Effect of samh seeds supplementation (Mesembryanthemum forsskalei Hochst) on liver enzymes and lipid profiles of streptozotocin (STZ)-induced diabetic Wistar rats

Thirty streptozotocin (STZ)-induced diabetic of Wistar Albino rats were divided into five groups. The rat groups received different food (natural diet or high fat content diet) supplemented with 10% or 15% of samh seeds for 6 weeks. At the end of the study, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phophatase (ALP) and lactate dehydrogenase (LDH) enzymes have been measured in diabetic rats liver. In addition, liver lipid profile (total cholesterol (TC), triglyceride (TAG), lipid peroxide production malondialdehyde (MDA)) and reduced glutathione (GSH) in have been measured in diabetic rats liver, and the levels of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) were also determined. The samh seeds diet supplemented with cholesterol significantly increase (P < 0.05) the levels of liver peroxide production MDA, TC and TG in diabetic rats comparing to the samh diet not supplemented with the cholesterol. However, the samh seeds significantly decrease (P < 0.05) the level of GSH. These data suggest that the samh seeds diet not supplemented with the cholesterol regulated C and TG metabolism and decrease the lipid peroxidation in the diabetic rats.
