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) […]

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 […]

Vol.1 No.2 -4 : Microbiological and molecular studies on Salmonella spp. isolated from broilers in Kafr El-Sheikh governorate, Egypt.

By : Mohamed T. Shaaban 1, Hegazy , A.M 2,Sami I.Menisy 3 Abstract Prevalence of Salmonella pathogen in poultry in Kafr El – Sheikh governorate, Egypt were analyzed in 100 pooled samples from poultry (liver, spleen , cloacal swab, gall bladder ), using culture and PCR based methods. The results showed that S. enteric was […]

Vol.1 No.2 -1 : Clomiphene citrate induced kidney injury in female albino rat.

By : Hawazen A. Lamfon1 and Nahid A. Lamfon2 Abstract Clomiphene citrate (clomid), a selective oestrogen-receptor modulator, is used in the treatment of polycystic ovary syndrome. On the other hand, it showed many adverse effects. The present work investigates the effects of clomiphene citrate (CC) on kidney of female albino rats. Many biochemical and histological […]
