OBJECTIVE To establish diagnostic accuracy and reproducibility of a diagnosis of cervical intraepithelial neoplasia 3 (CIN 3) in menopausal women on routinely stained hematoxylin and eosin (H&E) slides and compare it to slides processed for p16 and Ki-67. MATERIALS AND METHODS Confirmed cases of CIN 3 and benign atrophic changes were reviewed(More)
Amygdalotomized, sham-operated and intact wild-derived house mice of both sexes were group-caged (8-10) or singly caged for 3 weeks. The weights of ovaries (p is less than 0.05) and uteri (p is less than 0.01) were less in intact and sham-operated grouped females compared to singly caged intact and amygdalotomized females. The weight of the reproductive(More)
A colony of NZW rabbits was developed in which 18 of 126 members exhibited overt symptoms of diabetes mellitus. On the basis of total body weight measurements, obesity does not appear to play a primary role in the development or manifestation of the syndrome. The relatively high frequency of occurrence of spontaneous diabetes mellitus in this colony seems(More)
We have developed an interactive statistical quality-control system for the small- to medium-sized radioimmunoassay laboratory, which can be used in a programmable desk-top calculator instead of the medium- or large-scale computer systems usually required. The design of this quality-control system is modeled after the suggestions of Rodbard and has three(More)
The biaryl amine benzidine has been reported to produce tumors of the bladder in both man and animals. We have developed and validated a radioimmunoassay (RIA) procedure for monitoring potential human exposure to benzidine through detection in urine samples of one of its known urinary metabolites. The antibody used in the assay was produced in rabbits and(More)
As the numbers and production of environmental pollutants and hazardous industrial compounds increase, the necessity for monitoring the environment and workplace to avoid or to limit human exposure to toxic substances becomes more urgent. In support of the occupational safety program at the National Center for Toxicological Research, very sensitive and(More)
The synthetic chemical 4-aminobiphenyl (4-ABP) has been shown to be a bladder carcinogen in both man and animals. A valid radioimmunoassay for a metabolite of 4-ABP has been developed as a means to monitor potential human exposure to 4-ABP. The antibody was produced by the immunization of two female New Zealand White rabbits and was found to be highly(More)
