Pregnant Long-Evans rats were given a single i.p. injection of 30 mg/kg of methylazoxymethanol (MAM) acetate or saline on day 14 of gestation (vaginal plug = day 0). All litters were reduced to 8 at birth and were reared by their biological dams. Between 49-192 days of age all offspring were examined on open-field, figure-8 (at two different ages), and(More)
Changes in EEG and susceptibility to electrically induced seizures were examined in the ferret with lissencephaly produced by exposure to a single injection of methylazoxymethanol acetate (MAM Ac) given to the pregnant jill on gestation day 32. Ten lissencephalic and 11 normal ferrets were chronically implanted with 14 cortical stainless steel electrodes.(More)
Forty pregnant rats were given an IP injection of either 0, 14, 22, or 30 mg/kg of MAM on day 15 of gestation. One animal of each sex from each litter was tested between 80 and 90 days of age in a holeboard mounted on a stabilimeter. An additional animal of each sex from each litter was tested between 110 and 120 days of age in a two-way shuttle avoidance(More)
Treatment of pregnant ferrets with 15 mg/kg of methylazoxymethanol acetate (MAM) at 33 days of fetal gestation results in offspring with cortical hypoplasia and lissencephally. Neurochemical analysis of 5 areas of cortex from 8-week-old offspring of MAM- or vehicle-treated jills indicated an overall enrichment in markers for catecholaminergic (tyrosine(More)
A behavioral profile of the ferret is presented for those who would like to use this animal in behavioral teratology and toxicology, or other disciplines involving behavior. We have reviewed neurobehavioral teratology of lisencephalic ferrets and neuropsychology of ferrets sustaining frontal lesions, as well as most of the studies of "normal" ferret(More)
INTRODUCTION Developmental exposure to estrogens has been shown to affect the musculoskeletal system. Furthermore, recent studies have shown that environmental exposure to estrogen-like compounds is much higher than originally anticipated. The aim of this study was to determine the effects of diethylstilbestrol (DES), a well-known estrogen agonist, on(More)
