We studied the effects of plant extracts and products of their biological treatment on trans-sialidase activity in human blood plasma. Extracts of kelp, fucus, yarrow, Saint John's wort, onion, and honey in vitro decreased trans-sialidase activity. Extracts of pollen (beebread) and garlic powder produced the maximum inhibitory effect. trans-Sialidase activity of blood plasma ex vivo decreased 2-fold after peroral administration of pollen and garlic powder. A correlation was found between the decrease in trans-sialidase activity in blood plasma and ability of blood plasma to induce cholesterol accumulation in cultured cells from the intact human aortic intima.
