Abstract
The aim of the present study was to determine whether serotonergic drugs could reverse lipopolysaccharide (LPS)-induced anorexia in rats. LPS ($500{\mu}g$/kg body weight) and all serotonergic drugs, except for 8-OH-DPAT (subcutaneous), were injected intraperitoneally into Sprague-Dawley rats. Without the LPS injection, 8-OH-DPAT (1A agonist), metergoline (1/2 antagonist), and mianserin (2A/2C antagonist) exerted no effects on food intake at any of the doses tested, but ketanserin (2A antagonist) caused an increase of food intake at 4 mg/kg. RS-102221 (2C antagonist) reduced food intake at 2 and 4 mg/kg. LPS reduced food intake 1 hour after injection, and food intake remained low until the end of measurement period (24 hours) (p<0.05). Pretreatment of rats with 8-OH-DPAT partially recovered of cumulative food intake at all measured times (2, 4, 6, 8, and 24 hours after LPS injection). Pretreatment with metergoline resulted in a partial recovery of cumulative food intake at 2, 4, 6, and 8 hours, but not at 24 hours. Ketanserin caused partial recovery at 2 and 4 hours only. Mianserin and RS-102221 had no effects on LPS-reduced food intake. A variety of serotonergic drugs ameliorated anorexic symptoms, which suggesting that the serotonin system plays a role in LPS-induced anorexia.
