The number statistics of diabetic neuropathic pain was analyzed after intravenous STZ rats in various time courses. 40% and 78% correspond to the average pain threshold at the+ first week minus or plus the SD of Von Frey test, respectively. Similarly, 5.9 s (second) and 8 s correspond to the average pain threshold at the first week minus or plus the SD of the Hargreaves test. deviation.
