Comparative study of the effects of chondroitin sulfate isomers on atherosclerotic subjects.


Effects of isomers of chondroitin sulfate on atherosclerosis were clinically compared, based on sulfate linkage and the amount of sulfate, by using chondroitin 4-sulfate, chondroitin 6-sulfate and chondroitin polysulfate. Fourty eight age-matched atherosclerotic subjects were selected from a home for the elderly in order to the treatment with the agents. The isomers of chondroitin sulfate were given a daily dose of 4.5 g perorally. During the experimental period for 64 months, mortality, serum cholesterol, thrombus-formation time and thrombus weight were examined. The result obtained was as follows: mortality in the groups treated with the isomers of chondroitin sulfate was less than the age-matched untreated control group. Serum cholesterol value in the group treated by the isomers of chondroitin sulfate, chondroitin polysulfate group in particular, fell lower than the pre-treatment value. Thrombus formation time prolonged 150% in the group treated with chondroitin polysulfate over the untreated control group and the resultant thrombus weight was reduced in the treated group. Thus, these data indicated that the isomers of chondroitin sulfate are clinically effective on the treatment of atherosclerosis in the order of chondroitin polysulfate, chondroitin 4-sulfate and/or chondroitin 6-sulfate.
