Abstract
Type 2 diabetes is a group of metabolic diseases mainly characterized by chronic hyperglycemia. Diabetic kidney disease is the most common microvascular complication of diabetes.
The aim of this study was to investigate the therapeutic effect of Isaria felina mycelium powder (IFMP) on diet and streptozotocin (STZ)-induced diabetic mouse model. And we analyze the main chemical constituents of Isaria felina mycelium powder.
The main chemical constituents of the alcohol-soluble IFMP were prepared and identified by high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (HPLC-Q-TOF-MS). The fasting blood glucose and renal index of the mouse model was determined. Serum levels of triglyceride (TG), total cholesterol (TC), serum creatinine (Scr) and blood urea nitrogen (BUN) were detected. The levels of CD2AP and nephrin proteins in the kidney were detected by ELISA kits.
A total of 32 compounds were identified, including nucleosides (16 types), amino acids (13 types), sterols (one type) and glycosides (two types). The experimental results showed that compared with the diabetes model group, IFMP reduced fasting blood glucose, food intake and water intake. Biochemical analysis indicated that IFMP reduced the serum levels of TG, TC, BUN and Scr, and increased the levels of CD2AP and nephrin proteins in the kidneys.
Therefore, IFMP has the potential to treat diabetes and prevent kidney damage induced by hyperglycemia.
期刊介绍：
Chinese Journal of Analytical Chemistry(CJAC) is an academic journal of analytical chemistry established in 1972 and sponsored by the Chinese Chemical Society and Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. Its objectives are to report the original scientific research achievements and review the recent development of analytical chemistry in all areas. The journal sets up 5 columns including Research Papers, Research Notes, Experimental Technique and Instrument, Review and Progress and Summary Accounts. The journal published monthly in Chinese language. A detailed abstract, keywords and the titles of figures and tables are provided in English, except column of Summary Accounts. Prof. Wang Erkang, an outstanding analytical chemist, academician of Chinese Academy of Sciences & Third World Academy of Sciences, holds the post of the Editor-in-chief.
