Gastric carcinoma: an unusual presentation
Reversible ischœmic colitis is usually associated with diffuse obliterative arterial disease. The case is presented of a patient who had a carcinoma of the stomach which had directly infiltrated the middle colic vessels and produced symptoms of colonic ischcemia. His method of presentation and subsequent progress are describe
Control of tumor growth in mice by thoracic duct drainage: relationship to blocking factor in lymph
Tumor‐specific blocking factors were detected by the macrophage migration inhibition technique, in thoracic duct lymph collected 24 to 48 h after transplantation of two methylcholanthrene‐induced tumors into mice. Drainage of lymph in this period, with replacement of the cells, inhibited subsequent tumor growth. Blocking factor was not found in lymph from mice with a third tumor, when examined at the same stage, and thoracic duct drainage did not affect tumor growth in this instance. The results indicate that blocking factor has a function in vivo and that decreasing its concentration in a tumor‐bearing host at a critical stage can suppress tumor growth
End thoracic duct pressures in man
Thoracic duct end pressures have been measured in a conscious patient undergoing cannula‐tion in an attempt to remove serum blocking activity. Pressures were measured during rest, coughing, straining and laughing, and during the last‐mentioned activity pressures of the order of 85 mm Hg were recorded. It is suggested that formal ligation of the thoracic duct would be necessary to withstand these pressures following removal of the cannula at the termination of treatment

Chinese Assimilation Across America: Spatial and Cohort Variations
Portes and Borocz's (1989) segmented assimilation framework argued that the assimilation of immigrants into American society does not necessarily or automatically lead to similarity and equality with the mainstream culture. Instead, endowed human capital, the nature of immigration, and reception contextualize the process and potentially lead to differential outcomes. Recognizing that spatial differences in assimilation may also exist, the segmented assimilation framework is extended within this paper to include a more explicit recognition of geography's role in shaping the assimilation trajectory. The empirical analysis draws upon the 1980 and 1990 PUMS data files, and compares the assimilation trajectory of Chinese immigrants (excluding Hong Kong and Taiwanese origins) across the New York, San Francisco, and Los Angeles metropolitan areas. Based upon period of arrival and age in 1980 and 1990, measures of assimilation are compared across these three metropolitan areas, along with the role of internal migration in maintaining or decreasing assimilation differences. The analysis indicates that the progress of assimilation varies significantly over space, with spatial differences in measures of assimilation persisting over time, despite the role of internal migration. Reasons as to why this occurs are presented in the conclusion. Copyright 2004 Gatton College of Business and Economics, University of Kentucky..
