Brain, hypothalamic and pituitary monoamines were measured in 90-day-old male rats after postnatal exposition to electromagnetic microwaves. The treatment decreased brain serotonin, increased brain 5-hydroxyindoleacetic acid and hypothalamo-pituitary catecholamines. The modifications observed in the levels of the monoamines were correlated with the(More)
An occurrence and a magnitude of alcoholic liver diseases depend on the balance between ethanol-induced injury and liver regeneration. Like ethanol, polyamines including putrescine, spermidine, and spermine modulate cell proliferation. Thus, the purpose of this study was to evaluate the relationship between effect of ethanol on hepatocyte (HC) proliferation(More)
Disappearance of plasma corticosterone after psychic aggression in the prepubertal Rat (25 days) is carried out in a similar manner in the two sexes. At this age, neonatal gonadectomy declined the rate of disappearance. In the adult Rat (60 days) disappearance of plasma corticosterone proceeds more rapidly in females than in males; neonatal gonadectomy(More)
1. The plasma corticosterone levels were measured in nursing female rats which had been removed from their pups for 12 hrs, at 9 a. m. every day till weaning (day 22). The mean value found in this condition (14.6 +/- 2.7 mug/100 ml) does not differ significantly from that found for the cyclic female (13.7 +/- 4.2 mug/100 ml). 2. Suckling for a period of(More)
Natural polyamines such as putrescine (Put), spermidine (Spd), and spermine (Spm), which are present in the human diet in large amounts, associated with their active transporter, are assumed to play a role in non-heme iron uptake and iron bioavailability from nutrients. Enterocytes and hepatocytes play pivotal roles in the regulation of body iron(More)
Evolution, during growth, of basal plasma concentration of corticosterone and the adrenocortical response to psychic aggression was studied in animals of both sexes, normal or gonadectomized on the day of birth. 1. In the control animals : (a) The fluctuations of the basal plasma concentration of corticosterone took a similar course in the male and female;(More)
