Insights
Boric acid (BA) supplementation may protect against fetal alcohol syndrome (FAS) by reducing oxidative stress in the cerebral cortex of newborn rats. This study shows BA
Area of Science:
- Neuroscience
- Toxicology
- Biochemistry
Background:
- Prenatal alcohol exposure is a leading cause of fetal alcohol syndrome (FAS).
- Alcohol exposure induces significant oxidative stress in the developing brain.
- The cerebral cortex is particularly vulnerable to alcohol-induced damage.
Purpose of the Study:
- To investigate the effects of boric acid (BA) on prenatal alcohol exposure.
- To assess BA's protective role against alcohol-induced oxidative stress in the cerebral cortex of rat pups.
- To evaluate BA's impact on key oxidative stress biomarkers.
Main Methods:
- Animal model: Pregnant rats exposed to alcohol, with or without BA supplementation.
- Biochemical assays: Measurement of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) in cerebral cortex tissue.
- Statistical analysis to compare groups.
Main Results:
- Alcohol exposure significantly increased MDA levels, indicating lipid peroxidation.
- Boric acid supplementation significantly decreased MDA levels in alcohol-exposed pups.
- Boric acid treatment significantly increased catalase (CAT) activity compared to alcohol-exposed group.
- Glutathione peroxidase (GPx) activity was decreased in the alcohol group.
Conclusions:
- Prenatal alcohol exposure causes oxidative damage to the cerebral cortex membranes in rat pups.
- Boric acid demonstrates potential antioxidant properties against alcohol-induced oxidative stress.
- BA supplementation may offer a protective effect in mitigating FAS-related neurotoxicity.
Abstract:
To the best of our knowledge, this is the first study concerning the effect of boric acid (BA) administration on fetal alcohol syndrome (FAS). In this study, the aim was to investigate prenatal alcohol-induced oxidative stress on the cerebral cortex of newborn rat pups and assess the protective and beneficial effects of BA supplementation on rats with FAS. Pregnant rats were divided into three groups, namely the control, alcohol and alcohol + boric acid groups. As markers of alcohol-induced oxidative stress in the cerebral cortex of the newborn pups, malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) levels were measured. Although the MDA levels in the alcohol group were significantly increased compared with those in the control group (P<0.05), the MDA level in the alcohol + boric acid group was shown to be significantly decreased compared with that in the alcohol group (P<0.01). The CAT activity of the alcohol + boric acid group was significantly higher than that in the alcohol group (P<0.05). The GPx activity in the alcohol group was decreased compared with that in the control group (P<0.05). These results demonstrate that alcohol is capable of triggering damage to membranes of the cerebral cortex of rat pups and BA could be influential in antioxidant mechanisms against oxidative stress resulting from prenatal alcohol exposure.
