Portulaca oleracea prevented hyperglycemia by preventing the oxidative stress and inflammation. - GreenMedInfo Summary

The present study was designed to investigate the protective effect of the aqueous extract of Portulaca oleracea against hyperglycemic, oxidative damage and inflammation in the serum of streptozotocin (STZ)-induced diabetic rats. In the present study, the rats were divided into the following groups of 8 animals each: control, untreated diabetic, 3 Portulaca oleracea (100, 200, 400 mg/kg/d)-treated diabetic groups. At the end of the 4-week period, glucose, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), malondialdehyde (MDA), glutathione (GSH), and total antioxidant status (TAS) levels were measured. STZ caused an elevation in the serum levels of glucose, MDA, IL-6, and TNF-α with reduction in the levels of GSH and TAS ( P<.01). Portulaca oleracea ameliorated glucose, MDA, IL-6, TNF-α, GSH, and TAS levels in diabetic groups versus to the untreated groups ( P<.05). Taken together, Portulaca oleracea prevented hyperglycemia by preventing the oxidative stress and inflammation.
