Magnetic Treatment Of Salted Irrigation Water And Seeds: Its Effects On Vegetable Crop Yield And Nutrition Value Of Spinach (Spinacia Oleracea L)

Pot experiment was conducted in Qalin Center, Kafr El-Sheikh Governorate, Egypt under the natural conditions of greenhouse during the two growing winter seasons of 2020/21 and 2021/22. The experiment aims to evaluate the effect of two magneto-priming seed treatments (Un-magnetized seeds (U-MS) and magnetized seeds (MS), two magnetized water (Un-magnetized water (U-MW) and magnetized water (MW) under two levels of irrigation water salinity stresses (2500 and 5000 ppm) on seedling emergence, vegetative growth and productivity of spinach plants. The eight treatments laid out in completely randomized design (CRD) with three replications. Results show that sowing magnetized spinach seeds and irrigation pots with magnetized saline water (2500 or 5000 ppm) significantly out-performed sowing un-magnetized spinach seeds and irrigated with un-magnetized water for all tested vegetative growth parameters at the age of 15, 30, 45, and 55 days. Regarding magnetized seed treatment, the magnetized seed treatments significantly surpassed the untreated seed in all recorded leaves growth parameters (i.e., leaves numbers plant-1, leave length (cm), leave width (cm) and Leave Area (LA; cm2)), plant growth parameters (i.e., plant height (cm), plant fresh and dry weight in gram), root growth parameters (root length and width (cm), root fresh and dry weight in gram) and total chlorophyl (spam) at the age of 15, 30, 45, and 55 days. The percent of improvement, ranged from 2.95 to 20.92% in leaves growth parameters, 8.80-20.45% in plant growth, 13.21-17.18% in root growth and 4.40-4.82% in total chlorophyl in leaves. Similar positive effects were recorded under magnetized water compared to untreated water treatments. Where the positive effects, ranged from 3.17 to 39.96% in leaves growth parameters, 3.88-24.81% in plant growth, 27.77-66.01% in root growth and 1.95-6.48% in total chlorophyl in leaves at the age of 15, 30, 45, and 55 days. As well as both factors (magnetized seed or water) caused positive effects on nutrition value of  Spinach leaves. Results also show that, the magnetized treatments (seeds and water; T4) under 2500 or 5000 ppm salinity level significantly improved all the above-mentioned parameters compared to untreated treatment (T1) at 15, 30, 45 and 55 days. Under the conditions of this experiment, the results suggest applying irrigation with magnetized water and seeds can be recommended for reducing salinity stress which reflected in improvement productivity of spinach crops

Effects of Purslane Shoot and Seed Ethanolic Extracts on Doxorubicin-Induced Testicular Toxicity in Albino Rats

The clinical usefulness of anthracycline antineoplastic antibiotic, doxorubicin (DOX) is restricted since it has several acute and chronic side effects. The effect of doxorubicin (4 mg/kg b.w/week) without or with oral administration of purslane (Portulaca oleracea) shoot ethanolic extract (50mg/kg b.w./day) and purslane seed ethanolic extract (50mg/kg b.w./day) co-treatments for 6 weeks was evaluated in adult male rats. Serum testosterone luteinizing hormone (LH), follicle stimulating hormone (FSH) level were assayed. Testis lipid peroxidation (indexed by MDA) and antioxidants like glutathione (GSH), glutathione-S-transferase (GST), peroxidase (POX), superoxide dismutase (SOD), catalase (CAT) levels in testis were assessed. The data revealed a significant decrease in serum levels concentration of testosterone, LH and FSH levels in doxorubicin-injected rats. In addition, testis glutathione, glutathione transferase, peroxidase, SOD and CAT levels were decreased while lipid peroxidation concentration in the testis was increased as a result of doxorubicin injection. Co-administration of ethanolic purslane and seed extracts potentially improved the adverse changes in serum testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH) levels with an increase in testis antioxidants levels and reduction in lipid peroxidation. In conclusion, it can be suggested that dietary purslane extract supplementation may provide a cushion for a prolonged therapeutic option against DOX testicular toxicity without harmful side effects

CHEMOPREVENTIVE EFFECTS OF ZINGIBEROFFICINALEEXTRACT AGAINST ASPARTAME INDUCED NEPHROTOXICITY AND OXIDATIVE STRESS IN RAT MODEL

ABSTRACT Ginger (Zingiberofficinale) contains active phenolic compounds that have antioxidant, anti-cancer, anti-inflammatory and antithrombotic properties. The aim of the present study was to evaluate the chemo protective effect of Z. officinale roots against aspartame inducedrat nephrotoxicity. The chosen dose of aspartame was adjusted to 0.2ml/ 25g b.wt. and was given three times per week for 12 weeks. Ginger aqueous extract were adjusted to 500mg/kg and were given three times per week for 12 weeks. Aspartame caused a marked rise in serum urea, creatinine and potassium level which improved by ginger extract pretreatment. Sodium level was decline in aspartame treated group that ameliorated through ginger extract pretreatment. Concerning oxidative stress and antioxidant defense system, ginger extract pretreatment successfully improved renal reduced glutathione (GSH) level, glutathione peroxidation (GPx) and superoxide dismutase (SOD) activities compared to aspartame treated group which give inverse results. However, while elevated lipid peroxidation (MDA) was noticed in aspartame treated rats, pretreatment with ginger extract produced a detectable decrease in lipid peroxidation level. The natural plant components may have chemo preventive effect against aspartame that induce nephrotoxicity and oxidative stress. However, further clinical studies are required to assess the safety and benefits of ginger root in human beings

