Heparine is used as a therapeutic anticoagulant.Research carried out in the last years showed in both in vivo and in vitro experiments (also in men), that this is a pleiotropic substance with many diverse activities.Immunoregulatory properties of heparine, including immunosupressive and most of all anto-proliferative lead to create the theory of its possible use in sevral chronic inflamatory processes.First experiments seem to justify this opinion.

The pseudo-cubic lattice parameters of rare-earth (RE) scandate, REScO_3, single crystals grown by the Czochralski technique with RE = Dy to Pr lie between about 3.95 and 4.02 Å. These crystals are the only available perovskite substrates in this lattice constant range that can withstand virtually any thin film growth conditions. Two members of this series, PmScO_3 and EuScO_3, are, however, not suitable for substrate applications. Because the pseudo-cubic lattice parameters between neighbouring REScO_3 compounds decrease with rising atomic number of the RE in about 0.01 Å steps, the unsuitability of PmScO_3 (radioactivity) and EuScO_3 (incompatibility with Si) causes an interruption in this lattice spacing sequence. To replace them, solid solutions of their adjacent rare-earth scandates, i.e., (Nd_{0.5}Sm_{0.5})ScO_3 and (Sm_{0.5}Gd_{0.5})ScO_3, were grown by the Czochralski method. Their average pseudo-cubic lattice parameters of 3.9979 Å and 3.9784 Å are very close to those of PmScO_3 and EuScO_3, respectively, and they show very low segregation. These qualities make these solid solutions excellent substitutes for PmScO_3 and EuScO_3.
