Abstract
A study has been made regarding the action of the hydrocortisone, testosterone and 17β-estradiol on isolated liver and spleen tissue homogenates or slices of male and female adults of the fish Trachurus mediterraneus ponticus. The results showed a decrease of the oxygen uptake and of the cytochrome oxydase and succinic dehydrogenase activity of the liver homogenate after hydrocortisone administration, while this hormone increased significantly the lactic acid production in both tissues. Testosterone acted in an opposite manner to hydrocortisone by increasing the intensity of oxygen consumption and the succinic dehydrogenase activity, but decreased the lactic acid production of the liver and spleen tissue preparations. Estradiol decreased the oxygen consumption of the liver, the cytochrome oxydase activity and the lactic acid production in both tissues of female Trachurus mediterraneus ponticus.
Résumé
-
1.
On a étudié l'action directe de l'hydrocortisone, de la testostérone et de l'estradiol sur l'activité de la succinedèshydrogénase (SDH) et de la cytochromeoxydase (CyOx), sur la consommation de l'oxygène et sur la production de l'acide lactique et pyruvique par les coupes tissulaires du foie et de la rate chez le chinchard (Trachurus meditarraneus ponticus).
-
2.
L'hydrocortisone en concentration de 10-4 M, diminue la consommation d'oxygène et l'activité de la CyOx et de la SDH. Cette hormone augmente fortement la production de l'acide lactique par les coupes tissulaires du foie et de la rate.
-
3.
La testostérone détermine une diminution de la production de l'acide lactique, et augmente l'activité de la SDH et la consommation de l'oxygène.
-
4.
L'estradiol diminue l'activité de la CyOx du foie et la production de l'acide lactique.
-
5.
On peut conclure que pour les oxydations intracellulaires et la glycolyse dans le foie et la rate du chinchard, l'hydrocortisone est un antagoniste de la testostérone et de l'estradiol.
