Effects of nitrous oxide exposure on Met-enkephalin levels in discrete areas of rat brain
Morris, B.; Livingston, A., 1984: Effects of nitrous oxide exposure on Met-enkephalin levels in discrete areas of rat brain. Neuroscience Letters 45(1): 11-14
Rat were exposed to 80% nitrous oxide in oxygen for 1 and 18 h. Met-enkephalin levels in the dorsal raphé, medial thalamus, periaqueductal grey, raphé magnus and locus coeruleus were measured by radioimmunoassay in control and treated animals. There was no change in Met-enkephalin levels at either time point in any of the brain areas examined.
