Fetal Alcohol Syndrone (FAS) is a syndrome with characteristic abnormalities resulting from prenatal exposure to ethanol. In many children with FAS syndrome gross pathological changes in the heart are seen with septal defects the most prevalent abnormality recorded. Few studies in animal models have been performed on the effects of ethanol on heart development. In our laboratory, it has been observed that prenatal ethanol exposure of Swiss albino mice results in abnormal cardiac muscle ultrastructure when mice were examined at birth and compared to pairfed and normal controls. Fig. 1 is an example of the changes that are seen in the ethanol-exposed animals. These changes include enlarged mitochondria with loss of inner mitochondrial membrane integrity and loss of myofibrils. Morphometric analysis substantiated the presence of these alterations from normal cardiac ultrastructure. The present work was undertaken to determine if the pathological changes seen in the newborn mice prenatally exposed to ethanol could be reversed with age and abstinence.

ABSTRACT Mature female hamsters bearing subcutaneous polyacrylamide (PAA) implants, with ethinyloestradiol (EO), for at least 10 days prior to mating revealed: 0.5 and 2.5 mg EO in 7% PAA significantly disturb the timing of oestrus and mating, but have no apparent effect on rate of pregnancy, ovulation and implantation. 2.5 mg EO in 20 and 40% PAA conspicuously reduces the likelihood of pregnancy, although the occurrence of oestrus and mating are affected only slightly. Fertility in these hamsters was virtually restored, judging from pregnancy rates, when they were remated 11 days, or more, following removal of their implants (37 days after implantation), but significantly more foetuses were resorbed in these litters. From tissue sections of skin and muscle at the implant site, ovary, uterus, pituitary, adrenals and liver, PAA implants, without EO, cause no overt pathological changes in the bearer. Effects characteristic of oestrogen are present when these implants contain EO, and these include a conspicuous thickening of the epidermis and dermis; haemorrhagic lesions were also noted in the maternal placenta of animals with EO implants. There is an association between reproductive performance and the rate of EO release by an implant. A 7% PAA implant with 2.5 mg EO can release most of it within 2 days, and principally influences events (oestrus and mating) that precede the main target (pregnancy) of a 20% PAA implant, which releases the steroid over the longer interval of 7 days.

AbstractAlthough considerable research has been devoted to cognitive functions deteriorating due to diseases of cardiovascular system, rather less attention has been paid to their theoretical background. Progressive vascular disorders as hypertension, atherosclerosis and carotid artery stenosis generate most of all pathological changes in the white matter, that cause specific cognitive disorder: disconnection syndromes, and disturbances in the dynamic aspect of information processing. These features made neuropsychological disorders secondary to cardiovascular diseases different than the effects of cerebral cortex damage, which may be interpreted modularly.
