[Influence of food biologically active supplements on the immune status of healthy volunteers].

The authors show that use of biologically active additions to food Bio-Normalizer, Oxine, Gonsyn and Lovsin is effective method of immune correction of human functional state. These biologically active additions to food lead to increase 15-25 per cent of T-helper activity, activates 20-32 per cent of B-component of immune system, enhance of immunocompetent cells cooperation and rise human antibacterial resistance. That all optimizes immune response and increases resistance to extreme impacts.

[Relationship of insulin dependent metabolic disorders to efficiency of intensive operator's work]. / Vzaimosviaz' insulinozavisimykh metabolicheskikh narushenii i kachestva napriazhennoi operatorskoi deiatel'nosti.

The purpose was to state correlation between insulin-dependent metabolic disorders and efficiency of intensive operator's work. The investigation included 12-hr mission on a flight simulator performed by 50 normal (aged 23-36) flight-qualified pilots. Increase in the number of erroneous actions was in direct correlation with insulin (r = 0.74, p < 0.01) and in reverse correlation with glucose incretion (r = -0.594, p < 0.01) and STH (r = -0.90, p < 0.006). Metabolic tests (glucose and insulin) showed that psychoemotional loading due to the intensive operator's duties led to early fatigue and sharp straining of tissue structures in people with dysregulatory disorders in insulin metabolism. The psychoemotional loading may also provoke dysregulatory disorders and development of insulin-dependent disturbances.

[Individual characteristics of changes in the functional state of a human operator in a simulated long-term flight aboard a single-seat airplane]. / Individual'nye osobennosti izmeneniia funktsional'nogo sostoianiia cheloveka-operatora v usloviiakh modeliruemogo dlitel'nogo poleta na odnomestnom samolete.

In the 12-hour experiment with simulation of habituation factors in the cabin of one-seat aeroplane the individual dynamics of indices in 29 men (volunteers) has been studied. The reactive-situational anxiety, self-rating, heart rate, arterial pressure, blood glucose level, operator working capacity have been recorded. There have been revealed the twelve types of individual dynamics of the indices: linear increase or decrease, elevation or decline with stabilization of an indicator level, stable with a consequent elevation (decline), step-wise increase (decrease), P- and U-shaped wave-shaped dynamics and practically constant level have been recorded. The individual dynamics was depended on the expressivity and plasticity (responsiveness) of the prestart response to the effect of unfavourable factors resulting in the psychic and physiological stress and fatigue as well as in the internal variations of each test subject.

[Problems in the use of alimentary agents to enhance body's resistance of flight personnel to unfavorable occupational factors]. / Problema ispol'zovaniia alimentarnykh sredstv dlia povysheniia ustoichivosti organizma letnogo sostava k vozdeistviiu neblagopriiatnykh faktorov professional'noi deiatel'nosti.

The main directions in the use of nutrients to enhance human resistance to unfavorable occupational factors in order to promote flying health and longevity are considered. The prime tasks of each direction are analyzed and the ways of their solution are identified by taking into account the available approaches.
