It was presented that DEX had radioprotective effect on the liver after I-131 therapy and anti-inflammatory and antioxidant activities are likely to be involved in the mechanism underlying the radioprotective effects of DEX. After further studies, DEX might be used as a hepatoprotective treatment regimen before administering radioactive iodine therapy particularly in patients with hepatic disease.

The results of this study demonstrated that melatonin reduced the harmful effects of RAI treatment on the liver. Anti-inflammatory and antioxidant activities are likely to be involved in the mechanism underlying the radio-protective effects of melatonin (Tab. 3, Fig. 1, Ref. 30).

The rectally administered argan oil was observed to have significantly ameliorated wound healing parameters and exerted a significant antioxidant effect. This is the first study in the literature about the beneficial effects of argan oil on colorectal anastomoses.

Background Distal pancreatectomy (DP) is the main surgical treatment of benign and malignant lesions located in pancreatic body and tail. Postoperative pancreatic fistula (POPF) following DP is still a considerable cause of morbidity. Identification of risk factors for POPF after DP might provide some preventive applications. We aimed to evaluate the factors affecting POPF after DP and to present a new and easy radiological predictive factor. Materials and Methods Thirty-four patients underwent DP with stapler closure were included. Several risk factors for clinically relevant POPF (CR-POPF) were analyzed. Additionally, computed tomography findings of pancreatic thickness (PT), main pancreatic duct diameter (MPDD), and PT/MPDD ratio were evaluated for POPF. Results CR-POPF was observed in 10 patients (29.4%). Univariate and multivariate analyses showed that previous abdominal surgery and PT/MPDD ratio were predictive factors for CR-POPF after DP ( P = 0.040, P = 0.034, respectively). The cutoff value for the PT/MPDD ratio was 8. Conclusion A PT/MPDD ratio greater than 8 (a wide pancreas with a narrow duct) is a significant predictive factor for CR-POPF following DP.
