The aim of this study was to examine the cytotoxicity of the herbicide atrazine on the reproductive system. 48 male and 48 female albino rats were treated with atrazine daily for two different durations (15 and 30 days). Reproductive system toxicity was monitored by quantitative analysis of the serum Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), Prolactin (PRL), Estrogen (E2), Progesterone (Prog) and Testosterone (Testo). On the other hand, the reproductive organs were collected for histopathology study. The study showed a significant elevation of estrogen, progesterone hormones with a significant decrease in testosterone hormone in male groups while in female groups there was a significant decrease in estrogen, progesterone & hormones with a significant increase in testosterone hormone. But there was no effect on PRL and LH hormones in both male and female groups toxified by ATZ, in comparison to the control groups. In addition to that, the Light microscopic examination of the seminiferous tubule cells (st) showed vacuolations within seminiferous tubules (V), degeneration of spermatozoa formation and hemorrhage (hg) in the interstitial tissue. These effects were increased by increasing the dose or the time of exposure. By using ascorbic acid in the treatment of those effects, we find a significant improvement and detoxification of the atrazine effects on both hormonal tests and histological sections. From our study results, we concluded that there is a potential contribution of herbicide mixtures in the etiology of somebody's diseases, while ascorbic acid has beneficial effects as it tends to dampen atrazine toxicity, in albino rats.

Scorpions are terrestrial arthropods inhabiting deserts. Exomorghological studies play an important role in the identification of different scorpions' species. The current study deals with the ecomorphology of four species of scorpions belong to the family buthidae (Leiurus quinquestriatus, Androctonus amoreuxi, Orthochirus innesi and Buthacus leptochelys) inhabiting New Valley governorate, Egypt. Random samples were implemented during the period from April to July, 2017 and July to September, 2019. Scorpions were obtained from the area under rocks, gap of soil, leaf litter, under bark, and within vegetation. Morphological characteristics of these species were done using a scanning electron microscope (SEM). In conclusion, the differences among four species of studied scorpions were noticed in the dorsal carapace, respiratory pores of the third segment of mesosoma, pectinal teeth count between females and males, last segment of metasoma and telson. In all scorpions' species studied, one venom pore was detected except in Androctonus amoreuxi two venom pores in telson were observed.

The present work aims to investigate the effect of Chitosan (as a natural adsorbent) for removing five heavy metals from synthetic polluted water after different contacting periods to be suitable for aquaculture and other purposes. Three different concentrations: 5, 7.5 and 10 g / l of chitosan were tested for their removal efficiency for 1 ppm of Fe, Zn, Cu, Cd and Pb at different contact periods. The effect of different contacting periods (30 Min, 1, 3, 6, 12, 18 and 24 hours) was tested with the three investigated concentrations of chitosan on the removal efficiency of the five metals. It's revealed that the removal efficiency increases with the increase in the contracting period, where the lowest values of removal efficiency for Fe, Zn, Cu, Cd and Pb were 27.7, 48.4, 68.4, 22.2 and 88.3 %, respectively after 30 Minutes, while the highest ones were 95.2, 91.9, 89.1, 94.1 and 99.9 %, respectively after 24 hours. The equilibrium adsorption behaviour data were fitted well to Langmuir and Freundlich adsorption isotherm models. R2 for Langmuir values for removing the investigated metals ranged between (0.947 to 1), while for Freundlich R2 values ranged between (0.931 to 0.992). Isothermal studies proved that chitosan was highly potential for removing all metals from polluted water.

The externae of parasitic sacculind, Sacculina leptodiae (Sacculindae: Rhizocephala: Cirripedia) on the xanthid crab, Leptodius exaratus (Xanthidae: Brachyura) were recorded during this study. A total of 691 individuals (400 males and 291 females) of this crab were collected from the intertidal coasts of the Egyptian Red Sea, Gulf of Suez and Gulf of Aqaba, of them 38 (23 males and 15 females) were infected with this parasite. The overall infection rate recorded 5.50% for all populations and was slightly higher in males (5.75%) than in females (5.15%). It showed seasonal, spatial and sex variations, recorded the highest rate (7.91%) at Gulf of Suez, declined sharply to 3.85 % at Gulf of Aqaba, and 2.43 % at all populations of the Red Sea, recorded the minimum rate of 0.57% at the southern populations. Autumn has the highest rate (10.34 %) at Hurghada (northern Red Sea), followed by summer with 9.34 % and 7.69 % at the Gulf of Suez and Ras Mohammed (Northern Red Sea), respectively, declined to 2.94 % in summer at Gulf of Aqaba, but increased again to 5.56% during spring. A total of 41 externae were recorded on the infected individuals, comprised 35 individuals with single externa (92.11 %), and only three with double externe (7.89 %). The highest number of externae was 13 (31.70 %) occurred on the 6th abdominal segment, followed by 11 (26.82 %) on the 5th segments, declined to 1-5 on the other segments except the first. The size of externae varied from 1.0 to 10.4 mm in breadth, averaged 5.19± 2.76 mm in males and 5.63± 3.17 mm in females. The rootlets of internae of the parasite invaded ovaries, testes, hepatopancreas, and all spaces within the crab body cavities. The disappearance or destruction of testes in infected males accompanied by remarkable broadness and segmentation of abdomens fringed with dense and length setae lead to “Parasitic castration”, compared with a hyperfiminzation in infected females due to the destruction of undeveloped ovaries and increasing abdominal setae dense and length.

