Our study illustrated that restocking in a wild habitat might have significantly decreased the blood potassium content within 30 d compared with that in the Ori group ( p < 0.05), but it might have been gradually restored to the normal level with an increasing trend ( Table S1 ).
The combustion oxidation products of PBBs showed an increasing trend in toxicity; for instance, products after combustion of PBB-4 and PBB-29 increased from toxic to highly toxic, indicating a significant biological toxicity that warrants attention, consistent with the high mutagenic and carcinogenic risks associated with the combustion oxidation products of PBBs.
(4) Decreased 17-hydroxy-pregnane levels after treatment with anti-MS drugs in FP indicate a decreasing trend of CYP17A1 activity, suggesting a weakening of one of the steps of the cortisol pathway and, together with the analysis for individual anti-MS drugs, a strengthening of the step toward immunomodulatory adrenal androgens.
Concerning our current data, although the levels of 7α/β- and 16α-hydroxy-steroids did not show a significant trend toward changes after treatment with anti-MS drugs, the SMRs of 7α/β- and 16α-hydroxy-steroids to the parent steroids suggested a reduction in the activities of the enzymes catalyzing their synthesis (CYP7B1, CYP3A4, and CYP3A7) of borderline significance despite the low number of corresponding SMRs ( n = 8).
The results from our previous study suggested an overall trend toward impaired adrenal activity in patients, which may affect the synthesis of most steroids (including active steroid hormones and neuroactive, neuroprotective, and immunoprotective steroids) found downstream in the metabolic pathway [ 33 ].
