Vol.1 No.4 -6 : North African sharptooth catfish Clarias gariepinus In silico analyses for genetic expansion of a peculiarly successful catfish species in and out of its African homelands.

By : Khaled Mohammed-Geba Abstract The African sharptooth catfish Clarias gariepinus originated from Africa, but its sturdiness and resistance to different environmental conditions enabled it to spread to almost all continents of the world. To develop effective conservation strategies for C. gariepinus, the connection patterns of its geographically related and isolated strains should be precisely […]

Vol.1 No.4 -7 : Impact of seasonal changes on the quality of water and fish from Abu Za’baal Lakes.

By : Hala Elshahat Ghannam1, Abdelrahman Said Talab2* and Abdel-Samie Abd El-Hamide Elewa3 Abstract Physicochemical characteristics and concentrations of some heavy metals of water and two fish species in Abu Za’baal lakes during the period from summer 2012 to spring 2013 were investigated. The physicochemical characteristics of water and fish were proved to be within […]

Vol.1 No.3 -1 : Ameliorative influence of Ginkgo biloba extract on acetaminophen-induced oxidative stress in livers and kidneys of male albino rats.

By : Mohammed F.F. Bayomy* and Aziza Ali Salah Eldinn** Abstract In this study, the effects of Ginko biloba extract on -treated groups were divided subchronically-induced toxicity of acetaminophen (AAP) on functions of livers and kidneys of male albino rats were investigated. Subchronically into 8 groups. Animals of group1 received tap water daily for 1 […]

Vol.1 No.3 -2 : The possible protective effect of vitamin E and ∕ or silymarin on rat testes exposed to 950MHz electromagnetic field.

By : Amr Mahmoud Abd El-Hady* and Noaman Abd El-Latif. El-Tahawy** Abstract This work aims to study the histopathological and histochemical changes in the testes of male albino rats post exposure to mobile phone radiation and the possible protective role of vitamin E and/or silymarin. The current experiment was carried out on 30 adult male […]

Vol.1 No.3 -3 : A new approach in bacteriological and chemical treatment of surface water for drinking purpose.

By : Hisham.M1; Shaaban M.T.2 ; Sara. A3; Fakhrany.M4 and Hazaa.M.M. Abstract The surface water contain some dissolved contaminants such as iron and manganese. It is unsuitable for drinking water without appropriate treatment. Under standard and steady-state conditions, the bioreactor was very effective when 2% of the nano polymer composite granules (w/v)borne bioagent bacteria as […]

Vol.1 No.3 -5 : Preventive effect of melatonin against dimethylbenz(a)anthracene induced changes in renal tubules of Mice an Autoradiographic Study.

By : Margit Semmler1, Abdel-Baset M. Aref2 Abstract The present study aims to evaluate the possible preventive effect of melatonin against dimethyl-benz(a)anthracene (DMBA) induced cell proliferation and DNA synthesis in epithelial cells of cortical and medullary renal tubules in mice applying the method of quantitative autoradiography. Exposure to a single injection of DMBA (10mg/ 100g […]

Vol.1 No.3 -6 : Toxic effects of some pesticides on the enzymatic activities and spermatogenesis of the land snail Monacha cantiana.

By : Sharaf, H.M.*,Abd El-Atti M.S. and Salama, M.A. Abstract Laboratory studies have been carried out on the toxic effects of three different pesticides namely, Diazinon, Lambdacyhalothrin and Methomyl as poisonous baits against the land snail, Monacha cantiana. The activities of five vital tissue enzymes, as Catalase (CAT), Malondialdehyde (MDA), Aspartate transaminase (AST). Alanine transaminase(ALT) […]

Vol.1 No.2 -6 : Life cycle of Eimeria rhinopomi sp. nov. (Apicomplexa Eimeriidae) infecting lesser mouse-tailed bat, Rhinopoma hardwickii Gray, 1831 (Chiroptera Rhinopomatidae) in Egypt.

By : Fathy A. Abdel-Ghaffar1, Mohammed A. Shazly1,Ola H. El-Habit2 , Irene S. Gamil2,Reda M. Mansour2 Abstract Developmental stages of the life cycle of E. rhinopomi sp. nov. were described for the first time from the lesser mouse-tailed bat, Rhinopoma hardwickii in Egypt. 152 bats were collected from October 2012 to December 2014 and examined […]

Vol.1 No.2 -5 : Ultrastructural evidence of spermatogenesis in the rusty parrotfish, Scarus ferrugineus (Teleostei Scaridae).

By : T. El-Sayed Ali1*#, S. H. Abdel-Aziz1, Abstract This work analyses the spermatogenesis in the males of Scarus ferrugineus from histological and ultrastructural points of view. This study was carried out during the period of formation of spermatozoa thus being able to determine the pattern of spermiogenesis which is important for phylogenetic analysis. Histological […]
