NPC cells are seeded in 96-well plates (5000/well) and allowed to adhere for 24 h. The medium is then substituted by a fresh one containing different concentrations (0.01–10 µM) of osajin for another 24 h. For the time-course assay, the incubation times with 5 µM of osajin are 6, 12, 24, 36 and 48 h. After incubation, 10 µl of 5 mg/ml of MTT is added to each well and incubated for 4 h at 37°C. Cell viability is determined using the MTT-based assay^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Rats^[1]

The Wistar rats are divided into four groups. The first treatment group receives osajin (5 mg/kg/day in 0.5% Avicel); the second treatment group receives pomiferin (5 mg/kg/day in 0.5% Avicel); the placebo group receives only 0.5 Avicel; the last is an untreated control group. Biochemical indicator of oxidative damage-lipid peroxidation product malondialdehyde, antioxidant enzymes-superoxide dismutase, glutathione peroxidase, total antioxidant activity in serum and myocardium are evaluated. The effect of osajin and pomiferin on cardiac function, left ventricular end-diastolic pressure, left ventricular pressure and peak positive +dP/dt ischemia and reperfusion, also is examined^[1].