PROTECTIVE EFFECTS OF ZINGIBER OFFICINALE AGAINST CARBON TETRACHLORIDE INDUCED LIVER FIBROSIS

Objective: Liver plays a pivotal role in regulating various physiological processes in the body such as metabolism, secretion, and storage. It has a great capacity to detoxify toxic substances and synthesize useful principles. The current study was designed to investigate the possible protective effects of Zingiber officinale (ginger) extract on liver fibrosis induced by carbon tetrachloride (CCl4) in rats.Methods: The animals were divided into four groups with eight rats in each. To induce liver fibrosis, Wistar albino rats received CCl4 (2 ml/kg diluted in corn oil) twice weekly for eight weeks. Rats were concurrently treated with Z. officinale extract at two different doses (300 and 600 mg/kg/day).Results: CCl4 ­­induced liver injury characterized by fibrotic changes, degenerated hepatocytes and focal accumulation of inflammatory cells. In addition, CCl4 administration produced a significant increase in serum aminotransferases, lipids, liver lipid peroxidation and nitric oxide. The hepatoprotective effects of Z. officinale extract were evidenced by the significant decrease in serum aminotransferases and liver lipid peroxidation. Further, concurrent treatment with either dose of Z. officinale enhanced liver glutathione and enzymatic antioxidant defenses.Conclusion: Z. officinale showed a marked hepatoprotective effect against CCl4–induced liver fibrosis and injury through the abolishment of oxidative stress and potentiation of the antioxidant defense system.Keywords: Antioxidant, Ginger, Fibrosis, Oxidative stres

Berberine mitigates methotrexate-induced oxidative stress and inflammation in the cerebrum of rats

Berberine is a natural isoquinoline alkaloid with multiple beneficial therapeutic effects. This study was designed to evaluate the protective effect of berberine against methotrexate (MTX)-induced oxidative stress and inflammation in the brain of rats. Rats received a single intraperitoneal injection of MTX (20 mg/kg) and orally administered 25 mg/kg and 50 mg/kg body weight berberine for 7 days. MTX-induced rats showed significantly increased lipid peroxidation and nitric oxide levels in the cerebrum. Treatment of the MTXinduced rats with berberine produced a significant decrease in cerebral levels of lipid peroxidation and nitric oxide. In addition, berberine induced a significant increase in reduced glutathione, superoxide dismutase, glutathione peroxidase and glutathione-S-transferase in the cerebrum of MTX-induced rats. Rats received MTX showed a significant up-regulation of nuclear factor-kappaB (NF-κB), inducible nitric oxide synthase (iNOS), tumor necrosis factor alpha (TNF-α) and interleukin-1beta (IL-1β) expression in the cerebrum, an effect that was significantly reversed following treatment with berberine. In conclusion, berberine protects against MTXinduced neurotoxicity through attenuating oxidative stress and inflammation, and boosting the antioxidant defenses

Evaluation of Salicornia bigelovii Germplasm for Food Use in Egypt and the United Arab Emirates Based on Agronomic Traits and Nutritional Composition

Climate change significantly aggravates the quality of soil and water, especially in desert regions such as the United Arab Emirates (UAE) and Egypt concluding in an alarming increase in salinity in the reservoirs of the natural resources. Saline farming rises as a promising solution, utilizing low-quality water and land resources to grow salt-tolerant varieties of conventional crops and halophytes. Samphire (Salicornia spp.) is among the most popular multi-purpose halophytes that are locally consumed in several countries around the world as a vegetable. Six Salicornia bigelovii genotypes (ICBA-2, ICBA-3, ICBA-4, ICBA-8, ICBA-9, ICBA-10) were evaluated for their agronomic performance and nutritional composition in Dubai in UAE and, for the first time, at the Red Sea Governorate in Egypt in the 2019–2020 season using saline groundwater for irrigation (ECw = 26 and 6.6 dS/m, respectively). ICBA-10 performed well in both locations with high green biomass and seed yield (10.9 kgm-2 and 116.3 gm-2, respectively, in UAE; 7.7 kgm-2 and 82.9 gm-2, respectively, in Egypt). ICBA-10 was, overall, also good in ion accumulation, total amino acids and unsaturated fatty acids content in both locations for shoots and seeds. Our results indicated that a lack of a drainage system and leaching fraction, the silt loam texture and the drip irrigation system might have contributed in the gradual accumulation of salts in the soil at Mubarak Valley at the end of the experiment at a higher level than ICBA. Apart from the agronomic parameters, higher salinity levels also affected ion accumulation, the amino acids and the fatty acids content for both shoots and seeds, whereas the proximate composition was affected to a lesser extent. Our findings on the high unsaturated fatty acids content under higher salinity corroborate the nutritional value of S. bigelovii oil. Due to its euhalophyte nature, S. bigelovii is a valuable source of minerals, amino acids and antioxidants that render it the most promising salt-loving plant for food use
