Migration and Attacking Ability of Bursaphelenchus mucronatus in Pinus thunbergii Stem Cuttings
To understand how Bursaphelenchus xylophilus kills pine trees, the differences between the effects of B. xylophilus and B. mucronatus on pine trees are usually compared. In this study, the migration and attacking ability of a non-pathogenic B. mucronatus in Pinus thunbergii were investigated. The distribution of B. mucronatus and the number of dead epithelial cells resulting from inoculation were compared with those of the pathogenic B. xylophilus. Although B. mucronatus is non-pathogenic in pines, its distribution pattern in P. thunbergii was the same as that of B. xylophilus. We therefore concluded that the non-pathogenicity of B. mucronatus could not be attributed to its migration ability. The sparse and sporadic attacking pattern of B. mucronatus was also the same as that of B. xylophilus. However, the number and area of the dead epithelial cells in pine cuttings inoculated with B. mucronatus were smaller than in those cuttings inoculated with B. xylophilus, meaning that the attacking ability of B. mucronatus is weaker than that of B. xylophilus. Therefore, we concluded that the weaker attacking ability of B. mucronatus might be the factor responsible for the non-pathogenicity

Long-Term Outcome of Primary Endoscopic Realignment for Bulbous Urethral Injuries: Risk Factors of Urethral Stricture
Purpose Although endoscopic realignment has been accepted as a standard treatment for urethral injuries, the long-term follow-up data on this procedure are not sufficient. We report the long-term outcome of primary endoscopic realignment in bulbous urethral injuries. Methods Patients with bulbous urethral injuries were treated by primary endoscopic realignment between 1991 and 2005. The operative procedure included suprapubic cystostomy and transurethral catheterization using a guide wire, within 72 hours of injury. The study population included 51 patients with a minimum follow-up duration of 5 years. Results The most common causes of the injuries were straddle injury from falling down (74.5%), and pelvic bone fracture (7.8%). Gross hematuria was the most common complaint (92.2%). Twenty-three patients (45.1%) had complete urethral injuries. The mean time to operation after the injury was 38.8±43.2 hours. The mean operation time and mean indwelling time of a urethral Foley catheter were 55.5±37.6 minutes and 22.0±11.9 days, respectively. Twenty out of 51 patients (39.2%) were diagnosed with urethral stricture in 89.1±36.6 months after surgery. A multivariate analysis revealed that young age and operation time were independent risk factors for strictures as a complication of urethral realignment (hazard ratio [HR], 6.554, P=0.032; HR, 6.206, P=0.035). Conclusions Urethral stricture commonly developed as a postoperative complication of primary endoscopic urethral realignment for bulbous urethral injury, especially in young age and long operation time
