Epilobium hirsutum L., commonly known as hairy willowherb, is a perennial herbaceous plant native to Europe and Asia. In Romania, the Epilobium genus includes 17 species that are used in folk medicine for various purposes. This study aimed to investigate the anti-inflammatory and antitumor potential of the optimized extract of Epilobium hirsutum (EH) in animal models. The first study investigated the anti-inflammatory properties of EH optimized extract and the model used was carrageenan-induced paw inflammation. Wistar rats were divided into three groups: negative control, positive control treated with indomethacin, and a group treated with the extract. Oxidative stress markers, cytokine levels, and protein expressions were assessed. The extract demonstrated anti-inflammatory properties comparable to those of the control group. In the second study, the antitumor effects of the extract were assessed using the tumor model of Ehrlich ascites carcinoma. Swiss albino mice with Ehrlich ascites were divided into four groups: negative, positive treated with cyclophosphamide (Cph), Group 3 treated with Cph and EH optimized extract, and Group 4 treated with extract alone. Samples from the ascites fluid, liver, and heart were analyzed to evaluate oxidative stress, inflammation, and cancer markers. The extract showed a reduction in tumor-associated inflammation and oxidative stress. Overall, the EH optimized extract exhibited promising anti-inflammatory and antitumor effects in the animal models studied. These findings suggest its potential as a natural adjuvant therapeutic agent for addressing inflammation and oxidative stress induced by different pathologies. [ABSTRACT FROM AUTHOR]

The article titled "Evaluating Hepatic Toxicity of Chitosan and Chitosan-Functionalized Iron Oxide Nanoparticles in a Rat Model of Peripheral Nerve Injury -- Relevance for Rehabilitation Medicine" by Nadina Liana Pop et al. was published in the Balneo & PRM Research Journal in June 2024. The study examines the potential liver toxicity of chitosan and chitosan-functionalized iron oxide nanoparticles in a rat model of peripheral nerve injury. The authors aim to determine the relevance of these findings for rehabilitation medicine. The article provides the necessary references and contact information for further exploration.
