The Impact of Nitrogen-Fixing Bacteria, Iron, and Zinc Foliar Application on Dry Land Yellow Mustard (Brassica juncea) Grain and Oil Production

The study, conducted at the Research Farm of the College of Agriculture, University of Tabriz in 2021, focused on the effects of various nitrogen-fixing bacterial isolates, biofertilizers containing nitrogen and phosphorus, as well as iron and zinc foliar applications on mustard growth under rainfed conditions. The results indicated that biofertilizers, whether used alone or in combination with chemical fertilizers, produced comparable grain and oil outputs compared to chemical fertilizers alone. Additionally, the application of iron and zinc through foliar spraying significantly enhanced both grain and oil production. These findings suggest that integrating nitrogen-fixing bacteria and biofertilizers could reduce reliance on chemical nitrogenous fertilizers, leading to decreased production expenses, improved product quality, and minimized environmental impact. This study highlights the potential for sustainable agricultural practices in dry land farming as a viable alternative to traditional chemical-intensive methods. Substituting chemical nitrogenous fertilizers with nitrogen-fixing bacteria or biofertilizers could result in cost savings in mustard grain and oil production while promoting environmental sustainability.

We present a 26-year-old male with an avulsive wound in the right maxillary region, with no bone injuries, taken to the operative room performing a Mustardé Flap for reconstruction of the defect area. Patient completed a 7-day antibiotic regimen, using non-steroid anti-inflammatories for pain, wound cleaning and flap hydration with mineral oil, subsequently having an adequate clinical and aesthetic evolution. Conclusion: The Mustardé flap can be a useful pedicled flap for the reconstruction of full-thickness defects.

Lethal Effect of Benzene Nitrogen Mustard Glucoside Derivate on K562 Cells

A new synthesized benzene nitrogen mustard was converted into glycosyl donor-trichloroacetimidate that was glycosylated with p-nitrophenol（glycosyl donors） to form β-lactosyl p-nitrobenzene under the protection of acetyl in a stereoselective manner, was prepared and evaluated for its cytotoxicity towards cultured K562 cell line. Methylthiazoy tetrazolium（MTT） assay, transmission electron microscopy（TEM）, flow cytometry（FCM） and immunohistochemistry were utilized to explore the mechanisms of how the compound arrests the growth of HCT-T cells. This new synthesed benzene nitrogen mustard glucoside derivate（BNMGD） presented a lower toxicity to normal cells, but is significantly more toxic to K562 cells compared with nitrogen mustard, meanwhile it can induce the apoptosis of K562 cells. These results indicate that the new synthesized BNMGD can inhibit the growth of K562 cells and induce the apoptosis, and its cytotoxicity towards cultured K562 cell line is much more effective than that of nitrogen mustard.

Effect of Pest Exclusion Net(PEN)on the Sustainable Production of Late Season Broad Leaf Mustard(BLM)in Chitwan,Nepal

Broad leaf mustard(BLM)(Brassica juncea L.var.rugosa,Brassicaceae)is one of the most widely consumed vegetable crops in Nepal.The production of crop in open field is constrained by major pests like mustard aphid and flea beetle.This study was aimed to determine the effects of pest exclusion net(PEN)on pest-infestation and yield of BLM cultivar“Khumal Broad Leaf”.The experiment was carried out in randomized complete block design(RCBD)with five treatments and four replications.The treatments included control(no mulch+no net+no pesticide spray),black plastic mulch only,reflective plastic mulch only,black plastic mulch+no net+pesticide spray,and PEN+black plastic mulch+no pesticide spray.Data were analyzed with RSTAT software package and means were separated by Duncan’s multiple range test(DMRT)at 5%level of significance.The result revealed that crop under PEN had highest plant height(38.99 cm),lowest number of aphid(0-0.86 per plant),flea beetle(0-1.07 per plant)and highest total marketable yield(77.50 ton/ha)while control had lowest plant height(20.06 cm),highest number of aphid(maximum 2.49 per plant),flea beetle(maximum 2.00 per plant)and lowest total marketable yield(13.75 ton/ha).Economic analysis revealed highest benefit-cost ratio in PEN(9.90).This study indicates that the use of PEN protect BLM against aphid and flea beetle,increases yield and can be considered as a viable technology for BLM production by smallholder growers of Nepal.

