Abstract

Phagocytic cells constitute the organism's first line of defence against external aggression. These cells carry out their non-specific defence function through what is known as the phagocytic process. This can be split up into several stages: adherence, chemotaxis, attachment, ingestion and killing of the foreign agent. The influence of exercise on the phagocytic process is dependent on the step considered, but in general, different responses have been observed in the adherence and chemotaxis capacities depending both on the intensity of exercise and on the phagocyte (neutrophil or monocyte-macrophage) studied. However, with respect to the attachment and ingestion of antigen, exercise generally induces an increase in every "situation", independent of the intensity of physical activity and the involvement of neutrophils or macrophages. The results with regard to the microbicide capacity that have been obtained up to the present time are very contradictory, showing perhaps a greater dependence on the phagocyte studied and on the intensity of exercise. This fact may be due to different methods used in the studies. One could conclude that exercise stimulates certain stages of the phagocytic process. This stimulation could counterbalance the decreased lymphoid activity after certain types of exercise that some authors have reported.

3. Balneotherapy, Immune System, and Stress Response: A Hormetic Strategy?

Abstract

Balneotherapy is a clinically effective complementary approach in the treatment of low-grade inflammation- and stress-related pathologies. The biological mechanisms by which immersion in mineral-medicinal water and the application of mud alleviate symptoms of several pathologies are still not completely understood, but it is known that neuroendocrine and immunological responses—including both humoral and cell-mediated immunity—to balneotherapy are involved in these mechanisms of effectiveness; leading to anti-inflammatory, analgesic, antioxidant, chondroprotective, and anabolic effects together with neuroendocrine-immune regulation in different conditions. Hormesis can play a critical role in all these biological effects and mechanisms of effectiveness. The hormetic effects of balneotherapy can be related to non-specific factors such as heat—which induces the heat shock response, and therefore the synthesis and release of heat shock proteins—and also to specific biochemical components such as hydrogen sulfide (H₂S) in sulfurous water and radon in radioactive water. Results from several investigations suggest that the beneficial effects of balneotherapy and hydrotherapy are consistent with the concept of hormesis, and thus support a role for hormesis in hydrothermal treatments.

Abstract

Flow cytometer measurements were made of the basal variations in peripheral blood functional monocytes and granulocytes over the course of a training season (January to November) of a cycling team. Parallel determinations were made of plasma concentration of catecholamines (chromatography) and cortisol (RIA) in a search for neuroendocrine markers. The results showed the greatest phagocytic capacity to occur in the central months (March, May, and July), coinciding with the greatest number and highest level of competitive events with good correlation with a peak in epinephrine during these months (r(2) = 0.998 for monocytes and r(2) = 0.674 for granulocytes). No good correlations were found between phagocytosis and norepinephrine or cortisol. The highest values for phagocytosis and epinephrine concentration were found in May. These results suggest that blood epinephrine concentration could be a good neuroendocrine marker of sportspeople's phagocytic response.
