5.7 Glucocorticoides.

5.7.1 Acción.

1. the blood glucose :

-antagonizing the secretion and actions of insulin.

-gluconeogenesis.

2. Protein:

-mainly catabolic

•METABOLISM

3. Liver:

-stimulate the synthesis of certain enzymes

4. regulate fatty acid mobilization by enhancing the activation of cellular lipase

•METABOLISM

•Leukocytosis.

•depletion of circulating eosinophils.

•inhibit the production and action of the mediators of inflammation:lymphokines and prostaglandins.

•inhibit the production and action of interferon by T lymphocytes and the production of IL-1 and IL-6 by macrophages

•inhibit the production of T cell growth factor (IL-2) by T lymphocytes.

•Reverse macrophage activation and antagonize the action of migration-inhibiting factor (MIF).

•Reduce prostaglandin and leukotriene production by inhibiting the activity of phospholipase A2.

•inhibit the production and inflammatory effects of bradykinin, platelet-activating factor, and serotonin

5.8 Mineralcorticoides.

5.8.1 Efectos en epitelio

5.8.2 Efectos sobre células no epiteliales

1. They do not modify sodium-potassium homeostasis.

2. Aldosterone modifies the expression of several collagen genes and/or genes controlling tissue growth factors.

3. Some effects on nonepithelial cells may be via nongenomic mechanisms.

4. Some of these tissues—the myocardium and vasculature—may also produce aldosterone, although this theory is controversial.

•Baja intensidad débil de la cortisolemia.

•> 60% PAM de la cortisolemia tanto mayor cuanto mayor es la intensidad del trabajo.

•Mayor de la cortisolemia cuanto mas depleccionado esté el glucógeno.

•Lesión con dolor agudo de la cortisolemia.

de la cortisolemia tanto en ejercicios estáticos como dinámicos.
