Effect of Corn Silk on Adipose Tissues in Type 2 Diabetic Rats Based on GC-MS
To evaluate the regulation effect of corn silk on fatty acid compositions in adipose tissues of rats with type 2 diabetes mellitus(T2DM) based on gas chromatography-mass spectrometry (GC-MS), and explore the mechanism of corn silk water decoction for lipid metabolism disorder in .
Method
2
Rat model of T2DM was established by high-sugar and high-fat diet combined with intraperitoneal injection of 35 mg·kg
-1
streptozocin (STZ). They were randomly divided into model group,metformin group,and low,medium and high dose groups(5.4,10.8,21.6 g·kg
-1
) of corn silk decoction, with administration of 4 weeks. Serum was taken from the abdominal aorta for the determination of free fatty acids (FFAs),blood lipids [total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL-C),low density lipoprotein(LDL-C)],and adipose tissue was taken for pathological section analysis. At the same time,GC-MS technology and multivariate statistical analysis methods were adopted to investigate the fatty acid compositions in adipose tissue.
Result
2
After treatment with corn silk decoction,the contents of FFAs,TC,TG,HDLC and LDLC in T2DM rats were all reversed. As compared with the model group,the morphology of rat adipocytes,macrophage infiltration,vascular congestion and other phenomena were restored after administration. GC-MS analysis showed that the contents of palmitic acid and stearic acid in the adipose tissue of T2DM rats were significantly increased,while the contents of tetradecanoic acid,pentadecanoic acid,9-octadecenoic acid,9-hexadecenoic acid and 5,8,11,14-eicosatetraenoic acid were decreased significantly,and all the dose groups of corn silk had a reversing effect on differentially expressed fatty acids.
Conclusion
2
Corn silk can be able to reverse the fatty acid content in adipose tissue and restore the morphology of adipose tissue,with a regulating effect on the lipid metabolism disorder in T2DM rats.