Prophylactic Effect of Gossypin Against Percutaneously Administered Sulfur Mustard

Objective To evaluate the protective efficacy of gossypin （3,3＇,4＇,5,7,8-hexahydroxyflavone 8-glucoside） by administering it intraperitoneally, for dose, time, and vehicle dependent effects against sulphur mustard （SM）, administered through percutaneous route in mice. Methods SM （diluted in PEG-300） was administered percutaneously. The protective efficacy of gossypin was evaluated by administering it intraperitoneally （50, 100, 200, and 400 mg/kg）, in various vehicles （water, PEG-300 and DMSO）, and time intervals （30 min prior, simultaneous and 2 h post）. The time dependent protection of gossypin （200 mg/kg in PEG-300; i.p.） was also evaluated using selected biochemical variables （GSH, GSSG, MDA, total antioxidant status, Hb, WBC count, RBC count, glutathione peroxidase, glutathione reductase, and superoxide dismutase） and liver histology. The protection of gossypin by oral route was also evaluated against percutaneously administered SM. Results The protection against systemic toxicity of SM （LD50 8.1 mg/kg） was better when gossypin was given with PEG-300 （8.0 folds） than DMSO （5.7 folds）. No protection was observed when gossypin was administered with water. Good protection （8.0 folds） was observed when gossypin was administered （200 mg/kg in PEG-300; i.p.） at 30 min prior or simultaneous to SM exposure, but no protection was observed when gossypin was administered 2 h post to SM exposure. A significant weight loss was observed 7 days after SM administration （2 LD50）, with a significant increase in RBC and Hb. A significant decrease in total antioxidant status of plasma, liver GSH and GSSG levels, and in the activities of glutathione peroxidase, glutathione reductase and superoxide dismutase was also observed 7 days after SM administration. SM treated mouse liver also showed necrosis. A significant protection was observed when gossypin （200 mg/kg in PEG-300; i.p.） was administered either as a pretreatment （30 min before） or simultaneous treatment, and not as a post treatment （2 h）. The protective efficacy of gossypin was better through oral route when administered with DMSO （4.8 folds） than with PEG-300 （2.4 folds）. No protection was observed when gossypin was administered orally with water. Conclusion Percutaneous administration of SM induces oxidative stress and gossypin can protect it as a prophylactic agent by intraperitoneal or oral routes.

Sulphur Mustard Induced Oxidative Stress and Its Prevention by Sodium 2, 3-Dimercapto Propane Sulphonic Acid (DMPS) in Mice

Sulphur mustard [bis(2 chloro ethyl) sulfide] (SM), a bifunctional alkylating agent has been frequently used as a chemical warfare agent. In the present study, the effects of sodium 2 3 dimercaptopropane sulphonic acid (DMPS) on some biochemical and histological parameters in mice, exposed to 1/4LC 50 concentration of SM vapor (10.5 mg/m\+3) were examined over a period of seven days. Exposure of SM resulted in a significant loss of blood, hepatic and pulmonary glutathione (GSH) and an elevation of hepatic and pulmonary oxidized glutathione (GSSG). These biochemical changes were accompanied by a number of histopathological alterations. The most prominent was congestion and degeneration in viscera and obliteration of chromatin material. These biochemical and histopathological changes were less marked in animals pre administered with DMPS followed by DMPS exposure indicating some protective value of the thiol (DMPS) against SM induced oxidative injury in mice.

Histomorphological and Histochemical Alterations Following Short-term Inhalation Exposure to Sulfur Mustard on Visceral Organs of Mice

Toxic effects of inhaled sulfur mustard (SM) on the histology of visceral organs was investigaed by exposing mice to 84. 6mg/m3 for 1h duration, using controlled single exposure conditions. A progressive fall in body weight from third day onwards was noticed. Light microscopic examination of the pulmonary tissue of these animals at 6 h post exposure revealed that the tracheobronchial epithelium remained intact, but was infiltrated by inflammatory cells. By 24 h post exposure, the mucosecretory cells were destroyed. The indanunatory reaction was maximum at 48 h. By 7th day post exposure there was swelling and vacuolation of lung parenchymal cells and thrombi formation. In addition SM caused congestion and hemorrhage at alveolar level. SM also caused granulovacuolar degeneration with perinuclear clumping of the cytopasm of hepatocytes and renal parenchymal cells. Renallesions were chazacterized by congestion and hemorrhage. Among visceral tissues, maximum atrophywas observed in spleen. Distribution of lesions increased with post exposure period. The maximum lesions were observed at 7th day post-exposure.

