[Morphofunctional features of lymph nodes, thyroid gland and testis of rats during adaptation reactions to stress and activation].

The morphofunctional state of lymphatic nodes, thyroid gland and testis have been studied with morphometric, cell photometric and biochemical methods in experiments on adult white rats under the influence of nonspecific adaptation stress and activation reactions caused by small doses of adrenaline (125 mg/kg and 5 mg/kg). The research showed that the changes in the structure and function of the lymphatic organs under stress and activation were markedly different. If stress results in depression of functional state of these organs, the activation reaction, on the contrary, stimulates it.

Reestablishing health: factors influencing the child's recovery in pediatric intensive care.

This article presents a conceptual framework that examines five factors affecting the rate of recovery and return to health for critically ill children in pediatric intensive care. Stress, coping, development, social support, and immunocompetence are analyzed from a biopsychosocial perspective to gain a clearer understanding of how these variables interrelate to affect the child's ability to recover. The conceptual framework will assist the nurse in recognizing which children are at greatest risk for setbacks and delays in recovery.

[Enkephalinergic transmission: functional characteristics and physiologic role].

Enkephalins are small CNS opioid peptides present in the CNS and the physiological importance of which is well accepted. Their effects at a cellular level and recent acquisitions on their physiological significance are reviewed with a particular mention to the interaction with other neurotransmitters, especially GABA. The role of enkephalins in sensory, motor and vegetative processes is reviewed. Some developments of particular interest are proposed, e.g. the role of enkephalins in memory, or their relations with the immune system. The methodological problems concerning the study of these peptides and the limits of a clinical approach are briefly discussed.

[Stress and the endogenous opioid system. II. Stress, stress models and endogenous opioid peptides].

Biochemical and pharmacological findings indicate an activation of the opioid system under certain stress influences. In this paper findings are discussed, according to which the activation of the opioid system depends on the temporary distribution pattern and the kind of the stressor. In response to stress opioid peptides are involved in excitatory and inhibitory processes. The participation of different types of opioids in central and peripheral stress-induced effects is discussed. Some findings suggest that beta-endorphin acts mainly centrally rather than peripherally, whereas the enkephalins take part in peripheral regulatory processes (gastrointestinal system, adrenal glands). Now there is evidence that the endogenous opioids modulate stress-induced effects, but there has been much controversy on how this fact should be established. These controversies mainly resulted from the many factors that influence activation.
