ABSTRACT

Introduction:

type 2 diabetes (T2DM) is a complex disease affected by lifestyle and genetic factors. Although the drugs currently used to treat T2DM have certain curative effects, they still have some adverse side effects. Therefore, it is urgent to find new effective drugs with few side effects to cure T2DM.

Objective:

to study the role of Inonotus obliquus (IO) in diabetic model mice.

Methods:

we used high-fat diet (HFD) combined with streptozocin (STZ) to establish a diabetic mouse model. Mice were divided into non-high-fat diet group (ND), diabetes model group (HFD + STZ) and IO-treated diabetes model group (IO). The mice in the IO group were orally treated with IO (150 mg/kg) at 10 ml/kg for five weeks. Body weight, glucose level, food intake and water consumption, glucose tolerance and insulin tolerance were evaluated in all mice. The pathological sections of liver, kidney and pancreas were observed by hematoxylin-eosin staining.

Results:

after IO administration, the blood glucose level, water consumption, low-density lipoprotein (LDL) and triacylglycerol (TG) levels of mice decreased. Compared with the HFD + STZ group, the number of normal islet iiiiiiii cells increased and focal necrosis of the liver was significantly reduced in the IO administration group.

Conclusions:

IO reduced the levels of blood glucose, restored body weight, and enhanced insulin sensitivity along with insulin tolerance and glucose tolerance in diabetic mice. Additionally, IO also reversed HFD and STZ-induced organ injury. (AU)
RESUMEN

Introducción:

la diabetes mellitus tipo 2 (T2DM) es una enfermedad compleja influenciada por el estilo de vida y los factores genéticos. En la actualidad, aunque los medicamentos para la diabetes tipo 2 tienen cierto efecto curativo, todavía tienen algunos efectos secundarios. Por lo tanto, es urgente encontrar nuevos medicamentos para la diabetes tipo 2 que tengan un buen efecto curativo y menos efectos secundarios.

Objetivo:

estudiar el papel del Inonotus obliquus (IO) en ratones diabéticos.

Métodos:

se estableció un modelo de ratón diabético con dieta de alto contenido en grasas (HFD) y estreptozocina (STZ). Los ratones se dividieron en el grupo de dieta no alta en grasas (ND), el grupo modelo de diabetes mellitus (HFD + STZ) y el grupo modelo de diabetes mellitus tratado con IO. Los ratones del grupo IO recibieron 10 ml/kg de IO (150 mg/kg) durante cinco semanas. Se observaron el peso corporal, el nivel de azúcar en sangre, la ingesta de alimentos, la ingesta de agua potable, la tolerancia a la glucosa y la tolerancia a la insulina de los ratones de cada grupo, y se estudiaron muestras de biopsias hepáticas, renales y pancreáticas mediante tinción de hematoxilina eosina.

Resultados:

los niveles de glucosa en sangre, el consumo de agua, la lipoproteína de baja densidad (LDL) y los triglicéridos (TG) disminuyeron después de la administración de IO. En comparación con el grupo HFD+STZ, el número de células β pancreáticas normales y la necrosis focal hepática disminuyeron significativamente en el grupo IO.

Conclusiones:

el IO redujo el nivel de glucosa en sangre, ayudó a recuperar el peso corporal y mejorar la sensibilidad a la insulina, la tolerancia a la insulina y la tolerancia a la glucosa en ratones diabéticos. Además, el IO revirtió el daño orgánico inducido por HFD y STZ. (AU)