Distribution of cadmium in oilseed rape and Indian mustard grown on cadmium contaminated soil

Heavy metal distribution in the specialized accumulating plants was important for phytoextraction technique. Hydroponic and pot experiment were conducted to investigated Cd phytoextraction ability and Cd distribution in the plant of oilseed rape species. The results showed that oilseed rape Chuanyou Ⅱ-10 was more effective in phytoexetraction Cd among 21 varieties of oilseed rape and indicator plant Indian mustard. Cd concentration in the shoot of Chuanyou Ⅱ-10 and Indian mustard gradually decreased with an increase in growth period, while the amount of Cd uptake increased with the increase of growth period. There was constantly decrease in Cd concentration from the base leaves to the top leaves of Chuanyou Ⅱ-10 and Indian mustard, the percentages of Cd uptake in older leaves were higher than those of younger leaves. Older leaves of Chuanyou Ⅱ-10 and Indian mustard extracted more Cd for the Cd contamination soil, leaves should as far as possible develop before they reached the soil and the older leaves were harvested in priority.

The injury progression of T lymphocytes in a mouse model with subcutaneous injection of a high dose of sulfur mustard

Background: In clinical studies, the findings on sulfur mustard(SM) toxicity for CD3+CD4+ and CD3+CD8+ T lymphocyte subsets are contradictory. In animal experiments, the effect of SM on the T cell number and proliferation is incompatible and is even the opposite of the results in human studies. In this study, we observed the dynamic changes of T lymphocytes in the first week in a high-dose SM-induced model.Methods: Mice were exposed to SM by subcutaneous injection(20 mg/kg) and were sacrificed 4 h, 24 h, 72 h and 168 h later. Spleen T lymphocyte proliferation was evaluated by 3H-Td R. Flow cytometric analysis was used to observe the percentage of CD3+CD4+ and CD3+CD8+ T lymphocyte subsets. The IL-1e assayed using the Luminex method. DNA damage in bone marrow ceβ, IL-6, IL-10 and TNF-lls was observed with α levels in plasma werthe single cell gel electrophoresis technique(SCGE).Results: SM continuously inhibited the proliferation of lymphocytes for 7 days, and there was a significant rebound of Con A-induced T lymphocyte proliferation only at 24 h. The percentage of CD3+CD4+ and CD3+CD8+ lymphocytes was upregulated, which was accompanied by increased IL-1β and TNF-creased in the PG group at 4 h. The peak of lymphocytic apoptα and decreased IL-10. The IL-6 level was gradually deosis and DNA damage occurred at 24 h and 72 h, respectively. Conclusion: Our results show that SM significantly inhibited T lymphocyte proliferation as well as induced CD3+CD4+ and CD3+CD8+ upregulation. SM intoxication also significantly increased the levels of pro-inflammatory cytokines(IL-1β, IL-6 and TNF-α) and inhibited the level of anti-inflammatory cytokine IL-10. Our results may partly be due to the significant SM induced significant apoptosis and necrosis of lymphocytes as well as DNA damage of bone marrow cells. The results provided a favorable evaluation of SM immune toxicity in an animal model.

A full-scale experimental study of treating mustard wastewater by the integrated bioreactor with designed scale of 1 000 m3/d is conducted combined with a demonstration project. The systematical researches on the efficiency of combined operation conditions of anaerobic-aerobic and anaerobic-aerobic-flocculation as well as chemical phosphorus removal of hypersaline mustard wastewater are conducted. The optimal operation condition and parameters in pretreatment of mustard wastewater in winter （the water temperature ranges 8-15 ~C） are determined： the anaerobic load is 3.0 kg （COD）/（m3.d）, the average COD and phosphate concentration of the inflow are respectively 3 883 mg/L and 35.53 mg/L and the dosage of flocculent （PAC） is 400 mg/L. The anaerobic-aerobic-flocculation combined operation condition and postpositive phosphorous removal with ferrous sulfate are employed. After treatment, the COD of the effluent is 470 mg/L and the average phosphate concentration is 5.09 mg/L. The effluent could achieve the third-level of Integrated Wastewater Discharge Standard （GB 8978--1996）.

Cloning and Sequencing Characteristics of rDNA ITS Region of the Pathogen Causing Black Spot Disease on Tumorous Stem Mustard

Taking tumorous stem mustard infected by black spot disease as the research material, the ribosomal 5.8S rDNA and its flanking ITS region were cloned, sequenced and aligned in the study. The results showed that the base sequence of pathogens collected from five different sites was almost identical with that of Alternaria brassicae, and the similarity degree reached 99.68%, without base difference greater than 3 bp. It had obvious differences with the sequences of A. brassicicola and A. japonica, and the base difference was greater than 3 bp with a lot of fragment deletions. It was preliminarily determined that the pathogen cau- sing black spot disease on tumorous stem mustard was A. brassicae.

