Analytical Chemistry - Abstract
Pyridine derivatives are the most common and significant heterocyclic compounds, which play an important role in various fields ranging from medicinal to chemosensing applications. Pyridine derivatives possess different biological activities such as antifungal, antibacterial, antioxidant, antiglycation, analgesic, antiparkinsonian, anticonvulsant, anti-inflammatory, ulcerogenic, antiviral, and anticancer activity. Furthermore, these derivatives have a high affinity for various ions and neutral species and can be used as a highly effective chemosensor for the determination of different species. In this review article, generally used synthetic routes of pyridine, structural characterization, medicinal applications, and potential of pyridine derivatives in analytical chemistry as chemosensors have been discussed. We hope this study will support the new thoughts to design biological active compounds and highly selective and effective chemosensors for the detection of various species (anions, cations, and neutral species) in various samples (environmental, agricultural, and biological).

The Severe Acute Respiratory Syndrome-related Coronavirus 2 (COVID-19 or SARS-CoV-2) epidemic is professed as world disaster producing a worrying increasing mortality, particularly amongst vulnerable humans worldwide. Whether COVID-19 has a strong ability for acceptable genetic flexibility that amended for breaking immune responses quickly, it is critical to understand the adaptation mechanism between viruses and hosts that allows individuals to follow viral development. This can contribute to finding the appropriate treatment to combat the epidemic. However, the present information about viral adaptation mechanisms in hosts is still insufficient, and future investigations may reveal the unknown. Mutations and genetic variations are naturally occurring; however, the current knowledge about their mechanism and pathways still has many secrets. The present review also provides insights into the immune system, immunological memory, and the development of the COVID-19 vaccine. Other fighting methods against COVID-19 are also highlighted. The potential of antibodies, natural metabolites, and current suggest vaccines were applied to the face of this new threat.

Natural clinoptilolite was decorated by green MgO nanoparticles (G. MgO/Clino) and characterized as a potential drug delivery system for 5-Fluorouracil drug. The synthetic G. MgO/Clino as carrier exhibits an enhanced loading capacity of 244.5 mg/g which is higher than clinoptilolite (163 mg/g). The loading reaction of 5-FC follows the equilibrium and kinetic properties of Langmuir and Pseudo-first order models, respectively. Therefore, the loaded 5-FC molecules are of homogenous and monolayer forms with Gaussian energy (8.51 kJ/mol) related to physisorption and zeolitic ion exchange processes. Also, the thermodynamic study declared feasible, endothermic, and spontaneous loading reactions of the 5-FC drug. The release study emphasizes a long and continuous profile for 150 h either in gastric buffer (pH 1.2) or intestinal buffer (pH 7.4). The release kinetics follow Higuchi and Hixson-Crowell model in addition to Korsmeyer–Peppas model with diffusion exponent (0.50 at pH 1.2 and 0.47 at pH 7.4). This suggests non-Fickian transport behavior for the released 5-FC molecules by both erosion and diffusion mechanism. The cytotoxicity study on the colorectal normal cell (CCD-18Co) demonstrates significant safety and biocompatibility properties of G. MgO/Clino as a drug carrier. Moreover, the G. MgO/Clino carrier induced the cytotoxic effect on the colon cancer cells (HCT-116) by controlling the diffusion rate and the oxidative effect of the green MgO nanoparticles.

