Objective: Diabetes mellitus is a metabolic disease of global importance. It affects many people by reducing their quality of life and even causing death. Therefore, research on diabetes mellitus maintains its popularity and continues to develop. Chard (Beta vulgaris L. var. cicla) is commonly used in diets and is known to have alternative hypoglycemic effects in diabetic individuals. This study investigated the protective effects of chard on glycoproteins (hexose, hexosamine, fucose and sialic acid) and the advanced oxidation protein product levels in diabetic rats’ livers. Materials and Methods: For this experiment, male Sprague–Daw-ley rats were separated into three groups: the control; Streptozotocin (STZ)-induced diabetic rats; and STZ-induced diabetic + chard extract. Fourteen days after diabetes induction, chard extract (2 g/kg/day, gavage) was administered for 45 days. On day 60, liver samples were collected, and 10% (w/v) homogenate was prepared for the analysis of glycoprotein components and advanced oxidation protein products. Results: Levels of glycoprotein parameters that include hexose, hexosamine, fucose, and sialic acid, as well as advanced oxidation protein product levels, increased in the diabetic group. Chard extract administration curatively reverted the altered biochemical parameters. Conclusion: From the results obtained, it can be suggested that chard extract has a protective effect on the diabetic livers of rats. © 2021, Istanbul University Press. All rights reserved.

The Protective Effects of Myrtus Communis Subsp. on Ovariectomized Diabetic Rats’ Renal and Intestinal Tissues: in Vivo and in Silico Approaches
(Taylor and Francis Ltd., 2025) Ertik, O.; Şener, Göksel; Kadıoğlu-Yaman, Beril; Şen, Ali; Şener, Göksel; Yanardag, Refiye; Eczacılık Meslek Bilimleri Bölümü
Introduction: Postmenopausal diabetes is a condition that affects millions of women and their quality of life. Also, kidney and small intestine tissues are damaged due to diabetes. The present study aimed to examine the protective effects of an extract prepared from Myrtus communis leaves on kidney and small intestine tissues against experimentally created postmenopausal diabetes. Methods: For this purpose, experimental rats were randomly divided into six groups (Control; ovariectomy:OVX, diabetic:D, ovariectomy + diabetic:OVX + D, ovariectomy + diabetic + oestrogen:OVX + D+E2, ovariectomy + diabetic + MC: OVX + D+MC) and kidney and small intestine tissues were taken after the experimental procedure. Results: Evaluations of biochemical parameters (glutathione and glutathione-related enzymes, antioxidant enzymes, etc.) showed that MC had a protective effect on kidney and small intestine tissues in diabetes and ovariectomy groups. Conclusion: It can be suggested that MC extract has a protective effect on small intestine and kidney tissues in postmenopausal diabetes and may be a good herbal source for this purpose. © 2024 Informa UK Limited, trading as Taylor & Francis Group.
