Abstract
The purpose of this study is to evaluate the preventive effects of Urtica dioica (UD) on muscle ischemia/reperfusion (I/R) injury. A total of 27 male Wistar rats were divided into three groups as the control group (1), I/R + saline group (2), and I/R+UD group (3). Group 1 did not receive any treatment. Group 2 was administered a total of 2mL/kg saline (1mL/kg before ischemia and 1 mL/kg after reperfusion), and group 3 was given a total of 2mL of UD (1mL/kg before ischemia and 1mL/kg after reperfusion) as treatment. Saline and UD were administered via intraesophageal canula once a day for five days. At the end of five days, all the rats were exposed to muscle ischemia for 60 min followed by 60 min of reperfusion of the bilateral hindlimbs induced using a tourniquet. Muscle tissue histopathologies were evaluated by light microscopy. Furthermore, oxidative/nitrosative stress biomarkers such as catalase (CAT), superoxide dismutase (SOD), malondialdehyde (MDA), nitrotyrosine (3-NT), nitric oxide (NO), and myeloperoxidase (MPO) as an inflammatory marker in tissue samples were measured. UD treatment significantly decreased oxidative/nitrosative stress biomarker levels and MPO (p<0.05). We established that UD treatment could alleviate muscle injury induced by muscle I/R in rats by inhibiting the inflammation and oxidative/nitrosative stress.
