– AFFECTING THE CARBOHYDRATE METABOLISM
glucocorticosteroids
233
-AFFECTING THE MINERAL METABOLISM
mineralocorticosteroids
234
CONTROLLED BY CORTICOTROPIN RELEASED FROM THE PITUITARY GLAND AS A RESPONSE TO STRESS; IT IS BOUND TO THE ADRENOCORTICAL CELL MEMBRANE, STIMULATES THE PRODUCTION OF CAMP, TRIGGERING THE DELIVERY OF CHOLESTEROL ESTERS FOR THE SYNTHESIS OF GLUCOCORTICOIDS; THEY INHIBIT THE CORTICOTROPIN (NEGATIVE FEED-BACK MECHANISM)
clucocorticoids
235
glucocorticoids are transported in the plasma by what protein
transcortin
236
TARGETS: LIVER, KIDNEY, LYMPHOID TISSUE (SPLEEN, LYMPH NODES, LYMPHOID PLAQUES IN THE INTESTIN, LYMPHOCYTES, THYMUS), CONNECTIVE TISSUE (BONES, SUBCUTANEOUS TISSUE, ADIPOSE TISSUE) MUSCLE
glucocorticoids
237
IN THE BLOOD: GLUCOSE, FATTY ACIDS, GLYCEROL, AMINOACIDS, KETONE BODIES↑ – IN URINE: GLUCOSE, AMINOACIDS, KETONE BODIES↑ – IN THE KIDNEYS: ↑ NA+ REABSORPTION, K+ EXCRETION; what hormone
glucocorticoid
238
NA AND H2O ARE RETAINED IN EXTRACELLULAR SPACE (EDEMA) what hormone
glucocorticoid
239
– IN BONES: ↓ PROTEIN SYNTHESIS, DEOSSIFICATION, CA AND P →BLOOD →URINE what hormone
glucocorticoid
240
SECRETION IS CONTROLED BY NA+ AND K+ (STIMULATED BY LOW NA+ AND HIGH K+ CONCENTRATION)
aldosterone
241
T IS BELIEVED THAT THE EPIPHYSIS PRODUCES A TROPIC HORMONE = ______ THAT STIMULATES THE SECRETION of aldosterone
adrenoglomerulotropin

konn's disease
248
hypofunction of corticotropin

249
: REDUCED RESISTANCE TO EMOTIONAL STRESS AND INFECTIONS, CHEMICAL, MECHANICAL FACTORS; IT DETERMINES HYPOGLYCEMIA
glucocorticoid deficiency
250
DISTURBED WATER-SALT IMBALANCE - LOSS OF NA+, H2O AND ACCUMULATION OF K+ → HYPOTENSION, MYASTENIA, PROGRESSIVE FATIGABILITY, LOW MUSCULAR EXCITABILIT
aldosterone deficiency

PRACTICAL USE OF CORTICOSTEROIDS
TREATMENT OF ALLERGIC AND AUTOIMMUNE DISEASES: RHEUMATISM, COLLAGENOSES, NONSPECIFIC ARTHRITES, BRONCHIAL ASTMA, DERMATOSES DESENSITIZING ANTIINFLAMMATORY IMMUNODEPRESSIVE AGENTS (PROPHYLAXIS OF REJECTION OF TRANSPLANTED ORGANS)
