In this study we used anionic living polymerization to prepare two different homopolymers: a poly(methyl methacrylate) (PMMA) and a PMMA derivative presenting polyhedral oligomeric silsesquioxane (PMA-POSS) units as its side chains. We then employed differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy, and wide-angle X-ray(More)
We present a patient with Henoch-Schoenlein purpura who had extremely low number of OKT4 positive T lymphocytes. However his lymphocytes responded normally to Leu3a and Coulter T4, which are also monoclonal antibodies that react with CD4 epitope. In vitro lymphocyte function tests revealed that helper-inducer T cell functions were normal. From these(More)
extends on the wall of the thorax. The animals were sacrificed between 25 and 157 days after transplantation. For histological examinations the material was fixed in Bouin's solution, and slices of 5 gm were stained with hematoxylin and eosin. Secretion of hGH of the transplanted human fetal pituitaries was assayed in plasma of the mice by a double antibody(More)
