Nitric oxide in cerebrospinal fluid and local inducible nitric oxide synthase after cauda equina compression in rats.

We investigated the time course of changes in nitric oxide metabolite (NO2− plus NO3−: NOx) levels in the cerebrospinal fluid and the expression of local inducible nitric oxide synthase following cauda equina compression in rats. Cerebrospinal fluid NOx levels were significantly increased from 12 h
