TNF and diabetes mellitus: As abnormal liver morphology and function under uncontrolled diabetes are usually due to fatty changes in the diabetic liver, we investigated the effect of ALA on hepatic structure and function following induction of T2DM by performing liver histology, liver function test (ALT, AST, ALP, total bilirubin), and by determining hepatic lipid profile (triglyceride, total cholesterol, FFA, LDL and HDL), inflammation (IL-1β; IL-6 and TNF-α) and antioxidant status (MDA, GSH and SOD).
