Curcuma longa modulates Islet ?-cell function and insulin resistance in diabetic rat..
Professional Med J Jan ;29(7):1084-8.

Objective: To analyze modulating effect of Curcuma longa on Pancreatic Islet β-cell function and insulin resistance in alloxan induced diabetic rat model. Study Design: Experimental study. Setting: Department of Anatomy, Pharmacology and Pathology, SRMCH, T. Adam. Period: February 2019 to January 2020. Material & Methods: One hundred adult male rats were selected according to criteria and grouped A to E. Group A and B was negative and positive control rats, and C –E were diabetic experimental rats. Alloxan (120 mg/Kg body weight) was injected intraperitoneally (i.p) to induce diabetes mellitus. Curcuma longa was used in doses of 200, 300 and 500 mg/d for 28 days. Body weight, blood glucose, HbA1c, insulin and C-peptide were estimated. Insulin resistance (HOMA-IR) and β- cell function (HOMA-β) were calculated by formulae. Data was analyzed on SPSS package ver. 21.0 (IBM, incorporation, USA) (p≤ 0.05). Results: Twenty eight days therapy of Curcuma longa extract ameliorates blood glucose, A1C, serum Insulin levels and C-peptide levels. Insulin resistance (HOMA-IR) was found improved and β- cell function (HOMA-β) was augmented in in Curcuma longa treated experimental rats (P=0.0001). Conclusion: Administration of Curcuma longa positively modulates the Islet β-cell function and insulin resistance in alloxan induced diabetic rats.
