    Notes: Summary Presented is the case of a 63-year-old woman, with a 30-year history of rheumatoid arthritis, whose hip was completely destroyed and accompanied with enlargement of the iliopsoas bursa. Preoperative diagnosis was confirmed by computed tomography, magnetic resonance (MR) imaging and arthrography. She was treated by resection of the iliopsoas bursa and total prosthetic replacement of the hip joint. The pathogenesis is uncertain. In the literature, enlargement of the iliopsoas bursa with rheumatoid arthritis, osteoarthritis, pigmented villonodular synovitis, and synovial chondromatosis had been reported. Nevertheless, a correct preoperative diagnosis of the enlargement of the iliopsoas bursa is very difficult. MR imaging with enhanced Gadolinium-DTPA (Gd-DTPA) is proposed as the most useful examination for preoperative diagnosis.

    Notes: Abstract We examined the effect of pH on the extraction of urokinase-type plasminogen activator (u-PA) and plasminogen activator inhibitor-1 (PAI-1) from paranasal sinus mucous membrane associated with chronic sinusitis and antrochoanal polyps. The specific activity of u-PA extracted with buffer at pH 7.4 was stronger than that extracted with buffer at pH 4.2. The antigen level of u-PA extracted with the acidic buffer was significantly higher than that extracted with the neutral buffer. In contrast, the difference in antigen levels of PAI-1 extracted with the acidic buffer and neutral buffer was not significant. Based on these results, we inferred that the u-PA-PAI-1 complex was extracted by the acidic buffer and the activity of u-PA was therefore decreased.
