Mice treated for diabetes were given 100 mg/kg of M. oleifera extract orally. Glucose and insulin levels were tested to calculate insulin resistance. In addition, total antioxidant capacity (TAC) was also determined. Blood urea nitrogen (BUN) and creatinine. Relative concentrations of CD44 proteins were also measured by flow cytometry.
