Objective To explore expression of endogenous ouabain(EO) in multiple adrenal tumors.Methods Thirty-one cases of adrenal tumors and 6 cases of healthy adrenal tissues were selected. The expression of EO in the adrenal tiss ue was detected with immunohistochemical streptavidin peroxadase conjugated(SP) method.Results Most of EO positive products were localized in cy toplasm of the zona reticularis of human adrenal cortex, and positive products s howed to be fine granular. There was no positive signal in the medulla. EO showe d on diffused positive in patients with pheochromocytoma accompanied high blood pressure[SBP(165.22±7.61) mmHg, DBP(105.52±4.26) mmHg], but there were neg ative in ones with normative blood pressure[SBP(118.52±4.58) mmHg, DBP(83±3.60) m mHg]. The expression of EO was positive in all adrenocortical hyperplasic, aden oma an d carcinoma, no matter its high or normative blood pressure. The degree of expre ssion of EO in adrenal tissues was related to the level of BP.Conclusion Expression of endogenous ouabain(EO) in health y adrenal tissue and adrenal tumors was a valuable morphological and pathophysio logical clue for the research on ouabain.
