Abstract

Background It is well documented that biologically active components of microalgae can be utilized for treatment of different diseases. This study was conducted to evaluate the antihyperglycemic and antihyperlipidemic activities and weight control of Nannochloropsis oculata microalgae (NOM) in Streptozotocin-induced diabetic male rats. Methods Diabetes was induced by intraperitoneal administration of Streptozotocin (55 mg/kg). Healthy and diabetic rats were divided in to six groups. Healthy and diabetic rats orally received distilled water or NOM (10 and 20 mg/kg) for three weeks. Results Oral administration of NOM to diabetic rats significantly reduced the serum concentrations of glucose, cholesterol, triglycerides, LDL and increased the serum concentration of insulin and HDL-C (P<0.05). Treatment with NOM had no significant effect on blood parameters in healthy rats (P>0.05). Also, NOM maintained body weight in diabetic rats (P<0.05). Conclusion It can be concluded that NOM has antihyperglycemic and antihyperlipidemic activities in diabetic rats.

  • Our findings show that the serum concentrations of glucose, insulin, triglycerides, cholesterol, LDL-C and HDL-C were not influenced by NOM administration in healthy rats (Tables 3 and 4; P>0.05)
