Hypothesis
Mesna administration affects the concentrations of thiols in plasma.
Conclusion
Mesna depletes circulating cyst(e)ine and alters the sulfhydryl status of cells in vivo.
Supporting Evidence
- Intravenous mesna increased free cysteine levels significantly.
- Total cyst(e)ine levels decreased after mesna administration.
- Urinary excretion of cysteine increased following mesna treatment.
Takeaway
Mesna is a drug that can change the levels of certain important substances in the blood, which might help protect cells during cancer treatment.
Methodology
The study measured plasma concentrations of cysteine and glutathione after intravenous and oral administration of mesna to healthy volunteers.
Limitations
The study involved a small sample size and only healthy volunteers.
Participant Demographics
Eight healthy volunteers, two females and six males, aged 24 to 39 years.
