Article Effectiveness of Boric Acid in Sepsis in Rats With Cecal Perforation(Springer Nature, 2025) Kurtipek, Ali Can; Dursun, Ali Dogan; Yigman, Zeynep; Ozdemir, Cagri; Kucuk, Aysegul; Gonullu, Ugur; Arslan, MustafaIntroduction and AimSepsis is a systemic inflammatory response that develops in the host against microorganisms, which results in end-organ damage. Boric acid (BA) has been shown to have immune modulatory effects in vitro and in animal studies. The aim of the study is to investigate the effects of high dose BA on lung and kidney tissues in rats with sepsis induced by the CLP method.Method28 rats were randomly divided into four groups: Group C (control group), Group BA, Group CLP (cecal ligation and puncture), and Group CLP + BA. Cecum was ligated below the ileocecal valve and punctured. BA was administered to the treatment groups at an intraperitoneal dose of 200 mg/kg, and at the end of 24 h, lung and kidney tissue samples were collected and evaluated for biochemical and histopathological parameters.ResultsHistopathologically, in kidney tissue, CLP + BA group showed significantly less peritubular capillary dilatation and brush border loss in the proximal tubule epithelium compared to the CLP group. In lung tissue, CLP + BA group had significantly less alveolar wall thickening compared to the CLP group. Biochemical analyses indicated that BA administration reduced oxidative stress in both renal and lung tissues.ConclusionWe found that intraperitoneal administration of high dose boric acid partially ameliorated the tissue damage in rats subjected to CLP induced sepsis. Further studies are needed regarding the dosage and application at different time points.Article The Effect of Cerium Oxide on Liver and Kidney in Lower Extremity Ischemia Reperfusion Injury in Streptozotocin -Induced Diabetic Mice(Springernature, 2025) Erel, Selin; Ozdemir, Miray Gozde; Kucuk, Aysegul; Sarikaya, Badegul; Sezen, Saban Cem; Atli, Muharrem; Arslan, MustafaIntroductionIschemia-reperfusion injury (IRI) is a major concern in diabetic patients undergoing vascular procedures, causing significant damage to the liver and kidneys. The purpose of this study was to evaluate the protective effects of cerium oxide on the liver and kidneys of diabetic mice with lower extremity IRI.Materials and MethodsThirty Swiss albino mice were divided into five experimental groups: control (C), control diabetes (D), diabetes with cerium oxide (D-CEO2), diabetes with IRI (D-IRI), and diabetes with IRI treated with cerium oxide (D-IRI-CEO2). Diabetes was induced with streptozotocin (125 mg/kg) and lower-extremity IRI was induced by clamping the infrarenal aorta. Cerium oxide was administered intraperitoneally to the 0.5 mg/kg cerium oxide groups 30 min before ischemia. Liver and kidney tissue samples were subsequently analyzed through biochemical assays measuring the total antioxidant status, total oxidant status, oxidative stress index, and paraoxonase-1, as well as histopathological examinations.ResultsThe D-IRI group exhibited greater liver and kidney damage than the control group. The D-IRI-CeO2 group displayed reduced liver and kidney damage compared to the D-IRI group. In both the D-IRI and D-IRI-CeO2 groups, the total oxidant status, oxidative stress index, and paraoxonase-1 acitivity were higher, whereas the total antioxidant status levels were lower. In the D-IRI-CeO2 group, there was a decrease in total oxidant status, oxidative stress index, and paraoxonase-1, whereas total antioxidant status increased compared to D-IRI.ConclusionIntraperitoneal cerium oxide reduces oxidative stress and mitigates liver and kidney damage in diabetic mice subjected to lower extremity ischemia-reperfusion injury.
