We aimed to determine the protective effects of thymoquinone (TQ), against ischaemia-reperfusion (I/R) injury in the testis tissue of rats. Twenty-seven male Wistar albino rats were randomly divided into three equal groups as follows: Group I, sham group; Group II, torsion group; and Group III, torsion + thymoquinone group. The ischaemia period was 2 h, and orchiectomy was performed after 30 min of detorsion. Testis tissue sections were analysed with the terminal transferase mediated dUTP-nick end labelling (TUNEL) assay to determine in situ apoptotic DNA fragmentation. Additionally, Caspase 3 and Bax proteins were analysed immunohistochemically. The superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) activity levels in the testis tissue were also measured. The superoxide dismutase activity and malondialdehyde levels in the torsion group were significantly higher than those of the sham group (P < 0.05). Thymoquinone administration significantly reduced these levels. Torsion significantly increased active-Caspase 3 and Bax expression, which was decreased by thymoquinone. The apoptotic index of the torsion group was significantly higher than that of the control group. However, thymoquinone significantly reduced the apoptotic index (P < 0.05). Our results indicate that thymoquinone plays a protective role in oxidative stress induced ischaemia-reperfusion in the testis tissue of rats.

BACKGROUND: The management of food impaction and foreign body ingestion in the upper gastrointestinal tract requires careful evaluation and timely intervention. This study was a retrospective evaluation of the management of adult patients with such a history. METHODS: This study included adult patients admitted to a tertiary medical center with foreign body ingestion or food impaction between January 2012 and January 2018. The demographic and clinical data were recorded pro forma for statistical analysis. RESULTS: Of the 122 patients included in this study, 53.2% were male, and the mean age was 46.68±18.64 years. In 84 of the patients (68.8%), the ingested object was food. Thirty patients were managed solely through laryngoscopy, while 61 patients (50%) underwent a flexible endoscopy. The patients with a foreign body ingestion were older than those with a food impaction (mean age: 51.3±17.4 vs. 36.5±17.4 years; p<0.001) and a plain radiograph showed the ingested material more often in those patients (36.8% vs 10.7%; p<0.001). Two patients underwent surgery due to perforations caused by the impacted material. No mortality was observed. CONCLUSION: The management of a foreign body ingestion or food impaction in an emergency setting requires a stepwise, algorithmic approach.