Two field experiments were conducted at El-Gemmeiza Agricultural Research Station, El-Gharbia Governorate, Egypt during the two seasons 2018 and 2019. The aim of this study was to investigate the efficiency of soaking seed and foliar spraying of humic acid, fulvic acid, Imidacloprid (Gaucho) and combinations of them on the cotton pests, growth, yield, and yield components of Giza 86 cotton varieties. The results showed that Gaucho and Gaucho+ Humic+ Fulvic gave the high reduction percentage of Thrips tabaci and Tetranychus urticae when the cotton seed soaking with these compounds compared with control. On the other hand, the high reduction percentage of Empoasca lybica was recorded when the cotton plant treated with a foliar spray by Carbosulfan+ Fulvic acid and Carbosulfan+ Humic + Fulvic acid were 82.0 and 87.76 %, respectively during the two seasons. In addition, the reduction percentage of Tetranychus urticae was 84.15, 83.44 and 81.38% for Chlorfenapyr+ Fulvic acid; Chlorfenapyr+ Humic + Fulvic acid and Chlorfenapyr, respectively. The effect of Chlorfenapyr on the total number of true spiders on cotton was studied. Also, results indicated that Gaucho treatments increased the Plant height at harvest, Number of fruiting branches/plant, number of open bolls/plant and Seed cotton yield compared to control as well as a traditional pest control method. Thus seed treatment of cotton crops with Imidacloprid can be an ideal strategy for IPM in the cotton field in Egypt.

This study aims to investigate Donax trunculus (D. trunculus) as a biomarker for heavy metals and total hydrocarbon contamination. To achieve this goal, we investigated the effect of 3 day-depuration on the accumulation levels of heavy metals and total hydrocarbons as well as the transcriptional variations in expressions of oxidative stress-related genes of Donax trunculus collected from El-Gameel region, Port Said, Egypt. After 3 day-depuration, all the accumulated tested heavy metals levels showed a considerable decrease (levels after depuration divide by levels before depuration) in D. trunculus tissues by 23%, 20%,72%,98%, 89%, 66% for Pb, Cd, Cu, Fe, Mn and Zn respectively. Additionally, the concentrations of total hydrocarbons in clam’s D. trunculus tissues were reduced to 95%. After 3 days of treatment, the results revealed that the Cat activity decreased to approximately 36% and expression of CYP gene had been up-regulated by about 38%, The Gst gene had been down-regulated by about 2-fold in D. trunculus. Additionally, Mt gene had been up-regulated to approximately 70% and SOD gene had been down-regulated to 50%. To conclude, accumulated heavy metals and total hydrocarbons measured before depuration in the soft parts of D. trunculus was higher than the standard worldwide acceptable limits leading to the hypothesis that D. trunculus in the investigated study area may not be safe for human consumption. Therefore, as a potential public health threat from the seafood diet, more research on the chronic toxic effects of heavy metals and total hydrocarbons in marine species are needed.

Many populations of amphibians are facing remarkable decline throughout the world. The reason for the decline is a direct response to habitat destruction and pollution including heavy metals. The blood of the toad is vascular and very plastic tissue. In fact, a variation of several hematological parameters in response to natural changes in the environment has been widely described previously. Since hematological parameters are influenced by a variety of environmental stressors, they have the potential to be used as biomarkers of aquatic pollution. Heavy metals are difficult to remove from the environment and cannot be degraded biologically. The current study assessed the impact of some heavy metals on hematological and serological parameters in the Egyptian toad (Sclerophrys regularis) from two different localities (North Giza and El Wahat regions). The current results have revealed a reduction in the means of RBCs, hemoglobin, and hematocrit values in addition to a remarkable increase in WBCs. In addition, the major serological parameters including protein, albumin, AST, and ALT were also altered in parallel with the deterioration that occurred between the two investigated regions. The present findings have revealed and confirmed that the Abu Rawash area is more impacted compared to El Bawiti.

