The histologic types of lung cancer in 855 patients (747 men and 107 women) from three hospitals and one international study of insulation workers were evaluated. Of these, 196 cases had asbestos exposure. About one half of the cases were diagnosed from surgical slides and one half from autopsy slides. Squamous cell carcinoma constituted the largest(More)
In a case-control study in 4 hospitals from 1971 to 1981, 134 cases of lung cancer and 402 cases of colon-rectum cancer (the controls) were identified in nonsmoking women. All cases and controls were confirmed by histologic review of slides, and nonsmoking status and exposures were verified by interview. Odds ratios (OR) increased with increasing number of(More)
The purpose of this study was to examine the difference between subjective refraction and autorefraction for different age groups. We call the difference (autorefraction minus subjective refraction) the excess of autorefraction over subjective refraction or the autorefractive excess. Five age groups of 50 subjects each were used. Subjects in group 1 were(More)
Ecological networks (ENs) of indigenous vegetation among commercial forestry plantations have been implemented to offset the negative effects of the alien plantation trees on local biodiversity. However, it is not known whether these ENs are equivalent to protected areas (PAs) in terms of their grassland biodiversity. To address this knowledge gap, we(More)
A study was conducted to compare the analgesic activity of single oral doses of etodolac (25, 50, 100, 200, and 400 mg) with 650 mg aspirin and placebo. A total of 146 patients with moderate or severe pain from orthopedic or urologic interventions received one of the test medications 13-25 h after the beginning of surgery and according to a randomized(More)
Live (diluted) and inactivated rabies vaccines of low antigen content induce early and enhanced death in mice, inoculated before vaccination with a wild type of rabies virus. Such vaccines, which neither induce interferon nor protect, produce a low level of antibodies which appear later than with vaccines of higher antigenicity. It is recommended to examine(More)
Five out of seven American woodchucks inoculated with woodchuck hepatitis virus developed antigenemia after 2 to 13 weeks followed by an antibody response. One animal became a carrier, and another animal exhibited a primary antibody response. Clinical disease was not obvious and aminotransferase elevation could not be demonstrated. Liver biopsy showed(More)
