The subclass of triglyceride -rich lipoproteins - remnant -like particles (RLP) seems to be strong and independent risk factor for cardiovascular disease. We eva luated the role of RLP and other risk factors (RF) with sonographically measured intima - media thickness of carotid arteries (IMT CCA) in a cohort of Czech population including women defined according to the time after menopause. We investigated relation of IMT CCA to age, weight, central obesity, plasma lipids including remnant -like particles cholesterol (RLP -C) and triglycerides (RLP -TG) in 136 men and 160 women. Using multiple linear regression analysis, significant association between IMT CCA and RLP -C was found in women 1 -7 years after menopause. In the whole group of women, only age and fasting blood glucose were independently associated with IMT CCA. In men only age significantly correlated wit h IMT CCA. Significant decrease of all plasma lipids betwe en 1988 and 1996 in men was detected, while in women significant increase in triglycerides and no change in non -HDL cholesterol was observed. RLP -C was the strongest independent RF for atherosclerosis in postmenopausal women but its as sociation with IMT CC A was limited to several years after menopause. In conclusion, women changing reproductive status could be more sensitive to atherogenic impact of remnant lipoproteins., J. Piťha, J. Kovář, Z. Škodová, R. Cífková, P. Stávek, L. Červenka, T.

The first experimental model of atherosclerosis (in rabbits) is more than hundred years old. Several animal species have bee n used to produce hyperlipoproteine mia and possible atherosclerosis. The gene manipulation produced the most used models recently. This review acknowledges the extensive study of atherosclerotic changes in experimental models of hyperlipoprotein emia and at herosclerosis to come to light thus far and the purpose here is not only to summariz e the published data but also to try to add some details of our experience in using these models. In addition to rabbit (the old but also improved model by reno-vascular hy pertension) dog, birds, pig, hamster, mice, rat and non-human primate’s animal models are described. The gene manipulation produced the most used models two decades ago. Germline genetically engineered (without apoE or LDL receptor genes) animals have beco me the most used models producing atherosclerotic changes in the aorta. Recent new models also producing atherosclerotic changes but without germline genetic manipulation are also described., R. Poledne, L. Jurčíková-Novotná., and Obsahuje bibliografii
