For the evaluation of peripheral neuropathies, physicians traditionally relied primarily on information gained from an accurate clinical history, a thorough physical examination, and electrodiagnostic testing with electromyography, nerve conduction studies, and recordings of somatosensory evoked potentials (1,2).

We used a two-chamber culture model with human fetal DRG cultivated in an inner chamber, allowing axons to grow out and penetrate an agarose barrier and interact with autologous epidermal cells in the outer chamber. Proposed molecular modalities in neuropathic pain include ion channel expressions, immune reactions, and inflammatory substrate diffusions. MATERIALS AND METHODS: Electrophysiological, fluorescence optical, and volume measurements were made to determine the effect of nucleoside analogs on the swelling-dependent chloride current (ICl) in NIH 3T3 fibroblasts and in human T cell lymphoma (H9) cells and the cAMP-dependent chloride current in CaCo cells. Seroconversion was more common in women, and was associated with African American race, heterosexual identity and longer duration as IDU. When cultures were continuously incubated with lead and heme together for 6 wk, the segmental demyelination seen in cultures treated with lead alone did not occur.
