The Combined Effects of Perinatal Ethanol and Early-Life Stress on Cognition and Risk-Taking Behavior through Oxidative Stress in Rats. Neurotox Res 2022; 40:925-940. [PMID: 35507233 DOI: 10.1007/s12640-022-00506-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 04/07/2022] [Accepted: 04/09/2022] [Indexed: 11/29/2022]
Abstract
Both prenatal ethanol and early-life stress have been shown to induce reduced risk-taking and explorative behavior as well as cognitive dysfunction in the offspring. In this study, we examined the effect of combined exposure to ethanol and early stress on maternal care, exploratory behavior, memory performances, and oxidative stress in male offspring. Pregnant rats were exposed to ethanol (4 g/kg) from gestational day (GD) 6-to postnatal day (PND) 14 and limited nesting material (LNS) from PND0-PND14 individually or in combination. Maternal behavior was evaluated during diurnal cycle. The level of corticosterone hormone and markers of oxidative stress were evaluated in the pups. Risk-taking and explorative behavior were assessed with the elevated-plus maze (EPM) test and cognitive behavior with the Morris water maze (MWM), novel object recognition (NORT), and object location memory (OLM) tests. In the mothers, perinatal alcohol or LNS either alone or in combination decreased maternal behavior. In the offspring, the combination of the two factors significantly increased the pup's plasma corticosterone concentration in comparison with ethanol and LNS alone. Reduced risk-taking behavior was observed in the ethanol, LNS and ethanol + LNS groups compared with the control group, and this was amplified in the co-exposure of ethanol and LNS groups. The MWM, NORT, and OLM tests revealed spatial and recognition memory impairment in the ethanol and LNS groups. This impairment was more profound in the co-exposure of ethanol and LNS. Also, we observed a significant decrease in superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities and an increase in malondialdehyde (MDA) level in the hippocampus of ethanol and LNS co-exposed animals as compared with individual exposure of ethanol and LNS. While each factor independently produced similar outcomes, the results indicate that the dual exposure paradigm could significantly strengthen the outcomes.

Abstract
Objective: Alcohol exposure during pregnancy affects the developing fetus and causes a variety of physical and neurological abnormalities. Here we aim to study the effects of vitamin E on spatial learning and memory deficits and on changes in hippocampal brain-derived neurotrophic factor (BDNF) levels following perinatal ethanol exposure in rats. Method: Pregnant Wistar rats received ethanol (4 g/kg) and vitamin E (doses of 100, 200, and 400 mg/kg) on day 0 of gestation (GD) until weaning (28 days). On postnatal days (PND) 29, the performance of spatial learning and memory of rats were measured using the Morris water maze (MWM). The expression of BDNF protein levels in the hippocampus was assayed using BDNF ELISA kits. Results: Ethanol exposed group showed higher escape latency during training, reduced time spent in the target quadrant, higher escape location latency and average proximity in probe test. Vitamin E with doses of 100, 200 and 400 mg/kg significantly reduced escape latency during training. Also, vitamin E (400 mg/kg) significantly increased time spent in target quadrant, decreased escape location latency and average proximity in probe test. Maternal ethanol treatment significantly reduced the expression of BDNF protein in the hippocampus of offspring, whereas administration of vitamin E (400 mg/kg) significantly increased hippocampal BDNF in ethanol-treated rats. Discussion: Vitamin E administration dose-dependently ameliorate learning and memory deficits induced by perinatal ethanol exposure and increased hippocampal BDNF levels. BDNF may be implicated in the beneficial effects of vitamin E on learning and memory in the perinatal ethanol-exposed rat.