Background: A solar eclipse is an occasional natural phenomenon that can alter the physical and biological processes of organisms. On 21 June 2020 a unique opportunity was offered to evaluate how birds change their behaviour during an eclipse. Bird behaviour was categorised using a scan-sampling technique before, during and after the solar eclipse, and at a different time of eclipse day. Results: Before the eclipse major activity categories were moving (52.45%), foraging (40.20%), and courtship (2.94%) respectively, but there were no roosting/resting observations at this time. These behaviours were much reduced during the eclipse, while roosting accounted for 14.6% of behaviour. When the eclipse began at 06:50, their calling and flying increased, and singing decreased. At maximum eclipse (07:20h), there was a profound decrease in calling, singing, foraging and moving, and courtship; while washing and floating were not observed. After the eclipse, most time was spent foraging (36.3%), followed by moving (flying), with roosting reduced to 2.4%. Conclusions: Clear and radical behavioural changes were observed when the eclipse was started and maximum. Responses of birds to the environmental factor changes associated with the solar eclipse might be the root cause of observed unusual behavioural change.

Tick infestation is the main issue for animal health that causes substantial economic losses in the form of mortality and morbidity, particularly in tropical and subtropical countries of the world including Pakistan. The rural economy of Pakistan depends upon on livestock industry which faces the problems of some zoonotic diseases spread by tick infestation. Tick infestation caused Crimean-Congo hemorrhagic fever (CCHF), Lyme disease, theileriosis and babesiosis in wild and domestic animals including humans. Climate change is highly associated with the distribution of ticks and ticks borne-diseases (TBDs). Due to global warming, the temperature of the globe is rising which directly and indirectly affects vector-borne diseases like TBDs. To minimize the ticks and TBDs various approaches have been used in different regions of the world including Pakistan. The need for a review paper is to investigate the impact of climate change on ticks and TBDs in livestock as well as public health in Pakistan. To evaluate the effectiveness, environmentally safe, economically feasible and acceptable tick management approaches, literature was reviewed.

The objective of this study was to analyze the potential toxicity of the Hydroxyapatite. 60 male albino rats were treated with Hydroxyapatite for 30 days. Toxicity was monitored by quantitative analysis of the serum testosterone hormone level; follicle-stimulating hormone (FSH) level in serum, luteinizing hormone (LH) level in serum, prolactin hormone PRL) level in serum, AST activity and Alkaline phosphatase activity was measured and tests were collected for histopathological study. The results refer to a significant decrease in testosterone; FSH, LH and PRL while a significant increase in AST and ALP). Histopathology revealed moderate disturbance with an irregular cycle of spermatogenesis in seminiferous tubules, a marked decrease in the number of spermatogenic cells in the seminiferous tubules, a marked decrease in the number of sperms and Leydig cells. The administration of the Chitosan had beneficial and decrease side effects against the deleterious changes of Hydroxyapatite. In conclusion, results suggest a potential contribution of Hydroxyapatite to the etiology of somebody's diseases while Chitosan has beneficial effects as it tends to dampen Hydroxyapatite toxicity in rats.

The rate of afforestation is increasing worldwide and has represented a common land use and a very important resource for centuries. The use of exotic species in the afforestation process may have a negative impact on ecosystem function and structure, including changes in shading, microclimate, nutrient cycles, and water balance, which may, in turn, affect biodiversity. The objective of this paper was to document and investigate the impact of forest plantations that use alien plants on the native ground-dwelling fauna, specifically using spiders as bioindicators. Spider species showed a great difference in both univariate measurements (diversity indices, richness and evenness) and multivariate analysis (species composition and indicator species). Five spider species were newly recorded in Egypt during this study; four of them were found in the forest habitat (Micaria dives, Odontodrassus aravaensis, Pholcus opilionoides and Scytodes univittata) while Halodromus patellidens was recorded in the control area. The experimental nature of this study confirmed that assessing the risks of forest plantation activities is urgently needed before introducing any species. It highlights the fact that the use of endemic trees is preferred in order to avoid altering native diversity.