Graphical abstract Alleviation of silver nanoparticle-induced sexual behavior and testicular parameters dysfunction in male mice by yttrium oxide nanoparticles. Gasem Mohammad Abu-Taweel, Hani Manssor Albetran, Mohsen Ghaleb Al-Mutary, Mohammad Ahmad, It Meng Low., Highlights • Exposure to silver nanoparticles decreased the weight of the reproductive organs, sexual behavior, oxidative defense parameters, sperm count and their motility in male mice. • In addition, serum testosterone, apoptotic germ cells and testicular histology were also disrupted due to silver nanoparticles. • Yttrium oxide nanoparticles have protective effects on sexual behavior and spermatotoxicity induced by silver nanoparticles in male mice. • The toxicity of silver nanoparticles altered testicular functions that were effectively ameliorated by yttrium oxide nanoparticles., Silver nanoparticles (Ag-NPs) can easily cross through the blood-testis barrier and encourage reproductive dysfunction. This study investigated the protective effects of yttrium oxide nanoparticles (YO-NPs) on sexual behavior and spermatotoxicity induced by Ag-NPs in male mice. Twenty-four male mice were separated into four groups and injected intraperitoneally once a week as the following: group I (Ag-NPs at the dose of 40 mg/kg), group II (YO-NPs at the dose of 40 mg/kg), group III (Ag + YO NPs at the doses of 40 mg/kg, each) and group IV (control; distilled water). After 35 days of the injections, the sexual behavior, oxidative parameters in testis, sperm parameters, serum testosterone, apoptotic germ cells and testicular histology were evaluated. Our findings showed that Ag-NPs decreased the weight of the reproductive organs, sexual behavior, oxidative defense parameters, sperm count and motility of male mice. In addition, the apoptotic cells in testicular cross-sections and TBARS level increased after Ag-NPs exposure when compared to other groups. However, the YO-NPs had protective effects in the studied parameters of testicles and minimized the Ag-NPs toxicity in male mice. In conclusion, the results revealed that the toxicity of Ag-NPS altered testicular functions in male mice that were effectively ameliorated by YO-NPs.

The main objective of this work is to analyze the perinatal protective effects of curcumin (Cur) on the toxicity of inorganic mercury (mercuric chloride – HgCl2) in the developing mice offspring on their behavioral and biochemical changes. Six groups of pregnant mice (consisting of ten animals in each) were allocated in a way that Group I consuming tap water was used as control. Groups II to VI were the experimentally treated groups in which Group II and III received 150 and 300 ppm of curcumin, respectively; Group IV was given 10 ppm of HgCl2; and Group V and VI were also exposed to 10 ppm of HgCl2 but concurrently they were also treated with 150 and 300 ppm of curcumin, respectively. Appearance of vaginal plug was considered as the first day of pregnancy and all treatment started from day one of pregnancy until post-natal day 15 (PD 15) and the mothers were switched to plain tap water thereafter. At the age of PD 40, the male pups were subjected to measuring the depression in the light-dark chambers, forced swimming and tail suspension tests and to measuring their anxiety in plus-maze and open-field tests. Subsequently, after behavioral tests, the levels of corticosterone and cortisol hormones were estimated in the plasma of the experimental offspring. Behavioral tests were measured in the HgCl2 treated offspring for the light-dark chambers; forced swimming test; tail suspension test; plus-maze test; and open –field test showed significant alterations in their depression, anxiety and locomotory activities. Biochemical estimation of corticosterone and cortisol hormones in the plasma of these offspring showed significant depletion in their levels. Treatment of these offspring with curcumin significantly and dose dependently ameliorated all the behavioral and biochemical disruptive effects in the offspring due to HgCl2 toxicity. In conclusion, curcumin ameliorates the toxic effects of HgCl2 in the offspring during gestation and lactation periods. Thus, exposure to HgCl2 to mothers during pregnancy needs careful monitoring for minimizing its toxicity. Curcumin appears to be a promising ameliorating agent for such HgCl2 toxicity; however, further studies are needed for establishing these preliminary findings.

