  • The gross alpha analysis of nasal smear samples for the radiation emergency and the additional follow-up steps were established. Cotton swab sticks using in local hospitals for nasal smear in Korea were used for the verification. The measurement results of standard samples spiked with certified reference source were well agreed within ${\pm}20%$ compared with reference values. The clearance ratio of smear samples conducted with wet smear condition showed higher value. To eliminate the quenching effect of liquid scintillation samples, dry of smear samples should be followed up before counting samples. Based on the measurement results, medical decision levels and internal dose assessment were established for the victims in the beginning of radiation emergency.

  • This study was done to analyze the effects of a smear in the nasal cavity against nosocomial Infection. The smear used was mupirocin, and the study centered on infection which constitutes the majority of nosocomial infections called MRSA. The data were collected between March 23 1998 and June 31 of the same year in a university hospital in the Kyongi Province, and is made up of a experimental group of 14 patients who were given nasal cavity smears and a control group of 16 patients who were not given nasal cavity smears. The data were analyzed through frequency and the Chi-square tests and gave forth these results. 1. Of the experimental group 28.6% developed nosocomial infections while 62.5% of the control group developed infections. This difference was significant. 2. In the experimental group, all of the patients developed infections within the first week in the ICU, while 80% of the control group developed infections in the first week and 20% in the second week. The difference was not as marked here. 3. In the experimental group the DM group 66.7% contracted MRSA while 18.2% developed it in the non-DM group showing that the DM group had infection rate was 3.7 times higher than the non-DM groups. In the control group the DM group had a 100% infection rate while 50% of the non-DM group developed it. Overall the DM group's rate infection was 2.4 times higher than the non-DM group. 4. In the experimental group, 37.55% of the patients who had a tracheostomy developed it while 16.7% of the patients who did not have a tracheostomy developed infections. In the control group, 62.5% of the patients who had tracheostomy, and 37.5% of the patients who did not have tracheostomies developed infections. Those who had tracheostomies, and the control group had double the rate contracting infections. From these results we can see that nasal cavity smears are effective against nosocomial infections. In spite of the smears, patients with the diabetes mellitus had a high MRSA infection rate, which requires new alternative treatments.

  • Inflammatory sinonasal disease was diagnosed in five dogs and two cats with clinical signs of nasal discharge and epistaxis. Survey radiography and CT were performed in all of patients. CT scan of the rostral cranium was performed with a thickness of 2 or 5 mm. Nasal cytology and culture from nasal smear were performed immediately after CT examination. Remarkable increase of opacity in the nasal cavities and frontal sinuses was observed in only 3 cases. On CT images, the cavitating lesions were isodense in nasal cavity (7 cases), frontal sinuses (3 cases), and nasopharynx (2 cases) with destruction of the nasal septum (4 cases), maxillary turbinates (5 cases), maxilla (3 cases), and hard palate (3 cases). The lesions were enhanced after intravenous contrast administration in 5 cases and were not enhanced in 2 cases. Inflammatory cells were observed in nasal cytology. Most of the cultures from nasal smear were bacteria. CT is useful to diagnose sinonasal disease and is more accurate in demonstrating the extent and character of lesions of nasal cavity than radiography.
