Twenty eight adult male rats were randomly assigned equally into 4 groups; control group was given distilled water. Lead treated rats were administrated a dose of 44 mg of lead acetate/kg BW. Moringa group was treated with 50 mg/ kg BW of Moringa oleifera leaf extract. Lead and moringa treated group was given a dose of 44 mg/kg of lead acetate and 50 mg/ kg of moringa extract. Treatments were given orally by gavage tube for one month. By the termination of the experimental period, rats were immolated; spleen and thymus weights were recorded in addition to the collection of blood and tissue samples. Tumor necrosis factor alpha (TNF-α), interferon gamma (IF-γ), interlukin-2 (IL-2) and total antioxidant capacity (TAC) were assayed in serum. Complete blood picture was evaluated for rats. Body weight gain was reduced significantly (P<0.05) in lead and moringa treated rats in comparison to control. A significant (P<0.05) increase in spleen weights was observed in lead and moringa co-administered group compared to moringa treated group. Lead administration produced higher (P<0.001) levels of TNF-α, IL-2 and IF-γ compared to that in other groups. In contrary, the level of TAC was significantly (P<0.001) reduced in lead treated rats. A significant (P<0.01) reduction in RBCs and low level of hemoglobin (P=0.07) were observed in lead-treated rats. Spleen of rats receiving lead showed widespread hyperplasia of lymphoid follicles in white pulp and hemosiderin pigment in red pulp. Thymus of rats receiving lead showed marked proliferation in the cortical region. Spleen and thymus of rats receiving lead showed a higher (P<0.01) immune reactivity for NF-κB and CD8+ parallel to that in other groups. In conclusion, the administration of Moringa oleifera extract ameliorates the immunotoxicity induced by lead exposure in rats.","PeriodicalId":11401,"journal":{"name":"Egyptian Academic Journal of Biological Sciences, F.

In addition, the repellent activity of tested extracts against C. pipiens starved females was determined. Results showed that all tested extracts possess larvicidal activity against C. pipiens third larval instar; however, the petroleum ether extract from leaves of P. domestica and R. cathartica was more effective (LC50 33.3 and 63.4ppm) than chloroform (LC50 70.8 and 192.1ppm) and methanolic extracts (LC50 132.7 and 273.5ppm), respectively. Also, both larval and pupal periods were prolonged by all tested extracts as compared with control groups. On the other hand, all tested extracts exhibited a variable degree of repellency against C. pipiens starved females depending on dose and solvent used in extraction. The highest repellency (97.3 and 90.2%) was recorded by petroleum ether extract of P. domestica at the highest doses (3.33 and 5.0mg/cm2), while petroleum ether extract of R. cathartica recorded 89.8 and 80.0% repellency at the same doses, respectively. These results proved that methanol, chloroform and petroleum ether extracts of P. domestica and R. cathartica leaves act as C. pipiens control agents, even in the crude form, providing an opportunity to reach ,mosquito control agents from cheap, available plants which are safe to non-target organisms, as well as environment.","PeriodicalId":11401,"journal":{"name":"Egyptian Academic Journal of Biological Sciences, F.

Almond moth (Ephestia cautella) is a destructive insect of stored products, such as dates, wheat flour, and nuts. In the present study, the usage of novel groups of insecticides (Spinosyns, Diamide, Pyridalyl, and Azadirachtin) that are safe for humans and exert a relatively lower effect on the environment was assessed. In particular, the toxicological and biochemical impacts of five insecticides (Tracer, Radiant, Coragen, Pleo, and Achook) on the control of E. Cautella were evaluated, and the genome-wide DNA mutability caused by these insecticides was screened. A bioassay was performed in order to determine the LC50value for each insecticide, the results of which revealed that Coragen with an LC50 value of 0.49 ppm was the most potent insecticide, followed by Radiant and Achook (with LC50 values of 1.51 and 1.73 ppm, respectively). In addition, the effect of these insecticides on vital enzymes was investigated. The data from this investigation revealed that the treatment with Radiant demonstrated stimulation in AST, ACP, ALP, and GST activity, and inhibition in AChE, ALT, and protease activity. The insects treated with Coragen exhibited an elevation in the activities of AChE, GST, ALP, ACP, ALT, and protease. Finally, DNA-level mutability caused by the insecticides was assessed by using RAPD-PCR analysis, and the results indicated Radiant as a genotoxic insecticide that caused large changes at the genomic-DNA level. On the other hand, Coragen exhibited the lowest mutability effect on insect DNA.","PeriodicalId":11401,"journal":{"name":"Egyptian Academic Journal of Biological Sciences, F.

Therefore, the developing embryos in the society are more vulnerable than adults to the chronic cholinergic intoxication. This study aimed to examine the chronic effect of pesticides mixture on the AChE of developmental embryo in an avian model, which does not share the maternal potential confounds. For this, fresh fertile chicken eggs (Gallus gallus domesticus) were used. The lethal concentration of pesticides mixture for 50% killing (LD50) values was computed on the basis of probit analysis and was found to be 40 ppm. 1/5 th LD50 and 1/10 th LD50 (8 and 4 ppm) were chosen to be the tested doses. Eggs weighing 54±1 gm were separated in to 3 batches of 10 eggs each batch. One batch of embryos was injected with normal saline and the other batches of embryos injected with pesticides mixture of 4 and 8 ppm each alternative day starting from incubation day 7 for 2 weeks. On day 21 after 12 hours of the last dose an amount of 200 µl blood was collected from the blood vessels surrounding the embryonic membranes and the heamolyzate was used for the assessment of the AChE activity calorimetrically. Result of this study indicated that 1/10 th of the LD50 had only marginal effect on the AChE activity (40.6%). Whereas 1/5 th of the LD50 of pesticides mixture caused significant inhibition of AChE activity (69%) which could not be reversible. So neuro-developmental consequences such as behavioral changes and memory impairment may prolong throughout the life span of the embryo.","PeriodicalId":11401,"journal":{"name":"Egyptian Academic Journal of Biological Sciences, F.
