OBJECTIVETo study the expression of heme oxygenase-1 (HO-1) gene and protein and the effect of budesonide (BUD) on the HO-1 expression in lung tissues in rats with asthma.

METHODSFifty male Sprague-Dawley rats were randomly divided into 5 groups: normal control, asthma model, dexamethasone (DXM)-, hemin (HO-1 challenger)-or BUD-treated asthma. The asthma model was prepared by ovalbumin sensitization and challenge. The rats were sacrificed 24 hrs after the last challenge. The blood COHb content,and the total cell count and the percentage of differential cells in bronchoalveolar lavage fluid (BALF) were measured. The expression of HO-1 protein and mRNA in lung tissues was detected with immunohistochemistry and RT-PCR, respectively. The airway inflammation situations were evaluated by histopathology.

RESULTSThe airway inflammatory cell infiltration in the DXM-, hemin- and BUD-treated asthma groups was remarkably alleviated compared with that in the asthma model group. Compared with the normal control group, the expression of HO-1 mRNA and protein in lung tissues and the blood COHb content in the asthma model and the DXM-, hemin- and BUD-treated asthma groups were significantly up-regulated. The DXM-, hemin- and BUD-treated asthma groups showed significantly increased expression of HO-1 protein and mRNA in lung tissues compared with the asthma model group. The blood COHb content in the DXM-and the hemin-treated asthma groups was significantly higher than that in the asthma model group.

CONCLUSIONSThe expression of HO-1 protein and mRNA in lung tissues and blood HO-1 activity increased in rats with asthma,suggesting that HO-1 may be involved in the pathogenesis of asthma. HO-1 may have a protective effect against the airway inflammation in asthmatic rats. BUD and DXM can up-regulate the expression of HO-1 protein and mRNA, thus providing protective effects against the airway inflammation in asthmatic rats.

OBJECTIVES: The purpose of this study was to evaluate the microleakage of 4 temporary materials in teeth with Class II-type endodontic access preparations by using a glucose penetration model. MATERIALS AND METHODS: Glucose reaction test was performed to rule out the presence of any reaction between glucose and temporary material. Class II-type endodontic access preparations were made in extracted human premolars with a single root (n = 10). Each experimental group was restored with Caviton (GC), Spacer (Vericom), IRM (Dentsply-Caulk), or Fuji II(GC). Microleakage of four materials used as temporary restorative materials was evaluated by using a glucose penetration model. Data were analyzed by the one-way analysis of variance followed by a multiple-comparison Tukey test. The interface between materials and tooth were examined under a scanning electron microscope (SEM). RESULTS: There was no significant reaction between glucose and temporary materials used in this study. Microleakage was significantly lower for Caviton and Spacer than for Fuji II and IRM. SEM observation showed more intimate adaptation of tooth-restoration interfaces in Caviton and Spacer than in IRM and Fuji II. CONCLUSIONS: Compared to IRM and Fuji II, Caviton and Spacer can be considered better temporary sealing materials in Class II-type endodontic access cavities.

Pelizaeus-Merzbacher disease(PMD) is very rare x-liked recessive leukodystrophy, rather dysmyelinating d due to defect of biosynthesis of proteolipid protein, a component of myelin. Its usual clinical features are stridor, pendular nystagmus, extrapyramidal sign, pyramydal sign, developmental delay and cognition deterioration. Until now PMD has not been published in our country. A 4-year 3 month-old boy developed abnormal eye movement at 3 months of age. His psychomotor development was delayed. On our examination, definite horizontal pendular nystagmus was noted. He showed severe dysarthria, quadriparesis with generalized hyperreflexia, bilateral extensor plantar signs. All laboratory findings including cerebrospinal fluid study were normal. Brain magnetic resonance image (MRI) -revealed diffuse and symmetrical white matter changes in cerebrum and cerebellum. His 23-year-old younger maternal uncle also showed similar clinical history and brain MRI findings. Although the diagnosis of PMD depended on histopathologic investigation, recently MRI can make an important contribution to the diagnosis of PMD with characteristic clinical features. So we could diagnose him and his uncle as PMD.

Acute cerebellitis is a clinically isolated condition showing cerebellar signs such as ataxia, dizziness and dysarthria. Most of them are associated with viral infection, which generally occur in childhood and show benign course without sequelae. Tuberculous cerebellitis is very rare and its outcome is not well described. The aim of this study is to describe the clinical features and course in a patient with tuberculous cerebellits. We will also discuss the possible prognostic factors in acute cerebellitis.

