PURPOSE To investigate the potential of diffusion tensor imaging (DTI) parameters as in-vivo biomarkers of axon and myelin sheath integrity of the median nerve in the carpal tunnel as validated by correlation with electrophysiology. METHODS MRI examinations at 3T including DTI were conducted on wrists in 30 healthy subjects. After manual segmentation of the median nerve quantitative analysis ...

Poly(ADP-ribose) polymerase (PARP) activation has been implicated in the pathogenesis of diabetic complications, including nephropathy and peripheral neuropathy. This study aimed at evaluating the manifestations of both complications in diabetic Akita mice, a model of Type 1 (insulin-dependent) diabetes, and their amenability to treatment with the potent PARP inhibitor, 10-(4-methyl-piperazin-1...

Aim: To investigate the effect of normalizing vitamin B12 (B12) levels with oral (methylcobalamin) 1000 ?g/day for one year in patients diabetic neuropathy (DN). Patients and methods: In this prospective, double-blind, placebo-controlled trial, 90 type 2 diabetes on metformin at least four years both peripheral autonomic DN were randomized to an active treatment group (n = 44) receiving a contr...

Certain functions of the nervous system were examined in 31 printing workers (mean age 44) exposed to trichloroethene (mean duration 16 years) and 28 controls (mean age 45). In the sural nerve the conduction velocity (SNCV), response amplitude, and refractory period (SRP) were measured. The latencies of the masseter and the blink reflex were determined to test the trigeminal nerve. In the peron...

UNLABELLED Sensory nerve conduction velocity (SNCV) of median nerve measured across the carpal tunnel, difference between distal sensory latencies (DSLs) of median and ulnar nerves and difference between distal motor latencies (DMLs) of median and ulnar nerves are commonly used nerve conduction parameters for diagnosis of carpal tunnel syndrome (CTS). These are having high degree of sensitivity...

Relief from painful diabetic neuropathy is an important clinical issue. We have previously shown that the transplantation of cultured endothelial progenitor cells or mesenchymal stem cells ameliorated diabetic neuropathy in rats. In this study, we investigated whether transplantation of freshly isolated bone marrow-derived mononuclear cells (BM-MNCs) alleviates neuropathic pain in the early sta...

Motor and/or sensory conduction velocities are used to assess peripheral nervous system disorders. Although the miniature pig represents a model of choice for long-term pharmacological experimentation, no study has so far been reported on this model in relation to the measurement of nerve conduction velocities. We developed the present technique and applied it to 34 3-18-month-old Yucatan minip...

OBJECTIVE To examine whether the neuropathological and metabolic changes of peripheral nerves are correlated to clinical features in diabetes mellitus type 2 patients with peripheral neuropathy. METHODS 147 type 2 diabetic patients with signs/symptoms of diabetic peripheralneuropathy (DPN) aged 53.4 ± 12.3 years and 134 healthy volunteers aged 55.5 ± 11.7 years were investigated for fasting p...

AIMS To compare the efficacy and safety of daily lipoic acid (300-600 mg i.v.) plus methylcobalamin (500-1000 mg i.v. or im.) (LA-MC) with that of methylcobalamin alone (MC) on diabetic peripheral neuropathy (DPN). METHODS Electronic database were searched for studies published up to November 1, 2012 and study quality was assessed in duplicate. A random or a fixed effect model was used to ana...

objective: the aim of present study was to evaluate the effects of oral administration of gallic acid (ga) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. materials and methods: seventy adult male wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) control (cont), 2) cru...