Coastal vulnerability assessment is the key to coastal management and sustainable development. Sea level rise (SLR) and anthropogenic activities have triggered more extreme climatic events and made the coastal region vulnerable in recent decades. Many parts of the world also noticed increased sediment deposition, tidal effects, and changes in the shoreline. Farasan Island, located in the south-eastern part of Saudi Arabia, experienced changes in sediment deposition from the Red Sea in recent years. This study used Digital Shoreline Analysis System (DSAS) to delineate the shoreline changes of Farasan Island during 1975–2020. Multi-temporal Landsat data and DSAS were used for shoreline calculation based on endpoint rate (EPR) and linear regression. Results revealed an increase in vegetation area on the island by 17.18 km2 during 1975–1989 and then a decrease by 69.85 km2 during 1990–2020. The built-up land increased by 5.69 km2 over the study period to accommodate the population growth. The annual temperature showed an increase at a rate of 0.196 °C/year. The sea-level rise caused a shift in the island's shoreline and caused a reduction of land by 80.86 km2 during 1975–2020. The highly influenced areas by the environmental changes were the north, central, northwest, southwest, and northeast parts of the island. Urban expansion and sea-level rise gradually influence the island ecosystem, which needs proper attention, management, policies, and awareness planning to protect the environment of Farasan Island. Also, the study’s findings could help develop new strategies and plan climate change adaptation.

This experiment aimed to determine how pomegranate juice (PJ) responds to oxidative stress induced by aluminum in male mice. A total of thirty-six male mice were separated into six groups. The first group (control group) received tap water. Groups two and three were given 20% and 40% PJ, respectively. Group four received 400 mg Al/kg, while groups five and six were given Al + 20% PJ and Al + 40% PJ, respectively. After the oral administration period, the sexual behavior of the mice was recorded. Blood was collected from the heart to measure testosterone concentration. After the animals were sacrificed, the reproductive organs were weighed, and the epididymis and testis were used for further evaluations. Our findings showed that Al decreased the body and organs weights, sexual behavior, sperm count, normal sperm, total and progressive sperm motility, testosterone level, and epithelial diameters of the seminiferous tubes. In addition, the PJ reduced these effects and minimized the aluminum toxicity in male mice. In conclusion, PJ protects against aluminum exposure in male mice by ameliorating sexual behavior and fertility.

General Physics and Astronomy - Abstract
In recent years, antibiotics have been considered emerging pollutants due to their continuous input and their persistence in the aquatic ecosystem, even at low concentrations. The present work focuses on the successful hydrothermal synthesis and characterization of CeO2 nanoparticles for the electrochemical detection of nitrofurantoin (NFT) antibiotic. Their physicochemical properties were studied by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and UV-Vis spectroscopy. The average particle size and the energy bandgap of CeO2 nanoparticles were found to be 9.59 nm and 3.3 eV, respectively. Furthermore, electrochemical analysis showed that the developed CeO2 -based electrode showed improved electrocatalytic activity towards the oxidation of nitrofurantoin (NFT) compared to the bare electrode. The limit of detection (LOD) was obtained as 7.81 μM from the calibration curve. Hence, these results corroborate that the CeO2 nanoparticles modified electrode can serve as a novel NFT electrocatalyst.

Purpose Aluminum (Al) is a harmful metal to organisms and is capable of entering the human body in multiple ways, such as through drinking, breathing, deodorant use, and vaccination. This study examined the prospective toxicity of Al and the protective attributes of pomegranate juice (PJ) on neurobehavioral and biochemical parameters of male mice. Methods Six groups of male mice were treated for 35 days with 20 % PJ (group II), 40 % PJ (group III), 400 mg/kg Al (group IV), Al + 20 % PJ (group V), Al + 40 % PJ (group VI) or tap water (control, group I). Behavioral assessments were conducted for learning and memory evaluations at the end of experiment. In addition, the forebrain was isolated for biochemical analysis. Results The exposure of male mice to Al decreased learning and memory retention in the shuttle box, Morris water-maze and T-Maze tests. Biochemical analysis revealed significant depletions in neurotransmitters including DA, 5-HT and AChE and oxidative proteins including GSH, GST, CAT and SOD and increased TBARES levels in Al-treated mice compared to untreated mice. Pomegranate juice provided protection against these effects after Al exposure by ameliorating learning and memory retention and oxidative state in a dose-independent manner. Conclusion Our data demonstrated that Al exposure caused behavioral and biochemical disorders. Pomegranate juice in lower dose has beneficial properties for health and can be used as a source of antioxidants to reduce the toxicity of Al and other substances.

