چکیده مقاله :

مقاومت انسولینی کبدی به شدت با NAFLD ارتباط داشته و فاکتور اصلی در بیماریزایی دیابت نوع 2 و سندرم متابولیک است. مقاومت به انسولین سبب لیپولیز در بافت چربی شده و اختلال در تنظیم متابولیسم لیپیدی سبب انباشته شدن چربی در کبد می‌شود. در این مطالعه اثرات بربرین و سیتاگلیپتین برای بهبود مقاومت به انسولین و پروفایل لیپیدی در موش‌های اسپراگ-داولی مبتلا به دیابت نوع 2 بررسی شده است. گروه‌ها شامل: 1- کنترل (سرم فیزیولوژی به عنوان حلال آلوکسان)؛ 2- مدل (کبد چرب + آلوکسان)؛ 3- سیتاگلیپتین (کبد چرب + آلوکسان و 10 میلی گرم/کیلوگرم سیتاگلیپتین)؛ 4- بربرین (کبدچرب + آلوکسان و 150 میلی گرم/کیلوگرم بربرین)؛ 5- بربرین/سیتاگلیپتین (کبد چرب + آلوکسان و 5 میلی گرم/کیلوگرم سیتاگلیپتین و 75 میلی گرم/کیلوگرم بربرین). پس از اتمام دوره تیمار در شرایط بیهوشی خونگیری از قلب انجام گرفت و میزان پروفایل لیپیدی، گلوکز، انسولین سنجش شد. میزان تری‌گلیسرید (01/0 p <)، کلسترول (05/0 p <)، LDL(01/0 p <)، اسید چرب آزاد (05/0 p <)، گلوکز ناشتا (05/0 p <) و انسولین (01/0 p <) در گروه تیمار توام نسبت به گروه مدل کاهش و HDL افزایش یافت که این افزایش معنی‌دار نبود. بربرین و سیتاگلیپتین بویژه در تجویز توام اثر مطلوبی در متابولیسم لیپیدها و مقاومت به انسولین دارند و می‌توانند به عنوان یک رژیم درمانی مؤثر برای هایپرلیپیدمی و کبد چرب در نظر گرفته شوند.

چکیده انگلیسی:

Hepatic insulin resistance is associated with NAFLD and it is a major factor in the pathogenesis of type 2 diabetes and metabolic syndrome. Insulin resistance causes lipolysis in adipose tissue and disturbance in the regulation of lipid metabolism causes fat accumulation in the liver. In this study, the biological activities of Berberine and Sitagliptin to improve insulin resistance and lipid profile in Sprague-Dawley rats with type 2 diabetes was investigated. groups include 1: control (physiological serum as an alloxan solvent); 2: model (fatty liver + Alloxan); 3: Sitagliptin (fatty liver + Alloxan and Sitagliptin 10 mg/kg); 4: Berberine (fatty liver + Alloxan and Berberine 150mg/kg); 5: Berberine/Sitagliptin (fatty liver + Alloxan and Sitagliptin 5 mg/kg and Berberine 75 mg/kg). At the end of the treatment period, under anesthesia, Blood sampling done from the heart and lipid profile, glucose and insulin measured. The amount of triglyceride (p < 0.01), cholesterol (p < 0.05), LDL (p < 0.01), FFA (p < 0.05), fasting glucose (p < 0.05) and insulin (p < 0.01) in the coadministration group decreased compared to the model group and HDL increased, which was not significant. Berberine and Sitagliptin, especially when administered together, have a favorable effect on lipid metabolism and insulin resistance and can be considered as an effective treatment regimen for hyperlipidemia and fatty liver.
