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

Groups:

  • Sham + NaCl: DMP08, DMP17
  • Sham + Butyrate: DMP07, DMP09, DMP16

ad lib water returned after final injection overnight.


Days 9 - 23: Preference Tests: 2021-11-17 to 2021-11-27

Rats CTA acquisition and extinction was measured with 24-h, 2-bottle preference tests (for 14 days). Rats were given 24-h free access to both 0.125% saccharin and water bottles, alternating position for 10 days.
