Aortic inmmunohistochemical reaction of inducible nitric oxide synthase (iNOS) of normal groups [control (C), Moringa olifera seed oil extract (MC) and lycopene (LC)] showed lower expression of iNOS protein. The down chart expressed semi-quantitative analysis of immune-stained area % (ISA%) of iNOS. The high fat diet fed (HFD) induced obese group ( O) showed higher expression of iNOS protein. Administration of Moringa olifera seed oil extract (MO) and lycopene (LO) to HFD induced obese groups ameliorated the increased iNOS protein expression than HFD fed induced obese group.
