Description
Summary:It is known that diabetes mellitus has late complications, including microvascular and macrovascular diseases. Diabetes can affect bones through biochemical markers of bone structure, density, and turnover. This study aimed to biomechanically investigate the bone-protective effects of angiotensin 1-7 (Ang 1-7), one of the active peptides in the renin-angiotensin system, in rats with diabetes. Thirty male Wistar albino rats, three months old and weighing 250-300 g, were divided into four groups: diabetes, Ang 1-7, diabetes plus Ang 1-7, and control. One month later, diabetes developed in rats; the rats were sacrificed, and their right femur was removed. Three-point bending biomechanical tests were performed on the femurs. The diabetic group had significantly higher bone fragility than the other groups (Pr >.05). Bone fragility was lower, and bone flexibility was higher in the Ang 1-7 groups (Pr>F value 0.05). As a result of our study, the effect of Ang 1-7 on the bones of rats with diabetes was investigated biomechanically. Ang 1-7 has a protective impact on the bones of rats with diabetes. KEY WORDS: Diabetes mellitus; Angiotensin 1-7; Three point bending test; Bone; Renin-angiotensin system. Se sabe que la diabetes mellitus tiene complicaciones tardias, incluyendo enfermedades microvasculares y macrovasculares. La diabetes puede afectar los huesos a traves de los marcadores bioquimicos de la estructura, la densidad y el recambio oseo. Este estudio tuvo como objetivo investigar biomecanicamente los efectos protectores en los huesos de la angiotensina 1-7 (Ang 1-7), uno de los peptidos activos en el sistema renina-angiotensina, en ratas con diabetes. Treinta ratas albinas Wistar macho, de tres meses de edad y con un peso de 250-300 g, se dividieron en cuatro grupos: diabetes, Ang 1-7, diabetes mas Ang 1-7 y control. Un mes despues, se desarrollo diabetes en ratas; se sacrificaron los animales y se extrajo su femur derecho. Se realizaron pruebas biomecanicas de flexion de tres puntos en los femures. El grupo diabeticos tenia una fragilidad osea significativamente mayor que los otros grupos (Pr > 0,05). La fragilidad osea fue menor y la flexibilidad osea fue mayor en los grupos Ang 1-7 (valor Pr>F 0,05). Como resultado de nuestro estudio, se determino biomecanicamente el efecto de Ang 1-7 en los huesos de ratas con diabetes. Se concluye que Ang 1-7 tiene un impacto protector en los huesos de ratas diabeticas. PALABRAS CLAVE: Diabetes mellitus; Angiotensina 1-7; Prueba de flexion de tres puntos; Hueso; Sistema renina-angiotensina.
