ simultaneous perfusion method was employed. The in situ recirculation study revealed that KT-CD inclusion complexes with the greater stability constant and the faster dissolution rate proportionally increased the absorption of KT in the J and N of rats. The rank order of apparent KT permeability$(P_{app}\;:\;cm/sec\;{\time}\;1O^{-5}{\pm}S.E.)$, corrected by surface area of absorption, was $5.10{\pm}0.3(N,\; KT-DM{\beta}CD)$ )> $4.13{\pm}0.4(N,\;KT-{\beta}-CD)$ )> $3.52{\pm}0.2(N,\;KT-{\alpha}-CD)$ )> $2.76{\pm}0.3(J,\; KT-DM{\beta}CD)$ )> $2.61{\pm}0.5(J,\;KT-{\beta}-CD)$ )> $2.42{\pm}0.4(J,\;KT-{\alpha}-CD)$ at pH 4.0. The in crease in permeability of $KT-DM{\beta}CD$ inclusion complex was 2.6 folds in the J and 4.5 folds in the N when the perfusing solution was changed from the buffer(pH 4.0) to saline. The absorption rate of $KT-DM{\beta}CD$ inclusion complex after nasal administration was more rapid than those of ketoconazole alone and $KT-DM{\beta}CD$ inclusion complex after oral administration to rats. In comparision with an oral administration of ketoconazole suspension in corn oil, the relative bioavailability was calculated 137.3% for the oral and 195.0% for nasal $KT-DM{\beta}CD$ inclusion complex in rats. The present results suggest that $KT-DM{\beta}CD$ inclusion complex may serve as a potential nasal absorption enhancer for the nasal delivery of ketoconazole.

Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that causes infections in different parts of the body and causes skin and soft tissue infections (SSTI). The present study examined the antimicrobial resistance patterns and molecular epidemiological characteristics of MRSA isolated from nasal swabs in clinical patients. SCCmec type of MRSA isolates from clinical patients were analyzed: 24 cases were SCCmec type-II; two cases were type-II/IVa; one case was type-II/V; one case was type-IVa; 11 cases were not-typeable. The mec complex type of MRSA isolates from clinical patients were analyzed: 29 cases were mec complex type A, and 10 cases were not-typeable, but type B was not found in the present study. In conclusion, SCCmec type-II and mec complex type A were the most dominant MRSA subtypes among the MRSA isolates from a nasal swab of patients, and the results were similar to other studies on hospital-acquired MRSA (HA-MRSA). These results can not only provide basic data for hospital infection management but also be a good guideline for MRSA infections in the Republic of Korea.

Midline Granulcma(Malignant midline reticulosis) of upper respiratory tract was known as one of the fatal diseases that involve the nasal cavity, paranasal sinuses, pharynx and larynx, with progressive localized necrotizing inflammation and granuloma formation. The disease was first described in 1897 by McBride and after Stewart many clinical and histological studies have been done in 1933. But its etiology is still unclear and therapeutic methods are still under development. The authors carried out a clinical study of 15 cases which were diagnosed and treated as midline granuloma, including 7 cases which received combination radiation and steroid therapy from January 1964 to December 1980. The results are as follows: 1) Age and Sex distribution: 6 cases fell into the ages from 30 to 39 years: 13 cases (87%) were male and 2 cases (13%) were female. 2) Primary lesion sites were nasal cavity and paranasal sinuses area (8 cases: 53%), palatine tonsil (3 cases: 20%) and pharynx (2 cases: 13%) in order. 3) Common symptoms were nasal stuffiness and sore throat (6 cases: 40%), headache (5 cases: 33%), nasal discharge and facial edema (3 cases: 20%) in order. 4) Microorganisms were identified in 4 cases: staphylococcus in 2 cases, pseudomonas in 1 case and streptococcus in 1 case. 5) All 7 cases who received combination radiation and steroid therapy revealed complete regression and no recurrence. 6) Among the 5 cases, who received steroid and antibiotic therapy, 2 cases died and other 3 cases improved temporarily and then developed aggrevation of symptoms.

Angiomyolipomas are usually found in the kidneys of patients with tuberous sclerosis. They occur less frequently in organs such as the liver, the oral cavity, the nasal cavity, the heart, the large intestines, and the lungs. Angiomyolipomas of the skin are extremely rare, and cutaneous angiomyolipomas generally occur on the elbow, the ends of digits, the ear, and the glabella. Herein we present a rare case of angiomyolipoma occurring on the face-specifically, the right upper eyelid. We propose that upper eyelid angiomyolipoma is a hamartomatous, rather than neoplastic, lesion. Although angiomyolipoma in the periocular area is rare, it should be considered in the differential diagnosis of clinically benign masses. and regular follow-up is warranted.
