  2. Introduction • Scientists use animals when the use of humans iseither impractical or unethical. • For example when scientists investigate fetal alcohol syndrome, they cannot give alcohol to pregnant women but they can give to pregnant animals such as rats. • Scientific research with animals has contributed to many important advances in scientific & medical knowledge.

  3. Intro Cont • .Mice and rats are a useful model for studying the effects of alcohol. • The SD rats are more active during the night then during the day. • SD rat is a general model for the study of human health and disease. • The SD rats is a widely accepted, dependable, general purpose research model used in virtually all disciplines of biomedical research including toxicology and pharmacology.

  5. Materials • Sprague Dawley (SD) rats • 1% concentration=10ml EtOH, 990ml H2O • 3% concentration=30ml EtOH, 970ml H2O • 5% concentration=50ml EtOH, 950ml H2O • 7% concentration= 70ml EtOH, 920ml H2O • 9% concentration=100ml EtOH,910ml H2O

  7. Methods • We feed EtOH to SD rats once a week. We weight the bottles into grams (g) before we feed them and also after we feed them. • Record the time we place the bottles on the cage. • Wait exactly one hour before we remove the bottles. • Each rat has its own separate EtOH and H2O bottle. • There is 22 SD rats, Each bottle is numbered 1-22 for rat 1-22 there was sign that was set up for the bottle. • Bottles with orange tape are for EtOh and those with blue are for water (rats#1 gets orange#1 and blue #1)

  8. Que$tion • Do SD rats drink more alcohol (EtOH) than water (H20), or more water (H20) than alcohol (EtOH)?
