The result, that we could further ver ify at this tine let us express the following theory: Except UCC 006214 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.

As of 1974, the United States was consuming more than 767,000 tons of asbestos annually,16 which were used in as many as 5,000 separate consumer and industrial products.11 * * It has been known for decades that exposure to high levels of asbestos could lead to progressive pulmonary disease (asbestosis).11 By the 1970s, asbestos also was recognized widely as a human carcinogen, shown by epidemiological studies to produce mesothelioma, lung cancer, and perhaps other malignancies.1* Evidence available to EPA suggested that as many as 10,000 people annually were dying from past exposure to asbestos fibers, mostly resulting from asbestos insulation products used in shipbuilding during World War II and the Korean War and thereafter during the postwar construction boom.14 * It was against this background that EPA in 1979 launched a joint proceeding with the Consumer Product Safety Com mission to ban, phase out, or otherwise regulate some or all of the many hundreds of commercial uses for asbestos.16 Even before EPA's proceeding had begun, however, the commercial realities regarding asbestos use had begun to change.
