Background: Mercuric chloride (HgCl 2 ) is toxic to humans and animals, and usually causes systemic and nerve damage. Aim: The aim of this study is to evaluate the neuro-protective effects of two medicinal plants rich in antioxidants against mercuric chloride poisoning in Wistar rats. Materials and Methods: This is an experimental study conducted on twenty-five adult rats randomly divided into five groups of five rats each, the untreated control group and the four groups are treated daily with Ginger extract (500 mg/kg/day) and Nigella sativa oil (2ml/kg/day) for four weeks. The administration of mercuric chloride (4mg/kg/day) will be from the second week of experimentation to three weeks. Results: The results obtained showed by behavioral tests that the administration of inorganic mercury (HgCl 2 ) significantly increases the state of anxiety and depression of rats compared to control rats, while the groups pre-treated with antioxidants can reduce the damage of these behavioral disorders. Conclusion: Ginger extract and Nigella sativa oil have a very important role in neurobehavioral alterations induced by mercury toxicity.

The aim of this study was carried out to investigate the possible hepato protective effect of Zinc and Magnesium against subchronic cadmium toxicity on biochemical, histopathological and neurobehavioral parameters in Wistar rats during 90 days. Fourty Wistar rats, were randomly divided in four experimental group: 1, control only water; 2, water and oral administration (Cd); 3, (Cd+Mg) in water oral administration; 4, (Cd+Zn) in water oral administration. Zinc and Magnesium was used to reduce hepatoxicity and neurobehavioral disorders induced by Cadmium in Wistar rats. The Cd-Zn and Cd-Mg groups received 10 mg/kg of ZnCl2, 10 mg/kg of MgCl2 added to drinking water. The Cd group received 15mg / kg of CdCl2. Blood glucose level and body weight were measured every day. According to the results, which have been obtained. There was a reduction in body weight gain due to Cd group and an increase liver weight. The results indicated also changes in biochemical parameters, which are characterized by an increase in serum glucose, serum urea, serum creatinine, of animals contaminated with cadmium compared to the control animals. However, the supplementation of (Zn) and Mg combination improved some but not all the previous parameters. Moreover, the findings showed variation in hematological parameters of Cd treated animals. In other word, there was a rise in number of white cells, and reduction of red cells counts, hemoglobin concentration and hematocrit percentage, but all these parameters returned approximately to their normal values after combined Zn and Mg addition. The neurobehavioral test shows an increase in the number of cells crossed, the number of straightening in the test. Open field in the group exposed to Cd resulting in locomotors hyperactivity compared to the control and it is minimal in other groups treated with Zn and Mg. On the other hand, the elevated plus maze (EPM) revealed an increase of the time spent in the closed arms of the cadmium group compared to the control. The results clearly showed also deteriorations of liver structure tissue in comparison with the controls, including extensive degeneration of hepatocytes with necrosis, inflammation, the presence of cellular debris within a central vein and cytological vacuolization. The present investigation indicated that Cd had toxicity effects on the previous mentioned parameters. However, the supplementation of combined Zn and Mg was ameliorated some of these parameters and reduced liver histological alterations caused by Cd toxicity.

This study aims to evaluate the effect of fenugreek on biochemical parameters, body weight, and the behavior of male Wistar rats. The purpose of administering the aqueous extract of fenugreek seeds (Trigonella foenum-graecum L) for 30 successive days by oral gavage (force-feeding) at a dose of 250g / l of water is intended to assess, on the one hand, the neurobehavioural effects and 'on the other hand its effect on some biochemical parameters (glycemia and lipid balance) as well as weight. The behavioral tests performed are the Light/Dark Box tests (LDB) and the Elevated Plus Maze test (EPM). This work indicated that the consumption of the aqueous extract of the seeds of fenugreek is beneficial to stimulate appetite and gain weight, thus decreasing the level of total cholesterol, triglycerides, LDL-C, and a significant increase in HDL-C, also a reduction in blood sugar and a decrease in anxiety.

Environmental pollution is the unfavorable alteration of our environment, wholly or mainly as a by-product of human actions, by the direct or indirect effects of changes in energy patterns, radiation levels, the chemical and physical constitution, and the abundance of the organisms. Thus, the environment's pollution is one of the most severe problems humanity and other forms of life face today on our planet, and this population makes severe disruption. The xenobiotic substances responsible for this pollution are numerous and diverse due to multiple human activities that can be the source. However, attention mainly focuses on fertilizers, pesticides, heavy metals, and certain petrochemicals of significant consumption, such as solvents. The purpose of this study is to highlight the reprotoxic and hepatotoxic effects of Ethylene Glycol Monoethyl Ether (EGME) on male Wistar rats. Male Wistar rats were exposed to Ethylene Glycol Monomethyl Ether alone (EGME) (500 mg/kg), combined with the aqueous extract of the pollen grains of Sinapis arvensis (P-EGME) (300 mg/kg), in addition to the control (T) and positive control (P) groups for a period of 4 weeks by gavage, to estimate the protective role of this plant against the intoxication of EGME. The results show that EGME can induce reprotoxic effects revealed by a reduction in testes and epididymis mass accompanied by decreased male fertility indicators (sperm concentration). The results also show that treatment with EGME caused a reduction in the red blood cell number, hemoglobin and hematocrit rate, white blood cells in the treated groups compared to the control groups. The present study revealed that treatment with Ethylene Glycol Monoethyl Ether (EGME) under the same experimental conditions could affect several biological markers, especially male fertility. Besides, the protective activity of the wild mustard (Sinapis arvensis) pollen in the face of cellular oxidative damage induced by EGME. So, it is suggested that this pollen could be used as a cell protector.
