The Effect of Surgical Procedure in the Nasal Cavity on the Passive Avoidance Conditioning and the Hypothalamic Level of Monoamines in Rats.

A rat biological model of septoplasty was used to study the effect of surgery on passive avoidance conditioning (PAC). Septoplasty was shown to increase anxiety and to reduce exploratory activity in rodents during PAC. A neurochemical analysis of the hypothalamus was carried out immediately after the end of the experiment and showed an increase in norepinephrine (NE) metabolism after septoplasty. The finding was tentatively associated with activation of the hypothalamic-pituitary-adrenal axis.

Comparison of the Effect on Heart Rate Variability for Modeling Septoplasty and Modeling Deprivation of the Olfactory Analyzer in Rats.

Modeling septoplasty and modeling sensory deprivation of the olfactory analyzer in rats were compared for the effect on the frequency domain of heart rate variability (HRV). Bulbectomy provoked more pronounced changes in HRV as compared with septoplasty simulation.

[Cerebrospinal fluid lactate and peroxide compounds in young children with craniocerebral trauma]. / Issledovanie laktata i perekisnykh soedinenii likvora u detei rannego vozrasta pri cherepno-mozgovoi travme.

The content of lactate and products of lipid peroxidation in the c. s. f. of infants with craniocerebral trauma was studied. The content of lactate and malonic dialdehyde in the c. s. f. was significantly increased, which correlated with the severity of the trauma. The results of the study make it possible to followup the course of the cerebral traumatic disease and the efficacy of the applied therapy and also may severe as prognostic criteria in evaluating the possible sequelae of the craniocerebral trauma.

[Ultrasonography of the brain in children with craniocerebral trauma]. / Ul'trasonografiia mozga u detei pri cherepno-mozgovoi travme.

The authors examined 275 children with acute craniocerebral trauma (CCT). Various types of intracranial hemorrhages and contusions of the brain were differentiated by means of ultrasonography (USG). Analysis of complex examination of children with CCT allows the conclusion that USG is a highly informative diagnostic method, particularly in infancy, which makes it possible to visualize the craniocerebral injuries and study them continuously during treatment. Intraoperative USG was conducted in older children with suspected intracranial hematoma, which allowed the pathological process to be clearly located.
