Tuberculous osteomyelitis in the ulna of a patient undergoing hemodialysis.

A 76-year-old woman on hemodialysis (HD) presented with pain and swelling in the left wrist and forearm. The osteomyelitis occurred in the part of the ulna adjacent to the arteriovenous fistula. Mycobacterium tuberculosis was identified in pus obtained from the left forearm, leading to a diagnosis of tuberculous osteomyelitis.

Renal synthesis of urokinase type-plasminogen activator, its receptor, and plasminogen activator inhibitor-1 in diabetic nephropathy in rats: modulation by angiotensin-converting-enzyme inhibitor.

Plasmin is an important factor in the degradation of extracellular matrix. In the study reported here we examined the expression of plasminogen-activator inhibitor-1 (PAI-1), urokinase-type plasminogen activator (uPA), and uPA receptor (uPAR), as well as the relevance of such expression to the production of type IV collagen, a major component of extracellular matrix, in the renal tissue of rats with streptozotocin-induced diabetes. Because angiotensin II is involved in the synthesis of PAI-1 and uPA, we also examined the effect of benazepril, an angiotensin-converting-enzyme inhibitor, on the expression of PAI-1, uPA, and uPAR messenger RNAs (mRNAs) and type IV collagen protein.
