Oxidative stress is the trigger of several diseases. It is an imbalance between the production of free radicals and antioxidants. is studyaimstoevaluatetheantioxidantcapacityandtheprotectivepropertyof Rosacanina fruitsandapplecidervinegarcombined or not against hydrogen peroxide (H 2 O 2 )-induced toxicity in Wistar rats. e experiment included five groups: group 1 received distilled water (10mL/kg b.wt), group 2 received H 2 O 2 10% (10mL/kg b.wt), group 3 received H 2 O 2 10% (10mL/kg b.wt) and applevinegar(2mL/kgb.wt);group4receivedH 2 O 2 10%(10mL/kgb.wt)andapplevinegarsupplementedwith Rosacanina fruits extract (300mg/kg b.wt); group 5 received H 2 O 2 10% (10mL/kg b.wt) and extract of Rosa canina fruits (300mg/kg b.wt). e dosesweregivenoncedailyviaagavage.eantioxidantcapacityofapplevinegarand Rosacanina extractwasanalyzed,andAST, ALT, PAL, urea, and creatinine were determined on day 22 of the experiment. In addition, the kidney and the liver tissues were analyzed. e results showed that H 2 O 2 caused a significant elevation of blood urea, blood creatinine, and transaminases. e histopathology examination revealed that H 2 O 2 caused congestion, hemorrhage, and Bowman’s space enlarged.

In conclusion, the two natural products studied in this work are effective against the harmful effect of oxidative stress, which explains their use in traditional medicine. 1.Introduction Oxidative stress induces an increase in the production of free radicals considered as drivers of different pathogenesis and organ damages. It could disturb the antioxidant system and lead to direct cellular injury stress in the liver and kidney [1]. Numerous factors can induce this imbalance such as acidosis, nitric oxide, transition metals, LDL oxidation [2], and toxic agentsincludinghydrogenperoxide(H 2 O 2 )[3].Furthermore, H 2 O 2 can permeate across the membrane as a destructive agent and generate hydroxyl radicals [3]. Other producers of reactive oxygen species (ROS) can induce necrosis and ap- optosis [4]. Numerous reports have well established that oxidative stress is the major cause of various pathologies. Nowadays, the use of natural products turns out to be a goodalternativetochemicals,thesideeffectsofwhichcanbe serious [5, 6]. Fruits and their byproducts have tremendous beneficial properties. Among a long list of fruits wealthy on bioactive compounds with enormous utilizations in folk medicine, we found Rosa canina fruits. Several studies evoked that Rosa Canina fruits were used in alternative medicine to treat different diseases including diabetes mellitus, colds, fever, scurvy, and kidney diseases [7]. e wealth of hips on phytochemicals with high antioxidant ability improves cell longevity and obstructs skin aging as previously proved by Phetcharat et al [8].
