Synthesis of 20 alpha-hydroxylated steroids by ovaries of the dab (Limanda limanda).

Gen. Comp. Endocrinol. 76(1) , 147-58, (1989)

Dab (Limanda limanda) ovarian fragments were incubated in vitro with either [4,7-3H]pregnenolone or 17 alpha-hydroxy[1,2,6,7-3H]progesterone to investigate the pattern of steroidogenesis. A major enzy...

Levels of 17 alpha,20 alpha-dihydroxy-4-pregnen-3-one, 3 beta,17 alpha,20 alpha-trihydroxy-5 beta-pregnane, and other sex steroids, in blood plasma of male dab, Limanda limanda (marine flatfish) injected with human chorionic gonadotrophin.

Gen. Comp. Endocrinol. 83(2) , 258-64, (1991)

In a previous study, plasma sex steroid levels were measured in female dab (Limanda limanda) induced to ovulate by injections of human chorionic gonadotrophin (HCG). In the present study, a similar ex...