Purpose Aluminum trichloride (AlCl3) exposure was proven to encourage some behavioral deficits and eventually induces anxiety and depression in rodents animals. Therefore, this experiment aimed to scout about the effects of pomegranate juice on anxiety- and depression-like behaviors caused by AlCl3 in male mice. Methods Six groups of male mice were administrated orally for 35 days by PJ and AlCl3. The control group (G-I) received tap water, while the PJ groups (G-II and G-III) were treated with 20 % and 40 % PJ, respectively. The AlCl3 group (G-IV) was treated with 400 mg/kg/day of AlCl3, and the last two groups (G-V and G-VI) were treated with AlCl3 and 20 % PJ or 40 % PJ, respectively. Then, the open-field (O-F), elevated plus maze (EPM), tail suspension (TS), forced swimming (FS), and light/dark box (L/DB) tests were applied for anxiety- and depression-like behavior studies. In addition, neurotransmitters and oxidative parameters in the brain were evaluated. The plasma cortisol was measured at the end of the experiment. Results Behavioral analyses showed that PJ inhibited AlCl3-induced depressive and anxiogenic effects in the O-F, EPM, TS, FS, L/DB tests. In addition, neurochemical results indicated that PJ at 20 % concentration minimized the AlCl3 toxicity on dopamine (DOP), serotonin (SER), and acetylcholinesterase (AChE) levels in the for-brain of male mice. Moreover, PJ moderated the AlCl3 effects by decreasing the level of thiobarbituric acid reactive substances (TBARS), and enhancing catalase (CAT), superoxide dismutase (SOD), glutathione S-transferase (GST) and glutathione (GSH) activities. The plasma cortisol increased in male mice treated with AlCl3 and in a group treated with a high dose of PJ. Conclusion Our results proposed that the anxiety- and depression-like behaviors induced by AlCl3 exposure in male mice can be ameliorated by PJ treatment, probably through the inhibition of oxidative damage and minimizing the changes in neurotransmitters and hormonal activity.

Hybrid structure from mesoporous silica (MCM-48) and β-cyclodextrin polymer (β-CD/MCM) was prepared for enhanced remediation of As (V) and Hg (II) ions. The β-CD/MCM showed promising uptake affinities for As (V) and Hg (II) ions even in the existence of coexisting anions or metal ions. The maximum capacities are 265.6 mg/g and 207.9 mg/g for the As (V) and Hg (II) ions, respectively. The data followed Pseudo-First order kinetic behavior and Langmuir equilibrium properties declaring homogenous and monolayer adsorption. The values of Gaussian energy (6.45 KJ/mol for As (V) and 3.95 KJ/mol for Hg (II) ions) emphasize the physical nature of their uptake by β-CD/MCM. The thermodynamic studies reflected their adsorption by spontaneous, favorable, and exothermic reactions. Using the β-CD/MCM as a fixed bed in column system achieved total removal percentages of 72.8 % (As (V)) and 60.4 % (Hg (II)) in addition to total adsorbed metals of 879.8 mg (As (V)) and 717.2 mg (Hg (II)) for 8.1 L of polluted water. Therefore, the synthetic β-CD/MCM composite is of promising adsorption properties to be applied in the decontamination of As (V) and Hg (II) ions either in batch studies or fixed bed column studies.

Background: Cardamom is the flavouring spices mainly cultivated all over the world. Apart from being used as the spice, it has many medicinal values. Therefore, the present study aimed to investigate the potential use of cardamom and its effects on the ability of learning, developmental, and various biochemical factors of Swiss-Webster mice offspring at different stages. Methods: In this method, Swiss-Webster mice offspring at different stages were used for the analysis of biochemical factors. After the administration of cardamom orally, the pups were subjected to various tests for determining social and defense behaviors of males and females, anxiety behavior; locomotor and neuromuscular activities, haemotological parameters, and hormonal factors of males and females. Results: The present findings indicate that the cardamom induced reduction in the social and defense behaviors of males and females, respectively, and also anxiety behavior. Interestingly, locomotor and neuromuscular activities decreased significantly. Discussion: In addition, the packed cell volume, red blood count, hemoglobin content, AChE in forebrain, the testosterone in males and progesterone in females were observed to increase significantly, whereas the blood platelets and total white blood count decreased non-significantly. Through perinatal exposure, cardamom can pass through the placenta or/and lactation and reaches the fetus. Care must be taken when using cardamom and especially during pregnancy and lactation. Conclusion: The administration of cardamom enhances the ability of social, developmental, and various biochemical factors of Swiss-Webster mice offspring at different stages.

