    Abstract:
    We investigated the effect of probucol (PB) on atherosclerosis in streptozotocin (SZ)-induced diabetic-hyperlipidemic APA hamsters in three different stages, the early, middle and late stages of atherosclerosis. Male APA hamsters were injected intraperitoneally with SZ or vehicle alone (citrate buffer; CB) as a control at the age of 8 weeks. At 6 weeks after injection (WAI) of SZ or CB (the early stage), 14 WAI (the middle stage) and 26 WAI (the late stage), animals were assigned to PB treated- or non-treated groups (CBPB, SZPB, CB, SZ). After 8 weeks of PB administration with diet, the aorta was taken from each animal for assessment of atheromatous lesions and blood samples were subjected to serum biochemical analysis and the measurement of blood lipid peroxide (LPO). In the middle stage, PB treatment significantly decreased serum total cholesterol level, slightly decreased LPO, and also tended to reduce the lesion area, although no statistical difference was seen. There was no marked effect of PB treatment in the early and late stages. These findings suggest that single use of PB has little effect on atherosclerosis of a hyperglycemia-hyperlipidemia animal model.
