Lithium (Li) therapy has widely used in the treatment of bipolar disorder. Consequently, consciousness of the side effects and pathogenesis of this metal is needed for such treatments. Recently, information on the interaction of Li with oxidative markers and organs toxicity attend the researchers over the world. In the present study we have tried to evaluate the influence of oral administration of LiCl for 4 weeks on the oxidative stress marker and histological structure of brain in male rats. Fifty adult male albino rats weighing 135±15 gm was categorized into 5 groups (10 rats each). Group I worked as negative control, group II administrated with LiCl (0.20 mg/kg bw) in drinking water, group III, IV and V were administrated with Zn (10 mg/kg bw), VE (100 mg/kg bw) and their combination twice a week besides the daily administration of LiCl for 4 weeks, respectively. Rats after anesthesia with ether killed for collocation of brain for histopathological and biochemical analysis. Data obtained showed a significant increase in LPO, NO, GSH and Li content and the activities of SOD, CAT and AChE with demylination of the nerve fibers and degeneration of neurons in brain of LiCl treated rats. Co-treatment of ratswith Zn or VE results in a significant decrease in LPO, NO, GSH content in the activities of SOD, CAT and AChE with less or normal structure of the brain. However, co-treatment with combination of Zn and VE caused a significant increase in SOD, CAT and AChE activities with normal histological structure.In conclusion, the data from the present study show that Zn and VE and their interaction are effective in protection against Liinduced brain toxicity in rat with priority for the combination.

The present study aims to evaluate the role of TQ on the oxidative damage induced by ACR in rat testes. The administration of ACR resulted in elevation in testes MDA and NO levels and significant reduction in the level of GSH and the activity of SOD and CAT. Also, plasma testosterone was significantly elevated in ACR-treated rats as compared with negative control. These biochemical changes were associated with congestion and interstitial edema,necrosis, calcification and degeneration of spermatogenic cells and formation of spermatid gaint cells. Co-treatment with TQ ameliorates these biochemical and histological changes. In conclusion, supplementation with TQ as antioxidant may offer protection against ACR induced testicular toxicity.

The general public is exposed to acrylamide from industrial manufacturing, laboratory work, foods rich in carbohydrates that have been cooked at hightemperature,and through cigarette smoke. The present experiment was conducted to investigate the reproductive toxicity of acrylamide exposure in male rats and the role of L-cysteine supplementation in amelioration of this toxicity.

A regular perturbation analysis is presented for the following laminar natural convection flows of Newtonian fluids

Propionic acid modified bagasse was used for the removal of reactive yellow 2 and reactive blue 4. The effects of pH, contact time, initial dye concentrations, adsorbent particle size and adsorbent dose on the adsorption of the two dyes were investigated. Additionally, the desorption process and intra-particle diffusion were studied. Acidic pH values were favorable for adsorption of both dyes. The equilibrium adsorption data were best fitted with the Freundlich isotherm for reactive yellow 2 and the Langmiur isotherm for reactive blue 4. The values of their corresponding constants were de-termined. The kinetic for dye adsorption is well described by a pseudo-first order kinetic model for the reactive yellow 2 and by pseudo-second order for the reactive blue 4. The investigation revealed that the hydroxyl groups of bagasse and the carboxylic group of propionic acid play a great role in the removal of both reactive dyes.
