The effect of low doses of echinochrome A (EchA), a natural polyhydroxy-1,4-naphthoquinone pigment from the sea urchin , has been studied in clinical trials, when it was used as an active substance of the drug Histochrome and biologically active supplement Thymarin. Several parameters of lipid metabolism, antioxidant status, and the state of the immune system were analyzed in patients with cardiovascular diseases (CVD), including contaminating atherosclerosis. It has been shown that EchA effectively normalizes lipid metabolism, recovers antioxidant status and reduces atherosclerotic inflammation, regardless of the method of these preparations' administrations.

Thymalin (Thymarin) and T-activin--thymic preparations of polypeptidic character--were used for influencing the parasitic infection in a model system mouse--Taenia crassiceps. A single subcutaneous application of 100 micrograms of Thymalin per mouse at the day of infection resulted in a decrease (by 54.9%) in the number of cysticerci in peritoneal cavity of experimental mice compared with the controls.

The virus-inhibiting effect for HIV was observed with interferon in doses of 10-100 IU/ml. At a concentration of interferon of 1000 IU/ml, virus replication was inhibited completely, the interferon doses used exerting no marked toxic or antiproliferative effect on the cells.

It was shown that as a result of thymectomy of adult animals the ability of bone marrow CFUs to form granulocytic colonies decreased and that of splenic CFUs to form erythroid colonies increased. The immunostimulating low-molecular-weight polypeptides, thymarin and cortexine , normalized the differentiation of CFUs from bone marrow and spleen but interfered with the formation of erythroid colonies from CFUs of peripheral blood of thymectomized mice.