Abstract
Apart from the genetically engineered, modified, strains of rabies virus (RABV), unmodified ‘fixed’ virus strains of RABV, such as the ‘French’ subtype of CVS11, are used to examine synaptically connected networks in the brain. This technique has been shown to have all the prerequisite characteristics for ideal tracing as it does not metabolically affect infected neurons within the time span of the experiment, it is transferred transneuronally in one direction only and to all types of neurons presynaptic to the infected neuron, number of transneuronal steps can be precisely controlled by survival time and it is easily detectable with a sensitive technique. Here, using the ‘French’ CVS 11 subtype of RABV in Wistar rats, we show that some of these characteristics may not be as perfect as previously indicated. Using injection of RABV in hind limb muscles, we show that RABV-infected spinal motoneurons may already show lysis 1 or 2 days after infection. Using longer survival times we were able to establish that Purkinje cells may succumb approximately 3 days after infection. In addition, some neurons seem to resist infection, as we noted that the number of RABV-infected inferior olivary neurons did not progress in the same rate as other infected neurons. Furthermore, in our hands, we noted that infection of Purkinje cells did not result in expected transneuronal labeling of cell types that are presynaptic to Purkinje cells such as molecular layer interneurons and granule cells. However, these cell types were readily infected when RABV was injected directly in the cerebellar cortex. Conversely, neurons in the cerebellar nuclei that project to the inferior olive did not take up RABV when this was injected in the inferior olive, whereas these cells could be infected with RABV via a transneuronal route. These results suggest that viral entry from the extracellular space depends on other factors or mechanisms than those used for retrograde transneuronal transfer. We conclude that transneuronal tracing with RABV may result in unexpected results, as not all properties of RABV seem to be ubiquitously valid.

Abstract
Fetal alcohol spectrum disorder (FASD) is estimated to occur in 1 % of all live births. The developing cerebellum is vulnerable to the toxic effects of alcohol. People with FASD have cerebellar hypoplasia and developmental deficits associated with cerebellar injury. Choline is an essential nutrient, but many diets in the USA are choline deficient. In rats, choline given with or following alcohol exposure reduces many alcohol-induced neurobehavioral deficits but not those associated with cerebellar function. Our objective was to determine if choline supplementation prior to alcohol exposure would ameliorate the impact of ethanol on a cerebellar-associated behavioral test in mice. Pregnant C57Bl6/J mice were maintained on a choline-deficient diet from embryonic day 4.5. On postnatal day 1 (P1), pups were assigned to one of eight treatment groups: choline (C) or saline (S) pre-treatment from P1 to P5, ethanol (6 g/kg) or Intralipid(®) on P5, C and or S post-treatment from P6 to P20. On P30, balance and coordination were tested using the dowel crossing test. Overall, there was a significant effect of treatment and females crossed longer distances than males. Ethanol exposure significantly reduced the total distance crossed. Choline pre-treatment increased the distance crossed by males, and both pre- and post-treatment with choline significantly increased total distance crossed for females and males. There was no effect of choline on Intralipid®-exposed animals. This is the first study to show that choline ameliorates ethanol-induced effects on balance and coordination when given before ethanol exposure. Choline fortification of common foodstuffs may reduce the effects of alcohol.

Abstract
Dendritic spines are the main postsynaptic sites of excitatory connections of neocortical pyramidal neurons. Alterations of spine shape, number, and density can be observed in different mental diseases, including those caused by developmental alcohol exposure. Pyramidal neurons of layer 2/3 are the most abundant cells of the neocortex and represent the main source of associative cortico-cortical connections. These neurons are essential for higher functions mediated by the cortex such as feature selection and perceptual grouping. Furthermore, their connections have been shown to be altered in experimental models of fetal alcohol spectrum disorders. Here, we used a Golgi-like tracing method to study the spine density of layer 2/3 associative pyramidal neurons in the somatosensory cortex of adult rats exposed to alcohol during the first postnatal week. The main result of the present study is represented by the decreased spine density in the apical dendrite of alcohol-treated rats, as compared to controls. As to the basal dendritic tree, there were no significant differences between the experimental and the control group. A decreased density of dendritic spines in the apical dendrite may impair the excitatory input onto pyramidal neurons, thus resulting in a widespread alteration of the cortical information flow.

