[Genotoxic damage induced by indium chloride on rat]

Area of Science:

• Toxicology
• Genotoxicity testing
• Environmental health

Background:

• Indium compounds are increasingly used in industry.
• Understanding the toxicological profile of indium chloride is crucial for occupational safety and risk assessment.

Purpose of the Study:

• To evaluate the genotoxic effects of indium chloride in vivo.
• To assess the impact of indium chloride exposure on oxidative stress and lung pathology.
• To establish a scientific basis for indium compound toxicity evaluation.

Main Methods:

• In vivo bone marrow micronucleus test in Wistar rats.
• Endotracheal injection of indium chloride at varying doses.
• Histopathological analysis using Hematoxylin and eosin (H&E) staining.
• Measurement of oxidative stress markers (SOD, MDA) and indium content (ICP-MS).

Main Results:

• Significant increase in indium levels in blood and lung tissue.
• Elevated micronucleus rate in bone marrow cells.
• Increased MDA and decreased SOD levels in lung tissue, indicating oxidative stress.
• Pathological lung changes including inflammation and proteinaceous material in alveolar spaces.

Conclusions:

• Indium chloride exposure leads to indium accumulation in blood and lungs.
• It induces genotoxicity, evidenced by increased micronucleus rates.
• Exposure causes oxidative damage and significant lung pathology.
