Changes in protein levels in perfusates of freely moving cats: relation to behavioral state.

Perfusates from the brains of freely moving cats, obtained by means of a push-pull cannula, contain high concentrations of proteins. The levels vary in a cyclic fashion and are higher during rapid eye movement sleep than during the waking state. The proteins represent a distinctive class of tissue protein and their changing levels appear to reflect an alteration in the protein content of the extracellular space of brain related to behavioral state.

Growth hormone effects on sleep and wakefulness in the rat.

The sleep-wakefulness pattern and brain protein levels were determined in rats for 3 h following these conditions: administration of an inhibitor of protein synthesis (anisomycin), administration of several doses of rat growth hormone (GH) or thyrotropin, and administration of a combination of anisomycin + GH or thyrotropin. Anisomycin inhibited sleep and increased wakefulness, GH increased REM sleep, and thyrotropin produced no change. The combined administration of GH and anisomycin returned sleep to control levels. Anisomycin produced a time-dependent decrease in brain protein levels, GH produced changes in brain protein levels as compared to controls in the second hour only, and thyrotropin had no effect upon brain protein levels. The results are discussed in terms of the possible relationship between sleep and proteins.
