The kinetic equation of non-Markovian type for description of the vacuum creation of parton-antiparton pairs under action of a space homogeneous time-dependent chromo-electric field of the arbitrary polarization is obtained on the strict non-per-tubative foundation in the framework of the oscillator representation. A comparison of the effectiveness of(More)
The review systematizes the latest data on the main mechanisms of realization of some pharmacological properties of ketamine which are particularly valuable in the treatment of many diseases and conditions. The authors present the main aspects of the ketamine effect on the central mechanisms of anesthesia and hemodynamics and give the characteristics of its(More)
The experiments on albino rats showed that clofeline administered in a subanalgesic dose significantly potentiates the analgesic effect of ketamine at the segmental and suprasegmental levels mainly through mu-opiate and partially through beta 2-adrenergic chains. The initiating role in potentiation belongs to the activation of alpha 2-adrenoreceptors. The(More)
The effect of hypophysectomy (HE) on pain thresholds was studied in female noninbred rats. Hyperalgesia was observed after HE since the first till the sixth day of the observation period. Droperidol (1 mg/kg i.p.) and amitryptyline (5 mg/kg i.p.) produced hyperalgesia in sham-operated rats, which was potentiated in hypophysectomized animals. In rats taken(More)
Painful and non-painful stresses have a different line of action on analgetic activity of phentanyl. Hyperalgetic action of immobilization stress is supposed to be linked with impairment of the functioning of the thalamocortical serotonin-sensitive system that gets activated before the development of maximal analgesia in non-stressed cats. Droperidol(More)
The authors carried out a quantitative assessment of pharmacodynamic effects of droperidol (5 and 25 mg/kg) and phentanyl (0.5 and 1 microgram/kg). The effects of the drugs on sensitivity and pain were studied by the "tail jerking" test. The electrophysiological studies included spectral analysis of the EG of the following central nervous system structures:(More)
