Continuation of [[SNA Lithium Orotate CTA]] and [[SNB Lithium Orotate CTA 2]] and [[SNC Non-Contingent Lithium Orotate]] [[SND Lithium Orotate Inhibitors]]
Test if OAT inhibitor naringin and UMPS inhibitor 6-azauracil decrease effectiveness of lithium orotate (LiOr) in inducing a conditioned taste aversion.
Inject narinign and 6-azauracil 30 min before single pairing of saccharin intake (15 min) after 15-min delay with LiOr.
From Pacholko 2023 PMID 37356352:
naringin MW 580.53 [https://www.sigmaaldrich.com/US/en/product/sigma/71162 Sigma 71162-35g] $50.78: organic anion transporting polypeptide 1A2 (OATP1A2) inhibitor
6-azauracil MW 113.07 [https://www.sigmaaldrich.com/US/en/product/sigma/a1757 Sigma A1757-5g] $99.90: UMPS inhibitor
For injection, combine 100 mg/kg naringin (17mM) + 30 mg/kg 6-azauracil (27mM) dissolved in saline/10% DMSO; in 10 ml/kg i.p. injection.
* measure 400mg naringin + 120mg 6-azuracil;
* dissolve in 4ml DMSO with heavy vortexing
* slowly add 36 ml sterile injectable 0.9% saline, with frequent vortexing (-> clear light yellow solution)
* filter
Use 10% DMSO in injectable 0.9% saline as vehicle control.

===Agenda===
Rats arrive (XXXX), n=16 adult male Sprague Dawley rats (Charles River CD, d.o.b XXX), individually housed in BRF 169.
<br>
'''Day 0: Water removed''' (2026-7-7)
make labels for bottles.
<br>
'''Days 1 - 6: Water Restriction''' (2026-7-8 thru 2026-6-13)
Weigh rats daily. ad lib food.
30 min, 30 min, 30 min, 30 min, 30 min, 15 min water at 1000 daily.
1 water bottle, 1 empty bottle to accustom to 2-bottle choice
<br>
'''Day 7: Conditioning Day''' (2026-7-14)
-30 min (~930): rats injected with naringin (100mg/kg) + 6-azauracil (30mg/kg) or saline vehicle, 10 ml/kg ip
0 min (~1000): all rats 15 min access to 0.125% saccharin (5 g sodium saccharin/4L water)
30 min (~1030): 6 rats injected with 75 mM LiOr, 6 ml/kg ip, or Tris-NaCl vehicle.
Thus, four groups:
* Veh-Veh (SNE01,05,09,13)
* NA-Veh (SNE02,06,10,14)
* Veh-LiOr (SNE03,07,11,15)
* NA-LiOr (SNE04,08,12,16)
Ad lib water returned after final injection overnight.
'''Days 8 - 22: Preference Tests''' (2026-7-15 through 2026-7-30)
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 14 days.
