BACKGROUND: In chronic airway disease, mucus secretion in increased, but extraction of mucin, which is the main component of mucus secretion, is a very complicated and limited in clinical use. Recently, monoclonal antibody for mucin was developed for possible clinical use. In this study, cellular analysis and quantification of respiratory mucin in sputum of patients with chronic airway diseases were performed. METHOD: Sputum was collected from patients with asthma(n=33), bronchiectasis(n=8) or chronic bronchitis(n=13) by spontaneous expectoration or by hypertonic saline induction, Collected sputums was treated by 0.1% dithiotreitol to dissociate the disulfide bond of the mucus and filtered through a nylon gauze. Total cell count, viability and differential count were measured. For detection of mucin, collected samples were treated with sodium dodoecyl sulfate polyacrylamide gel electrophoresis and then with monoclonal antibody(HMO2), as the primary antibody, and PAS stain. The amount of mucin was measured with ELISA by HMO2. Correlation with clinical information, cellular analysis, and amount of measured mucin were analyzed. RESULTS: Total cell counts of sputum were significantly increased in patients with bronchiectasis but viability remained the same. Eosinophils were significantly increased in patients with asthma, neutrophils in bronchiectasis chronic bronchitis, respectively (p<0.05). The results of Western blotting and PAS staining confirmed the presence of glycoproteins and matched? with mucin. The amounts of mucin measured by ELISA were not significantly different among the disease groups. Significant correlation was identified between the amount of mucin and viability(r=-0.482, p<0.05). CONCLUSION: Inflammatory cells in the sputum of those with chronic airway disease were different for each disease type. Measurement of mucin by ELISA via monoclonal antibodies may be a simple method for the evaluation of chronic airway disease.

PURPOSE: To evaluate whether the presence of a peripheral echogenic rim surrounding internal low echogenicityis helpful in the diagnosis of atypical hepatic hemangioma. MATERIALS AND METHODS: Within a two-year period, aretrospective review of the sonographic appearances of 24 atypical hemangiomas in 21 patients was performed. Diagnosis was made by dynamic and delayed enhanced CT, MR imaging or clinical follow up for one year, including follow-up sonogram. The sonographic appearances of these hemangiomas were analyzed for pattern and thickness ofthe echogenic rim, internal echo pattern, shape, and size. Additionally, forty six lesions of hepatoma, metastasis, abscess and intrahepatic cholangiocarcinoma confirmed by pathology within the same period were also evaluated for the presence of echogenic rim. RESULTS: Twenty-three of 24 lesions showed an echogenic rim ; these were thick in nine cases, and thin in 14 cases. The thickness of the rim was either uniform(n=10) or eccentric(n=13). The average maximum diameter of atypical hemangioma was 4.4cm (range of diameters, 1.5-12cm). The internal echo pattern was partially or entirely hypoechoic in 15 lesions, homogeneously isoechoic in three, and mixed insix cases. Twenty-one lesions were round, and the shape of three was irregular. The other forty six masses including hepatocellular carcinoma, metastases, cholangiocarcinoma and hepatic abscesses did not show an echogenicrim. CONCLUSIONS: The presence of a sonographic echogenic rim in a hepatic mass may help in the diagnosis ofhepatic hemangioma.

Background:
To solve the difficulty in determining the appropriate treatment regimen for patients infected with extensively drug-resistant Acinetobacter baumannii (XDRAB), it is necessary to develop various strategies to increase the therapeutic effect of antimicrobial agents. The purpose of this study was to select the treatment combination showing the greatest antimicrobial effect among seven candidate antimicrobial substances.
Methods:
Seven strains of XDRAB were used in this study. The composition of the treatment consisted of colistin as the base and one of the seven antimicrobial substances, doripenem, minocycline, tigecycline, linezolid, fusidic acid, vancomycin, or alyteserin E4K peptide. The interaction between the drugs in each combination was evaluated by measuring the synergy rates using time-kill analysis.
Results:
The synergy rates of the seven combinations tested in the time-kill assay in this study were as follows, in descending order from the combination with the highest synergy rate: colistin + minocycline (57.1%), colistin + alyteserin E4K (50.0%), colistin + tigecycline (42.9%), colistin + vancomycin (28.6%), colistin + doripenem (14.3%), colistin + fusidic acid (14.3%), and colistin + linzolid (0%). None of the combinations showed antagonism. The three combinations showing bactericidal activity and the rates of their bactericidal activity were colistin + alyteserin E4K combination (33.3%), colistin + minocycline (14.3%), and colistin + vancomycin (14.3%).
Conclusion
The colistin + minocycline and colistin + alyteserin E4K treatment combinations, which showed high synergy rates, can be considered as promising candidates for future in vivo experiments evaluating combination therapies.