The present study aimed to investigate the individual and combined effect of mono-sodium glutamate (MSG) and aspartame (ASM) on biochemical, blood parameters and neuro-behavioral aspects of mice. The results indicated that exposure induced many changes in fear and anxiety behavior. The non-social and social behavior of the exposed mice was significantly affected, showing an increase in the former and a decrease in the later stages, respectively. The elements of social behavior including attack, numbers of fights and bites, naso-nasal and naso-genital contacts were decreased significantly. The latencies to threat and attack and first bite were increased significantly. Locomotor activity and neuromuscular coordination (grip strength) were decreased in treated animals as compared to the control group. There was a significant decrease in the red blood cell count, packed cell volume, hemoglobin concentration, white blood cell count platelets count and testosterone hormone in the treated males. The activity of acetylcholinesterase enzyme decreased as compared to the control. In conclusion, the current study indicated that exposure to food additives MSA and ASM was dangerous to mice in relation to behavior and biochemical analysis. In addition, these food additives need more scientific researches to investigate their effect on other parameters. Key words: Mono-sodium glutamate, mono-sodium aspartame, fear and anxiety, locomotory behavior, grip strength, acetylcholinesterase.

Cadmium (Cd) exposure can induce acute lethal health-related threats in humans since it has an exceptional ability to accumulate in living organism tissues and cause toxicological effects. Curcumin (Cur) on the other hand has a wide variety of biological activities and several studies have suggested its potential therapeutic or protective effects against several ailments and infections. To study the effect of Cur on the toxicity of Cd, Swiss–Webster strain male and female mice (sixty each) were divided into 6 groups of ten each at random. Group-1 served as the naive control and received no treatment. Group-2, 3 and 4 were the experimental controls and were administered once a day with a single oral dose of 50% dimethyl sulfoxide (DMSO), Cur (300 mg/kg) or Cd (100 mg/kg) respectively, for 2 weeks. Group-5 and 6 received Cur and Cd in combination once a day orally for 2 weeks except that Cur in a dose of 150 and 300 mg/kg to group 5 and 6 respectively, was administered one hour before Cd administration to both groups. After treatment period, the male animals were subjected to social standard opponent test and females were subjected to the tube restraint tests and thereafter, their blood was collected to measure the blood composition indices and level of reproductive hormones. The animals were sacrificed to collect their brain for the estimation of acetylcholinesterase (AChE). Results indicated that Cd significantly increased nonsocial activities in males and latency to first bite in females, whereas the social activities in males and the number of bites in females were significantly decreased. All measured indices of blood composition and levels of progesterone (female) and testosterone (male) in blood and AChE in their brain tissues were significantly decreased due to Cd treatment. However, administration of Cur along with Cd had an ameliorating effect on all the behavioral and biochemical parameters studied herein and reduced the toxicity of Cd significantly and dose-dependently. Thus, Cur may be beneficial for general health and for protection from Cd intoxication.

