Stress reactions

Stress reaction—fail to activate due to high stress experienced in scenario. 

Within the nervous system, ChEs were shown to be involved in membrane conductance and transmission of excitatory amino acids, learning and memory, neurite growth, neuritic translocation and acute stress reactions. Recent findings propose AChE s involvement in apoptosome formation [2].

FIGURE BO-2 Wallerian degeneration in the PNS. After an axon is injured, resulting chromatolysis, i.e. stress reaction and increased protein synthesis, occurs in the neuronal cell body, with axonal and myelin degeneration distal to the injury. Growth-permissive Schwann cells secrete growth factors that stimulate axons to regenerate. 

An example for stimulus generalization are responses of rats to stress-inducing odors. Laboratoiy rats of the Wistar strain respond to predator odors, specifically mercapto compounds in fox droppings, with stress reactions, for example avoidance behavior such as freezing and increased plasma corticosterone concentrations (Vemet-Mauiy et ah, 1984). The rats were trained to avoid water scented with a mercapto odorant that contained both a keto- and a sulfhydryl group (4-mercapto-4-methyl-2-pentanone). As the animals licked a waterspout, a mild electric shock was applied to their tongue. When different compounds were tested thereafter, the rats avoided compounds with similar...

Acute stress When symptoms are associated with acute stress reactions, treatment with methylphenidate usually is not indicated. 

According to prevailing concepts, stress is being experienced when an individual is confronted with a situation that is appraised as personally threatening and for which adequate coping resources are unavailable (Lazarus, 1985). Biological stress reactions are particularly elicited during novel, uncertain, and unpredictable situations (Mason, 1968). These concepts emphasize that individual perception and behavioral adaptations to an event are critical to the experience of stress. In addition, physical stimuli, such as injury. 

Saxe and colleagues (1997) have developed the Child Stress Reaction Checklist, which is a 30-item, Likert-scale parent interview that assesses children s PTSD symptoms across the major symptom domains.

Under normal conditions a stress reaction is shut off once the stimulus, e.g. an enemy or some other situation perceived as dangerous, has disappeared. If. however, due to any possible reason, the level of cortisol is not decreasing to its baseline level, one speaks of a hypercortisolemic state that, if chronified, can cause harm to an organism and ultimately may lead to physiological damage. Many chronically anxious or depressed patients are in a hypercortisolemic state. 

A few fire departments include a polygraph, or lie detector test, as part of the background investigation. As long as you have been honest in what you have said when your stress reactions weren t being monitored by a polygraph machine, a lie detector test is nothing to worry about.

However, one is bound to wonder whether this was a direct reaction to levonorgestrel or a stress reaction to the absence of menstrual periods. Like many other users of Mirena, this woman had amenorrhea associated with facial flushing and pustules conditions such as urticaria, eczema, pompholyx, and erythema multiforme occur cyclically in some women in the second half of the menstrual cycle, irrespective of contraceptive use.

FIGURE 13.3 Oxidation of MPTP to l-methyl-4-phenyl-2,3-dihydropyridium ion (MPDP+), and finally to MPP+ generates free radicals and causes parkinsonism in humans. A deficiency of NADK Co (complex I) also causes striatal cell death. A deficiency of complex I may signify that an MPTP-like neurotoxin is generated endogenously, enhancing the vulnerability of striatum to oxidative stress reactions.

BZDs such as chlordiazepoxide (Librium) or diazepam (Valium) may be prescribed to treat anxiety, seizures, acute stress reactions, and panic attacks, or to alleviate the side effects of drug or alcohol withdrawal. Those BZDs with a more sedating effect, such as estazo-lam (ProSom) or triazolam (Halcion), may be prescribed for short-term treatment of sleep disorders. However, the newer generation of non-BZD agents—zolpidem (Ambi-en) and (Sonata)—are less potentially addictive hypnotic drugs than the BZDs.
