We examined whether the short-term beneficial effects of nerve growth factor (NGF) upon regeneration are sustained over a prolonged period of time across 8-mm gaps within silicone chambers. Rat sciatic nerve regeneration both with and without NGF was examined after 10 weeks. Myelinated counts from the regenerated sciatic and distal tributary nerves were… (More)
The ability of extracellular proteins to influence the regenerative process was examined in Sprague-Dawley rats. Silicon chambers, filled with sterile saline solutions of cytochrome-c, fibronectin, laminin, a combination of fibronectin and laminin, or nerve growth factor were surgically implanted between the severed ends of sciatic nerves to form gaps of 18… (More)
Compared with normal or denervated human muscle, long chain acyl CoA was increased in muscle from patients with Duchenne dystrophy. Free and short chain acylcarnitine were reduced in Duchenne muscle, whereas long chain acylcarnitine was preserved. The accumulation of long chain fatty acid derivatives may imply disruption of fatty acid oxidation.
The silicone chamber model was used to evaluate peripheral nerve regeneration (PNR) in streptozocin (STZ)-induced diabetic rats. Diabetic and control animals underwent sciatic nerve transection and silicone chamber implantation establishing gaps of various lengths between the transected nerve ends. In animals with 5 and 10 mm gaps, diabetes was induced in… (More)
Two sisters with progressive myopathy demonstrated microscopic and biochemical evidence of lipid storage in skeletal muscle. Their muscle biopsy specimens resembled those seen in Duchenne's muscular dystrophy and some of the biochemical features were similar, including increased muscle concentration of long-chain acyl-coenzyme A (a fatty oxidation… (More)