This study is a part of an extended investigation that aims to clarify the nemastatic activity of two commercial formulations of resistance inducers; Bio-arc and Nemastrol against Meloidogyne incognita infected sugar-beet in vitro and in vivo. Generally, data indicate that the ability of all individuals of the stage juveniles to penetrate the roots and develop into the next stage with a shortage of the duration of the life cycle in sandy soil compared to clayey soil. The results showed that Nemastrol caused a significant reduction in the percentage of penetration of M. incognita at the second-stage juveniles. Bio-arc ranked the second one comparing to control in clayey and sandy soil. The duration of developmental four juvenile stages, as well as egg-laying females, have a clear reduction with Nemastrol in clayey and sandy soil more than Bio-arc comparing to control. The length of the life cycle varies, as treatments by Nemastrol were longer than Bio-arc in clayey and sandy soil (2-24 and 9-24 days), respectively. Besides, Nemastrol showed a poor formation of irregular giant cells devoided from the cytoplasm and contained less number of nuclei.

Background: Rodent repellent substances are chemicals that have taste, odors, or both that will prevent rats from feeding or gnawing. Effects of fresh or fermented clover plant juice were studied as a repellent against both sex black rat, Rattus rattus, under laboratory and stores (fertilizers and equipment stores) conditions in Giza Governorate. Each fresh and fermented clover plant juice mixed with crushed maize at 23.8% (the appropriate concentration) was tested as bait using non and free choice feeding methods. Results: The results revealed that fermented juice was more repellent than fresh juice for rats as it achieved 92.6% repellency comparing with 38.7% for fresh juice after 4 days of treatment. The bodyweight of rats reduced after treated with fermented bait while it increased with fresh bait. The fermented and fresh clover juices were analyzed on Gas Chromatography-Mass Spectrometry (GCMS). The chemical compounds analysis names were: Erythro- 3- bromo -2- pentanol and other compounds while Thero -3- bromo -2- Pentanol compound was found only in fermented juice. The concentrations of the recorded compounds in fermented juice were higher than those in fresh juice. On the other side, the fermented clover plant juice bait achieved 85.7% efficiency against black rat, R. rattus as a repellent in stores after one week of treatment. Conclusion: The fermented clover plant juice cussed repellent to the rodent. So, it can be used for protecting stores of different materials (equipment, electric cables and raw materials) from rodent attacks.

Aim: To evaluate the ability of red and white hibiscus (H) in improving the epithelial barrier in indomethacin-induced duodenal and colonic inflammation, compared with prebiotic and to investigate whether the red and/or white hibiscus can be used as natural prebiotic like agents. Methods: Histological, histomorphometric, histochemical demonstration for goblets cells and mucin intensity. Immunohistochemical demonstration of COX-2, and tight junctions (Claudin-1 and E-cadherin) were examined. Duodenal and colonic TNF-α, IL-6, IL-10, PGE2, MPO, MDA, TAC, besides, serum CRP were evaluated. Results: Indomethacin induced inflammation and ulceration in the duodenum and colon, with significant depletion in goblet cell count and mucin intensity. COX-2 was increased while claudin-1 and E-cadherin were significantly diminished. Tissue TNF-α, IL-6, MPO, MDA, and serum CRP were elevated significantly by indomethacin, while IL-10, PGE2 and TAC were reduced. Co-treatment with red H, white H, or prebiotics plus indomethacin improved significantly duodenal and colonic histoarchitecture, tissue contents of PAS cells, mucin, claudin-1 and E-cadherin, while COX-2 reduced. TNF-α, IL-6, MPO, MDA, and serum CRP were decreased significantly, while IL-10 , PGE2 and TAC were restored. Conclusion: The current research introduces red and white hibiscus as prebiotics-like agents because of their anti-inflammatory, antioxidant, or tight junctions modulating activities.

The aim of our study was to determine the effect of the dietary energy levels on the live body weight, testis volume and blood testosterone concentration in Ouled Djellal ram lambs throughout growth. The study lasted six months from post-weaning until the pubertal period at the Technical Institute Farms (I.T.E.L.V) Lamtar of Sidi-bel-Abbes (Western Algeria). After weaning, Twenty single-born Ouled Djellal ram lambs from 90 to 240 days old were weighed and allotted into two equal groups of Low energy (n = 10) or High energy (n = 10) nutrition plane. Each group received; in addition to a basal diet (good quality pasture) 200 g and 400 g of concentrate feed mixture containing barley (60%), corn (5%), wheat bran (37.5 %) and vitamin-mineral compound (2.5 %) by head-1day-1 respectively. Hay and water were provided ad libitum. Monthly measurements of live body weight, testicular volume and blood testosterone concentration of lambs were recorded. The results showed that the High energy group of lambs recorded a significantly higher live body weight compared to the lambs of low energy group (p <0.001). Whereas, the testicular growth indicated a gradual and linear increase for both groups (low energy and high energy) with significant differences (p <0.001). However, all measurements of the testis, live body weight, serum testosterone levels and age were positively correlated with one another of both low and high groups throughout the experiment. In conclusion, High-level energy supplementation can improve to enhanced development in Ouled Djellal ram lambs this may be due to its beneficial effect on the productive and reproductive performance of growing male lambs. Furthermore, using younger lambs may reduce production costs, accelerate the benefits of genetic selection, and allow earlier progeny and libido testing.

