Crocetin (CRT), one of the active ingredients in saffron, exerts health-promoting effects on body systems such as neuroprotective, cardioprotective and hepatoprotective properties. In the present study, the effects of CRT and lansoprazole (LAP), as a reference drug, were investigated on indomethacin (IND)-induced gastric ulcer and related anxiety. Thirty rats were divided into five groups of six. Groups 1 and 2 received vehicle and groups 3, 4 and 5 received CRT (5 and 20 mg/kg) and LAP (30 mg/kg) for seven consecutive days. All groups were deprived of food on day 6. On day 7, group 1 was treated with vehicle and groups 2, 3, 4 and 5 received 50 mg/kg IND. Anxiety and locomotor activity were recorded, and then the animals were euthanized and stomach and hippocampus samples were taken. The effects of the aforementioned treatments were studied in 24 intact rats in four equal groups. CRT (20 mg/kg) and LAP restored IND-induced alterations in the gastric content volume and pH and ulcer index and protection and cyclooxygenases 1 and 2 and prostaglandin E2 and gastric mucosal and hippocampal superoxide dismutase, malondialdehyde, tumor necrosis factor-alpha, interleukin-1β and caspase-3 and hippocampal brain derived neurotrophic factor. Histopathological alterations in the gastric mucosa and hippocampus were improved, and anxiety was suppressed. Intact rats were not influenced. CRT and LAP caused protective effects against IND-induced gastric ulcer and by antioxidative, anti-inflammatory, anti-apoptotic and PGE Show less