Background: Little is known regarding the functional outcome and quality of life of neuro-ICU survivors. In Korea, the neuro-ICU concept was introduced relatively late and data about long term outcome and predictors concerning functional outcome is scarce. The main objective of this study was to analyze functional outcome and mortality, and to determine prognostic predictors for the outcome in patients admitted to Korean neuro-ICUs. Methods: Consecutive adult (≥ 15-years-of-age) patients admitted to a neuro-ICU due to various causes including ischemic or hemorrhagic stroke, and other neurological or neurosurgical problems such as traumatic brain injury, seizure, or drug intoxication during an 18-month period from July 2008 through December 2009 were included. Demographic and clinical variables were compared between groups stratifi ed based on 6-month modifi ed Rankin scale score. Results: Of 555 patients, there were signifi cant differences in age (P=0.013), sex (P=0.02), hospital stay (P<0.01), neuro-ICU stay (P<0.01), admission diagnosis (P=0.001), intubation (P<0.01), mechanical ventilation (P<0.01), tracheostomy (P<0.01), comorbid conditions such as atrial fi brillation (P<0.01), cardiac complication (P<0.01) and pulmonary complication (P<0.01), a high Therapeutic Intervention Scoring System (TISS-28) score (P<0.01), and a high Acute Physiology and chronic health evaluation (APACHE) II score (P<0.01) between favorable and unfavorable outcome groups. The overall mortality rate was 15.0% (n=83). In multivariable logistic regression analysis, age, sex, high TISS-28, high APACHE II score, intubation, and cardiac complication were independent predictors of unfavorable outcome. Conclusion: The identifi ed predictors for functional outcomes in Korean neuro-ICU patients will be an important aid in diagnosing and treating neuro-ICU patients.

Ocular complications of HIV-related cryptococcal meningitis are reasonably common, but complete binocular blindness as the first manifestation of HIV is extremely rare. A 58-year-old man presented with binocular blindness. He experienced blurred vision for 3 days before the blindness. Mild pleocytosis was present in the cerebrospinal fluid, from which Cryptococcus neoformans was cultured. Serology revealed positivity for HIV antibody. He was treated with antifungal and antiretroviral therapy. This case indicates that HIV-related cryptococcal meningitis should be taken into consideration when determining the cause of unexpected sudden binocular blindness.

BACKGROUND/AIMS: Divided-dose oral sodium phosphate laxative is recommended for bowel cleansing before colonoscopy. Patients need information about the onset and duration of activity of the preparation. This study was designed to develop practical prescribing information for the patients to reduce anxiety and insomnia concerning bowel movement. METHODS: one hundred ninety patients were requested to take 45 mL sodium phosphate in the previous evening and the morning of the procedure, and to complete a questionnaire. The overall quality of bowel cleansing were assessed by endoscopists. RESULTS: Bowel activity began 2.25 (90 percentile: 3.58) hours after the first dose and continued for 6.55 (90 percentile: 8.5) hours. For the second dose the time of onset was 0.85 (90 percentile: 1.67) hours, and bowel activity continued for 3.6 (90 percentile: 5.17) hours. CONCLUSIONS: The onset of bowel activity from the first dose of sodium phosphate starts within 4 hours and it is completed within 8.5 hours for most. We can recommend the patients to take the first dose of NaP solution at 4 p.m. of the previous day of the exam and second dose more than 5 hours earlier before the colonoscopy in the care that the onset of the bowel activity after the first dose take longer thna 4 hours.

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease. In patients with SLE, the prevalence of antiphospholipid antibodies is considerably higher, and is largely responsible for thrombosis. Splenic infarction is a rare complication of arterial thrombosis in patients with SLE. It is important to consider splenic infarction in a patient with SLE complaining of left upper quadrant (LUQ) pain because of the possibility of severe infarction-related complications, such as subcapsular hemorrhage and splenic rupture. We report a case of solitary splenic infarction in a patient with SLE. The only symptom was LUQ pain of 3-day duration. Lupus anticoagulant activity was positive and abdominal-pelvic computed tomography (CT) was consistent with splenic infarction. She did not show any other evidence of thrombotic events. The patient was diagnosed with antiphospholipid syndrome that presented as a splenic infarction in a SLE patient.

OBJECTIVETo understand the incidence rates of agricultural profession-related injuries and the relationship to alcohol consumption.

METHODSA multistage sample of 2366 villagers was selected from Minority Nationality Villages, Heilongjiang province. Face-to-face interviews were conducted by trained interviewers during May 2008. 2198 (92.9%) of the eligible questionnaires were available.

RESULTSIncidence rate of agricultural profession-related injury rate was 11.8% (260/2198) from May 2007 to April 2008. Higher proportions of injuries were seen for males, 30 - 49 year olds, farmers and among those people working on farms for 10 years or more, smoking during farm work, with sleeping disorder, using motor vehicles, and those using agricultural machinery. Rate of alcohol drinking was 29.1% (640/2198) in the month prior to the investigation. Results from logistic regression models showed that alcohol consumption patterns and other alcohol-related behavior were examined in separate logistic models because of collinearity by controlling the variables that were associated with agricultural profession-related injury including sex, age, years of farm work, driving a motor vehicle, and agricultural machinery use etc. In each model, the reference group was those villagers who did not drink in the past month. The odds of injury among villagers with history of past month drinking, who drank distilled spirits, and alcohol drinking at breakfast and lunch were 1.80 (95%CI: 1.24 - 2.62), 2.09 (95%CI: 1.38 - 3.15), 2.15(95%CI: 1.43 - 3.22) respectively. The odds of agricultural injury also significantly increased with greater average amounts of pure alcohol per day, with increased frequency of drinking per week, and reported years of drinking.

CONCLUSIONIntervention efforts should include increasing awareness about alcohol drinking as a major risk factor causing agricultural injuries as well as controlling alcohol drinking, improving knowledge about driving motor vehicle and using agricultural machinery.
