الملخص EN

In Sudan (Khartoum state), the material was collected during the winter and summer seasons .The aim of the work to show the steroid histochemical of the adrenal gland of adult Sudanese chicken (Gallus domesticus) and duck (Anas platyrhynchos) .The adrenal glands were two small organs, irregularly oval and pale yellow in the colour (Ghosh et.al.2001 and Sarker et.al.2014).The histochemical localization of steroid enzymes was studied in the adrenal gland of adult chicken and duck.

Δ 5 -3β hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase were demonstrated solely in the cortex.
