Abstract
The aim of this study was focused on investigating the possible protective effect of Nigella sativa L. seed extract against cisplatin-induced delay in gastric emptying, in a rat model. Twenty-five male Sprague-Dawley rats were divided into five equal groups as follows: Group I or control group, Group II (cisplatin 10 mg/kg, i.p at day 5), Group III (N. sativa L. 250 mg/kg for 5 days + cisplatin 10 mg/kg, i.p on day 5), Group IV (N. sativa L. 500 mg/kg for 5 days + cisplatin 10 mg/kg, i.p on day 5) and Group V (ondansetron 3 mg/kg/day, per os + cisplatin 10 mg/kg, i.p on day 5). Phenol red meal was adopted to estimate gastric emptying in different groups of the rats. Gastric emptying was significantly increased (p < 0.01) in N. sativa L. seed extract-pretreated rats (Group III and Group IV) when compared to cisplatin treatment alone (Group II). However, ondansetron produced significantly (p < 0.01) better reversal than N. sativa L. seed extract.
