Furthermore, were true substitutes available, it would take three to four years to complete the necessary research and development leading to the required changes in product, process and equipment design, as well as the actual delivery and installation of new plant and equipment in order to make non-PVC "equivalent" products available on a commercial scale.

The result, that we could further ver- / ify at this time let us express the following theory: Except DTH 00001688 7 for the slightly toxic alterations of the liver cells, this results from the expansion of the connective tissues in the portal system into the diffuse circulation in the liver* In advanced stages this leads to an interhepatic block (most like ly because of the hinderances in the height of the portal system, possibly similar to a sinusoidal block), with esophagus varices* It remains to be found if the splenomegaly is only is a secondary condition or if this primarily the direct result .
