title: Serial changes of sensory nerve conduction velocity and minimal F-wave latency in streptozotocin-induced diabetic rats.
abstract: We studied the serial changes of sensory nerve conduction velocity (SNCV) in the caudal nerve of streptozotocin (STZ)-induced diabetic rats using a new technical method. Minimal F-wave latency was also studied by stimulating the tibial nerve. The SNCV in the diabetic rats was slower than that in the normal rats 2 weeks after STZ injection, and minimal F-wave latency was prolonged compared to normal rats 4 weeks after STZ injection. Treatment of the diabetic rats with insulin for 14 days inhibited SNCV slowing and minimal F-wave latency prolongation. This new method to measure SNCV is useful for various studies, and improvement of diabetic neuropathy with insulin treatment is indicated by recovery from SNCV slowing and minimal F-wave latency prolongation.
