Several studies have reported on the appearance of cutaneous porphyria in @entity1 treated with @entity172 . This study was undertaken to investigate the effects of oral contraceptives (OCs) on levels of @entity7889 in urine in nonporphyric @entity1 . 30 @entity1 aged 21-40 and on OCs were observed as the study group, and 10 @entity1 using other contraceptive methods were observed as the control group. Urinary @entity7889 were measured by the Remington method. Levels of urinary @entity10474 and of urinary @entity10475 were higher in the study group than in the control group. These differences, however, are not statistically significant. To study the effect of duration of OC treatment, @entity1 who had taken OCs for 3-6 months and @entity1 who had taken OCs for longer than 6 months were observed, and the means of urinary @entity10474 and @entity10475 measured. Again, the differences were found to be insignificant, although slightly higher values of urinary @entity10474 were obtained for @entity1 who had been on OCs for a longer period. These results compare favorably with others reported in the published literature. It can be concluded that OC treatment has no significant bearing on @entity7170 metabolism.
