Abstract
Modeling of neurogenic pain syndrome by sciatic nerve transection in rats with pronounced dopamine-deficiency-dependent 1-methyl-4-phenyl-1,2,3,6,-tetrahydropyridine-induced experimental depressive syndrome forms a stable state of combined pain and depression, which can be considered as a model of the pain-depressive syndrome. The neurogenic pain syndrome prolongs the state of behavioral depression in rats irrespective of their initial anxiety level. The depressive symptoms can potentiate the severity of pain syndrome. By a number of indices, more pronounced behavioral changes during the development of pain-depressive syndrome occur in initially nonanxious rats.