Abstract
OBJECTIVE The present study aimed at investigating the effects of curcumin on the motor coordination and the estimate of the total number of cerebellar Purkinje cells of adolescent Wistar rats exposed to ethanol. METHODS The total of 21 male Wistar rats aged 37 d old were divided into three groups, namely ethanol, ethanol-curcumin, and control groups. The ethanol group received 1.5 g/kg ethanol injected intraperitoneally and water given per oral; the ethanol-curcumin group received 1.5 g/kg ethanol injected intraperitoneally and curcumin extract given per oral; the control group received saline injection and oral water. The treatment was carried out daily for one month, after which the motor coordination performance of the rats was examined using revolving drum apparatus at test days 1, 8, and 15. The rats were finally sacrificed and the cerebellum of the rats was further processed for stereological analysis. The estimate of the total number of Purkinje cells was calculated using physical fractionator method. RESULTS The ethanol-curcumin group performed better than both ethanol and control groups in the motor coordination ability at day 8 of testing (P< 0.01). No Purkinje cell loss was observed as a result of one month intraperitoneal injection of ethanol. CONCLUSION Curcumin may exert beneficial effects on the motor coordination of adolescent rats exposed to ethanol via undetermined hormetic mechanisms.

Long-lasting distortion of GABA signaling in MS/DB neurons after binge-like ethanol exposure during initial synaptogenesis. Brain Res 2013; 1520:36-50. [PMID: 23685190 DOI: 10.1016/j.brainres.2013.04.054] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2013] [Revised: 04/22/2013] [Accepted: 04/30/2013] [Indexed: 12/30/2022]
Abstract
Using a well-established model of binge-like ethanol treatment of rat pups on postnatal days (PD) 4-9, we found that maturation of GABAA receptor (GABAAR) miniature postsynaptic currents (mPSCs) was substantially blunted for medial septum/diagonal band (MS/DB) neurons in brain slices on PD 11-16. Ethanol reduced mPSC amplitude, frequency, and decay kinetics, while attenuating or exaggerating allosteric actions of zolpidem and allopregnanolone, respectively. The impact of ethanol in vivo was long lasting as most changes in MS/DB GABAAR mPSCs were still observed as late as PD 60-85. Maturing MS/DB neurons in naïve brain slices PD 4-16 showed increasing mPSC frequency, decay kinetics, and zolpidem sensitivity that were nearly identical to our earlier findings in cultured septal neurons (DuBois et al., 2004, 2006). These rapidly developing mPSC parameters continued to mature through the first month of life then stabilized throughout the remainder of the lifespan. Finally, equivalent ethanol-induced alterations in GABAAR mPSC signaling were present in MS/DB neurons from both male and female animals. Previously, we showed ethanol treatment of cultured embryonic day 20 septal neurons distorts the maturation of GABAAR mPSCs predicting that early stages of GABAergic transmission in MS/DB neurons are vulnerable to intoxication injury (DuBois et al., 2004, 2006). Since the overall character, timing, and magnitude of GABAergic mPSC developmental- and ethanol-induced changes in the in vivo model so closely mirror chronologically equivalent adaptations in cultured septal neurons, this suggests that such parallel models of ethanol impairment of GABAergic synaptic development in vivo and in vitro should be useful for translational studies exploring the efficacy and mechanism of action of potential therapeutic interventions from the cellular to whole animal level.

