Cisplatin 151-160 ghrelin and obestatin prepropeptide Rattus norvegicus 31-35 18455814-8 2008 Cisplatin increased GHSR mRNA expression in the stomach (67%) and hypothalamus (52%) but not GHRL mRNA expression and increased the percentage of acylated GHRL (7.03+/-1.35% vs. 11.38+/-2.40%) in the plasma. Cisplatin 0-9 ghrelin and obestatin prepropeptide Rattus norvegicus 155-159 18455814-9 2008 Dexamethasone reduced the plasma level of acylated GHRL and the percentage of acylated GHRL to values below those in animals treated with saline alone (7.03+/-1.35% vs. 2.60+/-0.49%). Dexamethasone 0-13 ghrelin and obestatin prepropeptide Rattus norvegicus 51-55 18455814-9 2008 Dexamethasone reduced the plasma level of acylated GHRL and the percentage of acylated GHRL to values below those in animals treated with saline alone (7.03+/-1.35% vs. 2.60+/-0.49%).

Glucose 54-61 ghrelin and obestatin prepropeptide Rattus norvegicus 15-22 18385464-7 2008 In contrast, plasma ghrelin levels remained within the fasted levels in STZ rats after feeding. Streptozocin 72-75 ghrelin and obestatin prepropeptide Rattus norvegicus 20-27 18385464-9 2008 Treatments with anti-ghrelin antibodies attenuated accelerated gastric emptying in STZ rats (50.1 +/- 3.5%, n = 6, P < 0.05), while having little effect in vehicle control rats. Streptozocin 83-86 ghrelin and obestatin prepropeptide Rattus norvegicus 21-28 18385464-11 2008 Treatments with anti-ghrelin antibodies suppressed this enhanced antropyloric coordination in STZ rats. Streptozocin 94-97 ghrelin and obestatin prepropeptide Rattus norvegicus 21-28 18439428-12 2008 Components of rikkunshito, 3,3",4",5,6,7,8-heptamethoxyflavone, hesperidin, and iso-liquiritigenin showed a 5-HT2B-antagonistic effect in vitro, and oral administration of rikkunshito suppressed the cisplatin-induced decrease in the plasma acylated-ghrelin level.

Norepinephrine 119-133 ghrelin and obestatin prepropeptide Rattus norvegicus 38-45 18519241-9 2008 The attenuation of ghrelin-immunoreactivity of gastric mucosa, after a single injection of R-(+)-methanandamide and CP 55,940 was accompanied by a significant increase of ghrelin plasma concentration. methanandamide 91-111 ghrelin and obestatin prepropeptide Rattus norvegicus 19-26 18253047-11 2008 Serum concentrations of ghrelin, obestatin, leptin, gastrin, and pancreastatin were greatly reduced after Gx. glycinexylidide 106-108 ghrelin and obestatin prepropeptide Rattus norvegicus 24-31 18519241-9 2008 The attenuation of ghrelin-immunoreactivity of gastric mucosa, after a single injection of R-(+)-methanandamide and CP 55,940 was accompanied by a significant increase of ghrelin plasma concentration. methanandamide 91-111 ghrelin and obestatin prepropeptide Rattus norvegicus 171-178 19141406-10 2008 Those observations may indicate, that chronic administration of L-thyroxine cause the change of ghrelin plasma concentration in rats, probably via direct influence on gastric X/A-like cells, but this effect is not responsible for hyperphagia associated with hyperthyroidism. Thyroxine 64-75 ghrelin and obestatin prepropeptide Rattus norvegicus 96-103 18519241-10 2008 These results indicate that stimulation of appetite exerted by cannabinoids may be connected with an increase of ghrelin secretion from gastric X/A-like cells.
