Abstract:
Administration of 6 mM silver nitrate in the drinking water of mice resulted in deposition within the glomerular basement membrane of silver granules which were detected on electron microscopy after 12 days. Larger aggregates were detected in the basement membrane and mesangium when silver ingestion was extended to 14 weeks. The silver deposits did not alter significantly over a period of 21 weeks after silver nitrate ingestion was stopped.
Insights
Mice drinking silver nitrate developed silver granules in kidney glomeruli within 12 days. These deposits persisted long after silver exposure ceased, indicating potential long-term effects of silver accumulation.
Area of Science:
- Nephrology
- Toxicology
- Materials Science
Background:
- Silver compounds are used in various applications.
- Understanding the biological fate and deposition of silver is crucial.
Purpose of the Study:
- To investigate the deposition and persistence of silver in mouse kidneys following oral administration of silver nitrate.
Main Methods:
- Mice were administered 6 mM silver nitrate in drinking water.
- Kidney tissues were examined using electron microscopy at various time points.
- Silver deposition was assessed in the glomerular basement membrane, mesangium, and other renal structures.
Main Results:
- Silver granules were detected in the glomerular basement membrane after 12 days of silver nitrate administration.
- Larger silver aggregates formed in the basement membrane and mesangium with extended ingestion (14 weeks).
- Deposited silver remained significantly unchanged for 21 weeks after cessation of silver nitrate intake.
Conclusions:
- Oral silver nitrate administration leads to significant silver deposition in mouse renal glomeruli.
- These silver deposits exhibit long-term persistence in kidney tissues.
- The findings highlight the potential for bioaccumulation of silver in renal structures.
