To investigate the possible long-term consequences of gestational exposure to cannabinoids on cognitive functions, pregnant rats were administered with the CB1 receptor agonist WIN 55,212-2 (WIN), at a dose (0.5 mgkg) that causes neither malformations nor overt signs of toxicity. Prenatal WIN exposure induced a disruption of memory retention in 40- and(More)
F3/contactin (CNTN1) and TAG-1 (CNTN2) are closely related axonal glycoproteins that are differentially regulated during development. In the cerebellar cortex TAG-1 is expressed first as granule cell progenitors differentiate in the premigratory zone of the external germinal layer. However, as these cells begin radial migration, TAG-1 is replaced by(More)
Rats (Rattus norvegicus) produce ultrasonic calls during mating. We examined changes in the structure and pattern of such vocalizations over the ejaculatory series. In Experiment 1, vocalizations were recorded from 11 pairs of rats through 3 ejaculatory series and analyzed spectrographically. We classified 4 categories of call by spectral frequency and(More)
Wistar female rats were exposed to relatively mild concentrations of carbon monoxide (75 and 150 ppm) from day 0 to day 20 of pregnancy. The results show that prenatal exposure to CO (150 ppm) produced a significant reduction in the minimum frequency of ultrasonic calls emitted by rat pups removed from their nest. Moreover, a significant decrease in the(More)
OBJECTIVE The objective of this study was to compare cycle control, tolerability and sexual well-being with the use of three hormonal contraceptives. METHODS In this prospective randomized study, the effects of two combined oral contraceptives [20 microg of ethinylestradiol (EE)/100 microg of levonorgestrel and 15 microg of EE/60 microg of gestodene] were(More)
Primiparous pregnant Sprague-Dawley dams were administered a single daily s.c. injection of diazepam (0.1 and 1 mg/kg) or vehicle over gestation days 14-20. No differences in neonatal mortality and weight gain were found between the control and diazepam-exposed pups. Conversely, male pups prenatally treated with this benzodiazepine exhibited subtle(More)
Prenatal administration of typical (desipramine, DMI) and atypical (viloxazine, VX and mianserin, MS) antidepressants, at dose levels which do not influence reproductive success or neonatal mortality, produces subtle behavioural changes in offspring of treated rats. Physical signs, such as pinna detachment (unfolding of external ear) and eye opening, were(More)
Prenatal exposure to a dopamine receptor blocking agent such as haloperidol (given to the mother at a dose of 0.5 mg/kg s.c. from day 4 to day 15 of gestation) produced subtle behavioural changes in rat pups. Haloperidol decreased the rate of ultrasonic vocalization in 4-day-old male pups removed from the nest. The changes in ultrasonic emission elicited by(More)
In the treatment of depression fluoxetine [a selective serotonine reuptake inhibitor (SSRIs)] is a widely used drug in humans. The selectivity, efficacy, side effects and simplicity of dosage contributed to fluoxetine's clinical acceptance. Several psychiatric disorders (many of them responsive to SSRIs) are present during pregnancy; up to 10% of pregnant(More)
The neurofunctional effects of developmental alcohol exposure (3% v/v solution from day 15 of gestation to day 7 after parturition) have been investigated in Sardinian alcohol-preferring (sP) and alcohol-nonpreferring (sNP) rat lines, selectively bred for opposite alcohol preference and consumption. Alcohol exposure significantly decreased the rate of(More)
