OBJECTIVE To assess the hazards at an early phase of the growing epidemic of deaths from tobacco in China. DESIGN Smoking habits before 1980 (obtained from family or other informants) of 0.7 million adults who had died of neoplastic, respiratory, or vascular causes were compared with those of a reference group of 0.2 million who had died of other causes.(More)
A case-control study focusing on the role of single food items was undertaken in the Heilongjiang area, 241 patients with histologically verified stomach cancer and an equal number of controls (with non-neoplastic diseases) matched by age, sex and area of residence being interviewed during a 2-year period. Questions asked covered economic status,(More)
BACKGROUND From March 1986 through May 1991, we conducted a randomized nutritional intervention trial, the General Population Trial, in Linxian, China, a region with epidemic rates of squamous esophageal and adenomatous gastric cardia cancers. We found that participants who received selenium, beta-carotene, and vitamin E had significantly lower cancer(More)
We report 5 cases of chronic myelogenous leukemia (CML) and 1 case of acute myeloid leukemia (AML) with the dual presence of t(9;22) and inv(16). The 6 patients were 5 men and 1 woman with a median age of 42.5 years. All cases were BCR-ABL+ with p210 products detected in all CML cases and a p190 product detected in the AML case. An increase in bone marrow(More)
Infiltration of hematogenous lineage cells into the central nervous system (CNS) was investigated in the twitcher mouse, a murine model of globoid cell leukodystrophy in human. The hematogenous cells were selectively labeled following intraperitoneal injection of rhodamine isothiocyanate (RhIc). The frequency of detecting Rhlc-labeled cells (Rhlc+ cells) in(More)
The search for genes responsible for the sensitivity of human cells to cell-killing effects of UV is an important area of biological research. To identify candidate genes responsible for UV sensitization, levels of mRNA expression were compared between UV-sensitive RSa cells and UV-resistant variant UV(r)-1 cells, using a differential display method and(More)
Mechanisms of molecular responses of human cells to gravity change and/or space radiation are one of the most important physiological problems in space science. We have previously reported that expression levels of several genes are changed in cultured human cells after UVC irradiation, and a few of those genes are responsible for UVC sensitivity. In this(More)
Studies of arterialized capillary blood gases and acid-base values were performed on 712 normal persons who were between the ages of 29 days and 24 years. The results were divided for clinical use into six groups by age; linear regression lines were constructed for better understanding of the development of blood gas levels and the acid-base balance.