This study was designed to investigate the protective role of kefir and insulin consumption on cellular activities, histochemical components, histological architecture, and integrity of the liver by measuring IL-6 and TNF-α in high fat-fed STZ- induced diabetic male Wistar rats. From a cell biological and histochemical point of view, both kefir and insulin have beneficial various effects on cellular activities and the histochemical components such as DNA, RNA, total protein, collagen, polysaccharides, and phospholipids materials synthesis in the examined normal and diabetic hepatocytes of the male rats. Biochemically, kefir and insulin have various biochemical effects on the serum IL-6 and TNF-α levels. From a pathological point of view, we can say the beneficial various cell biological and histochemical effects of kefir, pathologically may make kefir, to some extent, completely repair all the pathological side effects of type1 diabetes on the hepatocytes in diabetic rats. Also, insulin repair some of the pathological side effects of diabetes on the hepatocytes. The positive results of using kefir and insulin in treating the pathogen effects of diabetes make it possible to obtain positive clinical applications/implications. Therefore, these positive results encourage us to continue working and complete the various long-term pre-clinical trials and clinical trials phases.

Liver fibrosis is the progressive accumulation of connective tissue in the liver, which can be caused by chronic liver injury of various etiologies. Moringa oleifera is a pan-tropical species is used in nurturing both animal and human as an excellent nutritive supplement. Colchicine is a plant that effective against gouty arthritis and other forms of rheumatic diseases (rheumatoid arthritis, familial Mediterranean fever, Bechet´s disease, etc. This study thrown light on the hepatoprotecitve effects of Moringa oleifera ethanolic leaves extract and colchicine on thioacetamide-induced liver fibrosis in rats. Liver function tests (serum ALT, AST, ALP, and Total protein) in addition to histopathological examination of the liver were performed. This study was carried out on a total number of 42 male albino rats were collocated into seven groups (6 rats per group). The experiment lasted for two months, through which all groups except for control and control positive were given Moringa oleifera ethanolic leaves extract and colchicine. Liver fibrosis was induced by intraperitoneal injection of thioacetamide (150 mg/kg) in groups II, V, VI &VII while other groups were injected with 0.9% normal saline of the same volume. Bodyweight was measured three times a week to detect the dose for each rat. The administration of thioacetamide leading a significant increase in serum liver enzyme level ALT, AST, ALP, and Total protein as compared to the control group, while treatment with colchicine and Moringa oleifera ethanolic leaves extract causing significant decreased serum liver enzyme level by (P<0.05) than the induced hepatic group. In general, there is no fundamental difference between groups V, VI, VII. Also revealed that the injection of thioacetamide (150 mg/kg) induced liver fibrosis characterized by a drastic decrease in total protein as compared to the control group by (P <0.05). The colchicine or Moringa oleifera ethanolic leaves extract was able to restore dysfunction. In general, the treatment with colchicine and Moringa oleifera showed good restore in biochemical function and histopathological of the liver. Also, we detected that there are no differences between them.

The present study was designed to determine the possible therapeutic effects of royal jelly against carbon tetrachloride (CCl4) induced oxidative stress and biochemical changes in the kidney of albino rats. A patch of 20 male albino rats averaged weights (190±10 g) at the beginning of the experiment were divided into 4 main groups according to the treatment and requirements of the experiment. The rats injected i.p. with CCl4 at a dose (1 mL/kg, 1:1 in olive oil) twice per week and received, via gavage, royal jelly at a dose (400 mg/kg b. wt) along the experimental period. Each group contains 5 rats that were sacrificed on the45 days from the start of the experiment. The results refer to a significant elevation of renal parameters (creatinine, blood Urea and Uric acid) on the 6th week in rats injected intraperitoneal with CCl4 as compared to the control groups. The administration of the royal jelly has beneficial and decrease side effects against the deleterious changes of CCl4. In conclusion, according to the results obtained the administration of the royal jelly provides considerable nephroprotective effects against intoxicated with CCl4 in male Wister albino rats by preventing oxidative stress through ROS scavenger and improvement in the former biochemical parameters.
