lysyl-glutamyl-aspartic-acid and Mental-Disorders

This study was designed to estimate the neurobehavioral status and to compare the prevalence of psychoadaptive disorders among lorry-drivers (experimental group) and metal craftsmen (control group) in connection with their age, length of service, occupational hazards, work schedule and sociodemographic characteristics. 150 male lorry-drivers (mean age 43.3 +/- 0.9) and 150 male metal craftsmen (mean age 42.8 +/- 0.9) were examined using a clinical questionnaire to identify, estimate and compare neurotic states. The study comprised 3 groups: 1st--subjects with stable psychic adaptation, 2nd--subjects with unstable psychic adaptation, a risk group, 3rd--subjects with stable psychic disadaptation, i.e. with some borderline mental disorders (BMD). Significant differences in the prevalence of psychic adaptation and disadaptation among groups under study were found. The predominance of the 2nd and 3rd groups among lorry-drivers in comparison with control group was found. The results showed that social and demographic characteristics had no significant influence neither in experimental nor in control groups (p > 0.1). Variability of psychoemotional imbalance levels among lorry-drivers was found to be due to a combination of the following factors: occupational exposure and their work schedule, while in control group--to the age of metal craftsmen. Comparative analysis of neurobehavioral disorders revealed the predominance of the asthenic symptoms, anxious and depressive manifestations, hysterical reactions among lorry-drivers, and the vegetative disorders only in control group. The results thus obtained support the hypothesis of occupational hazards and long driving experience being the risk factors for the development of BMD. The application of bioregulating peptides was found to restore the organism adaptive potential, improved psychoemotional indices, intensified resistance to work stress and reduced occupational risk of borderline mental disorders (p < 0.001-0.05). The best effect was obtained in case of combined application of several cytogens (pinealon and vezugen), which were optimally selected regarding the effect of each adverse occupational factor on a target organ or system. The employed parameters of psychoemotional state were rather informative for assessing the peptidergic properties of cytogens in occupational medicine and geriatrics.
