Combined pain and depression status in rats was created by inducing experimental depressive syndrome (by subchronic injection of MPTP proneurotoxin) in animals with manifest and developing neurogenic pain syndrome induced by preliminary crossing of the sciatic nerve in the hind limb. The neurogenic pain syndrome augmented by some parameters the depressive(More)
Electrophysiological experiments on Wistar rats demonstrated that prior immunization of animals with conjugates of dopamine and serotonin with bovine serum albumin, as well as with bovine serum albumin alone, played a partial protective role in relation to the subsequent development in these animals of experimental MPTP-induced depressive syndrome:(More)
In electrophysiological experiments in Wistar rats it was shown that preventive immunization of animals with bovine serum albumin conjugated with dopamine or 5-hydroxytryptamine or with bovine serum albumin alone partly protects against the development of experimental MPTP-induced depressive syndrome. Signs of depressive-like state such as decrease in(More)
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(More)
The levels of anxiety were determined in male Wistar rats using a complex multiparameter method for evaluating anxiety-phobic states in rats based on ranged scale. The effects of psychotropic drugs differed in rats with innate high and low levels of anxiety. Anxiolytics sodium valproate (200 mg/kg), phenazepam (0.05 mg/kg) and diazepam (0.1 and 0.6 mg/kg)(More)
Bilateral destruction of the Locus coeruleus in rats was carried out by means of 6-hydroxydopamine injections. Sham-operated animals served as control ones. Electrical activity was recorded in the region of the Locus coeruleus, the dorsal hippocampus, and in the caudatus-putamen complex. Beginning from the second week after surgery in experimental rats was(More)
A new multiparameter method for evaluating anxiety-phobic states in rats is elaborated. The method is based on the ranged scale consisting of parameters which characterize the species-specific rat response to the series of ethologically adequate test-stimuli inducing manifestation of the anxiety-phobic states. The method makes it possible to evaluate(More)
The injection of subconvulsive doses of pentylenetetrazol (corazol, 10 mg/kg, intraperitoneally) leads to the appearance of a complex of the emotional-behavioral disturbances in rats which consists of three main syndromes: anxiety, pathologically enhanced fear and inactivation state. Each of syndromes is characterized, by a particular pattern of electrical(More)
Microinjections of kainic acid and ferrous sulfate into basomedial nuclei of both amygdalae resulted in the formation of the generator of pathologically enhanced excitation (GPEE), as evidenced by the epileptical activity (EpA) registered in both nuclei. EpA of different intensity and pattern could be retained for more than three weeks. Hyperactive(More)
Purified tetanus toxin (TT) (80-800 Dlm/mg protein) releases both endogenous and exogenous (14)C-norepinephrine from the isolated nerve endings (synaptosomes) of the rat brain. Within the investigated range of concentrations TT does not suppress norepinephrine release induced by different ways of depolarizing the synaptosomes in vitro.
