Fenthion is a widely used organophosphorus pesticide in agriculture that induces different cytotoxic effects, including male reproductive toxicity. The present work aimed to study the ameliorative effects of curcumin, a potential therapeutic agent against several chronic diseases, on reproductive toxicity induced by the organophosphate insecticide fenthion. Forty adult male albino rats were divided into four groups. The control group received distilled water. The curcumin group was administered curcumin at a dose of 100 mg kg?1 body weight. The fenthion group was administered fenthion at a dose of 0.001 mg kg?1. The fenthion/curcumin group was administered fenthion and curcumin together at the same doses. After four weeks of daily oral administration, the animals were sacrificed and their testes were excised. Specimens were processed for histopatholological and immunohistochemical investigations. Light and electron microscopic analysis visualised dramatic degenerative changes in seminiferous tubules as indicated by atrophy, necrosis, vacuolation and decreased number of spermatogenic cells. Moreover, the fenthion group showed a significant reduction in the proliferating cell nuclear antigen (PCNA)-immunoreactivity. Decreased PCNA-immunoreactivity reflected the depletion in the proliferation rate of spermatogenic cells and suggesting arrested spermatogenesis. Curcumin administration to fenthion-treated rats revealed mild degenerative changes with partial improvement of active spermatogenesis. In conclusion, these data may confirm the cytoprotective potency of curcumin against fenthion-induced cyto-toxicity. 相似文献

Over the last two decades, the highly pathogenic avian influenza H5N1 virus has gained a lot of attention due to its zoonotic and mutative nature. Iran is among the countries significantly affected by the virus as it hosts migratory birds during seasonal migration. In this study, the molecular characterizations of hemagglutinin (HA) and neuraminidase (NA) genes and proteins of H5N1 strain A/chicken/Iran/8/2015 detected in backyard poultry, Mazandaran province, were investigated. Phylogenetic analysis classified this virus as a member of subclade 2.3.2.1c, with the cleavage site motif of “PQRERRRK-R/GLF”. HA carried a few mutations altering affinity to mammalian cells; however, the virus was categorized as avian. NA protein had the 20-amino acid deletion at aa position 49–69 similar to those isolated since 2000. Mutations of H253Y and H274Y contributing to antiviral resistance were present in NA. From this analysis, it can be concluded that the wild migratory birds flying from Western Asia to Eastern Africa are probably the main carriers of seasonal H5N1 in the country.

The cultivated varieties and landraces of Cucurbitaceae growing in Egypt are presented, 27 taxa, belonging to three genera, six species, and five subspecies. These characters are arranged according to their usefulness for identifications as follow: fruit characters, seed characters and trichome type. Fruit characters are a good taxonomic tool at varietal level when combined with the other vegetative characters. Two keys to 27 cultivated varieties of Cucurbitaceae (Cucumis, Cucurbita and Luffa) were constructed using the DELTA software system. One key is used for identification, and then the other is used as a confirmatory key. Those keys were built using 36 morphological characters include vegetative, floral, fruit and seed characters. There is a significant correlation between seed size and growth parameters. The growth parameters of the studied taxa included leaf length/size, petiole length and corolla length. There is a highly positive, significant correlation between seed volume and leaf size (r = 0.81831, P ≤ 0.001), seed volume and petiole length (r = 0.79112, P ≤ 0.001), seed volume and leaf length (r = 0.83566, P ≤ 0.001), and seed volume and corolla length (r = 0.59108, P ≤ 0.001). 相似文献

The induction of estrus during the non-breeding season was investigated in 100 Egyptian Baladi goats (Capra hircus). All animals assigned to treatments had low progesterone concentrations (<0.5 ng/ml) tested 2 times 10 days apart to confirm anestrous condition. Animals were assigned to three experimental groups. A group of animals received subcutaneous norgestomet ear implant for 11 days and a single i.m. injection of PGF2alpha 24 hr before implant removal (group I; n=40). Second group of animals received subcutaneous norgestomet ear implant for 11 days and a single i.m. injection of PGF2alpha 24 hr before implant removal and gonadotropin releasing hormone 24 hr after implant removal (group II; n=40). Third group of animals received no treatment (control group; n=20). The percentage of goats that showed estrous behavior during the first 72 hr after implant removal was 77.5, 85.0% and 10.0% in group I, group II and control group, respectively. The fertility rate was 57.5, 70.0% and 10.0% in group I, group II and control group, respectively. In conclusion, estrus can be induced in seasonally anestrous Egyptian Baladi goats using norgestomet and PGF2alpha and the injection of GnRH 24 hr after norgestomet implant removal synchronized ovulation in a higher percentage of goats. 相似文献

First and second derivative ultraviolet spectrometric methods are described for the estimation of indomethacin, naproxen, and ibuprofen in pharmaceutical dosage forms. The proposed methods permit the rapid, precise, and accurate determination of indomethacin capsules BP, naproxen capsules, and ibuprofen tablets BP. Matrix interference is successfully corrected. The results obtained by first and second derivative techniques are in accord with those obtained by the official assay method. 相似文献

Clinical signs of heat intolerance (panting) syndrome were observed in Holstein cows in a private farm in Egypt. There were heat intolerance (fever), panting, profuse salivation, hirsutism, lameness and reduced milk production. Blood and serum samples were collected from ten diseased cows and five apparently healthy cows as control. Serological tests confirmed the presence of non-structural protein of foot-and-mouth disease (FMD) infection. There were significant reductions in the total red blood cell count with increased leucocytic and lymphocytic counts in diseased group compared to control. The serum Na, Cl, Ca, Mg, Zn and Fe were significantly reduced but P was increased in diseased animals compared to control. The total protein, albumin, cholesterol and cortisol were significantly reduced but the glucose and malonaldehyde were significantly increased in diseased cows. This was the first report in Egypt to describe the clinical and haemato-biochemical changes in panting syndrome following FMD. 相似文献
