| Abstract | ||||
| The present study aimed to investigate the possible hypoglycemic and hepatoprotective effects of saffron extract (100mg/kg b.wt) and fenugreek supplementation (1.4 g/day/kg b.wt) in STZ- induced diabetic rats at biochemical, histological, histochemical and ultrastructural levels. The results indicated that a single dose of STZ (50 mg /kg b wt, i.p) caused a significant increase in serum and liver total lipids, total cholesterol and triglyceride as well as serum low density and a very low density lipoprotein, accompanied by an increase in serum glucose level and oxidative stress marker, malondialdehyde and hydrogen peroxide level as well as serum aspartate and alanine aminotransferase activities. The results also reported a significant decrease in the high density lipoprotein, serum and liver total protein, serum albumin and globulin contents and A/G ratio, as well as a significant decrease in serum insulin level and the liver enzyme activities and the hepatic glutathione content. Histologically, STZ treated group showed degenerative changes in the pancreas and alteration in the structural integrity of the hepatocytes and their intracellular organelles. Histochemically, liver sections of STZ treated animals displayed marked decrease in the glycogen and total protein contents. On the other hand, the intake of saffron or fenugreek minimize the disturbance observed in the most tested parameters resulted from STZ administration and improve the liver structure and functions. Finally, it can be concluded that the intake of natural product such as saffron or fenugreek may be effective in reducing the diabetic liver injury induced by streptozotocin and the fenugreek supplementation showed more amelioration than saffron extract. | ||||
