BACKGROUND: Ozone (03) induces airway inflammation and hyperresponsiveness which are characteristic features of asthma. There have been few studies observing O3-induced increase in responsiveness of rat airway muscle. Objectives: The aims of this study were to develop an O3-induced nonallergic asthma model using rat tracheal smooth muscle (TSM) and to evaluate the role of airway epithelium on the modulation of muscle responsiveness. METHOD: Five groups of 20 male Sprague-Dawley(SD) rats were exposed to filtered air including 0.12, 0.5, 1.0, or 2.0 ppm 03 for 1 hour. Thirty minutes after the exposure, bronchoalveolar lavage (BAL) and isometric contractile responses of the isolated tracheal ring segments to KCI, acetylcholine (ACh), and electrical field stimulation (EFS) were measured. RESULTS: The percent age of neutrophils was significantly higher and that of alveolar macro-phages in BAL fluid was significantly lower in 2.0 ppm O3-exposed rats than in the control. There were no significant differences in the maximal contractile responses of TSM to KC1, ACh, EFS and in the sensitivity to ACh (ACh-EC50) and EFS (EFS-EC50) between the control group and the ozone exposed group. ACh-EC50 and EFS-EC50 were correlated positively with the percent age of neutrophils and inversely with that of macrophages. Removal of epithelium significantly increased the sensitivity to ACh in O3-exposed group, but not in the control group. CONCLUSION: These findings indicate that O3 induces neutrophilic airway inflammation, but not an increased sensitivity of TSM to ACh or EFS in SD rats. However, O3-induced epithelial damage may be associated with increased muscle response.

Senile entropion remains something of an enigma, with no general agreement as to etiology or best surgical treatment. Little basic research on the problem of senile entropion had been carried out until Dalgleish and Smith inserted metal markers into the various anatomical layers of the lower lid and took lateral rediographs. As the results of their investigations, they showed that surgical intervention should be directed towards the correction of two important features in the etiology of senile entropion-rotation of the tarsal plate and loss of attach ment of skin and orbicularis to the deeper tissues. O'Donoghue and Roden reported that they could be corrected by excising a full-thickness triangle, apex up, from the central part of the lower lid. Three cases of senile entropion and one vase of spastic entropion were treated with the same procedure as O'Donoghue and Roden did except the excision of the redundant skin along the lowere lid margin. The results of our procedure was simple and successful.

Epiretinal membrane formation and membrane contraction are major complications in a variety of ocular conditions, including retinal detachment and penetrating ocular injuries. The epiretinal membrane was derived from pigment epithelial cell and glial cell. In rhegmatogenous retinal detachment, the retinal pigment epithelium was capable of proliferating through retinal tear into the vitreous contributing to preretinal membranes. In this study, we report the ultrastructural features of epiretinal membrane in rhegmatogenous retinal detachment removed during vitreous surgery from 4 patients.

The orbit has roughly the shape of a quadrilateral pyramid whose base corresponds to the orbital margin, and whose apex is the bar of bone between the optic foramen and the medial end of the superior orbital fissure. The orbital dimensions can be measured by plain X-ray or computed tomography. Plain X-ray of the orbit may be difficult for the non-radiologist to identify the measurement landmarks and interpret, whereas computed tomography allows more precise analysis by imaging soft tissue relationships to surrounding orbital bones. Measurement of the orbital dimensions and proptosis using CT does not only contribute to the diagnosis of specific pathologic processes, but also guide the ophthalmologist in planning appropriate medical and surgical management. One hundred and three orbital CT films of Korean adults were measured. The results were as follows: The average orbital width was 38.09 +/- 2.82mm, orbital height was 35.47 +/- 2.28mm, orbital index was 93.80 +/- 6.70, orbital depth was 42.67 +/- 3.56mm, interorbital distance was 24.97 +/- 2.25mm, extraorbital distance was 97.38 +/- 5.14mm and proptosis was 14.28 +/- 3.49mm.

The authors analysed radiologic findings of the posterior fossa lesions as well as incisural and supratentorial lesions in 40 patients who were diagnosed by transfemoral serial vertebral angiography at Catholic Medical Center since October 1972 to April 1976. We also attempted to evaluate the diagnostic value in the diagnosis of the lesions according to the site of involvement. The tumors of the fourth ventricle or vermis demonstrated abnormal findings corresponding to the area of involvement, however the lesion could not be defined accurately with the study. Cerebellar hemispheric or tentorial tumors were diagnosed with considerable accuracy by vertebral angiography. Infratentorial vascular lesions were clearly demonstrated with serial vertebral angiography but the accuracy of diagnosis was argumented with subtraction technique. The evidence of compression of the brain stem was demonstrated with considerable accuracy by serial vertebral angiography. Furthermore exact site and direction of the compression could be outlined with the study. For the posterior temporal or occipital tumors which were not able to diagnose definitely with carotid angiography, considerable diagnostic accuracy was carried by the vertebral angiography. Definite diagnosis of the posterior third ventricle tumors or thalamic lesions was able to obtain with serial vertebral angiography.

BACKGROUND: About 80% of nosocomial Stap hylococcus aureus isolates demonstrate methicillin resistance in Korea. To assess the prevalence of methicillin- resistant S. aureus (MRSA) in the community, we screened the nasal S. aureus isolates from healthy adults. METHODS: Nasal cultures were collected from healthy adults without known risk factors for acquisition of MRSA. Antimicrobial susceptibility of S. aureus isolates against oxacillin were determined using the E- test and the disk diffusion method. Methicillin resistant isolates were tested for the mecA gene by polymerase chain reaction. RESULTS: Total 689 subjects were studied. The point prevalence of S. aureus was 33% (227/689). Sixteen isolates of S. aureus grew on the MRSA screening plates(MAO), of which 5(2.2%) were resistant to oxacillin and positive for the mecA gene. CONCLUSION: Less than 5% (95% CI; 1 ~5%) of the nasal S. aureus isolates in the community were methicillin-resistant.

PURPOSE: To compare mini-mental state examination (MMSE) score between glaucoma group and normal control group and to evaluate the correlation between MMSE score and spectral domain-optical coherence tomography (SD-OCT) values in both groups. METHODS: This prospective study includes thirty glaucoma patients (eleven primary open angle glaucoma and nineteen normal tension glaucoma) and thirty normal controls. Retinal nerve fiber layer (RNFL) and Ganglion cell-inner plexiform layer (GC-IPL) thickness were measured with SD-OCT, and the average values of both eyes were used. The cognitive function was evaluated with MMSE by a single examiner. RESULTS: The mean MMSE scores of glaucoma group and normal group were 26.07 ± 2.95, and 27.00 ± 1.68 respectively (p = 0.137). MMSE score of less than 24 only showed in glaucoma group. MMSE score and RNFL thickness showed statistically no signifance in correlation (R² = 0.236; p = 0.070), however, MMSE score and GC-IPL showed statistically significant correlation (R² = 0.256; p = 0.048). CONCLUSIONS: Glaucoma patients tend to show low cognitive function even though the correlation between glaucoma patient and low cognitive function was not statistically significant. Therefore, the aspect of cognitive depression should be concerned, when facing glaucoma patients.