Abstract
The toxic effects of morphine sulfate in the adult cerebral cortex and one-day neonatal cerebellum have been studied. This study was carried out to evaluate the effect of maternal morphine exposure during gestational and lactation period on the Purkinje cells and cerebellar cortical layer in 18- and 32-day-old mice offspring. Thirty female mice were randomly allocated into cases and controls. In cases, animals received morphine sulfate (10 mg/kg/body weight intraperitoneally) during the 7 days before mating, gestational day (GD 0-21) 18 or 32. The controls received an equivalent volume of saline. The cerebellum of six infants for each group was removed and each was stained with cresyl violet. Quantitative computer-assisted morphometric study was done on cerebellar cortex. The linear Purkinje cell density in both experimental groups (postnatal day [P]18, 23.40±0.5; P32, 23.45±1.4) were significantly reduced in comparison with the control groups (P18, 28.70±0.9; P32, 28.95±0.4) (P<0.05). Purkinje cell area, perimeter and diameter at apex and depth of simple lobules in the experimental groups were significantly reduced compared to the controls (P<0.05). The thickness of the Purkinje layer of the cerebellar cortex was significantly reduced in morphine treated groups (P<0.05). This study reveals that morphine administration before pregnancy, during pregnancy and during the lactation period causes Purkinje cells loss and Purkinje cell size reduction in 18- and 32-day-old infant mice.

Abstract
Ethanol exposure during perinatal development can cause cognitive abnormalities including difficulties in learning, attention, and memory, as well as heightened impulsivity. The purpose of this study was to assess performance in spatial learning and impulsive choice tasks in rats subjected to an intragastric intubation model of binge ethanol exposure during human third trimester-equivalent brain development. Male and female Sprague-Dawley rat pups were intubated with ethanol (5.25 g/kg/day) on postnatal days 4-9. At adolescence (between postnatal days 35-38), these rats and sham intubated within-litter controls were trained in both spatial and cued versions of the Morris water maze. A subset of the male rats was subsequently tested on a delay-discounting task to assess impulsive choice. Ethanol-exposed rats were spatially impaired relative to controls, but performed comparably to controls on the cued version of the water maze. Ethanol-exposed rats also showed greater preference for large delayed rewards on the delay discounting task, but no evidence for altered reward sensitivity or perseverative behavior. These data demonstrate that early postnatal intermittent binge-like ethanol exposure has prolonged, detrimental, but selective effects on cognition, suggesting that even relatively brief ethanol exposure late in human pregnancy can be deleterious for cognitive function.

Abstract
The effects of alcohol consumption in adults are well described in the literature, while knowledge about the effects of alcohol consumption in children is more limited and less systematic. The present review shows how alcohol consumption may negatively influence the neurobiological and neurobehavioral development of humans. Three different periods of life have been considered: the prenatal term, childhood, and adolescence. For each period, evidence of the short-term and long-term effects of alcohol consumption, including neurodevelopmental effects and associations with subsequent alcohol abuse or dependence, is presented.

Abstract
During particular periods of central nervous system (CNS) development, exposure to ethanol can decrease regional brain growth and can result in selective loss of neurons. Unfortunately, there are few effective means of attenuating damage in the immature brain. In this study, the possible antioxidant and neuroprotective properties of 17β-estradiol against ethanol-induced neurotoxicity was investigated. 17β-estradiol (600 μg/kg) was injected subcutaneously in postnatal day (PD) 4 and 5, 30 min prior to intraperitoneal injection of ethanol (6g/kg) in rat pups. Ninety minutes after injection of ethanol, the activities of several antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (Gpx) in vermis of cerebellum were assayed. Thiobarbituric acid reactive substance (TBARS) levels were also measured as a marker of lipid peroxidation. Behavioral studies, including rotarod and locomotor activity tests were performed in PD 21-23 and histological study was performed after completion of behavioral measurements in postnatal day 23. The results of the present work demonstrated that ethanol could induce lipid peroxidation, increase TBARS levels and decrease glutathione peroxidase levels in pup cerebellum. We also observed that ethanol impaired performance on the rotarod and locomotor activities of rat pups. However, treatment with 17β-estradiol significantly attenuated motoric impairment, the lipid peroxidation process and restored the levels of antioxidants. Histological analysis also indicated that ethanol could decrease vermis Purkinje cell count and 17β-estradiol prevented this toxic effect. These results suggest that ethanol may induce lipid peroxidation in the rat pups cerebellum while treatment with 17β-estradiol improves motor deficits by protecting the cerebellum against ethanol toxicity.
