Agenda
Rats arrive (2021-08-24) Female Sprague Dawley rats n=18 (dob 2021-06-07), arrived
Surgery
3 groups: sham surgery, ovariectomized (ovx), ovariectomized + 3mg pellet of 17-beta-estradiol (Innovative Research, Sarasota, FL)
- DMP1-9: Surgery on 2021-10-24
- DMP10-18: Surgery on 2021-10-30
Carpofen 0.5 mg/kg pre-op, isoflurane and bupivicaine intra-op, carpofen 0.5 mg/kg post-op (next day). Staples removed 7 days post-op.
Day 0: Water removed 2021-11-08
Days 1-7: Water Restriction 2021-11-9 thru 2021-11-15
Weigh rats daily. Water for 10 min, ad lib food.
10 min water at 1400 daily.
Day 8: Conditioning Day 2021-11-16
- 0-30 min: saccharin 0.125%
- at 30 min: 3 ml/kg of 0.15M LiCl ip (all rats)
- at 40 min: 12 ml/kg of 0.3M NaButyrate or NaCl
ad lib water returned after final injection overnight.
Days 9- ???: Preference Tests: 2021-11-17 to ???
Rats CTA acquisition and extinction was measured with 24-h, 2-bottle preference tests. Rats were given 24-h free access to both 0.125% saccharin and water bottles, alternating position for 10 days.
