    Abstract:
    Male Japanese quail (Coturnix coturnix japonica), susceptible to cholesterol-induced atherosclerosis, were rendered hypercholesterolemic by feeding a diet containing 0.5% cholesterol in two experiments. Half the animals also received a dietary supplement of sodium nitroprusside ranging in concentration from 0.005% to 0.015%. After 10 weeks on the diets, serum was obtained for cholesterol analysis, the animals were killed, and the aortae removed and examined for the presence of atherosclerotic lesions. The number of animals having lesions and the severity of the lesions was reduced in a dose dependent manner among those animals receiving nitroprusside. Serum cholesterol was also reduced in response to increasing levels of dietary nitroprusside. These findings indicate that, in this model, dietary nitroprusside, a source of nitric oxide, can reduce the appearance and severity of atherosclerotic lesions in the aorta.
