TABLE 1.

Steroids tested for endozepine production

The concentration of steroids necessary to induce production of 80 pmol of endozepine/mg of protein is indicated. Weak induction corresponds to production of 8 pmol/mg of protein of endozepine or less.

Steroids	Minimal concentration required for induction
Cortisol	5 nm
Pregnenolone-sulfate	10 nm
Pregnenolone	50 nm
Progesterone	1000 nm
17α-Progesterone	No effect up to 10 μm
11α-Progesterone	No effect up to 10 μm
Aldosterone	No effect up to 10 μm
11-Deoxycortisol	Weak induction at 1 μm
Dexamethasone	Weak induction at 1 μm
