Abstract: | 5 alpha-Dihydrocortisol (11 beta, 17, 21-trihydroxy-5 alpha-pregnane-3,20-dione), 5 alpha-dihydrocorticosterone (11 beta, 21-dihydroxy-5 alpha-pregnane-3,20-dione) as well as cortisol (11 beta, 17, 21-trihydroxy-4-pregnene-3,20-dione) and corticosterone (11 beta, 21-dihydroxy-4-pregnene-3,20-dione) were administered for seven days to male rats. Blood glucose increased in cortisol- and corticosterone-treated rats and blood insulin decreased after 5 alpha-dihydrocorticosteroid treatment. In the liver, total protein was elevated after cortisol, corticosterone and 5 alpha-dihydrocorticosterone application. Phosphoenolpyruvate carboxykinase and fructose-1,6-diphosphatase activities in liver were significantly lowered after treatment with 5 alpha-dihydrocortisol and 5 alpha-dihydrocorticosterone. |
