The chronic inhalation toxicity and carcinogenicity of ethylene oxide (EO) and propylene oxide (PO) were evaluated in a 2-year inhalation bioassay. Five groups of male weanling Fischer 344 rats, 80 per group, were exposed at 0 ppm (shared control; filtered air), 50 ppm EO, 100 ppm EO, 100 ppm PO, or 300 ppm PO (7 hr/day, 5 days/week) for 104 weeks.

This report describes differences in motoric and instrumental activity of daily living skills (MADLs and IADLs) between 1,442 people with autism and 24,048 people with mental retardation, using data from an adaptive behavior measure. Comparisons were made using groups defined by age (5-12, 13-21, and 21-35 years) and intellectual level. Diagnoses of record(More)
Considerable controversy surrounds the continued use of restrictive behavioral procedures in the treatment of destructive behaviors, such as self-injury, aggression, and property damage, displayed by some people with mental retardation. This study reports on the extent that pharmacological and behavioral consequences occur in response to these behaviors(More)
Petroleum middle distillates (PMDs) elicit skin tumors in mouse epidermal carcinogenesis studies. The response is characterized by a long latency with only a small percentage of animals developing tumors. Although the carcinogenic activity of certain other petroleum hydrocarbons largely depends upon the presence of polycyclic aromatic hydrocarbons (PAHs),(More)
Forty-five horses were infected peripherally or intrathecally with enzootic or epizootic strains of Venezuelan equine encephalomyelitis (VEE) virus. Low titers of virus appeared in cerebrospinal fluid (CSF) after peripheral inoculation of enzootic or epizootic VEE virus strains. Intrathecal infection with either epizootic or enzootic VEE virus produced(More)
A variety of neoplastic and degenerative lesions were observed in 216 aged male breeder (to 24 months of age) and virgin ACI/segHapBR rats sacrificed from 24 to 40 months of age. The most common neoplasms were pheochromocytomas, pituitary tumors, interstitial cell tumors of the testis, and tumors of the skin and subcutis. Many rats had multiple endocrine(More)
