Alternatives to Animal Testing
- Emphasis on alternatives: reduction of animal suffering and promotion of humane treatment
Psychological Impacts
- Minimizing psychological impacts: careful consideration of animal welfare and stress minimization
Transparency and Accountability
- Importance of transparency and accountability: ensuring responsible and ethical conduct of tests
Chronic Toxicity Testing
- Monitored parameters: physiological, biochemical, and histopathological changes
- Common route of administration: oral, dermal, or inhalation
Hematological and Biochemical Parameters
- Purpose of monitoring: detection of adverse effects and organ damage
Ethical Principles
- Reducing the number of animals used: 3Rs principle, particularly Replacement
