ANALYSIS OF THE ROLE OF CENTRAL CHOLINOREACTIVITY IN EXPERIMENTAL TRAUMATIC BRAIN INJURY
Abstract
The aim of the research. To study effects of activation and inhibition of the central cholinergic systems (CCS) in traumatic brain injury (TBI).
Studied problem. To investigate the influence of the reactivity of the central cholinergic systems on the course of the acute period of traumatic brain injury, in an acute experiment on laboratory animals in vivo.
The main scientific results. It was found that in the acute period of TBI (the first three days), both activation and blockade of CCS led to a decrease in mortality, which was statistically confirmed only for their activation. The control group was characterized by the progression of neurological deficit, which was realized due to motor disorders and reflex sphere. Upon activation of the CCS, the degree of neurological deficit was significantly less than in other groups, but, nevertheless, it increased from 48 hours after the injury, as regards behavioral and consciousness disorders. Inhibition of cholinergic systems led to a sharp increase in neurological deficit in all areas immediately after injury, to a greater extent due to reflex disorders. This, together with a high mortality rate, indicated a negative effect of the pharmacological shutdown of CCS in TBI.
The area of practical use of the research results. The obtained results will allow a deeper study of the influence of the central cholinergic systems on the course and descent of TBI. To develop effective methods of pharmacological correction in the treatment of patients in the acute period of TBI.
Innovative technological product: pathogenetically substantiated medical treatment of the acute period of traumatic brain injury, development of new methods of pharmacological neuroprotection for persons with a priori high risk of injury, development of effective options for reducing mortality and disability from TBI.
Scope of the innovative technological product. The important role of CCS in the realization of the response of the central nervous system to TBI was established, and the possibility of using pharmacological stimulation of the central nervous system with cholinomimetics of the central type of action was justified.