Cordyceps militaris is a type of fungus consumed by people all over the world and renowned for their nutritional benefits and herbal formulas to promote health and longevity. In the present study investigation was carried out to explore the therapeutic properties and neuroprotective effect of the C. militaris on ischemic brain neuronal injury, impairment of memory and learning in experimental rats induced by a global cerebral ischemia-reperfusion injury in WISTAR rats. Vascular Dementia with transient global brain injuries induced by a four-vessel occlusion (4-VO) in WISTAR rats. Further, donepezil (5 mg/kg) and C. militaris was (100 and 300 mg/kg, p.o.) were orally administered for 7 days in 4-VO WISTAR rats. C. militaris has the ability to improve memory impairments due to global cerebral ischemia and scopolamine-induced memory deterioration. Our present findings suggest that C. militaris may be a potential candidate for the neuroprotection of hippocampus and the recovery of various vascular dementia or neuroinflammatory disorders. Keywords: Cordyceps militaris, Global cerebral ischemia, learning, Memory

The present study was designed to investigate the in vivo effects of monosodium glutamate (MSG) and aspartame (ASM) individually and in combination on the cognitive behavior and biochemical parameters like neurotransmitters and oxidative stress indices in the brain tissue of mice. Forty male Swiss albino mice were randomly divided into four groups of ten each and were exposed to MSG and ASM through drinking water for one month. Group I was the control and was given normal tap water. Groups II and III received MSG (8 mg/kg) and ASM (32 mg/kg) respectively dissolved in tap water. Group IV received MSG and ASM together in the same doses. After the exposure period, the animals were subjected to cognitive behavioral tests in a shuttle box and a water maze. Thereafter, the animals were sacrificed and the neurotransmitters and oxidative stress indices were estimated in their forebrain tissue. Both MSG and ASM individually as well as in combination had significant disruptive effects on the cognitive responses, memory retention and learning capabilities of the mice in the order (MSG+ASM)>ASM>MSG. Furthermore, while MSG and ASM individually were unable to alter the brain neurotransmitters and the oxidative stress indices, their combination dose (MSG+ASM) decreased significantly the levels of neurotransmitters (dopamine and serotonin) and it also caused oxidative stress by increasing the lipid peroxides measured in the form of thiobarbituric acid-reactive substances (TBARS) and decreasing the level of total glutathione (GSH). Further studies are required to evaluate the synergistic effects of MSG and ASM on the neurotransmitters and oxidative stress indices and their involvement in cognitive dysfunctions.

Cadmium (Cd) exposure can induce acute lethal health-related threats to humans since it has an exceptional ability to accumulate in living organisms and cause toxicological effects. Curcumin (Cur) on the other hand has a wide variety of biological activities and several animal studies have suggested for a potential therapeutic or preventive effects against several ailments and infections. To study the effect of Cur on the toxicity of Cd, sixty Swiss-Webster strain male mice were divided into 6 groups of ten each at random. Group-1 served as the na?ve control and received no treatment. Group-2, 3 and 4 were the experimental controls and were administered once a day with a single oral dose of 50% dimethyl sulphoxide (DMSO), Cur (300 mg/kg) or Cd (100 mg/kg) respectively, for 2 weeks. Group-5 and 6 received Cur and Cd in combination once a day orally for 2 weeks except that Cur in a dose of 150 and 300 mg/kg to group 5 and 6 respectively, was administered one hour before Cd (100 mg/kg) administration to both groups. After treatment period, the animals were subjected to behavioral tests and thereafter, the animals were sacrificed for the estimation of neurotransmitters like serotonin (5-HT), dopamine (DA) and it’s metabolite 3,4-dihydroxyphenylacetic acid (DOPAC) as well as oxidative stress enzymes like lipid peroxides in the form of thiobarbituric acid–reactive substances (TBARS) and total glutathione (GSH) in the forebrain tissue. Cd reduced significantly the body weight gain, the locomotor activity, anxiety behavior in the plus maze and the learning capability (cognitive effect) in the shuttle-box test. Biochemical analysis further revealed that Cd exposure significantly altered the brain neurotransmitters and the oxidative stress enzymes. However, administration of Cur along with Cd had an ameliorating effect on all the behavioral and biochemical parameters studied herein and reduced the toxicity of Cd significantly and dose-dependently. Thus, Cur may be beneficial for anxiety, neuromuscular, and cognitive problems and protect from Cd intoxication.

