The effects of topically applied steroids and of a dodecahydrophenanthrene were investigated by means of the sebaceous gland response. Compared with testosterone (= 1) the effects of 5α-dihydrotestosterone and 5β-dihydrotestosterone were found to be 0.6 and 0.26, respectively. Epitestosterone was ineffective in females, whereas in some males an increase in sebum production was observed. The. In today's examine, many of us systematically established the particular substrate specificity associated with homogeneous individual recombinant AKR1D1 making use of C18, C19, C21. and also C27 Delta(Some)-ketosteroids and also assessed the actual pH-rate dependence in the chemical.

Detected treatment effects on the C18 steroids were similar for the transformed and nontrans-formed data although P values did vary slightly. Results are presented as means (of the initial data) ± standard deviation, as a percentage of summed total steroids and as a percentage of each class (C21, C19 and C18). The prostate contained 20 different identified C18, C19, and C21 steroids (Table 1). Estradiol or DHEA-sulfate was the most abundant steroid in the prostate. Regardless of treatment, total C21,C19,C18 steroid concentrations in the prostate were ~50% C18, ~50% C19, and less than 10% C21 (Table 1). Total C18 steroids in letrozole-treated animals.
