We report on a 70-year-old woman with diffuse normolipemic plane xanthoma (DNPX) who developed macular yellowish patches on the eyelids, both cheeks, and the nose. Histology revealed the accumulation of CD68-positive foam cells and Touton giant cells in the superficial dermis. Plasma lipid levels were within normal limits. The patient had no underlying hematological diseases. Her extensive lesi...

The susceptibility of low-density lipoprotein (LDL) to oxidation was studied in hypertriglyceridemic men (5 with type III and 5 with type IV) at baseline on a low-saturated-fat, low-cholesterol diet, after 6 weeks of dietary supplementation with fish oil (Promega, 12 g/d), and after 6 weeks of fish oil combined with probucol (500 mg BID). The relative content of n-3 polyunsaturated fatty acids ...

To investigate the effects of probucol on the treatment of spinal cord injury in rat, 80 rats were randomly divided into two groups of 40: a group treated with probucol and a control group. Allen's method was used to establish a rat model of spinal cord injury. After establishment, probucol (500 mg·kg(-1)·day(-1)) was intraperitoneally injected into the treatment group rats for 1 week, while th...

Apoptosis has been suggested to participate in stabilizing cell number in restenosis. Salvia miltiorrhiza (SM) Bunge which is a Chinese herb widely used for the treatment of cardiovascular disorders contains a potent antioxidant, Salvianolic acid B. To determine whether the antioxidant affects vascular apoptosis, the present study examined the frequency of apoptotic cell death in atheroscleroti...

In this study, we questioned whether in vivo probucol could prevent the progression of atherosclerosis in homozygous Watanabe heritable hyperlipidemic (WHHL) rabbits, an animal model for familial hypercholesterolemia. At 2 months of age, eight WHHL rabbits were divided into two groups. Group A (n = 4) was fed standard rabbit chow for 6 months. Group B (n = 4) was fed standard rabbit chow contai...

BACKGROUND Oxidative stress is the major etiopathological factor in adriamycin-induced cardiotoxicity. Relatively low amounts of endogenous antioxidant makes the heart vulnerable to oxidative stress-induced damage. Chronic oral administration of garlic has been reported to enhance the endogenous antioxidants of heart. We hypothesized that garlic-induced enhanced cardiac antioxidants may offer p...

Advanced glycation end products (AGEs) play important roles in the development of ocular complications in diabetes mellitus. Spontaneously Diabetic Torii (SDT) rats have marked hyperglycemia and severe ocular complications. We evaluated the effect of anti-AGE agents, aminoguanidine and pyridoxamine, and an antioxidant, probucol, on the development of diabetic retinopathy (DR) and cataract in SD...

To determine whether probucol's ability to confer antioxidant protection to low density lipoprotein (LDL) could be dissociated from its ability to lower high density lipoprotein (HDL) cholesterol, 17 hypercholesterolemic patients were treated with either a standard dose, 1 g/day (4 tablets), or a low dose, 250 mg/day (1 tablet), of probucol for a 6-month period. Effects of therapy on lipoprotei...

Intimal hyperplasia is a persistent problem after implantation of prosthetic grafts. Although the mechanisms underlying this hyperplastic response are unknown, it has been proposed that such responses may be due to chronic vascular injury similar to that of atherogenesis. Thus, the role of oxidation was explored using the potent antioxidant drug probucol. Adult New Zealand White rabbits fed a m...
