    Abstract:
    In this original article, we aimed to assess the ameliorative role of Cyanus depressus (CD) plant ethanolic extract treatment of streptozotocin (STZ)-induced liver, kidney, and pancreas damage in rats. The rats were divided into five groups (n = 7): control, CD, Diabetes mellitus (DM), DM + CD, and DM + glibenclamide (Gly). The DM groups were injected with a single dose of 50 mg/kg STZ intraperitoneally (i.p.). While the CD and DM + CD groups received 400 mg/kg/day intragastrically for 21 days, the DM + Gly group received 3 mg/kg/day of Gly intragastrically throughout the experiment. Statistically significance was accepted as p < .05. According to our liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) data, quinic acid, cosmosiin, nicotiflorin, apigenin, and protocatechuic acid were the major compounds, in descending order. Weekly blood glucose, serum glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) and urea, malondialdehyde (MDA) (liver and pancreas), and blood glycosylated hemoglobin % (HbA1c %) were significantly decreased, whereas finally live body weights (LBWs), reduced glutathione (GSH), glutathione S-transferase (GST) and catalase (CAT) (pancreas), and pancreatic islet diameter and area were increased significantly in the CD-treated diabetic group. Moreover, CD administration was found to be effective in the protection of the histology of the liver, kidneys, and pancreatic islets in the STZ-induced rats. Consequently, we concluded that CD administration reduces hyperglycemia, oxidative stress, and histopathology in STZ-induced experimental rats by improving antioxidant defenses. PRACTICAL APPLICATIONS: Today, the prevalence of diabetes is increasing rapidly throughout the world and it causes complications such as kidney damage, blindness, amputations, and cardiovascular diseases. Despite medical technological advances, people's interest in medicinal herbal products is gradually increasing. Biochemical and histopathological findings showed that the use of the plant CD at the determined dose (400 mg/kg/day) in rats with DM by STZ had strong antioxidant and antidiabetic effects. CD may have a drug potential in preventing DM and its complications because of its phytochemical content including some phenolic acids such as quinic acid, cosmosiin, nicotiflorin, apigenin, and protocatechuic acid. Isolation of bioactive compounds from CD and investigation of their therapeutic effects could be planned as further studies.