<i>In vitro</i>Bile Acid Binding of Mustard Greens, Kale, Broccoli, Cabbage and Green Bell Pepper Improves with Sautéing Compared with Raw or Other Methods of Preparation

Bile acid binding potential of foods and food fractions has been related to lowering the risk of heart disease and that of cancer. Steam cooking has been observed to significantly improve bile acid binding of green/leafy vegetables. It was hypothesized that other cooking methods could further improve the bile acid binding of various vegetables. Sautée cooking resulted in in vitro bile acid binding measured on a dry matter basis relative to cholestyramine of 14% for mustard greens and kale, 9% for broccoli, 8% for collard greens, 6% for cabbage, and 5% for green bell pepper. These results point to the significantly different (P ≤ 0.05) health promoting potential of mustard greens = kale > broccoli > collard greens > cabbage > green bell pepper. Sautéing significantly improved in vitro bile acid binding of mustard greens, kale, broccoli, cabbage and green bell pepper compared with steaming, boiling or raw (uncooked). Collard greens exhibited significantly higher bile acid binding by steaming compared with sautéing, boiling or raw. Data suggest that the cooking method with most heath promoting potential for mustard greens, kale, broccoli, cabbage and green bell pepper should be sautéing. Steaming should be used for collard greens as the cooking method. These green/leafy vegetables, when consumed regularly after sautéing, would promote a healthy lifestyle and have the potential to lower the risk of premature degenerative diseases.

Quantity of Fertilizer for a New Late-maturing Heading Mustard(Brassica juncea) Cultivar Yongbao 2 at the Heading Stage

[Objective] The study was to determine the optimal quantity of fertilizer required for Yongbao 2 during heading. [Method] According to a randomized block design with three replicates, four fertilizer treatments and one blank control were set in field trials. Each plot had a net area of 66.7 m2, Finally, the mustard yield and economic benefit per plot among the treatments were compared. [Result] There was no significant difference in yield among the four fertilizer treatments. The agronomic traits and yield of Yongbao 2 were improved when the quantity of fertilizer was gradually increased. The treatment with 750 kg/hm2 compound fertilizer during mus- tard heading had the highest yield. However, the treatment with 450 kg/hm2 of compound fertilizer during mustard heading had the highest economic benefit. By considering both yield and benefit, 450 kg/hm2 was the optimal quantity of fertilizer required for Yongbao 2 during heading. [Conclusion] The results will provide references for future application and extension of Yongbao 2.

Evaluation of CC2 as a Decontaminant in Various Hydrophilicand Lipophilic Formulations Against Sulphur Mustard

Objective To evaluate CC2 (N, N’-dichloro-bis [2, 4, 6-trichlorophenyl] urea) invarious hydrophilic and lipophilic formulations as a personnel decontaminant for sulphurmustard (SM). Methods Twenty percent of CC2 was prepared as a suspension or ointmentwith various chemical agents and its stability was evaluated by active chlorine assay. Theefficacy was evaluated in mice by recording the mortality after applying 29 LD50 of SM (LD50 =8.1 mg/kg dermally) and decontaminating it after 2 min with 200 mg of the formulation.Studies were also carried out with 10% and 20% CC2 in acacia and hydroxypropyl cellulose,and the suspensions were stored in polyethylene containers. The stability of the suspensionswas evaluated by active chlorine assay. The efficacy was evaluated by recording themortality after applying 29 LD50 of SM in mice and 12 LD50 of SM in rats (LD50 = 2.4 mg/kgdermally), and decontaminating it with the formulations. LD50 by different routes andprimary skin irritation test of CC2 were also carried out. Results CC2 reacted with peanutoil and neem oil, and was unstable in povidone iodine and Fuller’s earth. Good stability wasachieved with petroleum jelly, honey, polyvinyl pyrrolidone, calamine lotion, acacia andhydroxypropyl cellulose. Though CC2 was stable in lipophilic formulations, it did notprotect the animals. The hydrophilic formulations particularly acacia and hydroxypropylcellulose gave very good protection and was stable in the polyethylene containers for aperiod of 1 year. The efficacy of 20% CC2 was better than 10% CC2. The oral and dermalLD50 of CC2 was found to be above 5.0 g/kg. CC2 was also found to be nonirritant.Conclusion Twenty percent of CC2 in hydroxypropyl cellulose is better with respect tostability, efficacy and ease of decontamination. CC2 is also a safe chemical.
