Figure 4.

Comparative analysis of the effects of gelsemine and G. sempervirens at 9 or 5 cH on [³H]PROG conversion into [³H]3α,5α-THP by SC slices. The values were obtained from experiments similar to those presented in Figure 1. Results were then expressed as percentages of the amount of [³H]3α,5α-THP formed in the control group. Each value is the mean (±SEM) of four independent experiments. *P < .05, ***P < .001 as compared to control; ^# P < .05, ^## P < .01 as compared to gelsemine (ANOVA followed by Bonferroni's test).
