Unpredictable cold-immobilization stress effects on voluntary ethanol consumption in rats.

abstract：AIMS:Brain injuries based on their causes are divided into two categories, TBI and NTBI. TBI is caused by damages such as head injury, but non-physical injury causes NTBI. Prolactin is one of the blood factors that increase during brain injury. It has been assumed to play a regenerative role in post-injury recovery. M...
