Tetramine dichloro-palladium subcellular localization in the kidney: electron microprobe study
Journal of Submicroscopic Cytology
|January 1, 1987
Summary
Tetramine dichloro-palladium accumulation in kidney cell lysosomes was observed, potentially linked to sulfatase activity. Iron concentration may inhibit red blood cell production, impacting therapeutic applications.
Area of Science:
- Nephrology
- Toxicology
- Biochemistry
Background:
- Palladium salts are explored in experimental therapy.
- Understanding their kidney cell interactions is crucial.
Purpose of the Study:
- Investigate tetramine dichloro-palladium effects on kidney cells.
- Compare palladium's cellular uptake with Cis-diaminedichloro-platinum (Cis-DDP).
Main Methods:
- Electron microprobe analysis of kidney proximal tubule cells.
- Comparison with Cis-diaminedichloro-platinum (Cis-DDP) data.
Main Results:
- Palladium detected in lysosomes, associated with sulfur and iron.
- Intralysosomal palladium concentration linked to sulfatase activity.
- Iron concentration correlated with erythropoiesis inhibition.
Conclusions:
- Tetramine dichloro-palladium concentrates within kidney lysosomes.
- Sulfatase activity may mediate palladium accumulation.
- Observed iron effects warrant further investigation for therapeutic safety.