Lead is one of the common chemical elements that is assigned the symbol Pb which came from the Latin Plumbum. Pb is widely used in the field of coating, refine and glaze ceramics and pottery. It is still used in the production of products like water pipes, cooking utensils and cooking utensils. In addition it is also used in insulation of building ceilings, cable coverage and military industries. Lead enter the environment from those uses and from the environment it enter into the living organisms. Lead accumulates in many humanorgans, but the brain is the target organ of lead accumulation. Neurotoxicity of lead is, one of lead toxicity, caused many symptoms. There are many behavioral and biochemical modifications induced by lead toxicity like learning and memory deficits, anxiety disorders, social and sexual behavior modifications and neurotransmitter system deficits. Curcumin is a bioactive natural phytochemical phenolic compound (diferuloylmethane) extracted from the rhizome of Curcuma longa. Most studies indicated the role of curcumin in reducing the damage of lead toxicity. In the current review, emphasis was based on the toxicity of lead and its effect on behavior and some neurotransmitters related to behavior. The effect of curcumin is improving the neurotoxicity and behavioral toxicity of lead.

Aluminum (Al) is a known neurotoxicant and circumstantial evidence has linked this metal with several neurodegenerative disorders like Alzheimer's disease, but no causal relationship has yet been proved. Al-induced behavioral alterations as well as cognitive deficits and rodent brain neurotransmitter level, are well known in adults but the exact mechanism in the offspring of perinatally Al exposed dams is not yet understood properly and needs more attention. In the present study, the perinatal oral exposure of the dams to 300 and 600 mg/kg/day Al (aluminum chloride) resulted in significant and deleterious effects in the offspring inflicting a dose-dependent reduction in postnatal body weight gain, delays in opening of the eyes and appearance of body hair fuzz, and deficits in the sensory motor reflexes of the mice pups during weaning period (from the day of birth to postnatal day 21). During adolescent ages of the male offspring, a significant and dose-dependent deficit was also observed in their locomotor activity at postnatal day 22 (PD 22), learning capability (at PD 25), and cognitive behavior (at PD 30–36). Furthermore, a significant and dose-dependent disturbance in the levels of neurotransmitters like dopamine (DA) and serotonin (5-HT) was also observed in the forebrain region of the offspring at PD 7, PD 14, PD 21, PD 30, and PD 36. Thus, perinatal Al exposure, particularly during pregnancy and lactation period, can affect the in utero developing fetus and postnatal developing sucklings, raising the concerns that during a critical perinatal period of brain development, Al exposure has potential and long lasting neurotoxic hazards and might modify the properties of the dopaminergic system and thus can change the threshold of that system or other related systems at later ages. A reduced use of Al during pregnancy is of crucial importance in preventing Al-induced delayed neurotoxicity in the offspring.

Selenium is an essential element with a narrow margin between beneficial and toxic effects. The learning and sensory motor reflexes-changes were studied after the perinatal exposure of mice to acute toxic doses of sodium selenite. Atomic absorption as well as the behavioral observations were employed. Adult pregnant mice was assigned into three groups: the first group was remained as a control group; the second and the third groups were orally administrated sodium selenite at doses of 1 mg/Kg (1 ppm) and 4 mg/kg (4 ppm) of the diet, respectively started from the 7th day of gestation to the 15th day of birth. Results revealed that body weight gain came significantly lower in pups born to treated mothers than those of the control pups. The appearance of body hair and opening of eyes of the pups from treated mothers were delayed in a dose-dependent manner. Selenite also inhibited the sensory motor reflexes in all elements in a dose dependent manner. The active avoidance test indicated that selenite exposure was associated with learning impairment. Acetylcholine recorded a significant decrease in treated pups. Significant high concentrations of selenium in the brain, liver and kidney was detected, indicating active transfer of selenium from mothers during pregnancy and lactation periods. Key words: Perinatal, sodium selenite, atomic absorption, acetylcholine, active avoidance test, sensory motor reflexes, mice.