Background:
The impact of persistent coronavirus disease 2019 (COVID-19) symptoms on quality of life remains unclear. This study aimed to describe such persistent symptoms and their relationships with quality of life, including clinical frailty and subjective health status.
Methods:
A prospective longitudinal 3-month follow-up survey monitored symptoms, health quality, support needs, frailty, and employment.
Results:
A total of 82 patients with a mean age of 52 years (ranging from 23–84 years) were enrolled, including 48 (58.6%) men, and 34 (41.5%) women. The fully active status decreased from 87.8% before admission to 78.1% post discharge. Two patients (2.4%) were ambulatory and capable of all self-care but unable to carry out any work-related activities 12 weeks after discharge. Clinical frailty scale (CFS) levels 1, 2, 3 and 4 changed drastically between admission and 12 weeks later after discharge. Just after admission, the median EuroQol visual analogue scales (EQ-VAS) was 82.23 (± 14.38), and it decreased to 78.10 (± 16.02) 12 weeks after discharge; 62 (75.6%) of patients reported at least one symptom 12 weeks after discharge. The most frequent symptom was fatigue followed by smell disorder, anxiety, sleep disorder, headache, depressive mood, dyspnea, and taste disorder. CFS was definitively associated with fatigue. Decreased EQ-VAS was associated with fatigue and palpitation, cough, taste disorder, and chest pain. EQ-VAS was worse in women (28%) than in men. Compared with regular outpatient clinic visits before admission, 21 patients (25.6%) reported increased outpatient clinic visits, one (1.4%) reported readmission, and one (1.4%) reported emergency room visits. Six of the 54 (77.1%) patients who were employed before admission lost their jobs. And most vulnerable type was self-employed, because three selfemployed job workers were not working at 12 weeks after discharge.
Conclusion
COVID-19 sequelae should not be underestimated. We find a decrease in health quality and increase in psychological problems in discharged COVID-19 patients, and some patients experience unemployment. The number of patients suffering from COVID-19 sequelae would not be negligible considering there are more than one million COVID-19 infection cases in Korea. Hence, the government should start a systematic monitoring system for discharged patients and prepare timely medical and social interventions accordingly.

PURPOSE: To evaluate the safety of transgression of the bowel during intraperitoneal percutaneous catheter placement in an animal model. MATERIALS AND METHODS: Eight 8-F straight catheters were percutaneously insertedinto the small and large bowel of eight rabbits. In four animals, the catheters were left in place until autopsy, whereas in the remaining four, the catheters were withdrawn five days after insertion. Autopsy was performed inall animals ten days after catheter placement, and gross and microscopic examination was carried out. RESULTS: Transgressing the bowel during intraperitoneal percutaneous catheter placement did not contribute to any clinically significant complications. At autopsy, there was no bowel leakage, peritonitis, or abscess, although peritoneal adhesions were found around the catheter tract. CONCLUSION: Although further study is warranted, ourstudy with an animal model indicated that transgression of the intestine during percutaneous placement of an intraabdominal catheter did not produce significant complications.

BACKGROUND: One hundred years after the discovery of the ABO blood group system by Landsteiner, agglutination is still the most widely used method for determining the blood grouping and for antibody detection. Yet the demand for suitable automated systems is obvious in the field of transfusion. QWALYS-3 (DIAGAST, Loos Cedex, France) is a fully automated system for determining the ABO and RhD grouping and for antibody screening. We evaluated the ABO and RhD grouping and antibody screening test of the QWALYS-3. METHODS: The ABO and RhD grouping and the antibody screening test were performed by the QWALYS-3 system and the results were compared to the manual methods for the ABO and RhD grouping and to the micro column agglutination method (DiaMed-ID system) for antibody screening. RESULTS: For 574 of 574 clinical samples, there was complete concordance between the QWALYS-3 and the manual methods for determining the ABO and RhD grouping. The concordance rate between the QWALYS-3 and the micro column agglutination method for antibody screening in 210 clinical samples was 97.1%. CONCLUSION: The QWALYS-3 system had a good concordance rate compared to the manual method and the micro column agglutination method. The QWALYS-3 system was robust and it gave accurate results during this evaluation. The QWALYS-3 system will contribute to achieving full automation of all the necessary blood bank tests.
